thanks
but the problem is i need to extract the template from the fingerprint each time i need to identify someone
and that takes 45 second depend on the database for me this to slow
my problem is with passing the database values
for exemple
List<datarow> dtrows = dt.asEnumerable;
and then convert each datarows to bitmaps
and then convert pass the list of bitmaps to a list of fingerprints
and then pass the fingerprints to the persons
for exemple
person.fingerprints = fingerprints;

and then extract each fingerprint passed to the person with the Afis.extract(person) function
and then instead of using afis.identify function i use afis.verify which is toooo slow and i cant get afis.identify to work

AGAIN, your BEST source of information is to ask the people who wrote the library. NOT a bunch of people who have never used it, let alone heard of it.

If you don't get an answer then it means that no one has the answer. Reposting the same question is not the way to go about it. Try editing the original and adding some more detail about your problem.

Use the best guess

..and which protocol did you have in mind? "Anything" but TCPIP?

What's wrong with using sockets? In a wifi-network, I'd expect people to use a network-protocol, and TCPIP would usually work with sockets.

Then again, you "could" create webservices and communicate using those. It'd just be a bit overhead.

This shows that you don't know what WiFi really is. It's a wireless Ethernet interface. It's a carrier or transmitter and receiver of other transport protocols, not an implementation of one. You cannot transmit a file using WiFi.

You have to use an application protocol, like FTP, HTTP, or even a protocol of your own design, transported via another protocol, like TCP/IP, to communicate with another device or computer. Look at what TCP/IP stands for: Transmission Control Protocol/Internet Protocol. It's a transport protocol, not an application protocol.

how to control LEDS

how do you control LEDs in C#

Marco Bertschi21-Feb-13 21:59

It depends on how the LEDs are connected to your computer. Can you give more detailed information?

i would like to connect the LEDs by USB.
thanx

Is the USB going to be recognized as Serial Port on your computer?

yes...it will...though I have been doing some research and I think a DB25 serial connector will be easier to work with if I use an IC with Darlington pair arrays to interface the PC port and the LEDs.
I now need references.
any help will be highly appreciated.

For how to send commands though a serial inteface I only can refer to one of my article[^]s becausee I have not much expeience with hardware programming. Maybe the manual of the DB25 connector gives you some information.
If you want other opinions you may should ask about experiences with the DB25 connector and the IC you want to use in the Hardware & Device forum[^].

Considering todays machines are not even coming with serial and parallel ports, you're entire premise of using them is already dead in the water and limited in scope to the lifttime of the hardware that you are currently using.

Since you already know a bit of eletronics, just go with a microcontroller that can run the .NET Micro Framework and be done with it!

Oh! and those can already be programmed over USB using Visual Studio 2008 and up, if not VS2010 and up.

how do you control LEDs in C#

That already implied that you imagined that one can hook 'em up easily to an existing port. You'd either dive into Windows 7 "sensor api", or look at an external board.

Go for a Raspberry Pi if you're unsure, it has a GPIO-port and there are some samples to get you started on your own project.

By writing appropriate code for what you want to do.

What did you think the answer was going to be with a question like that??

In all seriousness, if you want to use C#, get a Netduino[^] or a FEZ Panda[^] microcontroller and learn how it's really done, without risking your computers expensive hardware. You'll also learn alot about digital electronics if you really want to teach yourself. Try getting this book[^] or this one[^].

it depends on what you need , if you have a Com ports you can use it easily with some hardware buffer and amplifier , or you can use any controllers, if you are not familiar with Arduino or PI , try to find a CanaKit board, its very easy and with LED's and Relayed output.
