Hello Maximilien,
i have two kind of lists, one as CGridCtrl and one as CListCtrl.
I know now how to use virtual lists in CListCtrl, i read data from file, line by line and show them
in my CListCtrl:
my solution now is:
read all in an array
and then fill CListCtrl form this array
but i need it in this order(and here i have problems):
read line
show line
read line
show line
because every time when i want to add items to list i recive an exception(owner data problem)
Example for CGridCtrl(MFC Grid by Chris Maunder) i dont have yet! 
regards
termal

Hi,
i create a own class from CObject, looks like this sample:
class CMyObClass : public CObject
{
CString csFName;
CString csLName;
CString csStreet;
int iAge;
}
i make a new question, is there any "musts" how to store and show list items?
in this sample from your answer the developer use vector to hold items, is that the only way, or,
i can use maps like CMapStringToOb for that??
thanks very much!

I have an MFC application with two threads built in Visual Studio 6.0. The debug version is running fine. But the Release version is giving an error. Access violation in OxC000005(NTDLL.DLL):Access Denied. Is this a problem which has arised due to the build settings or can it be due to the code??

Surviving the Release[^] is certainly the best article I read over here about such problems arising when migrating to Release mode compilations...

The following code is used to convert an item identifier list to a file system path.
LPNMLISTVIEW phdr = NULL;
lparam is assigned to phdr with cast.
CListCtrl lc;
lc.Attach(phdr->hdr.hwndFrom);
LPCITEMIDLIST pidl = (LPCITEMIDLIST) lc.GetItemData(phdr->iItem);
SHGetPathFromIDList(pidl, str);
But SHGetPathFromIDList returns FALSE and str has nothing.
Any error in code?
plz help me.
Thanks.

Hi,
Maybe your buffer is not big enough or pidl may not be a valid LPCITEMIDLIST.
In case str is a CString you should allocate a buffer first being MAX_PATH in size.

its allocated MAX_PATH.

Ya, pidl is NULL. But pidl is NULL only in Vista not in XP.
Any Solution.

Please refer this[^] for more information on Vista.

Where do you call SetItemData()? Since the thing being returned by GetItemData() is not a valid PIDL, the place to look is your SetItemData() call.
