Its gone.......... Can anyone remind me how to get windows parameters, not paramstr. EG I have a MPEG player, and another app sends a stringlist of filename/s to it I guess using the File types, so that when myapp gets a 'Play' message, it knows to put the file(s) into a Playlist and play the first one, or if its "Enqueue' it puts them all into the stringlist as a que. this is not file drag and drop. Al+ PS if its Windows messages, I cant find the constants for those particular variables as above. --------------------------------------------------------------------------- New Zealand Delphi Users group - Delphi List - [EMAIL PROTECTED] Website: http://www.delphi.org.nz
