Posts: 113              so I want to read in a text file and i used

Code:dim myfile as folderitem
dim input as textinputstream

myfile=getfolderitem(FILENAME)
if myfile<>nil then
  input=myfile.openastextfile
  if input<>nil then
  **STUFF**
  else
  editfield1.text="nil input"
  end if
else
  editfield1.text="no file"
end if


so the editfield reads nil input.  I therefore conclude that the program found 
the file since myfile<>nil is true.  I know the file contains about 300 lines 
of text because i can open it in my text  editor.  so why is the openastextfile 
property of myfile returning nil?
