Converting Javascript Bit Shift Code to VB.net

Question

I have some data that I am scraping from a local device on my LAN. It uses javascript to format the data, but I need to perform the same formatting in VB.net. Here is an abbreviated version of the javascript:

var n = 0x740900;

alert(((n >>> 8) & 0xFF) + 1);
//result is 10

n = 0x740a00;

alert(((n >>> 8) & 0xFF) + 1);
//result is 11

Essentially, I need to feed a variable (n in this case) into the calculation, and then I am returned a value.

From my research, the >>> is a zero-fill right shift operator. I've been trying to replicate it in VB.net, but the >>> operator isn't available.

Any ideas how I can replicate this in VB.net?

Is it just >> ? msdn.microsoft.com/en-us/library/dezyht83.aspx — SSS

It's a hex number that has the month and the year in it. The operation I am attempting extracts the month (10 is for October, 11 is for November, etc) — user1159415

Dim n As UInteger = &H740900
Console.WriteLine(((n >> 8) And &HFF) + 1)
'result is 10
n = &H740A00
Console.WriteLine(((n >> 8) And &HFF) + 1)
Console.ReadKey()
'result is 11

Awesome! That did the trick. The "And" was throwing me off as well. Thanks so much!
