View 12 RepliesI am planning to buy a USB barcode reader. I don't want to use it as a keyboard wedge scanner.But before I do I wonder if it's possible to see whether the input comes from a barcode reader.I need a Windows Service that detects whether a barcode is scanned and depending on the text on the barcode starts another program.Is this possible and has anyone experience with this?
View 4 RepliesI 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.
I'm looking at creating an asset management system for all our electrical equipment, the equipment already have security labels with barcodes on them. What I am wanting is to be able to do is create a form where i can state some general information about the piece of equipment and then scan a barcode to register the equipments security number. so that if an employee needs to use that piece of equipment off site then I can just scan the barcode and register that the employee has taken the equipment.
My understanding is that the barcode reader is generally plug and play and acts as an input device? So what I would need to do is find a way to identify which input device is used, and if it is the reader find a way to assign a labels text to the value that has been read, rather that insert it into a textbox? I also want to display the actual barcode itself above the label, so I assume I would need to re-generate the barcode as an image and then display the image?
Im creating an EPOS system and nearing the end of the application.I need to connect my newly acquired barcode reader to the form in vb.net so that whenever I scan an item in the items ID number appears in the necessary textbox.After some research I have bought the relevant barcode reader making sure it supports the relevant barcodes including retail.I have plugged it into the computer through the usb port, it has installed automatically all of the relevant drivers, and below is the code Im using in vb.The below code is include for where the form loads up:Me.KeyPreview = True
View 4 RepliesI tried to configure my barcode reader to act as a keyboard wedge but it didn't work. (I'm using Metrologic Voyager MS9520) I figured out that the scanner still uses the serial port RS232. So i tried to use the MS Communication Control in VB 2005.

View 2 RepliesIm using VB2008... Net framework 3.0. Basically I have a barcode scanner that is sending the software data...Everything is working fine if I interface the scanner as a keyboard wedge and set the scanner suffix as 'Enter'...In the software I have an event handler on keypress.down...
If keycode.Enter then
.....
.....
....
etc.
However as a RS232 interface I cant get the same result? Hyper terminal reads it perfectly. I've tried all the keypress options but it doesnt work (I assume because it's not actually a key press). when the textbox recieves the CR/LF from RS232? The scanner that does keyboard wedge interfacing is not an option as it is far too expensive for my project.
I need to implement a USB barcode scanner into a VB project. With no code directed at the scanner, it works when a textbox is selected. I need it to put the numbers in the textbox whether the textbox is selected or not (as long as the form is open). I would also like it to save the numbers to a variable.

As a declariton at the beggining of a form? or as as VB resource?and then how those it bind a to a dataGridView? How can I loop through each rows once is bind to use the contents of the column/row?I can perform the above function easly inside of MS Access using VBA. I have gone through various books from WROX but none of them show a clear example or the code is obsolete.

View 1 RepliesI 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 ......................
