Winform窗体的一些设置

设置winform窗体上默认的按钮为Enter或Esc键，只需设置窗体的acceptbutton和cancelbutton两个属性。如果是asp.net页面只需设置form表单的defaultbutton属性。

 

在C# windows Form程序中添加托盘可以使用NotifyIcon控件，使程序不显示在工具栏上可以设置ShowInTaskbar 属性。

 

点击关闭按钮最小化窗体：

 

protected override void WndProc(ref   Message m)   
{   
    const int WM_SYSCOMMAND = 0x0112;   
    const int SC_CLOSE = 0xF060;   
    if (m.Msg == WM_SYSCOMMAND && (int)m.WParam == SC_CLOSE)   
    {//捕捉关闭窗体消息      
        //   User   clicked   close   button      
        this.WindowState = FormWindowState.Minimized;   
        return;   
    }   
    base.WndProc(ref   m);   
} 
 

定义快捷键退出：

 

        protected override bool ProcessCmdKey(ref System.Windows.Forms.Message msg, System.Windows.Forms.Keys keyData)
        {
            int WM_KEYDOWN = 256;
            int WM_SYSKEYDOWN = 260;   
            //if (keyData==Keys.F4)
            //{
            //    this.Close();
            //}
            if (msg.Msg == WM_KEYDOWN | msg.Msg == WM_SYSKEYDOWN)
            {
                switch (keyData)
                {
                    case Keys.Escape:
                        this.Close();//Esc退出                    
                        break;
                }
            }
            return false;
        }

 

 

开机自动运行：

       

private void AutoRun()
        {
            RegistryKey R_local = Registry.LocalMachine;
            RegistryKey R_run = R_local.CreateSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Run");
            //键值不存在
            if (R_run.GetValue("123") == null)
            {
                string R_startPath = Application.ExecutablePath;
                R_run.SetValue("123", R_startPath);
            }
            //存在
            else
            {
                try
                {
                    R_run.DeleteValue("123", false);
                }
                catch (Exception ex)
                {
                    MessageBox.Show(ex.Message, "提示", MessageBoxButtons.OK, MessageBoxIcon.Error);
                }
            }
            R_run.Close();
            R_local.Close();
        }

 

 

//取得设备硬盘的卷标号
public string GetDiskVolumeSerialNumber()
{
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid=\"d:\"");

return disk.GetPropertyValue("VolumeSerialNumber").ToString();
}
//获得CPU的序列号
public string getCpu()
{
string strCpu = null;
ManagementClass myCpu = new ManagementClass("win32_Processor");
ManagementObjectCollection myCpuConnection = myCpu.GetInstances();
foreach (ManagementObject myObject in myCpuConnection)
{
