Question

MFC中怎么在应用程序运行时先弹出一个对话框 最好有重要部分的代码

Answer 1

#endif

COpenDatDlg dlg;
m_pMainWnd = &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;

在.cpp中把COpenDatDlg dlg换成你自己的对话框类就可以了

Answer 2

在 app init里面

Answer 3

说明：
在程序的 InitInstance 函数中这样做。
clogoin 程序运行先出现这个窗口
如果(iret == IDOK) 则 domodal主窗口，即m_pMainWnd。
不知道能不能看明白。
BOOL CChargeApp::InitInstance()
{
AfxEnableControlContainer();
CLogoin logoindlg;
int iret = logoindlg.DoModal();
if (iret == IDOK)
{
CChargeDlg dlg;
m_pMainWnd = &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
}
}
return FALSE;
}
