Icons in CXTPToolBar

Hi,

I'm trying to reuse some icons in a toolbar with the following code.

{
    // make the array for the icons
    UINT icons[] = {0, 0, 0, 0, 0, ID_VALUESET_COMMITCHANGES};

    // now set the color icon
    int index = 0;
    // if we have a valuset, get the correct color
    icons[index] = ID_VALUESET_COLOR;
    // set the icons for the toobar
    VERIFY(m_MainToolBar->GetImageManager()->SetIcons(IDB_VALUESET, icons, _countof(icons), CSize(32, 32)) );
    m_MainToolBar->Invalidate();
}

What I'm seeing is that I am always getting the first 2 icons out of IDB_VALUSET which is a .png file. The behavior I desire is to pick icons within that file and set them on particular buttons. m_MainToolBar is a CXTPToolBar.

Is it the case that the specification of icons[] is somehow wrong, or is this just not possible with a CXTPToolBar?

Thanks,

Darin

Thanks.

We have found 2 ways to resolve this problem and would like to know which is the preferred method.  We found empirically that:

1. Since there are 10 images in my .png file, if I change the icon array to have a place for each icon, the code works.

UINT icons[] = {0, 0, 0, 0, 0, ID_VALUESET_COMMITCHANGES, 0, 0, 0, 0};

2. Changing the array to indicate unused icons with -1 makes the icon mapping work

UINT icons[] = {-1, -1, -1, -1, -1, ID_VALUESET_COMMITCHANGES};

Which is preferred? I tend to like number 2 because it doesn't require me to know how many icons are in the png file, just account for which ones I'm using.

Thanks
