To use the filter interfaces within a Visual Basic 6.0 project you have to import the typelibrary from the filter into the project.
Call the References command from the Project menu.
In the References dialog select the type library from the filter and press OK.
Now you can use the filter interfaces like any other types within Visual Basic.
The VisualBasic folder in the installation path from the MontiVision Workbench contains the MVDefinitions.bas modul file. This file contains a lot of definitions, like enums ect., to work with MontiVision Imaging Filter. Include the modul file into your application projects.
