在这里徘徊一点。尝试开发将用户输入链接到我的数据库的代码,以书目记录的形式。例如,用户会被要求输入他们的姓名地址等等。但我使用的代码似乎并没有执行,因为我不断得到相同的错误。如何通过VB'插入'数据到数据库中
Line 12: Dim con As New SqlConnection
Line 13: Dim inscmd As New SqlCommand
Line 14: con.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings("Database.My.MySettings.Database1ConnectionString1").ConnectionString
Line 15: con.Open()
Line 16: inscmd.CommandText = ("insert into booking values('" + txtfirstname.Text + "', " + txtSurname.Text + "', " + txtAddressline1.Text + "', " + txtAddressline2.Text + "', " + txtPostcode.Text + "', " + txtTime.Text + "', " + txtPeople.Text + "', " + txtDropoff1.Text + "', " + txtDropoff2.Text + "', " + txtDropoffpost.Text + "")
这是第14行,包含错误,但我不知道为什么。这是我的代码;
Protected Sub btnsubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnsubmit.Click
Dim con As New SqlConnection
Dim inscmd As New SqlCommand
con.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings("Database.My.MySettings.Database1ConnectionString1").ConnectionString
con.Open()
inscmd.CommandText = ("insert into booking values('" + txtfirstname.Text + "', " + txtSurname.Text + "', " + txtAddressline1.Text + "', " + txtAddressline2.Text + "', " + txtPostcode.Text + "', " + txtTime.Text + "', " + txtPeople.Text + "', " + txtDropoff1.Text + "', " + txtDropoff2.Text + "', " + txtDropoffpost.Text + "")
Print(inscmd.CommandText)
inscmd.Connection = con
inscmd.ExecuteNonQuery()
con.Close()
inscmd.Parameters.Clear()
MsgBox("Your booking has been successfully")
con.Close()
End Sub
什么错误?您的web.config中的连接字符串实际上是否称为“Database.My.MySettings.Database1ConnectionString1”? – 2013-04-29 13:17:09
ConnectionString“connectionString =”Data Source =。\ SQLEXPRESS; AttachDbFilename = | DataDirectory | \ Database.mdf; Integrated Security = True; User Instance = True“providerName =”System.Data.SqlClient“/>这就是它所说的我的web配置文件? – AmyLouise 2013-04-29 13:26:52
