Microsoft DirectX 9.0


The Filter property retrieves the filter associated with this object.


objFilterInfo.Filter As Unknown


This property takes no parameters.

Return Values

Returns the filter.


The IFilterInfo object is a wrapper for a DirectShow filter, because DirectShow filters expose the IBaseFilter interface, which is not Automation-compatible. This property returns the underlying filter as an IUnknown pointer. There are no methods in the Quartz.dll type library that can take this object as a parameter. It is provided for use with DLLs that take an IBaseFilter parameter. Also, it might be useful if you write your own Automation-compliant COM wrapper object for DirectShow.

This property is read-only.
