I have a PDF file with n pages, I need to split it to n files. On each page I have barcode, I need to recognize/read barcode. If I have two files with the same barcode I need to merge them.Can anyone recommend an .net component or exe or something else that will help me? It can be commercial.I have tried:itextsharp - only split and merge files dotimage/aspose/idautomation - only recognize barcodes and it very expensive a-pdf - not always recognize the barcode and not merge/split two files.
I have written an vb.net application, named vbapp.exe. And I would like to use vbapp.exe to shell an external .exe file and this external .exe will create a file in the folder in which the external .exe file is located.However, the external .exe file will not recognize its own folder, on the contrary, it will think that its own folder is where the vb application, vbapp.exe, is located.
I'm building an application in which a certain CSV schedule is read and searched for time and date values.
I want to read each cell in the CSV file with a streamreader and have VB determine if the contents of the cell represent a date (like 31-10-2011), a time (like 22:30) or random text data which is not formatted like a date or time.
How can I make VB recognize a string as either a date, a time or neither one, so I can use this string formatted as Date, Time or discard of it?
The contents of the CSV file will look something like this:
Although the CSV file will never contain much data, the position of the date and time fields in a row may vary, so I cannot tell VB which cell to read as date/time. It has to recognize the value as date, time, or unusable text.
Dim CSVReadline As New System.IO.StreamReader(schedule.csv") Cellcheck = CSVReadline.ReadLine() String = Cellcheck.Split(";") For i = 0 to 10 Scheduledate = String(i) ............ etc.
I've made an interface called ApprovalEvent in a separate file with the namespace myproject... I've also made a class called PurchaseOrder... it's also in the same namespace, just in a separate file. Whenever I try to make PurchaseOrder implement ApprovalEvent it always says that ApprovalEvent is undefined...
How can I make the class recognize that the interface exists but is in a different file?[code]...
I am creating a new program whch is Document Tracking System Integrated with Barcode which one of my project..my problem is I am new in vb 2008. I create a random numbers and I want it to be converted and into barcode lines with its corresponding random numbers.and be printed.. example 64254168 convert it into barcode.
I need to add barcode reading feature to my application. I donot know how to enable my application to read barcodes. I mean a scanner should read the barcode and having matched the article no. in database, info should be displayed on the screen.
I am about to develop a software (VB .Net) that generates and reads barcodes. The backend db is sql server.
1. I have a major id and sub ids. For example I have major ID A, and subgroups A0, A1, An. Also I could have more detailed subgroups like A01, A02 and so on.
I need to generate and print these barcodes from my VB application.
2. The handheld scanner is used to read the generated barcodes and pull their data and show them on the screen.
I have EAN-8 standard barcode information stored in the DB. I am trying to generate a report in MS Word Document format. The requirement is that I create barcode in the document using the stored info from DB. I am using VB.net (.NET Framework 2.0).
I am about to develop a software (VB .Net) that generates and reads barcodes. The backend db is sql server. 1. I have a major id and sub ids. For example I have major ID A, and subgroups A0, A1, An. Also I could have more detailed subgroups like A01, A02 and so on. I need to generate and print these barcodes from my VB application. 2. The handheld scanner is used to read the generated barcodes and pull their data and show them on the screen.
I made a small application in VB.NET that allows user to scan a bunch of barcodes and save them in the database.Application works both for the regular computer browser and handheld pocket PC.Barcode can be either scanned into upc text field and automatically submitted to db or numbers can be manually added into upc text field and pressing Enter will add it to db.There are also two buttons on the page. One button "Clear" is to clear upc field in case user started a manual input and didn't like it. Second button "Exit" logs out a user.
User should just scan a barcode and it will be automatically added to db without pressing any Submit button so user can go through a lot of barcodes fast. In order to achieve this, upc text field has AutoPostBack property set to True.Then in the Page_Load event if len(upc.text)>0, then data from upc.text gets submitted to db and upc.text gets empty again.If len(upc.text) =0, nothing happens.So it works fine in case of a handheld. It scans and sets upc.text to empty string. So if I scan and press Exit button after that, I just exit without a problem.
But there is a bug if I input a upc number manually and then press an Exit button for some reason. Pressing a button causes the page to reload and number gets submitted to the database anyway though I just wanted to exit. In fact, if there is any data in the upc field, any action, pressing Enter, pressing the button, clicking with mouse on the screen, causes that data to be submitted to db in the page_load event.How can I avoid this situation if I still want items to be submitted automatically without pressing any button while scanning?
I want to develop a small application that reads in scanned barcodes into a database table - Would a vb.net form based application that connects to the database be best approach? What I'm think is each time the user scans in the barcode - a message appears on the form saying the barcode that has been scanned.
1.Would I need to program anything within the program to check whether the barcode scanner is connected (or is this not necessary since it works like a keyboard device?)
2. How could I automate the scanning in without requiring any user intervention like a button which saves it to the database - so basically as soon as a barcode is scanned in - it is saved to the database and the next barcode can be scanned in etc.
i am using this code below to compare two strings then count the no. of mistakes when text is added into textbox2[code]but when enter key is pressed the code doesn't recognize the enter even thought it is correct and counts it as a mistake.
I have an data application I made for a company. I want them to be able to hit both the Tab and the Enter key to select the next control in the tab order. I would also like to turn the background of the currently selected control a color other then white. I have been trying for days to find a solution but trying to interpret the msdn library is making my head spin..For some reason, the below code only recognized the enter keyup and not the TAB key.My Code here:
Imports System.Windows.Forms Public Class Form1 Private Sub TextBox1_KeyUp(ByVal sender As Object, ByVal e As
I am trying to teach myself visual studio 2010 using VB. However, I am having trouble with functions. I have created one that looks as the example code given in the text but I keep getting an error message.I include my code but whatever I have tried, like declaring Dims all over I can't get it to recognize that GCD is a function rather than a variable.
Partial Class Intergers2 Inherits System.Web.UI.Page Protected Sub SubmitButton_Click(sender As Object, e As System.EventArgs) Handles SubmitButton.Click[code]......
i would like to be able to type a complete word, and if that word is in my list of sound wav's, then to play that wav.. basically, i need it to find the space before the word and the space after, so when i press the spacebar, it will only try to locate the last word in between those spaces, and if the word is tru , then it would say tru , if i type in tru jade, it would say tru . . then say jade .also, if possible, to pick up the first typed word also, which would not contain the space before it.. how to get my app to recognize my voice after i name it pookie ,so when i say " pookie, load vb ", it would say, " sure tru jade, you are the best, of course i wil l " and shut down my p.c.
the loading of the app should not be a problem for me.just getting my app to listen for pookie, and a command..links are also welcomed to other good pookie sites..
How do I make my program know that time is passing and interact with it? Currently I'm trying to use a method like this: Imports System.Globalization Private Sub CurrentTime_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CurrentTime.Tick Dim date_info As DateTimeFormatInfo = _ CultureInfo.CurrentCulture.DateTimeFormat() ToolStripLabel1.Text = Now.ToString(date_info.ShortTimePattern) End Sub
That sets the current time to ToolStripLabel1.Text it looks like: 10:25 PM. Then I made another timer, realizing I couldn't interact with Toolstriplabel1.text because the time contains " : and PM", and this timer does this: Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick TextBox48.Text = Val(ToolStripLabel1.Text) End Sub
Basically it takes the value of toolstriplabel1 which would be "10" it gives a variable 1-12 in accordance with the current time. Then I have another timer that handles the main process, and in My.settings I have a variable: My.settings.12hourspassed
So I was going to use My.settings.12hourspassed as a variable such as My.settings.12hourspassed = My.settings.12hourspassed + 1 - whenever the time (textbox48.text) goes to 12. Private Sub Timer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer.Tick If Val(TextBox48.Text) = 12 Then My.settings.12hourspassed = My.settings.12hourspassed + 1 If Val(TextBox48.Text) = 12 Then TextBox48.Text = "1" End Sub
The problem is that I cant do textbox48.text = "1" because another timer is making it the value of the current time.. So whenever textbox48.text = 12 it constantly does: My.settings.12hourspassed = My.settings.12hourspassed + 1...
I know that this method completely skips an hour and such.. accuracy isnt all that huge. Any way to tick off whenever 12 hours have passed? and if the program is turned off a way to compare the current date with the date the program turned off at to see how much time has passed while the program is off?
I am stuck on what 'should' be a fairly simple thing to solve, however after a good search i haven't got very far.
Basically i am pulling data from a database which might have multiple lines of data, however for one particular task i only want to grab the first line of text (as a sort of preview).[code]...
i want to recognize the gps port and use in my program to send a command, i have the script to send the command through the serial port but now i net to put the com port manually and i want this automatic.

But then I want to bink key K to be recognize as Numpad 7 I have followed all the suggestions given in the said thread and found no luck. I'm just a newbie when it comes to things like this.
I need to create a program, and now I want some advice from you, as I simply don't have so much experience to get round it.Firstly, I have issue with a checked list box. For example, there will be 5 items.I want each item to have a different value, because it will be a things people will be buying, and so when someone clicks on item1, the value I assigned to it will be output into a label, so user will know how much that item costs. I know how to output it, label1.text = CheckedList Box1.SelectedIndex but how do I set for example for item1 value of 5000, for item2 3500 and etc? Secondly, I will have a page for users, where they will see history of their bought items. But what's the best way to store the price they paid, item they bought and date? It should be able display for each user their own bought item history.I hope you understand what I meant, as I'm quite new in programming so It was a bit hard for me to express what exactly I want. If you didn't understand something, or need more information please ask me. I hope someone will be able to help me, as I really have a bit of a struggle with it. At first I wanted to use plain .txt file to store and output into textboxes, but it wouldn't be aligned, look nice and etc. Then I thought about database, but how to recognize which item to display for each user and etc.
For some reason , that I can not catch yet , when I installed the office 2007 this module can not be downloaded running from 2003 to 2007 version.

So I wrote a program, which goes thru the authentication of a website, using a 'webbrowser' element within the program, however, when I want to open a page in an other browser e.g.: Firefox after I went thru with the Auth. in the application , it seems as there have been no authentication at all.
Do I need to set something with the cookies? Or how would firefox know that I am already logged on on another browser? all is in Visual Basic 2008.
I've a php script that if the user ahs the privilege to download and image the image is sent to webbrowser but if the user has not the privileges and xml with the info is displayed.[code]
I am trying to create a program that will be able to recognize handwritten numbers in a picture. Right now, the program locates a rectangle that the numbers are in. The numbers will generally be in the range between 0 and 9000. I have found some stuff about ink recognition, but I dont think that is the same. Also, is there anyway to be able to make the program 'learn' from the style of the handwriting? I'm using VB.net 2008
