compare two string and get the difference

[jyoti]

Hi there,
I am trying to compare two strings and get the differenc
in vbscript.

Example: Str1="This is a test text"
Str2="This is a fine test text but a little long"
I like to compare str1 with str2 and get the difference.
Above example the difference will be "fine" and "but a
little long"
How do I do that? A sample code would be apprciable.

Thanks for your time

Jyoti
