How to use CImageList

I want my tree view control to show an item with a folder icon next to it. therefore, I wrote this piece of code:

HBITMAP hFolderBitmap = (HBITMAP)::LoadImage(AfxGetInstanceHandle(),_T("info.bmp"),IMAGE_BITMAP,20,20,LR_LOADFROMFILE|LR_CREATEDIBSECTION);

if(hFolderBitmap)
{
    cil.Create(20,20,ILC_COLOR32,0,5);

    bmp.FromHandle(hFolderBitmap);
    cil.Add(&bmp,RGB(255,0,255));
}

GetTreeCtrl().SetImageList(&cil,TVSIL_NORMAL);
hrootFolder = GetTreeCtrl().InsertItem(_T("Subscriptions"),0,0,TVI_ROOT);

but that doesn't add the folder icon next to my signature. it works correctly but doesn't display the image.

instead of using:

bmp.FromHandle (hFolderBitmap);



I had to use:

bmp.Attach (hFolderBitmap);

I am using this:



UINT uiBmpId = theApp.m_bHiColorIcons ? 
    IDB_MACROBROWSE_IMGLIST_HQ : IDB_MACROBROWSE_IMGLIST;

CBitmap bmp;
if( !bmp.LoadBitmap( uiBmpId ) )
{
    ASSERT( FALSE );
    return;
}

BITMAP bmpObj;
bmp.GetBitmap (&bmpObj);

UINT nFlags = ILC_MASK;
nFlags |= (theApp.m_bHiColorIcons) ? ILC_COLOR24 : ILC_COLOR4;

m_imageList.Create( 16, bmpObj.bmHeight, nFlags, 0, 0 );
m_imageList.Add( &bmp, RGB (255, 0, 255) );

GetTreeCtrl().SetImageList (&m_imageList, TVSIL_NORMAL);
