Formatting Numbers in Strings

I'm using sprintf to print numeric & string data into a buffer.
The code i've used is sprintf(szBuf,"Size : %d bytes",&fsize)

So far so good.

How can i set up the number to be formatted to show seperators ie
What i want to display : Size : 1,128,654 bytes
What i'm able to do with sprintf : Size : 1128654 bytes

I recall seeing something on MSDN that would take a file size in bytes, and then print it out, as in File->Properties.

I couldn't find it again though - will keep looking :)

Found it :)

Thanks you very much, just what i needed.

No problem.

BTW - this is the function that Explorer uses :)
