I have a CListCtrl, with the extended style LVS_EX_SUBITEMIMAGES enabled
to let me have images on the subitems.

Now is it possible the have different images in each column on the same
row? No matter what I do, I always get the same image in every column.

I've tried using the I_IMAGECALLBACK callback, then setting the image to
something different based on what subitem is being drawn, but still no luck.

Any ideas?

Is this what you are doing to set the image of the subitem?

SetItem(nItem, nSubItem, LVIF_IMAGE, NULL, nImageIndex, 0, 0, 0);

Are you sure you are passing the correct image id?

If you can't get it working take a look at this:

I've been using the LVITEM structure to add entries, like this:-

CString number;
LVITEM lvitem;
lvitem.iItem = 0;
lvitem.mask = LVIF_TEXT | LVIF_PARAM | LVIF_IMAGE;
lvitem.lParam = si.m_ID;
lvitem.iImage = si.m_GameVersion;
lvitem.iSubItem = kID;
number.Format(_T("%d"), si.m_InGameID);
lvitem.pszText = number.GetBuffer(number.GetLength());
lvitem.iItem = m_ResultsCtrl.InsertItem(&lvitem);

lvitem.mask = LVIF_TEXT;
lvitem.iSubItem = kSongTitle;
lvitem.pszText = si.m_SongTitle.AllocSysString();
m_ResultsCtrl.SetItem(&lvitem);

lvitem.mask = LVIF_TEXT | LVIF_IMAGE;
lvitem.iSubItem = kStatus;
lvitem.pszText = L"";
lvitem.iImage = 12;
m_ResultsCtrl.SetItem(&lvitem);

This was my first test. 'si' is just another class of mine which I grab
values out of to present in the CListCtrl, which is the var
m_ResultsCtrl. The iSubItem values are just from an enum.
The above code gives me the different and correct icons in the far left
column (for m_GameVersion), however I don't get the same icon in the
kStatus column, I just get the same icon as the first column.

I then tried replacing the latter chunk of code with:-

lvitem.mask = LVIF_TEXT | LVIF_IMAGE;
lvitem.iSubItem = kStatus;
lvitem.pszText = L"";
lvitem.iImage = I_IMAGECALLBACK;
m_ResultsCtrl.SetItem(&lvitem);

Then in the class derived from CListCtrl I have this function:-

void CSongSelectListCtrl::OnLvnGetdispinfo(NMHDR *pNMHDR, LRESULT *pResult)
{
NMLVDISPINFO *pDispInfo = reinterpret_cast<NMLVDISPINFO*>(pNMHDR);

LV_ITEM *pItem = &((LV_DISPINFO*)pNMHDR)->item;

if( pItem->mask & LVIF_IMAGE )
{
if ( pItem->iSubItem != CMainDialog::kID )
pItem->iImage = I_IMAGENONE;
else if ( pItem->iSubItem == CMainDialog::kStatus )
pItem->iImage = 12;
}
*pResult = 0;
}

Again I get the same results as before and completely ignores what value
I give the iImage. Although it does seem to pay attention to the
I_IMAGENONE constant. Any positive value for any column just gives an
icon the same as the first column in the control.

Stepping through with a debugger, on entry to the above function, iImage
is always the value of the first column.

Any more ideas?

I'll have a look at the ReportControl you recommend in the mean time though.
