Hi.

I have a C++ Dynamic LIbrary (DLL) and a VB application, I would like communication between the two within a single thread.

I don't know if I can preform this.

Although I can use SendMessage to send to the Visual Basic application I cannot directly reply to this and again I do not know how.

Can you help?

here is an example it is taken from api viewer:

Public Declare Function MAPILogon Lib "MAPI32.DLL" (ByVal UIParam&, ByVal User$, ByVal Password$, ByVal Flags&, ByVal Reserved&, Session&) As Long


so you have to declare the function name Library and the variables you use to send the date and the type of result the function return.

good luck dude
