This is required when you have a number of comboboxes on a userform and you need to add the same list of items to all comboboxes. Instead of adding items one by one to each combobox, you can just use the below code.
Paste this code on userform_intialize event and run.
Private Sub UserForm_Initialize()
Dim nme As Range
Dim cntrl As Control
Dim CB As ComboBox
For Each cntrl In Me.Controls
If TypeName(cntrl) = "ComboBox" Then
If CB Is Nothing Then
For Each nme In
Sheet1.Range("MyName")
cntrl.AddItem nme.Value
Set CB = cntrl
Next
Else
cntrl.List = CB.List
End If
End If
Next
End Sub
Change highlighted part as per your requirement
