The following sample code shows how to destroy the object associated with the OBJECTID of the WP_SAMPLE class, registered earlier:

#define INCL_WINWORKPLACE
#include "os2.h"

HOBJECT hObj;
BOOL    rc;

{
  hobj = WinQueryObject( "<WP_SAMPLE>" );
  if (hObj != NULLHANDLE)
  {
    /* WinQueryObject of WP_SAMPLE was successful */
    rc = WinDestroyObject(hObj);
    if (rc)
      /* hObj was successfully destroyed */
    else
      /* WinDestroyObject failed */
  }
  else
  {
    /* WinQueryObject failed */
    return;
  }
}
