I want to copy this code for a tool that runs like a geo-processing tool for water flow.
I'm moving from ArcMap VBA Editor to Pro SDK from MS Visual Studio using ArcGIS Pro based on these ESRI articles:
ArcGIS Desktop and VBA Moving Forward (esri.com)
Recycling VBA (esri.com)
I'm a little unsure how to do this. I have some screen shots of the code and my progress. Thank you!
