srvc.Write(ff, 2 * lstrlen(ff) - 1);
This can work in my computer too, maybe it's better than the last one I gave you.

same problem as other. there is a extra space between each letter and no new line.

My OS is winows XP.
And if I view the text by Notepad.exe, it's the same as you.
But if I use anothor software to view the text, it just be OK.

wcscat_s(ff, L"\n");
Em, try to replace the code by
1. wcscat_s(ff, L"\r\n");
2. wcscat_s(ff, L"\r");
3. wcscat_s(ff, L"\n\r");

i do some changes ----

for (int nItem = 0; nItem &lt; srvcList.GetItemCount(); nItem++)
{
	if (srvcList.GetCheck(nItem))
	{
		srvcList.GetItemText(nItem, 0, (LPTSTR)ff, 98);
		//wcscat_s(ff, L"\r\n");
		srvc.SeekToEnd();
		int i = 2 * lstrlen(ff) - 2;
		int j = 0;
		while(i)
		{
			srvc.Write(&amp;ff[j], 1);
			i--;
			j++;
		}
	}
}

the content is ---

AVP BFE BITS

if i use wcscat_s(ff, L"\r\n"), then

AVP
 þþþBFE
 þþþBITS
 þþþþ

this text file will be used by other program, therefore cant compromise with it.

It looks inefficient Smile | :)

rahuljin19-Jul-09 1:07

19-Jul-09 1:07

still there is a problem, there is no new line. i want the content of the text file like this -----

AVP
BFE
BITS

You can try veiwing the text in Edit Plus or other text edit software.

carter200019-Jul-09 1:33

19-Jul-09 1:33

You can try this, open the "srvc.txt", and select all text, and copy them, and open anthor TextEditor(Edit Plus), and paste.
If still there is no new line, then I have no ideas. It's seems that Microsoft define a new line as '\r\n', while in Unix it's '\n'.

thanks for all the support. finally it is done. the code is not that good ---

TCHAR ff[100] = {0};
CStdioFile srvc;
srvc.Open(_T("c:\\srvc.txt"), CFile::modeCreate|CFile::modeReadWrite);

for (int nItem = 0; nItem < srvcList.GetItemCount(); nItem++)
{
    if (srvcList.GetCheck(nItem))
    {
        srvcList.GetItemText(nItem, 0, (LPTSTR)ff, 100);
        int i = 2 * lstrlen(ff) - 2;
        srvc.SeekToEnd();
        int j = 0;
        while(i)
        {
            srvc.Write(&ff[j++], 1);
            --i;
        }
        ZeroMemory(ff, 100);
        srvc.SeekToEnd();
        srvc.Write("\n", 1);
    }
}

output is ---

Audiosrv      
AVP 
BFE 
BITS

also please tell me that is there a way due to which edit box control can take only numeric values and with in a bound, say 1 to 1000 only ???

19-Jul-09 15:21

you solve the problem by yourself, congratulation Smile | :)

.
maybe you can try replace the follow codes by "srvc.Write(ff, 2 * lstrlen(ff));", it works too in my computer.

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.

rahuljin19-Jul-09 22:18

19-Jul-09 22:18

still the same problem ---

ipList.DeleteItem(i);
s--;

Relpace the codes with:

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

19-Jul-09 23:34

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.

rahuljin19-Jul-09 23:45

19-Jul-09 23:45

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.

carter200020-Jul-09 0:06

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. Smile | :)

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 ??

carter200021-Jul-09 15:02

21-Jul-09 15:02

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.
