How to conversion from upper case string to lower case in MFC.

Hi.. Use _tcsicmp
Hi.. I am Mnaju.I have Completed my B.E Computers Science.Lokking for a job.I am interested in VC++ manju
why bothering cast back to TCHAR*, uppercase, then cast back to CString, when the CString class already provides a method to do it ? moreover, _tcsicmp() doesn't perform a "toUpper" or a "toLower". it just compare 2 strings without taking care of the case.

_tcsicmpdoes a lexicographic comparison between strings. It cannot convert between upper and lower cases. In short, it does some kind of comparison and the OP's requirement is to do some kind of conversion. :)Nobody can give you wiser advice than yourself. - Cicero .·´¯`·->Rajesh<-·´¯`·.

CString has the MakeUpper() and MakeLower() functions, but you need to understand that upper case and lower case exists only in English (and may be in those languages that uses English script). It is not a very good idea to make this call on a language like Hindi. I believe you understand it.

For other languages, could be it done just adding or decreasing the "letter value" by 34 (or whatever value that gives "A" - "a")? Missunderstood of previous answer

I am talking about those languages which has no UPPER or lower cases. It just would not mean anything do a conversion in that case. I also mentioned "Hindi", in my previous post, as an example.

Exactly, Some language do not have upper and lower case.They have only one type as you said in hindi. I agree. But i need to convert Russian language. They have upper and lower case and MakeLower / _tcslwr in not working on russian. Do you have any other solution.

Yes, I tested with CString::MakeLower() and it isn't working! Fortunately for you, it shouldn't be a daunting task to write your own mapping routine, because there are not too many characters in Russian language. Imagine writing a conversion routine for something like Chinese, if it had UPPER/lower cases! :)
