我要用ASP.NET(VB)寫個網頁可讓使用者登入及註冊的程式
但不知哪裡錯?
已註冊頁面為例，點下註冊button後之事件：
Dim Conn As SqlConnection = New SqlConnection("server=.\SQLEXPRESS;uid=test;pwd=800106;database=master")
Conn.Open()
Dim sqlstr As String = "Insert Into user_profile Values('&txtusername.Text&','&txtpassword.Text&','&txtnickname.Text&','&txtrealname.Text&','&txtemail.Text&')"
Dim cmd As New SqlCommand(sqlstr, Conn)
cmd.ExecuteNonQuery()

cmd.Cancel()
Conn.Close()
Conn.Dispose()
以上...
覺得是錯在連線字串?
連線字串裡到底要怎麼寫才對呢?以下三種寫法都還是錯...
1. Dim Conn As SqlConnection = New SqlConnection("Data Source=(localdb)\v11.0;AttachDbFilename=DataDirectory|db.mdf;Integrated Security=True")

2. Dim Conn As New SqlConnection("Data Source=(localdb)\v11.0;Integrated Security=SSPI;Initial Catalog=master")

3. Dim Conn As SqlConnection = New SqlConnection("Server=.\SQLEXPRESS;Database=master;User Id=test;Password=800106")
