基于Visual Studio2010开发office2010办公自动化应用（9）自定义PowerPointAdd插件

PowerPointAdd插件是在播放幻灯片时伴随的小插件，随着企业办公的紧密合作，办公需求也出现个性化，多样化，office2010的出现迎合看此种需求，开发PowerPointAdd插件能让office2010 与程序智能地交互，也就是我们可以在PowerPoint里面嵌入我们的程序或者我们自己开发的适合自己需求的功能插件，以满足我们高效轻松的办公。

我们来演示一下在PowerPoint2010里面加入我们自定义的插件，比如加入一个五子棋游戏的小插件，在我们进行文档整理疲惫时适当娱乐轻松一下。

启动VS2010

创建一个PowerPointCSDN工程

创建后我们在工程里再添加一个名为"frm五子棋"的窗体，进入form页面加入如图所示的各种控件：

然后在frm五子棋.cs中加入下列代码：

最后在ThisAddIn.cs中写入如下代码：

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Xml.Linq; using PowerPoint = Microsoft.Office.Interop.PowerPoint; using Office = Microsoft.Office.Core; namespace PowerPointAddCSDN { public partial class ThisAddIn { private void ThisAddIn_Startup(object sender, System.EventArgs e) { frm五子棋 frm = new frm五子棋(); frm.Show(); } private void ThisAddIn_Shutdown(object sender, System.EventArgs e) { } #region VSTO generated code private void InternalStartup() { this.Startup += new System.EventHandler(ThisAddIn_Startup); this.Shutdown += new System.EventHandler(ThisAddIn_Shutdown); } #endregion } }

按下F5开始调试

运行界面如下，PowerPoint文档打开了以后，文档上浮着一个"五子棋"游戏插件：
