I've got an app written in Visual Studio C++ that deals with excel lines of data and presents it in a Form.

I now need to print the data. A while back I wrote this app in VBA and printing was a simple task of calling UserForm1.Print

How can I get my C++ app to call up this UserForm1 and call that UserForm1.Print command?

Once I get the connection between these two entities I can send the data I want printed and let VBA do the print work.

How does my C++ talk to my Excel VBA?

Thanks for anything
