Using the OBJECT SET VISIBLE command allows objects on a form to be visible/invisible. The following code below takes in an pointer to a array for selective objects names to control the visibility:

// ------------------------------------------------------------------ // Name: set_objects_visibility // Description: Takes a pointer to an array to set the visiblity of // objects. // // Input Parameters: // $1 (POINTER) - Pointer to an array of object names (in text) // $2 (BOOLEAN) - True - Visible, False - Not Visible // ------------------------------------------------------------------ C_LONGINT($i) C_POINTER($1;$arr) C_BOOLEAN($2;$choice) $arr:=$1 $choice:=$2 if (Count parameters>1)    For ($i;1;Size of array($arr->))       OBJECT SET VISIBLE(*;$arr->{$i};$choice)    End for End if

Here is a example to control visibility of a "Button" and "Combo Box" where the array entry is the "Object Name" :

ARRAY TEXT(obj_names;2) obj_names{1}:="Button" obj_names{2}:="Combo Box" set_objects_visibility (->obj_names;False)
