The TraceFile object is used to access the contents of a trace file created from a PowerBuilder application. Unlike the Profiling and TraceTree objects, the TraceFile object does not provide properties and functions to create an analysis model. You use the TraceFile object in conjunction with the TraceActivityNode, TraceBeginEnd, TraceError, TraceESQL, TraceGarbageCollect, TraceLine, TraceObject, TraceRoutine, and TraceUser objects.
The TraceFile object has no events.

The amount of time (in seconds) taken by the collection of trace data. This time has already been accounted for in the timestamps from the trace file, that is, the proper amount of time has been subtracted from the timestamps before they are put in the trace file. The value is NULL if the file is not open. |

NumberOfActivities |
Long |
The number of activities that exist in the trace file. |
