Delegates

[Patrick Long]

I was looking at creating a simple generic sort routine yesterday. The
routine would call a delegate function to do the "what is greater than what"
comparison. Seems simple enough but whenever I have what looks like a
correct delegate signature declared in my form the form will not display in
the IDE and I get an error.

Delegate Function IsGreater(ByVal v1 As Integer, ByVal v2 As Integer) As
Boolean

The error is "unexpected token 'Function' of type 'KW_Function' at line 61
column 14. Expected a 'KW_Sub' token. Unsurprisingly if I change from a
function to a sub it does not error. Is there something wrong with my using
a function?

This is the delegate signature. Could someone try putting this in a windows
application and then try and use it in a form in the IDE.

Thanks

Pat: I'm not sure what the problem is (might the name IsGreater already be
defined elsewhere?), but there's an example of exactly what you're trying to
do at http://www.freevbcode.com/ShowCode.Asp?ID=2150 .

What you're describing sounds like the WinForms Form Editor (specifically
its parser) failing to understand a function delegate. It has similar
problems with some attributes. If you think it is valid code try to compile
it. If I'm right, for the rest of beta 1 you'll have to either not use the
form editor or shift the code to another file.

Hi Patrick,

I believe that is actually a known bug with Beta 1, and has been fixed for
later builds.
