I don't know if this is a bug but it's certainly something that worked before 4.40

Line 6701: Bad parameter type, number expected instead of string.

That's from a CallCFunction() call.

I see this in the changelog : " Changed: Call(C)Function(Fast) parameters have been changed from 'Any' to 'Integer'."\

What does that mean exactly? The documentation is exactly the same as far as I can tell. The function(s) I'm calling needs a string parameter passed in.

use @mystring.s or @"bla"
or better, don't use callfunction, use prototypes

I try not to fix things that aren't (or weren't) broken

Guess I'll be switching. Kind of wish this was documented!

Did you try pointers with it?

Pointers it was!

Many of us posted this as a bug or a question, myself included It was in the list of changes IIRC though...

Thomas, I use the @-thing....why is better to use prototypes? Any problems with the @-thing?

OK, but couldn't our PB compiler make it for us ? I mean when we pass a string to a DLL, it passes the pointer instead (like it has been so far). It's BASIC after all. Maybe, are there any other problems ?

Because I think then you can call the function name directly in your code once you set up the prototype correctly, instead of CallFunctionFast() etc, etc.
