Can any body tell me how i can do this. Here is the scenario

I am running my order entry system. I am on a VB screen whch has a grid on it also. Users enters the data in the grid and hit apply and it saves the changes. I want to run a seperate utility program so that users before entering apply can click on that stand alone app and it validates the data in the grid from another app. All i need to do is to read the data from another form in another application.

Any help will be greatly appreciated!!!!

Thanks
