Answer 1

Use one of the _itoa() family of functions or StringCchPrintf(). The links go to the 'safe' versions of the functions, but the winapi also provides 'unsafe' and leagacy variants.

Answer 2

You can use itoa function, which is much simpler than sprintf, but may not be available in kernel.

If itoa is not available, you can recode it: itoa in GCC

Answer 3

You can't simply convert it. C just isn't so friendly.

You need to:
1. Get a large enough TCHAR array, where' you'd put the number. You can use a simple array on the stack (but it depends on what you want to do with it).
2. Convert the number to a printable representation in the buffer. _sntprintf can do this.
3. Use the address of this buffer.
