GetCustomUI
Called by PresentationHost.exe to get custom progress and error messages from the host, if implemented.
Syntax
HRESULT GetCustomUI( [out] BSTR* pwzProgressAssemblyName, [out] BSTR* pwzProgressClassName, [out] BSTR* pwzErrorAssemblyName, [out] BSTR* pwzErrorClassName );
Parameters
pwzProgressAssemblyName
[out] A pointer to the assembly that contains the host-supplied progress user interface.
pwzProgressClassName
[out] The name of the class that is the host-supplied progress user interface, preferably a XAML file with xref:System.Windows.Controls.Page is its top-level element. This class resides in the assembly that is specified by pwzProgressAssemblyName.
pwzErrorAssemblyName
[out] A pointer to the assembly that contains the host-supplied error user interface.
pwzErrorClassName
[out] The name of the class that is the host-supplied error user interface, preferably a XAML file with xref:System.Windows.Controls.Page is its top-level element. This class resides in the assembly that is specified by pwzErrorAssemblyName.
Property Value/Return Value
HRESULT: Ignored.
Remarks
A host application may have a specific theme that PresentationHost.exe’s default user interfaces may not conform to. If this is the case, the host application can implement GetCustomUI to return progress and error user interfaces to PresentationHost.exe. PresentationHost.exe will always call GetCustomUI before using its default user interfaces.
This function is called once during PresentationHost’s initialization.
