oracle client怎么用
然后在系统环境变量中配置Path,添加instantclient的路径,即C:\Oracle\instantclient_11_2; 增加环境变量: NLS_LANG=AMERICAN_AMERICA.ZHS16GBK TNS_ADMIN=C:\Oracle\instantclient_11_2 最后,在“TNS_ADMIN”的路径下增加一个tnsnames.ora文件,这个文件可以直接从已安装的Oracle的目录中拷贝,或者使用如下示例: # TNSNAMES.ORA Network Configuration File: C:\oracle\ora90\network\admin\tnsnames.ora # Generated by Oracle configuration tools. #sample ORCL_100 = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.168.100)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = orcl) ) ) 配置完成后,启动PLSQLDev,登录数据库成功。

c#怎样用代码实现最小化窗口
1.设置WinForm窗体属性showinTask=false
2.加notifyicon控件notifyIcon1,为控件notifyIcon1的属性Icon添加一个icon图标。
3.添加窗体最小化事件(首先需要添加事件引用):
this.SizeChanged += new System.EventHandler(this.Form1_SizeChanged);
//上面一行是主窗体InitializeComponent()方法中需要添加的引用
private void Form1_SizeChanged(object sender, EventArgs e)
{
if(this.WindowState == FormWindowState.Minimized)
{
this.Hide();
this.notifyIcon1.Visible=true;
}
}
4.添加点击图标事件(首先需要添加事件引用):
private void notifyIcon1_Click(object sender, EventArgs e)
{
this.Visible = true;
this.WindowState = FormWindowState.Normal;
this.notifyIcon1.Visible = false;
}
5.可以给notifyIcon添加右键菜单:
主窗体中拖入一个ContextMenu控件NicontextMenu,点中控件,在上下文菜单中添加菜单,notifyIcon1的ContextMenu行为中选中NicontextMenu 作为上下文菜单。
this.notifyIcon1 = new System.Windows.Forms.NotifyIcon(this.components);
this.NicontextMenu = new System.Windows.Forms.ContextMenu();
this.menuItem_Hide = new System.Windows.Forms.MenuItem();
this.menuItem_Show = new System.Windows.Forms.MenuItem();
this.menuItem_Aubot = new System.Windows.Forms.MenuItem();
this.menuItem_Exit = new System.Windows.Forms.MenuItem();
this.notifyIcon1.ContextMenu = this.NicontextMenu;
this.notifyIcon1.Icon = ((System.Drawing.Icon)(resources.GetObject( “NotifyIcon.Icon “)));
this.notifyIcon1.Text = “ “;
this.notifyIcon1.Visible = true;
this.notifyIcon1.DoubleClick += new System.EventHandler(this.notifyIcon1_DoubleClick);
this.notifyIcon1.Click += new System.EventHandler(this.notifyIcon1_Click);
this.NicontextMenu.MenuItems.AddRange(
new System.Windows.Forms.MenuItem
{
this.menuItem_Hide,
this.menuItem_Show,
this.menuItem_Aubot,
this.menuItem_Exit
}
);
//
// menuItem_Hide
//
this.menuItem_Hide.Index = 0;
this.menuItem_Hide.Text = “隐藏 “;
this.menuItem_Hide.Click += new System.EventHandler(this.menuItem_Hide_Click);
//
// menuItem_Show
//
this.menuItem_Show.Index = 1;
this.menuItem_Show.Text = “显示 “;
this.menuItem_Show.Click += new System.EventHandler(this.menuItem_Show_Click);
//
// menuItem_Aubot
//
this.menuItem_Aubot.Index = 2;
this.menuItem_Aubot.Text = “关于 “;
this.menuItem_Aubot.Click += new System.EventHandler(this.menuItem_Aubot_Click);
//
// menuItem_Exit
//
this.menuItem_Exit.Index = 3;
this.menuItem_Exit.Text = “退出 “;
this.menuItem_Exit.Click += new System.EventHandler(this.menuItem_Exit_Click);
