another question..
if i want to execute an action when the ok button is cliked how can i do it?
whe i add a button(widget) i know how to handle it. please see my code.
// Call the base class Update function so that default behavior will still occur (OK and Cancel buttons, etc.).
CDialogObserver::Update(theChange, theSubject, protocol, changedBy);
do
InterfacePtr<IControlView> controlView(theSubject, UseDefaultIID());
ASSERT(controlView);
if(!controlView) {
break;
// Get the button ID from the view.
WidgetID theSelectedWidget = controlView->GetWidgetID();
if (theChange == kTrueStateMessage)
//if (theSelectedWidget == kEXTCODGoButtonWidgetID
switch(theSelectedWidget.Get())
         case kEXTCODGoButtonWidgetID:
  this->ViewOutput();
  break;
         case kEXTCODFindButtonWidgetID:
  this->SaveLog();
  break;
// TODO: process this
} while (kFalse);
I do two actions "SaveLog" & "ViewOutput()" using two buttons. But i dont know how to execute an action when the ok button is clicked...
