whether the function AddWindow in the last example has executed yet. If
your main window is not an alias, AddWindow hasn’t executed. If your main
window is an alias, AddWindow has executed:
void
TMyApplication::CheckAddExecute()
{
if(GetMainWindow()->IsFlagSet(wfAlias))
// MainWindow is an alias; AddWindow has executed
else
// MainWindow is not an alias; AddWindow has not executed
}
