i have displayed the contents of the files in the richeditcontrols.I dont know how to compare the files and highlight the differences in them.The codes which i got by surfing the net just tell whether the files are equal or not.They just return an int or bool value.Here is the place i got struck.

I think it's rather a complex task. I don't think you will get the "code" here right away. You may have to look at the XDiff[^] project. Perhaps that would help you.

My condolences. I had to do the exactly same thing some 5 years ago, and ended up with a post "I hate MFC" in the Lounge 
Anyway, to find the differences between files, use Longest Common Subseqence Algorithm[^] - that would be the easy part.
Now, for displaying it in the richedit controls - good luck with that

For example, if we create some object using new() and call delete(), the object will be deleted.
I want to avoid the use of the object before new() and after delete().
Can we check like if(object != NULL) or else?
BTW:
Sorry for delay I posted just before leaving office, now seeing from my room.

Suman

Yes, just set the pointer to NULL in your constructor and once you delete the object, just set it to NULL again.
|
|
|
|
|
So, I can check the object is not NULL before accessing it.
Thanks & Regards,
Suman

Onlyl if you are working with pointers because if you are working with objects directly, they are always "valid" (except if you did something really wrong, but anyway, there's no way to test it).

Hi Cedric, you are right..
Thanks for the great help!!

The whole essence of an object is that it knows about itself. Add an IsValid() method to the class. When that method is invoked, the object can check the validity of each of its members.

IsValid () is defined in which class of C++?
Thanks & Regards,

Did you miss the "Add an IsValid() method to the class" part?
