- ActiveX Scripting Documentation (for Visual IRC '97 1.00 and above) - Revision 2
- ================================================================================
-
- ViRC '97 1.00rc2 and above support ActiveX scripting, which means that you can
- mix VBScript and JavaScript code within your ViRCScript code. This is an
- extremely powerful feature seen in no other IRC client which allows you to use
- multiple scripting languages at once to achieve the best result.
-
- 1.00rc3 and above allow additional Active Scripting language DLLs to be
- installed via the Client setup/Active scripting page. This effectively allows
- any language to be used, not just VBScript and JavaScript.
-
- This document is not intended as an introduction to the VBScript or JavaScript
- scripting languages. Books intended for this purpose can be purchased from your
- favourite computer bookshop.
-
- ActiveX scripting is controlled by the new LANGUAGE statement.
-
- LANGUAGE statement
- ------------------
-
- Usage: Language VBScript
- ...
- EndLanguage
-
- Language JavaScript
- ...
- EndLanguage
-
- In the ... code block, VBScript or JavaScript code can be inserted as desired.
-
- There is, of course, a mechanism provided for VBScript and JavaScript code to
- examine ViRCScript variables, execute ViRCScript statements, and so forth. This
- is accomplished through the special ViRCScript object which is available to
- VBScript and JavaScript code. The methods it supports are detailed below.
-
- ViRCScript.GetVar method
- ------------------------
-
- Usage (VBScript): x = ViRCScript.GetVar("$variable")
- Usage (JavaScript): x = ViRCScript.GetVar("$variable");
-
- Returns the contents of the ViRCScript variable $variable.
-
- ViRCScript.SetVar method
- ------------------------
-
- Usage (VBScript): ViRCScript.SetVar "$variable", "value"
- Usage (JavaScript): ViRCScript.SetVar("$variable", "value");
-
- Sets the value of the ViRCScript variable $variable to value.
-
- ViRCScript.Parse method
- -----------------------
-
- Usage (VBScript): x = ViRCScript.Parse("expression")
- Usage (JavaScript): x = ViRCScript.Parse("expression");
-
- Fully evaluates expression, which can contain ViRCScript variables and
- functions, and returns the evaluated expression.
-
- ViRCScript.Execute method
- -------------------------
-
- Usage (VBScript): ViRCScript.Execute "command"
- Usage (JavaScript): ViRCScript.Execute("command");
-
- Executes the ViRCScript command command. This allows VBScript and JavaScript
- code to execute regular ViRCScript statements. For example, this code will
- sum all the numbers from 1 to 1000 and display the result in a standard
- ViRCScript message box:
-
- Language JavaScript
- var j = 0;
- for (i = 1; i <= 1000; i++)
- j += i;
- ViRCScript.Execute("MessageBox " + j);
- EndLanguage
-
- The same code could be expressed in VBScript as:
-
- Language VBScript
- j = 0
- For i = 1 To 1000
- j = j + i
- Next
- ViRCScript.Execute "MessageBox " & j
- EndLanguage
-
- It could be coded in ViRCScript as the following (note the similarily to the
- JavaScript code):
-
- @ $j = 0
- for (@ $i = 1; $i <= 1000; $i++)
- $j += $i
- endfor
- MessageBox $j
