Virtaul listview?

Dear All,

I know a control item which is called virtual listview is existed and I have read the article posted at the online library at microsoft.

My operating system is Window 98, the version of the following files

comctl32.dll is 4.72.3110.1
shell32.dll is 4.72.3110.6
shlwapi.dll is 4.72.3110.0

Also, I am using the professional edition of VC5.0 to develop my application.

How can I develop a virtual listview under this environment?
My project's view class is CFormView. I haev tried to add a listview at the resource editor but it doesn't contain the property LVS_OWNERDATA...Also, I cannot use the function SetItemCountEx(..).

Thanks!!!

Dear pau_serra,

My project's view class is CFormView. How can I modify your code to implment the same thing?

At the function PreCrateWindow, I have tried to modify the following code from:

cs.style&=~LVS_TYPEMASK;
cs.style = cs.style | LVS_REPORT | LVS_SHOWSELALWAYS | LVS_OWNERDATA;

to
CListCtrl m_list1;
DWORD ListStyle = LVS_REPORT;
m_list1.ModifyStyle(ListStyle,LVS_REPORT|LVS_SHOWSELALWAYS|LVS_OWNERDATA,0);

and put this in the OnInitialUpdate(..) Function.

Others are same, however, I get an debug assertion error.......

How can I modify your code?

Thanks!!!

Ok hon67, here are the answer:

First of all, put a listctr in the dialog temaplate with ResourceEditor, and set onwer data in the 'more styles' tab.

(note from MS: Note Dynamically switching to and from the LVS_OWNERDATA style is not supported.)

Bind the resource with a CListCtrl using ClassWizard.

And all other is equal.

bye,

Hi pau_serra,

As I am using professional version of VC++5.0, there is no this option (LVS_OWNERDATA) at the more styles property page of the listview.

Is this mean that I cannot build a virtual listview in placing a listctrl from the resource editor?

Thanks!!!

Try this:

In the .rc file, search for the list control, may look like this:

CONTROL "List1",IDC_LISTCTRL,"SysListView32", WS_BORDER | WS_TABSTOP,20,20,200,65

and set LVS_OWNERDATA manually:

CONTROL "List1",IDC_LISTCTRL,"SysListView32", LVS_OWNERDATA | WS_BORDER | WS_TABSTOP,20,20,200,65

Bye!
