search a list control

rahuljin

thanks. i am facing a new problem. i am trying to save the items of list control which are checked to a text file. here is the code ---

TCHAR ff\[100\] = {0};
CFile 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, 98);
		wcscat\_s(ff, L"\\n");
		srvc.SeekToEnd();
		srvc.Write(ff, 100);
		ZeroMemory(ff, 100);
		
	}

}

the content of the file is not right ---

A e L o o k u p S v c
þþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþþA p p H o s t S v c

there is extra space between each letter and the symble 'þ'. there is also no new line even with the use of '\n'.

Hi. I use " CString temp(ff); srvc.Write(ff, 2 * temp.GetLength() - 1); " instead of your "srvc.Write(ff, 100);", and it's works OK in my computer. Maybe you can try it, but it must not be a good solution. If it couldn't work, tell me and I would try to find another solution.

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.

rahuljin

now the content of the file is this ----

A p p M g m t A V P B F E

the content should be like this --- AppMgmt AVP BFE

rahuljin

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

carter2000

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.

carter2000

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");

rahuljin

i do some changes ----

for (int nItem = 0; nItem < 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(&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.

carter2000

It looks inefficient :)

rahuljin

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

carter2000

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

carter2000

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'.

rahuljin

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 ???

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

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();

ipList.DeleteItem(i);

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--;

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

This is the final version. :)

thanks, both the problems are solved.
