But if I move with a window(which is currently open/active) the text will get bold. Even if I click on the desktop the text on the desktop will get bold.

But if I hit F5 and the desktop is active - the text is normal.


Can you give me a hind, what I am doing wrong?

can you show me how to get the address of +, so I can use it as a functor in an STL algorithm?

y does we use it as sizeof(type) as a function...

The sizeof operator yields the number of bytes in the object representation of its operand. The operand is either an expression, which is not evaluated, or a parenthesized typeid.

#include <stdio.h>

int main(int argc, char** argv)
{
   printf("%d\n", (int)(sizeof 3+4)); // Prints 8
   printf("%d\n", (int)(sizeof (3+4))); // Prints 4
}
