Re: Event handler continues executing after its dialog is deleted

" Do you know what conditions the modal loop stops on? Does it respond to
WM_CANCELMODE?"

Some of the event loops that I am using respond to WM_CANCELMODE. And that
is easy solution, cause I can send the message to exit the loop, through
code when the dialog is closed. In this case my event handlers like
OnBtnClick that are using the function that started the event loop, can
check
how the event loop was exited ( the function that starts the event loop
can
return status about success, cancel ..) and if it was Canceled it can
simply
return, and I will not have to reorganize access to member data , so
everything is ok :
void MyDlg::OnClose()
{
send WM_CANCELMODE here
DestroyWindow();
}
void MyDlg::OnBtnClick()
{
  if(GetGeometricObject == Cancel)
      return;
  acess to member data here
}

Problem :
I also have to use functions that starts event loop , but not respond to
WM_CANCELMODE. How should I do then ?

"Normally, you'd call set capture to prevent the mouse/keyboard going
anywhere else, and then exit the loop in certain circumstances, and in
general preventing reentrancy to UI options. Menu functions run a similar
loop."

I don't understand this :(
