    A TextBox??? Geez! That's limited to 64 KB or around that. Can't believe you didn't use a RichTextBox. Shame on you. Now you'll get featured in the Coding Horrors forum ;P

    Windows ME has a limit of 64K. For others, the limit is 4GB. Since nobody uses ME, I'd say the real limit is 4GB. :)

        You can use a rich text control and make it read only. It can display really large text files (once you get too large it will be very slow).

        Yes, for the number of lines he's talking about, I think a smarter solution is needed than to just put it all into a RTB.

          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.

          FYI, if you turn off Word Wrap, it will load faster. And I think Word Pad will load any text file instantly. Though, like you say, it facilitates modification. Perhaps you could experiment with setting the files as readonly?

              Really? It depends on what you call basic, but that's way too slow - on my laptop, compiling a project with ~10 files takes 2-3 seconds, max.

                Yes, that's well spotted. However for the purpose I want to use it, I would pass the File Open info through the 'Environment', and default to an error screen, if someone just doubleclicked on it in windows explorer, they should get an eror message stating that is NOT a Stand Alone Application.

                  If you want to create an app yourself and you don't want to use managed code, just allow the user to page through the file in 32KB chunks. Create a right arrow button that will go the next 32K and a left arrow button that will go to the previous 32K. And maybe allow the user to specify how many bytes into the file to start the loading. There are more sophisticated techniques, but that shouldn't take too long to code.

                      6 secs to start and populate the Start page (don't ask me why I haven't disabled that, I don't know why.) Compiling is OK but I don't work on large projects....

                                Even simpler: Keep it readonly, intercept the WM_CTLCOLOR message, set the device context's background color to white, and return a white HBRUSH.

                                  Just going by what's been described, wouldn't it be easier (and safer) to configure the file security to disallow modifications instead? Use any text editor you want at that point and save is disabled. It also means that people that decide not to use your text editor (because some people are sneaky that way :P) still can't edit.

                                      Any Web Browser? The saving bit though... Perhaps a winform with an IE control with saving disabled? //L

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

                                        Try the DAMN NFO viewer, meant for viewing, but not editing, NFO and DIZ, but does TXT as well. WW

                                          I just skimmed earlier posts prior to posting mine, it seemed someone mentioned some limitations with textboxes. I admitedly have no clue if they are accurate, I haven't done winform dev for aaaaages. That said, a multiline readonly textbox (assuming text length limitation prognoses is incorrect) would be sexier. And I'm all for sexier. //L
