I'm testing my application on a windows 2003 machine. Everything seems to be working okay except for my browse dialog. I receive the following error when I click the Browse.

Any Ideas?

Thanks,
Tim

Didn't make any difference. Still get the error.

Trent, I may have pinpointed the problem for you.  One of the search fields on my browse dialog was a date field. When I removed this field from the search fields list the error went away. When I added it back, the error returned, so it must be specific to the date field.  The date field works fine on XP.

Hopefully it's something simple.

Tim,

I did a google search and this is an issue with the DateTimePicker control it looks like.  The problem is that there is no visual style active on the machine (Themes is just the first step).  The DateTimePicker requires the use of the Visualizer classes in order to render the Combo arrows.

On that same server, try setting the Appearance to the same Theme as Windows XP Blue and see if the error persists.

Yes that worked Trent.

Thanks
