Thanks But if the filetype is not registered an error occur. Can i view the 'Open With...' dialog

Use ProcessStartInfo and set UseShellExecute and ErrorDialog both to true:

ProcessStartInfo info = new ProcessStartInfo();
info.FileName = myTextBox.Text;
info.UseShellExecute = true;
info.ErrorDialog = true;
Process.Start(info);

Be sure to read the class documentation for additional members to see what other features exist.

One way to do this is to use System.Diagnostics.Process... using System.Diagnostics; . . . // // opens an instance of notepad with the file c:\mytest.xsd // private void OpenTheFileInNotepad(string fileName) { Process.Start("notepad.exe",fileName); } see MSDN at: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemDiagnosticsProcessClassTopic.asp
