Parameters

Source

Specifies an open TWAIN Source.

Return Values

If the progress indicator has been enabled, TRUE is returned.  Otherwise FALSE is returned.

Comments

The DTWAIN_IsIndicatorEnabled function takes the open Source Source, and checks to see if the progress indicator has been enabled.  By default, the progress indicator is always enabled.

Note that not all Sources support a progress indicator.  To check if the Source supports a progress indicator, call DTWAIN_IsIndicatorSupported.  To turn on or off the progress indicator, call DTWAIN_EnableIndicator.
