I got another problem. When I click a thumbnail image, the
"hitinfo.flags != LVHT_ONITEMSTATEICON" still true, and the program
returned. I don't know if I use the wrong way?
Below is my source code:
void CThumbView::OnLvnItemchanged(NMHDR *pNMHDR, LRESULT *pResult)
{
LPNMLISTVIEW pNMLV = reinterpret_cast<LPNMLISTVIEW>(pNMHDR);
// TODO: Add your control notification handler code here
CListCtrl& ListCtrl = GetListCtrl();
LVHITTESTINFO hitinfo;
*pResult = 0;
//Copy click point
hitinfo.pt = pNMLV->ptAction;
//Make the hit test...
int nItem = ListCtrl.HitTest(&hitinfo);
//No click on image item, return
if(hitinfo.flags != LVHT_ONITEMSTATEICON)
return;
//Image item hit
CePhotoSyncDoc* pDoc = (CePhotoSyncDoc*)GetDocument();
ASSERT_VALID(pDoc);
pDoc->SelectItem( pNMLV->iItem );
pDoc->UpdateAllViews(this, UPDATE_PREVIEW);
}

Thanks a lot.

You could check if the user clicked on the state icon:
NMLISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
LVHITTESTINFO hitinfo;
*pResult = 0;
//Copy click point
hitinfo.pt = pNMListView->ptAction;
//Make the hit test...
int nItem = m_cList.HitTest(&hitinfo);
if(hitinfo.flags != LVHT_ONITEMSTATEICON)
return; // Didn't click on an icon

I use CListView to draw the thumbnail of a image list. And I want to
add
the
checkbox for the image list. When I select a thumbnail, the CListView
will
trigger the "OnLvnItemchanged" event to let another view to show the
preview
image of the selected image.
My problem is that when I use
"ListCtrl.SetExtendedStyle(ListCtrl.GetStyle()|LVS_EX_CHECKBOXES )",
the
"OnLvnItemchanged" is trigger by the initial operation for checkbox.
This
is
not I expected, how can I solve the problem?
Thanks for your help.
