| Description: | This is a trace engine that records live data to a SQL database. |
| Returns: | Numeric |
Usage:  |
Steady State only. |
| Function Groups: | Database and Data Source |
| Related to: | Trace Viewer Application |
| Format: |
DBTrace(FileName, FriendlyName, MyTrigger) |
| Parameters: |
| FileName |
| Required. The name (not the path or extension) of the database file to which DBTrace should record trace data. |
| FriendlyName |
| Required. A name for this trace instance that is more meaningful to users. |
| MyTrigger |
| Required. The address of the trigger variable that enables this trace. |
| Comments: | DBTrace writes the actual data to the database (using a separate thread) and maintains a live communication buffer with the Trace Viewer. DBTrace provides a number of methods that allow the trace to define the format of the main table, plus additional tables for filtering and conversion of values to user-meaningful names. Information about these methods are available upon request. Do not launch this module, rather, launch the constructor (to create the thread). |
