A dll is a dynamic library, a collection of functions and methods. This library kann be linked to an executable (.exe). Windows creates a process for each executable which is started. A process just exists in memory of your OS. A process has an Name and an ID (see task manager). A process executes code which ca reside in a dll.

It's a harmless message being received using the Network Messenger protocol, from the Messenger service. Go to the Services console in Control Panel, Administrative Tools and stop this service, then go to Properties for the service and disable it. The fact that the message is getting through shows you have no firewall - very dangerous - and the fact that the service is enabled indicates you are not running XP SP2, which means that you are not getting Microsoft's latest security updates. If you do not keep up to date and use a firewall, you run serious risk of your computer being compromised by one of the many attacks targetting remote code execution vulnerabilities in Windows and other software on your computer. I recommend that when you reinstall your PC, if your Windows disc is XP SP1 or RTM, UNPLUG FROM THE INTERNET FIRST - physically unplug your modem or router from the phone line or other outgoing connection (saves accidents). Then, after setting up your internet connection, turn ON the XP firewall under the network connection's Properties page, Advanced tab. Only then should you reconnect your internet connection. If you're not sure what version the Windows disc is, it doesn't hurt to do this anyway. If the disk is SP2, it will ask whether you want to enable Automatic Updates during the setup phase. Then go to Control Panel, Internet Options and click Use Blank under Home Page. This ensures that if your default page contains anything dodgy (generally unlikely, but if you have a customised version of IE on your install discs it could do something). As the very next thing you do, before doing anything else, go to Windows Update and download all the updates. Reboot when it tells you, keep doing this until XP SP2 and all the newer updates are installed. I normally opt-in to Microsoft Update so that Office, Visual Studio, SQL Server, etc are all kept up-to-date too. You should ensure you're running up-to-date anti-virus software.

Dear Mark, I really appreciate your response, can you provide me any example or link of winsock Which is used FTP/HTTP/GOPHER?. One thing more, Winsock used any default protocol ? Questions: 1) how the checksum play role in this socket programming.? 2) what is the difference between synchronous and asynchronous socket?

The first letters of my name :) hehehehe Greetings. -------- M.D.V. If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?

sir, I have found the help for that and I am satisfy with this answer but could you guide me where should i write this function? I mean in my Mainthread or the successive function call from the Mainthread.(:doh:) suppose , e.g. for(....) { //thread created from here hThread[i]=(HANDLE ) _beginthreadex(NULL, 0, &Thread, l, 0, &tid); //calling from here ????:confused: } here :confused: ????? where should I call and where should I defined ? unsigned __stdcall Thread(void* pArguments ) { HRESULT hr=NULL; struct argument_list *Lparam= (argument_list *)pArguments ; Package pkg; static int threadID; threadID++; { hr=pkg.EncodeMediaContent(Lparam->pszInFile,Lparam->pszOutFil,Lparam->hwndParent,Lparam->Host,Lparam->UserID,Lparam->InitPackageRequest,Lparam->ScriptFile,Lparam->Port,Lparam->hList,Lparam->_ProtectSet,Lparam->hWndinoutfiledir,Lparam->hwndEncrypt); } if(hr==S_OK) { MessageBox(0,L"thread gone finished" ,L"therad",0); _endthreadex( 0 ); } //or :confused: should I write some where here??? threadID--; return 0; } "Success lies not in the result , But in the efforts !!!!!"

OK, I'm no specialist for WaitObject. And I still do not understand what the code is intended for. But lets start from the beginning. You are creating 3 threads (thread 0 to thread 2) While you have hardcoded the three in the loop index you use the variable ListBoxItemCount in the thread. Looking at your previous answer you say hThread[0] ... hThread[3]. How much is ListBoxItemCount? Because hThread[3] is never initialized. In the way the code is now, it could happen that a task switch occurs in the thread starting loop, after one or two threads where created. In this case the Wait function must fail because not all thread handles in the list are initialized. I understand that this is only a sample code to demonstrate your problem. But I have also doubts that you are going in the right direction. It is very likely, that if you change your design, the code that troubles you will disappear. Greets Leo

just one question. I need your little help. when and how the thread manage? Suppose I have four thread hThread[0] = (HANDLE)_beginthreadex(NULL, 0, &Thread ,&l,NULL, &threadID); hThread[1] = (HANDLE)_beginthreadex(NULL, 0, &Thread ,&l,NULL, &threadID); hThread[2] = (HANDLE)_beginthreadex(NULL, 0, &Thread ,&l,NULL, &threadID); hThread[3] = (HANDLE)_beginthreadex(NULL, 0, &Thread ,&l,NULL, &threadID); and the global function unsigned __stdcall Thread(void* pArguments ) { HRESULT hr=NULL; struct argument_list *Lparam= (argument_list *)pArguments ; Package pkg; threadID++; DWORD dw=WaitForMultipleObjects(ListBoxItemCount,hThread[threadID],TRUE,5000 ); switch (dw) { case WAIT_OBJECT_0 + 0: // a process with h[0] descriptor has exited hr=pkg.EncodeMediaContent(Lparam->pszInFile,Lparam->pszOutFil,Lparam->hwndParent,Lparam->Host,Lparam->UserID,Lparam->InitPackageRequest,Lparam->ScriptFile,Lparam->Port,Lparam->hList,Lparam->_ProtectSet,Lparam->hWndinoutfiledir,Lparam->hwndEncrypt); break; case WAIT_OBJECT_0 + 1: // a process with h[1] descriptor has exited hr=pkg.EncodeMediaContent(Lparam->pszInFile,Lparam->pszOutFil,Lparam->hwndParent,Lparam->Host,Lparam->UserID,Lparam->InitPackageRequest,Lparam->ScriptFile,Lparam->Port,Lparam->hList,Lparam->_ProtectSet,Lparam->hWndinoutfiledir,Lparam->hwndEncrypt); break; case WAIT_OBJECT_0 + 2: // a process with h[2] descriptor has exited hr=pkg.EncodeMediaContent(Lparam->pszInFile,Lparam->pszOutFil,Lparam->hwndParent,Lparam->Host,Lparam->UserID,Lparam->InitPackageRequest,Lparam->ScriptFile,Lparam->Port,Lparam->hList,Lparam->_ProtectSet,Lparam->hWndinoutfiledir,Lparam->hwndEncrypt); break; case WAIT_FAILED: // failure break; case WAIT_TIMEOUT: // no processes exited during 5000ms break; } //printf( "In second thread...\n" ); if(hr==S_OK) { MessageBox(0,L"thread gone finished" ,L"therad",0); _endthreadex( 0 ); } threadID--; return 0; } how can i decide the when which thread come at hThread[], "Success lies not in the result , But in the efforts !!!!!"

Hi!, Ya the application is now ok,But I need your help for continuous proccess how can it possible? Suppose there are five files running in the protection stage. and two three more files are now added in the list and I again give the start command for protection then how these files work with the already running process. I think you can understad the problem. "Success lies not in the result , But in the efforts !!!!!" Amit Mistry - petlad -Gujarat-India

Thank you very much for this guideline. and support. :rose: :rose: if this will not run then I will email you. Thank you once again Dear Mark . "Success lies not in the result , But in the efforts !!!!!" Amit Mistry - petlad -Gujarat-India
