Creating Script Operating with Certain Event

1. Describe the process to be created in C# programming language in a text file, just like an ordinary script.
2. Create a folder with an event name in the scripts folder, and save a file with the extension of .csx in the folder.
   The scripts folder is the one to be opened by clicking in [Open Scripts Folder] on [Scripts] menu in RootPro CAD.
   Any name can be used for a script file name.

   Supplemental
   ▪	To save a script of LayerAdded event in Application class, create a folder named "Application.LayerAdded," and save a script file in the folder. For event names in each class, see RootPro CAD SDK Help.
   ▪	The folder with event name can contain multiple script files. When an event occurs, the script files in the folder will be executed in order.
   ▪	Files must be saved using Unicode (UTF-8) as character codes. In Notepad, modify [Encoding] box on the left of [Save] button on [Save As] dialog box to "UTF-8."

3. Restart RootPro CAD.
   Then the script will be executed when an event occurs.

Event Script Samples

Sample codes for a script to display the message box when a layer is added are shown below.
When creating a folder named "Application.LayerAdded" in the scripts folder and saving a script file under a desired name in the folder, the script will be executed when a layer is added.
The lines starting with "//" are comments, which are not required to input.

// To refer to assemblies other than those in RootPro CAD, describe "
#r "Assembly Name"". #r "System.Windows.Forms" 

// To load another script file, describe as "#load "File Path Name"". 
// Specify a file path name in either an absolute path or a relative path. 
//#load "samplescript.csx" 

// To use a special type without specifying the name space, describe "using NameSpaceName." 
using System.Windows.Forms; 

// To call a property or method in RootPro CAD, use Application global object. 
// To retrieve the current drawing, describe as follows. 
var doc = Application.ActiveDocument; 

// To retrieve a parameter of the event, use EventSender and EventArgs global objects. 
// EventSender and EventArgs are of System.Object type and System.EventArgs type, respectively. 
// To retrieve an event parameter with LayerAdded event of Application class, describe as follows. 
var e = (LayerEventArgs)EventArgs; 

// The message box will be displayed. 
// MessageBox class is that of System.Windows.Forms name space standardly provided by .NET Framework. 
MessageBox.Show(string.Format("Layer "{0}" has been added." , e.Layer.Name));
