Performance Issue

[noshaba]

My application is taking too much memory while its running even some forms are closed but still forms are not releasing its utilized memory. all this leads to performance issue.

what method should i adopt so that my form after closing release all its allocated memory. my forms are also using some third party controls like True DBGrid...

plz help me out...

Forms don't need to, and aren't supposed to, release all their memory when they're closed. The .NET Framework provides automatic memory management with a garbage collector that will reclaim memory in a fashion optimal to system usage patterns. You should go to MSDN and read about .NET resource and memory management, but there are two very simple rules that will cover you in 99.99% of situations:

1. If you no longer need an object and it has a Dispose method or equivalent, call that method.

2. If you no longer need a reference to an object and the variable will not, or may not, lose scope for some time then set the variable to Nothing.

That's really all you need.

If you are really worried about it, you can always force the Garbage Collection to happen after a form closes:

GC.Collect();

GC.Collect();

You can but you shouldn't. You shouldn't force garbage collection without a good reason. If you don't know that you have a good reason then you probably don't.
