VB.NET Notepad

HI Experts

I have an SQL that writes to a ComboBox can you explain how to write it to the combobox and open notepad and write to it so customer doesn't need to cut and paste from combo to notepad

Dim Sql As String = String.Format("SELECT TABLE_NAME FROM INFORMATION_SCHEMA.tables ORDER BY TABLE_NAME")
            Dim reader As Data.IDataReader = DataConnector.GetReader(Sql, Nothing)
            Do While reader.Read = True
                mTablesComboBox.Items.Add(reader.GetString(0))
            Loop

It is unclear what you mean by notepad. Is it Windows Notepad.exe you want to write to? Is it a notepad control within your application?
If it is the former you can create a temp text file, fill it with the table names from your SQL query and then open it with Notepad.exe using Process.Start

Sorry its Windows notepad

the SendMessage(notepad.MainWindowHandle, WM_SETTEXT, IntPtr.Zero, texttoadd) sends nothing
I tried SendKeys.SendWait(texrttosend) sends some info not all and sometimes exits the program
there may be up to 50 fields in the table I want them on separate lines how do you  populate the notepad or is the only way is to create a text file and open it. I would rather send direct but if a temp file is the only way how do you open It in the notpad with out using file open

Const WM_SETTEXT As Integer = &HC
        <DllImport("user32.dll")> _
        Private Shared Function SendMessage(ByVal hWnd As IntPtr, ByVal Msg As Integer, ByVal wParam As IntPtr, <MarshalAs(UnmanagedType.LPStr)> ByVal lParam As String) As IntPtr
        End Function

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

            Dim npad As ProcessStartInfo = New ProcessStartInfo("NotePad.exe")
            npad.UseShellExecute = True

            Dim notepad As Process = Process.Start(npad)
            Dim texttoadd As String = ""

            Dim sql As String = "Select column_name from information_schema.columns where table_name = @TableName order by column_name"
            Dim params As New DataParameterCollection("@TableName", "Employee")
            Using dataConnector As IDataConnector = DataUtils.GetDataConnector()
                Dim reader As Data.IDataReader = dataConnector.GetReader(sql, params)
                Do While reader.Read = True
                    texttoadd = vbLf & reader.GetString(0)
                    SendMessage(notepad.MainWindowHandle, WM_SETTEXT, IntPtr.Zero, texttoadd)
                Loop
                reader.Close()
            End Using
        End Sub
    End Class
