Put a bitmap in a toolbars background

Does anyone know how to put a bitmap in a toolbar's background?
Thanks

Introduction
The proposed class is based on Daniel Godson's: Generating inactive/disabled images for toolbar. I have fixed some errors in the original code. But there are still some shortcomings left:

the function to load bitmap from the file and display it is not implemented
the size of buttons on the toolbar is 24×24, I haven't give an interface to change it.
Using the code
Just 2 places you need to edit for your own use.

First is,

Code:

---

<PRE id=pre0 style="MARGIN-TOP: 0px">int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
  if (CFrameWnd::OnCreate(lpCreateStruct) == -1)
    return -1;
 
  if (!m_wndToolBar.CreateEx(this,
    TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP
    | CBRS_GRIPPER | CBRS_TOOLTIPS |
    CBRS_FLYBY | CBRS_SIZE_DYNAMIC) ||
    !m_wndToolBar.LoadToolBar(IDR_MAINFRAME))
  {
    TRACE0("Failed to create toolbar\n");
    return -1;      // fail to create
  }
 
  int *num,i,j=m_wndToolBar.GetToolBarCtrl().GetButtonCount();
  num=new int[j+1];
  memset(num,0,(j+1)*sizeof(int));
  num[0]=j;//button numbers,include the separators.
  for(i=0;i<j;i++)
  {
    if(ID_SEPARATOR == m_wndToolBar.GetItemID( i ))
        num[i+1]=1;
  }//get the button info.zero represent the
  //separators.the info is used to calc
  //the position of the buttons.

  m_wndToolBar.SetFullColorImage(IDR_MAINFRAME_24,
    RGB(255, 0, 255),num); //the first Parameter
    //specify the resource id of button bitmap ,
    //second is the backgroud color of  the toolbar.
   
  if (!m_wndStatusBar.Create(this) ||
    !m_wndStatusBar.SetIndicators(indicators,
    sizeof(indicators)/sizeof(UINT)))
  {
    TRACE0("Failed to create status bar\n");
    return -1;      // fail to create
  }
 
  // TODO: Delete these three lines if
  // you don't want the toolbar to
  //  be dockable
  m_wndToolBar.EnableDocking(CBRS_ALIGN_ANY);
  EnableDocking(CBRS_ALIGN_ANY);
  DockControlBar(&m_wndToolBar);
  delete []num;
  return 0;
}</PRE>

Second is, change the background bitmap here, by resource ID. So you must add the bitmap to your workplace first.

Code:

---

void CMainFrame::OnChangebk()
{
  // TODO: Add your command handler code here
  if(whichbk)
    m_wndToolBar.UpdateBk(IDR_MAINFRAME_24,
          RGB(255, 0, 255) , IDB_BITMAP1);
  else
    m_wndToolBar.UpdateBk(IDR_MAINFRAME_24 ,
      RGB(255, 0, 255) , IDB_BITMAP2);
  whichbk=!whichbk;
}

THAT SHOULD HELP OUT

oh..thanks but..I hate MFC.... :)
