今天在看Windows Mobile Team Blog的时候，看到关于SDK, DTK, DRK的文章，通过阅读，简单的了解一些。所以也和大家分享一下。

SDK: Software Development Kit
We have not released a new SDK for Windows Mobile 6.5. The Windows Mobile 6 Professional SDK or Windows Mobile 6 Standard SDK are required for Windows Mobile 6.5 application development.

6.5 依然沿用了Windows Mobile 6 的SDK。

DTK: Developer Toolkit
The Windows Mobile 6.5 Developer Toolkit (DTK) is not an SDK! The DTK contains emulators, gesture APIs, and samples useful for developing Windows Mobile 6.5 applications. You will still need to install Visual Studio and the Windows Mobile 6 SDK prior to running the toolkit installer.

6.5发布了一个开发包，下载地址是

其中有了简体中文的模拟器。
在机子上安装了一下，界面效果比原来好看许多，但是改动让我有一些不熟悉。

里面增加了几个头文件：
<gesture.h>
<GesturePhysicsEngine.h>
<WindowAutoGesture.h>

还有几个附带的例子。

DRK: Developer Resource Kit

The Windows Mobile Developer Resource Kit (DRK) is an offline DVD copy of the most useful and relevant Windows Mobile application development tools and resources. Traditionally the DRK does not contain any exclusive content, in that nearly everything on the DRK is available for download online. This time we are pleased to publish the Windows Mobile 6.5 DRK with several sample chapters of Microsoft Mobile Development Handbook from Microsoft Press (Wigley, Moth, and Foot).

这个词是我第一次听说。没有下过。
