It was mentioned earlier so here it is, the tutorial for importing scripts and controls in to ARC project.

It is assumed you have already downloaded or saved the project with the scripts or controls.

First we will start with a new project and remove the tutorial, help etc. controls that we don't need.
Then click on Merge



Select the file which contains the scripts or controls you want to import in to ARC and click OK



Next select all of the controls you wish to import by ticking the check box to the left of the control



Click OK



Voila, the controls or scripts have been added to the project



Check the script to make sure it has worked (not really required)



Adding to an existing project is just the same.

Open up the existing project and click on Merge



Select the project with the controls or scripts you want to import and click OK



Select the controls you want to import by ticking the checkbox on the left and click OK



Voila, the controls or scripts have been added to the project



Check the script to make sure it has worked (not really required)




It really is that easy
