SUBJECT: NCPAINT doesn't work proberly

[Martin Horst]

Hi,

I'm writing a new dialog class which changes the
visible appearence. Therefore I overwrote the
DefWindowProc to handle the WM_NCPAINT message
by myself. The problem now is that Windows
sometimes do it's own drawing stuff and don't
call my new draw function. This happens when I
move the window or when the window gets inactive.

The program code looks like that:

LRESULT CNCTestDlg::DefWindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
switch (message)
{
case WM_NCPAINT :
{
NcPaint();
return 0;
}
}

return CDialog::DefWindowProc(message, wParam, lParam);
}

The NcPaint() function does the drawing stuff.


Hope someone can help me.

Thanks in advance

hi,
you have to overide other messages which will be generated when you move
dialog box.
