Thank you Rafke for your tests!!
Yes, it's typecasting (AFAIK), but I don't know how to cast a WPARAM in VB, have to search the web
![Wink](images/smilies/addpack1/wink.gif)
. For cds (I think) I don't need to typecast since it works ok with OpenFile and SetSkin...
For SetVol I have to try a different way, but I don't think it's the correct one :?.. we will see...
I'm "glad" to know that at least the GetStatus command doesn't work also with C++ (it's not my fault :) )
Thak you again :D
