The Reader objects all have an EOF marker, so you can change the code into

You can read alll the lines of a textfile into an array of strings, each string will represent one line:

Dim TextLines() as string
...

TextLines=objReader.ReadLines()
...
Maybe the text file is too big to hold in memory though.

As for favorite websites, the online help of VB.NET (I assume you're using the 2005 Express edition) usually gives a good start, for the rest there's www.gotdotnet.com 

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
