5.系统实现

5.1 首页登录模块设计实现

具体代码设计如下

private void Form2_Load(object sender, EventArgs e) {

//展开所有层次子节点

treeView1.Nodes[0].ExpandAll(); treeView3.Nodes[0].ExpandAll(); treeView4.Nodes[0].ExpandAll(); if (Form1.limits == 2) {

tabControl1.TabPages.Remove(tabPage3); tabControl1.TabPages.Remove(tabPage2); }

if (Form1.limits == 1) {

tabControl1.TabPages.Remove(tabPage4); }

comboBox1.SelectedIndex = 0; comboBox3.SelectedIndex = 0; comboBox4.SelectedIndex = 0; }

//窗体关闭

private void button8_Click(object sender, EventArgs e) {

Application.Exit(); }

//窗体隐藏

private void button9_Click(object sender, EventArgs e) {

this.Hide(); }

//双击窗体

private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)

{

this.Show();//显示窗体

this.WindowState = FormWindowState.Normal;//窗体正常显示 }

//移动窗体的位置

//1.鼠标按下的那一刻，记录下鼠标在窗体上的位置 int x = 0;
