May be a little ugly but: System.DateTime dtYesterday; dtYesterday = System.DateTime.Now.AddHours(-24);

FileStream fs = new FileStream(path, FileMode.Open); StreamReader sr = new StreamReader(fs); StreamWriter sw = new StreamWriter(fs); sr.ReadToEnd(); sr.Close(); sw.Close(); fs.Close(); Closing the streamreader before initializing the streamwriter causes a Stream was not writable. error. Keep the reader and writer open until you close the file.

Try opening the file as a filestream, and then passing the filestream handle to the streamreader and writer.

A little unclear with what you are trying to do. Try using the BringToFront and SendToBack Functions if you are wanting to change the z-order of the form.

The method I use to handle this sort of event would be the keydown or one of the other key events (keypress/keyup). Just check the corresponding arguments (Such as keycode) http://msdn2.microsoft.com/en-us/library/system.windows.forms.control.keydown.aspx[^]
