Sending myself an AppleEvent

I have DragReceiveHandler() that I would like to extract the items from and add them to a AppleEvent and send the event to myself. I am unsure of how add to AEDesc list after I retrieve the info with GetFlavorData()

static pascal OSErr MyDragReceiveHandler(WindowPtr theWindow, void *refcon, DragReference theDragRef) {

      ItemReference                   theItem;
      HFSFlavor                         targetFile;
      Size                               theSize;
      OSErr                               err;
      DragAttributes                  dragAttrs;
      short                              itemCount, i;
      ProcessSerialNumber            process;
      AEDesc                              myAddressDesc;
      AEDesc                              dataDesc = { typeNull, NULL };
      AppleEvent                        myAppleEvent;
      AEDesc                              itemDesc = { typeNull, NULL };
      SInt32                              numItems = 0;      
      AppleEvent                        myReply = { typeNull, NULL };
      if ( ! (gApprovedSplashDrag && gInIconSplashBox) ) { err = userCanceledErr; goto bail; };

      if ((err = CountDragItems(theDragRef, &itemCount)) != noErr) goto bail;
      err = GetCurrentProcess(&process);
      if(err = noErr)
            err = AECreateDesc( typeProcessSerialNumber, (Ptr)&process, sizeof(process), &myAddressDesc);
      if(err = noErr)
            err = AECreateAppleEvent( kCoreEventClass, kAEOpenDocuments, &myAddressDesc, kAutoGenerateReturnID, kAnyTransactionID, &myAppleEvent );
      if (err = noErr)
            err = AECreateList( NULL, 0, false, &dataDesc );

      for(i=1; i<=itemCount; i++) {
            if ((err = GetDragItemReferenceNumber(theDragRef, i, &theItem)) == noErr) {
                  if( (GetDragAttributes(theDragRef, &dragAttrs)) == noErr)
                        theSize = sizeof(HFSFlavor);
                        err = GetFlavorData(theDragRef, theItem, flavorTypeHFS, &targetFile, &theSize, 0);
                        //( FSSpec * )*( itemDesc.dataHandle)  = &targetFile.fileSpec;
                        err = AEPutDesc( &dataDesc, i, &itemDesc );
                        AEDisposeDesc( &itemDesc );
      if ( !err )
            err = AEPutParamDesc( &myAppleEvent, keyDirectObject, &dataDesc );
      if ( !err )
            err = AESend( &myAppleEvent, &myReply, kAENoReply + kAEAlwaysInteract + kAECanSwitchLayer, kAENormalPriority, kAEDefaultTimeout, NULL, NULL );
      AEDisposeDesc( &dataDesc );
      AEDisposeDesc( &myAppleEvent );
      AEDisposeDesc( &myReply );
      gInIconSplashBox = (ShowDragHiliteBox(theDragRef, &gSplashDragBox) == noErr);
      return err;

to add to the list, try code like the following (this adds to a list FSSpec for odoc events):

AEDescList docList;

err = AECreateList(nil,0,false,&docList);
if (!err)
      err = AEPutPtr(&docList,1,typeFSS,fssP,sizeof(*fssP));
      if (!err)
            err = AEPutParamDesc (ae,keyDirectObject,&docList);

The AEPutPtr( ) did the trick, thanks again.
