start or activate other process

[NiravVyas]

HI..AutomationGuy and Moderators
I am having a bit similar task, which I am not able to get thru. I'll explain..I have two apps A and B, B is kind of a reminder application which runs in the background..but that is not important here, thing is when App B is open, it has a button which takes user to App A, I am doing that using Process.Start("A.exe") all good so far. Problem is I need to make sure that if any other instance of App A is running then I need to jump to that instance. I am able to check for the instance running using Process.GetProcesses() but I am not able to set focus to that running instance. I hope I am clear with my requirement, please ask if any further info is required.

Thanks & Regards,
Nirav Vyas

If you created app B you can make it single instance in project properties, Application tab. How to: Specify Instancing Behavior for an Application (Visual Basic)
If not you can use the AppActivate function and pass it the process.Id or .MainWindowTitle.
