Parameters

|
Symbology |
The variable that specifies the symbology type. Use a value of WLNOSYMBOLOGY if you do not want a barcode symbology returned by the widget. |
Remarks
The default return type is WLWIDGETTYPE. To process user input based on the return type (command key, widget input, scanned input, etc.), use the LastInputType Method.
The default value returned by a widget is different for different widget types. Use the RFInput Method or GetEvent Method to return the value of the widget.
Use a value of zero (0) for the Index parameter for all widgets unless the widget has multiple return types. Currently, only the checkbox widget has multiple return types. The possible values for the checkbox widget are:
0 - CHECKED
