Does the NHD ArcView Toolkit work with ArcView 8?
Many NHD users have asked us about using the NHD ArcView Toolkit in ArcView 8. The current Toolkit works only in ArcView 3.x. As many of you know the development environment for ArcView 3.x is a programming language called Avenue. The Toolkit is written in Avenue with some routines in C++. ESRI has decided not to support the use of Avenue in ArcView 8.x. Consequently, we, like many ArcView users, face a complete rewrite of the Toolkit in order to move its functionality to ArcView 8.x. We are currently in the process of defining an ArcGis8 geodatabase model for NHD. When NHD moves from the current coverage model into the new geodatabase model, all of the NHD tools will need to be redesigned. Therefore, we have decided to postpone the process of porting the Toolkit to ArcView 8.x until we are ready to convert the NHD to geodatabase.
