請教一下，我看不懂下面在做什麼動作
Dim WithEvents rs As Recordset 'WithEvents-這是什麼意思
Set rs = New Recordset
rs.Open sqlstr, con, adOpenDynamic, adLockOptimistic
Set DataGrid1.DataSource = rs '指派rs.Open 給DataGrid1(不懂)
Dim WithEvents rs As Recordset 'WithEvents-這是什麼意思
Set rs = New Recordset
rs.Open sqlstr, con, adOpenDynamic, adLockOptimistic
Set DataGrid1.DataSource = rs '指派rs.Open 給DataGrid1(不懂)
