I tried to load an image in treeView but it isn't loaded..

C++

HTREEITEM hItem;
CBitmap m_Bitmap1, m_Bitmap2, m_Bitmap3, m_Bitmap4;

m_Bitmap1.LoadBitmap(IDB_BITMAP2);
//m_Bitmap2.LoadBitmap(IDB_BITMAP9);

CImageList* m_ImageListTree;
m_ImageListTree = new CImageList;

m_ImageListTree->Create(16, 16, ILC_COLOR32, 1, 1);
m_ImageListTree->Add(&m_Bitmap1, RGB(255, 0, 255));
m_treeCtrl.SetImageList(m_ImageListTree, LVSIL_SMALL);

hItem = m_treeCtrl.InsertItem(aDir[i],i,i, TVI_ROOT);

What is aDir and what is the value of i?

You better use the debugger to see whether your m_Bitmap1 has loaded the image and check the return codes. If I remember correctly this MFC code is very picky in image format and size.

Are you getting an hItem back?

I have modified in code. try the following:

HTREEITEM hItem;
CBitmap m_Bitmap1, m_Bitmap2, m_Bitmap3, m_Bitmap4;

m_Bitmap1.LoadBitmap(IDB_BITMAP1);

CImageList* m_ImageListTree;
m_ImageListTree = new CImageList;
m_ImageListTree->Create(IDB_BITMAP1, 16, 16, RGB(255, 255, 255));
m_ImageListTree->Add(&m_Bitmap1, RGB(255, 0, 255));
m_treeCtrl.SetImageList(m_ImageListTree, LVSIL_SMALL);
