how do I exchange data between applications

[bernhard7gruber]

what is the best way to exchange data between two apps ?

 

both of them run on the same machine

 

the task is simply to check wheater the other app is there and if so, to send a list of numbers (ids in a datatable)

 

are there any predefined objects to use, or do i have to code all that stuff with sockets ...

 

I'm thinking of the so hyped SOAP

Interprocess communications are widely done using sockets, and that's most likely your best bet. I'd also use a [msdn=System.Threading.Mutex]mutex[/msdn] for the detection of the receiving application. That'll save you a bit of code.
