I've easily found various QR-Code generators, but I need to use the data stored in the barcode on a regular desktop app using VB.Net and a WebCam or eventually an flash, javascript webpage to do the job.
Is that possible? Any products or tutorials avaiable?
Should there be an online service for this? Maybe a flash app?
Need some directions...
Thx
Paulo Bueno.

There are likely more available as well.

I have purchased a simple biometric fingerprint reader that is usually used for laptop security through a USB connection. It is just called biomentric finger print reader, not branded! It came with the software for creating security for laptop, and it works great.
However, I had a different idea for it: I am intending to create a database of users fingerprints so that I can identify which user swiped their fingers on it, ie, to use it for different users' authentication using fingerprints. I don't seem to be making any head or tail on how to go about that.
I would like to find out if there is other kind of software to install that will make this gadget print the fingerprint or a code to say a spreadsheet or database whenever I swipe a finger on it? I was thinking it would be a simple as when I use a bar code scanner to print codes of various items to a spreadsheet.
Could someone please advise how to go about this. I believe it should do that but I just dont know where to start.
thanks.
As an alternative wrapper to WinBioNET as mentioned by Robinicks there is WinBiometric.Net.
Disclaimer: I do not own this project.
It has a really nice test project for playing around with the different API functions available in the Windows Wiometric Framework. This test project was monumental in helping me understand the Windows Biometric Framework.
The WinBiometric.Net wrapper has a claim of 100% API coverage, a NuGet package and has the MIT license.
I found it to generally have a very high quality of code as well.
As for storing the fingerprints in a database you could use the WinBioCaptureSample API function to capture a sample, which can then be stored in a database.
The sample can be converted into an image as well, there is a nice example of this in the wrapper.
I know this is an old question but I figured I'd post anyway.
You can use the WBF (Windows biometric Framework) API that is free, but you must first verify if your biometric device is WBF compatible. The documentation and samples for WBF are for C++, but there is a wrapper sample in C# that you can download here: Cirrostrata biometrics Regarding how to convert the scanned data into an image, you can check this post: How to convert winbio data into image. Hope this helps to start.
You can use the WinBioNET .NET wrapper for Windows Biometric Framework (WBF). It has a demo winforms app in the solution. Just open it up, select the demo app as the "startup project" and run. If you have any devices connected it will enumerate it at startup.
I downloaded Veridis Biometrics SDK for my Futronic FS80 device, how can I capture finger print and save it to my SQL Server database? I know it is very basic but I am new with fingerprint device, I spent much time looking for some tutorials but i failed. Thanks In Advance evryone.
Look at the samples folder. The samples are very straight forward to use. You might also want to look through their manual here.
I used the SDK for a project but implemented with Java.
I am developing an iPad application where in there is a requirement that application should be able to print using any WiFi Printer even though it does not support AirPrint.
I need to do it without the use of AirPrint and AirPrint Hactivator.
I have referred to almost all questions on StackOverflow but none did seem to help.
I have seen a sample application which is on app store and which implements this.
Printing for iPad By Ndili Technologies, Inc.
What are my options to make this work?
Thanks
I found this API/SDK, which I haven't used, but looks promising :

I don't think there is any way of doing this. As far as I know Apple will not let you install printer drivers on the iDevice. And even if you could you would have to get all of them yourself (there are a lot and you would likely miss some). And then you would have to find a way to implement all of them so that they would work. If you have found a way to do this, then kudos to you, but I do not know of any App Store developer that has accomplished this yet, and I doubt it is possible.
I think you could develop some sort of system that relies on connecting to a service on computer that has a printer. When apple originally Released the beta of AirPrint you could send a print to iTunes and then it would send it to the printer.
The Print n Share Pro (product page, iTunes) app has drivers for most WiFi printers and print email/webpages & files etc. direct without a computer. They also have an API to allow other apps to print using their app but you will need to contact them about that.
I am getting familiar with Google Sites. What I want is, building a Site front-end for a Google Spreadsheet.
I want to Display data from the Spreadsheet in the Google Site, later maybe some graphics as well. To my knowledge there are two ways to accomplish this, Apps Scripts and Gadgets. Building a Gadget seemed much more easy in the beginning, however gives me some trouble. After reading more about Apps Scripts I finally found a way to access the Spreadsheet and display data.
But reading a lot of google documentation, I wonder what really is the difference? In what cases should one use Gadgets and in what case Apps Scripts?
Maybe I am just a little overwhelmed but it would be nice to get some feedback from experiences developers in that field!
Thanks a lot.
Cheers,
Daniel
Google Apps Script is javascript, but run in server side. So it is not client side javascript like javascript Gadget or any HTML.
Google Apps Script use GWT, which generate client side Javascript.
Gadget is XML code containing HTML inside
which means gadget is text.
Google Apps Script is kinda JavaScript
which means GAS is code.
Might be the main difference.
Would a script that sets display messages for instant messengers be simple or complex? After some searching, there doesn't seem to be any information about this at all.
For the sake of an example, if I had a text file of quotations, would it be possible to have the google talk display message change to a different quotation hourly?
Depends on which client you're using. As far as I know, Google's client doesn't offer any interface for plugins, but the open source instant messenger Pidgin does. I think there already is a plugin for what you want to do, but you can write your own using the documentation and examples they give you.
The complexity of writing something like this is based on how much C or Perl you know, since you can program in either of those for Pidgin. Reading code from other people's plugins, you should be able to figure out the Pidgin API.
You can use Kik API to programmatically send rich content and files between mobile applications. It is available for iPhone and Android platforms and takes only about 5 lines of code to integrate into your app. There is more info at the API website: http://www.kik.com/dev
