SQL Service Broker
After trying to receive a message from a service broker queue for a while I found that it will not throw an error if your database isn’t setup correctly. After looking in the table where the messages are stored before they are sent to the queue the solution was easily found
The Error
An exception occurred while enqueueing a message in the target queue. Error: 15517, State: 1. Cannot execute as the database principal because the principal "dbo" does not exist, this type of principal cannot be impersonated, or you do not have permission.
Where messages are stored before they are sent to queue, and any exceptions which occurred
select * from sys.transmission_queue
Fix
USE [database_name] ALTER DATABASE [database_name]SET TRUSTWORTHY ON ALTER DATABASE [database_name] SET ENABLE_BROKER WITH ROLLBACK IMMEDIATE ALTER AUTHORIZATION ON DATABASE::[database_name] TO [SA];

Shape Connections
Shapes can now be drawn and connected together. When a shape is connected a line from the centre of the shape will draw to the centre of the connected shape. Moving of shapes redraws the line correctly.
The next step is to change the shape matching method. The current method is to take the points in the line and match the pattern against an algorithm. However this is inflexible and will be changed to a neural network method so that shapes that are slightly off can be matched. This will also allow for the easy creation of new shapes
