    <p> I currently debug a multi threaded application, which runs without errors until some functions where called about 2000 times. After that the application stops responding, which I could track down to _beginthreadex failing with an out of memory error. </p> <p> When examining the Application in ProcessExplorer I can see a growing number of thread handles leaked and a growing virtual memory until the error occurs, the private bytes stay low. The leaked threads also call CoInitialize and never call CoUninitialize. </p> <p>What I would like to know is:<br/></p> <ul> <li>What does the Virtual memory represent ?</li> <li>Is the virtual memory related to the leaked thread handles?</li> <li>Does COM or MSXML6 (called by the threads) copy thread handles and how can I Close them?</li> </ul> <p> I hope that my question is clear and doesn't break any roules,it is my first question and english isn't my first language.:-( </p> <p> I forgot to mention, I close the handles returned by _beginthreadex once the threads get terminated, which reduces the number of open handles by about half but does not affect the virtual memory. Additionally before i inserted the CloseHandle call each thread handle shown in ProcessExplorer had a handle count of two for the thread. </p> <p><strong>Edit</strong></p> <p> I fell stupid for not including this before, I know that the threads exit as the number of active threads while debugging with visual studio does not grow. And I do hope that not all of the leaked memory is a result of calls to TerminateThread as they are used in a rather big library and I would prefer not modifying that. </p> <p> To the com part of my question, with !htrace -diff i find thread handles allocated by msxml but not freed after the functioncalls end, could they be related to the leak or will they be Closed at a later time? </p> <p><p> Thanks for all those comments, while the problem is still there they helped me understand it better.</p>

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
