i want to implement a REST web service
|

A REST webservice and a MS web service is 2 different things.
Look in writing you own IHttpHandler instead.

Hi Everybody,
I have a problem (for me than  that i do not now how to do the following.
I have a usercontrol with on it a listview control. This usercontrol is placed on a standard winform. Now i want on the form react on a event of the listview control. In other words. I the listview is clicked i want to catch the event en do something with the selected record.
I can set the on click event in the usercontrol but that will not show up in my form. I have tried something with override on click events but cannot get the hang of it.
Any examples, suggestions.
Thanks
Kind regards,

Hy,
I have a usercontrol with on it a listview control. This usercontrol is placed on a standard winform. Now i want on the form react on a event of the listview control. In other words. I the listview is clicked i want to catch the event en do something with the selected record.
Why would you react in your Form? Handle the Events in your Usercontrol.
I can set the on click event in the usercontrol but that will not show up in my form. I have tried something with override on click events but cannot get the hang of it.
The event will be fired, if the usercontrol itself is clicked for example. If you want to catch the event on the listview, you have to publish an event for that in your usercontrol and forward the onclick event of your ListView. For Example:
MyUserControl.OnListViewClicked += new someeventhandler(handler)
Hope this helps

Hi Vikas,
If you are looking to compare the images as graphs, these are compared pixel by pixel method. Please refer to the below mentioned link for more information:

If it is in regards to comparing human faces, please refer to the below mentioned links:

A Timer.
Despite everything, the person most likely to be fooling you next is yourself.

TimerCallBack delegate can be used for this.

Anybody know how to fetch the fingerprint from fingerprintreader and it's verification........
But i don't want to use such a things like Microsoft SDK's and all...
|
|
|
|
|
So what do you want to use? You want to write the whole thing yourself? Good Luck!!

i actually do that for my company...
the fingerprint scanners we use are manufactured by ZK, and its an "offline" device, which means the person "clocks" but the time stamp is kept on the device until a computer "polls" all the time stamps, saves them, then deletes them off the device.
to do all this i use the manufacturers SDK & dotNet wrapper.
are you trying to get data off an "offline" device, or one of those small usb finger print scanners?

Thank u Harvery,
I just tried out using that small fingerprint reader which is connected to our USP port...
could u plz me that u are used any algorithms to fetch fingerprints are else any concept wise programs....
if know any URL to related to this means just post me to it......
Once again Thank u for ur reply.....

you'll definitely HAVE TO use the manufacturers SDK...
... unless you want to scan the USB port and somehow by trail and error compare what you send and what you receive in response. and i know this does not work very well. one of my co workers used to do that and it takes months!!!
i know those little finger print scanners, thats an "online" model. what it will do is just send a fingerprint-template* to the computer its connected too. your program will then have to catch the event, compare the fingerprint to a database of sorts and decide if the person should get access to what ever its for or not.
*finger print template = the device takes the image of your fingerprint and converts it to either a STRING template(which looks like garbage characters) or a byte array
trust me, if you really want to use that finger print scanner get the SDK and use it. if you for some reason can't, in my humble opinion, don't even bother trying.
good luck!

Hi,
Thank u Harvey,
I just finished that verification and takeout the fingerprint Template use of that FingerPrint_SDK_2007....
I stored that Fingerprint Template in SQL2005 as a image data type using that BYTE conversion
here my Question is... if I stored more than 1,00,000 Template means the Sql will get slow to get a data or not?

that depends on you database design my friend
if you have primary keys and indexes on the right places SQL souldnt get slow. it was built to handle alot of stress

Hi friends,
I am new for finger print device
Let u know one think that i am using visual studio 2008 and i have a database in as dbf files.
I have one fingerprint device LAN based and also USB based
I have one web application , i want to use a fingerprint device as requirement
Now my question is:
I just write a code on page load as below
int count = 0;
zkemkeeper.CZKEMClass axczkem1 = new zkemkeeper.CZKEMClass();
bool bIsConnected = false;
string ip = "192.168.140.254";//write here IP Address of your biomatric m/c
int port = 4370;
bIsConnected = axczkem1.Connect_Net(ip, port);
if (bIsConnected == true)
{
MessageBox.Show("Connection established!!!" );
bool ret = axczkem1.ReadAllGLogData(1);
if (ret)
{
int a = 0;
int b = 0;
int c = 0;
int d = 0;
int ee = 0;
int f = 0;
int g = 0;
int h = 0;
int i = 0;
int j = 0;
int k = 0;
int l = 0;
int m = 0;
int n = 0;
int o = 0;
while (axczkem1.GetAllGLogData (1, ref a, ref b, ref c, ref k, ref l, ref d, ref m, ref ee, ref f, ref g))
{
if (ee == 7 && m == 4 && d == 2011)
{
count++;
if (b == //any Employee No)
{
MessageBox.Show(b.ToString() + " hour: " + f + " Min: " + g);
MessageBox.Show(k.ToString() + " " + l.ToString());
}
}
}
//MessageBox.Show(count.ToString ());
}
}
else
MessageBox.Show("cannot Connection!!!");
axczkem1.Disconnect();
this code is of window application but i just replace it with web, i get here that connection status.
I want to know that how to catch the event that a finger is put on device that send device.
i have to refresh the page every time when a any finger is put on device
I hope any one understan what i want to say, please any one help me
And one more think am i going right way or wrong.

You may use the UDP protocol to achieve this.
UDP can broadcast as well as multicast your messages.
If required, you may use both of these options in your application.
Just start browsing for the underlying Sockets in MSDN and you will create a nice applicaiton!!!
