pleas help it''s urgent
thanks in advance(^_^)

推荐答案

我如何将传感器(ZK 7000)连接到我的项目?

指纹扫描仪始终带有SDK.如果您的扫描仪没有一个，则需要联系扫描仪的制造商并获取它.

我如何在sqlserver2005中存储指纹图像以及哪种数据类型?

你不这样做.指纹认证系统为您处理后端数据库.指纹ID不会存储为图像，而会存储为数据.

我如何记录指纹图像的验证和识别时间?

该数据应与用于存储指纹的数据库分开存储.跟踪尝试的身份验证是一项单独的功能.如果您真的不知道如何使用DataTime.Now()或将记录写入数据库，那么您的技能就有很大的空缺.

how can i connect my sensor (ZK 7000) to my project ?

Fingerprint scanners always come with an SDK. If you don''t have one for your scanner, you need to contact the manufacturer of your scanner and get it.

how i can store the fingerprint images in sqlserver2005 and in which data type?

You don''t do this. Fingerprint authentication systems handle the backend database for you. Fingerprint IDs are not stored as images, but data.

how i can record the time of verifing and idintification of the fingerprint image?

This data should be stored seperately from the database used to store fingerprints. Tracking attempted authentications is a seperate function all together. If you seriously have no idea how to use DataTime.Now() or write a record to a database, you''ve got a huge hole in your skill set.

1)您应该与创建它的人交谈- http://www.griaulebiometrics.com/page/en-us/tutorial [ ^ ]-他们应提供技术支持支持，并将比我们更了解他们的产品.如果他们不这样做，那么请寻找其他供应商并要求您退款！
2)参见(1)
3)进行验证时获取当前日期和时间:

1) You should talk to the people who created it - http://www.griaulebiometrics.com/page/en-us/tutorial[^] - they should provide technical support and will know more about their product than we will. If they don''t, then find another supplier and demand your money back!
2) See (1)
3) Grab the current date and time when you do the verification:

DateTime now = DateTime.Now;

，并使用此时间戳在数据库中插入新记录(或更新现有记录).

此过程的哪一部分给您带来困难?

and insert a new record (or update an existing record) in teh database with this time stamp.

Which part of this process is giving you difficulties?

谢谢您提供的所有链接对我有用，实际上我想在另一个系统之前进行身份验证系统(例如学生出勤系统)那是我要记录学生出勤系统的时间.如果有人对如何链接两个系统有任何想法，请帮助我吗?

thank you all the link which you provide was usefule to me , actully i want to do the authentication system in front of another system(For example Student Attendence system) thats whay i want to record the time at which student come in or out of attendance system. if any one has an idea about how to link the two systems , please help me ?
