MFC 下对话框依次显示问题

[bgcelite]

BOOL CAppicationApp::InitInstance()
{
AfxEnableControlContainer();

// Standard initialization
// If you are not using these features and wish to reduce the size
// of your final executable, you should remove from the following
// the specific initialization routines you do not need.

#ifdef _AFXDLL
Enable3dControls(); // Call this when using MFC in a shared DLL
#else
Enable3dControlsStatic(); // Call this when linking to MFC statically
#endif

CAppicationDlg dlg;
m_pMainWnd = &dlg;
int nResponse = dlg.DoModal();

CApp app;
app.DoModal(); //请问一下此处为什么不弹出对话框，谢谢各位了

// Since the dialog has been closed, return FALSE so that we exit the
// application, rather than start the application's message pump.
return FALSE;
}

因为你这个int nResponse = dlg.DoModal();
对话框没有销毁，程序停在这个地方了，你必须先关闭dlg，才会执行下面的

DoModal是模态框。。

[bgcelite]

在dlg.DoModal（）中点击OK后执行app.DoModal(); 但是根本没有弹框程序就退出了

你的CApp是基于对话框的吗，在资源中有添加这个对话框并关联类CApp吗
如果已经做过了你点击OK应该可以弹出

[wltg2001]

CApp app;
app.DoModal(); //请问一下此处为什么不弹出对话框，谢谢各位了
===========
CApp是一个对话框类吗？

正解.模态会阻塞,直到返回
看雪?你懂得...哈哈

	CTempDialog dia;

如果这个CDiaDlg 有弹出的话，不妨将下面的也改成这个试试看，有没有弹出

CDiaDlg dia;
dia.DoModal(); // 当程序执行到这里时为什么没有弹出对话框，谢谢

自己定义个消息,在里面CDiaDlg dia; dia.DoModal();就可以了.
