Modeless dialog

I create a modeless dialog in a window,and I overload the function "OnPaint".
At begin it works correctly.However,when I create this dialog ,the dialog abruptly repaint itself endlessly,(I use debug to confirm it) and the cpu's usage is 100%.So I can't do anything!How can I avoid this thing? Thanks a lot!

If you have a dialog that paints continously maybe you need to put a BOOLEAN variable in the class header and then use the boolean variable to make the onpaint function do something or not?

It sounds as if you are calling the Invalidate function within the OnPaint function. Never to that.

Say your dialog modeless is Cwaitdlg then
BOOL CWaitDlg::Create()
{


return CDialog::Create(CWaitDlg::IDD);
}


and
use

waitdlg=new CWaitDlg();
waitdlg->Create();
//do your stuff
delete waitdlg;//kill it


Hope this helps

Did you suppress the Paint object created by default in the OnPaint method?
You must keep it otherwise you will loop like you said.
