大家帮忙给我修改下路径，修改为相对的，vb.net连接access数据库

vb.net access数据库 绝对路径修改相对路径 图书管理系统 --------------------编程问答-------------------- 将图书管理系统数据库.mdb放到exe同目录下
"图书管理系统数据库.mdb" --------------------编程问答-------------------- 不行啊，能不能帮我修改下代码 --------------------编程问答--------------------
如1l所说，将图书管理系统数据库.mdb放到exe同目录下
然后数据库路径是application.startpath&"\数据库名.mdb"; --------------------编程问答-------------------- 我这样修改了 App.Path = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Application.startpath("\1图书管理系统数据库.mdb") & ";Persist Security Info=False"
报错说 “startpath”不是“System.Net.Mime.MediaTypeNames.Application”的成员。
--------------------编程问答-------------------- App.Path = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Application.startpath & ("\1图书管理系统数据库.mdb") & ";Persist Security Info=False" --------------------编程问答-------------------- 按您所述，任出现错误， Application.startpath属于什么组件 --------------------编程问答-------------------- C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Windows.Forms.dll
属于这个组件
Public NotInheritable Class Application
Inherits System.Object
System.Windows.Forms 的成员
摘要:
提供 static 方法和属性以管理应用程序，例如启动和停止应用程序、处理 Windows 消息的方法和获取应用程序信息的属性。无法继承此类。
--------------------编程问答-------------------- App.Path = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Application.startpath & ("\1图书管理系统数据库.mdb") & ";Persist Security Info=False"
你怎么把路径(App.Path这个在NET里有用吗？就算有用，能赋值吗？)直接写到数据库的连接字符串里去了。。？
还有，你这怎么有个App.Path，这个是vb6.0的写法，net的写法是Application.startpath
这两者在各自的环境里面，作用是一样的。都是取本EXE所在的目录。
你前面那个app.path绝对不对。
一般，连接字符串，我给你看看我的，现成的！
LianJie = "provider=microsoft.jet.oledb.4.0;data source=" & Application.StartupPath & "\HM.mdb" '/*定义连接字符串*/
用的时候，直接
Dim CN As OleDbConnection
CN = New OleDbConnection(LianJie)
然后cn.open，就连上去了。
--------------------编程问答-------------------- 但是你在这么做之前，必须先把你那个1图书管理系统数据库.mdb放在你的EXE相同的位置，当你调试的时候，那个EXE是在debug文件夹里面的。。 --------------------编程问答-------------------- 积分不够，真难受，来评价一下，赚点积分。 --------------------编程问答-------------------- 前面好像有错误：应该是StartupPath而不是startpath
补充：.NET技术 , VB.NET
