C语言操作ADO数据库 这些操作是对一个微软Access 2000数据库进行的,但是SQL或是其它 ADO数据源可以通过简单的改变连接字符串来使用.

1.引用UtilityLibrary
using System.Resources;
using System.Reflection;
using System.Xml;
using UtilityLibrary.Menus;
using System.Diagnostics;
2.编辑MainMenu.xml,定制相应的项目
<?xml version="1.0" encoding="UTF-8"?>
<MainMenu>
	<Menu Name="文件(&amp;F)" Shortcut="" Icon="" Checked="False" Radio="False" Enabled="True">
		<Menu Name="退出(&amp;x)" Shortcut="" Icon="" Checked="False" Radio="False" Enabled="True"/>
	</Menu>
	<Menu Name="任务(&amp;T)" Shortcut="" Icon="" Checked="False" Radio="False" Enabled="True">
		<Menu Name="我知道(&amp;I)" Shortcut="" Icon="" Checked="False" Radio="False" Enabled="True"/>
		<Menu Name="管理(&amp;M)..." Shortcut="" Icon="" Checked="False" Radio="False" Enabled="True"/>
	</Menu>
	<Menu Name="帮助(&amp;H)" Shortcut="" Icon="" Checked="False" Radio="False" Enabled="True">
		<Menu Name="目录(&amp;C)..." Shortcut="" Icon="" Checked="False" Radio="False" Enabled="True"/>
		<Menu Name="注册(&amp;R)..." Shortcut="" Icon="" Checked="False" Radio="False" Enabled="True"/>
		<Menu Name="关于(&amp;A)..." Shortcut="" Icon="" Checked="False" Radio="False" Enabled="True"/>
	</Menu>	
</MainMenu>
3.编写代码处理程序
a.申明并构造rm;
static ResourceManager rm;
rm = new ResourceManager("VSNetMenus", Assembly.GetCallingAssembly());
b.复制如下代码:
public  MenuItem[] CreateMainMenu()
		{
			string menuFile = Application.StartupPath + "\\" + "mainmenu.xml";//读配置文件
			XmlDocument doc = new XmlDocument();
			doc.Load(menuFile);
			
			XmlNodeList topMenus = doc.DocumentElement.ChildNodes;
			MenuItem[] menuItems = new MenuItem[topMenus.Count];
			int i = 0;
			foreach ( XmlElement element in topMenus )  
			{
				menuItems[i++] = ProcessMenuItem(element);
			}
            			
			return menuItems;
		}

		public static MenuItem ProcessMenuItem(XmlElement xmlelement)//生成菜单
		{
			string menuName = xmlelement.Attributes["Name"].InnerXml;
			if ( menuName.IndexOf("&") != -1 ) 
				menuName = menuName.Replace("&amp;", "&");
            string menuShortcutString = xmlelement.Attributes["Shortcut"].InnerXml;
			string menuIcon = xmlelement.Attributes["Icon"].InnerXml;
			string menuChecked = xmlelement.Attributes["Checked"].InnerXml;
			string menuRadio = xmlelement.Attributes["Radio"].InnerXml;
			string menuEnabled = xmlelement.Attributes["Enabled"].InnerXml;
			
			Shortcut menuShortcut = Shortcut.None;
			
			if ( menuShortcutString != "" ) 
			{
				menuShortcut = (Shortcut)((Shortcut.F1.GetType()).InvokeMember(menuShortcutString, 
					BindingFlags.GetField, null, Shortcut.F1, new object[0]));
			}
			//订阅事件
			MenuItemEx parentMenu = new MenuItemEx(menuName, new EventHandler(SelectMenuItem), menuShortcut);
			if ( menuIcon != "" )
				parentMenu.Icon = GetIcon(menuIcon);//加载图标
			if ( menuChecked == "True" )
				parentMenu.Checked = true;
			if ( menuEnabled == "False" ) 
				parentMenu.Enabled = false;
			if ( menuRadio == "True" )
				parentMenu.RadioCheck = true;
									
			XmlNodeList nodes = xmlelement.ChildNodes;
			if ( nodes.Count > 0 )
			{
				MenuItem[] menuItems = new MenuItem[nodes.Count];
				int i = 0 ;
				foreach ( XmlElement node in nodes ) 
				{
					menuItems[i] = ProcessMenuItem(node);
					if ( menuItems[i] != null)
						parentMenu.MenuItems.Add(menuItems[i]);
					i++;
				}
			}
			return parentMenu;
		}

		public  Bitmap GetIcon(string iconName)
		{
			Bitmap icon = (Bitmap)rm.GetObject(iconName);
			return icon;
		}
		
		public  void SelectMenuItem(object sender, EventArgs e)//事件处理程序
		{
			if (typeof(MenuItemEx).IsInstanceOfType(sender)) 
			{
				MenuItemEx item = (MenuItemEx)sender;
				string menuText = item.Text;				
//				MessageBox.Show(menuText);
				switch(menuText)
				{
					case "退出(&x)":
						MessageBox.Show("退出");
						break;
					case "我知道(&I)":
						MessageBox.Show("我知道");
						break;
					case "管理(&M)...":
						MessageBox.Show("管理");
						break;
					case "目录(&C)...":
						MessageBox.Show("目录");
						break;
					case "注册(&R)...":
						MessageBox.Show("注册");
						break;
					case "关于(&A)...":
						MessageBox.Show("关于");
						break;
					default:
						MessageBox.Show("未知");
						break;

				}
			}
		}
c.改变Main
public static void Main(string[] args)
		{
			Form1 mainForm = new Form1();
            mainForm.Menu = new MainMenu(mainForm.CreateMainMenu());
			mainForm.BackColor = Color.White;
			
			// make sure we respond to systemcolorchanges
            mainForm.SystemColorsChanged += new EventHandler(MenuItemEx.UpdateMenuColors);			

			Application.Run(mainForm);

		}
d.
public  void SelectMenuItem(object sender, EventArgs e)//事件处理程序
		{
			if (typeof(MenuItemEx).IsInstanceOfType(sender)) 
			{
				MenuItemEx item = (MenuItemEx)sender;
				string menuText = item.Text;				
//				MessageBox.Show(menuText);
				switch(menuText)
				{
					case "退出(&x)":
						MessageBox.Show("退出");
						break;
					case "我知道(&I)":
						MessageBox.Show("我知道");
						break;
					case "管理(&M)...":
						MessageBox.Show("管理");
						break;
					case "目录(&C)...":
						MessageBox.Show("目录");
						break;
					case "注册(&R)...":
						MessageBox.Show("注册");
						break;
					case "关于(&A)...":
						MessageBox.Show("关于");
						break;
					default:
						MessageBox.Show("未知");
						break;

				}
			}
		}
