thanks for your reply,
The problem is that I don't know how my app is called, I just place the name of it in a table and the main Program do the rest :-)
I cannot include a Clear events because I'll close also the main program and the same is about Clear all release all and so on...moreover I checked the mem status at the beginning and at the very end of my app and it looks identical.
I'll make some experiments with the queryUnload method and i'll let you know .


>I have written a similar application in VFP. It launches other applications into their own processes. The commands mentioned earlier (CLEAR ALL, RELEASE ALL, CLEAR EVENTS) are all good cleanup commands. It sounds like it is in your external (launched) application, not the main launching application, that you need to include these commands so that it cleans itself up.
