can I use following code?
//...
TMyForm *form = new TMyForm(NULL);
try {
form->Show(); // I set the Action parameter of the
OnClose event to caFree. so normally it should free the memory itsselfe
}
catch(...){ // for the case that any exception
has been thrown.
delete form;
}
//...
I don't want to use ShowModal, since my Form represents a progresswindow
that has to be updated by another function.
