Try using the VBA.UserForms object. For example,

Sub AAA()
ShowAnyForm "frmMyForm2"
End Sub

Sub ShowAnyForm(FormName As String)
Dim N As Long
With VBA.UserForms
N = .Count
.Add FormName
.Item(N).Show
End With
End Sub

hello !

I have a userform for which I want to programmatically set/change
properties in a function before displaying it.

Instead of hardcoding the form's name at many places in the function, I'd
like to assign it to a form object and use this object in my function.

How can I do it ?

I tried :

Dim frm AS MSForms.UserForm
Set frm = frmActualFormName

Using this syntax, I can access and edit form's controls, but when the
program reaches :
frm.Show

I get an error 438 : Object doesn't support this property or method.

Why ?

Thanks.
