How to make a dialog box disappear

[Xiangyang Liu ~{AuOrQt~}]

Thanks to all the people who replied to my posting about the window
sizes. Here is a new question:

I have a modal dialog box in my application, when the OK
button is clicked, some intensive calculations will be done which
takes a long time (longer than a minute). The dialog box won't
disappear from the screen until the calculation is finished (even
if I destroy/close it explicitly in my code). I guess it is because
the windows hasn't had a chance to update the screen. I am wondering
if there is a SIMPLE way (like a function call, perhaps) to make the
dialog box disappear from the screen immediately after the OK button
is clicked. The reason I want the dialog box to disappear is that it
looks really bad on the screen (part of window under it will show
after the OK button is clicked). Thanks for any help.

In the OnOK(), do the default OK processing before calling your
calculation routine

<your class>::OnOK()
{
CDialog::OnOK();

<...your calculation code...>
}

Hope this helps

Maybe the calculations should be done after the Dialog procedure EndDialog
has been called? For example, instead of running the calculations from an
OnOK function, calculate once the DoModal() function returns to the
original caller.

Call "UpdateWindow" after the dialog box disappears. This forces a screen
redraw.

In MFC, call the ShowWindow function to hide it in your OK handler:

CMyDialog::OnOK()
{
ShowWindow( SW_HIDE );
// Do processing...
CDialog::OK();
}

Thanks to all the people who responded to my posting. I have tried
all the solutions (UpdateWindow(), ShowWindows(SW_HIDE), etc), but
the problem is still there. Any more help will be appreciated.

Just EndDialog, make your calculation , and..

DialogBox again ( if You need it ). DID You try this?!
