Hi,

Don't think Microsoft do this, but guess you have to test it.

Thanks!
 
Btw, is the call to SetItemData(NULL) dangerous or can you assume that WM_PAINT is not sent at this time?

Hi,

 
Call MARKUP_RELEASE(pOldElement) or XTPMarkupReleaseElement();

Consider this:
 
HTREEITEM CMarkupTreeCtrl::AddItem(LPCTSTR lpszItem, int nImage, int nSelectedImage, HTREEITEM hParent/* = TVI_ROOT*/, HTREEITEM hInsertAfter/* = TVI_LAST*/)
{
    CXTPMarkupUIElement* pUIElement = Parse(lpszItem);
    ...
 
 
Now I want to update the text, so I implemented SetItemText. The problem is: how do I free the memory held by the previous CXTPMarkupUIElement object? The destructor is private!
 
----------------------------------------------------------------------------------------
BOOL CMarkupTreeCtrl::SetItemText(HTREEITEM hItem, LPCTSTR lpszItem)
{
    CXTPMarkupUIElement* pOldElement = (CXTPMarkupUIElement*)GetItemData(hItem);
    SetItemData(hItem, NULL); // Not sure if this is necessary?
    // FREE pOldElement??
 
    BOOL retVal = FALSE;
    CXTPMarkupUIElement* pUIElement = Parse(lpszItem);
    if (pUIElement)
        retVal = CXTTreeCtrl::SetItemText(hItem, GetInnerText(pUIElement));
    else
        retVal = CXTTreeCtrl::SetItemText(hItem, lpszItem);
   
    SetItemData(hItem, (DWORD_PTR)pUIElement);
   
    return retVal;
}
