当Access文件大于指定的大小时就自动压缩

Public Function AutoCompactCurrentProject()
Dim fs, f, s, filespec
Dim strProjectPath As String, strProjectName As String
strProjectPath = Application.CurrentProject.Path
strProjectName = Application.CurrentProject.Name
filespec = strProjectPath & "/" & strProjectName
Set fs = CreateObject("Scripting.FileSystemObject")
Set f = fs.GetFile(filespec)
s = CLng(f.Size / 1000000) ‘转换文件大小为MB
If s > 20 Then ‘修改此处的20M为你自己需要的值
Application.SetOption ("Auto Compact"), 1 ‘压缩程序
Else
Application.SetOption ("Auto Compact"), 0 ‘不压缩程序
End If
End Function
