BAGIS ESRI addin (.esriaddin) - ftp://basins.geog.pdx.edu/BAGIS/BAGIS_addins/
BAGIS (V2) was developed as an esriAddIn for the ArcMap using the VB .NET framework. A .NET esriAddIn allows developers to access the full capacity of ArcObjects and at the same time allow users to manage the add-in more freely. No administrator privileges are required to install esriAddIn files onto ArcMap. The add-in environment is available only in ArcGIS 10 or later.
BAGIS (V1) was developed in the ArcMap Visual Basic for Applications (VBA) environment. VBA allows full access to ArcObjects, the core computational module and building blocks of ArcGIS, and provides a flexible graphic user interface (GUI) customization capability. The current version (Ver 1) was developed and fully tested on ArcGIS versions 9.X and 10. To use BAGIS, the computer system must have the following software packages installed:
ArcMap 9.X or later with Spatial Analyst extension and VBA capability (Please note that there are different BAGIS files for ArcGIS 9.x and 10)
Microsoft Excel 2007 or later
Notes on ArcGIS VBA deprecation plan
ESRI is phasing out the VBA scripting environment in ArcGIS products. Starting in 10.X, to use VBA, users are required to request VBA license separately from the licenses for other ArcGIS extensions. In 10.1, the ArcGIS Desktop setup does not have the option to install the VBA Compatibility program. Users must install it using the setup program that comes with the ArcGIS Desktop media. The VBA version of BAGIS will not be supported and maintained beyond ArcGIS 10.1. Please use the ESRI Add-In version if there is a VBA compatibility issue on your ArcGIS products.
