Need help with DDT

[Torte Torsten]

'hi folks

'The Dialog, created with the following line of code

DIALOG NEW 0& ,"",80,80,40,30, %WS_THICKFRAME , TO m_hWndSubFormat

'will never be 40x30 but 100x30
'is there any way to make the dialog 40x30 using DDT or
'a window style?

'thx in advance

Torte --

That's a Windows thing, not a DDT problem.

Try manually resizing any Windows application (Notepad, Word, Netscape, whatever) and you will see that Windows enforces a certain minimum size.

I suspect that to create a main window that is smaller than that, you would have to eliminate the title bar.

You may be able to override this limit of Windows by
processing the WM_GETMINMAXINFO message for the Dialog.

I haven't tried it with DDT Dialogs, but I know it works for child
(controls) windows which allow dragging their edges.

Windows sends the WM_GETMINMAXINFO to find out what the Maximum and
Minimum sizes for a Window can be. This is how Windows knows how big
to make a window whn you maximize it. The sames goes for its minimum
size.

DDT or SDK - not important.
I tested WM_GETMINMAXINFO (DDT) under Win2000 - limit is 40 * 27 (pixels !, not units).

With VB i can size a window to the half of the DDT minimum size
in width. The height is both minimum the caption height.

Torte, try this :

      CASE %WM_GETMINMAXINFO
          ' TYPE MINMAXINFO
          '    ptReserved AS POINTAPI
          '    ptMaxSize AS POINTAPI
          '    ptMaxPosition AS POINTAPI
          '    ptMinTrackSize AS POINTAPI
          '    ptMaxTrackSize AS POINTAPI
          ' END TYPE
          ' you should let Windows process it first before you modify the values
          RV&=DefWindowProc(hDlg, Msg, wParam, lParam)
          DIM MM AS MINMAXINFO PTR
          MM=lParam
          @MM.ptMinTrackSize.x=8    ' min set to 8 pixels
          @MM.ptMinTrackSize.y=8    ' min set to 8 pixels
          FUNCTION=0
          EXIT FUNCTION
