my threading causes memory leaks?

well.. hmm.. seems that my program take up about 10 meg ram runnin.. but when i start the threading part.. it jumps to 35..
ok.. so fine.. but when i close that form... (its a different form than the main) the memory is never free'd up.. and i know all the threads exited.. cause it outputs on the console... .. i have it testing in the procedure that the thread runs. for a variable.. and if it see's it. it exits the sub...
and when i reopen that form. it eats up 10-15 more megs.. and so on and so on..
question is
how are you possed to stop threads? or. how do you free the ram the threads were runnin on.
thanks

and when i exit the program.. it actually doesnt close the way.. the form closes.. but its still in memory. till i end it..
thanks

ignore this reply... i found that mistake.. i had a never ending do loop.. :) but still takes up 35 megs ram till the program completly closes.. and continully takes more.. if i close and reopen that window...

well.. ok.. its like this.. my program creates threads.. and then they die.. doesnt keep track of em
just create em and die.. and every time start and stop that part of it.. it constantly adds 15 more megs ram to my process used.. anyone know?
thanks

Although it may look like a memory leak, it probably isn't.
Assuming you use managed code (API's can still cause memory and other leaks) the garbage collector will do its work.
But, you can't say when the garbage collector will free the memory. As soon as memory will become scarce, the garbage collector will jump in, but as long as there is enough memory available, the garbage collector can take it's time before it does it's job.

To force garbage collection at specific moment you can use System.GC.Collect, but it shouldn't be necessary.

In short: as long as you use managed code, you should not need to worry about memory leaks.

managed code?
i'm sorry.. can you explain or direct me to where managed code is explained?
thanks
