mfc - CButton gets send WM_SETSTYLE to BS_DEFPUSHBUTTON Message when clicked -

-

i have several cbutton objects. when click them, send wm_setstyle message changing style bs_pushbutton bs_defpushbutton. change permanent , not go away when push button. 

cbutton* button = new cbutton; button->create(l"button", ws_child | ws_visible , crect( 10,10,100,100), this, idc_button);

what cause behaviour?

for testing purposes created new project scratch. there buttons don't changed. not able figure out, differently.

in dialog or window child windows states handled wm_nextdlgctl respective cwnd::gotodlgctrl , cwnd::nextdlgctrl/prevdlgctrl

you should never use setfocus in dialog when buttons involved.
