At a Wild guess, I'd say ShellExecute with the filename passed as the full parameter string. This is born out by a test app that just shows the param string in a messagebox. -- Dean Earley (dean.earley@icode.co.uk) i-Catcher Development Team iCode Systems

An application can also register a drop target under its "App Paths" key, which will be used in preference to the generic drop handler. -- Jim Barry, Microsoft MVP
