| Microsoft DirectX 8.1 (C++) |
The Filter property retrieves the filter associated with this object.
Syntax
objFilterInfo.Filter As Unknown
Parameters
This property takes no parameters.
Return Values
Returns the filter.
Remarks
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.
