I am seeing an unusual behavior with a CListCtrl API on a CFileDialog, only
on VISTA. I have a call like GetItemData on the list control which is
supposed to return the item as a LPCITEMIDLIST but it always returns NULL
only on a VISTA OS. Windows XP is fine.
Can anyone help me on this one?

Code's here
LPNMLISTVIEW phdr = NULL;
phdr = reinterpret_cast<LPNMLISTVIEW>(lParam);
CListCtrl lc;
lc.Attach(phdr->hdr.hwndFrom);
LPCITEMIDLIST pidl = (LPCITEMIDLIST) lc.GetItemData(phdr->iItem);
SHGetPathFromIDList(pidl, str);
pidl is NULL. Hence i am not able to get File Path.
if i use GetItemText, i will get only file name without extension.
Any Solution. Or any other way to follow..
This works in XP but not in Vista.

This is in response to what (notification) message? Are you using a hook with CFileDialog? Do you have file extensions (in Windows Explorer) turned off?

Yes, you are right..
I am using Hook and OnNotify.

Which LVN_xxx notification?

At the point pidl is NULL, what is the value of phdr->iItem?

phdr->iItem is showing corect value... The value depends upon which image i select.

Is it ever -1?
Are you verifying that phdr->hdr.code is equal to LVN_ITEMCHANGED?

ya its like
if (pLVHdr->hdr.code == LVN_ITEMCHANGED && (pLVHdr->uChanged & LVIF_STATE))
and iItem is never -1

Instead of LPNMLISTVIEW, i used LPLVITEM.
LPLVITEM lv = = reinterpret_cast<LPLVITEM>(lParam);
lv.lParam is also zero.

So have you tried casting to a LPNMLISTVIEW instead?

I have casted to LPLVITEM.
I think it cannot convert from 'LPNMLISTVIEW' to 'LPLVITEMW'.

Why would you think this would work? They are two different structures. Use LPNMLISTVIEW like the documentation states.

I am afraid, i am confusing you.. I said instead of
LPNMLISTVIEW pLVHdr = reinterpret_cast<LPNMLISTVIEW>(lParam);
i used
LPLVITEM pLVHdr = reinterpret_cast<LPLVITEM>(lParam);
|

But why, since LPNMLISTVIEW and LPLVITEM are two different structures. The documentaton plainly states that the lparam that accompanies the LVN_ITEMCHANGED notificaton is a pointer to a NMLISTVIEW structure, not a pointer to a LVITEM as you are trying to use.
That said, I do not know why your code "works" on Windows XP but not on Vista. I do not have the latter to test on.

I think, i am disturbing you.
Anyways Thank you very much for your time and help.

pidl = (LPCITEMIDLIST) ctl.GetItemData(pLVHdr->iItem);
SHGetPathFromIDList(pidl, tszBuffer);
pidl is '0x000000'. Hence tszBuffer is "".

As i said, GetItemData returns NULL, hence i used SendMessage() but in vain.
