CreateProcess() c++ file not found

Question

I\'m trying to use CreateProcess to start a child process, however I keep getting error 2, which, according to the documentation is file not found.

Answer 1

With QT the MSDN function TEXT() it doesn't work: QTCreator's compiler return:

'Lvar' undeclared (first use in this function)

where var is input of Text(), because of QT whose enable UNICODE and because of that:

    #ifdef UNICODE
/*
 * NOTE: This tests UNICODE, which is different from the _UNICODE define
 *       used to differentiate standard C runtime calls.
 */
typedef WCHAR TCHAR;
typedef WCHAR _TCHAR;
/*
 * __TEXT is a private macro whose specific use is to force the expansion of a
 * macro passed as an argument to the macro TEXT.  DO NOT use this
 * macro within your programs.  It's name and function could change without
 * notice.
 */
#define __TEXT(q) L##q
#else
typedef CHAR TCHAR;
typedef CHAR _TCHAR;
#define __TEXT(q) q
#endif

#endif

in particular this passage:

#define __TEXT(q) L##q

in winnt.h included by windows.h
So, to solve this problem, we have to add this:

DEFINES -= UNICODE

in the .pro file of the QTCreator's project and it will work.
