Obtaining a list of all registered window classes?

Anyone know if there is a way to enumerate all available window classes that were registered with RegisterClass, RegisterClassEx, or GlobalAddAtom?

Code:

#include <iostream>
#include <set>
#include <algorithm>
#include <windows.h>

typedef std::set<std::string> MYSET;
const int BUFF_LEN = 255;

BOOL CALLBACK EnumWindowsProc(HWND hWnd,LPARAM lParam){

        MYSET* lpSet = reinterpret_cast<MYSET*>(lParam);
        static char szClass[BUFF_LEN];
       
        if(GetClassName(hWnd,szClass,BUFF_LEN))
                lpSet->insert(szClass);
       
        return TRUE;
}


int main()
{
        MYSET setClasses;
       
        EnumWindows(EnumWindowsProc,
                reinterpret_cast<LPARAM>(&setClasses));
       
        std::copy(setClasses.begin(),setClasses.end(),
                std::ostream_iterator<std::string>(std::cout,"\n"));

}

:D I take it then there is. :D

Thank you Fordy, I owe you a beer for that one. :)

this is kinda off-topic, but if I declare a window class in one module, can I use it in another one?
