That's because you are wrapping 'number%d' in single quotes! Use double quotes "number %d". By the way this won't work out, try this!

const int SomeNumber = 100 + 200;
char buff[100] = { 0 };
sprintf( buff, "My number is: %d", SomeNumber );
MessageBox( buff );

There is a function called CString::Format, if you are interested! And if you are further interested you can have a look at this[^].

are you trying to do something like this?

char buff[100];
sprintf( buff, "number %d", number );
MessageBox( buff );

CString op;
op.Format("Number : %d",num);

// or

Good C tutorial needed. Hint: string literals must be enclosed by double quotes. :)

What in the world is this? :confused: The documentation plainly shows that MessageBox() expects four arguments.
