method signitures

[leangross]

hi people,
Is it possible not to assign value to any paramenter/method signatures on a function?

I have some ex. here.

public function Test ( byval a as string, byval b as string, byval c as string)

dim z,x,y as string

z = a
x = b
z = c


end funcion

Can i use the function test without passing the three parameters like, Test("qqqq",,"CCCC") ?

I don't want want to use "optional" on the signature because i want those parameters as nullable

Is there a way i could do that?

Thanks

You probably want to consider overloading here. Do a websearch on overload. But basically, overloading allows you to use the same name for a sub/function and change the parameters. When writing your code, have you seen the built in functions/subs that have the little arrow when you start them? Showing 1 of 2 or 1 of 8 or whatever. These are overloaded.

It would be something like:

Public Function ReturnTest(ByVal a As String, ByVal b As String, ByVal c As String) as String

return a & ", " & b & ", " & c

End Function

Public Function ReturnTest() as String

Return ReturnTest(String.Empty, "f", String.Empty

End Function

This allows you to nullify the values you want and even do something completely different if the values are null. That being said, unless I am mistaken, you can always set your parameters as optional and allow them to be null, or String.Empty in the case of string values. Just a thought.

if mstrmage1768 didnt answer you question, why can you not do this:

    Sub a(Optional ByVal ava As String = Nothing)

    End Sub
