我在 Windows 32 位中使用了 vba 代码。现在我已迁移到 Windows 10 64 位，我收到消息“应更新此项目中的代码以在 64 位系统上使用。请查看并更新 Declare 语句，然后用 PtrSafe 属性标记它们。” 我拥有的声明命令如下：

Public Declare Function GetUserNameEx Lib "Secur32.dll" Alias "GetUserNameExA" ( _
  ByVal NameFormat As EXTENDED_NAME_FORMAT, _
  ByVal lpNameBuffer As String, _
  ByRef lpnSize As Long) As Long

Public Enum EXTENDED_NAME_FORMAT
  NameUnknown = 0
  NameFullyQualifiedDN = 1
  NameSamCompatible = 2
  NameDisplay = 3
  NameUniqueId = 6
  NameCanonical = 7
  NameUserPrincipal = 8
  NameCanonicalEx = 9
  NameServicePrincipal = 10
  NameDnsDomain = 12
End Enum

Private Declare Function GetOpenFileName Lib "comdlg32.dll" Alias _
"GetOpenFileNameA" (pOpenfilename As OPENFILENAME) As Long

Private Type OPENFILENAME
    lStructSize As Long
    hwndOwner As Long
    hInstance As Long
    lpstrFilter As String
    lpstrCustomFilter As String
    nMaxCustFilter As Long
    nFilterIndex As Long
    lpstrFile As String
    nMaxFile As Long
    lpstrFileTitle As String
    nMaxFileTitle As Long
    lpstrInitialDir As String
    lpstrTitle As String
    flags As Long
    nFileOffset As Integer
    nFileExtension As Integer
    lpstrDefExt As String
    lCustData As Long
    lpfnHook As Long
    lpTemplateName As String
End Type

Public Declare Function ShellExecute _
    Lib "shell32.dll" _
    Alias "ShellExecuteA" ( _
    ByVal hwnd As Long, _
    ByVal lpOperation As String, _
    ByVal lpFile As String, _
    ByVal lpParameters As String, _
    ByVal lpDirectory As String, _
    ByVal nShowCmd As Long) _
    As Long

我查看了一些文档，但在使用 LongLong 和 LongPtr 语句时我无法真正理解。或者，如果它只是在 Declare 语句中声明 PtrSafe。

有人能帮我吗？

当它涉及内存地址时使用 LongPtr，当它只是一个数字时使用 Long。每当您在声明中使用 LongPtr 时，请包含 PtrSafe。所以你的 ShellExecute 声明将被（测试）：

#If VBA7 Then
Public Declare PtrSafe Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" ( _
        ByVal hWnd As LongPtr, ByVal lpOperation As String, ByVal lpFile As String, _
        ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As LongPtr
#Else
Public Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _
  (ByVal hWnd As Long, ByVal lpOperation As String, _
  ByVal lpFile As String, ByVal lpParameters As String, _
  ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
#End If

尝试用这些替换它们（未经测试）

GetUserNameEx 64 位/64 位

Public Enum EXTENDED_NAME_FORMAT
  NameUnknown = 0
  NameFullyQualifiedDN = 1
  NameSamCompatible = 2
  NameDisplay = 3
  NameUniqueId = 6
  NameCanonical = 7
  NameUserPrincipal = 8
  NameCanonicalEx = 9
  NameServicePrincipal = 10
  NameDnsDomain = 12
End Enum

#If VBA7 Then
    Public Declare PtrSafe Function GetUserNameEx Lib "Secur32.dll" Alias "GetUserNameExA" (ByVal NameFormat As EXTENDED_NAME_FORMAT, ByVal lpNameBuffer As String, ByRef lpnSize As Long) As Long
#Else
    Public Declare Function GetUserNameEx Lib "Secur32.dll" Alias "GetUserNameExA" (ByVal NameFormat As EXTENDED_NAME_FORMAT, ByVal lpNameBuffer As String, ByRef lpnSize As Long) As Long
#End If

GetOpenFileName 64 位/64 位

Type OPENFILENAME
        lStructSize As Long
        hwndOwner As LongPtr
        hInstance As LongPtr
        lpstrFilter As String
        lpstrCustomFilter As String
        nMaxCustFilter As Long
        nFilterIndex As Long
        lpstrFile As String
        nMaxFile As Long
        lpstrFileTitle As String
        nMaxFileTitle As Long
        lpstrInitialDir As String
        lpstrTitle As String
        flags As Long
        nFileOffset As Integer
        nFileExtension As Integer
        lpstrDefExt As String
        lCustData As LongPtr
        lpfnHook As LongPtr
        lpTemplateName As String
'#if (_WIN32_WINNT >= 0x0500)
        pvReserved As LongPtr
        dwReserved As Long
        FlagsEx As Long
'#endif // (_WIN32_WINNT >= 0x0500)
End Type

#If VBA7 Then
    Private Declare PtrSafe Function GetOpenFileName Lib "comdlg32.dll" Alias "GetOpenFileNameA" (pOpenfilename As OPENFILENAME) As Long
#Else
    Private Declare Function GetOpenFileName Lib "comdlg32.dll" Alias "GetOpenFileNameA" (pOpenfilename As OPENFILENAME) As Long
#End If

ShellExecute 64 位/64 位

#If VBA7 Then
    Private Declare PtrSafe Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As LongPtr, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As LongPtr
#Else
    Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
#End If
