CString Format method

[developer155]

Can someone please explain or point me to comprehensive source of info on CString::Format. I looked at docs at MSDN, they dont really explain how it works. Like what would this do?
SomeCString.Format ( "%12.0f", Milliseconds );

and

AnotherCStringFormat( "%.1u", "Location" );

what would be the out put and how does it work?

thanks!!!

The CString::Format method expects a string in a format identical to what you would give printf or a similar C function. Try doing a Google search for it instead and you should find all you need to know.

How about yout write a small app that does that very thing. Set a breakpoint and step into the code to see what is happening.

>what would be the out put
Now, how can you figure that one out?

Yes, MSDN has a lot of wisdom about CString (printf like) format specifications. Or take any C book and read printf() samples.
We can say at once that 2nd Format do nothing (useful): it tries to print string literal pointer ("Location") as unsigned int (%u format spec) while precision spec (.1) is not applicable to u specifier and is ignored...
