c# 禁用Excel窗口關閉按鈕

 先是聲明API的類：

using System; using System.Runtime.InteropServices; class Win32 { /// <summary> /// 查找窗口句柄 /// </summary> /// <param name="lpClassName">窗口類名</param> /// <param name="lpWindowName">窗口標題</param> /// <returns></returns> [DllImport("user32")] public static extern int FindWindow(string lpClassName, string lpWindowName); [DllImport("user32")] public static extern int GetSystemMenu(int hwnd, int bRevert); [DllImport("user32")] public static extern int RemoveMenu(int hMenu, int nPosition, int wFlags); }

 

然後是窗體部分，比較簡單：

private void button1_Click(object sender, EventArgs e) { if (button1.Text == "禁用關閉") { DisableClose(); MessageBox.Show("Excel關閉已禁用"); button1.Text = "已禁用"; } } public const int MF_BYPOSITION = 0x400; protected void DisableClose() { int excel = Win32.FindWindow("XLMAIN", null);//Excel2003窗體類 int close = Win32.GetSystemMenu(excel,0); Win32.RemoveMenu(close, 6, MF_BYPOSITION); }

 

暫時只支持Excel2003，
