我使用此代码链接到另一个后端文件(例如,如果我交付并且后端不在同一个地方,就像它很少那样)
Public Function AttachToAnotherDataFile() As Boolean
On Error GoTo 0
Dim ofd As FileDialog
Dim result As VbMsgBoxResult
Set ofd = FileDialog(msoFileDialogFilePicker)
ofd.show
If ofd.SelectedItems.Count = 1 Then
result = RelinkLinedTablesToBackend(ofd.SelectedItems(1))
If result = vbCancel Then
AttachToAnotherDataFile = False
End If
AttachToAnotherDataFile = True
Else
AttachToAnotherDataFile = False
End If
End Function
Function RelinkLinedTablesToBackend(backendPath As String) As VbMsgBoxResult
Dim tdf As TableDef
Dim db As Database
Dim tdfRefresh As TableDef
Set db = CurrentDb
For Each tdf In CurrentDb.TableDefs
If tdf.Connect <> vbNullString Then
On Error Resume Next
db.TableDefs(tdf.Name).Connect = ";DATABASE=" & backendPath
db.TableDefs(tdf.Name).RefreshLink
If Err.Number <> 0 Then
RelinkLinedTablesToBackend = MsgBox(Err.Description, vbCritical + vbRetryCancel, "Error #:" & Err.Number)
Exit Function
End If
On Error GoTo 0
End If
Next
Set tdf = Nothing
Set db = Nothing
End Function
然后,当我在数据库打开时打开默认表单时,我尝试连接到后端
On Error Resume Next
Dim rs As DAO.Recordset: Set rs = CurrentDb.OpenRecordset("Select Username, Password, UserGroup FROM Users")
If Err.Number = 3024 Or Err.Number = 3044 Then
MsgBox Err.Description & vbNewLine & "You will be prompted next to locate the data file. Without this file the database cannot open." _
, vbCritical + vbOKOnly, "Backend Data File Not Found"
GoTo FindBackEndFile
End If
