Hi all,
What function can I use to monitor whether or not a computer has network connectivity. For example, if the network cable was unplugged the function would trigger. I suppose I should do this in a thread?
Many thanx

Thanx for your reply..
BOOL InternetGetConnectedState(
OUT LPDWORD lpdwFlags,
IN DWORD dwReserved
);
Retrieves the connected state of the local system.
Returns TRUE if there is an Internet connection, FALSE otherwise.
Will this work for a local (LAN) connection aswell ?

Sorry, I didn't read your question good enough before answering.
If you know for sure that the computer in question is connected to Internet via the LAN-connection, you should be able to use either InternetGetConnectedState() or InternetGetConnectedStateEx()
Check for INTERNET_CONNECTION_LAN
Else, I found this at MSDN:
1.
Use IsNetworkAlive()
2.

Hi,
When i change the background color of my dialog, along with that the color of the edit box in my dialog is changing.. but i want the editbox color to be white only..
Is there anyway to do?
Is there any function like in the case of listcontrol(SetBkColor()) to get the color of Editbox to the color i want to.

I used following function
HBRUSH CFileopenDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
return m_brush;
}
along with the line m_List.SetBkColor(RGB(255, 255, 255));
in oninitdialog().

I'm not sure, how you have done it, but modify your code to,
CFileopenDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
return m_brush;
}</blockquote>
To skip edit control painting do this,
HBRUSH CFileopenDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
m_brush= CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
if (nCtlColor == CTLCOLOR_EDIT)
{
return brush
}
else
{
}
return m_brush;
}

Hope the m_List is your CEdit control.

Instead of simply returning m_brush(hope this the brush to paint the dialog background). Try this,
CFileopenDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
if (CTLCOLOR_EDIT != nCtlColor)
return m_brush;
return hbr;
}
The above change the background color for all the controls in the dialog except for the CEdit controls.
If you want to change the color only to the dialog then change the 'if' condition as below
if (CTLCOLOR_DLG == nCtlColor)

Default color of editbox is white but if you want to change color of editbox use of WM_CTLCOLOREDIT
|
|
|
|

Over ride WM_ERASEBKGND and put this code over there.
CPen myPen;
int i =100;
CRect rect ;
myPen.CreatePen(PS_SOLID, 1, RGB ((i * 4),0,0));
CPen *oldPen = pDC->SelectObject(&myPen) ;
GetClientRect(&rect);
for(i = 0 ; i <= rect.bottom;)
{
pDC->MoveTo(0, i);
pDC->LineTo(rect.right, i);
pDC->SelectObject (&myPen);
}
pDC->SelectObject(oldPen) ;
return TRUE ;
The edit box would not be painted to match the dialog back color and would show as white. See if this helps

if (pWnd->GetDlgCtrlID() == IDC_EDIT1) would be better.
