Initializing a Variable The Right Way

Simple and short, this is how you can initialize a variable in VB.NET.

Take the following for example:
Dim dirInfo As System.IO.DirectoryInfo = New System.IO.DirectoryInfo("C:\")

The first part:
Dim dirInfo As System.IO.DirectoryInfo as I would like to call it, “dreams” about a variable dirInfo which belong to a type of System.IO.DirectoryInfo.

The second part:
New System.IO.DirectoryInfo("C:\") actually realizes your dream, it “creates” that variable. It’s only now that your variable dirInfo trully exist.

You can also initialize a variable like so:
Dim dirInfo As System.IO.DirectoryInfo
dirInfo = New System.IO.DirectoryInfo("C:\")

One of the error message that you may get if you haven’t been initializing a variable correctly is “Object reference not set to an instance of an object”. The following code can cause an error, since the variable dirInfo is still a “dream”.

Dim dirInfo As System.IO.DirectoryInfo
dirInfo.GetDirectory("C:\")

As in life, good things starts with a dream, and you have to do something to it, before it can be realized.

It’s definately a win-win situation here.

1. A bit of history about trackback and pingback

2. WordPress Trackback Tutorial

3. Youtube video explaining Trackback

Installing Microsot Loopback Adapter Before Installing Oracle or SQL Server

If you’re going to use Oracle Database or SQL Server in a local environment or in virtual machines, make sure you install Microsfot Loopback Adapter first before you even try to install Oracle and SQL Server. Typically, the computer on which you want to install Oracle Database is connected to the network. While doing an installation, both Oracle and SQL Server will check what the current IP of the current computer is, and use this IP in several places in its installation. While this itself isn’t a problem, it might still cause *some* trouble after installation if:

1. You had DHCP dynamically assign new IP for your computer
2. You want to run database server locally in a non-networked computer but was connected to the network while you were installing Oracle or SQL Server.

What you need is the Microsoft Loopback adapter. The Microsoft Loopback adapter is a tool that can be used for:

1. Virtual network environment where network access is not available
2. Assigning a fake constant IP to be used by Oracle or SQL Server installation

Site Indexed in Google Within 5 days

seo sem website trafficFinally got my site/blog indexed with Google search engine within 5 days. That was considered quite fast judging that there wasn’t any link building activity done yet and there wasn’t any backlinks coming from high traffic sites or anything of that kind. No softwares tools was used whatever. Simply submitting url and registering my sitemaps in yahoo and google manually did the trick for me. I’m sure writing at least a post a day in WordPress and using a plugin to create and submit the sitemaps for yahoo and google helps a lot as well. I know that there are people who can get there site indexed within 24 hours though. Oh well, I’m not that lucky but yet I’ve done it anyhow.

So, how long did it took you to get your site indexed in Google?

I personally prefer megaupload compared to rapidshare. IMHO, it’s easier to search for files in megaupload using only google itself, while rapidshare doesn’t allow those pages to be indexed by Google.
