我正在尝试使用提供给this的解决方案,但是,每当我尝试运行最基本的内容时,都会出现Object not Defined
错误。我以为这是我的错(未安装ScriptControl)。但是,我尝试按照here中的描述进行安装,但无济于事。
我正在运行带有Office 2010 64位的Windows 7 Professional x64。
最佳答案
您可以创建ActiveX对象(例如ScriptControl
),该对象可以通过64位VBA版本上的mshta x86主机在32位Office版本上使用,下面是示例(将代码放入标准VBA项目模块中):
Option Explicit
Sub Test()
Dim oSC As Object
Set oSC = CreateObjectx86("ScriptControl") ' create ActiveX via x86 mshta host
Debug.Print TypeName(oSC) ' ScriptControl
' do some stuff
CreateObjectx86 Empty ' close mshta host window at the end
End Sub
Function CreateObjectx86(sProgID)
Static oWnd As Object
Dim bRunning As Boolean
#If Win64 Then
bRunning = InStr(TypeName(oWnd), "HTMLWindow") > 0
If IsEmpty(sProgID) Then
If bRunning Then oWnd.Close
Exit Function
End If
If Not bRunning Then
Set oWnd = CreateWindow()
oWnd.execScript "Function CreateObjectx86(sProgID): Set CreateObjectx86 = CreateObject(sProgID): End Function", "VBScript"
End If
Set CreateObjectx86 = oWnd.CreateObjectx86(sProgID)
#Else
If Not IsEmpty(sProgID) Then Set CreateObjectx86 = CreateObject(sProgID)
#End If
End Function
Function CreateWindow()
' source http://forum.script-coding.com/viewtopic.php?pid=75356#p75356
Dim sSignature, oShellWnd, oProc
On Error Resume Next
sSignature = Left(CreateObject("Scriptlet.TypeLib").GUID, 38)
CreateObject("WScript.Shell").Run "%systemroot%\syswow64\mshta.exe about:""<head><script>moveTo(-32000,-32000);document.title='x86Host'</script><hta:application showintaskbar=no /><object id='shell' classid='clsid:8856F961-340A-11D0-A96B-00C04FD705A2'><param name=RegisterAsBrowser value=1></object><script>shell.putproperty('" & sSignature & "',document.parentWindow);</script></head>""", 0, False
Do
For Each oShellWnd In CreateObject("Shell.Application").Windows
Set CreateWindow = oShellWnd.GetProperty(sSignature)
If Err.Number = 0 Then Exit Function
Err.Clear
Next
Loop
End Function
它有几个缺点:在任务管理器中列出了单独运行的
mshta.exe
进程是必需的,并且显示了Alt + Tab隐藏的HTA窗口:另外,您还必须在代码末尾通过
CreateObjectx86 Empty
关闭该HTA窗口。更新
您可以使主机窗口自动关闭:通过创建类实例或mshta活动跟踪。
第一种方法假定您创建一个类实例作为包装,该实例使用
Private Sub Class_Terminate()
关闭窗口。注意:如果Excel在执行代码时崩溃,则没有类终止,因此该窗口将保留在后台。
将以下代码放入名为
cMSHTAx86Host
的类模块中: Option Explicit
Private oWnd As Object
Private Sub Class_Initialize()
#If Win64 Then
Set oWnd = CreateWindow()
oWnd.execScript "Function CreateObjectx86(sProgID): Set CreateObjectx86 = CreateObject(sProgID) End Function", "VBScript"
#End If
End Sub
Private Function CreateWindow()
' source http://forum.script-coding.com/viewtopic.php?pid=75356#p75356
Dim sSignature, oShellWnd, oProc
On Error Resume Next
sSignature = Left(CreateObject("Scriptlet.TypeLib").GUID, 38)
CreateObject("WScript.Shell").Run "%systemroot%\syswow64\mshta.exe about:""<head><script>moveTo(-32000,-32000);document.title='x86Host'</script><hta:application showintaskbar=no /><object id='shell' classid='clsid:8856F961-340A-11D0-A96B-00C04FD705A2'><param name=RegisterAsBrowser value=1></object><script>shell.putproperty('" & sSignature & "',document.parentWindow);</script></head>""", 0, False
Do
For Each oShellWnd In CreateObject("Shell.Application").Windows
Set CreateWindow = oShellWnd.GetProperty(sSignature)
If Err.Number = 0 Then Exit Function
Err.Clear
Next
Loop
End Function
Function CreateObjectx86(sProgID)
#If Win64 Then
If InStr(TypeName(oWnd), "HTMLWindow") = 0 Then Class_Initialize
Set CreateObjectx86 = oWnd.CreateObjectx86(sProgID)
#Else
Set CreateObjectx86 = CreateObject(sProgID)
#End If
End Function
Function Quit()
#If Win64 Then
If InStr(TypeName(oWnd), "HTMLWindow") > 0 Then oWnd.Close
#End If
End Function
Private Sub Class_Terminate()
Quit
End Sub
将以下代码放入标准模块中:
Option Explicit
Sub Test()
Dim oHost As New cMSHTAx86Host
Dim oSC As Object
Set oSC = oHost.CreateObjectx86("ScriptControl") ' create ActiveX via x86 mshta host
Debug.Print TypeName(oSC) ' ScriptControl
' do some stuff
' mshta window is running until oHost instance exists
' if necessary you can manually close mshta host window by oHost.Quit
End Sub
对于那些由于某种原因不想使用类的人的第二种方法。关键是mshta窗口每隔500毫秒检查一次VBA的
Static oWnd
变量的状态,该变量通过内部CreateObjectx86
函数调用不带参数的setInterval()
,如果引用丢失(如果用户在VBA Project窗口中按了Reset或工作簿已关闭(错误1004)。注意:VBA断点(错误57097),用户编辑的工作表单元格,打开的对话框模式窗口(如“打开/保存/选项”(错误-2147418111))将暂停跟踪,因为它们使应用程序无法响应来自mshta的外部调用。处理此类操作异常,完成后代码将继续工作,不会崩溃。
将以下代码放入标准模块中:
Option Explicit
Sub Test()
Dim oSC As Object
Set oSC = CreateObjectx86("ScriptControl") ' create ActiveX via x86 mshta host
Debug.Print TypeName(oSC) ' ScriptControl
' do some stuff
' mshta window is running until Static oWnd reference to window lost
' if necessary you can manually close mshta host window by CreateObjectx86 Empty
End Sub
Function CreateObjectx86(Optional sProgID)
Static oWnd As Object
Dim bRunning As Boolean
#If Win64 Then
bRunning = InStr(TypeName(oWnd), "HTMLWindow") > 0
Select Case True
Case IsMissing(sProgID)
If bRunning Then oWnd.Lost = False
Exit Function
Case IsEmpty(sProgID)
If bRunning Then oWnd.Close
Exit Function
Case Not bRunning
Set oWnd = CreateWindow()
oWnd.execScript "Function CreateObjectx86(sProgID): Set CreateObjectx86 = CreateObject(sProgID) End Function", "VBScript"
oWnd.execScript "var Lost, App;": Set oWnd.App = Application
oWnd.execScript "Sub Check(): On Error Resume Next: Lost = True: App.Run(""CreateObjectx86""): If Lost And (Err.Number = 1004 Or Err.Number = 0) Then close: End If End Sub", "VBScript"
oWnd.execScript "setInterval('Check();', 500);"
End Select
Set CreateObjectx86 = oWnd.CreateObjectx86(sProgID)
#Else
Set CreateObjectx86 = CreateObject(sProgID)
#End If
