{{DISPLAYTITLE:wpQueryObjectID}}
This method is specific to version 3, or higher, of the OS/2 operating system.

This instance method returns the unique, text object ID that was assigned to the given object when it was installed or changed (with [[wpSetup]]).

==Syntax==
 _wpQueryObjectID(somSelf)

==Parameters==
;''somSelf'' ([[WPObject]] *) - input
:Pointer to the object on which the method is being invoked.
:Points to an object of class [[WPObject]].

==Returns==
;''pszObjectID'' ([[PSZ]]) - returns
:String containing a unique object ID.
:For example, "<WP_DESKTOP>".

==How to Override==
This method is generally not overridden.

== Remarks ==
The install routine uses this variable to ensure that a given object is never re-installed, thereby avoiding duplication of objects.
The object ID is always lost when the object is copied; therefore, only one object ever exists for a given object ID.

==Example Code==
<PRE>
#define INCL_WINWORKPLACE
#include <os2.h>

WPObject *somSelf; /* Pointer to the object on which the method is being invoked. */
PSZ pszObjectID; /* String containing a unique object ID. */

pszObjectID = _wpQueryObjectID(somSelf);
</PRE>
