using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Microsoft.Office.Interop.Excel;
using System.Reflection;

namespace WindowsFormsApplication2

public partial class Form1 : Form

public Form1()

InitializeComponent();

public void Form1_Load(object sender, System.EventArgs e)



public void axWebBrowser1_NavigateComplete2(object sender, AxSHDocVw.DWebBrowserEvents2_NavigateComplete2Event e)

Object o = e.pDisp;
Object oDocument = o.GetType().InvokeMember("Document", BindingFlags.GetProperty, null, o, null);
Object oApplication = o.GetType().InvokeMember("Application", BindingFlags.GetProperty, null, oDocument, null);
Object oName = o.GetType().InvokeMember("Name", BindingFlags.GetProperty, null, oApplication, null);
Microsoft.Office.Interop.Excel.Application eApp = (Microsoft.Office.Interop.Excel.Application)oApplication;
MessageBox.Show("File opened by: " + oName.ToString());


private void axWebBrowser1_Enter(object sender, EventArgs e)

string strFileName = @"C:\Documents and Settings\yangyy\桌面\文件.xlsx";
Object missing = System.Reflection.Missing.Value;
axWebBrowser1.Navigate(strFileName, ref missing, ref missing, ref missing, ref missing);



怎样显示EXCEL的工具栏捏？

给点代码你参考
const uint KEYEVENTF_KEYDOWN = 0x0;
const uint KEYEVENTF_KEYUP = 0x2;
Object refmissing = Missing.Value;
object axWebBrowser;
//ExcelWrapper excel;
Excel.Workbook book;
Excel.Application app;
Excel.Sheets sheets;
Excel.Workbooks books;

string fileName;//输入文件名
public string FileName

get return fileName;
set fileName = value;


string sheetID;//单据号
public string SheetID

get return sheetID;
set sheetID = value;


string outFileName;//输出文件名
public string OutFileName

get return outFileName;
set outFileName = value;


bool readOnly;//输入文本
public bool ReadOnly

get return readOnly;
set readOnly = value;


string outText;//输出文本
public string OutText

get return outText;
set outText = value;


bool hasModify;//EXCEL是否修改
public bool HasModify

get return hasModify;
set hasModify = value;

显示EXCEL工具栏查看MenuControl方法 参考技术A 你的代码在我这里运行时，EXCEL是在本窗口的axWebBrowser1中打开的啊，并没有在另外窗口打开

可以用下面这句显示工具栏
axWebBrowser1.ExecWB(SHDocVw.OLECMDID.OLECMDID_HIDETOOLBARS, SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_DONTPROMPTUSER);

将这句话加到axWebBrowser1_NavigateComplete2事件代码中，如下：

public void axWebBrowser1_NavigateComplete2(object sender, AxSHDocVw.DWebBrowserEvents2_NavigateComplete2Event e)

axWebBrowser1.ExecWB(SHDocVw.OLECMDID.OLECMDID_HIDETOOLBARS, SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_DONTPROMPTUSER); //显示工具栏
Object o = e.pDisp;
Object oDocument = o.GetType().InvokeMember("Document", BindingFlags.GetProperty, null, o, null);
Object oApplication = o.GetType().InvokeMember("Application", BindingFlags.GetProperty, null, oDocument, null);
Object oName = o.GetType().InvokeMember("Name", BindingFlags.GetProperty, null, oApplication, null);
Microsoft.Office.Interop.Excel.Application eApp = (Microsoft.Office.Interop.Excel.Application)oApplication;
MessageBox.Show("File opened by: " + oName.ToString());
参考技术B 去微软网站下载个补丁，是专门解决这个问题的。
MicrosoftFixit50298.msi 参考技术C 楼主有没有解决这个问题？我运行的结果也是两个窗体，Excel只是单独被打开了，并没有嵌入窗体中

WinForm中如何实现嵌入form窗体(panel与子窗体)

参考技术A 今天在做项目时候遇到一个问题，窗体分为左右两部分，要求在左边栏点击按钮时，右边动态加载窗体最后想到用panel实现，经历几次失败，并查找资料后，终于搞定说明：如果多次切换需加入 panel.clear();清空原有panel内容环境：C# VS2008方法一：通过给panel加载子元素实现Form2 form =new Form2();form.FormBorderStyle = FormBorderStyle.None; //隐藏子窗体边框（去除最小花，最大化，关闭等按钮）form.TopLevel =false; //指示子窗体非顶级窗体this.panel1.Controls.Add(form);//将子窗体载入panelform.Show();方法二：指定父容器实现Form2 form=new Form2();form.MdiParent=this;//指定当前窗体为顶级Mdi窗体form.Parent=this.Panel1;//指定子窗体的父容器为Frm.FormBorderStyle = FormBorderStyle.None;//隐藏子窗体边框，当然也可以在子窗体的窗体加载事件中实现本回答被提问者采纳
