chm file works fine. Now we want to switch to online document.
I tried replacing chm with URL, does not work
[ExcelFunction(Description = "My function desc", Category = "MyAddIn", HelpTopic = "https://www.google.com/"]
public static object MyUDF(string param1)
When I select MyAddIn category, select MyUDF from "insert function" dialog, click "Help on this function", it says "help not found"
so how to use URL instead of chm for Excel function?
