How to make 2 program talking together

[supadits]

Dear,
I'm quite new in VB programing. I have a problem about making 2 program talking together. And question about how to make the program that can be executed as command with some parameter.

My first program is UI program but the second one is not. The second on will be executed as command with parameters and these parameter will be send to the first program. (the first program is already running).

Please advice.
Thanks.

For this you will have to start working with call back objects. This can be a bit hairy for the start but it is not that bad.

Have a look at this url: http://www.mvps.org/vbnet/ do a search on Callback objects and read thru the results.

Hope it helps.
