I have a userform where I need to have the entire form visible on screen of any computer excel runs on. The size of both the form and the various controls/text in the userform need to be resized.

This is something that I of course never considered as an issue, thinking excel would do this automatically. Instead, it only shows a part of the form depending on which computer I run it on.

Select a formatted range. Double-click the Format Painter (left side of Home tab). You can paste formatting multiple times. Esc to stop
Hello,

You could test code by Tony :

Code:
Option Explicit
'Function to get screen resolution
Private Declare Function GetSystemMetrics32 Lib "user32" Alias "GetSystemMetrics" (ByVal nIndex As Long) As Long 

'Functions to get DPI
Private Declare Function GetDC Lib "user32" (ByVal hwnd As Long) As Long
Private Declare Function GetDeviceCaps Lib "gdi32" (ByVal hDC As Long, ByVal nIndex As Long) As Long
Private Declare Function ReleaseDC Lib "user32" (ByVal hwnd As Long, ByVal hDC As Long) As Long
Private Const LOGPIXELSX = 88  'Pixels/inch in X
Private Const POINTS_PER_INCH As Long = 72 'A point is defined as 1/72 inches

'Return DPI
Public Function PointsPerPixel() As Double
 Dim hDC As Long
 Dim lDotsPerInch As Long

 hDC = GetDC(0)
 lDotsPerInch = GetDeviceCaps(hDC, LOGPIXELSX)
 PointsPerPixel = POINTS_PER_INCH / lDotsPerInch
 ReleaseDC 0, hDC
End Function

'Resize when Userform Initialize
Private Sub UserForm_Initialize()

Dim w As Long, h As Long
    w = GetSystemMetrics32(0) ' Screen Resolution width in points
    h = GetSystemMetrics32(1) ' Screen Resolution height in points
    With Me
        .StartUpPosition = 1
        .Width = w * PointsPerPixel * 0.85 'Userform width= Width in Resolution * DPI * 85% 
        .Height = h * PointsPerPixel * 0.85 'Userform height= Height in Resolution * DPI * 85%
    End With
     
End Sub

Hope this will help

Sorry, but I'm a newbie. Exactly where would you add this code?

I've just decided to add a scrollbar and not get into trying to resize everything. VBA has it's limitations and some things you're just better off designing around without getting overly fancy and running into other problems.

Yes scroll bars allow for more and more controls on a Userform without making the Userform bigger and bigger. And trying to resize every control can require a lot of code from what I have seen.

I also use Multipage Pages which can also have scroll bars if needed. I have maybe 200 controls on one very small Userform by using scroll bars and Multipage Pages.

The following code should allow both the userform and the various controls/text in the userform to be resized along with it.

I'll be the first to tell you that this is totally over my newbie head.

I pasted the code in a new module (using Excel 2016, windows 10 64 bit). And I put the code in my userform, so it's called upon initiation. Doesn't seem to have any effect at all. Of course, I'm handicapped by ignorance so I don't really know how to use it. One of the things that seems curious is in the module I pasted the code in, several lines are highlighted in red.

Private Declare Function WindowFromAccessibleObject Lib "oleacc" (ByVal pacc As IAccessible, phwnd As Long) As Long
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 DrawMenuBar Lib "user32.dll" (ByVal hwnd As Long) As Long
Private Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long

Not sure what this means.

Any general pointers would be much appreciated. Obviously, this is brilliant work and I don't know what I've done to keep it from working as intended. I do appreciate your post.

Ok, I see that red means error and the code won't execute, but it's a moot point because it will never get there.
