Post conditions are required by design by contract approach, or am I wrong?

Yes, no, both. assignment operator, and other other operators, have implicit contracts. Read Meyers. ( I am getting a little tired of saying the "read Meyers" part you know )

It's a twist on a quote from a movie Adventures of Buckaroo Banzai Across the 8th Dimension[^] where a character said "Laugh while you can monkey boy".

OK, I will do. However,you know, design by contract is only one of the possible approaches.

I really appreciate you elaborated, thank you.

Yes I know, and not the most popular approach. The most popular approach is probably the Disastrous Bowl of Worms approach. That's the one where you ignore all the advice from people like Kent Beck, Martin Fowler, Scott Meyers and others.

No. It means that rollback is an inappropriate post condition for an assignment operator since it is not part of the implied contract of the assignment operator.

Hi led mike,
What is your contract? My contract is, exception could be thrown, but all status of object should be consistent. Your contract is, if exception is thrown, status of object is unknown?

My contract is: READ MEYERS!

(Hopefully this is the right forum - This is all done in VC++.NET)
Sprinkled Throughout the various project I have are some where, if the design mode window is part of startup, it takes a rather long time for the project to be loaded. Similarly, if already opened, opening the design-mode window take a rather long time. I believe I know why it's happening, but I don't know how to stop it - and it can be very annoying.
Why I know:
1) Projects with database's attached (::SqlClient) are the worst offender - but not all of them.
2) A digital clock drop-in control I made, when put into a project, was actually ticking merrily away in the design mode window
I conclude that the horrid delay may be establishing (and timing out) of dBase connections.
Does anyone know how to disable this 'live' state of a project that, in my philosophy at least, should not be running?
For now, it's a catch-22: I can re-arrange the code and the items aren't intialized at this point - but that also means they're not on the designer window and that sort of defeats the whole purpose - which is having an open designer window.
Thanks, in advance,
Balboos

Depends Visual C++ from 2003 on up all include .NET platform extensions for using the .NET platform in your project. If you are doing that the this is not the right forum. If you are doing native C++ then this is the correct forum. For .NET development using C++ you want the Managed C++/CLI forum.
Balboos wrote: A digital clock drop-in control
Drop-in control? Never heard that term. TIP: Don't make up your own terminology there is already far to much and people won't understand what you are saying. So do you mean you developed a custom control that includes a Visual Studio Designer interface?
Balboos wrote: Does anyone know how to disable this 'live' state of a project that, in my philosophy at least, should not be running?
I can't be sure what that means but if you are talking about your custom control then yes. The designer interfaces include the ability to know during initialization if it is a designer instance. You can use that information to avoid doing any processing that you don't want the control to do in designer mode.

Yep - will repost in correct forum.
led mike wrote: do you mean you developed a custom control that includes a Visual Studio Designer interface
I'll try to be a bit less sloppy in my terminology, and, the answer is yes: it's a custom control. I use the term because the designer is drop-and-drag, and so I made something to drop.
Thanks,

As far as questions go, you can ask as many as you like.

Hi all,
I am kin in learning Visual C++ / MFC (Microsoft Foundation Class), but i was quite trouble as i do not know where to start. I've been reading up on Basic C++ like usage of Functions, Arrays and theories. I also downloaded simple programs to explore and see the differences and changes that will be made if i change the contents within the program.
I will like learn again, from the basics as i fail to do so during my previous tertiary education in Diploma in Electronics. I wish to learn now so as to prepare myself to do effective projects in my next upcoming tertiary education. Please kindly assist
Thank you.

Hi there,
There is more than to learn just C++ for MFC. If you were to listen, people here can recommend you very good books with which you could start learning MFC/Visual C++.
I'll say buy the one written by Jeff Prosise (Programming Windows with MFC). Good luck with your learning.
