Return to an already open application when a user tries to open a new instance

 

This has been a problem that I haven't been able to figure out for sometime. Preventing the second instance is trivial and has many methods, however, bringing back the already running process isn't. I would like to:

  • Minimized: Undo the minimize and bring the running instance to the front.
  • Behind other windows: Bring the application to the front.

    • The language I am using this in is VB.NET and C#.

    I found this code to be useful. It does the detection and optional activation of an existing application:

    If you're using .NET, this seems easier and more straightforward using build-in .NET functionality:

    The Weekly Source Code 31- Single Instance WinForms and Microsoft.VisualBasic.dll

    These link may be of help:

    It has code to detect another instance running, not sure what you can do with it once you've got the instance though.
