两个进程的窗口A,B,如何让B产生时候显示在A的上头？
不能用永远置顶的方法。

创建B时将A设为Owner窗口不知道行不行呀

[wetheart]

产生B窗口时调用HWND FindWindow(LPCTSTR lpClassName,LPCTSTR lpWindowName);
找到A窗口的句柄，对A窗口进行处理。

SetParent();

B的App类的InitInstance函数中写成类似这样的

BOOL CBApp::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

	CFrameWnd* pFrame = new CFrameWnd;  
	m_pMainWnd = pFrame; 

	pFrame->Create(NULL, NULL); 
	HWND hWnd = ::FindWindow(NULL, _T("A"));
	if(hWnd)
	{
		::SetParent(pFrame->GetSafeHwnd(), hWnd);
	}

	CBDlg dlg;
	int nResponse = dlg.DoModal();
	if (nResponse == IDOK)
	{
		// TODO: Place code here to handle when the dialog is
		//  dismissed with OK
	}
	else if (nResponse == IDCANCEL)
	{
		// TODO: Place code here to handle when the dialog is
		//  dismissed with Cancel
	}

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