Visual studio and visual basic get properties

[Anonymous]

Hi good morning, I need help.  
In school I left an exercise in visual Basic and AutoCAD and need help,
The problem is that I need to do to get the properties to click a wall for example, what is the height, broad and then do things like operations.
The bad is that it's my first time doing this kind of development with AutoCAD, I would greatly appreciate if you help me step by step

sorry, you know what is the route for references?

i have a error

huh... I wonder why. Remove the Autocad references from the right. Then right click on reference tree For 2012 Add: AcObjClassImp 1.0 Type Library AutoCAD 2012 Type Library For 2014 it's a little different. I'll have to share all info tomorrow. Does the exe work for you?

Hello thank you very much for the help it works great I just wanted to ask you one thing, when I migrate it to Visual Basic Error muetro what you image, you define with this line and the "Out"

Maybe this will help. See: http://msdn.microsoft.com/en-us/library/ee332485.aspx

GetEntity will set the 'ent' as the entity selected.
So, instead of setting ent like normal (example: AcadObject ent = cad.ActiveDocument.Utility... etc)

It must be set as shown in the image.

the great thing about visual studios is it will give you the required arguements
