IXRUIElement::GetCacheMode (Windows Embedded CE 6.0)
1/6/2010
This method retrieves a value that indicates whether this UI element will use bitmap caching and hardware-accelerated graphics when it is displayed at run time.
Syntax
virtual HRESULT STDMETHODCALLTYPE GetCacheMode(
IXRCacheMode** ppCacheMode
) = 0;
Parameters
- ppCacheMode
[out] Address of a pointer that will point to an IXRCacheMode-derived object if this UI element will use bitmap caching and hardware-accelerated graphics at run time.
Return Value
Returns an HRESULT that indicates success or failure.
Remarks
You can use bitmap caching for a UI element if it implements one of the following features:
- Transformations (such as translating, rotating, or stretching)
- Clipping
- Blending
- Resources or child objects that are animation storyboards

To use a specific interface pointer type, you can use the helper template version of this method that Silverlight for Windows Embedded provides. When you supply a derived type, this version automatically supplies a type-safe method that implicitly converts the returned type from a generic interface so you do not have to explicitly call QueryInterface to convert the generic interface into the required object type. For more information, see Type-Safety in Silverlight for Windows Embedded.
.NET Framework Equivalent
None.
