Hi, I think GetProcAddress can't resolve the function address at your DLL. Can you check your DLL if the function is exported from your DLL (e.g. with Depency Walker from VC, I'm not sure that it is included at the express version). Is your DLL-func exported like extern "C" __declspec(dllexport) int functeste(int i){....} Take also a look to this article and my comment. http://www.codeproject.com/KB/DLL/rsLoadtimeDLL.aspx?fid=29819&select=1269812&tid=1074998[^] HTH Frank

Hi,

SendMessage(hWndTreeView, TVM_SELECTITEM, ActionFlag, hTreeItem);

TVM_.... -> TreeViewMessage HTH

Hi, count the bits: 8-7-6-5-4-3-2-1

if(myByte & 0x4)
{
  //the third bit is '1'
}
else
{
  //the third bit is '0'
}

HTH

Hi, "KEY_WRITE" -> have you administration rights? (because HKLM) What is the return value of GetLastError()? Frank

Hi, CreateFile( "FullFilePath", GENERIC_WRITE, FILE_SHARE_READ, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL); e.g. with FullFilePath = "C:\\MyDir\\MyApp\\debug\\filename.ini" or get the directory with: GetCurrentDirectory(...) or otherwise with: GetModuleFileName(...) + _splitpath(...)

Hi, > Lets say you have a class in your DLL. And this class has a couple of functions that will be exported. Is it nessacery to export the class? To export a class from a dll is only possible from MFC-Class-DLL to MFC-Application. (or Microsoft Specific) To export a class isn't C++ standard. HTH Frank

Hi, Function as a string?? Why? ... but ... You can get the address of a function with FARPROC GetProcAddress(HMODULE hModule, LPCSTR lpProcName); You need the module handle and the name of the function. Example for the function GetMenu from user32.dll typedef HMENU (WINAPI *GETMENU) (HWND); GETMENU FuncGetMenu; HMODULE hUser32Dll; _hUser32Dll = ::LoadLibrary("user32.dll"); if(NULL != hUser32Dll) { FuncGetMenu = (GETMENU)::GetProcAddress(hUser32Dll, "GetMenu"); } if(NULL != FuncGetMenu) { FuncGetMenu(WindowHandle); //HMENU GetMenu(HWND hWnd); } This is an example for dynamic load a dll. --> You need more than only the function name! You also need the function declaration. HTH Frank

Hi, the value from SOCKET_ERROR is -1 if you unplug the network recv will be return 0 Change your code to do { n=recv(client,buff,MAX_BUFF_SIZE,0); if(1 > n) { break; } }while(); HTH Frank

Hi, look at this (Finding crash information using the MAP file): http://www.codeproject.com/debug/mapfile.asp[^] HTH Frank

Hi, I think you don't need an increased priority, you only need a DLL without a deadlock! Or if you havn't a deadlock, you need multithreading. Your problem is, that your application-main-thread can't process the message-loop, if he is running (and blocking) at the DLL. HTH Frank

Hi, you need only one of this libraries. Each of this libraries has the "same" functions, but for other threading and linking! Include path: Version 1: (for the studio) Tools->Options Dialog-Tab: Directories Choose: Library Files and add the directory from the lib Version 2: (only the project) Use Project-->Settings-->Link-->Object\Library module edit box. the correct path for you = ??? -> search for one of this files -> possible results: c:\program files\Microsoft Visual Studio\VC98\Lib c:\program files\Microsoft SDK\lib If you found more than one locations, use the newest versions. (e.g. SDK -> include order) HTH Frank

Hi But winsock.lib (winsock version 1.0) is the old version. The newer version is ws2_32.lib (winsock version 2.0) Frank

Hi, only a (untested) proposal. Have you tried WM_MENUSELECT? This message is (possible) send before WM_INITMENUPOPUP. -> catch the selection before the popupmenu is created HTH Frank

Hi, good question ... a) libc.lib -> single threaded, static link b) libcmt.lib -> multithreaded, static link c) msvcrt.lib -> multithreaded, dynamic link and for debugging versions libcd.lib libcmtd.lib msvcrtd.lib HTH Frank

Hi, why would you connect to another system at function OnAccept()? CMySock::OnAccept() { CMyClientSock *NewClientSock = new CMyClientSock(); Accept( NewClientSock, NULL, NULL ); //--> now the NewClientSock object is connected to the new incoming connection, you don't need construct / connect any object. } HTH Frank

Hi, look at Tools->Options Dialog-Tab: Directories Choose: Library Files and add the directory from the lib HTH Frank

Possible another way .. if(ERROR_SUCCESS != RegOpenKeyEx(...)) { //Get the error code DWORD LastError = GetLastError(); //Get the error code as text (example) TCHAR szBuf[80]; LPVOID lpMsgBuf; FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM, NULL, dw, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPTSTR) &lpMsgBuf, 0, NULL ); sprintf(szBuf, "Error %d: %s", LastError, lpMsgBuf); MessageBox(NULL, szBuf, "Error", MB_OK); LocalFree(lpMsgBuf); } HTH Frank

Hi, only a try ::MessageBox(NULL, "Your text", "Error", MB_OK | MB_ICONERROR| ... ); HTH Frank

Hi, the CListCtrl is in a dialog? Have you create a dialog member function for this CListCtrl (e.g. OnItemchangedMyCListCtrl)? (This is OK at my projects) Or have you the dialog member function "PreTranslateMessage" and look for the LVN_ITEMCHANGED message? Greetings Frank

Hi, I understand, you have an application and want to get the HTML-sourcecode and parse them? Take a look at this: http://www.codeproject.com/miscctrl/simplebrowserformfc.asp I think this is off-topic, but ... To get a website and all links from this site use "Mozilla-FireFox" and the AddOn "downThemAll". Now you need only a "right-mouse-click" and change some options from "downThemAll" and the FireFox will save all website to your harddisk. Mozilla downThemAll
