More Information about Application.Caller with VBA in Excel

Question

I have been using Application.Caller in a comparison in my code. When a user clicks a commandbutton, I am assuming Application.Caller returns the name of the command button,

Answer 1

As shown in that link, Application.Caller will not always be of String type

You are using StrComp which compares 2 strings. I would recommend using this.

Sub Sample()
    If TypeName(Application.Caller) = "String" Then
        MsgBox StrComp(Application.Caller, "Button1")
    End If
End Sub

And assign this macro to the Form Button which you have on the worksheet.

If you see the example given in the link that I gave earlier, it automatically will be clear to you :)

Select Case TypeName(Application.Caller)
    Case "Range"
        v = Application.Caller.Address
    Case "String"
        v = Application.Caller
    Case "Error"
        v = "Error"
    Case Else
        v = "unknown"
End Select
