Excel VBA中的ShellExecuteEx崩溃

自Windows更新发生后，对ShellExecuteEx（sExecuteInfo）的API调用崩溃，说明：

0x75F7A529（shell32.dll）访问冲突处未处理的异常 读取位置0x686903

我不知道这里怎么了，你能帮我吗

定义：

Private Type SHELLEXECUTEINFO
cbSize       As Long
fMask        As Long
Hwnd         As Long
lpVerb       As String
lpFile       As String
lpParameters As String
lpDirectory  As String
nShow        As Long
hInstApp     As Long
lpIDList     As Long
lpClass      As String
hkeyClass    As Long
dwHotKey     As Long
hIcon        As Long
hProcess     As Long
End Type

Private Const STILL_ACTIVE As Long = &H103 ' Constant for the lpExitCode parameter of the GetExitCodeProcess API function.

Private Declare PtrSafe Function ShellExecuteEx Lib "shell32.dll" Alias "ShellExecuteExA" (lpExecInfo As SHELLEXECUTEINFO) As Long

代码：

使用微软推荐的方法。 通过不同的API调用推荐方法，我可以确认它工作可靠。我在这里发布代码模块（采用本文中的代码）

以下VBA模块使用API调用

CreateProcessA（）

，等待应用程序完成并返回ERRORLEVEL代码作为结果：

Option Explicit

Private Type STARTUPINFO
  cb As Long
  lpReserved As String
  lpDesktop As String
  lpTitle As String
  dwX As Long
  dwY As Long
  dwXSize As Long
  dwYSize As Long
  dwXCountChars As Long
  dwYCountChars As Long
  dwFillAttribute As Long
  dwFlags As Long
  wShowWindow As Integer
  cbReserved2 As Integer
  lpReserved2 As Long
  hStdInput As Long
  hStdOutput As Long
  hStdError As Long
End Type

Private Type PROCESS_INFORMATION
  hProcess As Long
  hThread As Long
  dwProcessID As Long
  dwThreadID As Long
End Type

Private Declare Function WaitForSingleObject Lib "kernel32" (ByVal _
  hHandle As Long, ByVal dwMilliseconds As Long) As Long

Private Declare Function CreateProcessA Lib "kernel32" (ByVal _
  lpApplicationName As String, ByVal lpCommandLine As String, ByVal _
  lpProcessAttributes As Long, ByVal lpThreadAttributes As Long, _
  ByVal bInheritHandles As Long, ByVal dwCreationFlags As Long, _
  ByVal lpEnvironment As Long, ByVal lpCurrentDirectory As String, _
  lpStartupInfo As STARTUPINFO, lpProcessInformation As _
  PROCESS_INFORMATION) As Long

Private Declare Function CloseHandle Lib "kernel32" _
  (ByVal hObject As Long) As Long

Private Declare Function GetExitCodeProcess Lib "kernel32" _
  (ByVal hProcess As Long, lpExitCode As Long) As Long

Private Const NORMAL_PRIORITY_CLASS = &H20&
Private Const INFINITE = -1&

Public Function ExecCmd(CommandLine As String) As Long
  Dim proc As PROCESS_INFORMATION
  Dim Start As STARTUPINFO
  Dim ret As Long

  ' Initialize the STARTUPINFO structure:
  Start.cb = Len(Start)

  ' Start the shelled application:
  ret& = CreateProcessA(vbNullString, CommandLine, 0&, 0&, 1&, _
     NORMAL_PRIORITY_CLASS, 0&, vbNullString, Start, proc)

  ' Wait for the shelled application to finish:
     ret& = WaitForSingleObject(proc.hProcess, INFINITE)
     Call GetExitCodeProcess(proc.hProcess, ret&)
     Call CloseHandle(proc.hThread)
     Call CloseHandle(proc.hProcess)
     ExecCmd = ret&
End Function

如果将所有代码存储为例如

ShellExecModule

，则可以将其称为

Dim errorLevelValue As Long
errorLevelValue = ShellExecModule.ExecCmd(CommandLine)

---

Len（sExecuteInfo）返回什么？sExecuteInfo.cbSize=60 Office 32位或64位的可能副本？另外，请您留下一句话，为什么您决定使用

ShellExecuteEx

而不是

ShellExecuteEx

？@miroxlav：特别是

ShellExecuteExA

——VBA不是Unicode吗？谢谢您提供的信息，我确实应用了它，它工作得很顺利。

Dim errorLevelValue As Long
errorLevelValue = ShellExecModule.ExecCmd(CommandLine)
