See

HBRUSH CDialogDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

pDC->SetTextColor(RGB(20,120,220));//text
pDC->SetBkColor(RGB(20,120,220));//background

You must insert WM_CTLCOLORmessage to your program and for radio button its working Wink | ;)

and again a short help

BEGIN_MESSAGE_MAP(CDialogDlg, CDialog)
ON_WM_CTLCOLOR()
END_MESSAGE_MAP()

HBRUSH CDialogDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

pDC->SetBkColor(RGB(20,120,220));
pDC->SetTextColor(RGB(255,255,220));

	return hbr;
}

/////////////header file/////////////
public:
afx_msg HBRUSH OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor);

Any way to run an exe at logoff!

Hello everybody!

Is there any specific way to run an exe when a system wants to logoff!
Or will the system forcefully closes all active applications before logoff?

You can get a notification to an already running exe but i am not aware of any method to run an exe.

Systems send WM_QUERYENDSESSION to each application window when log off process is initiated. You can do any specific task here. Returning FALSE in response to this message causes log off operation to stop.

Question related to List box control.

Hi all.

How can I get the pointer/handle to the horizontal and vertical scroll bars from list box?
I tried it using…

CListBox *pList = (CListBox *) GetDlgItem(IDC_LIST);

if( NULL == pList->GetSafeHwnd() )
return;
CScrollBar* pVertScroll = pList->GetScrollBarCtrl(SB_VERT ) ;
But it is returning NULL.

Also how I can trap the events like WM_MOUSEMOVE over scroll bar arrows?

Thanks

Did you see MSDN?
From the MSDN
This member function does not operate on scroll bars created when the WS_HSCROLL or WS_VSCROLL bits are set during the creation of a window

Sure.

In my application I have added a list box on a dialog box. This list contain so many numbers of string elements that user has to scroll too much to see all the contents.

I want to minimize the scrolling efforts of user and I want to provide auto scrolling to the list box. The elements of the list box should get scroll automatically when user movies the mouse pointer over scroll bar arrows of the list box.

For that I want to …
1. Get the pointer or handle to the Scroll bars of list control.
2. Trap the event when mouse is moved over the scroll bar arrows and kept there for some predefined time say 2 sec.
3. Scroll down or up the list with some specified speed.

How I can proceed to achieve these sub tasks?

Thanks

Add a member variable to your radio button, which is of type CxShadeButton. For example, may it be m_radio1. Now call SetTextColor, from InitDialog as follows:

m_radio1.SetTextColor(RGB(100,100,100));
