View 6 RepliesI am writing a VB 2008 program to display and update records from a sql database. This particular form is used to display and modify retail store information records from the database.

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

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)

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

View 1 RepliesI need to setup an application to scan a barcode from a packing slip and the associated fulfillment items on a windows CE 5.0 device and update the inventory on the server. I'm using VB.NET. However, what is the best way to interact with the database? Integration Services, ADO.NET, RDA... etc... it's a bit overwhelming trying to figure out what I should use to interact with the database. It's currently an Access database, but I imagine I'm probably going to need to migrate it to SQL Server or SQL Server Express.
I'd also need to print the packing slip to a network printer from the device. Is there any way to do this?

View 10 RepliesBackground: I have a program that has implemented the two "classic" taxes for Ontario Canada: 5% GST and 8% PST. At the beginning of July (2010) the province switched to one combined HST tax of 13% for the most part. Effects and changes here but those aren't the main point of this question...
Question: What are best practices and good solutions to accommodate for future changes easily in retail taxes? Tax changes occur often enough. I'm sure there are a many SO users with good experience.
