View 3 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 5 RepliesI am trying to make a program that would allow me to track all my customers and flights. My idea is to have a label for every seat of the plane.

View 18 RepliesI 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.
how would you identify the shape of text like inside a scanned document containing text and graphics?In a perfect world,users would never enter data in the wrong form,files they choose to open would always exist and code would never have bugs.[URL]

I am attempting to write a playlist for my media player which is already built. I have found a way to build a playlist for it but it would be helpful if I could save the contents of TextBox1 to a text file without using the save as. I am trying to get over a user inputting a file name for the finished text file so is it possible to write the file c: est.txt without using the save as dialog? I have found that I can use a vbs program file which creates a playlist in a folder. I save the vbs file text to the textbox then save it as a vbs file in the playlist directory, then execute the finished file to make the playlist.
View 5 RepliesI have researched the net, youtube, and the msdn DB, and still can not find the working answer I am looking for. I would like someone to show me how you would save the contents of "Listbox1" to a .txt file using the "Save As" Option. I know how to hardcode a savepoint in, but since there will be multiple users I would like the option to be up to the end-user.

View 5 RepliesMy question is simple (the answer may not be...), What I am looking for is a way to save a file as an encrypted file (so know one can open it except in visual basic or a way to save it with a unique ending that only visual basic will recognize. I will also need to know of a way to open or load the file to.
This is going to be used in a game I am working on (and yes...I know visual basic isn't really meant for games, but it is coming together pretty well). I was originally going to have it save as a text file, but then everyone could open, read it and even change there stats. That is what this file will contain, the stats for their character, and when they load it, it will place the values into the correct spot.
I am a partial beginner or intermediate coder, I can understand code, I just don't know all there is, like saving and loading, and this is probably a little harder.
I have a website written in .net 4. I'd like to include a save button on one the pages that will save the webpage as a mht file. This way the user can save the page as a mht file type on his/her desktop without have to use the browser toolbar.
I'm currently working with the following code but I need to modify it so it to capture the url of the current page the user is viewing verses hard coding the url into the button click event.
