Re: [twsocket] Memory leaks...
Hi, The TWSocket is on a TDataModule. I am creating the TDataModule and yes I am freeing it. If I was not freeing the TDataModule it would be reported as a leak, along with the other items on the TDataModule. I have not made a test case that just has a TDataModule with a TWSocket. Are you using AQTime?

Re: [twsocket] Memory leaks...
Hello, Sorry for the trouble. I just fixed an error in another part of the program, a call to a driver, having nothing to do with the TWSocket or really anything related to it, and AQTime reports only one leak of 4096 bytes. This one I have no idea what it is. It appears to be from MakeObjectInstance on TApplication.Create. I just switched from SleuthQA to AQtime. AQtime seems pretty good so far. There are many more features and the learning curve is OK. Thanks for all your patience.

Re: [twsocket] Memory leaks...
Hello Mark, When you call connect the function returns immediatily, but the connection happens in background. So it is normal there is memory allocated. Needed memory is not nececarely a leak. --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz Sunday, January 6, 2008, 05:19, zayin wrote: Hello, tcpPort: TWSocket; tcpPort.Connect AQTime is reporting a memory leak after I call connect.

Re: [twsocket] Memory leaks
If the stream behaviour is what you need, I don't see any problem with that. What about memory allocation ? Paul PS: for all who's concerned about memory leaks : I've asked Pierre le Riche (author of FastMM) about memory consumption. The only thing you need to check is the virtual memory.

Re: [twsocket] Memory leaks
If the stream behaviour is what you need, I don't see any problem with that. What about memory allocation ? It is better to keep the object created of course.

Re: [twsocket] Memory leaks
If FastMM doesn't report any leak, then the increase probably result from memory fragmentation. I think FastMM solved the memory-fragmention-problem of the old Delphi memory manager. That's at least my expierence in applications where GetMem/FreeMem is called frequently (several thousands calls per second). FastMM has a much better behaviour than the standard memory allocator prior to D2006. But this doesn't eliminate fragmentation completely. Contribute to the SSL Effort.

Have a look at your global dynamic variables and dynamic variables assigned to forms which have the same timelife as the program. Everything is created in runtime. Basically, I created an object that I can use in a program or in a service. It's easier to test it as a program. Streams and bitmaps are created and freed continuously. (5kb to 2Mb) I never tried it before, but maybe it's possible to reuse a stream instead of free + recreate.

Basically, I created an object that I can use in a program or in a service. It's easier to test it as a program. Streams and bitmaps are created and freed continuously.

I never tried it before, but maybe it's possible to reuse a stream instead of free + recreate. It is always interesting to reuse objects instead of destroying them and recreate a fresh copy.

When you derive a component from an installed component do you have to create packages for design-time installation?
