passing parameters between apps

[DPearce]

I can check if a previous instance of my app is running with App.PrevInstance but how do I pass command line parameters from the second instance to the first without using a timer event and the registry?

Any help would be much apreciated.

You could just write them to a file and access the file on open or close.

Or DDE. Or SendMessage with a custom message.

In other words, there are three ways. Pick one

Thanks, but it sounds even slower than the registry way and I would still need a timer event to check the file. I want a way with no overheads.

I need some way to call a procedure in the first instance or something. Any ideas??

Calling a procedure in the first instance can be done with SendMessage with a custom message. Want an example?

Yes Please,

I have used an API sendmessage thing with Winamp but I have no idea how to code my app so it accepts them. An example would be a great help.
