Minimize-Maximize-Resizing-Scrolling in a Userform

[trishgyrl]

Hello.


Is there anyway to enable minimizing, maximizing, resizing, and scrolling with your mouse in a userform?


I noticed that my userform does not have these capabilities and I can't find the properties to enable this functionality.


Any help is greatly appreciated. Thank you!

Have a look at the following link, which contains the necessary code and a sample workbook...

Hope this helps!

andypope's code is good but the controls are not resized along with the userform.

You can use this alternative API-based code to avoid the above mentioned problem.

1- In a Standard Module :

Option Explicit

    [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=If]#If[/URL]  Win64 Then

End Sub
 
Private Sub CreateMenu()
    Call WindowFromAccessibleObject(Ufrm, hwnd)
    lStyle = GetWindowLong(hwnd, GWL_STYLE)
    lStyle = lStyle Or WS_SYSMENU Or WS_MINIMIZEBOX Or WS_MAXIMIZEBOX Or WS_THICKFRAME
    SetWindowLong hwnd, GWL_STYLE, lStyle
    DrawMenuBar hwnd
End Sub

Private Function HasFont(ByVal oCtrl As Control) As Boolean
    Dim oFont As Object
    
    On Error Resume Next
    Set oFont = CallByName(oCtrl, "Font", VbGet)
    HasFont = Not oFont Is Nothing
End Function

2- Code in the UserForm Module :

Option Explicit

Private Sub UserForm_Initialize()
    Call MakeFormResizeable(Me)
End Sub

Private Sub UserForm_Resize()
    Call AdjustSizeOfControls
End Sub

As for adding mouswheel functionality to the userform, you can search this forum as others and myself have posted code here on this topic before.

I've just tested the above code (post#3) on excel 2007 (32bit) and it errors out on the CreateMenu routine because there was a stupid error on the SetWindowLong API delaration... I missed adding the last argument.

So to make the code work with 32bit, anyone using the above code should change the SetWindowLong API declaration form :

[COLOR=#333333]Private Declare Function SetWindowLong Lib "user32" [/COLOR][COLOR=#417394]Alias[/COLOR][COLOR=#333333] "SetWindowLongA" (ByVal hWnd As Long, ByVal nIndex As Long) As Long[/COLOR]

To:

[COLOR=#333333]Private Declare Function SetWindowLong Lib "user32" [/COLOR][COLOR=#417394]Alias[/COLOR][COLOR=#333333] "SetWindowLongA" (ByVal hWnd As Long, ByVal nIndex As Long,[/COLOR][COLOR=#ff0000][B] ByVal dwNewLong As Long[/B][/COLOR][COLOR=#333333]) As Long[/COLOR]
