    <p><strong>UPDATE</strong></p> <p>Thanks to feedback below I was able to home in on ADPlus.vbs, which is part of the debugging tools for Windows.</p> <p>Don't forget to set up _NT_SYMBOL_PATH before you run it.</p> <p>Using this we've been able to see much more clearly in to the application with far greater clarity than we ever have using the regular dumps produced via Windows when the application crashes.</p> <p>Many thanks to all for the responses.</p> <p><strong>ORIGINAL QUESTION</strong></p> <p>We have an server application written in Visual C++ that some times (relatively rarely) crashes on customer sites. We haven't been able to understand why this happens based on looking at our own log files so the next step is to start looking at crash dumps.</p> <p>We've just purposefully put a bug in to our app (a null pointer) so that we can generate a crash dump and verify that the dumps produced are valuable, but thus far I can't make head or tail of what i'm seeing.</p> <p>I think my first question is whether i've even got WinDbg set up correctly (the other developer here is loading the dump in to Visual Studio 2010 and seeing the same errors so i'm assuming it's fine, or we're both wrong :) ) - and then next question is, how do I understand what it's telling me.</p> <p>The main confusion is that the dump seems to be telling me it has reached a break point, which seems odd to me since there was no debugger connected.</p> <p>The app was running on a Windows Server 2003 system when it crashed. I believe I have pointed WinDbg at the PDB file for the DLL and EXE correctly.</p> <pre><code>FAULTING_IP: ntdll!DbgBreakPoint+0 7c81a3e1 cc int 3 EXCEPTION_RECORD: ffffffff -- (.exr 0xffffffffffffffff) ExceptionAddress: 7c81a3e1 (ntdll!DbgBreakPoint) ExceptionCode: 80000003 (Break instruction exception) ExceptionFlags: 00000000 NumberParameters: 3 Parameter[0]: 00000000 Parameter[1]: 8779fdb0 Parameter[2]: 00000003 DEFAULT_BUCKET_ID: STATUS_BREAKPOINT PROCESS_NAME: CallPlusServerLauncher.exe ERROR_CODE: (NTSTATUS) 0x80000003 - {EXCEPTION} Breakpoint A breakpoint has been reached.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
