在Win64 VBA办公室中声明声明

Question

我在Windows 32位使用了VBA代码。现在，我已经迁移到Windows 10 64位，我收到了"该项目中的代码应更新以在64位系统上使用。请查看和更新声明语句，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

我已经查看了一些文档，但是在使用Longlong和Longptr语句时，我真的无法理解。或者仅在声明语句中仅声明ptrsafe。

链接到Microsoft文档https://msdn.microsoft.com/en-us/library/office/ee691831（v = Office.14）.aspx

有人可以帮我吗？

Answer 1

当涉及内存地址时，您会使用longptr，而仅在数字时长时间。每当您在声明中使用longptr时，都会加入PTRSAFE。因此，您的Shellexecute声明将进行（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（未经测试）

代替它们

  NameCanonical = 7

  NameCanonicalEx = 9
  NameServicePrincipal = 10
