3.8. How do I include SQL Server CE with my application installation?
To install SQL Server CE with an application, simply install the proper SQL Server CE CAB files as part of the application's installation. There are two sets of cabs associated with SQL Server CE.
The developer CAB includes Query Analyzer, and error strings. This CAB should not be included with application deployment. It comes in two actual files, one for Pocket PC and one for Windows CE 4.x devices:
sqlce.dev.ppc3.<processor>.cab
sqlce.dev.wce4.<processor>.cab
The SQL Server CE CAB, which includes the engine, client agent, and managed extensions for the client agent is required by applications utilizing System.Data.SqlServerCe components. This CAB also comes in two actual files, one for Pocket PC and one for Windows CE 4.x devices:
sqlce.ppc3.<processor>.cab
sqlce.wce4.<processor>.cab
Applications that access SQL Server, ie applications utilizing System.Data.SqlClient components should deploy the 'sql' CAB. This CAB also comes in two actual files, one for Pocket PC and one for Windows CE 4.x devices:
sql.ppc3.<processor>.cab
sql.wce4.<processor>.cab
All of these CABs are included in the Visual Studio .NET 2003 Professional Edtion install. The default location is:
\Program Files\Microsoft Visual Studio .NET 2003\CompactFrameworkSDK\v1.0.5000\Windows CE\...
3.9. How do I use GAPI to create a graphics engine?
This article describes how to create a DLL that wraps GAPI (Game API), such that it is .NET Compact Framework compliant, and use it to create and optimize a basic graphics library in managed code.

This article expands upon the "Dancing Rectangles" sample by implementing loading and displaying of bitmaps. It also implements some more advanced features such as animated bitmaps, source and destination key transparency, and alpha blending, i.e., translucency.

This article expands upon the "Dancing Zombies" sample by implementing drawing of points, lines, and custom 1 bit fonts converted from 8 bit bitmaps. It also implements an input system that overrides the functionality of the hardware buttons and tracks button states.

4. 图形用户界面(GUI): 窗体
4.1. 怎样建立一个全屏的窗体？
您必须把WindowState属性设置为最大化。做一个看不见的窗体，如把全屏的图片放到窗体中，您需要把FormBorderStyle设置为None，关掉ControlBox删掉窗体中所有的菜单。
//C#
this.WindowState = FormWindowState.Maximized;
this.FormBorderStyle = FormBorderStyle.None;
this.ControlBox = false;
this.Menu = null;
'VB
Me.WindowState = FormWindowState.Maximized
Me.FormBorderStyle = FormBorderStyle.None
Me.ControlBox = False
Me.Menu = Nothing
4.2. 什么时候用窗体的构造器？什么时候用窗体的Load事件？
窗体的load功能是做界面操作的最好方法。典型又安全的做法是在构造器中创建数据和控件的实例。任何包含用户界面的控件或窗体的初始化，都应该在load功能中完成。例如：在窗体的构造器中完成控件对象的建立，然后在load功能中设置控件的位置等 是安全的做法。
4.3. 怎样把最小化按钮换成关闭按钮？
通过开发环境的设计器，可以把窗体的自动最小化模式转变成关闭模式，或者通过变成实现。(x)按钮自动最小化应用程序，(ok)按钮回关闭程序。
在设计器中转化窗体的风格
打开Visual Studio环境的窗体设计器，查看属性。在窗体上右键并选择Properties，在Window Style 部分把MinimizeBox设置为 False。
在代码中转变窗体风格
简单的在窗体的load功能中添加以下一行代码：
//C#
this.MinimizeBox = false;
'VB
Me.MinimizeBox = False
