pass data between 2 apps?

[FlyingBear]

is there as simple way to pass data between 2 apps? it seems DDE support this, but vb.net 2010 seems not support DDE anymore.

in my program, I need launch another exe, then wait the exe finish, and get the export data.

both apps are in the same solution. one method I can think of is: writing the data into a xml file, then load it from the main exe when the second exe is done.

is there an easier way to do this?


thanks

You probably don't actually need inter-process communication. In the main app, call Process.Start to start the second app and create a Process. You can handle the Exited event of that Process and you can then go and get the data the other app saved. The other app can save the data to a file in some pre-arranged location that both apps know about.

If you really want IPC then there are various ways it could be done. One would be to create a TCP connection between the aps but the specifically .NET way is to use Remoting. I've never used it so I can't give you details but there would be plenty of information around if you care to search.
