Using Scripting Host Console

Introduction |  Quick References |  How Do I ... Topics |  Built-in Tools |  Scripting and Programming

Hpmbcalc Scripting Host Console is a normal dialog box. With the console, you can edit, load, run, and debug your scripts. To display the console, you can choose Run Scripts... item From the Script menu.

Hpmbcalc supports both VBScript and JScript scripting engines. When Hpmbcalc starts, it searches Windows registry entries to determine which scripting engines can be used. If either scripting engine is useless, the script type will be disabled. So, before you can run a script under Hpmbcalc Scripting Host, you need install one of the scripting engines in your system.

With the Input Script box of the console, you can edit your script. You can also load a script file into the box by clicking the Browse... button of the console.

You can set the language that your script uses by selecting the VBScript button or the JScript button of the console.

After you have entered or loaded your script, you can click the Execute button of the console to run it. When a script is being run, its output and error information will be routed to the Script Output box. Your script can invoke object method Output to output any text.

You can click the Terminate button of the console to terminate a running script. It is used to cause current script executing thread to exit and should only be used in the most extreme cases.

To see console options

The following console options exist:

• VBScript: Select here to set VBScript as current script language. When selected, Hpmbcalc Scripting Host will use VBScript scripting engines to execute the scripts in the Input Script box.
  
  
• JScript: Select here to set JScript as current script language. When selected, Hpmbcalc Scripting Host will use JScript scripting engines to execute the scripts in the Input Script box.
  
  
• Input Script: It is the "Input Script" box. When you click the Execute button, the scripts in the box will be executed.
  
  
• Browse...: Click here to browse a script file and load its content into the Input Script box.
  
  
• Script File: Shows the last input script file path.
  
  
• Script Output: Shows the output of the current executing script. The script output and runtime error will be route to the box.
  
  
• Execute Status: Shows the current executing status.
  
  
• Execute Time: Shows the time elapsed since the script was executed.
  
  
• Execute: Click here to execute the script in the Input Script box.

• Exit: Click here to close the console. If a script is being executed, the console couldn't be closed until it has been finished or terminated.
  
  

To write a script

Here are the general guides to write a script for running under Hpmbcalc Scripting Host:

1. Examine the script languages that can be used in your system. If both VBScript and JScript are available, choose the one you prefer.
2. Choose your favorite text editor to create your script, or enter script to the Input Script box.
3. Use any valid language-dependent code to write your script.
4. Optionally, use Hpmbmath as object name to invoke Hpmbmath object methods.
5. Optionally, invoke Hpmbmath.Output method to output any text to the Script Output box.

The following JScript code checks the primality of argument strHex for 4 times using Fermat Primality Test.
