How to call native exe function(visual basic 6.0) From .Net (C#)?

Question

Hi,

We have an exe file produced by visual basic 6.0(unmanaged exe) and a .net exe written with c#.

How can I call a function in unmanaged exe(visual basic) from clr exe?

Thanks.

Answer 1

The only way I can see that working is if the VB6 executable has a COM interface, in which case you should be able to call it from a .Net app.

If you can modify the VB6 application, then the most obvious way is to start VB6 app via command line, pass parameters via command line and get result via exit code or via console output. The vb6 application should be modified to handle the parameters accordingly.
