handling and processing accelerator messages
Mohammad Shahzad Saleem
how can i add the handler to the accelerator messages in the atl control? i
want to process the key combinations pressed on the keyboard, like Alt+M for
some thing. i have added an accelerator table in the resources with few
accelerator entries and loading it in the method "GetControlInfo". i dont
know how to add the handler to the acceleratr messages. please give me some
suggestion ...

table, you can use ::TranslateAccelerator API there to generate an
appropriate WM_COMMAND message (assuming your control is windowed).

is not getting called. I have check it into the msdn, i think
PreTranslateAccelerator is not the member of CComControl or even any other
class.
Please tell me the steps to achieve the keyboard accelerators get processed.
I dont know when & where to call the TranslateAccelerator API. and how to
handle the WM_COMMAND Message in ActiveX control.
I read about message pump while searching the web and consulting the msdn.
it is written there that messaeg pump should be placed in the WinMain. i
dont find any relationg of WinMain to the ActiveX Control.
Everybody talks about that the key combinations like Ctrl+O, ALT+M etc can
be processed using accelerator tabel in the ActiveX control. but when it
comes to explain they end up explaining how to handle Tab, Enter and Esc
keys. I am stuck at this point i wonder wehat the heck is this.
i am developing multi-lingual edit box and editor control.. in that control
i need to trap keys pressed on keyboard in combination for marking the text,
changing editing modes and switching between the languages during run time.
I dont believe that Ctrl+C, Ctrl+V & Ctrl+X keys have never been implemented
in windows standard edit boxes! then why cant i ...?
please give me usefull suggestions
i will be greatfull.

It's there in the ATL source code, and it does get called. Maybe yours
has an incorrect signature. It should be
BOOL PreTranslateAccelerator(LPMSG pMsg, HRESULT& hRet);
You return TRUE if you have processed the message and FALSE otherwise.
If you return TRUE, you should also set hRet to an appropriate COM error
code (most often S_OK). This code is eventually returned from
IOleInPlaceActiveObject::TranslateAccelerator

From PreTranslateAccelerator. It should be called if you do everything
correctly.

Just put COMMAND_ID_HANDLER macro into your message map.

The container runs the message pump for you. You don't need to provide
your own unless you spin worker threads.
