Name: The name of the component to add. This name can later be used to determine the value entered by the user.
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.
Value: Use this parameter to specify a default value.
Mask: You can specify an edit mask. If you do not specify a mask, no edit mask is applicable.
