Absolutely not. The function asks for a window handle. That's what you
need to give it. None of the numbers from zero to four refers to a valid
window, but only zero has special meaning ("the dialog box should have
no parent window"). The others are simply invalid window handles.
If the function is going to display any dialog box, it will do so
_before_ the function returns. Therefore, you'll only have one call
active at a time, unless you're invoking the function from multiple
threads simultaneously.
