i have a windows forms with 7 texboxes, i would like to save the input into a sqwl databse , but i am having a bit of problem, this is my code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

    Dim con As New SqlConnection("server = GX520B\SQLEXPRESS;Initial Catalog=return;Integrated Security=True")

    Dim cmd As New SqlCommand("insert into dbo.RMA (Rma_Number,Vendor,Device,Serial_Number,Model,Problem,Date) values (@Rma_Number,@Vendor,@Device,@Serial_Number,@Model,@Problem,@Date)")
    cmd.Connection = con
    con.Open()
    cmd.Parameters.AddWithValue("@Rma_number", Me.TxtRMA.Text)
    cmd.Parameters.AddWithValue("@Vendor", Me.TxtVendor.Text)
    cmd.Parameters.AddWithValue("@Device", Me.TxtDevice.Text)
    cmd.Parameters.AddWithValue("@Serial_Number", Me.TxtSN.Text)
    cmd.Parameters.AddWithValue("@Model", Me.TxtModel.Text)
    cmd.Parameters.AddWithValue("@Problem", Me.TxtProblem.Text)
    cmd.Parameters.AddWithValue("@Date", Me.TxtDate.Text)

    Dim reader As SqlDataReader = Nothing


    cmd.ExecuteNonQuery()

    con.Close()

end sub
i am getting the error:
Invalid column name serial_number

Comments
Please move to vb.net thanx

Sorry for the obvious, but are you sure the field is called "Serial_Number"?

Instead of using parameters try it with the text boxes it self....

Dim cmd As New SqlCommand("insert into dbo.RMA values ('"+TxtRMA.Text+"','"+TxtVendor.Text+"','"+TxtDevice.Text+"','"+TxtSN.Text+"','"+TxtModel.Text+"','"+TxtProblem.Text+"','"+TxtDate.Text+"')")
