Dialog resizing

[newbiepg]

We had created a dialog box that could be resized
now i have to put a check.
If the user tries to reduce the height or width below a
certain size, the dialog should not resize,
like the color palette in adobe pagemaker.
I had created a function that would resize the box back
to the minimum sizes if the user resized it too small
but it creates a flicker that we cant use

Any ideas?

remove WS_THICKFRAME from the dialog's window style.

Or; if you want it to be sizable:

Handle the WM_SIZING event rather then the WM_SIZE event and prevent from being smaller than minimum by adjusting the RECT parameter (lParam). This should prevent the flickering.....

guys thanks
I found a solution using DefWindowProc

this was the solution

LRESULT Classname:: DefWindowProc(UINT message, WPARAMwParam, LPARAM lParam)
{
if(message == WM_getminmaxinfo)
{
MINMAXINFO* minMa = (MINMAXINFO*)lParam;
POINT pt;
pt.x = 100;//some min size for width
pt.y = 100;
minMa->ptMinTrackSize = pt;
}
return CDialog : DefWindowProc(message, wParam,lParam);
}

You can also do the samething by intercepting the WM_GETMINMAXINFO message and implementing an over-riding function. An example is given below:


void CMainFrame::OnGetMinMaxInfo(MINMAXINFO FAR* lpMMI)
{
// TODO: Add your message handler code here and/or call default
lpMMI->ptMinTrackSize.x = 1000;
lpMMI->ptMinTrackSize.y = 800;
CFrameWnd::OnGetMinMaxInfo(lpMMI);
}

Hope this helps.
