MFC，在线程中创建对话框

UINT CTestDlgDlg::ThreadFunc(PVOID pv){

//模态对话框//  CAboutDlg dlg;//  dlg.DoModal();

//非模态对话框  CTestDlgDlg *Testdlg = (CTestDlgDlg*)pv;   CDlgThread *dlg = new CDlgThread; dlg->Create(IDD_DIALOG1); Testdlg->m_MFCThreadHwnd = dlg->m_hWnd; Testdlg->dlg = dlg; dlg->ShowWindow(SW_SHOW);

 //The message loop        MSG msg;    while(GetMessage(&msg,NULL,0,0))    {        TranslateMessage(&msg);        DispatchMessage(&msg);    }

 

 dlg->DestroyWindow(); delete dlg; Testdlg->dlg = NULL; TRACE(_T("释放对话框")); return 0;}void CTestDlgDlg::OnButton4() { // TODO: Add your control notification handler code here m_MFCThreadWnd = AfxBeginThread((AFX_THREADPROC)ThreadFunc,this); }

 

在线程中创建窗口的重点在于，消息循环必须要跟创建窗口在同一线程；但是如果你是在线程中创建的是模态窗口的话，就不需要了
