    <p>According to the MSDN documentation for <a href="http://msdn.microsoft.com/en-us/library/ms682396(VS.85).aspx" rel="nofollow noreferrer">CreateEvent</a>,</p> <blockquote> <p>If the function succeeds, the return value is a handle to the event object. If the named event object existed before the function call, the function returns a handle to the existing object and GetLastError returns ERROR_ALREADY_EXISTS.</p> </blockquote> <p>Based on your description, I don't see a problem with what you're doing. There's nothing I see to indicate you're doing something incorrectly. For me, though, I usually create the event once using CreateEvent() and then pass the handle to the thread(s) that I want to be signaled by that event. But there is nothing technically wrong with your approach.</p> <p>You do realize that WaitForMultipleObjects() returns the index of the first signaled handle in the handles array, right? For example, if your named event is the second one in the list, but the first handle is signaled the vast majority of the time (e.g., by a fast-acting thread or a manual reset event that is signaled but never reset), WaitForMultipleObjects() will always return WAIT_OBJECT_0. In other words, your consumer thread will never see the fact that your named event is signaled because the first handle is "always" signaled. If this is the case, put your named event first in the list.</p> <p>You don't happen to have the bWaitAll parameter to WaitForMultipleObjects() set to TRUE, do you? If you do, then all of the handles in the handles array have be signaled before the function returns.</p> <p>Who calls ResetEvent() for your named event? It should be the consumer. It's not accidentally being called by some third-party thread, is it?</p> <p>These are simply some things to double-check. If the event still doesn't behave as you expect, replace the WaitForMultipleObjects() with WaitForSingleObject() to see if your named event properly signals the consumer thread.</p> <p>Hope this helps.</p>

A row detail

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.
