Hi Whitesky,

I want to use skin on a dialog.. For that i designed the image using photoshop and saved it as a .bmp image. But how to use it as a skin is my problem. Its not at all getting displayed.. But if i try with 16-bit color bitmap it is getting displayed.. do i have to use some other methods to display it?

With Regards,
Sangeetha.

Hi Whitesky,

Thank u very much.. it works.. the wrong thing i was doing is i didnt use the import option while creating a new bitmap resource in the resource editor.

Thank you,

Hi Peter,

i dont like cross-posting nor do i like to
ask questions especially on wrong boards, but
as a developer i know that most of use have
a huge knowledge on this area. This is a very
strange and big problem for me, since i didnt
find the problem by my own and it really is hard
to find. I am a experienced developer and
administrator, but this is a very hard thing!

Anyway, thanks,....

Best regards

True -- there's people here who know a lot.

But cross-posting a link to another site.....?

Why not post the question directly here? Short and direct. I have to say, I started reading the other post, got half way, and stopped.

Edit your question, make it appropriate for this group, and post it directly here.

So do the right thing, and post the question in the Hardware forum. Those same folks that have "huge knowledge" also frequent the Hardware forum. Wink | ;)

Thanks in advance

When your window is created, you can add it to the WTS session notificatio by passing in the window handle (which you now know), and when it is destroyed, remove it from the session notification list.

Create a message handler for the session notification message. Process the messages of interest to your program from this handler.

Virtual function default behavior [modified]

bob1697211-Aug-07 12:01

bob16972

11-Aug-07 12:01

I know Scott Meyers says something about "don't provide default behavior in a virtual method at the base class level".

However, I left my book at work and can't remember "why".

I seem to need default behavior in my base class for a specific virtual function but I'd hate to do it without going over the pro's, cons, tradeoffs, gotha's...

Does anyone remember the reasons why a base class virtual function should not have a default implementation? Or am I remembering what he states incorrectly?

-- modified at 10:46 Thursday 16th August, 2007

UPDATE:
Now that I've had a chance to look at the book, I'm guessing I remembered incorrectly as I can't find anything close to resembling this topic in Meyer's books so forget the question ever existed as my brain is obviously overloaded and functioning improperly.

Re: Virtual function default behavior

Maxwell Chen13-Aug-07 0:08

Virtual functions are for runtime cadidates (late binding or dynamic binding) which are valid via pointer access. To provide the default behavior of the base (as you stated), it would be compile-time binding (static binding), and it gets far away from what virtual was intended for.

Blake Miller13-Aug-07 8:33

I typially provide a reasonable defualt implementation unless it is declared as pure virtual.
My reaspning is I want something known to happen. If it is overridden in a derived class, they must want 'something else' to happen.

How do you figure?

If a base class A has a virtual function Foo() and a derived class B implements it and I have an array of A* that point to objects that have runtime types of A or B, it will decide which version of Foo() gets called at runtime.

How is that getting away from the original intention of virtual?

Size of a track bar?

PJ Arends11-Aug-07 10:51

PJ Arends

11-Aug-07 10:51

Hey all,

I am trying to create a dialog bar that contains a single track bar control. My problem comes with determining the proper size of the dialog bar so that it will show the entire track bar without having a bunch of extra space. Is there a way to determine the area needed to display the track bar, especially if I were to make the tick marks user selectable?

The track bar control has the TBM_GETCHANNELRECT and TBM_GETTHUMBRECT messages to get the area of the channel and thumb components of the control, but it does not have a way, that I know of, of getting the area needed for the entire control. I could take the channel rect and OR it with the thumb rect to get close, but I was wondering if there was a better way.

You may be right
I may be crazy
