1.打开VC2008，新建基于对话框工程，名称： MyXmlViewer；
2.在对话框上放置一个RichEdit 2.0控件，ID号改为： IDC_RICHEDIT_XML，设置其Multiline属性、Horizontal Scroll属性、Vertical Scroll属性、Want Return属性；
3.在应用程序类实现文件，添加以下代码：
| 1 |
|
AfxInitRichEdit2(); |
4.包含"kofxmlricheditctrl.h"头文件，然后关联IDC_RICHEDIT_XML的变量即可，如下：
| 01 02 03 04 05 06 07 08 09 10 11 12 13 14 |
|
#include"kofxmlricheditctrl.h" classCMyXmlViewerDlg:publicCDialog { //... public: CKofXMLRichEditCtrlm_RichEdit; }; voidCMyXmlViewerDlg::DoDataExchange(CDataExchange*pDX) { CDialog::DoDataExchange(pDX); DDX_Control(pDX,IDC_RICHEDIT_XML,m_RichEdit); } |
5.效果如下所示：
