    <p>You do have to do it the hard way, but it's not really all <strong><em>that</em></strong> hard... Seriously, once you've written the template once, it's a quick copy/paste/modify to match the function name in the Err.Raise statement to the actual function name.</p> <pre><code>Private Function DoSomething(ByVal Arg as String) On Error GoTo Handler Dim ThisVar as String Dim ThatVar as Long ' Code here to implement DoSomething... Exit Function Handler: Err.Raise Err.Number, , "MiscFunctions.DoSomething: " &amp; Err.Description End Function </code></pre> <p>When you have nested calls, this unwinds as each routine hits its Handler and adds its name to the error description. At the top level function, you get a "call stack" showing the list of routines that were called, and the error number and description of the error that actually occurred. It's not perfect, in that you don't get line numbers, but I've found that you don't usually need them to find your way to the problem. (And if you really want line numbers, you can put them in the function and reference them in the Err.Raise statement using the Erl variable. Without line numbers, that just returns 0.)</p> <p>Also, note that within the function itself, you can raise your own errors with the values of interesting variables in the message like so:</p> <pre><code>Err.Raise PCLOADLETTER_ERRNUM, , "PC Load Letter error on Printer """ &amp; PrinterName &amp; """" </code></pre> <p>(The syntax highlighting looks wonky in the preview... I wonder how will it look when posted?)</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.
