file comparision

[krallabandi]

Hi,

I have a requirement to compare 2 ASCII text files and show the results
in an aspx form.

The comparision algorithnm, out put should be similar to VSS
(differences between 2 files).
I really appreciate if you can tell me the best way of doing this and
what web controls suits this requirement.

Thanks,

You can look at diff's implementation. Also check winmerge
(http://winmerge.sourceforge.net/) - they have a very good interface. I
am unsure about any COM components which can do this though.

We at Grig Software (http://www.grigsoft.com/) are testing now 2
components -
1. dll with comparison engine. You can create UI yourself then with
comparison results from it.
2. ActiveX with full UI duplicating our Compare It! tool.

If you are interested, please contact me personaly at
support---grigsoft.com.

you could download the sources for diff, put them in a project, and simply
change the name of the main function to MyDiff or something else.
then you supply the filenames to MyDiff, just as you would to the command
line version of diff.

since diff is a simple command line tool, it probably doesn't need linux
specific headers or libraries.

i have done this before for some command line apps, and it is generally a
very fast way to incorporate code into your application.

the only issue might be diff's license. that might be incompatible with the
license of your application.

kind regards,
Bruno.
