Hi again,

How do you convert LPByte and LPCByte into VB Data Type. I'm using winscard.dll and the functions i need to declare have these two data types which i can't find in MSDN. So if any of you kind knowledgeable souls know how to do this, help v much appreciated.:)

They are pointers, so their VB translation is Long

Thanks for the reply Marco but just double checking. Not all C declarations that are pointers correspond to VB Long data type right? For example LPStr and LPCStr corresponds to passing a VB String Data type ByRef.

 Furthermore i found an article in msdn (http://support.microsoft.com/default...;en-us;q106553) titled "How to write C Dlls and call them from VB" and it said that LPByte corresponds with a String data type. So got me kinda confused.

Again any help or dicussions on this will be much appreciated.

Regards

VB and C store strings in a different way so a conversion is needed to pass them. If you declare the LPByte parameters "ByVal as String" (and probably LPCByte too, though I've never heard of this type) then VB will convert the string to C format and pass a pointer. For all other pointer types use ByRef.
