Debug assertion failed while Cimage.Save

[330xi]

I have this error in atlimage.h line 1568 while trying to save picture. In release mode everything is "fine" but no new file appears. Here is the code:

    CClientDC dc(this); 
    CDC       dcMem;
    CBitmap   m_bmpBack;

    GetClientRect(&rc);  
    hBmp = LoadImage(NULL,name,IMAGE_BITMAP,0,0,LR_LOADFROMFILE);   
    GetObject ( hBmp, sizeof(bm), &bm );    
    m_bmpBack.Attach(hBmp);



    dcMem.CreateCompatibleDC(&dc);
    hbmpOld = (HBITMAP)dcMem.SelectObject(m_bmpBack);

    //hToSave = (HBITMAP)hBmp;
    //hToSave = (HBITMAP)m_bmpBack;
    //hToSave = (HBITMAP)dcMem.SelectObject(m_bmpBack);
    hToSave = (HBITMAP)dcMem.GetCurrentBitmap(); //I tried each of them, all the same result(

    dc.StretchBlt(rc.left, rc.top, rc.right, rc.bottom,&dcMem, 0, 0, (int)bm.bmWidth, (int)bm.bmHeight, SRCCOPY); 


    CImage myImage;
    if (hToSave!=NULL)
    {
        myImage.Attach(hToSave);
        myImage.Save(L"d:/image3.jpg");
    }
    else
    {
        name = L"d:/backgrnd.bmp";
    }

What I have to add or remove to make this work?

Is the hBmp NULL?

This code was in OnPaint as I remember, and it seems to me, yes, I've added a kind of hBmp = null and m_bmpBack.DeleteObject(); and even myImage.Destroy(); at the beginning and everything works fine now.

But thanks!) your question could give me some clue to the solvation of my problems.
