View 4 RepliesOne of the Projects in my VB.NET Solution seemed unwilling to let me write XML Documentation in my code. When tapping ''' on the line directly above a method declaration, nothing would happen. The project consisted of modules and classes only(no forms), so I initially thought that had something to do with it.
Later I found that under project properties and the Compile tab, the "Generate XML documentation file" checkbox was left unchecked. Checking this instantly allowed me to place the comments normally. After doing some testing, I also found that Creating an Empty project leaves the checkbox unchecked, while creating a Windows Application automatically checks it.

I would like to make a system of documentation consisting of an html pages that link to code, and vice versa.

I'm looking for an efficient means of extracting an html "fragment" from an html document. My first implementation of this used the Html Agility Pack. This appeared to be a reasonable way to attack this problem, until I started running the extraction on large html documents - performance was very poor for something so trivial (I'm guessing due to the amount of time it was taking to parse the entire document).[code]...
