As already suggested you need to use some third party component and you have to decide that by browsing through the list of available components in net. While deciding the component a lot will depend on how much you are willing to spend.
Download the barcode_label_activex.exe from the net. Install this application. Add BARCODE_ACTIVEX.ocx component to your VB Program. Go through the Code Given for this .exe file. And u will come to know th erest.

As already mentioned the barcode scanner works like a normal input device like a key board. so when you scan the bar code using the scanner any editable window having focus will be populated with the code. No need of any specific text box not even any application. Just ensure that the device is working properly and try that with a notepad.
There are bar code fonts you can download and install on your PC for the purpose. Just google "barcode font" and you will find plenty. Using this font you can print barcodes on your normal laser on A4 etc however if it is for a shop you may want to consider buying a barcode printer that prints on small sticky labels
I've worked with these before. And from looking at the specs of your scanner all you have to do is scan the barcode, the barcode scanner will decode the symbols and translate them into ASCII characters that can be read as text.
To make it easy on yourself. Drag a Text Box Control onto your form. Make sure the MultiLine property is set to True.
Start your program. Make sure the focus is on the Text Box by clicking your mouse on the text box.
Scan a bar code. Press the button and then you should see the text appear in the text box.
You shouldn't have to worry about special drivers. Your scanner acts like a USB keyboard input and should be detected as such. And since it acts like a keyboard, you should receive input similar to that you would receive from typing on your keyboard.
For coding purposes. You should have a careful look at your documentation. Oftentimes a scanner will send a special character that you can check and look for in your program to verify that you are receiving a bar code scan and not just regular input from the keyboard. You can then write code to set the focus to a text box or read the input into a string variable which you can process later.
And just as there are special characters at the start of a bar code, there should be special characters at the end of a bar code scan. You need to write code to respond to these special characters to process the bar code information at that time: whether that be to enter a sale, update your inventory, etc.
