Wierd Function

Hi there,

I just recently found out that you can leave a colon at the end of a function and still be able to call it without VB crying about it. I then decided to add a variable to and called it and it worked. I just wanted to know if any one had seen this type of syntax for a function?

VB Code:

Option Explicit
 
Private Function TextFunction(): Dim x As String, y As String
    x = "Hello"
    y = "World"
    
    MsgBox x & " " & y
End Function
 
Private Sub Form_Load()
    Call TextFunction
End Sub

Regards,

Everything after the colon is treated as if it was a new line. In other words you can do this if you want but it's poor programming style.

If x = 5 Then: y = 12: End If

Yes. Most people regard it as bad programming because it makes code hard to read. I usually use it for statements which are in the same context:

VB Code:

text1.Text = "": text2.Text = ""

etc..

chem

Ah I see

Thanks man

Regards,

That may have been a bad example, as with VB you can just say

VB Code:

If x = 5 Then y = 12

and leave it at that...

I've always asked myself why VB doesn't allow to intialize a variable after the declaration.

VB Code:

Dim someVariable As Integer: someVariable = 10

Of course, this must be done and it can only be done in a procedure.

I believe .Net allows you to do that.
