Question

I want my tree view control to show an item with a folder icon next to it.
so, 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, this does not add a folder icon next to my subscription label. it works correctly but doesn’t display any image.

Answer 1

instead of using :

bmp.FromHandle(hFolderBitmap);

I had to use :

bmp.Attach(hFolderBitmap);
