[VB.NET] Inserire record con istruzione SQL

[x69asterix]

SqlCeException
Application:Run+0xf
Form1:Main+=xd

Ma così è corretto? cioè, crea la tabella è inserisce?

    Private Sub cmdCreate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdCreate.Click
        Dim create As String

        If (System.IO.File.Exists(db)) Then
            System.IO.File.Delete(db)
        End If

        Try
            Dim eng As SqlCeEngine
            eng = New SqlCeEngine("Data Source=" + db)
            eng.CreateDatabase()

            create = "CREATE TABLE UgiUser(Firstname nvarchar(10) PRIMARY KEY not null,Surname nvarchar(20) not null,Age int not null)"
            ExecSql(create)
            ExecSql("INSERT INTO UgiUser VALUES ('" & Me.txtName.Text & "','" & Me.txtSurname.Text & "','" & Me.txtAge.Text & "')")
            
            MsgBox("Table UgiUser created.")

        Catch exc As SqlCeException
            MsgBox(exc.Message)
        End Try
    End Sub
