initcommoncontrolex question

I am making a status bar in my application and I was wondering which way was the correct way to initiate the common control function. Here are the two ways I'm using

Code:

---

INITCOMMONCONTROLSEX InitC;
InitC.dwSize=sizeof(INITCOMMONCONTROLSEX);
InitC.dwICC = ICC_BAR_CLASSES;

InitCommonControlsEx(&InitC);

---

or

Code:

---

InitCommonControlsEx(NULL);

---

Both ways work. Which way is the correct way? Thanks.

If the docs don't say that the parameter is optional or that NULL is an acceptable value, then the function will generally fail. The second method doesn't really work (it'll return FALSE) but your program still works because at the current time InitCommonControlsEx is called internally when the dll loads.

Use the first and you won't go wrong.
