open an exe file from another exe file coded in vb

i have 2 vb projects that run perfectly. but i have this new requirement. I need to open .exe for project 2 from project 1. both the project have sql server database in back. so they have login/password and customer record开发者_Python百科s that show according to customerid's in both. Now when i click "open project2" button in the first project, it should open the second project with the same customer id as in the first one. how can i do that?

The Shell command in VB 6 will open an exe, but I agree with Scott. You might want to separate that form into a common DLL that you can load at runtime from your other app.
