I’ve gotten a bunch of requests for sample code to show how to use VBParser, and I have to apologize for not providing that off the bat. It came down to a choice between releasing the library as-is or taking some extra time to put together some samples and then releasing it, and I ended up deciding it was better to just get it out there. I’m planning to work on some simple samples and adding them to the workspace, or others can feel free to join the workspace and do so. [07/12/2014: The sources are now on GitHub.] I realize that it can be a bit difficult to figure out where to start!
I did get trackback from the overflow blog pointing to a sample application that he wrote to explore parse trees, so that might function in a pinch (disclaimer: I haven’t looked at the sample code, so I have no idea how comprehensible it is).
