I have a mainframe with a drop down menu. User has option to click on these
items from drop down menu to open other dialogs. When the user hit the save
button after he has done with the configuration, I want only data has been
changed are saved (only those dialogs which are opened and modified will
I can do that with those dialogs which have string member:
These string members are expected input from user. If user don't enter anything,
no new data, no save. (thanks to .IsEmpty())
But with those dialogs which don't have string members, only integer members,
how can I handle this?
I can not some similar thing like:
if(m_int < 0) return TRUE because this member always display a number from
the system. This m_int always has some value in it, and its dialog will always
be saved if the user hit the save button. That is not what I want. Is there
anything similar to IsEmpty() to check the integer???
Any help will be graetly appreciated!
