  Hi everyone

  I am using the web browser control in c# 2.0 and am having a little trouble!

  I can easily suppress the javascript errors dialog box (using the appropriate property) but I cannot seem to programmatically determine if there have been any javascript errors.  There must surely be a way to:

  a) Determine if there have been any JS errors after a document has loaded

  b) Traverse the error messages (with line numbers, etc...)

  Does anyone know how to get at this??

  Thanks

  As this would be the active x control rather than the .NET 2.0 Framework, have you had a look at the navigateerror event?

  I have just moved to .net 2.0 and have tried to steer away from wrapping the ActiveX browser component (as it generates HUGE assemblies!) - isn't there a way to get at this event using the flufiness of the framework?

  Thanks

  I thought about the reply above and tried to see if there was a way to dig into the underlying ActiveX without generating the huge wrappers and basically doing away with the fluffy framework implementation.

  It turns out you can, all you need is a sink...!

  This example is so relevant, it could have been written specially for me!  This example shows how to subclass the webbrowser object and attach a sink in order to tack an event handler for the NavigateError event to the underlying ActiveX.  And breathe....!

  This just begs the question, why the hell did M$ not include this in the first place to save the agro of "plumbing"??!!
