Activate other process - C# / C Sharp

Bsiang Tan

Is there any way to activate or bring the process to front ?
For example, my application will run the windows calculator. After certain
process, I will need to activate the calculator...

I know how to runthe windows calculator..
is Process.Start("calc.exe")

but when I wish to activate the it, I have no idea..
I know there is a function AppActivate( ) in VB..
is there any equivalent function in C# ?
Thank a lot ~

Best regard,
Bsiang

Hi,
You can use such approach:
1. Get Process class instance returned by Process.Start
2. Query Process.MainWindowHandle
3. Call unmanaged Win32 API function "ShowWindow" or "SwitchToThisWindow"
