What we desire is to position the list box to a specific location. You must know the exact entry text to use this feature. To utilize a feature to position the list box to the first item containing the search string the following code provides the functionality.

int iend = lbxRecs->GetCount();
int ii = 0;
while (ii < iend)
{
string buf;
buf = lbxRecs->GetString(ii).ToStdString();
if (buf.find(sv) < buf.length())
{
lbxRecs->SetSelection(ii);
ii = iend + 1;
}
ii++;
}
}

After the string is specified the list is positioned as follows.
From this point simply traverse in a downward direction of revealing the remaining entries.
