Body
According to MSDN <code>INTERNET_FLAG_RESYNCHRONIZE</code> only "reloads HTTP resources if the resource has been modified since the last time it was downloaded." See <a href="http://msdn.microsoft.com/en-us/library/aa383661%28v=vs.85%29.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/aa383661(v=vs.85).aspx</a>. The 200 returned by <code>HttpQueryInfo()</code> is indeed strange - it should return the real status code. If you can, change the code to do checksum comparison instead of file size comparison. If not, you can look at a few more things: <ul> <li>Disable ETags on the server - see: <a href="http://developer.yahoo.com/performance/rules.html#etags" rel="nofollow">http://developer.yahoo.com/performance/rules.html#etags</a> and <a href="http://support.microsoft.com/?id=922733" rel="nofollow">http://support.microsoft.com/?id=922733</a></li> <li>Add a small extra parameter for your image that ensures that it always downloads like a random number or the file checksum: <code>http://yourserver/image.jpg?r=5452435234</code></li> <li>Disable caching on your client using the <code>INTERNET_FLAG_NO_CACHE_WRITE</code> and <code>INTERNET_FLAG_PRAGMA_NOCACHE</code> in <code>HttpOpenRequest()</code>, and <code>InternetOpenUrl()</code> as described in <a href="http://msdn.microsoft.com/en-us/library/aa383661%28VS.85%29.aspx#INTERNET_FLAG_NO_CACHE_WRITE" rel="nofollow">http://msdn.microsoft.com/en-us/library/aa383661(VS.85).aspx#INTERNET_FLAG_NO_CACHE_WRITE</a>.</li> </ul>

Guidance

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.
