Because of its length, only the code for the function itself is shown on this page.
The demo script that shows how to use this function is available as a separate download.
复制代码 代码如下:
Function ReadRegValue( myComputer, myRegPath, myRegValue )
' This function reads a value from the registry of any WMI
' enabled computer.
'
' Arguments:
' myComputer a computer name or IP address,
' or a dot for the local computer
' myRegPath a full registry key path, e.g.
' HKEY_CLASSES_ROOT\.jpg or
' HKLM\SOFTWARE\Microsoft\DirectX
' myRegValue the value name to be queried, e.g.
' InstalledVersion or "" for default
' values
'
' The function returns an array with the following elements:
' ReadRegValue(0) the computer name (the first argument)
' ReadRegValue(1) the hive number (see const declarations)
' ReadRegValue(2) the key path without the hive
' ReadRegValue(3) the value name (the third argument)
' ReadRegValue(4) the error number: 0 means no error
' ReadRegValue(5) the data type of the result
' ReadRegValue(6) the actual data, or the first element of an
' array of data for REG_BINARY or REG_MULTI_SZ
