How to Flush DNS Cache in Windows XP

If you have a domain and set a new nameserver for your domain, your computer will not access the server behind your new nameserver. It’s happened because your computer cached the DNS so when you trying to access your server using the domain, it will always redirected to previous server. The DNS cache  will be updated automatically after period of time, max time for this update is 2 x 24 hours.

To manually flush your DNS cache on Windows XP, you can use this command in command prompt. Open your command prompt by pressing Windows Button + R, then type cmd.

Use this command.

ipconfig /flushdns

Access CPanel behind company proxy firewall

I was having problem accessing my web server from my company, my company network only open port 80 for internet access. So it would be impossible if someone trying to do to access CPanel behind this firewall.

But there’s a way for us to access CPanel via port 80 on our server, there’s no change at all both side our network or server. To access CPanel behind company firewall we can go to, replace the with your own domain. For example

By using this technique we are bypassing the port on our server, and accessing the port 80 over CPanel. So we gain access.

The System Cannot Execute The Specified Program C++

Today I made a simple console application using Visual C++ 2008 and it was runs well on my development machine. But the problem occurred when I run the application on another machine, the error says “The system cannot execute the specified program“. I was guessing the problem occurred because of missing library or something, after short analysis both machine have the correct and the same library. So what’s going on??

I googled for this error and found this article, it explains how this problem occurred on compiled C++ application. There’s two type of build on VC++ ( Debug and Release), my application was built in debug mode and we can’t re-distribute the application on debug mode. The built program in debug mode only runs on development machine, so in order to distribute my app I should build my application in ‘Release’ mode. Time to switch from ‘Debug’ to ‘Release’ mode,

Open your Visual Studio->(Open Project)->Project->(project name) properties

select the Build Tab, in configuration option choose “Release”.

Rebuild your project, you will find “Release” folder, your released application is in there.

Simple Powershell FTP

With Powershell we can do FTP transaction really easy. The best feature from Powershell is we can use any dll library in our script, we can import .Net libraries and etc into our script. The script below is simple FTP to upload file to FTP server. In this script I’m using System.Net.WebClient to handle the file transfer.

$ftpuser = "user"
$ftppass = "12345"
$ftpserver = "localhost"
$file = "C:\test.txt"
$filenewname = "test.txt"

$webclient = New-Object System.Net.WebClient
$ftp = "ftp://"+$ftpuser+":"+$ftppass+"@"+$ftpserver+"/"+$filenewname

Python for Windows Mobile

Hello, right now I’m doing development some project using Python for my new company I’m working on. I thought Python will be boring, but Python changes my mind!
