Above-mentioned saidaddress book 13 is important composition modules ofserver end 1; It is to be ranked with horizontal field by user longitudinally to rank the list of data structures that constitutes; As shown in Figure 5; The name of user name list storage registered users, such as user A, user B ..., user N, corresponding each user name of all kinds of field store such as " password, buddy list, blacklist, picture/multimedia gallery, time option, privacy options " etc.; The corresponding one group of corresponding field of each user name, " password " field that for example user A is corresponding is A_x, " buddy list " field is A₁, A₂..., A_n, " blacklist " field is A_H1, A_H2..., A_Hn, corresponding " password " field of party B-subscriber is B_x, " buddy list " field is B₁, B₂..., B_n, " blacklist " field is B_H1, B_H2..., B_Hn, the rest may be inferred, each user's information and field data all are stored in the list of data structures ofaddress book 13, its in the present invention role will have more detailed description hereinafter.

Then, like Fig. 2 and combine shown in Fig. 3 b, the sender then can get into and use the picture/multimedia processing module 12 (S403) of server end 1 according to the legal number of the account success logon server end S306 of registration just now.The sender can be through the picture/multimedia in the picture storage element 221 of selecting to be stored in the picture/multimedia processing module 22 of sending client 2; Picture/multimedia file that needs are sent is preserved through picture uploading unit 222 end 1 that uploads onto the server; In the picture storage element 122 of picture/multimedia processing module 12 that picture that sends or multimedia file are kept at server end 1, and this picture/multimedia processing module 12 also comprises picture editor unit 121 and picture transmitting element 123.Wherein, preserved all pictures and multimedia file that the sender uploads in the picture storage element 122, can carry out various editors to it through picture editor unit 121 users, such as operations such as interpolation, deletion or modifications.Then the sender can select to continue to upload other new picture/multimedia S404 through picture uploading unit 222; Or send through picture transmitting element 123 that existing picture/multimedia S407 gives the good friend in the picture storage elements 122; It should be noted that; Here " transmission " of indication is not really on the physical significance to form this picture/multimedia in another picture storage element that sends to good friend's number of the account place server end with file; And just this picture/multimedia information has been added in sender's " picture/multimedia gallery " field in the address book 13 of server end 1; And added a label that ability is collected by this good friend for this picture/multimedia file; Show that the good friend that this picture/multimedia can the person of being sent out be authorized reads and downloads, such as user A after having sent several picture/multimedias, in " picture/multimedia gallery " field respectively with P_A1, P_A2..., P_AnThe expression, in " picture/multimedia gallery " field of user B with P_B1, P_B2..., P_BnExpression, the rest may be inferred, with reference to shown in Figure 5.

Then; In above-mentioned selection step S403; If the user has selected step S404, shown in Fig. 4 b, then in thepicture storage element 221 that sendsclient 2, select required picture/multimedia S405; Submit to upload request S406 to upload new picture/multimedia step throughpicture uploading unit 222, be stored in after picture/multimedia is uploaded in thepicture storage element 12 ofserver end 1 with completion.

Especially; System of the present invention propagates the secondary of receiving file in order to stop the recipient, and also thepicture transmitting element 123 atserver end 1 is provided withprivacy options piece 1232, so that the fail safe of file propagation improves greatly; Because to some picture/multimedia file; The sender only is ready that the recipient watches, and be unwilling picture or the multimedia person of being received carry out secondary and propagate, and system of the present invention is provided withprivacy options piece 1232 backs just can prevent the generation that secondary is propagated fully.After selecting secret the transmission, picture/multimedia that the sender sends can only let the recipient play, and can not preserve at recipient's local disk, if unclassified transmission, the recipient both can watch also and can preserve the picture/multimedia that sends over so.Therefore, in above-mentioned selection step S403, if the user selects step S407, then please refer to shown in Fig. 4 c, whetherprivacy options piece 1232 can the prompting user select the secret S408 of transmission.

If what the user selected is unclassified transmission; " privacy options " field of address book 13 is record and this picture of label/multimedia file S416 earlier; Promptly " privacy options " field according to user just now selection result be unclassified transmission with this picture/multimedia file label; Get into instant forwarding step S417 then; Follow the object that the sender can select this picture/multimedia file to receive from the buddy list field of address book 13, behind the object S418 of selective reception, the time option piece 1231 of picture transmitting element 123 can require the sender to select " sending immediately " or " timed sending " S419; The result who selects carries out label S420 by " time option " field of address book 13 to this picture/multimedia file; Promptly " time option " field can write down and the label sender to this picture/multimedia transmitting time requirement, if " immediately send " then this picture/multimedia submit to server end 1 send request S421 after, picture transmitting element 123 can send to the recipient with this picture/multimedia at once; The words of " if timed sending "; Then after submit to sending request S421, picture transmitting element 123 can according to time that time that the sender requires send this picture/multimedia (after spending 1 hour or N hour, redispatch, or * * time * * minute send).

What the user selected when at step S408 is to maintain secrecy when sending, and then theprivacy options piece 1232 ofserver end 1 will be encrypted S412 to the content of picture or multimedia file earlier.Afterprivacy options piece 1232 has been encrypted picture file or multimedia file; To go to above-mentioned steps S416; " privacy options " field record and this picture of label/multimedia file S416 byaddress book 13; Promptly " privacy options " field is sent this picture/multimedia file label according to user's just now selection result for maintaining secrecy, and gets into the series of steps behind the above-mentioned instant forwarding step S417 then, at this repeated description no longer.

Then; Please refer to shown in Fig. 4 b; When the judged result at step S507 is that Query Result has new picture; Then queryrequests module 42 new picture/more multimedia attributes that this Query Result is comprised and the label informationpicture analyzing unit 431 that goes to the picture/multimedia processing module 43 that receivesclient 4 carries out pictorial information and analyzes S508; Analysis is meant to be discerned incidental attribute of these new picture/multimedias and label information; Belonging to " sending immediately " such as this picture/multimedia " time option " field still is " timed sending ", and it still is " unclassified transmission " that " privacy options " field of this picture/multimedia label belongs to " maintain secrecy and send ".Picture analyzing unit 431 can obtain the pictorial information tabulation S509 that will download according to various attributes that obtain from above-mentioned " picture/multimedia gallery " field and label information; Follow the transmission data S510 that picturedownload unit 432 will be downloaded according to above-mentioned download list elder generation encryption of obtaining,picture download unit 432 begins to download these new picture/multimedia file S511 more then.

After download finishes; Picture/themultimedia playing module 44 that receivesclient 4 will be earlier according topicture analyzing unit 431 acquisition download pictures or multimedia various attribute and label information judged whether the sender once selected to maintain secrecy S512 is set when sending picture or multimedia just now before these new pictures of broadcast or multimedia.

If the judged result of above-mentioned steps S512 is for denying; Just the sender had not selected to maintain secrecy to this picture/multimedia file and had sent; Picture/multimedia file of then downloading through above-mentionedpicture download unit 432 will be kept in thepicture storage element 433 that receivesclient 4; And playing just now picture or the multimedia S513 that downloads throughordinary playing unit 441, the recipient can view and admire, preserve and duplicate this picture or multimedia arbitrarily.

If the judged result of above-mentioned steps S512 is for being; Just the sender once selected to maintain secrecy to this picture/multimedia file and sent; Then before playing, will judge whether this document is multimedia file S514 earlier through trick-play unit 442; If judged result is not for, just this document is picture file rather than multimedia file, for prevent picture by screen copy (such as on the keyboard of computer through carrying out full frame copy by the PrintScreen key); Trick-play unit 442 is with the function S515 of first shield keyboard screen copy key; Play S517 through 442 pairs of these pictures in trick-play unit again, make the recipient watch picture and can not preserve or duplicate, thereby prevented that effectively picture from illegally being obtained by undelegated recipient; If the judged result of step S514 is for being; Just the sender sends when being multimedia file rather than picture file; For protecting multimedia file without approval by any copy propagation; The preservation and the copy function S516 of multimedia file will be forbidden in trick-play unit 442; Play this multimedia S517 through trick-play unit 442 again, picture or the multimedia file that sends of selecting to maintain secrecy can not be stored in the picture storage element 433 that receives client 4, thereby prevented that the recipient from preserving arbitrarily or duplicating picture or content of multimedia under uncommitted situation yet.

Adopt system and method for the present invention; Behind sender's logon server end; The picture that will send uploads to server end; The recipient is through behind the logon server end, and the picture or the multimedia file that will automatically other users be sended over through communication network download on the local reception client, and then play in desktop background.Because everything all is that Automatic Program is carried out; The user feels that similarly being is that the sender directly sends to picture or multimedia file on his screen background; Because the user need not do the operation of any download and broadcast, picture or multimedia file are play with regard to downloading to desktop background automatically.Wherein,, can also protect this picture or multimedia file not to be preserved wantonly or to duplicate, and can only supply the recipient to watch, in order to avoid file is propagated by illegal if the sender selects to maintain secrecy when sending to send.

In addition, what here will remark additionally is, in the present embodiment; Send client and can exchange, that is to say, as original sender in the transmission client with the position that receives client; As long as the reception client has been installed; It also can receive picture/multimedia as the recipient simultaneously, and former before this recipient who receives client, as long as the transmission client has been installed; It can send picture/multimedia file as the sender simultaneously, and being not limited to certain user can only be sender or recipient's identity.

Second embodiment

In the description of first embodiment; Sender and recipient utilize server end as a terminal with picture or multimedia file transmission and reception; If the sender does not want to store the picture or the multimedia file that will send into central server; But directly sending to the recipient, system of the present invention also can provide point-to-point send mode.

P-2-P technology comes from LAN-sharing, has become the irreplaceable a kind of technological means of communication on the internet at present, and its target is to change the traditional approach of people through the transit server swap file, reaches the purpose of free exchange resource.IBM (IBM) has descended as giving a definition for point-to-point: system is made up of the computer of some interconnected cooperations; And have one of following characteristic at least: system exists with ... the active cooperation of marginalisation (non-central type server) equipment, and each member directly is benefited from other members rather than from the participation of server; The member plays the part of the role of server and client simultaneously in the system; The user of system applies can recognize existence each other, constitutes a virtual or actual colony.Point to point network is the basis of the Internet overall architecture, and the most basic ICP/IP protocol in the Internet does not have the notion of client and server, and in communication process, all equipment all is an end of equality.P-2-P technology has changed the position at " content " place, makes it from " " center " trend " edge " that is to say that not C pattern is stored in content on the main server for another example, but exists on all users' the PC.

Under point-to-point situation; If it is simultaneously online with the reception client to send client; The help of server end meeting elder generation is sent client and is connected with the reception client, in case after transmission client and reception client had successfully been set up point-to-point the connection, server end just broke away from connection; Send client and can directly deliver to the desktop that receives client to picture, concrete implementation method is described below.

Refer now to shown in Figure 6, come in the simple illustration, though system of the presentinvention server end 1, sendclient 2, receiveclient 4 and the framework sketch map ofcommunication network 3 when point-to-point method of attachment:

(1) sender's (being user A) is connected toserver end 1 through sendingclient 2, and whether the good friend's (being user B, C) who inquires about oneself is online;

(2) when recipient's (being user B, C) through receivingclient 4 whencommunication network 3 is connected toserver end 1; Sender's (being user A) just can learn that its good friend (being user B, C) is online, and same user B, C can learn that also their good friend user A is also online;

(3) then; When user A will be to user B, when C sends picture or multimedia;Server end 1 will help to set up point-to-point connection between them, in case after point-to-point connection was declared successfully,server end 1 just connected from breaking away between them; This moment, user A did not just pass throughserver end 1 to user B, C transmission picture or multimedia file; But directly send throughcommunication network 3, the picture that the automatic download user A of reception client meeting at user B, C place sends just can be play on the computer desktop background at user B, C after receiving.

Then, explain that with reference to structured flowchart shown in Figure 7 the present invention utilizes the method for computer background remotely playing slide photos and the detailed process of system thereof.

Sender's (being called user A down) is connected toserver end 1 through thelogging request module 21 of sendingclient 2; With identical among first embodiment; The process that needs are verified through theregistration authentication module 11 ofserver end 1; Can just not give unnecessary details at this with reference to shown in the proof procedure of Fig. 3 a among first embodiment.After verifying successfully, sendclient 2 and get final productlogon server end 1 and use other functional module on the server end 1.Then; Sendclient 2 and can adopt UDP (a kind of User Datagram Protocol; Be the communication protocol of TCP/IP standard; Use udp protocol to communicate in the present embodiment, can certainly adopt other agreement to communicate) give out a contract for a project toserver end 1, this UDP has comprised the user profile of userA.Server end 1 can use CSocket::GetPeerName () to obtain sending the IP and the port ofclient 2; But IP that obtains and port should be public network PublicIP and the mapped port NatPort thereof that sends the proxy gateway ofclient 2, and this mapped port is exactly this UDP communication interim Nat port that distribute of the proxy gateway of user A fortransmission client 2.

Server end 1 will send public network IP, mapped port, user profile of client 2 etc. and be saved in the list of data structures of address book 15; Address book 15 is similar with address book 13 functions in first embodiment; It also is to be ranked with horizontal field by user longitudinally to rank the list of data structures that constitutes, and just lists slightly variant, as shown in Figure 8 at horizontal field name; The name of user name list storage registered users longitudinally; Such as user A, user B ..., user N, and horizontal field name is listed in and is divided into fixed field and interim field in the address book 15 of present embodiment, fixed field comprises compositions such as " password, buddy list, blacklists "; After content in its field is stored in address book 15; User login services device end 1 (reaching the standard grade) still is connected (rolling off the production line) with server end 1 disconnection and all can be stored in the address book 15, has only through the user and revises voluntarily just and can change, and interim field then comprises compositions such as " public network IP, mapped port "; Content in its field is not empty during logon server end 1 (rolling off the production line) the user; Have only after the user signs in to server end 1 and (reach the standard grade), will be according to being stored in the interim field after the interim distribution of user's connection situation at that time, in case the user is connected (rolling off the production line) these ephemeral datas with server end 1 disconnection then is cleared.In address book 15, the corresponding user name corresponding of one group of data of each field that is to say the corresponding one group of corresponding field of each user name, and " password " field that for example user A is corresponding is A_x, " buddy list " field is A₁, A₂..., A_n, " blacklist " field is A_H1, A_H2..., A_Hn, corresponding " password " field of party B-subscriber is B_x, " buddy list " field is B₁, B₂..., B_n, " blacklist " field is B_H1, B_H2..., B_Hn, the rest may be inferred, and each user's information and field data all are stored in the list of data structures of address book 15.Like this, behind the transmission client 2 successful logon server ends 1, public network IP, mapped port and user's out of Memory etc. that server end 1 will send client 2 are saved in the respective field title of address book 15, indicate that like this user A reaches the standard grade.

Then;Server end 1 will be positioned at other online user on " buddy list " field ofaddress book 15 of user A (is connected withserver end 1 and user that success is logined) information at once and send back to thetransmission client 2 that user A belongs to; Public network IP and the Nat port etc. that comprise these online users' proxy gateway;Transmission client 2 same these information with the online user are kept in theaddress book 15 and are shown as tabulation, and expects users A makes a choice.

For thereception client 4 at recipient's (calling user B in the following text) place, after loggingrequest module 41 signs in toserver end 1, the process the same withtransmission client 2 arranged equally, just repeat no more at this.

When user A begins to send picture or multimedia when giving the good friend; Elder generation needs the picture or the multimedia file of transmission from thepicture storage element 221 interior selections of the picture/multimedia processing module 22 oftransmission client 2; And then the object of selection transmission; To send to online user B such as from " buddy list " field ofaddress book 15, selecting; Before picture or multimedia being sent, sendclient 2 and at first will send out a checking bag (being the UDP bag here) and give public network IP and Nat port of receivingclient 4, and send out a checking bag (being the UDP bag) immediately toserver end 1 throughpicture uploading unit 222; Let server end 1 go to notify user B place to receiveclient 4,command reception client 4 also sends out a checking bag (UDP bag) for transmission client 2.All preserved port mapping relation separately owing to sendclient 2 withreception client 4 gateway separately, be dealt into the data of gateway, gateway can be transmitted to according to these mapping relations and sendclient 2 and receiveclient 4.

After sendingclient 2 and receiving the checking bag (being the UDP bag) thatclient 4 receives respectively that all the other side sends; Connect and declare successfully;Server end 1 promptly can break away from and send being connected ofclient 2 andreception client 4 at this moment, promptly sendsclient 2 and can directly realize the point-to-point communication that is connected throughcommunication network 3 withreception client 4.

Then; Sendclient 2 and begin to send picture or multimedia file throughpicture uploading unit 222; 4picture download units 432 through picture/multimedia processing module 43 of reception client receive picture or multimedia files and are saved in thepicture storage element 433; After downloading successfully, user B just can be through picture/multimedia playing module 44 playing pictures or multimedia file on the desktop background of local computer.

Above-mentioned P-2-P technology has been used the NAT technology of often using in the network service now, faces the NAT technological overview once down:

The NAT technology can be carried out transparent relay for the partial information of TCP, UDP and ICMP.The concrete implementation method of NAT technology is to realize the multiplexing of IP address through the IP map addresses.The NAT gateway has served as the role of router, and all network packet of going out all must be routed to the NAT gateway; Equally, all are also necessary through the NAT gateway by the network packet that outer net mails to Intranet.The NAT gateway will be mapped as an Internet legal address by the source address of in-house network in the packet that extranets send, and the destination address in the packet of ecto-entad will be replaced to corresponding Intranet IP address through certain rule.The NAT gateway has interior network interface and outer network interface, and wherein outer network interface links to each other with Internet, must have legitimate ip address; Interior network interface then links to each other with Intranet; Can distribute an Intranet IP address of any appointment, generally speaking, this IP address is exactly the default gateway of internal host.A private network 10.*.*.* is for example arranged, and Client A is a computer wherein, and the outer net IP of the gateway of this network (NAT device) is 155.99.25.11 (the IP address of an Intranet is such as 10.0.0.10).If certain process among the Client A (this process creation a UDPSocket; This Socket binds 1234 ports) 1235 ports of wanting to visit outer net main frame 18.181.0.31, so at first NAT can change the former IP address of this packet, changes 155.99.25.11 into; Then NAT can create a Session for this transmission; And distribute a port for this Session, such as 62000, the source port that changes this packet then is 62000.So be that (packet of 10.0.0.1:1234-＞18.181.0.31:1235) has arrived on the Internet and become (155.99.25.11:62000-＞18.181.0.31:1235) originally.After in case NAT has created a Session, NAT can remember 62000 ports corresponding be 1234 ports of 10.0.0.1, the data that send to 62000 ports from 18.181.0.31 later on can be forwarded on the 10.0.0.1 by NAT automatically.(note: be to say that the data that 18.181.0.31 sends to 62000 ports can be forwarded here, other IP sends to the data of this port and will be abandoned by NAT) like this Client A just with Server S1 foundation with one be connected.

This shows; Utilize above-mentioned point-to-point mode to send; The sender can directly select picture or multimedia to send to the recipient from sending client, need not earlier picture or multimedia file be dumped to server end, saves time more; Concerning server end, can be reduced in the load of the recipient that receives client generation when server end is downloaded greatly.Concerning receiving client; Still following server end downloads the same; As long as it is online; Picture will receive the local reception client automatically and play in desktop background automatically, and needs manually to receive and need play by other software pop-up windows unlike other point-to-point transmission file modes such as MSN, because of the present inventionly play automatically in desktop background that need manually to play through pop-up window with other be to possess diverse impression and mode.

In addition, what here will remark additionally is, in the present embodiment; Send client and can exchange, that is to say with the position that receives client, former before this at the user A of transmission client as the sender; As long as the reception client has been installed; It also can receive picture file as the recipient simultaneously, and former before this at the user B of reception client as the recipient, as long as the transmission client has been installed; It also can send picture as the sender simultaneously, and being not limited to certain user can only be sender or recipient's identity.

Sum up

Two embodiment through above-mentioned can see; The present invention has very flexible and changeable load mode; Both can directly carry out the transmission of picture/multimedia file between sender and the recipient, and also can not use server end to transmit and receive picture/multimedia as terminal through setting up point-to-point connection through point-to-point connected mode.When using point-to-point connected mode; Helping to send client through server end earlier connects with the reception client; In case after sending client and the reception client having been set up point-to-point the connection; Server end just breaks away from and connects, and sends client and can directly deliver to the desktop that receives client to picture, on recipient's computer desktop background, plays then; When adopting server end as the load mode of terminal; The sender only needs and server end connects; Picture is sent on the server end, after recipient's reception client detects, just can play from the server end download pictures and in the desktop background of computer automatically.

Conveniently refer to: utilize the present invention; The user selects oneself to want the photo shared after signing in to server end, give the friend of oneself; If it is just in time online to issue those friends; Their computer background can show these pictures or multimedia file automatically in the very short time so, is pleasantly surprised unexpectedly to friends who.Because be to manifest automatically, do not need manually to do any action, no matter old and young, whether specialty or not, as long as watch is exactly.And for the friend of off-line, as long as they open computer, in case online can be downloaded up-to-date picture and multimedia file automatically just receive client, and play in order on the desktop background of this machine.The benefit of on background, playing is exactly need not eject new file window, can not cover other operation windows, so sensation that can influential work; And, still show the icon of program on the Background, do not influence work; So can an edge work, appreciate the photo newly received on one side.

In time refer to: the sender is as long as send new picture at server end, and recipient's reception client just can be inquired about new picture automatically, and in the shortest time, downloads, and the desktop of delivering to the recipient then shows.

And safety refers to: the sender can select to maintain secrecy and send, thereby protects some pictures or multimedia file the person of being received not to preserve arbitrarily or to duplicate, in order to avoid file is propagated by illegal secondary.

The computer background that system and method for the present invention sets off static, single originally conduct; Become an opening and give global digital picture frame window; Open to being ready open friend in the worldwide; Simultaneously also become a digital picture frame to computer, be chosen in that desktop background is play and the function that do not influence computer not only can use the mode of magic lantern to play the content of this locality continuously; Can also play long-range content with the mode of individual or many magic lanterns, background can be described as make full use of its always uncared-for function of performance.The sender sent photo on recipient's the screen in the past immediately, received automatically in real time and play, and possibly bring pleasantly surprised when every day is per to you! At this moment a kind of brand-new intention, brand-new close friend's mode.

Though the present invention describes with reference to current specific embodiment; But those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the present invention; Under the situation that does not break away from spirit of the present invention, also can make the variation or the replacement of various equivalences, therefore, as long as in connotation scope of the present invention in the scope to the variation of the foregoing description, claims that modification all will drop on the application.

About other correlation technique content among the present invention:

1. technological means:

About receiving the picture/multimedia playing module of client, be the interface that adopts among the Windows Shell API: IactiveDesktop, through operation realizes to the correlation function in this interface; About the network transmission function of utilizing communication network to realize, adopted Socket on http protocol to realize; Program is provided with the aspect, adopts the message function response of windows to send the various menu option of client; Carry out when in addition, also adopting multithreading to realize each functional module such as broadcast, download.

2. technical scheme and operation principle:

Receive the realization of client in the windows system, can be divided into scheduling controlling, Network Transmission, program setting, involved technical scheme and the operation principle of picture demonstration substantially, the existing explanation as follows:

(1) scheduling controlling

Scheduling controlling is the control centre of whole reception client operation, mainly adopts correlation techniques such as multithreading, message function, priority to control the mutual scheduling of each module.

Multithreading: realize that broadcast, download, cpu busy percentage and mouse state etc. carry out simultaneously;

The message function: the user all through the message transmission, realizes difference in functionality to the operation of all modules of reception client;

Priority: receive the state that client reads CPU on time, judge thread that whether system have other in operation, have wait for that then other threads are accomplished after, continue to receive the operation of client, avoided phenomenon with other thread preempting resources of system.

(2) Network Transmission

Network Transmission is the part that is in the bottom, and the charge server end exchanges with data with the communication of sending client, receive between the client.System of the present invention can be employed in the major function that Socket on the http protocol realizes transport module.

HTTP is the protocol specification of a maturation, and the agreement that http protocol is concentrated with other ICP/IP protocol is the same, follows CLIENT work.Communication between ICP/IP protocol collection agreement is accomplished through Socket, sends client and sends host, url with the reception client through socket; Accept; Direct visit such as User-Agent is in each functional module on the server end, and each functional module is handled association requests through the parameter that obtains, and sends back to the transmission client and receive client; Flow process is simple like this, and the functional requirement such as change, upgrading of Control Server end flexibly.Good characteristics such as the encapsulation that real-time, the quick calcaneus rete network that implementation has combined socket to communicate by letter is simultaneously served, coupling reach preferable Network Transmission mode combinations.

About data transmission, what system of the present invention had adopted current popular also is the md5 encryption algorithm of comparative maturity, has guaranteed the fail safe of sensitive data in the user profile.

(3) program setting

The program setting is the intermediate level that is in the native system operation, and realization is directly mutual with the user's, and therefore a human, easy-operating interface are arranged is the characteristic of key.The main state value that adopts windows message function to obtain button.

When the reception client applies in the windows system; What the menu that is provided with after its each functional module is decomposed adopted is the employed pallet display menu of present many remote dialogue instruments mode, and the user promptly can realize the custom configuration to whole system as long as start reception client set icon in the windows system.To with the comparison of other communication softwares and the characteristic of self software, its menu can offer the following several kinds of options of user:

1) plays
