HardwareConfig.DisableSelectStacker property

Read-Write property.

Type: Boolean.

Used to disable the Select Stacker on the scanner. If the scanner was Autoconfigured, the value in HasSelectStacker and DisableSelectStacker will be used to determine whether or not the select stacker is present. If the scanner was configured via the Scanner Configuration Dialog or programatically via ConfigureScanner only the value of DisableSelectStacker will be used to determine whether or not the select stacker is present.

This property serves the same function as the Select Stacker check box in the ScanTools Plus Scanner Configuration dialog.

The EZData scanner has the select stacker built in and cannot be disabled; this property must always be False.

The OpScan 3/4/4U scanners do not report the presence of a select stacker. In the absence of any information from the scanner, AutoConfigureScanner assumes that a select stacker is always present and sets the read-only property HardwareConfig.HasSelectStacker to TRUE. It is important to determine whether or not the scanner really has a select stacker, and configure the software accordingly.

ScanTools Plus software has a built-in safety feature that will cause it to ignore your appdef's setting for "Stop On System Error" and always halt on an unknown form whenever the scanner does not have a select stacker. If ScanTools Plus knowledge of your scanner configuration is incorrect and it is told to expect a select stacker when there is not one, this safety measure in ScanTools is turned off and may result in unrecognized sheets being ignored.

If after a call to AutoConfigureScanner you find that DisableSelectStacker = FALSE and HasSelectStacker is TRUE, you must verify that your scanner does indeed have a select stacker. If you do not have prior knowledge of the scanner, you must query the user to obtain this information. If the configuration is incorrect, you must fix it by calling ScanningManager.ConfigureScanner method with the modified HardwareConfig object to update the configuration in ScanTools Plus software.
