Memory Monitoring

Hi all,

I would like to know if someone could give me some advise about monitoring a computers memory i.e. if the computer runs out of resources I want to restart the computer, (but only if the memory resource are insuffient).

Would it be a good idea to use the function QueryMemoryResourceNotification(), or is there another function I not aware of. Confused | :confused:

Thanx in advance

tool tip problem in custom activex control

A activex control was created that gets called through a php page with ms word 2003 embeded in a dialog box, in the activex control.
a tool bar is also created in the derivation of MyDialog::OnInitDialog() with some buttons in the dialog box like this:

if (!m_ToolBar.Create(this, WS_CHILD | WS_VISIBLE | CBRS_TOP | CBRS_TOOLTIPS | CBRS_FLYBY) || !m_ToolBar.LoadToolBar(IDR_MAINFRAME))

{
TRACE0("Failed to create toolbar\n");
return -1; // fail to create
}
// Move the toolbar so it is VISIBLE on the screen.
CRect rc;
GetClientRect(&rc);
rc.bottom = rc.top + 34;
rc.bottom = rc.left + 30;
m_ToolBar.MoveWindow(&rc);
m_ToolBar.ShowWindow(SW_SHOW);

RepositionBars(AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0);
EnableToolTips(true); //enable tool tips

//////////////////in its message map i'm calling OnToolTipNotify////////

BEGIN_MESSAGE_MAP(CDlgDocument, CDialog)
ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTW, 0, 0xFFFF, OnToolTipNotify)
ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTA, 0, 0xFFFF, OnToolTipNotify)
END_MESSAGE_MAP()

///////declaration of OnToolTipNotify in the 'void MyDialog:public CDialog'///

afx_msg BOOL OnToolTipNotify(UINT id, NMHDR *pNMHDR,LRESULT *pResult);

///////////and definitition of OnToolTipNotify is://////

BOOL CDlgDocument::OnToolTipNotify(UINT id, NMHDR *pNMHDR,LRESULT *pResult)
{
// need to handle both ANSI and UNICODE versions of the message
TOOLTIPTEXTA* pTTTA = (TOOLTIPTEXTA*)pNMHDR;
TOOLTIPTEXTW* pTTTW = (TOOLTIPTEXTW*)pNMHDR;

TCHAR szFullText[256];
CString strTipText;
UINT nID = pNMHDR->idFrom;
if (pNMHDR->code == TTN_NEEDTEXTA && (pTTTA->uFlags & TTF_IDISHWND) ||
pNMHDR->code == TTN_NEEDTEXTW && (pTTTW->uFlags & TTF_IDISHWND))
{
// idFrom is actually the HWND of the tool
nID = ::GetDlgCtrlID((HWND)nID);
}

if (nID != 0) // will be zero on a separator
{
// don't handle the message if no string resource found
if (AfxLoadString(nID, szFullText) == 0)
return FALSE;

// this is the command id, not the button index
AfxExtractSubString(strTipText, szFullText, 1, '\n');
}

#ifndef _UNICODE
if (pNMHDR->code == TTN_NEEDTEXTA)
lstrcpyn(pTTTA->szText, strTipText, _countof(pTTTA->szText));
else
_mbstowcsz(pTTTW->szText, strTipText, _countof(pTTTW->szText));
#else
if (pNMHDR->code == TTN_NEEDTEXTA)
_wcstombsz(pTTTA->szText, strTipText, _countof(pTTTA->szText));
else
lstrcpyn(pTTTW->szText, strTipText, _countof(pTTTW->szText));
#endif
*pResult = 0;
return TRUE; // message was handled
}

i've tried most of the ideas on the net but couldn't view the tool tip.
kindly help me out how tool tips can be displayed for the tool bar
buttons?
note: the activex control is executing in the internet explorer 6.0.

CEdit has SetSel() method. Use this method to select the text. To select the entire content in use SetSel as,

SetSel(0, -1)

Hi,

I wish to the set focus in an edit box by calling another function. Currently I am using SetFocus() but I find that the default text is not highlighted, instead the cursor is at the beginning of the text box. I was wondering how I can get the default text highlighted in the text box when I use my function.

Thank you for any suggestions Smile | :)

Hi,

I want to browse the list of port name to find the port com number of my serial gadget.

I found examples in DDK, but i want simple code to be integrated in my Visual C++ application.

Regards.

This should do the trick.

CString strPortName, strDesc;
	CStringList slPorts;

	unsigned long lNeeded = 0;
	unsigned long lReturn = 0;
	PORT_INFO_2* piPorts = NULL;

	EnumPorts (NULL, 2, NULL, NULL, &lNeeded, &lReturn);
	
	if (lNeeded > 0 && GetLastError () == ERROR_INSUFFICIENT_BUFFER)
	{
		piPorts = new PORT_INFO_2[1 + (lNeeded / 20)];
		if (EnumPorts (NULL, 2, (BYTE*)piPorts, lNeeded, &lNeeded, &lReturn) != 0)
		{
			for (unsigned long nPort = 0; nPort < lReturn; nPort++)
			{
				strPortName = (char*) piPorts[nPort].pPortName;
				strDesc = (char*) piPorts[nPort].pDescription;

				strPortName.MakeUpper ();
				strDesc.MakeUpper ();

				if (strPortName.Left (3) == _T("COM") || strDesc == _T("COMMUNICATIONS PORT"))
					slPorts.AddTail (strPortName);
			}
		}

		delete [] piPorts;
	}

Ports (COM & LPT)

I want to trigge with Gadget Serial
