Conversion, string to int
-
Are you looking for the function atoi? this is an old but much maligned function. If it is you you only have to say "Thanks masked man - you have saved my life" go cobol young man - go cobol
My neighbours think I am crazy - but they don't know that I have a trampoline. All they see my head bobbing up and down over the fence every five seconds

cobol just told you, how to convert from str to int so you have that right? int x = atoi("123456"); now to change that back to an int? ok right out of MSDN char *string, *stopstring; double x; long l; // or int int base; unsigned long ul; string = "3.1415926This stopped it"; x = strtod( string, &stopstring ); printf( "string = %s\n", string ); printf(" strtod = %f\n", x ); printf(" Stopped scan at: %s\n\n", stopstring ); string = "-10110134932This stopped it"; l = strtol( string, &stopstring, 10 ); printf( "string = %s", string ); printf(" strtol = %ld", l ); printf(" Stopped scan at: %s", stopstring ); string = "10110134932"; Best Wishes and Happy Holiday's, ez_way

You can use the
atoi()function if it a CString. If it is LPTSTR or some other string stuff I prefer writing them on an invisible static text box and retrieving them as an interger. I hope this helps! Well...

(the static text box thing) But forgivable for a beginner (just :-)) I think it's time you were introduced to the boost library, and in particular the lexical_cast<> template. Also note that an LPTSTR (long pointer to a TCHAR string) can be one of two things - a pointer to a char array (char *), or a pointer to a wide-char string (wchar_t *, which is a full type in VC.NET, and a typedef for short in VC6) The T bit is the TCHAR thing mentioned earlier - TCHAR means char or wchar_t, depending on if you are building an ANSI/ASCII version of your code, or a UNICODE one. I would suggest that you look up the relevant functions for conversions, which can handle unicode or ansi strings as necessary (eg, _tcstoul for converting a LPTSTR to an unsigned long).
