IXRApplication::CreateHostFromXaml (Windows Embedded CE 6.0)

1/6/2010

This method parses the source XAML, generates an element tree, and instantiates a visual host that hosts the element tree so that an application can access or modify the elements in that tree.

Syntax

virtual HRESULT STDMETHODCALLTYPE  CreateHostFromXaml(
    XRXamlSource*         pSource,
    XRWindowCreateParams* pCreateParams,
    IXRVisualHost**       ppHost
) = 0;

Parameters

  • pSource
    [in] Pointer to an XRXamlSource structure that contains information that represents the source of the XAML markup.
  • pCreateParams
    [in] Pointer to an XRWindowCreateParams structure that includes parameters that are used to create the host window. This parameter is optional.
  • ppHost
    [out] Pointer to the newly created IXRVisualHost host object that hosts the generated element tree in a window.

Return Value

Returns an HRESULT that indicates success or failure.

When a XAML parser error occurs, this method can also return one of the following error messages:

Error message Description

XR_E_PARSER_MISSING_DEFAULT_NAMESPACE

Remarks

This method assists in integrating a Silverlight application together with the UI controls and UI resources defined in XAML.

If you want to create a visual host and already have an element tree, call IXRApplication::CreateHostFromElementTree instead of this method.

If you want to create an element tree only, call IXRApplication::ParseXaml instead of this method.

Note

Boolean data types defined in the source XAML file being parsed are case-sensitive and must be in the correct case. For example, "True" and "False."

.NET Framework Equivalent

None.
