TraceLog - Seeing the output window on-line

Trace Log

Trace Log is a free open source software that enables you to perform real-time monitoring on any server logs simultaneously. The main goal is to group all related log files into one tool so that you don't have search and dig for them. This tool enables you to attach any log files, such as Tomcat logs, WAS logs, IIS logs, etc.

If this is the first time you are use Trace Log, you need to configure and attach any necessary log files. Once attached, a configuration file will be stored locally in your user profile of that computer. The next time you use this software again, it will load the configuration automatically and you can begin monitoring the log contents immediately.

FileReference.download() don't save the file

Environment:
Flash, Action Script 3 




Scenario:
When creating a FileReference.download()  for downloading a file to user local hard drive the download dialog is open as it should but when I click the "Save" button I can't find the saved file.

Problem:
The FileReference variable is declared inside the download function and as a result of that he is a "local variable" (obviously :-) ).
When the download dialog is opened, the FileReference is unknown since he was declared inside the function. code sample 1

Solution:
Declare the FileReference variable outside the download function as a "Global variable". code sample 2


Code sample 1:

 
 private function startDownload(e:Event):void  
 { 
 var fileRefToDownload:fileRefToDownload = new FileReference(); 
 fileRefToDownload.addEventListener(Event.COMPLETE, downloadCompleted); 
 fileRefToDownload.download(new URLRequest(fileToDownloadURL), "this_is_my_file_name.jpg"); 
 } 


Code sample 2:


var fileRefToDownload:fileRefToDownload; 
  private function startDownload(e:Event):void  
  {  
  fileRefToDownload = new FileReference();  
  fileRefToDownload.addEventListener(Event.COMPLETE, downloadCompleted);  
  fileRefToDownload.download(new URLRequest(fileToDownloadURL), "this_is_my_file_name.jpg");  
  }
