LaurelBridge.DCFExamples.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 text editor process to view the log output before exiting.
