Using VB.Net 2005...

1) Is there a way to execute a macro code, the same type of code you would find in a tool bar button using the Dot.Net API? I know of the Dwg.SendStringToExecute method but it will only run a command and doesn't except special character codes like the ^M for enter.

2) Is there a way to toggle tool bar buttons either visible or enabled using the Dot.Net API?
