OBJECT Get data source ( {* ;} object ) -> Function result

Parameter	Type	Description
*	Operator	If specified, object is an object name (string) If omitted, object is a field or variable
object	Form object	Object name (if * is specified) or Field or variable (if * is omitted)
Function result	Pointer	Pointer to current data source of object

Description

The OBJECT Get data source command returns the current data source of the object(s) designated by the object and * parameters.

You can define the data source for an object in Design mode using the Property List, or using the OBJECT SET DATA SOURCE command.

Passing the optional * parameter indicates that the object parameter is an object name (string). If you do not pass this parameter, it indicates that the object parameter is a field or variable. In this case, you pass a field or variable reference instead of a string (field or variable object only).

Example

Given a combo box object defined in a form:

You execute the following code:

 $vPtr :=OBJECT Get data source(*;"vCombo")

  // $vPtr contains -> vCombo
