Question

VC 在线程内 DoModel一个对话框为什么报错?

Answer 1

要使用MFC线程，即AfxBeginThread创建的线程，这样它会自动帮你初始化一下资源，DoModal就不会保错了

这样它会自动帮你初始化一下资源

能具体说名初始化什么资源吗? 因为我不想用MFC线程, 可以的话我自己应该也可以初始化这些资源的,对吧?

CWinThread* AFXAPI AfxBeginThread(AFX_THREADPROC pfnThreadProc, LPVOID pParam,
int nPriority, UINT nStackSize, DWORD dwCreateFlags,
LPSECURITY_ATTRIBUTES lpSecurityAttrs)
{
#ifndef _MT
pfnThreadProc;
pParam;
nPriority;
nStackSize;
dwCreateFlags;
lpSecurityAttrs;

return NULL;
#else
ASSERT(pfnThreadProc != NULL);

CWinThread* pThread = DEBUG_NEW CWinThread(pfnThreadProc, pParam);
ASSERT_VALID(pThread);

if (!pThread->CreateThread(dwCreateFlags|CREATE_SUSPENDED, nStackSize,
lpSecurityAttrs))
{
pThread->Delete();
return NULL;
}
VERIFY(pThread->SetThreadPriority(nPriority));
if (!(dwCreateFlags & CREATE_SUSPENDED))
VERIFY(pThread->ResumeThread() != (DWORD)-1);

return pThread;
#endif //!_MT)
}

看看MFC源码，自己弄就全部复制
