我相信你早些时候提过这个问题，我在那里回答你。 MOSTLY，供应商为您提供可用于为特定设备编写自己的应用程序的SDK，我也为您的设备发送了SDK的下载链接。为什么不下载该SDK并检查其中的示例代码？
I believe you have asked this question earlier and I answered you there. MOSTLY, vendor provides you SDK that you can use to program your own application for that specific device, I sent you download link of SDK for your device also. Why don't you download that SDK and check sample code in there?
指纹设备需要COM CONTROL。
使用Add Refrence向导在页面上添加它。
最后使用它可以在服务器端编写和执行代码。
在网页上使用对象标签
< object id =idofobjectclassid =CLSID：class_Id_of_com_control>
name =naemofobjecte>
< / object>
下载sdk表格

安装sdk后，它会给出pdf和示例演示项目。
It require "COM CONTROL" of finger print device.
Add it on page by using "Add Refrence" wizard.
finally by using it name you can write and execute code on server side.
Use object tag on web page
<object id="idofobject" classid="CLSID:class_Id_of_com_control">
name="naemofobjecte">
</object>
down load sdk form

after install sdk it give the pdf and sample demo project.
我很惊讶人们常问这个问题。很明显，任何提出这个问题的人都不知道ASP.NET是什么，或者它做了什么。它是HTML和JavaScript的引擎。这就是您的浏览器知道如何使用的。所以，你做不到。您可以用C ++或.NET控件编写ActiveX控件（这意味着您的用户需要安装.NET），或者现在可能使用Silverlight（我不确定Silverlight是否可以访问USB端口，Silverlight 4添加了打印功能第一次 ）。然后，您可以将其用于指纹扫描，并编写代码以在其与您的网页之间进行交互。假设用户将授予您的控制权限，但我认为指纹扫描程序将用于不会出现问题的封闭应用程序。
I'm astounded how often people ask this. It's clear that anyone who asks this has no idea what ASP.NET is, or what it does. It's an engine for HTML and javascript. That's what your browser knows how to work with. So, you can't. You could perhaps write an ActiveX control in C++ or an .NET control ( which means your user needs .NET installed ), or potentially nowadays use Silverlight ( I am not sure if Silverlight has access to the USB ports tho, Silverlight 4 adds printing for the first time ). Then you can use that for fingerprint scanning, and write code to interact between that and your web pages. Assuming that the user will give your control permission to run, but I assume a fingerprint scanner will be used in closed applications where that won't be an issue.
