LaurelBridge.DCF.Examples.BasicFileLogging Namespace

DICOM Connectivity Framework V3.4
The BasicFileLogging example demonstrates various logging capabilities in DCF.

Public classProgram
Configure simple logging to a file, demonstrate various logging levels and debug logging interfaces.

The debug logging facilities are very useful in providing message dumps of DICOM dimse messages and datasets. The DicomSessionSettings also implements the ILogSettings interface which is used to set logging properties and enable DICOM inputs and outputs to tailor log output on a per-session basis.

This executable will start up a notepad process to view the log output before exiting.

            // Logging before and after setting the debug flags.
            // Note that the debug message with the configuration debug flag was not logged because 
            // the session settings debug flags did not have User1 set.
