How about GetHeaderCtrl()->ModifyStyle(...);

At least this way you won't have any memory leaks

Hi,

I have a CListCtrl with a subclassed CHeaderCtrl, and I want the
CListCtrl to not show contents while resizing columns. From what I
read, this is controlled by the HDS_FULLDRAG parameter in CHeaderCtrl,
which I never set. So, I tried CHeaderCtrl::ModifyStyle to turn this
off in both the original and subclassed versions, but to no avail.
Here's my code from the OnCreate member of a subclassed CListCtrl:

   CHeaderCtrl* pHeaderCtrl = GetHeaderCtrl();
   pHeaderCtrl->ModifyStyle(0, HDS_FULLDRAG);
   m_pNewHeaderCtrl = new CMyHeaderCtrl();
   m_pNewHeaderCtrl->SubclassDlgItem(pHeaderCtrl->GetDlgCtrlId(),
this);

But that didn't work. So I tried modifying the subclassed one in the
same manner:

   CHeaderCtrl* pHeaderCtrl = GetHeaderCtrl();
   m_pNewHeaderCtrl = new CMyHeaderCtrl();
   m_pNewHeaderCtrl->SubclassDlgItem(pHeaderCtrl->GetDlgCtrlId(),
this);
   m_pNewHeaderCtrl->ModifyStyle(0, HDS_FULLDRAG);

But to no avail either. I tried using ModifyStyleEx, in the same
fashion but that didn't do it either.

Any help is greatly appreciated.

Thanks.
