c - Are child windows destroyed automatically if -1 is returned from WM_CREATE? -

- 

lresult callback wndproc(hwnd hwnd, uint msg, wparam wparam, lparam lparam) {     switch(msg)     {     case wm_create:         {             hwnd hstatic1, hstatic2;             hstatic1 = createwindowex(0, l"static", l"", ws_visible | ws_child, 4, 20, 40, 40, hwnd, 0, getmodulehandle(0), 0);             hstatic2 = createwindowex(0, l"static", l"", ws_visible | ws_child, 4, 80, 40, 40, hwnd, 0, getmodulehandle(0), 0);             return -1;         }         break;      default:         return defwindowproc(hwnd, msg, wparam, lparam);     }     return 0; }

are child windows created in wm_create destroyed automatically when -1 returned? hstatic1 , hstatic2 destroyed automatically when return -1 or need call destroywindow() on each 1 of them?

all child windows destroyed when window destroyed, , includes when window destroyed during creation returning -1 wm_create.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
