Using MFC with windows form
-
I create a windows form application named p2pport. and I want to use the Message Map of MFC. so I use MFC with shared DLL and include afxwin.h. But When I compile it, it says that Debug Assertion Failed File : dbgheap.c line 144 Expression : _CrtIsValidHeapPointer(pUserData) I find it is because of the afxwin.h. I google it and found that it is a bug that was reported to MSDN. http://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=99715[^] I use that method to replace the main function and put #include in stdfax.h file. My original code is
#include "stdafx.h" #include "Dlg.h" using namespace p2pport; [STAThreadAttribute] int main(void)//array ^args) { // Enabling Windows XP visual effects before any controls are created Application::EnableVisualStyles(); Application::SetCompatibleTextRenderingDefault(false); // Create the main window and run it Application::Run(gcnew Dlg()); //Application::Run(gcnew Form2()); CMFCApp k; return 0; }And I modify it.#include "stdafx.h" #include "Dlg.h" using namespace p2pport; [STAThreadAttribute] class CMFCApp : public CWinApp { public: virtual BOOL InitInstance() { // Enabling Windows XP visual effects before any controls are created Application::EnableVisualStyles(); Application::SetCompatibleTextRenderingDefault(false); // Create the main window and run it //Application::Run(gcnew Dlg()); return FALSE; } }theApp;But it comes the error. error C3115: 'System::STAThreadAttribute': this attribute is not allowed on 'theApp' I delete the[STAThreadAttribute]. It comes another two errors. error LNK2001: unresolved external symbol _main fatal error LNK1120: 1 unresolved externals I dont know how to solve it. I stuck it all day. Can anybody help me to solve the problem. Appreciate for ur reply Thx. Jane -
