PowerVista/312 User’s Manual Software Framework 3-5
3.4.1 Print
Print either a result summary or a single result window to the output device selected in Print Setup. The result
summary option is selected in the Configuration / Preferences dialog.
Note: This command operates on the Result Window with focus.
3.4.2 Print Preview
Perform a Print Preview to screen of either a Result Summary or a single Result Window as it would appear on
the output device selected in Print Setup. The Result Summary option is selected in the
Configuration/Preferences dialog. If no printer has been installed via Win95 standard print device selection,
then Print Preview will not function. To run Print Preview, a printer must be installed even if printing will never
be performed from the measurement PC.
Note: This command operates on the Result Window with focus if Result Summaries are not selected.
3.4.3 Print Setup
Print Setup selects the printer for Print and Print Preview, and specifies Windows standard parameters for
printing on an output device.
3.5 Copy - Paste Shots
The copy and paste shots feature built into EasyPower Measure makes the application a flexible data gathering
and organizing tool. Copy Shots and Paste Shots is supplied to copy shots from one database to another, thus
allowing the user to construct databases with only desired measurements.
The EasyPower Measure database has been designed for speed, and thus contains two files for each database.
The first file with extension .dem is the main data holding file. The second file is the pointer file with a .kem
extension. The pointer file contains pointers for fast random access reads of the main data file, and the
description seen in the database view for each shot. The size of the .dem file will always be much larger than its
companion file since it holds the actual snapped data.
Note: Both the .dem and .kem files are essential to define a database. If either one of the pair is deleted,
renamed or modified, then access to the database is impossible.
The database has been designed for speed writing during event capture. For this reason, the database files
cannot have individual shots deleted from within the database. The entire contents of the file can be removed
(see File / Clear) however this is no help in saving only a small portion of data out of a large file. To solve this
problem, shot copy and paste between Acquisition Windows (and thus respective databases) was integrated into
the application.
3.5.1 Copy Shots
Contrary to its command name, Copy Shots does not actually copy data, but retains a list of desired shots that
the user wants to transfer to an alternate database.
The user utilizes the Database View multiple selection list box feature (similar to the file lists in Win95
Explorer) to select shots in an Acquisition Window. Once the shots are selected (highlighted), the user should
issue the Copy Shots command. This command copies the selected list of shots and the source of the shots to
memory for future access.
After selecting (gaining focus by a left click on title bar) the paste acquisition window for the copied shots, the
Paste Shots command should be issued.
Note: There is a 5000 shot maximum limit on the number of shots that can be copied at one time.
