解决方案

你好slwa.

在MSDN上有两个很好的资源.它们都比较老，但是编程概念仍然适用.但是，我会以他们对电子签名和法律的说法为过时的材料.

数字墨水签名-概念和技术( http://msdn.microsoft. com/en-us/library/ms812501.aspx ).是一个很好的概述，讨论了如何使用基本墨水控件 平板电脑平台来读取和存储签名.示例中有一些代码，但是主要是概念性材料，带有指向参考页的指针.

创建用户控件以在Tablet PC上捕获签名( http://msdn.microsoft.com/en-us/library/aa480678.aspx )提供了用于收集nad的控件和代码示例 渲染墨水签名.代码示例( http://www.microsoft.com/download /en/details.aspx?displaylang=en&id=874 )是为Visual Studio 2005创建的， 因此要进行编译，您必须进行一些更新.但是您可以查看示例以了解所有内容.

希望这会有所帮助，

Hello slwa.

There a re two good resources on MSDN. They's both a little older, but the programming concepts still apply. I would take what they say about E-signatures and the law as out of date material, however.

Digital Ink Signatures - Concepts and Technologies (http://msdn.microsoft.com/en-us/library/ms812501.aspx). Is a good overview that talks about how to use the basic ink controls of the tablet platform to read and store signatures. There's a little code in an example, but it's mostly the conceptual material with pointers to the reference pages.

Creating a User Control to Capture Signatures on a Tablet PC (http://msdn.microsoft.com/en-us/library/aa480678.aspx) offers a control and code examples for collecting nad rendering ink signatures. The code sample (http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=874) was created for Visual Studio 2005, so to compile it, you'll have to make some updates. But you can look at the sample to see how everything is plumbed.

Hope this helps,

Eliot
