Forms - Generate Barcodes - Reading And Printing
Jul 17, 2009
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 want to be able to code a small system that reads a set directory, for new PDF or Word DOC file types.
Then i want to print them.
I understand, with reference to this thread, - [URL]
and this one - [URL]
that i can use MS Word automation to print the document, but i would like the application to read the folder constantly in real time and then print what ever is 'new' in the folder.
Would there be any advantage to code my own print driver?

I have a problem with a loop that I'm writing where it is just reading and printing the first line of a text file.
ofdFile.Title = "Choose file to read"
If ofdFile.ShowDialog() <> Windows.Forms.DialogResult.Cancel Then
sr = New StreamReader(ofdFile.FileName)
End If
[code]....
Do i have the .peek set up wrong where its only doing the first line?

I am reading a txt file and displaying the contents into a listbox but it generates an empty listbox item at the bottom of the listbox. I am splitting the textfile each time it finds a new line in the txt file;
.Split(vbNewLine)
The problem there is always a blank line in the txt file at the end and so generates a blank list item. How can I remove this blank list item from the listbox? Is it best to try to remove the blank line from the txt file first or the empty list item from the listbox after the file has been read?

I wrote a program to print deposit tickets using pre-printed deposit forms.The forms are the ones used by Peachtree Accounting.I have used this program with three different printers.All three printers are HP.Now I am using the program but the printer is a Lexmark and the print no longer lines up with the form.The print is now about 3/16" below the place where it was printing.I can change the program to reduce the starting place of the print but if another printer is used the print will be off again.If the HP printer is used then the print will be too high.How can I take this in account for each printer that may be used?

I have set of WCF web services that I need to generate a Windows based test client. Does anyone know of a tool that will take as WSDL and auto generate some basic forms based on what is in the WSDL. Any thoughts as to how I can get a basic form with fields/labels without having to explicitly make a form.

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 want to automatically generate VB.NET forms using tables from a SQL Server database (one form / database table). It is perhaps possible with writing custom custom code for it, but if there is already some feature that does the job that would be great (database has 40+ tables, manually doing this is a tedious task).

This is my first post here so forgive me if I am not following any correct protocols. I am attempting to generate a DataSet and bind it to a datarepeater object. I had been doing this at Design Time and was getting an error message when filling the dataset when the form loaded. So I am basically createing the dataset in my code now when the form loads and binding it to the datarepeater. However, when I attempt to bind the dataset I get a NullReferenceException - even through I know that there are 60 rows of data in the dataset table.
[Code]...
As you can see i have several debug messages in there. I get the error on the last line when setting the datarepeater data source. I try and get data for a specified lot - if it doesn't return any values I create some values in the datatable and add them to the DB. On first load when there is no data this works perfectly. If I then close the form and reload it, it will display fine. However, if I change any of the data (database is updated) and then go back in again, I get the error above.

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'm making a personal program (So it doesn't have to look nice or be super sleek) that is basically an alarm clock. I set the time and date, it writes it to a text document then it reads it from the text document back into another textbox that is hidden and compares it to label1.text which is my system time and date.the problem is, I have it so that I can add multiple dates in one document so when I enter one it'll do as so [code]how can I make the program read 1 line, wait for it to match the label, (I already make it display a message box) and then after that is all done, go to the next line and wait for it to match. etc etc.
