Comments

The DTWAIN_EnableIndicator function turns on or off the Source's progress indicator when acquiring images.  If bEnable is TRUE, the progress indicator is turned on, else it is turned off.  This function should be called before acquiring any images.

For acquisitions that do not require the Source's user interface, the progress indicator should also be disabled by the application.  If not, the progress indicator may still be visible, even though the Source's user interface has been hidden or disabled.

Note that the Source may not support a progress indicator or support an application from turning off the progress indicator.  To check if the Source supports turning off the progress indicator, call DTWAIN_IsIndicatorSupported.

TWAIN State Transitions

The Source must be in State 4 or higher
