Flat ScrollBar ActiveX

hi

The flat scroll bar has 2 button like ends
with arrows and a slider button like somewhere
in the middle. Ok i need to know if there's a way
to find out the width of the "arrow" end buttons ?

I know that im actualy looking at a bitmap that
looks like buttons but im asking anyways =/

thanks

Firstly, what you call a slider button is normally referred to as the "thumb".

Secondly, all scroll bars have an ancestor class, CWnd. You only need interrogate this
MFC class to establish the width/height and border properties of a scrollbar (or
indeed the base properties of any window derived from CWnd). Indeed, the scroll
buttons and the thumb of a scrollbar are nothing more than CButton classes, which
themselves are descendents of CWnd. Therefore it's not too difficult to interrogate
these base classes to establish the width and height information you seek.

...and you're asking a Microsoft Visual C programming group because...?

With the scrollbar on view, take a screenshot using the [Prt Scn] key, then paste the
result into MS Paint (or any suitable image editor), zoom in to the bitmap region in
question and count the pixels for yourself. Note that the width is dependent upon your
current display appearance settings (e.g., font sizes). You cannot guarantee that
everyone will use the same appearance settings as you.

Programmers don't have to second-guess your individual appearance settings because
every window (a scrollbar is just a type of window, as are the buttons and thumb of
the scrollbar) knows its own width and height at runtime.

...when did "plain old Windows" became synonymous with MVC? Windows is an OS, not an
IDE.

erm ... it didnt, but Windows being os has nothing to do wth that.
You stated that its MVC newsgroup, so its logical to assume that people
asking questions here use MVC (which doesnt mean they necessarily use
MFC)... isn't it ?

you were talking about a CWnd class. Thats MFC.
I mentioned "ol windows", because a "Window' per say
is not a OS even if i use more then one right ? ie:
CreateWindow(...) .. What if there was a Message to get
info on the button size of a scrollbar , then id be sending
a "windows message". Hence Good Old Windows etc...

Correct.

Wrong. "Windows" is an OS, period. All the windows created in Windows have lower-case
ws. There is no such thing as a singular "Window", only a window. The plural is
windows, of course. Capitalisation is as important in English as it is vital in C++.

> ie:

The CreateWindow() function simply creates a window. It does not literally create a
Window.

No. You'd be sending a Windows message. Not that you need to send messages.

> Hence Good Old Windows etc...

Try "good old Windows API" and it might make sense. Are you creating a Win32 project
perhaps? No matter. Suggest you look up GetWindowHandle(), GetWindowRect() and
GetClientRect() -- the exact same underlying functions used by MFC and indeed .NET,
the only differences being syntax.

But it has everything to do with my statement. Whether he uses MFC or not is beside
the point. The OPs statement, as written, makes it sound like he doesn't use MVC at
all -- "just plain old Windows". Taken literally, I' have to assume he writes all his
code in Notepad...

Logical, but not always correct.
