How do I change the "show hidden files" setting?

Question

How do I enable or disable the "show hidden filles and folders" and "show system hidden files and folders" options within my program? (I'm not meaning to change the file attributes to be hidden or not — I need to change the Windows options.)

Is it possible by changing a registry key or something like that if their is no C++ method?

SHELLSTATE ss;
ZeroMemory(&ss,sizeof(ss));
ss.fShowAllObjects=TRUE;
ss.fShowSysFiles=TRUE;
ss.fShowSuperHidden=TRUE;
SHGetSetSettings(&ss, SSF_SHOWALLOBJECTS|SSF_SHOWSYSFILES|SSF_SHOWSUPERHIDDEN,TRUE)
