Hi, say I have an app running in the background from startup. Now say I added an option to the explorer context menu to launch the app by right-clicking a file (how would one pass that filename in as a parameter by the way?), I would only want one instance of my application open.
So in the new one that opens, is there a way for it to tell the already open one to call a specific function? And send that filename to it?
I really hope that was clear enough
