search a list control

[carter2000]

Hi, GetItem has the declaration like this:BOOL GetItem(LVITEM* pItem) const; So it can't accept a int type parameter. besides, it return a BOOL value; I think you must misunderstand the function.

In addition to the above comment, you can use the FindItem() function of list control directly. No need to loop.

thanks for the reply. please tell me how to search an item in list control.

[carter2000]

Use FindItem() to get the index of the list control you want. int FindItem(LVFINDINFO* pFindInfo, int nStart = -1) const; ipAdd.GetAddress(m_M1, m_M2, m_M3, m_M4); LVFINDINFO temp; temp.flags = LVFI_PARTIAL|LVFI_STRING; _stprintf_s(temp.psz, _T("%d : %d : %d : %d"), m_M1, m_M2, m_M3, m_M4); //I'm not sure if this would work int i = ipList.FindItem(&temp);

[rahuljin]

this code is giving error ----

_stprintf_s(temp.psz, _T("%d : %d : %d : %d"), m_M1, m_M2, m_M3, m_M4);

error

error C2664: 'int swprintf_s(wchar_t *,size_t,const wchar_t *,...)' : cannot convert parameter 1 from 'LPCWSTR' to 'wchar_t *'

thanks for the reply.

[carter2000]

I'm sorry for that. You can try the code below. wchar_t ss[100]; _stprintf_s(ss, _T("%d : %d : %d : %d"), m_M1, m_M2, m_M3, m_M4); //I'm not sure if this would work temp.psz = ss; Hope it can run.

thanks, it is working now. also, in the second list control in application, there is check box in first column for ach item. please tell me how to get the items which are checked ?

[carter2000]

But I know you can add 'LVN_ITEMCHANGED' Message handling functions for the CListCtrl, when checkbox's state is changed, the function would be activated, and you can check if the checkbox is be selected in the Message handling functions.

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 ---

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.

[carter2000]

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.
