CTreeCtrl icons without 256 colours

[Rui Oliveira]

I am using a tree from CTreeCtrl.

To create the imagelist I am using a bitmap with 256 colours.

But the icons in my tree only appear with 16 colours.

What is supposed to do to have icons with 256 colours in tree?

This is my code:
-------------------------------------------------------------
CTreeCtrl& lcl_tree = GetTreeCtrl();
CImageList icl_listaImagem ;
icl_listaImagem .Create( IDB_BITMAP_VECT OR_IMAGEM256, 17, 1, RGB(5,255,5) );
lcl_tree.SetIma geList(&icl_lis taImagem, TVSIL_NORMAL);

// Set tree control styles
long style = GetWindowLong(l cl_tree.m_hWnd, GWL_STYLE);
style |= (TVS_HASLINES | TVS_LINESATROOT | TVS_HASBUTTONS |
TVS_SHOWSELALWA YS | TVS_DISABLEDRAG DROP);
SetWindowLong(l cl_tree.m_hWnd, GWL_STYLE,style );

// Insert some items
HTREEITEM lcl_auxItem;
HTREEITEM lcl_vaultItem = lcl_tree.Insert Item("Teste..." , 1, 1 );

-------------------------------------------------------------
