Integrating A Barcode Reader In Vb 2005?
Nov 27, 2009
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.

I 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?

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?

I 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.

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 have two buttons: show button and next button. I want the show button to show the first result and then for every click of the next button, I want to go the the next result. I did this code for the show button:
cmd.Parameters.AddWithValue("@sex", TextBox4.Text)
dr = cmd.ExecuteScalar
If dr.HasRows Then
While (dr.Read)
TextBox1.Text = dr(0)
[Code] .....
Now the number of rows returned is 5. But on clicking the show button I can see only the last row in the textbox's. Then how to see the first row by clicking the show button? And how to see all rows one after another by clicking the next button? I need to use:
dr.NextResult()
to loop through the fetched data. But I cant place it properly in the next button code. How to do the code for show and next button to get the desired result?

From few days I am doing efforts to read web pages using webbrowser control in my desktop application. But it is very slower than my expectations(because I want to read lots of pages in minutes and browser control reads almost one page in 5 to 10 seconds), what I need is to read two or three tags written in web page.
So finally I decided to use something, which can give me only source code of page. I think StreamReader will help me to read it. I am not sure if it is flaxible with my purpose, or something else is there which can give me only html source code of web page.
I have written this code to read html code, but it gives error.

I'm making a browser and for the favorites I'm using a reader and writer to read and write new favorite to a .txt file. Now if I edit the text file manually and load up the browser, the favorites show up as they should but the problem comes in when I add the a new favourite and then reload the application. Once reloaded the favorites seem to copy what was originally in the file and then whatever I added last at the bottom.
Here is the
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
WebBrowser1.Navigate(TextBox1.Text)
ListBox1.Items.Add(TextBox1.Text)

I have a program that reads a text file tab delimted using OLEDb .I need to be able to allow the user to insert a user created record into the file which I can do.
The problem is I need to be able to let the user edit that record. From my understanding you can not edit or delete with OLEDB only insert So I thought I would read the file using stream reader, find the line I want to edit and just delete it, rewrite the file, then let the user insert a new record
If someone has a better way to perform this operation I am open its just the best way I could find with my limited knowledge and the reading and researching I have been doing thus far.
So I am trying to step-by step and first read the file which seems to work then find the line that would need to be deleted. So I was trying to use the
line.startswith method. I am using msgbox to see if that works before I continue but it doesnt seem to work I know my file has several lines starting with "Active" but my msgbox returns "False"
Here is the code I have so far

I have a SQL query that I want to integrate into a VBA subroutine in Excel. I have had some success using the Macro Recorder to call up the SQL query (throuh Microsoft Query) in the past. However, the SQL code that I have for this query is significantly larger than previous attempts.When I record this one through the Macro Recorder is trips up because there are too many line breaks integrated into the recorded code. To get around this I have tried to manually update previous (successful) queries with the larger SQL code that I want to use, but without success.I was hoping that someone out there has some experience in integrating the standard SQL query code (SELECT xxxx, yyyy, zzzz, *nnnn FROM aaaa, bbbb, cccc, *nnnn WHERE 1111, 2222, 3333, *nnnn) into VBA.

I am having an issue with both Adobe Reader and FoxIt Reader when trying to print a PDF document. Both issues are different but a solution to either one will allow me to fix my issue.The issue I am having with Adobe Reader when trying to print using the following code is that it will not print it to the network printer I specify but just the default printer.
Dim AdobeReader As New Process
AdobeReader.StartInfo.CreateNoWindow = False

I have been asked to create a project in vb.net which needs to integrate a java class created by Apple (Autoingestion.class) to pull sales records and so on.I found out a couple of questions here on stackoverflow but none of the answers given worked for me when trying to integrate this java class in my .net application.For example this question seemed to be what I really needed but when trying to compile this java class (I decompiled it first using Java Decompiler), it generally throws some errors.All I need is to use this class in my application to invoke a method.Does anyone know how to pull this out without much ninja-ing?
