MsgWaitForMultipleObjects返回Office 2013 64位版本的错误

我的公司有一个Office插件,可以在Office 2007和2010上正常运行。现在Microsoft有一个新的Office 2013,我们需要在Office 2013(32位和64位)中测试加载项。

大多数函数都运行正常,但不知何故有一个函数使用MsgWaitForMultipleObjects()在Office 2013 64位版本中无法正常工作,它在32位Office 2013上运行正常。下面是我的代码,它属于一个功能:

Dim lReturn As Integer

  Do While True

     'Wait on event
     lReturn = MsgWaitForMultipleObjects(1, handle, 0, timeout, QS_ALLEVENTS)

     Select Case lReturn

        Case -1

           'Call failed
           Err.Raise(vbObjectError, "WaitWithEvents", "MsgWaitForMultipleObjects Failed")

        Case STATUS_TIMEOUT

           'Timed out
           WaitWithEvents = STATUS_TIMEOUT
           Exit Function

        Case 1

           'Event needs to be processed
           Application.DoEvents()

        Case Else

           'Event has been signaled
           WaitWithEvents = 0
           Exit Function

     End Select
  Loop

大多数情况下,MsgWaitForMultipleObjects()将返回-1,Office应用程序将崩溃/挂起。我是MsgWaitForMultipleObjects()的新手,并试图在这里和那里更改代码,但仍然无法解决问题。

MsgWaitForMultipleObjects()在64位版本的Office 2013中运行良好吗?或者需要针对64位Office进行一些修改?或者我需要以不同方式注册DLL?加载项项目设置为任何cpu。

感谢。

我找到了解决方案,问题出在MsgWaitForMultipleObjects()的声明中。 以前我这样说过:

Private Declare Function MsgWaitForMultipleObjects Lib "user32" (ByVal nCount As Integer, ByRef pHandles As Integer, ByVal fWaitAll As Integer, ByVal dwMilliseconds As Integer, ByVal dwWakeMask As Integer) As Integer

解决方案是:

Private Declare Function MsgWaitForMultipleObjects Lib "user32" (ByVal nCount As Integer, ByRef pHandles As IntPtr, ByVal fWaitAll As Boolean, ByVal dwMilliseconds As UInteger, ByVal dwWakeMask As Integer) As Integer
