2 questions

I figured there would be too, and I did look in the MSDN, but didn't find anything. Maybe I didn't look hard enough.

Have a look at this

Code:

---

isdigit, iswdigit

isdigit returns a non-zero value if c is a decimal digit (0 – 9). iswdigit returns a non-zero value if c is a wide character corresponding to a decimal-digit character. Each of these routines returns 0 if c does not satisfy the test condition.

Here are some else if you are ineterested

Code:

---

isalnum

Alphanumeric (A – Z, a – z, or 0 – 9)

isalpha

Alphabetic (A – Z or a – z)

__isascii

ASCII character (0x00 – 0x7F)

iscntrl

Control character (0x00 – 0x1F or 0x7F)

__iscsym

Letter, underscore, or digit

__iscsymf

Letter or underscore

isdigit

Decimal digit (0 – 9)

isgraph

Printable character except space ( )

islower

Lowercase letter (a – z)

isprint

Printable character including space (0x20 – 0x7E)

ispunct

Punctuation character

isspace

White-space character (0x09 – 0x0D or 0x20)

isupper

Uppercase letter (A – Z)

isxdigit

Hexadecimal digit (A – F, a – f, or 0 – 9)

Well I get bored easily looking at lists of function names, so I didn't look that hard :rolleyes:

It is really funny nobody remembered the isdigit function. I searched the isalpha function to get to the isdigit.

isn't there a IsCharAlphaNumeric Api Function?

Yep there is :D

For some reason I tend to do everything with the API rather than C libraries (altough this eliminates the possibility of cross-platform code, it saves in FileSize)

Look for TINYCRT on MSDN if you want to keep your file sizes down and you use API most of the time.

Thanks mike, will take a look at it :D
