Text Viewer

Hi, Does anyone know of a Text Viewer, (for basic .txt Files) which does NOT facilitate editing or Saving. :)

http://www.textpad.com but open the file in read only mode. Even in read/write mode, I've opened 16mb files before with little decrease in speed.

Yes, it is! We have Basic Log Files, which record transactions in ASCII, and which would cover up to six years of trading. The biggest sofar contans 425,000 lines. it is not accessed very frequently, but, the concern is that we have no tool to access it which disallows modification. Notepad loads it Sofar No Problems, it Takes a Long Time, No Problem, but it facilitates modification.

Can you just make the file read-only?

I'm with Don M. For reading looooooong log files you want a version of Tail http://en.wikipedia.org/wiki/Tail\_(Unix)

Cygwin "less"? It's a file viewer with navigation and string search. It has no editing features directly, but there's a way to get into the vi editor from it. It might be possible to disable that or maybe it just doesn't work if the editor isn't installed? If you had to, you might be able to get the source and disable the command for entering the editor. Less should load such a large file pretty quickly, though I don't think I've tried it on anything quite that big. Not in recent memory, anyway (I tend to use vim for viewing my large log files). Also, vim also has a read-only mode that you can specify from the command line, but I can't recall if there's any way to orderride it and write changes back to the original file. Even if you can't, you can still modify the file and write your modified copy to a different file.

How about something like dman nfo viewer? I haven't tried loading large things with it, but it might fit your bill.

This may be an overly simple response, or it may not factor in you organizations security concerns which may or may not be unique. Why not just post the files some where and view them in a web browser, and disallow editing on the server end... Ie r--r--r-- permissions. I would imagine this would involve a very simple script to copy the files, and a very simple page to display a list of the files. Additionally I would make a note that a web browser can be launched from your executable as required.

The one I switched to when Vern Buerg dropped the ball on a Windows version of his program "list," is called "V." You can find it at fileviewer.com, and it's very inexpensive and works very well. I've been using it for more than 15 years. Rick

It seems like everyone is taking a much too difficult approach to answer the original post. (sorry, hadn't seen the full thread) There are, in fact, several viewer applications that will open a text file for viewing but not editing. Here's a couple: Universal Viewer Free[^] Large Text File Viewer[^] And from the same collection site, here's a couple categories that might have something else that could work for you: Text Viewers[^] and Document Viewers[^]. Hope that helps! :-D

Any browser will read text as read only, but I have never tried on big files. If you make the directory read only for the users, but write access for the program that makes the log files, you can use any text viewer/editor. Textpad is much faster than Notepad, and it also has a useful search function plus many other features. -Ulf

"cat" or "type" depending on OS.

Use the RichTextBox control in VS and make it ReadOnly this will load very large text files for viewing only..

Yeah there is. The plan was to throw in the necessary cleanup, allow "pinning" projects etc. I hoped that with HTML as layout engine, some javascript with access to DTE, ShellExecute and environment variables, I could throw together a decent start page replacement. However, reality is that this is a pain - everything is just incomplete and requires tons of extra work. Not sure if it's worht following through with it - but at least I learnt a tinyl little bit of Javascript, and cleaned up some libraries.
Agh! Reality! My Archnemesis![^]
