Fixed (non sizeable) MDI Child -> NOT POSSIBLE ?

Hi,

Is it possible to create a MDI child that's not sizeable ?

When I set the borderstyle property to Fixed Single, VB changes this run-time to sizeable (try it !). So I came up with this solution:

lResult = GetWindowLong(Me.hWnd, GWL_STYLE)
NwLong = lResult - WS_THICKFRAME
lResult = SetWindowLong(Me.hWnd, GWL_STYLE, NwLong)

(Be sure to make a child window with borderstyle 2 -sizeable !)

This works, but the window redraw rect misses about one pixel, so you get garbage on a small line of the window.

Try this code and resize the MDI Parent from small to large etc. then you'll see the garbage.

Anyone ?

Why don't you just disable the ability to resize by adding code to the form resize event that resets the size of the form back to the original size?

You can do this (add code that detects the resize and sets the form back to the original, but it looks messy).

Have a look at this article:

I tried it and I can set the border to 1 - Fixed Single after the form is set to MDIChild = True.

I'm using VB5 (SP3)

For anyone still interested, I found it myself, it is possible: here's the code to do it...


Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hWnd As Long, ByVal nIndex As Long) As Long
Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hWnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long

Const GWL_STYLE = (-16)
Const WS_MAXIMIZEBOX = &H10000
Const WS_THICKFRAME = &H40000


   wStyle = GetWindowLong(Me.hWnd, GWL_STYLE)
   wStyle = wStyle - WS_MAXIMIZEBOX - WS_THICKFRAME
   SetWindowLong Me.hWnd, GWL_STYLE, wStyle
