    <p><strike> whenever I call a <code>GC.Collect()</code> or <code>GC.GetTotalAmountOfMemory(true)</code> the whole program just hangs. Now, I know what you gonna say: Don't call <code>GC.Collect()</code> the GC takes care of itself. The problem is: It doesn't in my case, something hangs around in memory and the GC can't get rid of it.</p> <p>I've no idea what it could be (project is big/old). I hope someone knows how to obtain informations about what the GC tries to do (and obviously can't do) so that I can search for the problem or if something like a memory profiler could be of any help here (I've ANTS currently installed) and what I should search for.</p> <p>*edit something I totally forgot: Sometimes when I call one of the two methods of GC, the memory usage increases by ~10 kilobytes / second</p> <p>*edit2 I've to correct myself: GC.Collect() runs just fine. Only GC.GetTotalMemory(true) hangs. GC.GetTotalMemory(false) works just fine, too.</p> <p>*edit3 and yup as some of you already said: It seems to be a finalizer somewhere. When I run WaitForPendingFinalizers() it just sits there, doing nothing aswell. </strike></p> <p>ok, now I'm completely confused: When I enter a <code>GC.GetTotalMemor(true)</code> or a <code>GC.WaitForPendingFinalizers()</code> into the immediate window of Visual Studio after I paused the debugger, the program hangs (<em>that's what I did the whole time...I feel stupid now</em>). When I add it to my usual source code and compile it, it works just fine.</p> <p>Sorry about the whole fuzz, seems the memoryleak has another cause. </p>

    1. COIf you have a memory leak, calling `GC.Collect()` won't help

    2. COGC.Collect() or GetTotalAmountOfMemory() can only hang if the heap is corrupted. Look for bad pinvoke or COM code.

    3. COIs it hanging, or simply taking a long time?

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.
