My request is like, i just want to put an alert showing the url of the
uploaded file from where it is uploaded when i click an item in the
list of files.

[Tracy Spratt]

I got my upload working using cookbook techniques and since it is
working I don't have time to figure out exactly what it is doing.

But I do display the selected File name after the user selects from the
File brows dialog box.  Note the line near the end, where I set the
textInput tiFileName.text.  You will need to analyze this code to
underestand what it is doing, I do not remember.

Note, you can NOT display the full path to the file on the local file
system, for security reasons.

Tracy

  // Called when a file is selected
  private function onSelectFile(event:Event):void {
    this.enabled = true;
    var arrFoundList:Array = new Array();
    if (bMultipleSelect)  {
      // Get list of files from fileList, make list of files already on
upload list
      for (var i:Number = 0; i < _aUploadFiles.length; i++) {
        for (var j:Number = 0; j < _refAddFiles.fileList.length; j++) {
          if (_aUploadFiles[i].label == _refAddFiles.fileList[j].name) {
            arrFoundList.push(_refAddFiles.fileList[j].name);
            _refAddFiles.fileList.splice(j, 1);
            j--;
          }
        }
      }//for (var i:Number
      if (_refAddFiles.fileList.length >= 1) {
        for (var k:Number = 0; k < _refAddFiles.fileList.length; k++) {
          _aUploadFiles.push({label:_refAddFiles.fileList[k].name,
data:_refAddFiles.fileList[k]});
        }
        listFiles.dataProvider = _aUploadFiles;
        listFiles.selectedIndex = _aUploadFiles.length - 1;
      }//if (_refAddFiles.        
      if (arrFoundList.length >= 1) {
        Alert.show("The file(s): \n\n* " + arrFoundList.join("\n* ") +
"\n\n...are already on the upload list. Please change the filename(s) or
pick a different file.", "File(s) already on list");
      }
      if (_aUploadFiles.length == 0) {
        btnUploadMultiple.enabled = false;
      } else {
        btnUploadMultiple.enabled = true;
      }      
    }
    else  {
      _aUploadFiles.push({label:_refAddFiles.fileList[0].name,
data:_refAddFiles.fileList[0]});
      tiFileName.text = _aUploadFiles[0].label;
