I'm trying to write a Web Service that will return several different error codes so the client can handle each error code individually (e.g. err=600 call funcA, err=700 call funcB, etc..).

My code below always returns "500" for the _statusCode (or get_statusCode). Am I doing this wrong? How do I get a Web Service to return custom error codes to the client (javascript)? Any info appreciated. Thanks.

If IsNothing(Membership.GetUser(UserName.ToString.Trim)) Then

Else

objReturnValue = Nothing

End If

Catch ex As Exception When Err.Number = 601 'User Exists

objReturnValue = Nothing

Err.Raise(vbObjectError + 601, "Membership.UserExists", UserName)

objReturnValue = Nothing

End Try

For this to work you need to set the customErrors tag to off in the web.config file.

Thanks for the response. I tried your suggestion but it didn't work. Javascript still returns a 500 error code regardless of the error I raise in my web service:

 -  error {...} Object
+  get_exceptionType {...} Object
+  get_stackTrace {...} Object
+  get_message {...} Object
+  get_statusCode {...} Object
+  get_timedOut {...} Object
  _timedOut false Boolean
  _message "aaa" String
  _stackTrace "   at Microsoft.VisualBasic.ErrObject.Raise(Int32 Number, Object Source, Object Description, Object HelpFile, Object HelpContext)
   at WebService.UserExists(String UserName) in c:\inetpub\wwwroot\App\App_Code\WebService.vb:line 271" String
  _exceptionType "System.Exception" String
  _statusCode 500 Long
+  userContext {...} Object
  methodName "UserExists" String

Are you sure the call is getting to the server? You shouldn’t be getting a 500 error.

mr - Thanks for your response. Yes, in debug mode, I see the web service returning the error code I'm expecting, but when I get back to the Javascript debug window, the return code is 500. Very odd...
