64位Office代码不起作用 [英] Code does not work on 64 bit Office

问题描述

我应该在64位系统上找出excel VBA代码兼容性问题。我不使用VB语言和下面的代码不是我的，但我必须解决这个问题。

Excel VB代码：

  Option Explicit 
 
私有声明函数WideCharToMultiByte Libkernel32.dll（ByVal CodePage As Long，ByVal dwFlags As Long，ByVal lpWideCharStr As Long，ByVal cchWideChar As Long，ByRef lpMultiByteStr As Byte，ByVal cchMultiByte As Long，ByVal lpDefaultChar As String，ByRef lpUsedDefaultChar As Long）As Long 
 
 Private Const CP_UTF8 As Long = 65001 
 Private Const ERROR_INSUFFICIENT_BUFFER As Long = 122& 
 
 
公共函数ToUTF8（s as String）As Byte（）
 
如果Len（s）= 0，则退出函数
 
 
 Dim ccb As Long 
 ccb = WideCharToMultiByte（CP_UTF8，0，StrPtr（s），Len（s），ByVal 0& 0，vbNullString，ByVal 0&）
 
如果ccb = 0然后
 Err.Raise 5，内部错误。 
 End If 
 
 Dim b（）As Byte 
 ReDim b（1 to ccb）
 
如果WideCharToMultiByte（CP_UTF8，0，StrPtr（s） ，Len（s），b（LBound（b）），ccb，vbNullString，ByVal 0&）= 0然后
 Err.Raise 5，内部错误。 
 Else 
 ToUTF8 = b 
如果
 
结束函数
  

我试图添加条件＃如果VBA7 和 PtrSave 到任何地方，但工作表仍然不工作。

这是我在Office 64位中尝试的代码

  Option Explicit 
 
＃如果VBA7然后
私有声明PtrSafe函数WideCharToMultiByte Libkernel32（ByVal CodePage As Integer，ByVal dwFlags As Long，ByVal lpWideCharStr As LongPtr，ByVal cchWideChar As Long ，ByVal lpMultiByteStr As Long，ByVal cchMultiByte As LongPtr，ByVal lpDefaultChar As Long，ByVal lpUsedDefaultChar As Long）As LongPtr 
 #Else 
私有声明函数WideCharToMultiByte Libkernel32.dll（ByVal CodePage As Long，ByVal dwFlags As Long，ByVal lpWideCharStr As Long，ByVal cchWideChar As Long，ByRef lpMultiByteStr As Byte，ByVal cchMultiByte As Long，ByVal lpDefaultChar As String，ByRef lpUsedDefaultChar As Lon g）As Long 
 #EndIf 
 
 Private Const CP_UTF8 As Long = 65001 
 Private Const ERROR_INSUFFICIENT_BUFFER As Long = 122& 
 
 
公共函数ToUTF8（s as String）As Byte（）
 
如果Len（s）= 0，则退出函数
 
 
 Dim ccb As LongPtr 
 ccb = WideCharToMultiByte（CP_UTF8，0，StrPtr（s），Len（s），ByVal 0& 0，vbNullString，ByVal 0&）
 
如果ccb = 0然后
 Err.Raise 5，内部错误。 
 End If 
 
 Dim b（）As Byte 
 ReDim b（1 to ccb）// ERROR TYPE MISMATCH on ccb 
 
如果WideCharToMultiByte（CP_UTF8 ，0，StrPtr（s），Len（s），b（LBound（b）），ccb，vbNullString，ByVal 0&）= 0然后
 Err.Raise 5，内部错误。 
 Else 
 ToUTF8 = b 
如果
 
结束函数
  

感谢您的帮助。

  Private Const CP_UTF8 As Long = 65001 
  

到

 私有Const CP_UTF8 = 65001 
  

---

这个

 code> Private Const ERROR_INSUFFICIENT_BUFFER As Long = 122& 
  

至

  Private Const ERROR_INSUFFICIENT_BUFFER = 122& 
  

---

这个

  Dim ccb As LongPtr 
  

/ p>

  Dim ccb As Variant 
  

在我建议的最后三个chnages中，我们将它们声明为Variants，因为我们不知道在不同系统上的类型。它将是 Long 或 LongPtr

I should figure out problem with excel VBA code compatibility on 64bit systems. I do not use VB language and code below is not my but I have to solve that issue.

Excel VB code:

Option Explicit

Private Declare Function WideCharToMultiByte Lib "kernel32.dll" (ByVal CodePage As Long, ByVal dwFlags As Long, ByVal lpWideCharStr As Long, ByVal cchWideChar As Long, ByRef lpMultiByteStr As Byte, ByVal cchMultiByte As Long, ByVal lpDefaultChar As String, ByRef lpUsedDefaultChar As Long) As Long

Private Const CP_UTF8 As Long = 65001
Private Const ERROR_INSUFFICIENT_BUFFER As Long = 122&


Public Function ToUTF8(s As String) As Byte()

  If Len(s) = 0 Then Exit Function


  Dim ccb As Long
  ccb = WideCharToMultiByte(CP_UTF8, 0, StrPtr(s), Len(s), ByVal 0&, 0, vbNullString, ByVal 0&)

  If ccb = 0 Then
    Err.Raise 5, , "Internal error."
  End If

  Dim b() As Byte
  ReDim b(1 To ccb)

  If WideCharToMultiByte(CP_UTF8, 0, StrPtr(s), Len(s), b(LBound(b)), ccb, vbNullString, ByVal 0&) = 0 Then
    Err.Raise 5, , "Internal error."
  Else
    ToUTF8 = b
  End If

End Function

I have tried to add conditions #If VBA7 and PtrSave to everywhere but worksheet still does not work.

This is the code that I tried in Office 64 Bit

    Option Explicit

    #If VBA7 Then
    Private Declare PtrSafe Function WideCharToMultiByte Lib "kernel32" (ByVal CodePage As Integer, ByVal dwFlags As Long, ByVal lpWideCharStr As LongPtr, ByVal cchWideChar As Long, ByVal lpMultiByteStr As Long, ByVal cchMultiByte As LongPtr, ByVal lpDefaultChar As Long, ByVal lpUsedDefaultChar As Long) As LongPtr
    #Else
Private Declare Function WideCharToMultiByte Lib "kernel32.dll" (ByVal CodePage As Long, ByVal dwFlags As Long, ByVal lpWideCharStr As Long, ByVal cchWideChar As Long, ByRef lpMultiByteStr As Byte, ByVal cchMultiByte As Long, ByVal lpDefaultChar As String, ByRef lpUsedDefaultChar As Long) As Long
    #EndIf

    Private Const CP_UTF8 As Long = 65001
    Private Const ERROR_INSUFFICIENT_BUFFER As Long = 122&


    Public Function ToUTF8(s As String) As Byte()

      If Len(s) = 0 Then Exit Function


      Dim ccb As LongPtr
      ccb = WideCharToMultiByte(CP_UTF8, 0, StrPtr(s), Len(s), ByVal 0&, 0, vbNullString, ByVal 0&)

      If ccb = 0 Then
        Err.Raise 5, , "Internal error."
      End If

      Dim b() As Byte
      ReDim b(1 To ccb) // ERROR TYPE MISMATCH on ccb

      If WideCharToMultiByte(CP_UTF8, 0, StrPtr(s), Len(s), b(LBound(b)), ccb, vbNullString, ByVal 0&) = 0 Then
        Err.Raise 5, , "Internal error."
      Else
        ToUTF8 = b
      End If

    End Function

Thanks for help.

This

Private Const CP_UTF8 As Long = 65001

To

Private Const CP_UTF8 = 65001

This

Private Const ERROR_INSUFFICIENT_BUFFER As Long = 122&

To

Private Const ERROR_INSUFFICIENT_BUFFER = 122&

---

This

Dim ccb As LongPtr

To

Dim ccb As Variant

In the last three chnages that I suggested, we are declaring them as Variants because we don't know what the type will be on different systems. It will either be Long or LongPtr
