给CuteEditor5增加了高亮代码显示功能(C#版)

CuteEditor在很多网站上都有介绍了，是一款超级Cool的web在线编辑器,下载地址用google找一下就能找到，就不提供了，但是安装方法还是要说一下，因本次是使用vs2005。
      我们在vs2005里面新建个web site吧，把CuteEditor.dll（主控件）、CuteEditor.lic（许可证）、CuteEditor.ImageEditor.dll（因为5.0增加了个EditorImage的功能）、NetSpell.SpellChecker.dll(拷这个的原因是默认打开拼写检查)这几个文件拷贝到web site的bin目录下，刷新bin目录（不像vs2003需要引用dll），同时我们也要把解压缩后的CuteSoft_Client目录全部拷贝到应用程序的根目录下。然后把CuteEditor添加到工具面板.我们在工具面板里面右键选择"选择项",在出来的对话框里面选择"游览",找到CuteEditor.dll,一路确定就可以了。

      我们再添加个CuteEditor.aspx,把工具面板里面的Editor拖到页面上来，这时你就可以运行你的程序使用CuteEditor了，运行如下图：

      上面的只是个最简单的安装,还有比如控制CueEditor的显示,已经安全性和那个什么上传的啊,还有控制用户上传的目录啊,或者给每个用户建个他们自己的图片目录啊,还必须要另外设置，这些暂时先略过吧，您可以自己看一下说明进行设置，这里不多说了。我们现在要开始要给CuteEditor增加高亮代码显示功能，俺这里使用的是CodeHighlighter控件，您可以到http://www.codehighlighter.com/下载最新版，最新版同时支持.net1和.net2，因为使用的是vs2005，俺就使用了最新版，现在我们先来给CuteEditor增加一个按钮和打开插入高亮代码的页面代码。

CuteEditor.aspx代码

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="testCuteeditor._Default" %>
<%@ Register Assembly="CuteEditor" Namespace="CuteEditor" TagPrefix="CE" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>无标题页</title>
</head>
<body>
    <form id="form1" runat="server">
    <script language="JavaScript" type="text/javascript" >
function ShowMyDialog(button)
{
//use CuteEditor_GetEditor(elementinsidetheEditor) to get the cute editor instance
var editor=CuteEditor_GetEditor(button);
//show the dialog page , and pass the editor as newwin.dialogArguments
var newwin=showModelessDialog("insertcode.aspx?_rand="+new Date().getTime()
,editor,"dialogWidth:600px;dialogHeight:430px");
}
</script>
    <div>
    <CE:Editor ID="cuteedit" runat="server" AutoConfigure="Simple">
        <FrameStyle BackColor="White" BorderColor="#DDDDDD" BorderStyle="Solid" BorderWidth="1px"
            CssClass="CuteEditorFrame" Height="100%" Width="100%" />
    </CE:Editor>
    </div>
    </form>
</body>
</html>

CuteEditor.aspx.cs代码

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

namespace testCuteeditor
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            int pos = cuteedit.ToolControls.IndexOf("Italic") + 20;
            System.Web.UI.WebControls.WebControl ctrl = cuteedit.CreateCommandButton("myinsertbutton", "csharp.gif", "插入代码");
            ctrl.Attributes.Add("onclick", "ShowMyDialog(this)");
            cuteedit.InsertToolControl(pos, "myinsertbutton", ctrl);
        }
    }
}

运行如下图：

工具栏中多了一个按钮，接下来把codehighlighter的dll控件也按刚才的方法copy到bin目录下，再把Languages目录拷贝到应用程序根目录下，这里还要对web.config进行配置一下，在<configuration>的<configSections>下增加一句：

<section name="codeHighlighter" type="ActiproSoftware.CodeHighlighter.CodeHighlighterConfigurationSectionHandler, ActiproSoftware.CodeHighlighter.Net20" />

在<configuration>和</configuration>间加

<codeHighlighter>
<cache languageTimeout="3" />
<keywordLinking enabled="true" target="_blank" defaultKeywordCollectionKey="ActiproKeywords">
<keywordCollection key="ActiproKeywords">
<explicitKeyword tokenKey="IdentifierToken" patternValue="Actipro" url="http://www.actiprosoftware.com" caseSensitive="false" />

</languages>
<lineNumberMargin foreColor="Teal" paddingCharacter=" " visible="true" />

<spacesInTabs count="4" />
</codeHighlighter>

建立InsertCode.aspx文件（代码高亮处理）代码如下：

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="InsertCode.aspx.cs" ValidateRequest="false" Inherits="testCuteeditor.InsertCode" %>

<%@ Register TagPrefix="CH" Namespace="ActiproSoftware.CodeHighlighter" Assembly="ActiproSoftware.CodeHighlighter.Net20" %>
