AFAIK the window (and every control is a window by itself) draws itself until the style is owner-drawn.
If you invalidate the parent window, this will draw itself and then force a redraw of EVERY of its child windows.
(To minimize this effect there is a function InvalidateRegion)
But my knowledge is from old WinAPI32 - may be something changed since then ...

i know every control is a window, but that's why i was asking who really draws the button "highlighting"? ...it would depend on how the framework implemented the highlighting, which i'm not really sure about... but if he says that dragging an explorer window over it does the trick, that has the same effect as invalidating the parent...

Are CDialog::SetDefID() or CDialog::GotoDlgCtrl() of any help?

Finally i got this working.
What i did was, do a SetFocus(ParentWindow) and then do a SetFocus(ChildWindow) on this order and it worked just fine.

Seems that is what I replied to another question - is it that this button is the only editable control on the form ?

Correct me if I'm wrong, but Visual C++ seems to have gotten properties right (this native Visual C++, non-standard attribute)...
__declspec( property( get=get_func_name, put=put_func_name ) ) declarator
I'm embarassed to say that they've had this for a long time and I'm only now messing with it (yes, I realize there are articles that talk about it here but I had never truly wanted to use this until just recently), but their approach to properties for native Visual C++ development allows the property to be used like a member (assuming proper implementation of the accessor and mutator of course) whereas the C# implementation has the restriction
"A property or indexer may not be passed as an out or ref variable".
So far it seems to work intuitively (and can do things C# properties can't  ), but...
Does anyone know of any serious negative aspects to using it besides that it's not standard? Am I missing some caveat?

Hi All
I am loading multiple object On OpenGL.When i load Only one object ,the object movement is
very smooth.After the increase the number object on screen at that time the movement is going slow.
Please suggest the way how to increase the speed when multiple object on screen.
Thanks

Are you loading your objects (or textures, or anything) from a file ? If yes, are you loading the file once or for every frame ? If you are loading the files for every frame, you should load them once at the beginning of your program. File I/O is very slow.
It's the only thing I can think that could slow down performance and that has a quick fix. If you already do that, then you will have to look for yourself how you can increase the performances of your program. Your question is so vague that there's no way to give you a correct answer.

sir what do i do so u can see the bitmap?
sir a small brief of my program is as follows.
my program is in win32,
i had used BMP image on the Dialog,
the BMP image cover the entire dialog.
BMP image is in blue color.
And added a button on the dialog.
without using manifest the button is ok, but after enabling xp visual style a strange border is created around the button. As the Dialog has BMP image loaded, it creates a strange look, if some how the extra border of the button can be removed, then it will be ok. I am unable to remove the extra border.
i don't want to remove the button border, i want to remove only the extra border that is created around the button after enabling xp visual styles.
please help.

May be this is the 'default button' signal - I'm not sure.
Try to add another HIDDEN button to the form and make that button the default one.

this is not the default signal, because i have four buttons on the dialog, and each button have the same problem. When the button are in classic style every thing is ok. But after enabling XP Visual Styles this problem occurs.

Hi all!
I am developing an application which will work for two monitors. The additional monitor has a touch screen. Now I want to get the force of click for it. I found it seems like some APIs can get it because some applications can respond for it. But I don't know which API(s) can do it. Is here somebody be kind to tell me? Thank you!
Sincerely!

Nope...
You hadn't get my meaning. I try to find a API to get the value of strength when I click the touch pad. Not insert mouse event into message-queue.

Sorry for my misunderstanding (read error)  . You mean touch pressure strength or, I think, sometimes called pressure size. I'm not sure that this is standard information beside location information reported by device. This theoretically possible feature may not be carried out by all manufacturers.

Thank for your reply. I had notice that Photoshop can get the pressure strength from some touch pad. So I try to find which way Adobe used to implement it. But I found nothing. I guess that is a standard of Adobe. So I will try to develop my application by the API provided from vendor. Thanks again!

I don't think such a thing is possible. A mouse button can either be in a depressed or a released state (same with a touch pad buttons, and clicks generated by touching somewhere on the touch area). Generally, there's no way to find out how "hard" a button was pressed.
If a device is sensitive to such data, and is exposing APIs to capture that information, then that would be a different story. However, it is not the case with regular mouse and touch pad devices.

Touch screen devices usually report the touch pressure.

Agree, however these shouldn't be any inbuilt functionality in the windows for same!
