Ways to detect console message during UO calls

Good day,

I am using Unidata 8.2 and building a web frontend to a Unidata application. What I'm trying to figure out is a good method for detecting console message such as Unassigned variables or Unopened file variables during the process. Yes, the messages are being displayed in the COMO, however so is a lot of other information, and I don't want to parse the COMO for console messages. I do want to report the messages back up to the user. Is there an EASY way to detect/trap those console messages? Some SYSTEM variable I can check? 

Thank you for your time,

You can check the LastServerError to get the error messages you mentioned. Here is an example of how I have used it in some of the utiltity programs we supply for UV and UD.

RepMonUoSub = MachineASession.CreateUniSubroutine("REPMON.UO", 2)
RepMonUoSub.SetArg(0, "11")
SubCall2Okay = True

Try
   RepMonUoSub.Call()
Catch ex As UniSubroutineException
   MsgBox("Subroutine REPMON.UO Call Failed (UniSubroutine Exception)" + vbCrLf + "Error Number : " + ex.ErrorCode.ToString + vbCrLf + "Error Message : " + ex.Message, MsgBoxStyle.Critical)
   SubCall2Okay = False
Catch ex As Exception
   MsgBox("Subroutine REPMON.UO Call Failed : " + ex.Message, MsgBoxStyle.Critical)
   SubCall2Okay = False
End Try
If MachineASession.LastServerError <> "" Then
   MsgBox("LastServerError Message was " + MachineASession.LastServerError, MsgBoxStyle.Information)
End If

Thank you, I'll look into that. 

I also have phantoms that are spawning and running as a result of the UO call. I don't think the LastServerError will pick those console messages up. Any ideas of how to catch those as well?

Given that you stated you do not want to parse a COMO output I don't expect you want to parse a _PH_ file output ,which would be the only way to get at those messages. However even if you wanted to do this, it brings up a lot of other questions, such as what provision (if any) have you made in your UO code to check that any spawned phantoms have completed, so that their output can be parsed.

In short there is no simple answer to what you are looking to do with the phantom output.
