Toolbar - Depth Color for Icons - visual-c++

Question

I wanna make a large toolbar with support of icons with more colors depth than default in Visual Studio. I am using Visual Studio 2005 and the Toolbar is on a CDialog.
I used the Code found : here
but did not work.
int CSalariesForm::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CDialog::OnCreate(lpCreateStruct) == -1)
return -1;
HBITMAP hBitmap = (HBITMAP) ::LoadImage(AfxGetInstanceHandle(),
MAKEINTRESOURCE(IDR_MAINFRAME1), IMAGE_BITMAP,
0,0, LR_CREATEDIBSECTION | LR_LOADMAP3DCOLORS);
CBitmap bm;
bm.Attach(hBitmap);
CImageList m_imagelist;
m_imagelist.Create(20, 20, ILC_COLOR8, 4, 4);
m_imagelist.Add(&bm, (CBitmap*) NULL);
cToolBar.Create(this);
cToolBar.GetToolBarCtrl().SetImageList(&m_imagelist);
cToolBar.ShowWindow(SW_SHOW);
cToolBar.SetBarStyle(CBRS_TOOLTIPS | CBRS_FLOATING | CBRS_ALIGN_TOP | CBRS_FLYBY);
RepositionBars(AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0);
return 0;
}
And when I call the dialog there is no Toolbar shown. What is wong with the code?
Thank You

Assigning an image list to a toolbar does not create any toolbar buttons. Also your image list should be a class member, not a local variable.
// header file
private:
CImageList m_imagelist;
CToolBar m_toolbar;
// source file
enum { width = 20, height = 20 }; // width and height of one button image
m_toolbar.Create(this);
// create the image list
m_imagelist.Attach(
ImageList_LoadImage(
AfxGetInstanceHandle(), MAKEINTRESOURCE(IDB_BITMAP1), width, 4,
CLR_DEFAULT, IMAGE_BITMAP, LR_CREATEDIBSECTION | LR_LOADTRANSPARENT )
);
// set button and image sizes (copied from CToolBar::LoadToolBar)
m_toolbar.SetSizes(CSize(width+7,height+7), CSize(width,height));
// set image list
m_toolbar.GetToolBarCtrl().SetImageList(&m_imagelist);
// define command ids for each button
const UINT cmdIds[] = {
IDOK,
0, // separator
IDCANCEL,
};
// assign ids to the toolbar
m_toolbar.SetButtons(cmdIds, sizeof(cmdIds)/sizeof(UINT));
RepositionBars(AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0);
IDB_BITMAP1 is a 40x20 24bit color bitmap (two 20x20 buttons). If you need more control over the creation of the buttons, you can use CToolBarCtrl::SetButtons() instead. Refer to ImageList_LoadImage for more details on loading the image list.
