Question

This is my first post. Please forgive me for asking a basic question as I’m new to programming.

I have following code and it just didn’t compile

 Module Module1

     Public Sub Test

         dim a as New TestClass() 
         dim b as string
         b = a.ReturnString()

     End Sub

 End Module

Public Class TestClass

     Public Function ReturnString() as string
         Return "Hello World"
     End Function
End Class

EDIT: problem solved

Lesson: Need to instantiate class before using it, many thanks to Gens and all of you!

Answer 1

Your TestClass need to be instantiated before use. To instantiate a class, use new keyword before the class name

dim a as new TestClass()

dim b as string

b = a.ReturnString()
