Problem with Server.GetLastError!

[Lars Netzel]

I'm trying to make my own custom error page... but when using
Try

lblErrormessage.Text = Server.GetLastError.Message

lblErrormessage.Text += "<br>" & Server.GetLastError.StackTrace

lblErrormessage.Text += "<br>" & Server.GetLastError.Source

Catch ex As Exception

lblErrormessage.Text = ex.Message

End Try

It goes into the Catch and says "Object reference not set to an instance of
an object." I have debugged alittle and Server is avaliable.. but
GetLastError gives the error..

Do I need to enable something in order to use this?

Hi,
Check whether Server.GetLastError() returns any error object before
accessing its properties.

No I figured it out..

Since you are redirected to another errorpage you loose the GetLatsetError
information, cause you are not on that page anymore.. BUT.. if you in
Global.aspx in Page_error event (where it's still accessible) put
Server.GetLastError in a SESSION variable.. you can get it thru that on the
Errorpage ..
