I don't code in c# and know little about it, but I have a library of code that I'm using. Primarily I code in vb.net. I have added error handling within many of the functions and procedures of the c# library classes. I would like to call a procedure that is in my vb.net form from within my c# code. Can someone please show me how I can do this? The procedure is just a one liner name, no parameters to pass or anything. also, the vb.net form is already open.
