Error Description and Error Number

Hello,

I have an easy question. I have the following error message: The connection is already Open (state=open)

I have a user who receives this error message periodically and I want to trap the error message but in order to do this, I need to know what the error number is associated with this message so that I can correctly trap for the error based on the specific message.

Does anyone know what the error number is, or where I can find that information. I know .net has an error lookup database but it only does a lookup based on the error number, not based on the description.

Any help would be appreciated. Thanks!

where ever in the code it is getting the error message, it can also get the error number.

VB Code:

Try
   'Code Here
Catch ex As Exception
   'Catch the ex.Message and ex.Number
End Try
