ALTADataSet.UpdateCalculationProgress

Called when the calculation progress should be updated. Provides ability to customize the calculation progress display.

Syntax

• UpdateCalculationProgress( sender As ALTADataSet , msgx_0 As String, msgx_1 As String, pdone As Double, append_to As Boolean, Prev_increment As Long, Cancel As Boolean )

Parameters

sender: An ALTADataSet object.

msgx_0: The main display label.

msgx_1: The remaining label.

pdone : The percentage to display, in decimal form (0.00 to 0.99).

append_to: If True, append pdone to the current percentage value in the progress display at the rate of Prev_increment, otherwise pdone will replace the value.

Prev_increment: This is the value of the incremental value per progress update if append_to is True. If append_to is False, this value is ignored.

Cancel: This determines if the calculation can be cancelled.

Usage Example

This example demonstrates how to produce a dialog box when the calculation progress should be updated.
