I am using Richard L. Grier's Enhanced Serial Port dll to read input from a serial port barcode scanner I notice that the datareceived event fires only once per barcode scan, but the delegate sub fires twice per barcode scan. Once for 1st half of Barcode , 2nd for 2nd part of barcode This makes it hard to capture the full barcode so it can be passed to routines in my vb.net 2008 windows application In Richard's example 'Test Enhanced Port' program he sends it to a textbox using .selectedtext and it works fine Richards Delegate code ......................
Public Delegate Sub DisplayData(ByVal Buffer As String)
'This delegate routine marshals receive data from the receive thread context DataReceived to the Windows Form STAThread context
Private Shared Sub Display(ByVal Buffer As String)
[code]....
I am trying to set a variable to the full barcode to pass to routines, instead of writing to a textbox but am not having any success

I am a student and I am about to make a program that will use a barcode scanner well ofcourse to scan a barcode. My problem is i don't know what library to use and what certain things i need to do so that when i am going to scan a barcode it'll be something like show it on a textbox and pull something from the database. i've actually research some. i've seen mscomm1 (not so sure about that) and POS for .net (haven't fully understood its use) were those will help me develop my program?i have a metrologic ms9520 Voyager barcode scanner. and i am going to create a program for it in vb2005.

A friend of mine called me to that we need a program for our club that when a member will enter in club gate so first of he will have a card upon which a barcode will be printed and through barcode reader his code will be scanned and will be find out that whether he is a temporary member or regular member or absent member or other. Only regular members are allowed to enter into club and allowed to avail all services of club. Now the question is that i dont know that how the custom barcode will be created and how the scanner will be controlled with vb.net?

I just realized the OLD tutorial here is still works. Here is the webpage link But that one is iText 2005. And now is 2011, I wonder if there's any nearest version of iText for vb.net ? didn't found the iText for vb.net in 2008 version.... is there anyone could clarify this?
Because that 2005 version is using .Net framework 1 or 2. Very old... now I'm using version 3 & 4.

I am writing an inventory control application in which a barcode scanner will be hooked up to a laptop computer in our shipping/receiving department. What I'm wondering is, whenever a shipment comes in and the receiving clerk starts scanning the products, what exactly do I need to do in order to setup our database so that the scanner recognizes which vendor/product etc. and puts the data in the correct tables. I've written inventory control apps before but never one that incorporated the use of a barcode scanner.

So i bought a cheap USB barcode scanner to play around with. So far pretty simple to use, on theing thats baffling me though is after the keyUp event and the string parsing, how do i reset the value of the textbox that reads the string to make it wait for a new keyup event. Eventually i'm going to try adding rows to tables and autocompleting cell values based on the parsed string. So what would be the best way to start looking at this?

Is there any Visual Basic SDK that will let me scan a barcode from a webcam, not an image? I have seen some that read from files, but this is not what I am looking for. If possible, I would love it if this is free!

I have downloaded the BarcodeLib.dll from[url]...
And however, my barcode scanner cannot read the hard copy barcode images that i have printed out as the following.[url]...
I have done research and some articles mention that dimension of the images will effect the readability of the barcode.
May i know what is the correct dimension to make my barcode images to be readable?

We are using USB barcode scanner to scan material barcode labels. These labels are from our vendors. We does not have control over the label generation. We are using USB barcode scanner for scanning purpose. We want to capture USB barcode scanner output. Normally the scanner returns output in the place holder in which the cursor present.But we do not put writable text box for the cursor. Instead of write allowable text box we want to put locked or readonly text box in the screen and want to capture scanner value.How can we do?Assume that our barcode scanner does not support serial ports.

I've recently been asked to develop an application for the Motorola MK4000, an all-in-one device with a built-in barcode scanner. It runs Windows CE and supports VB.Net.
I've never written an application for Windows CE, nor using a barcode scanner.
I'm familiar with VB.NET so I'm confident I can figure this out, how to use the barcode scanner with possibly some example code of how to detect it and read data from it.

I have to read a 2D barcode that's encoded with base256. When I scan the barcode, it sends different characters as it comes from the keyboard and it changes the focus, turns visual studio in full screen, give the command to send to printer from notepad++.
I guess it reads ALT + TAB, CTRL + P, ALT + SHIFT, etc. and i can't capture all the bytes from the barcode.
I tried to capture the event on textbox KeyPress method with e.handled = True and e.keyChar added to the bytes()
On form.load I set:
Me.KeyPreview = True
And tried also on form.KeyDown with no luck.

I bought acheap USB barcode reader so i could play around with some hypothetical situations. I've managed to get a good chunk of stuff worked out, and had alot of fun along the way. But i thought to myself what if the same tag is passed back along the chain due to production defects and requires remaking.
When it returns to the station to be retagged complete, how do i set the condition for it to search to see if the bar code string already exists in the database prior to either adding a new row (if if returns negative) or to append a cell in the table if the search retuens a positive result.
