1 Public Shared connstr As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source1=" & Application.StartupPath & "\data\Sale.mdb"（这条语句连接能对数据库进行添加和修改都无误）
但当我换成以下的两条条语句则都只能对access数据库进行查找，当对access数据库进行添加或修改则会出现错误提示
2 Public Shared connstr As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\192.168.0.56\data\Sale.mdb;Persist Security Info=false"
3 Public Shared connstr As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Z:\Sale.mdb;Persist Security Info=false"


你连错误提示都不发怎么解答
