Syntax Error with MsgBox

Question

This results in a syntax error:

Sub test()
    MsgBox("hello world", vbOKCancel) ' syntax error at this line
    Exit Sub
End Sub

Why?

Answer 1

You're just using the MsgBox method as a Sub. In VB6/VBA a Sub call either doesn't use brackets, or uses the Call keyword.

MsgBox "hello world", vbOKCancel

or

Call MsgBox("hello world", vbOKCancel) 

The brackets come into play when using the method as a function (ie you want the return value)

Dim msgResult

msgResult = MsgBox("hello world", vbOKCancel) 

I would guess that, since you're using vbOKCancel, this is the version you'll end up using to find out what the user clicked.
