The Data Handler class contains many useful properties that you can use when needed. Some of the most useful properties are briefly described below.
Tip: You should take the time to review the “Data Handler Class” chapter in the VPME 9.1 Technical Reference manual to learn about all the properties and methods available to you in the Data Handler class.
Contains the 20-character string that is placed in Activity, Audit Trail, and Error records to identify the application for which the record was created. By default the application/project prefix is used. The string can be changed through the Options/Environment form in VPM. The string is then stored in the SVPMApplicationDefinition.APD table and passed to the data handler object upon instantiation. Code in the data handler object then puts the string into this property.
Contains the Windows Temporary File Directory path.
Identifies a place to store temporary files.
The application-level Audit Trail setting (whether on (.T.) or off (.F.)) is passed to the data handler object upon instantiation. Code in the data handler object then puts that logical value into this property. That value then causes the Audit Trail functionality in the data handler object’s save and delete functions to be enabled or disabled.
