Retrieves DISPID_AMBIENT_APPEARANCE, the current appearance setting for the control: 0 for flat and 1 for 3D.
HRESULT GetAmbientAppearance(
short& nAppearance
);
Parameters
- nAppearance
The property DISPID_AMBIENT_APPEARANCE.
Return Value
One of the standard HRESULT values.
Example
HRESULT OnDraw(ATL_DRAWINFO& di)
{
short nAppearance;
RECT& rc = *(RECT*)di.prcBounds;
// draw 3D border if AmbientAppearance is not supported or is set to 1
HRESULT hr = GetAmbientAppearance(nAppearance);
if (hr != S_OK || nAppearance==1)
{
DrawEdge(di.hdcDraw, &rc, EDGE_SUNKEN, BF_RECT);
}
else
{
Rectangle(di.hdcDraw, rc.left, rc.top, rc.right, rc.bottom);
}
SetTextAlign(di.hdcDraw, TA_CENTER|TA_BASELINE);
LPCTSTR pszText = _T("ATL 8.0 : MyControl");
// For security reasons, we recommend that you use the lstrlen function
// with caution. Here, we can guarantee that pszText is NULL terminated,
// and therefore it is safe to use this function.
TextOut(di.hdcDraw,
(rc.left + rc.right) / 2,
(rc.top + rc.bottom) / 2,
pszText,
lstrlen(pszText));
return S_OK;
}
