I invoked this:

this.browseDialogUnenrolled.ShowDialog();

and got this:

{"Visual Styles-related operation resulted in an error because no visual style is currently active."}



What does it mean and how do I fix it?

Daniel,

We cannot reproduce this problem and are out of ideas as to what is causing this error.  We have trying stopping the Themes service, played with every VisualStyle setting in Visual Studio.  So we know it has to be coming from setting on your machine.  So here are some questions:

  1. Do you have Windows XP Pro installed with Service Pack 2?
  2. Can you reproduce this behavior on another computer?
  3. Do you have any beta video drivers installed?
  4. Do you have a graphics tool running on your machine (i.e. UltraMon)?
  5. Does this fail if you turn on Windows Themes?
  6. Does this fail on both a laptop and desktop computer?

Any other options you can give us would be helpful.  There is nothing we can do until we can reproduce this error.  It is our policy to reproduce an error rather than to attempt to blindly create a fix.

Same problem on other laptop.

In xp I'm not sure that you can turn off themes. It seems to think that my "Windows Classic" is a theme, so maybe themes are enabled.
