Hi,

The TraceLog files have binary data and have a set structure to them; if
you are able to read it on Win2k then you should not have any problems
reading it on WinXP or Win2k3 (unless ofcourse the file is corrupted).

To come to the problem:
a. I dont believe this is related to the scripting runtime dll or WMI.
b. I was NOT able to reproduce the behavior here using the Trace Log Reader
sample available with EIF. Can you try using it on WinXP to read the
remote trace log file?
c. Are there any exceptions being reported? (in the Event Log ?)
d. Does your AppendEntry() method write to a file/console? How are you
determining that the WinXP is not able to display the records correctly.
e. Does it happen with other WinXP machines?
f. Can you explain what you meant by " if the file is not the one being
logged to I can read it with the XP Pro box".

Let us know...
Thx

Barath

>I am having a problem that I can not read the current log file from a
remote computer using the XP Pro operating system. I have run the test
suggested by Mike Hayton in the thread "EIF - The preffered event sink in a
distributed environment" and came up with one difference. The version of
my sccrun.dll is 5.6.0.6626 . The log files are being created on a
Win2K3 server. I can open these files using a Win2K Server and a box
running Win2K Pro but not on a box using XP Pro. I have not taken the
step of clearing ADAP like Alf. What do I need to do to get this file to
return the results in it back to the XP Pro box.

The code I use to read the log files is as follows.

//----------- Calling the Enterprise Instrumentation APIs
------------------------------------

private void ReadTraceLog(string fileName)
{
        // open and read the file of the passed fileName.
        // if exception happens during open, let it be thrown.
        TraceLogReader.ReadLogFile(fileName, new
EventReadCallback(this.MyEventReadCallback));
}

private bool MyEventReadCallback(EventContainer container)
{
        // for each record read, turn it into an EventEntry
        // (catching any deserialization exceptions) and call AppendEventEntry()
        // with the event entry.
        EventEntry entry = null;
        try
        {
                EventEntrySerializer serializer = new EventEntrySerializer();
                container.Evaluate(serializer);
                entry = serializer.GetEventEntry();
        }
        catch (Exception e)
        {
                entry = new EventEntry();
                entry.Add(ErrorMessage, e.Message);
                entry.Type = null;
        }
        AppendEventEntry(entry);

        // return true if we want to continue reading.
        return (reading && !shutdown);
}

I get to the place where the TraceLogReader makes the call to read the file
and passes the delegate but it never calls back to it. And then the
display shows no records in the file. The file does have the entries in it
becuase it can be opened on a Win2k box to show that.

All security has been set up to allow this across the network.

One last note is that if the file is not the one being logged to I can read
it with the XP Pro box.

Thanks
Crockett
