To set a position you must be an wpFolderObject and override the 
wpSetNextIconPos().

To change a currently existent Position you must drag&drop it.

You has no chance to do that outside WPS.
 
 This example shows how you can use the wpInitIconPosData, wpIdentify, 
wpQueryIconPosition, and wpFreeIconPosData 
 methods to find the icon position information for all objects within a folder. 
 In this example, somSelf contains the pointer to 
 the folder being examined. 

     BOOL        bSem;
     WPObject    *Object;
     CHAR        szIdentity[CCHMAXSTRING];
     POINTL      ptl;
     ULONG       ulIndex;
 
     /* Retrieve the icon position information for all objects within
      * the folder    */
     _wpInitIconPosData(somSelf);
 
     /* Find the every object within the folder   */
     bSem = !_wpRequestObjectMutexSem(somSelf,SEM_INDEFINITE_WAIT);
     for (Object = _wpQueryContent(somSelf,NULL,QC_FIRST);
          Object;
          Object = _wpQueryContent(somSelf,Object,QC_NEXT));
     {
 
        /* For each object in the folder, find the position of its icon
         * in an Icon View of the folder   */
        if (_wpIdentify(Object,szIdentity))
        {
           if (_wpQueryIconPosition(somSelf,szIdentity,&ptl,&ulIndex))
           {
              /***** ptl contains the position of the icon for this object 
*****/
           }
        }
     }
     if (bSem)
     {
        _wpReleaseObjectMutexSem(somSelf);
     }
 
     /* Free the icon position data structure    */
     _wpFreeIconPosData(somSelf);
