Hi,
Anyone knows if it's possible for an application to send Drag/Drop function to another application?

I'll explain a little further, I'm creating a media player, and when the user dubbleclicks on a music file in explorer the media player will open it and play it, but if there already is an instance of the media player opened, I want the new one to send the file/files the user clicked on through the Drag/Drop function, and then exit.

I've looked into the Win32 API a bit, but I'm so not good with externs etc, Any help appritiated :)

pretty sure you can use 
Extern "Win32"
	Function SendMessage:Int(hWnd:Int, MSG:Int, wParam:Int, lParam:Int) = "SendMessageA@16"

End Extern

for this sort of thing, but you'll have to find the correct variables to use with it.
