<I already try this method, but this causes an error.
I don't understand what you mean when you say you "tried this method?" What method did you try exactly? As for error, what error did you get? (Perhaps "Compile error: User-defined type not defined"?)
<This is a COM mode DLL and must be refered inside the VB code,
Well, yes, that's true. However, you point that out as if it contradicts the information I've given you. It doesn't.
<and what about the classes, methods and properties, I´m looking for someone that have this documentation or
an sample code to help me in this job.
You might want to read faq222-2244 for more information about getting good answers. If you show us what you've tried, we can help you fix it.
