經典VBS代碼

下面是我認為比較經典的VBS代碼,其中包括Windows 2000的管理、編碼、解碼等等...
希望大家能夠也喜歡上VBS。

登出/重起/關閉本地Windows NT/2000 電腦

Sub ShutDown()
Dim Connection, WQL, SystemClass, System

'Get connection To local wmi
Set Connection = GetObject("winmgmts:root\cimv2")

'Get Win32_OperatingSystem objects - only one object In the collection
WQL = "Select Name From Win32_OperatingSystem"
Set SystemClass = Connection.ExecQuery(WQL)

'Get one system object
'I think there is no way To get the object using URL?
For Each System In SystemClass
System.Win32ShutDown (2)
Next
End Sub

登出/重起/關閉遠程Windows NT/2000 電腦

Sub ShutDownEx(Server, User, Password) Dim Connection, WQL, SystemClass, System 'Get connection To remote wmi Dim Locator Set Locator = CreateObject("WbemScripting.SWbemLocator") Set Connection = Locator.ConnectServer(Server, "root\cimv2", User, Password) 'Get Win32_OperatingSystem objects - only one object In the collection WQL = "Select Name From Win32_OperatingSystem" Set SystemClass = Connection.ExecQuery(WQL) 'Get one system object 'I think there is no way To get the object using URL? For Each System In SystemClass System.Win32ShutDown (2) NextEnd Sub

上面兩段代碼都用到了WMI中Win32_OperationSystem的方法Win32ShutDown,Win32ShutDown(flag)中flag的參數可以是下表中的任意一種: 值 描述
0 登出
0 + 4 強制登出
1 關機
1 + 4 強制關機
2 重起
2 + 4 強制重起
8 關閉電源
8 + 4 強制關閉電源

使用ADODB.Stream對象寫二進位檔案

Function SaveBinaryData(FileName, ByteArray)
Const adTypeBinary = 1
Const adSaveCreateOverWrite = 2

'Create Stream object
Dim BinaryStream
Set BinaryStream = CreateObject("ADODB.Stream")

'Specify stream type - we want To save binary data.
BinaryStream.Type = adTypeBinary

'Open the stream And write binary data To the object
BinaryStream.Open
BinaryStream.Write ByteArray

'Save binary data To disk
BinaryStream.SaveToFile FileName, adSaveCreateOverWrite
End Function

使用ADODB.Stream對象寫文字檔

Function SaveTextData(FileName, Text, CharSet)
Const adTypeText = 2
Const adSaveCreateOverWrite = 2

'Create Stream object
Dim BinaryStream
Set BinaryStream = CreateObject("ADODB.Stream")

'Specify stream type - we want To save text/string data.
BinaryStream.Type = adTypeText

'Specify charset For the source text (unicode) data.
If Len(CharSet) > 0 Then
BinaryStream.CharSet = CharSet
End If

'Open the stream And write binary data To the object
BinaryStream.Open
BinaryStream.WriteText Text

'Save binary data To disk
BinaryStream.SaveToFile FileName, adSaveCreateOverWrite
End Function

使用ADODB.Stream對象讀二進位檔案

Function ReadBinaryFile(FileName)
Const adTypeBinary = 1

'Create Stream object
Dim BinaryStream
Set BinaryStream = CreateObject("ADODB.Stream")

'Specify stream type - we want To get binary data.
BinaryStream.Type = adTypeBinary

'Open the stream
BinaryStream.Open

'Load the file data from disk To stream object
BinaryStream.LoadFromFile FileName

'Open the stream And get binary data from the object
ReadBinaryFile = BinaryStream.Read
End Function

使用ADODB.Stream對象讀文字檔

Function ReadTextFile(FileName, CharSet)
Const adTypeText = 2

'Create Stream object
Dim BinaryStream
Set BinaryStream = CreateObject("ADODB.Stream")

'Specify stream type - we want To get binary data.
BinaryStream.Type = adTypeText

'Specify charset For the source text (unicode) data.
If Len(CharSet) > 0 Then
BinaryStream.CharSet = CharSet
End If

'Open the stream
BinaryStream.Open

'Load the file data from disk To stream object
BinaryStream.LoadFromFile FileName

'Open the stream And get binary data from the object
ReadTextFile = BinaryStream.ReadText
End Function

使用FileSystemObject對象寫檔案

Function SaveBinaryDataTextStream(FileName, ByteArray)
'Create FileSystemObject object
Dim FS: Set FS = CreateObject("Scripting.FileSystemObject")

'Create text stream object
Dim TextStream
Set TextStream = FS.CreateTextFile(FileName)

'Convert binary data To text And write them To the file
TextStream.Write BinaryToString(ByteArray)
End Function

讀取和寫入Windows的INI檔案

Sub WriteINIStringVirtual(Section, KeyName, value, FileName)
WriteINIString Section, KeyName, value, _
Server.MapPath(FileName)
End Sub
Function GetINIStringVirtual(Section, KeyName, Default, FileName)
GetINIStringVirtual = GetINIString(Section, KeyName, Default, _
Server.MapPath(FileName))
End Function
