how to connect two different windows form application in c#

@OP, you need to elaborate farther and in the best of your ability to express the problem to get a serious response.

So far I can't even understand what you're trying to do? so let me ask you several questions.

a) Do you have two complete separated applications where each application lives in its own process? to make it simple and less technical do you have two .exe files, one for each application? and you want them to communicate or exchange information?

b) Do you have two forms that live in the same application and you want them to communicate? again, to make it simple do you have a single .exe file and two forms?

P.S. You can ask as many questions as you would like and we will do our best to help you but to make it happen you can't write few sentences and expect us to figure all the details by ourselves, you need to make things crystal clear.

I agree with darnold924 to some extent, I'd say let the people that its their area of expertise deal with it unless you want to learn software engineering or something of the sort.
