       CWaitDlg *wDlg = new CWaitDlg(); //CWaitDlg : Class of Dialog IDD_WAITDLG
	wDlg->m_Text = _T("Please Wait...");  // m_text is type edit text of Dialog IDD_WAITDLG
	wDlg->Create(IDD_WAITDLG,this);
	wDlg->CenterWindow();
	wDlg->ShowWindow(SW_NORMAL);
        wDlg->UpdateWindow();

        Sleep(2000); // ****//

       wDlg->DestroyWindow();

When i insert " Sleep(2000) // ****// ", i can not move this dialog wait, after 2s ,i can move this window. And when i connect to hostting,it's empty as "not responding",

i think reason is my program,not win system .

It sure is your program that cause the issue. When you enter Sleep from the GUI thread you effectively prevent the message loop from executing.

Sleep() only example that i insert to test, my code connect to server is in Sleep().

When connect to server ,need a few time to finished (have not Sleep() )->but window dialog can't move and show not normal . It' s the same as Sleep.

Have you any way to create other Dialog Wait ?

[VictorN]

Well, your thread is busy executing what you have in that "Sleep" block, so it has no time for displaying the dialog.
You could however, move this block into another thread...

thanks, i am trying make it by thread ,

Have you considered using SetTimer / OnTimer?

The way I normally do this is to create a modeless dialog box with the "Please Wait" message, and display it before doing the task. Then when the task is finished, terminate the modeless dialog.
