// This sample swaps the Default and Move annotation cursors

L_INT LAnnAutomation_GetAutoCursorExample(LAnnAutomation *plAutomation)  
{ 
   L_INT nRet; 
   HCURSOR hCursorMove, hCursorDefault;  
 
   // Get copy of original cursors 
   nRet = plAutomation->GetAutoCursor(ANNAUTOCURSOR_DEFAULT, &hCursorDefault);  
   if(nRet != SUCCESS) 
      return nRet; 
   nRet = plAutomation->GetAutoCursor(ANNAUTOCURSOR_MOVE, &hCursorMove);  
   if(nRet != SUCCESS) 
      return nRet; 
 
   // Change 
   nRet = plAutomation->SetAutoCursor(ANNAUTOCURSOR_DEFAULT, hCursorMove);  
   if(nRet != SUCCESS) 
      return nRet; 
   nRet = plAutomation->SetAutoCursor(ANNAUTOCURSOR_MOVE, hCursorDefault);  
   if(nRet != SUCCESS) 
      return nRet; 
 
   // Cleanup 
   DestroyCursor(hCursorMove);  
   DestroyCursor(hCursorDefault);
