c++ - Filling a list with Window objects using EnumWindows -

i'm trying fill list 'window" objects of active windows can't figure out way save window information in windowlist. windowlist passed callback function through lparam parameter.

here current code:

std::list <window> windowlist; //in center.h   //in center.cpp:  void center :: detectwindows() {     enumwindows(detectwindowsproc, (lparam)&windowlist); }  bool callback detectwindowsproc(hwnd hwnd, lparam inputlist) {     if (iswindow(hwnd) && iswindowenabled(hwnd) && iswindowvisible(hwnd))     {         tchar tchartitle[100];         getwindowtext(hwnd, tchartitle, 100);          std::string title = converttchartostr(tchartitle);          window * windowptr;         windowptr = (window*)inputlist;          window newwindow((int)hwnd, title, true);         *windowptr = newwindow;          std::cout << (int)hwnd << "  -  " << title << std::endl;     }     return true; } 

when try print out every element in windowlist through loop, error message pops up, saying "debug assertion failed! expression: list iterators incompatible"

this loop:

void center::printwindowlist() {     (std::list<window>::iterator = windowlist.begin(); != windowlist.end(); ++it)         std::cout << ' ' << it->gettitle(); } 

hope can help

in callback function you're treating inputlist parameter window* instead of list<window>*. try this:

bool callback detectwindowsproc(hwnd hwnd, lparam inputlist) {     if (iswindow(hwnd) && iswindowenabled(hwnd) && iswindowvisible(hwnd))     {         tchar tchartitle[100];         getwindowtext(hwnd, tchartitle, 100);          std::string title = converttchartostr(tchartitle);          auto windowptr = reinterpret_cast<std::list<window>*>(inputlist);         windowptr->push_back(window((int)hwnd, title, true));          std::cout << (int)hwnd << "  -  " << title << std::endl;     }     return true; }
