Tracing in Code Modules

Is there a K2 object in Studio that I can use to log text to either console (when server running in console mode), or k2error.log?

If K2 server is running in console mode, you can simply add a statement like this to the event:

Console.WriteLine("something you want to output");

This statement will write output to the console window at runtime. (My suggestion: add some visual separators (eg. #### or ~~~) to the statement, so that you can easily identify the output in the console window.)

But wait, there's more!
SP4 of K2.net 2003 features the ultra-cool logging framework. You can output custom tracing/logging information to the same logfiles as K2.net uses. Have a look at the K2.net 2003 Logging and Monitoring file that will be installed along with K2.net 2003 SP4's help files.

As an example, you can output to the console/logfiles using the logging framework like so:

K2.ProcessInstance.Logger.LogDebugMessage(messageSOurce,messageString);

or

K2.ProcessInstance.Logger.LogInfoMessage(messageSOurce,messageString);

There's a whole lot of options when it comes to the logging framework - have a look at the helpfile mentioned earlier.
