Re: [Quickfix-users] Memory Leak - Please help.

[Malinka R. <ael...@gm...>]

yes, but you don't know when the garbage collector will do it's job and
therefore there is a memory leak until it does happen, which as i've noticed
if you are actually using the system for anything serious it will actually
cause the system to run out of memory and crash your programs before it
actually does collect the garbage, so yes it is good form to call dispose
and yes it will take care of your memory problem, and yes the garbage
collector should take care of that however it like most other things isn't
the final solution and needs a little help and no this is not a quickfix
problem, but a Managed C++ problem in C# ;)
