Debug Error
Hi Shafeer.
From your attached screenshot, it seems you are calling a class named Utils, which probably you are missing in your project.
If you haven't created this class, which I understand also that contains the function SelectSingleElement the error to compile your project will persist.
If I'm not mistaken you took this command from Jeremy Tammik's post
http://thebuildingcoder.typepad.com/blog/2008/10/element-bounding-box.html
If you see at the end of the post, there is a link to get the entire VS Solution, which will include the Utils Class you are missing in this case.
It will be only a matter of adding this to your project to do the right reference to the public functions you are calling in your command.
This is the line I'm telling you to look for.
"I am adding a new version 1.0.0.8 of the complete Visual Studio solution here, including the new CmdBoundingBox class as well as all other commands discussed so far."
Let me know how it goes.
