DISPLAY RECORD
DISPLAY RECORD {( aTable )}
| Parameter | Type | Description | |
|---|---|---|---|
| aTable | Table | → | Table from which to display the current record, or Default table, if omitted |
This command is not thread-safe, it cannot be used in preemptive code.
Description
The DISPLAY RECORD command displays the current record of aTable, using the current input form. The record is displayed only until an event redraws the window. Such an event might be the execution of an ADD RECORD command, returning to an input form, or returning to the menu bar. DISPLAY RECORD does nothing if there is no current record.
DISPLAY RECORD is often used to display custom progress messages. It can also be used to generate a free-running slide show.
If a form method exists, an On Load event will be generated.
WARNING: Do not call DISPLAY RECORD from within a Web connection process, because the command will be executed on the 4D Web server machine and not on the Web browser client machine.
Example
The following example displays a series of records as a slide show:
ALL RECORDS([Demo]) // Select all of the records
FORM SET INPUT([Demo];"Display") // Set the form to use for display
For($vlRecord;1;Records in selection([Demo])) // Loop through all of the records
DISPLAY RECORD([Demo]) // Display a record
DELAY PROCESS(Current process;180) // Pause for 3 seconds
NEXT RECORD([Demo]) // Move to the next record
End for
