GUI Issues for ComboBox & Tab Control

Hi,

I have used background image for sample application. I have GUI issue related to ComboBox & Tab Control.

I have applied the Office-2007 Blue style to the application using following method:

XTPSkinManager()->SetApplyOptions(XTPSkinManager()->GetApplyOptions() | xtpSkinApplyFrame | xtpSkinApplyColors | xtpSkinApplyMetrics);
XTPSkinManager()->LoadSkin(m_strStylesPath + _T("Office2007.cjstyles"), _T("NormalBlue.ini"));
XTPSkinManager()->SetAutoApplyNewThreads(TRUE);

ComboBox:
          ComboBox control is not painted well, the drop down items drown as transperent background.

Tab Control:
          Tab control should have transperent background header. Now it showing theme color for blank space.


For to draw transparent background for all controls I have added ON_WM_CTLCOLOR() message.
Please have look code part:

HBRUSH CSkinControlsDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH oHBRUSH = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

int iCtrlId = pWnd->GetDlgCtrlID();
if (iCtrlId == IDC_STATIC )
{
pDC->SetTextColor(RGB(0,0,0));
pDC->SetBkMode(TRANSPARENT);
return (HBRUSH)GetStockObject(HOLLOW_BRUSH);
}

if(iCtrlId == IDC_COMBO_VERTICAL || iCtrlId == IDC_COMBO_HORIZONTAL)
{
pDC->SetBkMode(TRANSPARENT);
return oHBRUSH;
}

if(iCtrlId == IDC_TAB_SAMPLE)
{
pDC->SetTextColor(RGB(0,0,0));
pDC->SetBkMode(TRANSPARENT);
return oHBRUSH;
}

return (HBRUSH)GetStockObject(NULL_BRUSH);
}


Please find attached screen capture. Please let me know if I am missing anything.
