search a list control

[rahuljin]

thanks. if you didnt guide and help me, it would be impossible for me. please answer my last question. one more problem found --- in first list control, when i enter an ip say "111.111.111.111", then i cannot enter the ip address "111.111.111.11". also "111.111.111.11" deletes "111.111.111.111" from the list control. here is the code ----

BYTE m\_M1, m\_M2, m\_M3, m\_M4;
TCHAR ss\[50\] = {0};
UpdateData();
int i = -1;
LVFINDINFO temp;

ipAdd.GetAddress(m\_M1, m\_M2, m\_M3, m\_M4);
temp.flags = LVFI\_PARTIAL|LVFI\_STRING;

\_stprintf\_s(ss, \_T("%d.%d.%d.%d"), m\_M1, m\_M2, m\_M3, m\_M4);
temp.psz = ss;
i = ipList.FindItem(&temp);
 
if(radBut1->GetState())
{
	if(m\_M1 && m\_M2 && m\_M3 && m\_M4 && i == -1)
	{
		ipList.InsertItem(s++, (LPCTSTR)ss);
		ipAdd.ClearAddress();
	}
}

else if(radBut2->GetState())
{

	if(i != -1)
		ipList.DeleteItem(i);
	else 
		MessageBox((LPCTSTR)L"Error: Address not found", (LPCTSTR)L"Delete Address", MB\_ICONWARNING | MB\_OK);


	ipAdd.ClearAddress();

What's "s" means? The last index of CListCtrl? So if it's, then here

rahuljin wrote:

ipList.DeleteItem(i);

after deleting a item, you must also descend "s". I don't know if this is the reason.

[rahuljin]

still the same problem ---

ipList.DeleteItem(i);
s--;

if(i != -1) ipList.DeleteItem(i);

Relpace the codes with: if (i != -1 && lstrcmp(ipList.GetItemText(i), temp.psz) == 0) { ipList.DeleteItem(i); }

[carter2000]

BYTE m_M1, m_M2, m_M3, m_M4;
TCHAR ss[50] = {0};
UpdateData();
ipAdd.GetAddress(m_M1, m_M2, m_M3, m_M4);
_stprintf_s(ss, _T("%d.%d.%d.%d"), m_M1, m_M2, m_M3, m_M4);
int compare;
for (int i = 0; i < ipList.GetItemCount(), ++i)
{
compare = lstrcmp(ss, ipList.GetItemText(i));
if(radBut1->GetState())
{
if(m_M1 && m_M2 && m_M3 && m_M4 && compare != 0)
{
ipList.InsertItem(s++, (LPCTSTR)ss);
ipAdd.ClearAddress();
}
}
else if(radBut2->GetState())
{
if(compare == 0)
ipList.DeleteItem(i);
else
MessageBox((LPCTSTR)L"Error: Address not found", (LPCTSTR)L"Delete Address", MB_ICONWARNING | MB_OK);
ipAdd.ClearAddress();
}
}

This is the final version. :)

[rahuljin]

thanks, both the problems are solved.

BYTE m\_M1, m\_M2, m\_M3, m\_M4;
    TCHAR ss\[50\] = {0};
UpdateData();
int i = -1;
LVFINDINFO temp;

    ipAdd.GetAddress(m\_M1, m\_M2, m\_M3, m\_M4);
temp.flags = LVFI\_PARTIAL|LVFI\_STRING;

\_stprintf\_s(ss, \_T("%d.%d.%d.%d"), m\_M1, m\_M2, m\_M3, m\_M4);
temp.psz = ss;
i = ipList.FindItem(&temp);
 
if(radBut1->GetState())
{
	if(m\_M1 && (i == -1 || lstrcmp(ipList.GetItemText(i, 0), temp.psz) != 0) )
	{
		ipList.InsertItem(s++, (LPCTSTR)ss);
		ipAdd.ClearAddress();
	}
}

else if(radBut2->GetState())
{

	if (i != -1 && lstrcmp(ipList.GetItemText(i, 0), temp.psz) == 0)
	{
		ipList.DeleteItem(i);
		s--;
	}

	else 
		MessageBox((LPCTSTR)L"Error: Address not found", (LPCTSTR)L"Delete Address", MB\_ICONWARNING | MB\_OK);


	ipAdd.ClearAddress();

		
}

I think your code still has some problems. Consider the situation below: There are two items in CListCtrl. 111.111.111.111 111.111.111.11 And you enter 111.111.111.11 to insert the new item, see what happen. If I am right, it will insert successfully!!That may not be what you want.

[rahuljin]

got another solution ---

temp.flags = LVFI_STRING;

and everything becomes right.

[carter2000]

You are right. :)

[rahuljin]

in that case, 'i' will not be -1 and lstrcmp(ipList.GetItemText(i, 0), temp.psz) will be equal to zero because the item text and temp.psz will be same.

[carter2000]

Before you changed the "temp.flags = LVFI_PARTIAL|LVFI_STRING;" to "tem.flags=LVFI_STRING;", it's a wrong case exactly. But now it isn't. :)

[carter2000]

:)

LVFINDINFO temp;
CString ff;
temp.flags = LVFI\_STRING | LVFI\_PARTIAL;    
CStdioFile fileh;
fileh.Open(L"C:\\\\srvc.txt", CFile::modeRead);	
int i;
do	
{		
    if(fileh.ReadString(ff)== NULL) 		
    {			
        break;		
    }	
    temp.psz = ff.GetBuffer();	
    i = m\_objListCtrl.FindItem(&temp);
    if(lstrcmp(m\_objListCtrl.GetItemText(i, 0), temp.psz) == 0)	
    {		
        m\_objListCtrl.SetCheck(i, TRUE);	
    }		
}
while(ff.GetBuffer() != NULL);		
fileh.Close();

This can work in my computer, but I don't guarantee it could work in your computer. And by the way, I am in school now, but tomorrow I'll back home(There is no computer in my house :) ). It means I could not use computer for a long time. And I can't solve problem together with you, I'm sorry for that..

hello, is it possible to make edit control to take only numeric values and limited digits only ??? i have an edit control which is used for the port number, so i want that the user can enter only numeric value and 5 digits. any suggestion ??

[carter2000]

Yes, it can. you can set the property of the control to gain what you want. I forget the details, but I am sure it can. My computer do not have a compiler, so I can't take a test.

[carter2000]

If your compiler is VS200X, you can right click the control, and click the "Add Variable" in the pop menus. Then it will pop out a window, and you can set the property in it. If your compiler is VC++6.0, select the control, and in the "View->Class Wizzard->Add Member", I hope I don't misremember.

[rahuljin]

i have vs2008. i set the limit by using this code ---

portID.SetLimitText(5);

only numeric problem is left.
