Hello, I want to write a small vocabulary trainer (EN <=> Spanish). Now I need to know, if two strings are similar. When the trainer ask you, what the meaning of "veinte" is, and the user writes "tewnty" instead of "twenty" the application should only remark that there is a small mistake in the input. When he writes a total different word (e.g. wine) then the trainer should say, that there is a mistake in the input. Know anyone of you a good class, which compares two strings on similarities? The class should detect if there is a letter missing or a letter too much (or 2 letters are flipped). Till now I just found classes, which compares complete texts and which say that a line in text A is different to a line in text B. Bye
