I want ask about TCHAR.h routine is undefined

Question

0.00/5 (No votes)

See more:

#define _WIN32_WINNT 0x0500 //for define Character Sets ID

#include "windows.h"
#include "string.h"
#include "stdio.h"
#include "locale.h"
#include "tchar.h"

//set windows code page 1252 Latin1 for TextOutA
_tsetlocale (LC_ALL, _TEXT ("german_germany.1252")) ;

When I compile , I got an Error from cl.exe (VC++ 6.0 / windowsXP sp2)

it says _tsetlocale is undefined.

I also tried other all the TCHAR.h routine (_tcsclen and so on)

but it still gives me the same error.

I wish someone could tell me Where is wrong ?

I do not see what is different in your solution to what you have coded in your original question. What has changed?

When I try your code (VC++ 6, WinXP sp3), it compiles just fine. What is the exact wording of the error?

error LNK2001: unresolved external symbol _setlocale would indicate you didn't link a C run time library[^].

error C2065: '_tsetlocale' : undeclared identifier would imply the #define hasn't been read. One possibility I could think of that would cause this is that the wrong TChar.h has been read. You use a quoted include rather than an angle-bracket include, which means it first scans your project directory before searching in the compiler's include path.
You could try hardcoding the path in the #include to eliminate this possibility;

#include "C:/Program Files/Microsoft Visual Studio/VC98/Include/TChar.h"

I'm also confused about what was changed, and the OP's explanation about why it now compiles. Probably another of those mysteries of the universe.

I think problem is not include path of head-file.

My VC++6.0 is installed at E:

[Tools] - [Options] - [Directories] - [Show directories for] -> (include files)

E:\Microsoft Visual Studio\VC98\INCLUDE (where the Tchar.h is)

I never changed this setting and path of VC6 since I installed VC6.0

whatever quoted ("tchar.h") or angle-bracket () I use.

my source works very well now, which I writed in my question.

and sorry for my fool!

I cannt get that error-word back anymore. because I really cannt know what mistken I did, and I cannt remember what somethings I changed later.

but one thing I still remember, when I tested it first time,
I pasted only Function-name '_tsetlocale' in source without () and parameters and ';' .
and selected it , right-click to choose "Go To Definition of _tsetlocale".

it said: symbol '_tsetlocale' is undefined (I sure all headfiles was included at top.)

!now it works. (I just cannt remember what somethings I changed)

now I tried again, I did same as I did first time.
paste only a function-name '_tsetlocale' in source without parameters and () and ';'.
and selected it , right-click to choose "Go To Definition of _tsetlocale".

It could Go to where it is defined in TCHAR.H now

it is really miraculous.

There does not appear to be a definition for _tsetlocale, see here[^] for the available options.

I really found _tsetlocale is defined in my TCHAR.h
/ I opened tchar.h with notepad.exe , Ctrl+F to find "_tsetlocale"

#define _tsetlocale _wsetlocale /for WCHAR
#define _tsetlocale setlocale /for CHAR

/ and I am sure my VC++6.0 include Directory path is right , because other head-files works

I dont understand why I got this Error

and all other TCHAR string routine (_tcsclen, _tcscpy, _tcscat) gets undefined-error too,
but they are defined in TCHAR.h

I fixed this error,

because I only write "_tsetlocale" in source.
and selected it ,
right-click to choose "Go To Definition of _tsetlocale"
and I got this error "undefined" from VC++6.0

I shouled write full function like this
"_tsetlocale (LC_ALL, _TEXT ("german_germany.1252")) ;"
