Open embedded Textfile using Notepad

I have the following problem. I want to open an embedded textfile (agb.txt) using "notepad.exe". I've got the following code:

private void linkLabel4_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
   string editorPath = Environment.SystemDirectory + "\\notepad.exe";
   var startInfo = new ProcessStartInfo(editorPath)
   {
      //Start Maximized
      WindowStyle = ProcessWindowStyle.Maximized,
      Arguments = "agb.txt"
   };
   //Start notepad.exe (agb.txt)
   Process.Start(startInfo);
}

When I start the program and click the Linklabel, Notpad.exe open up but can't find the embedded file (obviously). So is there a kinda 'Workaround'?

You can start Nodepad.exe and then "send" the text from the embedded file to it. Instead of my hardcoded string, you would read the content of the file into a string and then call DoSendMessage(stringWithYourFileContent);

This question and answer is a good resource for reading the content of the embedded file: How to read embedded resource text file

class Program
{
    [DllImport("user32.dll", EntryPoint = "FindWindowEx")]
    public static extern IntPtr FindWindowEx(IntPtr hwndParent, IntPtr hwndChildAfter, string lpszClass, string lpszWindow);

    [DllImport("User32.dll")]
    public static extern int SendMessage(IntPtr hWnd, int uMsg, int wParam, string lParam);



    static void Main(string[] args)
    {
        DoSendMessage("Sending a message, a message from me to you");
    }



    private static void DoSendMessage(string message)
    {
        Process notepad = Process.Start(new ProcessStartInfo("notepad.exe"));
        notepad.WaitForInputIdle();

        if (notepad != null)
        {
            IntPtr child = FindWindowEx(notepad.MainWindowHandle, new IntPtr(0), "Edit", null);
            SendMessage(child, 0x000C, 0, message);
        }
    }
}

The constant 0x000c of SendMessage is documented here http://msdn.microsoft.com/en-us/library/windows/desktop/ms632644(v=vs.85).aspx . The constant says SETTEXT which really means that the text in notepad will be replaced if you send more than one message using this constant.

What about saving the file to %TEMP% and then simply calling

Process.Start(@"c:\temp\agb.txt");

(this will actually open the file in whatever application is registered to load it)
