I'm sorry if the title is misleading but I have to develop the format for a barcode (either 1D or 2D, doesn't matter). The barcode needs to include a Purchase Order #, Bill of lading #, as well as the Line #, product ID # and quantity of each item that appears on the purchase order. Here is what I've come up with so far:

View 2 Repliesi am developing a system will be able to detect motion. up to now i am able to stream the video that is connected to my PC to VB.NET. Now i want to switch between the webcam if there is more than one webcam connected to the system. For example, the user of the system will be able to chose any webcam that is connected to the system. I am able to detect all the webcam and display those devices into a ListView. But i don't know how to change the steaming video when the user select the device. Now the video screen show the image form the default webcam.

View 12 RepliesI'm looking for some advice for an application I currently developing. I'll try to keep this as brief as possible so if additional info is need just let me know.I'm developing an Winforms based event tracking system using VB.Net (VS 2008 Pro). The application collects data via serial bar code scanners and stores this data within a MS SQL Express db located on the same Windows XP Pro workstation that the application is installed on. When the application receives the formatted string of data it checks the db table and sends a reply back to the device indicating whether the data is a duplicate. I have written a PortManager class to handle the serial based devices and this functionality is working well.
I have now been asked to incorporate a new type of collection device into the system. The new device is running embedded Linux and uses TCPIP (POE) rather than serial communication. The device manufacture has assured me he can provide a string from the devices integrated scanner in the same format as my serial based devices.
If possible, I would like to utilize the current application and just add the ability to use the TCPIP devices to it. I was thinking it might be possible to just add a new class (similar to my Port Manager class) to handle the TCPIP based devices.I'm really at a loss as to the best way to approach this. I'm just not that familiar with collecting data from a Winforms application using a TCPIP based device.
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?
am developing an inventory management system. have two listview controls. one for ITEM and another for details pertaining date, quantity, cost, issued to and so on. i want a vb.net code that if a given item in listview A is clicked, listview B details are cleared and then the details of that item are loaded and displayed on listview B.there is no criteria of loading like between a range of dates; just all records in the database.

View 3 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 ......................
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

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.
View 1 RepliesI have a USB bar code scanner that is acting as an HID keyboard emulation device. I want a web page that, for testing purposes, pops up a JavaScript alert when a scan is done. I don't want to tie the event to any visible control such as a textbox so thus, I won't have focus on any control to capture the scan input. Can this be done? I'm using VS 2010 with .NET 4.0 and VB.NET with a Symbol USB bar code scanner.

View 3 RepliesI need to create a number of barcodes as images on a page from a set of UPCs from a database.Additionally, I also want to be able to produce barcodes which can print as labels to a Dymo LabelMaker.Googling turned up several options, but it seems that for the LabelMaker it'd be wise to produce the barcodes as PDF? So, I started looking into iTextSharp which seems good (and free!)Looking fora simple way to render a Barcode Image to a page, I found this, which looks to do exactly what I want, but I can only get it to work locally. When uploaded to the server it just shows an empty image.I have checked and double checked the web.config file contains everything required and am pretty sure that Adobe Reader is installed on the server (as was suggested by another post in the link). There's a post in the link which says
I just wanted to put a small update for those running IIS7, if everything works fine when running locally in VS debug mode, but you get a red x when accessing it remotly, you may need to add the handler in the section as well as/or the i.e.Which sounds like it's answering the problem but doesn't..url...Part 2 of my question is, am I heading down the right line to print the individual bar codes to a LabelMaker by using iTextSharp?

View 2 RepliesI am quite green to VB .NET and it start occuring to me that I am doing things probably in a very ineffective way.Anyway here is the problem I have datasets, consisting of integers there is set 1 which is of format ID, ID2 - ID here is unique but different ID can refer to same ID2. Before I start reading in the data I have unknown number of these entries (ID and ID2 can be at least as high as 99999999)
Then I have a second data set of format ID2 here is the same as in the set 1 and it can contain several PID entries (all integers). In this set the ID2 is unique and again for one ID2 there can be unknown amount of these PIDs, same PID can occur more than once.

I am a self taught "developer".I use the term loosely because I only know enough to make myself dangerous. I have no theory background, and I only pick up things to get this little tool to work or make that control do what I want.
That said, I am looking for some reading material that explains some of the theory behind application development especially from a business standpoint. Really I need to understand what all of these terms that float around really talk about. Business Logic Layer, UI abstraction level and all that. Anyone got a reading list that they feel helped them understand this stuff? I know how to code stuff up so that it works. It is not pretty mostly because I don't know the elegant way of doing it, and it is not planned out very well (I also don't know how to plan an application).
