Mem Usage keeps going up 1

[RMasters]

I am having trouble with an application that I have just completed, when using it I noticed that my machine slows down alot. Investigation reveals that when I dispose of forms, the memory is not being freed up. I set-up a thread to run "gargage collection" every few seconds but the problem remains. How can I rectify this.

Kind regards

Rick

You likely have a memory leak. It's harder to do in .NET, but it's still possible.

What you want to write is "sandwich" code, where you allocate an object, use it (or pass it somewhere else to be used), and then free it by setting it to Nothing. The idea is not to have orphaned references.

You shouldn't do this (set stuff to Nothing) for value types (int, enumerations, DateTime, etc.) For most reference types (classes, strings, interfaces) you don't need to do this, but you can. You absolutely should do this when the object contains an unmanaged resource, like a DB connection, file, socket, etc.
