hi I was just wondering something about be able to shell your program and make it start with a certain function, for example when you shell Regsvr32 and put the space and \u at the end to say unregister a active x control, is there a way to make your vb app shell so that a particular functin is executed? the reason I ask this is I want to add a file asociation to my app, but if I just put the path to my app it will just open my app as it would if they just doubled clicked the exe and not open the file with it.
