VBA不断尝试引用SQL数据库时出错
我的程序基本上打开任何.MDB文件，然后显示在电子表格中的文件，但是我不断收到此错误（尽pipe代码工作，并在Excel中打开文件）。
出现的错误是“运行时错误429，Active X组件无法创build对象”
这里是我有的代码，我会写在上面，当我点击debugging时突出显示的行。
Option Explicit Private Sub CommandButton1_Click() Dim strFileToOpen As String ChDir ThisWorkbook.Path strFileToOpen = Application.GetOpenFilename _ (Title:="Please choose a file to open", _ FileFilter:="All Files *.* (*.*),") Workbooks.Open fileName:=strFileToOpen frmMain.TextBox1.Text = strFileToOpen Exit Sub End Sub Private Sub CommandButton2_Click() Dim fileName As String Dim copyDestination As String Dim copyFile As String Dim fso If frmMain.TextBox1.Value = "" Then MsgBox "No File Selected" Else fileName = frmMain.TextBox1.Value copyDestination = ThisWorkbook.Path & "\Sales_Orders.mdb" Set fso = CreateObject("Scripting.FileSystemObject") fso.copyFile fileName, copyDestination, True Set fso = Nothing MsgBox "File copied to current workbook directory!" End If 'SQL Statements Dim db As Database Dim qdef As QueryDef Dim td As TableDef Dim dbname As String ' Open the database. replace "c:\DBfile.mdb" with your ' database file name '当我debugging时，这行设置DB = OPENDATABASE被突出显示
Set db = OpenDatabase(copyDestination) ' List the table names. For Each td In db.TableDefs ' if you want to display also the system tables, replace the line ' below with: List1.AddItem td.Name If td.Attributes = 0 Then ListBox1.AddItem td.Name Next td db.Close End Sub Private Sub CommandButton3_Click() Unload Me End Sub
如代码中所述，Set db = OpenDatabase（copyDestination）是当我点击debugging时突出显示的行。 任何想法为什么这是怎么回事？
OpenDatabase方法是Workbooks对象的成员。 如果没有对Workbooks对象的引用，就不能特别调用它。
Dim db as Object Set db = Workbooks.OpenDatabase(copyDestination)
将db声明为对象，而不是数据库。
