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

Well I thought that, until I tried. The CEdit Control turns Gray if you make it 'Read Only', and limits to 32757 lines. Try a ListBox instead, and you are limited to 32757 lines, and you have to implement the Edit\Copy Interface and Selection Interface yourself. Notepad has None of these limitations, but allows a User to Modify and save. Googeling the question results in solutions which pride themsevelves in advanced Editing features, exactly what I Do NOT want! Hence the Question. Regards, :)

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).

You should get him to add file/open functionality instead of just drag/drop. The Express Edition of C# is, however, free.

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.

*grin* yes, I am just saying that the tool to compile the code he gave you, is quite free for you to download and thus make the app work as you want.

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. :)

Is the 32757 line limit a major issue ? Because the rest seems easy to deal with. Just don't make it read only, but write code to reject all keypresses.
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?

It takes VS 2008 20 seconds to start on my machine, and at least 8 seconds to compile the most basic app....

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.

All our Code is in MFC. We do not use Managed Code.
Bram van Kampen
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....
