ListView OnGetdispinfo query

[MikeL]

When using OnGetdispinfo(NMHDR* pNMHDR, LRESULT* pResult) with ListView the documentation says you can use LVIF_DI_SETITEM to tell the ListView to store the information for an item and not to request it again.

How!

Cheers in advance...

Hi!
Did you try this?

[ccode]
void CMyList::OnGetdispinfo(NMHDR* pNMHDR, LRESULT* pResult)
{
LV_DISPINFO* pDispInfo = (LV_DISPINFO*)pNMHDR;
// TODO: Add your control notification handler code here
if(pDispInfo->item.mask & TVIF_IMAGE)// Check for the info he needs
{
pDispInfo->item.iImage=0; // Set the info he needs

pDispInfo->item.mask |=LVIF_DI_SETITEM;
}
[...]
}

I hope it helps!

Yeah, that is exactly how I thought it should work, but the ListView still insists on requesting for the same information again and again (ie. every time the cursor is moved)

Do you (does anyone) have a working example?
