In the routine, if the object instantiation causes it to toss an error, catch it in the error-handler part.Various control files will result in different runtime errors, but primarily 426/429 etc are quite common.Knowing what error would be tossed out is a big help, as you can error-check for that error number, butif also knowing that some flag value indicates that it made it past the first few commands but not the 4th command in a procedure, then it had to crap out on that 4th command, so if it was trying to create an instance.

* If the file extension does not have a handler associated with it, add a handler mapping for the extension.
* Verify that the handler associated with the file extension is properly installed and configured.
* Create a tracing rule to track failed requests for this HTTP status code. For more information about creating a tracing rule for failed requests.

This error means that the Web server does not recognize the file extension of the requested resource. A module handler is not configured on the Web server for this extension. If the file extension being denied is required by the Web server, add the appropriate handler for the file extension.

Ok, I got the same error message while trying to open wampserver. I do use vista homepack and in the configuration while installing wampserver, I used explorer.exe as my default browser. But still, as I tend to open localhost, Opera takes over and displays this error message.

I've tried to go to the link mentioned above but I think it's about IIS 7.0 in vista, which is not the problem I'm facing. So, do I need to download some additional handler files, or is it Opera which is creating the trouble.
