The Script Management interface provides methods for getting script information, launching other scripts and programs, and displaying informational messages and prompts to users. The methods are organized into the following sections:
The Script Information and Helper methods get information about a script (name, ID, and execution context) and provide general script helping functions such as creating a new unique ID for use in the script, generating trace messages for the script, and pausing the script for a specified amount of time.
|
|
Description: |
Gets the name of the script. The name is derived from the Scripting policy name. |
|
|
Description: |
Gets the script identifier. The identifier is derived from the Scripting policy ID. |
|
|
Description: |
Gets the context (user or system) in which the script is running. |
|
|
Description: |
Generates a unique identifier for use by the script. |
|
|
Description: |
Sends trace messages to the user or service logs (depending on whether the script is running in the user context or system context). Each trace message has its script id concatenated to the message. The trace messages can also be viewed in the Script Tracing dialog of the Endpoint Security Agent About box. |
|
|
Parameters: |
msg — The message string to log. |
|
|
Description: |
Causes the script to sleep for a specified period of time. |
|
|
Parameters: |
millisec — The number of milliseconds the script sleeps before proceeding. The implementation wakes up on a regular interval to check if the script needs to be terminated early due to a policy change or agent restart. Control is returned only after the number of milliseconds has expired. |

The Launch/Execute methods provide ways to launch and execute programs. A launch method runs the program but does not wait for the program to finish and return an exit code. An execute method runs the program and waits for it to finish and return an exit code, or for the execution timeout to expire.
A launched or executed program runs in the same context (user or system) as the script, unless the script overrides the context by passing a new context.
Be aware that some Windows operating systems may not allow GUI applications to display in the system context.
|
|
Description: |
Starts a program in the requested context. The script continues without waiting for the program to return an exit code. |
|
|
Parameters: |
context — Valid inputs are user or system. Leave the parameter empty to run the program in the same context as the script. If the user context is requested and the primary user context is unavailable, an error code is returned and the request is dropped. hide — If true, the command shell used to launch the program is not displayed. If false, the command shell is displayed. command — The command to execute. If the command starts with http: or www., the link is launched using the default web browser. parameters — Parameters to be passed to the command. |
|
|
Returns: |
The following are common return values. Other values are also possible:
|
|
|
Description: |
Starts a program in the requested context. The script pauses until the program returns an exit code. |
|
|
Parameters: |
context — Valid inputs are user or system. Leave the parameter empty to run the program in the same context as the script. If the user context is requested and the primary user context is unavailable, an error code is returned and the request is dropped. hide — If true, the command shell used to execute the program is not displayed. If false, the command shell is displayed. command — The command to execute.

Action.Trace("User: Execute with Timeout, notepad: " & ret)
The Display methods enable a message to be displayed to a user. The methods are valid only if the script is running in a user session.
The displayed message includes an OK button to dismiss the message. You can also set a timeout to automatically dismiss the message. The message does not pause the script; it continues to run while the message displays.
Display messages are intended for providing information to the user. If you need to display a message that requires the user to make a choice (such as OK or Cancel), you should use a message prompt. See Prompt Methods.

A safe array indexes a list of objects. Safe arrays are native to VBScript and provide a way to enumerate all elements in the array. Safe arrays are not native to JScript; they must be converted using the native VBArray function provided by WScript.
Functions that return a safe array value end in Array (for example, EffectivePolicyArray). The followng VBScript and JScript examples use EffectivePolicyArray as a safe array.
Action.Trace(" ******** Array Access ****** ");
var a = new VBArray(Query.EffectivePolicyArray());
ret = a.toArray();
for (var i = 0; i < ret.length; i++) {
var pol = ret[i];
Action.Trace(" ******** Policy Information ********* ");
Action.Trace("ID: " + pol.Id);
Action.Trace("Version: " + pol.Version);
Action.Trace("Name: " + pol.Name);
Action.Trace("Type: " + pol.PolicyType);

Because JScript does not support the native importing of safe arrays, and does not support an array enumerator, ZENworks Endpoint Security Management provides an object called Object Match List to allow for index enumeration of a list to both VBScript and JScript. Functions that return this type of object end in List (for example, EffectivePolicyList). The object provides the following functions and properties for access to the objects in the container.
|
|
Description: |
Returns the number of objects in the container. |
|
|
Description: |
Returns a particular object from the container based on the index given. If the index is outside the count of container, a null/empty object is returned. The order of objects in the container is not guaranteed. |
|
|
Description: |
Returns an object that matches the value provided. If no matches are found in the container, a null/empty object is returned. |
