Question

I’m working on a VB.NET Program that inputs data to a SQL Server CE local database (*.sdf file).

My code is this:

    Imports System.Data.SqlClient
    Public Class Form1
    Dim myConnection As SqlConnection
    Dim myCommand As SqlCommand
    Dim ra As Integer

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        myConnection = New SqlConnection("Data Source= Database1.sdf")
        myConnection.Open()
        myCommand = New SqlCommand("Insert into website('"TextBox1.Text"')", myConnection)
        ra = myCommand.ExecuteNonQuery()
        MessageBox.Show("Updated")
        myConnection.Close()
    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        TextBox1.Text = My.Settings.SaveWebsite
    End Sub
End Class

I get three errors during compile:

Error 1:
Argument not specified for parameter ‘connection’ of ‘Public Sub New(cmdText As String, connection As
System.Data.SqlClient.SqlConnection, transaction As
System.Data.SqlClient.SqlTransaction)’.

Error 2
Comma, ‘)’, or a valid expression continuation expected.

Error 3
Value of type ‘System.Data.SqlClient.SqlConnection’ cannot be converted to ‘System.Data.SqlClient.SqlTransaction’.

This is first time I am using VB.NET and I’m hoping someone might know what I’m doing wrong here.

Thanks in advance

Answer 1

Well, for starters: when targeting SQL Server Compact Edition (the *.sdf file), you need to use SqlCeConnection and SqlCeCommand (not SqlConnection or SqlCommand – those are for the full-blown SQL Server, non-compact)

Secondly: your INSERT statement is incorrect – the correct SQL syntax would be:

INSERT INTO Table (col1, col2, ..., colN) 
VALUES(val1, val2, ..., valN)
