FaxMan4 C# library not disposing properly

David Vedvick May 28, 2013 09:18PM EDT

The FaxMan4 C# library is not disposing properly of it's handles on the FaxMan.db file, and the FaxMan4Exec and FaxMan4Done events when the "Dispose" method is called. I believe this is a bug.

I've checked the code and it appears the Faxman .Net component does cleanup in its Dispose method.

Note that the faxman4.exe process will keep the faxman4.db open as well the two event objects are created by the Faxman process as well.
Thanks for your interest in our products and please let us know if you have any questions.

I have come up with a little C# program that instantiates a new FaxMan object and then disposes it and sets it to null and shows the number of handles open by the application afterwards in an indefinite loop - it's currently at 30000+ handles. It leaves an additional three handles to those objects open each iteration. I can e-mail the source to you along with some screen shots of it in action if you want.

- Thanks

Hi David,

Sure if you can send us that sample that would be great, please send it using which is a free file transfer service to and we'll have a look.
