TreeView with items that have nodes icons and without icons

Question

I have a TreeView control in a Windows C++ application that has an ImageList set.
I am trying to insert an node that does not have icon (without TVIF_IMAGE flag) but the icon is still displayed.

    TVINSERTSTRUCT tvis = { 0 };
    tvis.hParent = hParent;
    tvis.hInsertAfter = hInsertAfter;
    tvis.item.mask = TVIF_TEXT;
    tvis.item.pszText = (LPTSTR) lpszItem;
    tvis.item.iImage = 0;
    tvis.item.iSelectedImage = 0;
    tvis.item.state = nState;
    tvis.item.stateMask = nStateMask;
    tvis.item.lParam = lParam;
    ::SendMessage(m_hWnd, TVM_INSERTITEM, 0, (LPARAM)&tvis);

Is that possible/ supported ?

I think your question is a better candidate for MFC and Visual C++ tags. — macroland, Feb 14 '14 at 09:30

The thing is you are inserting an item with [default] image 0. You not only need -1, but you also need TVIF_IMAGE:

    tvis.item.mask = TVIF_TEXT | TVIF_IMAGE;
    tvis.item.iImage = -1;

Here is the effect of this change compared you your snippet (source code):

Try setting the image flag to -1 rather than 0;
