Call/Use VB ActiveX Dll in Visual C
I'm having a similar problem. I (finally) generated a wrapper class
following instructions in MSDN article Q194873. This article also has
instructions for using the #import (I haven't tried those
instructions). Here's the URL:
http://support.microsoft.com/support/kb/articles/Q194/8/73.ASP
I'm having trouble passing parameters using the wrapper class.
Many of the VB functions pass string parameters by reference. This
generates a BSTR type parameter in C++. I haven't been successful in
passing parameters to any functions. Any suggestions/samples for
simply populating a BSTR variable and passing it as a parameter?
Thanks,
Brent
