I have to program that, we handling with attendance management.we using RFID cards to enroll their attendance. My question is , When any one swap their card in RFID machine, their details of time and date stored in dB. My projects is to print that information in a small paper (thermal printing) to conform their attendance.
the program should be in VB.Net
I hope the question is understantable..
pls anyone give your solution for my question..

First you have to got a RFID SDK and is usually attached with RFID devices that you've bought.
In the SDK there must be instructions on how to capture the data and the status of RFID. Subsequently followed by data storage and printing

Looking to create a voice application to work with 10 computers and 1 server connected locally.(offline) I'm thinking the server would hold the application and the computers would run clients.
Ideally there would be a total of 10 channels that users can join or leave.
I'm looking for open source applications or APIs that I can utilize for this. Are there any suggestions of prewritten code I can utilize and create a custom GUI?
I'm looking to create something similar to ventrillo but have the ability to customize the GUI.
You can use asterisk with app_conference or webrtc and some MCU.
But anyway you will not get even close to ventrillo. Ventrillo's main complexity is not conference itself, but noise supression/voice detection and choose of correct codec for each channel acordinly to current bandwidth.
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.
My company is trying to use Socket Mobile bluetooth scanner to scan the labels on product. I need to integrate this scanner with-in my iPad app so that when user scans a label , then scanned value comes to user's app and that value can be used for further processing.
Can someone help me in this that how can I integrate Socket Mobiles CHS with my iOS code? Company wants to decide for scanner to use or no.
You have two options HID and SDK
HID (aka quick and dirty)
Put your scanner in HID mode and it will behave like a bluetooth keyboard.
Pros
Scan into input fields in any existing app
Scan into the browser
No integration required
Cons
Limited ability for processing scanned data
No control over where scanned input goes
On screen keyboard doesn't auto-hide/appear
In HID mode, the scanner "types" data under the cursor. This means data can be scanned into the wrong field and the text input must be editable, so the user can modify the scanned value. You can configure the scanner to append a tab or return character to the scanned data.
HID mode is great for proof-of-concept type applications and is the only option for browser based applications at the moment.
SDK (aka doing it right)
Personally, I've never developed an iOS application using the SDK, so the best I can do is refer you to this create an iOS barcode scanner application video on youtube.
Pros
Total control over scanned data
Direct input to different fields based on pattern or barcode type
Prevent the user from editing the scanned data
Coerce the barcode into the desired format, before continuing
Take automatic action upon receipt of a scan
Cons
Not a turnkey solution for existing apps
Does not work in the browser

I want to be able to push messages out to certain customers who have a particular postcode. Is this possible with C2DM or is it a case of only pushing to everyone who has the application?.
It is not possible to determine the postcode of a device via C2DM. But you might use the
localization feature of Android and use this information to find the postcode.
Edit: Or just ask the user to enter his postcode ;)
Thus, your application needs to register at your server it could also submit the location information (in another step), and you could save it in your database along the device id.
Then you could send a message to all users that are in a specific area.
I'm trying to fix a bug with a site search function and have isolated it down to an issue with the FREETEXTTABLE function.
I have a the following query:
SELECT * FROM dbo.SiteContentForSearch INNER JOIN FREETEXTTABLE(SiteContentForSearch, sSearchText, 'NFC' ) AS SearchResultTable
ON dbo.SiteContentForSearch.liSearchID = SearchResultTable.[Key]
This is returning a rank of more than 0 for many of the rows which have 'NFC' present in the sSearchText column. However there is (at least) one row which it is returning a rank of o. It has the following text which as you can see contains NFC present a couple of times. Any idea's?

I'm currently having some FreeTextTable issues myself and the marked answer to this question:
Why or How does FREETEXTTABLE give a rank value higher then others
which contains this link
http://msdn.microsoft.com/en-us/library/ms345119%28SQL.90%29.aspx
explains how the FreeTextTable does its thing in maths. Particularly with reference to the OKAPI BM25 ranking formula.
Underneath the maths part is a section on issues with the ranking formula. Obviously its been 16 months since you asked this question but maybe this answer will help someone else with a similar problem. If you step through the problems and meta-problems with implementing the alogrithm you'll probably see where it could possibly be falling over.

EDIT: Also the answer to this question:
FREETEXTTABLE always has a rank of 0
includes this link
http://msdn.microsoft.com/en-us/library/ms142524.aspx
Which is a more approachable summary of the info about how the ranking formula works that is contained in the previous link.
