Provide Minimize/Maximize Buttons in VBA Forms (Macro)

By | October 19, 2013

Most of the developers came across this particular limitation i.e. minimize and maximize buttons in VBA forms.

These buttons are by default available in Visual Basic forms i.e.; in design view of form we can locate appropriate properties for these buttons.  But while designing VBA forms these properties are not available and the buttons doesn’t appear on the form.Start_UserformNew Stuff: How to set default reserved quantity in Sage 300 ERP

In order to add these missing buttons kindly follow below code snippets.

Step 1: Variable declaration in the main module file.
Public Const WS_MINIMIZEBOX = &H20000
Public Const WS_MAXIMIZEBOX = &H10000
Public Const SWP_FRAMECHANGED = &H20
Public Const SWP_NOMOVE = &H2
Public Const SWP_NOSIZE = &H1
Public Const GWL_STYLE = (-16)
Public Declare Function GetActiveWindow Lib “user32.dll” () As Long
Public Declare Function GetWindowLong Lib “user32” _
Alias “GetWindowLongA” _
(ByVal hwnd As Long, _
ByVal nIndex As Long) As Long
Public Declare Function SetWindowLong Lib “user32” _
Alias “SetWindowLongA” _
(ByVal hwnd As Long, _
ByVal nIndex As Long, _
ByVal dwNewLong As Long) As Long

Public 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

Now let’s add the buttons to the form.

Step 2: Define method “AppAddMinimizeMaximizeButton” in the user form.
Private Sub AppAddMinimizeMaximizeButton(p_str_Minimize_Maximize_Box As String)
Dim hwnd As Long
hwnd = GetActiveWindow
Call SetWindowLong(hwnd, GWL_STYLE, _
GetWindowLong(hwnd, GWL_STYLE) Or _
Call SetWindowPos(hwnd, 0, 0, 0, 0, 0, _
End Sub

Step 3: On form activation; call the method to add the buttons to the user form:
Private Sub UserForm_Activate()
AppAddMinimizeMaximizeButton WS_MINIMIZEBOX    AppAddMinimizeMaximizeButton WS_MAXIMIZEBOX
End Sub
After execution you can notice the buttons has been added to the form.


Using above mentioned instructions minimize/maximize buttons can be added VBA forms (macro).
