再谈CreateObject函数，VBS到底能调用哪些对象？

VBS的CreateObject函数到底能够创建哪些对象，几乎是每个VBS新手都困惑的问题，他们总是热衷于寻找“VBS对象大全”。

对象的注册信息 HKEY_CLASSES_ROOT\CLSID\{GUID} 下可能会有这样的一些子键：Control 说明该组件是一个 ActiveX 控件、Programmable 说明该组件支持自动化、Insertable 说明该组件可以被嵌入到一个 OLE 文档容器中。能找到 Programmable，说明支持自动化，也就是支持 IDispatch 接口，所以它可以被脚本语言使用。不过这种方式比较老了，现在已经被一个的组件类属代替，即 Implemented Categories 子键下面的 GUID 形式的子键。比如 HKEY_CLASSES_ROOT\CLSID\{72C24DD5-D70A-438B-8A42-98424B88AFB8}\Implemented Categories\{40FC6ED5-2438-11CF-A3DB-080036F12502}，看一下 HKEY_CLASSES_ROOT\Component Categories\{40FC6ED5-2438-11CF-A3DB-080036F12502} 下的 409 字符串值为 Automation Objects，也就是“自动化对象”。

也就是说，如果注册表中一个对象的ProgID对应的CLSID下包含有子键Programmable或者Implemented Categories\{40FC6ED5-2438-11CF-A3DB-080036F12502}，那么这个对象就能用CreateObject函数创建。

假设上面的说法正确，那么我们可以用下面的脚本获取“VBS对象大全”：

Option Explicit

Const HKEY_CLASSES_ROOT=&H80000000
Dim arrProgID, strProgID, strCLSID
Dim objReg, objFso, objFile, objShell

Set objReg=GetObject(“winmgmts:\\.\root\default:StdRegProv”)
Set objFso=CreateObject(“Scripting.FileSystemObject”)
Set objShell=CreateObject(“WScript.Shell”)

Set objFile=objFso.OpenTextFile(“ProgID.txt”, 2, True)

objReg.EnumKey HKEY_CLASSES_ROOT, “”, arrProgID
For Each strProgID In arrProgID
If GetCLSID(strProgID, strCLSID) Then
If IsProgrammable(strCLSID) Or IsAutomationObject(strCLSID) Then
objFile.WriteLine strProgID
End If
End If
Next
objShell.Run “ProgID.txt”

Function RegKeyExists(hKey, strSubKey)
Dim a, n
n=objReg.EnumKey(hKey, strSubKey, a)
If n=0 Then
RegKeyExists=True
Else
RegKeyExists=False
End If
End Function

Function IsAutomationObject(strCLSID)
Dim strSubKey
IsAutomationObject=False
strSubKey=”CLSID” & strCLSID & “\Implemented Categories”
If RegKeyExists(HKEY_CLASSES_ROOT, strSubKey) Then
strSubKey=strSubKey & “{40FC6ED5-2438-11CF-A3DB-080036F12502}”
If RegKeyExists(HKEY_CLASSES_ROOT, strSubKey) Then
IsAutomationObject=True
End If
End If
End Function

Function IsProgrammable(strCLSID)
IsProgrammable=RegKeyExists(HKEY_CLASSES_ROOT, _
“CLSID” & strCLSID & “\Programmable”)
End Function

Function GetCLSID(strProgID, strCLSID)
Dim s
GetCLSID=False
If RegKeyExists(HKEY_CLASSES_ROOT, strProgID & “\CLSID”) Then
objReg.GetStringValue HKEY_CLASSES_ROOT, strProgID & “\CLSID”, “”, s
If Not IsNull(s) Then
strCLSID=s
GetCLSID=True
End If
End If
End Function

上面的脚本显示在我的系统中存在1000多个对象可以调用。哇！VBS居然可以调用那么多对象！别高兴得太早，我前面说了“假设上面的说法正确”。实际上，UMU的说法并不完全正确，Programmable或者Implemented Categories为{40FC6ED5-2438-11CF-A3DB-080036F12502}的对象也不一定能够用CreateObject创建，比如我系统中有一个ComCtl3.Band就属于这种情况；另外，某些对象并没有Programmable或者Implemented Categories，但是照样可以用CreateObject创建，比如说WindowsInstaller.Installer。

所以不能单纯依靠注册表的是非存在Programmable或者Implemented Categories来判断，那么如果来判断呢？一种方法是根据《VBS技术内幕：CreateObject函数》里面说的，写一个C++程序来模拟CreateObject函数，判断对象是否支持IDispatch接口。不过这样太麻烦了，比较简单的方法是让CreateObject函数自己来判断：

Option Explicit

Const HKEY_CLASSES_ROOT=&H80000000
Dim arrProgID, strProgID, strCLSID
Dim objReg, objFso, objFile, objShell, O

Set objReg=GetObject(“winmgmts:\\.\root\default:StdRegProv”)
Set objFso=CreateObject(“Scripting.FileSystemObject”)
Set objShell=CreateObject(“WScript.Shell”)

Set objFile=objFso.OpenTextFile(“ProgID.txt”, 2, True)

objReg.EnumKey HKEY_CLASSES_ROOT, “”, arrProgID
For Each strProgID In arrProgID
If GetCLSID(strProgID, strCLSID) Then
If IsCreatable(strProgID) Then
objFile.WriteLine strProgID
End If
End If
Next
objShell.Run “ProgID.txt”

Function IsCreatable(strProgID)
On Error Resume Next
Dim O
Set O=CreateObject(strProgID)
If Err.Number=0 Then
IsCreatable=True
Else
IsCreatable=False
End If
Set O=Nothing
Err.Clear
End Function

Function RegKeyExists(hKey, strSubKey)
Dim a, n
n=objReg.EnumKey(hKey, strSubKey, a)
If n=0 Then
RegKeyExists=True
Else
RegKeyExists=False
End If
End Function
