Last object

version 3

Last object Pointer

Parameter	Type		Description
This command does not require any parameters
Function result	Pointer		Pointer to the last or current enterable area

Last object returns a pointer to the last or current enterable area, in other words, the object that the cursor is in or has just left. You can use Last object to perform an action on a form area without having to know which object is currently selected. Be sure to test that the object is the correct data type, using Type, before performing an action on it. This command cannot be used with fields in subforms.

Note: This command is to be used only in data entry context, otherwise it will return errors.

The following example is an object method for a button. The object method changes the data in the current object to uppercase. The object must be a text or string data type (type 0 or 24):

   $vp := Last object  ` Save the pointer to the last area 
   If ((Type ($vp->) = Is Alpha field) | (Type($vp->) = Is String var))  ` If it is a string or text area 
      $vp-> := Uppercase ($vp->)  ` Change the area to uppercase 
   End if
