vb 与access数据库编程，打包运行，在好几台计算机上测试都没有问题，唯独一台计算机上出现运行时错误’-2147217900(80040e14)’未知，发现问题出现如下代码上，请高人帮我解决一下，谢谢！
Dim sql As String
Dim connectionstring As String
connectionstring = "provider=microsoft.jet.oledb.4.0;data source=" & App.Path & "\zygl.mdb"
conn.Open connectionstring
If Trim(txtUserName.Text) = "" Then
MsgBox "请输入用户名", vbOKOnly + vbExclamation
txtUserName.Text = ""
txtUserName.SetFocus
ElseIf txtPassword.Text = "" Then
   MsgBox "请输入密码", vbOKOnly + vbExclamation
   txtPassword.Text = ""
   txtPassword.SetFocus
Else
   sql = "select * from [yh] where [用户名]='" & txtUserName.Text & "'"
   rs_login.Open sql, conn, adOpenKeyset, adLockPessimistic
   If rs_login.EOF = True Then
     MsgBox "对不起，没有这个用户", vbOKOnly + vbExclamation
     txtUserName.Text = ""
     txtUserName.SetFocus
     rs_login.Close
     Set rs_login = Nothing: Set conn = Nothing

没有明白你的意思

#3

不是没有安装access的问题
