Prevent listview column resize

Hey all win32 programmers

Ive recently been coding a program using the listview control and cannot get the columns to stay a fixed size.

Here is my code so far:

Code:

---

case WM_NOTIFY:
{
        LPNMLISTVIEW pNotify = (LPNMLISTVIEW)lParam;
        if (wParam == IDC_LISTVIEW)
        {
                if(pNotify->hdr.code==HDN_BEGINTRACKW || pNotify->hdr.code==HDN_BEGINTRACKA)
                {
                        return TRUE;
                }
        }
}

---

Does anyone know how to fix this?

Thx in advance.

HDN_BEGINTRACK
lParam is an LPNMHEADER, so try:

Code:

---

if(((LPNMHEADER)lParam)->hdr.code == HDN_BEGINTRACK)

---

I suspect that the header control notifications are sent to the list-view rather than the list-view parent.

You could get the header control using ListView_GetHeader and then remove the HDS_DRAGDROP style using SetWindowLong.
