.Net学习笔记

动态创建空间
 
 Dim pTool As ToolStrip = New ToolStrip()
        pTool.SendToBack()
        Controls.Add(pTool)
 或
 Dim pBtn As ToolStripButton = New ToolStripButton
        pBtn.TextAlign = ContentAlignment.MiddleRight
        pBtn.ImageAlign = ContentAlignment.MiddleLeft
 pBtn.Text = pCmd.Caption
        If pCmd.Bitmap <> 0 Then
  pBtn.Image = System.Drawing.Image.FromHbitmap(pCmd.Bitmap)
        End If
        BtnStrip.Items.Add(pBtn)
        AddHandler pBtn.Click, AddressOf Me.CommandClick
 或
 Type.GetType("System.Windows.Forms.CheckBox, System.Windows.Forms, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089")

动态使用字符串创建变量
 Dim pCmd As ICommand
 Dim ctlType As Type = Type.GetType(pCls)
 If Not ctlType Is Nothing Then
  pCmd = CType(System.Activator.CreateInstance(ctlType), ICommand)
 end if

注册表操作
 Microsoft.Win32
 Registry.ClassesRoot 对应于HKEY_CLASSES_ROOT子目录树
 Registry.CurrentUser 对应于HKEY_CURRENT_USER子目录树
 Registry.LocalMachine 对应于 HKEY_LOCAL_MACHINE子目录树
 Registry.User 对应于 HKEY_USER子目录树
 Registry.CurrentConfig 对应于HEKY_CURRENT_CONFIG子目录树
 Registry.DynDa 对应于HKEY_DYN_DATA子目录树
 Registry.PerformanceData 对应于HKEY_PERFORMANCE_DATA子目录树

 Dim hklm As RegistryKey = Registry.LocalMachine
 Dim software11 As RegistryKey = hklm.OpenSubKey ( "SYSTEM" ) '打开"SYSTEM"子健
 Dim software As RegistryKey = software11.OpenSubKey ( "A000" )  '打开"A000"子健
 
 Dim software11 As RegistryKey = hklm.OpenSubKey ( "SYSTEM" ,true ) '打开"SYSTEM"子健
 Dim software As RegistryKey = software11.OpenSubKey ( "A000" , true ) '打开"A000"子健
 Dim ddd As RegistryKey = software.CreateSubKey ( "ddd" )
 ddd.SetValue ( "www" , "1234" )

 Dim KeyCount As integer = software.SubKeyCount  '获得当前健下面有多少子健
 Dim Str ( ) As String = software.GetSubKeyNames ( )  '获得当前健下面所有子健组成的字符串数组

 Dim Str2 ( ) As String = sitekey.GetValueNames ( )  '获得当前子健下面所有健组成的字符串数组
 Dim ValueCount As integer = sitekey.ValueCount  '获得当前子健存在多少健值

快速结束当前应用程序
 Private Declare Sub ExitProcess Lib "kernel32" (ByVal uExitCode As Long)
 Private Declare Function GetExitCodeProcess Lib "kernel32" (ByVal hProcess As Long, lpExitCode As Long) As Long
 Private Declare Function GetCurrentProcess Lib "kernel32" () As Long
 ExitProcess GetExitCodeProcess(GetCurrentProcess, 0)

ShellExe

Dim LngHandle As Long
LngHandle = FindWindow(vbNullString, "供电范围颜色.")
If LngHandle > 0 Then
    BringWindowToTop (LngHandle)
    ShowWindow LngHandle, 5
    Exit Sub
End If

Shell "SysColors.exe", vbNormalFocus
