Name: The name of the component to add. This name can later be used to determine the value entered by the user.
Query: The query that must be executed for the lookup.
Left, Top, Width: These are three optional parameters that specify the location and width of the object to generate. If these values are not specified, or if you specify the value 0, the form will calculate its most logical position. This will usually be just below the previous object.
Caption: The value of this parameter will be displayed in the label preceding the component.
LookupCaption: The value of this parameter will be displayed as the caption of the look-up screen.
Column: The field name of the column from which the value must be read.
Value: Use this parameter to specify a default value.
FreeInput: Use this parameter to specify whether the user may freely enter values (='True'), or whether the user is required to make a selection from a list of pre-defined values (='False'). If you do not specify a FreeInput value, the value will be set to 'False'.
