Question

创建了一个win32DLL,使用了MFC库，入口处的代码如下 CMyDialog dlg;dlg.DoModal();为什么不显示对话框？

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])
{
int nRetCode = 0;

HMODULE hModule = ::GetModuleHandle(NULL);

if (hModule != NULL)
{
// initialize MFC and print and error on failure
if (!AfxWinInit(hModule, NULL, ::GetCommandLine(), 0))
{
// TODO: change error code to suit your needs
_tprintf(_T("Fatal Error: MFC initialization failed\n"));
nRetCode = 1;
}
else
{
// TODO: code your application's behavior here.
CMyDialog dlg;
dlg.DoModal();
}
}
else
{
// TODO: change error code to suit your needs
_tprintf(_T("Fatal Error: GetModuleHandle failed\n"));
nRetCode = 1;
}

return nRetCode;
}

Answer 1

AFX_MANAGE_STATE(AfxGetStaticModuleState());
CMyDialog dlg;
dlg.DoModal();
加入第一行试试。

Answer 2

连接方式问题？
看看连接器的subsystem选项
