Forms PtrSafe属性错误MS访问

我试图将记录输入MS Access表单，但出现以下编译错误：

“此项目中的代码必须更新才能在64位系统上使用。请检查并更新Declare语句，然后用PtrSafe属性标记它们。”

数据库中的代码如下所示：

Private Sub cboProjectID_Change()
    Dim VarComboKey As Integer

    VarComboKey = Me.cboProjectID.Value

    Me!cboErrCod1.RowSource = "SELECT DISTINCT [Error_Reason_Code], [Reason_Code_Desc] FROM [HDR_ErrCodes] WHERE [project_ID] = " & VarComboKey
    Me!cboErrCod2.RowSource = "SELECT DISTINCT [Error_Reason_Code], [Reason_Code_Desc] FROM [HDR_ErrCodes] WHERE [project_ID] = " & VarComboKey
    Me!cboErrCod3.RowSource = "SELECT DISTINCT [Error_Reason_Code], [Reason_Code_Desc] FROM [HDR_ErrCodes] WHERE [project_ID] = " & VarComboKey
    Me!cboErrCod4.RowSource = "SELECT DISTINCT [Error_Reason_Code], [Reason_Code_Desc] FROM [HDR_ErrCodes] WHERE [project_ID] = " & VarComboKey
    Me!cboErrCod5.RowSource = "SELECT DISTINCT [Error_Reason_Code], [Reason_Code_Desc] FROM [HDR_ErrCodes] WHERE [project_ID] = " & VarComboKey
End Sub

Private Sub Form_BeforeUpdate(Cancel As Integer)


   Dim ctl As Control

   On Error GoTo Err_BeforeUpdate


   If Me.Dirty Then

      If MsgBox("Do you want to save?", vbYesNo + vbQuestion, _
              "Save Record") = vbNo Then
         Me.Undo
      End If
   End If

Exit_BeforeUpdate:
   Exit Sub

Err_BeforeUpdate:
   MsgBox Err.Number & " " & Err.Description
   Resume Exit_BeforeUpdate
End Sub

有人能帮我更新代码以防止出现此错误吗？

经过一番搜索，我找到了declare语句所在的位置。此代码修复了它：

  #If VBA7 Then
       Private Declare PtrSafe Function GetTickCount Lib "kernel32" () As Long
       #Else
       Private Declare Function GetTickCount Lib "kernel32" () As Long
       #End If

这并不是全部代码。你已经在某处声明了。
