    <p>I just ran into this problem as I was adding printing to my app. I was using the PrintDialog class and it works great if it is compiled as a 32-bit app, but doesn't even pop up when compiled in 64-bit mode. No error messages, no nothing. The call to ShowDialog just returns immediately. (Note that I am running 64-bit Vista.)</p> <p>I tried using PrintDlg, but that has the same problem. I looked online and found a lot of people we're having similar problems though apparently not everybody who has 64-bit Vista sees this. Anyway, I finally decided to write my own version of PrintDialog (borrowing from code online), but this was a bit tricky (as some of the online code had bugs) and since I never did find a complete example online for this, I thought I would post my solution here.</p> <p>Note, my version leaves a few things out of the dialog, like the "Print range", "Copies", and "Print to file". This should be easy to add but my app didn't need them. I also couldn't figure out what the "Type:" field was displaying so I left it out as well.</p> <p>Here's what the dialog looks like:</p> <p><a href="http://www.geocities.com/deancooper2000/PrintDialog64.jpg" rel="nofollow noreferrer">alt text http://www.geocities.com/deancooper2000/PrintDialog64.jpg</a></p> <p>And here's my code (I've left the designer code out as it should be pretty easy to recreate):</p> <pre><code>using System;

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.
