memory usage

when i check it on the task manager's procesess its too high

tnx

big images, are the main thing for huge memory usage... thats all I know of

.NET apps don't actually use as much memory as the Task Manager implies. Don't retain references to objects you're no longer using is basically the only way to reduce memory usage. If you've written your app properly then you are only using as much memory as you need. There is information on MSDN about resource management if you want to get into the nitty gritty.
