在自已的程序中如何备份数据库？

[xiaoxingchi]

已经打开了一个数据库，现在我要把这个数据复制一份。

用copyfile spath dpath

可是说不能存权，怎么解决！？

这样，用SQL来实现
Dim sql As String, rs As New ADODB.Recordset
sql = "Backup database jxc to Disk='" & SaveUrl & "'"
Set rs = Conn.Execute(sql)
Set rs = Nothing
Gadocn_app.Close

[cmsoft]

Conn.Close

上面这句打错了

简单的方法使用API
Private Declare Function CopyFile Lib "kernel32" Alias "CopyFileA" (ByVal SFile As String, ByVal DFile As String, ByVal Bool As Long) As Long
'如果在Bas文件可以把Private 去掉
Private Sub Command1_Click()
Dim b As Long
Dim x As Long
x = CopyFile("c:\temp\dn.mdb", "c:\temp\dn2.mdb", b)
End Sub
在你打开数据库后使用CopyFile就可以了
