I have two buttons, a play and stop button, where only one is enabled at a time. If I use Office 2007 theme + enable animation and click the play button, the effects blink rapidly as they fade away because the play button disables itself on click and the stop button is then enabled.

I've found the problem here, it was in my custom slider control for the command bars causing extra invalidates.

void CXTPSliderCtrlToolbar::OnPaint(void)
{
    const MSG *msg = GetCurrentMessage();
    if( msg->wParam ) {
        CDC *pDC = CDC::FromHandle((HDC)msg->wParam);
        CRect rect;
        GetClientRect(&rect);

        CTransMemDC memDC(pDC, rect, SLIDER_COLORKEY);

        DefWindowProc(WM_PAINT, (WPARAM)memDC.m_hDC, 0);

        if( GetFocus() == this ) {
            CXTPPaintManager *pPaintMgr = static_cast<CXTPMDIFrameWnd *>(AfxGetMainWnd())->GetCommandBars()->GetPaintManager();
            memDC.Draw3dRect(&rect, pPaintMgr->GetXtremeColor(COLOR_BTNSHADOW), pPaintMgr->GetXtremeColor(COLOR_BTNHIGHLIGHT));
        } else if( (GetStyle() & WS_DISABLED) && m_bkColorKey != 0 ) {
            for( int y = rect.top; y < rect.bottom; y++ ) {
                for( int x = rect.left; x < rect.right; x++ ) {
                    if( (x & 1) == (y & 1) ) {
                        memDC.SetPixel(x, y, m_bkColorKey);
                    }
                }
            }
        }
    } else {
        CPaintDC dc(this);
//        GetParent()->RedrawWindow(NULL, NULL, RDW_INVALIDATE | RDW_UPDATENOW);
        if( pControl ) pControl->RedrawParent(FALSE);
    }
}

Instead of calling RedrawWindow, I had to capture the CXTPControlCustom pointer and call it's RedrawParent().

Now there is still another problem -- Office 2007 theme does NOT call WM_CTLCOLORSTATIC when drawing the slider bars, so the background is a solid blue color and not what SLIDER_COLORKEY needs for my transparent DC to work.

How can I make my custom slider control use transparent background with Office 2007 theme? It worked great with Office 2003 theme before.

Hi,

Check Samples\CommandBars\CommandBarControls sample - it has slider + Ribbon theme.

Unfortunately, no, your CXTPControlSlider() will not work - I need access to SetTickFreq() as well as removing TBS_BOTH and increasing the height to 30px. Also, CXTPControlSlider() looks to be drawn in XP style even using Office 2007 Ribbon skin:

The class I've been using since 9.81 and before works fine still, and is even drawn in the correct Office 2007 style:

If I manually set my key color to RGB(191, 219, 255) to match that background color, it is drawn correctly too:

However, that would NOT draw correctly on other systems or themes with the hard-coded key color. I really need it to somehow obey WM_CTLCOLORSTATIC like it still does if I use Office 2003 theme.

Ok, I've found a solution so I can keep using my custom control. Instead of hooking WM_CTLCOLORSTATIC from CXTPControlCustom-derived class with XTPHookManager, I moved the same code to ON_WM_CTLCOLOR_REFLECT in the CSliderCtrl-derived class and it works for Office 2007 while still working the same for Office 2003 theme.
