I need to be able to pass data from one program to another running on the same system. I dont want to use drop files or UDP. I dont mind using the registry, but the host application needs to be notifed when the registry is updated.
Is there any way I can do this? DDE seems like a viable option, but Im stuffed if I can work out how to use it (manaul? Not worth the paper its printed on!).
I know there is a message which you can post to the system when you update the registry, but I cant remember where I saw it. THis could be another option.
Any help would be REALLY appreciated!!!
