Explorer Integration in the Context Menu but using the already running instance
问题 I want to check for the existence and if it doesn't exist add some actions in the Explorer's right click (context) menu. Besides of the above requirement (for which one can find easily solutions on web) I want to add one more: Suppose that I register the following commands: "Command #1" - triggers 'C:\MyProg.exe /cmd1' "Command #2" - triggers 'C:\MyProg.exe /cmd2' ... (aso.) How do I check if there is already a running instance of MyProg.exe and passing it the appropriate command/command line
