We have no way of guessing what this could mean. Please explain clearly, with code extracts, what you are trying to do and what results you are seeing.

One of these days I'm going to think of a really clever signature.

sorry for not explaining m_listCrl = DEBUG_NEW CListCtrl; if(!m_listCrl->Create(WS_CHILD|WS_VISIBLE|LVS_REPORT|LVS_AUTOARRANGE,/*CRect(65, 100, 960, 448)*/CRect (60, 105, 954, 435),this,IDC_LIST_CTRL)) { TRACE ("\nDBG:\tFailed to create window object for List ctrl at line %u in %s.", __LINE__, __FILE__); return -1; } GetPrivateProfileString (_T ("Remo Eraser"), _T ("IDS_CLOUMN1"), NULL, (LPWSTR)szNewText, sizeof(szNewText), m_szPath); m_listCrl->GetHeaderCtrl(); m_listCrl->InsertColumn(1,(LPWSTR)szNewText,LVCFMT_LEFT,75+75+25+50+25+25+25,-1); GetPrivateProfileString (_T ("Remo Eraser"), _T ("IDS_CLOUMN2"), NULL, (LPWSTR)szNewText, sizeof(szNewText), m_szPath); m_listCrl->InsertColumn(2,(LPWSTR)szNewText,LVCFMT_CENTER,75+75+25+50+25+25+25+10,-1); GetPrivateProfileString (_T ("Remo Eraser"), _T ("IDS_CLOUMN3"), NULL, (LPWSTR)szNewText, sizeof(szNewText), m_szPath); m_listCrl->InsertColumn(3,(LPWSTR)szNewText,LVCFMT_CENTER,75+75+25+50+25+25+10-1); m_listCrl->InsertItem(0,File_Name,NULL); m_listCrl->SetItemText(0,1,m_Filepath); m_listCrl->SetItemText(0,2,_T("10KB"));

here is the code am adding the file name and file path in an Clist ctl. am dont want to add the same file name or path in an list . i tried with FindItem // info.flags =/* LVFI_PARTIAL|LVFI_STRING*/LVFI_PARAM; // info.psz = m_Filepath; // Delete all of the items that begin with the string. // index = m_listCrl->FindItem(&info); // while ((index = m_listCrl->FindItem(&info))!= -1) // { // MessageBox(_T("File Already exists "),_T("Inforamtion"),MB_ICONINFORMATION); // m_listCrl->DeleteItem(index); // // } <

Take care, CListCtrl::FindInfo[^] search in list only in items (not in subitems), and you want to search in subitems ... so, you have to loop in all list control and test if subitem 'Path' is already there ...

First comment, please use <pre> tags around code snippets, as I have done below. Your LVFINDINFO.flags are wrong, and should be as follows:

info.flags = LVFI_STRING;
info.psz = m_Filepath;

index = m_listCrl->FindItem(&info);
if (m_listCrl->FindItem(&info) == -1)
{
// File path not found
}

One of these days I'm going to think of a really clever signature.

Are you seriously doing this in production code or is this just a personal project?

This should be:

int nItem = m_listCrl->InsertItem(0, File_Name);
m_listCrl->SetItemText(nItem, 1, m_Filepath);
m_listCrl->SetItemText(nItem, 2, _T("10KB"));

You should be using some other data structure that is better suited for searching, or one that doesn't allow duplicates to begin with. Populate the list control from that.
