mfc - How to disallow tab key to switch focus between edit control and button within dialog box? -

i have dialog box having buttons , edit box.
when edit control have focus if press tab key moves , focus button.
wanted tab key work in such way not switch focus instead should work tab input inside edit control i.e. input edit box keys.

the solution simple, , consists of handling wm_getdlgcode message. allows control implementation fine-tune keyboard handling (among other things).

in mfc means:

• derive custom control class cedit.
• add on_wm_getdlgcode message handler macro message map.
• implement ongetdlgcode member function, adds dlgc_wanttab flag return value.
• subclass dialog's control, e.g. using ddx_control function.

header file:

class myedit : public cedit { protected:     declare_message_map() public:     afx_msg uint ongetdlgcode(); }; 

implementation file:

begin_message_map(myedit, cedit)     on_wm_getdlgcode() end_message_map  uint myedit::ongetdlgcode() {     uint value{ cedit::ongetdlgcore() };     value |= dlgc_wanttab;     return value; }
