如何在MFC中同时创建两个活动对话框？

Question

I'm trying to run two windows in MFC in the same time - when i run my app. In BOOL CrTestTaskApp::InitInstance() - init function of my app i wrote this:

CrStartDlg sDlg;
sDlg.DoModal();
CrMainDlg dlg;
m_pMainWnd = &dlg;
INT_PTR nResponse = dlg.DoModal();

if (nResponse == IDOK)
{

}
else if (nResponse == IDCANCEL)
{

}

But second dialog apears only after i closed first. And also, if i make Modal() second dialog on BtnClick() first dialog - i cant switch between them.. Active only one...

Help me pls.

Answer 1

You need modeless dialogs, as opposed to modal created by DoModal method.

Modeless dialogs are created with CDialog::Create and act as regular windows, responding to messages dispatched via shared message queue/pump.

• Creating a Modeless Dialog Box with MFC Libraries
• C++ Starting several modeless dialogs using WINAPI ( no MFC )
