Ok, here is the trick to have min/max dimensions on a resiseable window.

Code: Select all

;
; Max/Min Window size tracking..

Procedure SizeCallback(WindowID, Message, wParam, lParam)
 
  ; Here is the trick. The GETMINMAXINFO must be processed
  ; and filled with min/max values...
  ;
  If Message = #WM_GETMINMAXINFO
    *SizeTracking.MINMAXINFO = lParam
    *SizeTracking\ptMinTrackSize\x = 100
    *SizeTracking\ptMinTrackSize\y = 100
    *SizeTracking\ptMaxTrackSize\x = 600
    *SizeTracking\ptMaxTrackSize\y = 300
  EndIf
  
  ProcedureReturn #PB_ProcessPureBasicEvents
EndProcedure

If OpenWindow(0,10,10,200,200, "Resize me !",#PB_Window_SystemMenu | #PB_Window_SizeGadget)
  SetWindowCallback(@SizeCallback())
       
  Repeat
  Until WaitWindowEvent() = #PB_Event_CloseWindow
EndIf

Sorry Fred, it crashes on my computer.

If I mark 'SetWindowCallback(@SizeCallback())' as text it don't crash, but I suppose this is not really useful for this function.

Windows 98SE is used.

Have a nice day...

This works in Win 98, but Fred's code should work, too:

Code: Select all

;
; Max/Min Window size tracking..
;
Procedure SizeCallback(WindowID, Message, wParam, lParam)
  ; Here is the trick. The GETMINMAXINFO must be processed
  ; and filled with min/max values...
  ;
  If Message = #WM_GETMINMAXINFO
    PokeL(lParam+24, 100)
    PokeL(lParam+28, 100)
    PokeL(lParam+32, 600)
    PokeL(lParam+36, 300)
  EndIf
EndProcedure
If OpenWindow(0,10,10,200,200,#PB_Window_SystemMenu | #PB_Window_SizeGadget, "Resize me !")
  SetWindowCallback(@SizeCallback())
  Repeat
  Until WaitWindowEvent() = #PB_EventCloseWindow
EndIf

Hm, Wavemakers code works fine on my system but I cant find any false in Freds code!? Is it a compiler bug or something internal goes wrong!?!?

Crazy...

Wavemakers modification works fine on my machine.

BTW: Fred you work with WinXP, do you know how to use the zip dll's that comes with it?
Now I have also WinXP at home and I'm testing my templates on this OS (hi Fangles didn't forget you ). Found out that the win internal AboutBox handles the user images on it quite different. In the older Win OS you can work with images of the size 50x240 without problems. Now every image is resized to a square to approximately 32x32.
Have you also found some discrepancies on WinXP?

Have a nice day...

This was a compiler (or better a windows lacks) bug. Worked fine on NT range Windows but failed on Win9x one.. Fixed now.
