Hi, Looks Fine. However I cannot compile that. Could you send me a Compiled version of that? I'll include you in the Credits. (Better: Include your Contribution in the Compiled Version) email: bramvankampen@aol.com :) :) :) regards

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

Does it allow more than 32767 lines ? It occured to me that part of of the issue could be that the op didn't want managed code, and that it would be tricker with the older MFC controls perhaps.

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

Haha, I'm done with charity for the day. Maybe you'd like to incorporate Syslog exception logging, printing functionality, syntax highlighting, layout settings, and so on?

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.

Hmmm... if I was going to read 425,000 lines of text, I expect I'd offer search throughout the entire document, but I would not present it all to the user, I'd page it, and/or show as much as I got out of a search.

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).

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.

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.

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.
