Als je de minmaxbutton van het access-programma zelf wilt beinvloeden, dan heb je misschien iets aan de volgende code:
Private Const GWL_STYLE = (-16)
Private Const WS_CAPTION = &HC00000
Private Const WS_MINIMIZEBOX = &H20000
Private Const WS_MAXIMIZEBOX = &H10000
Private Const WS_SYSMENU = &H80000
Private Const SWP_NOSIZE = &H1
Private Const SWP_NOMOVE = &H2
Private Const SWP_FRAMECHANGED = &H20
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
Private Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal x As Long, ByVal Y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long
Function Buttons(Show As Boolean) As Long
Dim hwnd As Long, nIndex As Long, dwNewLong As Long, dwLong As Long
hwnd = hWndAccessApp
nIndex = GWL_STYLE
Const wFlags = SWP_NOSIZE + SWP_FRAMECHANGED + SWP_NOMOVE
Const FLAGS_COMBI = WS_MINIMIZEBOX Or WS_MAXIMIZEBOX Or WS_SYSMENU
dwLong = GetWindowLong(hwnd, nIndex)
If Show Then
dwNewLong = (dwLong Or FLAGS_COMBI)
Else
dwNewLong = (dwLong And Not FLAGS_COMBI)
End If
Call SetWindowLong(hwnd, nIndex, dwNewLong)
Call SetWindowPos(hwnd, 0&, 0&, 0&, 0&, 0&, wFlags)
End Function
Zet de code in een module en roep de functie Buttons(0) aan. Met Buttons(-1) komen ze weer terug.
.. want Minimize en Close heb ik wel voor elkaar gekregen...
