try UpdateWindow() api, it will post WM_PAINT message to Listctrl to redraw it self!

I am asking you to call CListCtrl->UpdateWindow()

As your running the CListCtrl in a CFormView you are probably DDX'ing the control to assign it to a member variable. In your header you will have somwthing like:
CListCtrl m_myList;
In the .cpp file:
DDX_Control(pDX, IDC_LIST1, m_myList);
To cause the window to re-draw itself you will need to call the UpdateWindow function as follows:
m_myList.UpdateWindow();
If you vote me down, my score will only get lower

There is no easy place that I can think of where you can catch the WM_VSCROLL event of the CListCtrl.
I would suspect the problem lies in the NM_CUSTUMDRAW handler for the items being drawn.
If I remember correctly a CLIstCtrl uses the ScrollWindow function and then gets you to draw the new items which have scrolled into view. The ScrollWindow function only scrolls the areas for which a column has been created for. Options:
1. Change your custon draw function to limit the background colour drawing to the width of the created columns so you do not draw in the unused blank area.
2. Try changing the style of the CListCtrl to included the LVS_EX_FULLROWSELECT style.
m_list.SetExtendedStyle(m_list.GetExtendedStyle() | LVS_EX_FULLROWSELECT);
This may cause the control to scroll the entire client area correctly.
If you vote me down, my score will only get lower

Hi all,
At one point of my application(using vc++) I need to restart the system. That I am doing like-
BOOL CtestShutDlg::RestartSystem()
{
HANDLE hToken;
TOKEN_PRIVILEGES tkp;
// Get a token for this process.
if (!OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
return( FALSE );
// Get the LUID for the shutdown privilege.
LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME, &tkp.Privileges[0].Luid);
tkp.PrivilegeCount = 1; // one privilege to set
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
// Get the shutdown privilege for this process.
AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, (PTOKEN_PRIVILEGES)NULL, 0);
if (GetLastError() != ERROR_SUCCESS)
return FALSE;
// Shut down the system and force all applications to close.
if (!ExitWindowsEx(EWX_REBOOT,
SHTDN_REASON_MAJOR_OPERATINGSYSTEM |
SHTDN_REASON_MINOR_UPGRADE |
SHTDN_REASON_FLAG_PLANNED))
return FALSE;
return TRUE;
}
It restart the system immediately when this function called up. I want that there should be some kind of warning or any type of message to user "your system need to be reboot now" like that before rebooting.
Please suggest me some way how can I do this.
Thanks

Place a MessageBox before Rebooting, based on user selection, you can implement rebooting logic like :-
if(MessageBox("Do You want restart the computer","",MB_YESNO)== IDYES))

You can use WMI.

And here is WMI class that you may be looking for with all the hdd information

Hi,

Just as a query, you would be returning a different color brush from WM_CTLCOLOR in case the control is a group box. But this would only paint the area behind the caption of the group box. The OP wants to fill the background of the group box, if my understanding is correct.
Somethings seem HARD to do, until we know how to do them.

Why? don't they fit to your need. You can extract the code for painting the group box background? or do you need some code that you can directly use...

The problem here is that the static labels which i am having as a part of the GroupBox is either appearing without their background color changed.
In some cases the static labels are hidden as the group box is being repainted.
