Very easy I think....

Hi experts...
Some time I see some code that I don't understand...

I love program on windows directly in MSVC++ without MFC.

Well... What does it mean... It is in the code that defines the class window to be registered.
Keep in mind that wcex is a WNDCLASSEX type variable

wcex.lpfnWndProc =(WNDPROC)WndProc;
WndProc is the name of the function that process the msgs.

wcex.hbrBackground      = (HBRUSH)(COLOR_WINDOW+1)
wcex.lpszMenuName = (LPCSTR)IDC_MENU;

IDC_MENU is a menu resourse ID.

Can any one explain to me what is the meaning of those "(SomeThing)"
I see things like that everywhere but I don't know how to use it.

I know use the parenthesys in theese situation if (), for (), function (){}But I'm not sure how do they work in thinks like this

something = (OtherThing)AnotherThing.

And where else can I use this kind of code?

Can any C++ expert explain to me?.
Thanks.
