删除 __________________________________________________________________________ myConnection.ConnectionString = "Server=localhost;database=Experts;User ID=sa;Password= " 这一句后面加入 myConnection.Open() 试试，可以是连接没打开的原因。当然最好在 End Sub 前
加上 myConnection.Close() __________________________________________________________________________
