I'm a Computer Science major at a small university that teaches C++. Recently I've started to do some research on my own, because I don't believe my university is teaching me everthing I need to know and I came across tchar. What and how do you use tchar? I tried searching but I couldn't fine much information and when I tried to use tchar in a program I got undefined variable and usee I did include the header file tchar.h. Thanks for your help.
TCHAR is a macro that translates to wchar_t when the program is compiled for UNICODE and char when not. Its defined in tchar.h. A wchar_t is a UNICODE wide character designed to hold characters of most languages, such as English, Spanish, Chines, Japanese, etc. Characers of many of those languages cannot be represented in an 8-bit char, so UNICODE designed wchar_t, which may be defined as unsigned short on some operating systems or unsigned long on others. Google for UNICODE and you should find a lot of information.
Thanks but how would I go about using tchar? I'm really not sure about macros because I've never done anything with macros.
You would still have to do some research (to find out how to use all the macros in tchar correctly) but macros in general work with the preprocessor directive #define MACRO_NAME value. You then can use the phrase MACRO_NAME through out your program. At compile-time the compiler substutes the text for the value.

Ok -- here's an example -- note the spelling and capatalization -- it is TCHAR, not tchar.
Code:TCHAR hello[] = _TEXT("Hello World");
Thanks. I saw that example earlier on the web and it still gives me undefined. I've even copied and pasted the example.Originally Posted by Ancient Dragon
you need to include tchar.h
Read man I did use the include tchar.h file. Sorry, but people who refuse to read a post just irritates me.
well then try posting your program. people who complain without posting any code irritate me too.
This works with VC++ 6.0, although TCHAR will be defined as char* unless _UNICODE is also defined before including tchar.h
Code:#include <tchar.h> int main(int argc, char* argv[]) { TCHAR hello[] = _TEXT("Hello World"); return 0; }

I didn't post code because there was no code besides the code I posted. I used include file and then declared a TCHAR. Of course I used a main and return 0 but I didn't think you needed to see thatwell then try posting your program. people who complain without posting any code irritate me too.

Updated. I copied and pasted your code and its a no go. I'm using the borland compiler for C++
>>I'm using the borland compiler for C++
well that pretty much sums up the problem -- throw that cr@p away. Check its tchar.h file and see if it needs some other macro defined, such as _UNICODE. The compiler's preprocessor may be ignoring tchar.h entirely.
What free complier would you suggest? I've never had any problems with the borland compiler. Is there a reason you think its crap, besides tchar?>>I'm using the borland compiler for C++

There is nothing wrong with BC++ Ancient Dragon is being a bit bias. I would say that you do not need to concern yourself with wchar_t unless you are planning for your programming to used in mulitple languages.
Woop?
You didn't answer my question (or statement) -- did you look at your copy of tchar.h to see why it doesn't recognize TCHAR macro?
I didn't look at my tchar.h file because I haven't had the chance, I'm sorry its been less than a day since you asked and I'm studying for files.
I'm interested in tchar because I want to get a job with Microsoft. I've been doing a lot of research and watched a Microsoft recruiting video and in their interview question they expected the person to know how to use tchar.
