How to create a function that does not return a value?

[Vivek Narayanan]

i want to create a function that utilizes a String and does just about the same thing as a Sub,but does not return a value ,can any one help me out?

A function returns a value, a sub does not. This is another VB disaster, IMO. But, the void return type is a sub. If it's a function, it returns something. Otherwise, there's no difference, AFAIK.

A function that does the same as a sub ??? I would have thought the solution to be obvious; use a sub

I meant a function that does the same as a sub ,but like all functions do,utilizes an Object or a Component but does not return any value

[Vivek Narayanan]

Let me make it clear,its something like this Function str() as String 'code related with str ,which does something to the form,just like code in an event sub RETURN 'I've got nothing to return End Function Say if i choose null as the return value,will the code above it be processed,irrespective of the fact that the function will always return null

[Steven J Jowett]

You could do this :- Function str() as string 'your code here Return Nothing End Function but surely that is the same as :- Sub str() 'your code here End Sub Or is it you what to provide an object for the "function" to work with and change, in which case :- Sub str(ByRef myObject as Object) 'do something to myObject End Sub This would receive the memory address the the object and change it directly, without the need to passing back the result

What you're talking about is still a Sub.

Private Sub SetupDataGridView()
     ' Code to setup your DGV goes here.
End Sub

Seriously, pickup a book on VB.NET for Beginners. This is really basic stuff you're asking about.

I suggest you buy a book and fill in the gaps.
