hi,
thanks. it sounds u r very special in barcode.

do all barcodes have same size in height (and width?), so barcode readers can read formats properly?
what does UPC stand for?

can you give me some good links to study? google offers too many links to choose.

No, not at all. The size is determined by several factors like how much room in the paper can be devoted to it, how far away the scanner will be. As long as the barcode is formatted properly, and it is within rage of the scanner, it should be able to be read.

Universal Product Code.

It all depends on what in particular you are looking for. Here is a starting point.

Color of scrollbar of a listbox

Does anyone know how to set the color of the scrollbar of a listbox. I'm using win32. I've already tried several WM_CTLCOLOR... messages, but this did not work.
Changing the colors of buttons and other controls works fine.

Their is no way to change the color of scroll bar in a listbox. The scroll bar in it is Build in.

u can either hide the default scroll bar and put urs

Another method is

You can't (legally) use Detours in a commercial product - I don't even think you can use it in a free product (again, legally). I haven’t read the license in a while but from memory it’s quite restrictive – I think you can use it for “research” purposes. Also it doesn't work properly on Win95/98/ME (but who cares?!?).

I'd be surprised if you couldn't use subclassing to change the colour of the scrollbars.

But we cannot take the handle of the default scrollbars. It is only a drawing, not a window, right? Further more the system paints it directly, in many cases( like thumb positioning, etc. ). So we cannot use the OnPaint also. That is why the detours is used.

set the color to a Button

Hi,
Is it possible to set the color to a button in a dialog based application?
I tried using CTLCOLOR_BTN unsuccessfully.

The code which i tried is given below..

HBRUSH CMyDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
if (CTLCOLOR_BTN == nCtlColor)
// It worked when i used CTLCOLOR_DLG to change the color of the DialogBox
{
hbr = ::GetSysColorBrush(1);
}

return hbr;
}

Thanks in Adavance..
Chetan.

I think you want to change color from button you need to
derived from CButton and use WM_DRAWITEM
But for best way you can go examples in CodeProject and
you find your answer

The documentation states that WM_CTLCOLORBTN (which you're handling indirectly via the MFC plumbing when you handle the WM_CTLCOLOR message) only works you owner drawn controls - Which basically makes it useless as then you have to draw it yourself. You’re not doing anything wrong; this technique simply doesn’t work.

simplest way is to Inherit a CButton then darw it on WM_PAINT or OnPaint(...), very easy.

Button Doesn't support Changing color through WM_CTLCOLOR Message!.. you need to handle WM_DRAWITEM MESSAGE by Subclassing the Button...

Hi!

I've built MFC project with VS MFC wizzard, and have included my own source. It's working fine on my computer, but on other computer isn't, because it doesn't have reqired DLLs.

My question is, how to attach necessery DLLs to my MFC project, to run it on other comuper whitch doesn't have reqired DLLs?

Hope You got the point.

Looking forward to hearing from You.

Thanks!

Try statically linking the MFC library to your DLL. You can do this in Main Menu: Project - Project Properties - Configuration Settings - General - MFC usage. Change this from shared MFC DLL to statically linking the MFC library.

Best regards

_outp(0x64, 0xAD);
and

do the same... but what do they do??

You need to copy the required dlls to the other computer's windows directory. This is what installers are used for.

Try this installer its free and powerfull

you have build the exe in *debug* mode, change to *release* mode and to test simple copy the required dlls (mfc70.dll , msvcr70.dll) without the 'd', if they are not there already
