Error

I have a dll written in C.

When I use one of the functions I get the following error:

ByRef argument Type Mismatch

and it highlights a variable that I'm passing.

The variable is of a User Type that I declare before using.

Any ideas??

thanks,

Try

Byval Param as Variant

I can't because it's a user defined type variable.

Its very hard to guess the problem without seeing some of your code.

;)

Thanks,

I figured it out. It had to do that the type was declared twice.
