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]

View 1 RepliesThe idea is to scan a folder of images and then let the user navigate back and forth through the images using a couple of buttons.The problem is, I can only get it to return a single image, and not the whole lot.

View 3 RepliesThe app i am working on is for creating theme for the iPod touch... It has to deal with LOTS of images (100's potentially) There will be the set of default images, and then the user created replacement images. I started loading all the defaults into a resx file... thinking then I could just pull them out. now that I started setting the default, this sucks! lol the app will do this, on load it will set all the images (variables) to the resx images then when a theme is loaded, it will replace the default with the user image (if the user img exists) otherwise, the default stays. Then the "screen" is drawn to show the user. so, here is just the images to build the wallpaper, dock, and status bar...

I was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?

I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:

View 9 RepliesI am making an that uses an external dll which should hold all the images used by the app. I know how to do this i.e. add images to resources or imagelist, then return them using a function which is referenced to. But, I have no idea how to tag the images so that I can obtain an idea of the images belonging to that category.
E.g. My dll has 100 pictures of houses. When the person looks for "white" I should be able to look through my tags for white houses as soon as possible. And at any point, if I wanted to, refer to the images programatically (that part shouldn't be a problem). So the only problem is tagging, what is the easiest/requires least amount of code to be written for?
