(as the input is restricted to certain characters). How can I display my new 

keyboard instead of the existing ones when the 'ABC' or '123' corners of the

What you need to do is catch the event that occurs when the 'ABC' or '123' is pressed, 
run a function to display the keyboard, and return true to the system so it doesn't 
draw it's own keyboard.

Here is the code you need to put in your event loop:

        if (KeyBoardCatch(&event))
                continue;

KeyBoardCatch() is a custom function.  It should be something like this

Boolean KeyBoardCatch(EventType *event)
{Boolean handled=false;
//if the event is not a keydown event, we don't want to mess with it.
if(event->eType!=keyDownEvent)
return handled;
//Check to see if the 123 or abc was pressed
switch(event->data.keyDown.chr)
{
case vchrKeyboardNumeric:
//123 was pressed
MyCustomNumericKeyboardDrawingFunction();
break;
case vchrKeyboardAlpha:
//abc was pressed
MyCustomKeyboardDrawingFunction();
//make sure to return true
handled=true;
break;  
default:
break;
}
return handled;
}

Now you need to put some code in the event loop:

//sample event loop
do {
        EvtGetEvent(&event, evtWaitForever);
//right here is where you need to insert the call to KeyBoardCatch
        if (KeyBoardCatch(&event))
                continue;       
//rest of event loop
        if (! SysHandleEvent(&event))
            if (! MenuHandleEvent(0, &event, &error))
                if (! ApplicationHandleEvent(&event))
                    FrmDispatchEvent(&event);
    } while (event.eType != appStopEvent);


Hope this helps.
