How to constitue a method call using string concatation ?

what you are calling will be empty.
it will do nothing.
if you create the stuff before hand you can use a couple combo or list boxes, and when someone clicks a buton, you could do this

If List1.Text = "create" and List2.Text = "storer" Then
Call createstorer
End If

I am not sure if this will work, but you may be able to do this.

Select Case List1.Text & List2.Text
Case "createstorer"
Call createstorer
Case "etc"
call Etc.......
End Select

oh. one more thing, its best to use the Ampersand(&) in string concatation.

because Vb may try to recognize + as an arithmatic operator.
