I am trying to develop an application on class attendance using fingerprint. Through rigorous research, I found out that I can use 'flexcodesdk' for my Vb.net program.
But the issue is that for every fingerprint scanner (Digitalpersona) there is needed to register it on flexcodesdk site to get series of API keys. What am I going to do about this issue because once I change the fingerprint scanner of similar product, it will complain of registration invalid.
Many developer develop applications an any body can use different scanner regardless of the serial number.
Help me out gurus in the house.
It appears that their FAQ states that each license is tied to a specific device.
How many devices that can be used in one FlexCode SDK license ?
Only the device that you submitted the registration number.
This means that each new device needs to be registered into their system in order to provide you with a new license for their SDK.
This seems quite a restricting model.
Perhaps you might want to consider the free and open source c# implementation at https://www.codeproject.com/Articles/97590/A-Framework-in-C-for-Fingerprint-Verification
I have successfully created multiple applications using this framework.

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 am not a professional developer but I want to develop one project that includes sending message through mobile connected through USB port only... And if possible I want to keep it generalized, like no need for handset model and service provider name.
I don't think it's possible to do this. Certainly at the very least it would depend on the model of mobile in use.
However as an alternative approach there are companies that provide a (paid for, but not expensive) SMS service accessible via a web API. This may suit what you are trying to achieve.
I don't think you will find this easy. Messages can be sent in 2 different modes 'text' or PDU. Support for both modes is not universal across all phones. PDU is the most widely available type on modern phones, but is also the most complex. Not all mobile phones expose a modem to the computer eg. Windows mobile 6.*. Many phones use proprietory software that does not support all commands. Different phones will connect to different COM ports so this will need checking every time, and could prove tricky if there is more than one phone/modem connected. However using just one phone and sending messages in text format after configuring the settings manually the first time is very easy.
See an example here http://www.codeproject.com/Articles/34360/vb-net-AT-commands-to-send-SMS
I am developing a device firmware based on an LPC17XX+FreeRTOS. My development environment is Eclipse + GCC, codes are in C. The requirement of the end product is:
A "base firmware" running RTOS and performing some periodic task (eg. perform health check).
The base firmware needs to support an API which will have some functions for data manipulation/delay/timing and some functions for using the device ports and I/O.
The user can build their own app using this API.
The user app needs to reside in an empty space of the flash. (It will be sent to the device via Serial port and I plan to use IAP to save it on flash)
I want to start the app as a new task from the "base firmware".
Step 1 and 3 are fairly easy to implement. I am not sure what is the best way to implement 2,3 and 4. So far I've looked at Dynamic linking, jump tables, overlays etc and I am kind of lost. Can someone give me an overview of proper implementation steps?
Some related questions:
Any other way to develop firmware for a product which provide API based App/module development and loading?
What do I need to provide to the user for using the API? Will my API source code be open?
I am open to any ideas, thanks :)
I am developing software which I want to sell online. The typical pay the vender, get a digital key that unlocks the application scenario.
I've never set this up before, does anyone have any info on good service providers, and things I need to know when setting this up?
Microsoft uses digital river, maybe check them out?
You can checkout a typical license acquisition flow using FastSpring
FastSpring / NetLicensing flow
This combines FastSpring e-Commerce and NetLicensing license management.
You did not say what language you are planning on using, but this is a great solution for a .net compiled language:
http://xheo.com/products/copy-protection
It provides two key features. First the ability to automatically generate your licenses based on many different ecommerce solutions so you don't have to keep paying a 3rd party a % for it. Second, it offers code protection to prevent people from using Reflection on your software to crack it / steal your intellectual rights. (note i said prevent, not completely stop)
I'm using FastSpring, you give them binary file and keys, and you setup your account to send an email that contains these two informations. you can tell them what you want and they will do it for you
I'm working on an order entry application targeted to windows mobile devices.
I need to be able to send and receive emails from within the application, but without using pocket outlook (this is a customer requirement).
I see that the .net mail classes are not available for the compact framework. So I need to look elsewhere.
I found 2 interesting libraries: CSLMail and MooseWorks' Email Controls. But none is able to deal with SSL connections, and this is a mandatory requirement
I've found a few commercial email component suites supporting the compact framework, but their price is very high ($200+).
I guess I'm not the only one having the problem of sending and receiving emails - so, my question is: can anyone suggest me any free or low cost cf.net smtp/pop3 library?
Thanks
First, I'll say that when you look at the cost of your time, $200 is a whole lot cheaper than writing it yourself, and it's a small price to pay for something that is done and tested.
On the free side, there is the Smart Device Framework, which contains the OpenNETCF.Net.Mail namespace, which does do SMTP. Still, you're on your own for SSL.
Well, I think ctacke said everything there is to say.....however:
What regards SSL, there is a free component that works on Windows Mobile (and CF.Net) which is called SocketPro (written by Udaparts). You may find further information on this page (from where you can also download it). Have a look also at their forum where you can find examples.
I have successfully used this library in a small application of mine connecting to mail-servers that require SSL. The only exception is GMail which for some strange reasons the SocketPro-library has difficulties to communicate with. However, for GMail I used a version of OpenSSL which I found floating around on the internet which works well with GMail and CF.Net although it is a bit big in size.
Once you have established a connection with your mail-server, you can use ordinary POP3 for retrieving e-mails and SMTP for sending them.
Edit: I should mention that if your e-mails have attachments, then you need to look into MIME as well but that's another story. However, there are free libraries with source-code which can be found on the internet (try CodeProject).
Hope it helps...
OpenNetCF is definitively worth checking. As for commercial components - $200 for the tested and supported code would be probably cheaper than trying to roll out your own implementation or than trying to use some downloaded proof-of-concept code in production environment. Sometimes it's nice to have someone who is paid for solving your problems, anyway.
If you start evaluating commercial components you can try to check our Rebex Secure POP3 as well. It does support both SMTP/SSL, POP3/SSL and S/MIME on .NET Compact Framework. It costs a bit more that $200, though.
