Complete Guide to the VisualFiles Script Editor The VisualFiles Script Editor is the core environment where developers design, build, and maintain automation logic within the LexisNexis VisualFiles case management system. Whether you are automating document production, managing database updates, or creating complex workflows, mastering the Script Editor is essential for maximizing system efficiency. This guide covers everything from basic interface navigation to advanced scripting practices. 1. Understanding the VisualFiles Scripting Language
VisualFiles utilizes a proprietary scripting language that shares similarities with basic structured programming languages like BASIC or VBA. It is designed specifically to interact with the underlying VisualFiles database, case structures, and user interface elements.
Procedural Execution: Scripts run from top to bottom, utilizing standard control structures like IF…THEN…ELSE, WHILE loops, and FOR loops.
Case Context Aware: The language natively understands the concept of the “current case,” allowing you to reference case data fields directly without complex database queries.
Variable Scoping: Variables can be declared locally within a specific script or globally across the session to pass data between different system components. 2. Navigating the Script Editor Interface
The Script Editor interface is designed to streamline the coding process by putting database fields, system commands, and debugging tools within easy reach. Code Canvas
The main text area where you write and edit your script logic. It features customizable font scaling and layout configurations to suit your development workspace preferences. The Object Browser & Sidebar
Located alongside the main canvas, this panel allows you to browse and double-click to insert:
Database Fields: Search for history, client, matter, or custom user-defined fields.
System Commands: A categorized list of built-in commands (e.g., file handling, date manipulation, string formatting).
System Variables: Pre-defined variables maintained by VisualFiles, such as the current user ID, today’s date, or the active case reference. Toolbars and Status Bar
Quick-access buttons allow you to compile scripts, search for text strings, look up command definitions, and view syntax check results. The status bar at the bottom provides real-time information on your cursor’s line and column position. 3. Essential Syntax and Code Structure
A well-structured VisualFiles script ensures readability and easier long-term maintenance. Variable Declaration
Variables must be explicitly declared before they are used. Common data types include STRING, NUMBER, DATE, and BOOLEAN.
LOCAL STRING lsClientName LOCAL NUMBER lnTotalDue LOCAL DATE ldReminderDate Use code with caution. Accessing Case Data
To pull data directly from the active case record, use the field codes defined in your system database schema.
FETCH “C-NAME” INTO lsClientName IF lsClientName = “” THEN DISPLAY “Error: Client name is missing from this case.” ENDIF Use code with caution. Writing Comments
Always document your code. Use a single quote or specific comment markers to leave notes for yourself or other developers.
’ This section calculates the limitation date based on the accident date ldReminderDate = ldAccidentDate + 1095 ‘ Adds 3 years in days Use code with caution. 4. Key Functions and Commands
VisualFiles scripts gain their power through built-in commands that bridge the gap between user action and database automation. UI Interaction Commands
DISPLAY: Pops up a basic alert message or confirmation box to the end-user.
INPUT: Prompts the user to enter a specific piece of information mid-script.
DIALOG: Launches custom user-defined screens to capture multiple data points seamlessly. Document and Workflow Automation
RUNWORD: Triggers Microsoft Word to generate a specific document template using data merged from the current case.
CREATEHISTORY: Automatically logs an audit entry, note, or completed action into the case history timeline.
TASK: Creates, assigns, or completes diary actions and reminders for fee earners. 5. Compilation, Syntax Checking, and Debugging
Writing code is only half the battle; ensuring it runs without errors is critical to system stability. The Compiler
Before a script can be deployed or linked to a workflow button, it must be compiled within the editor. Clicking the Compile button translates your text code into executable instructions. Syntax Checking
If the compiler encounters an error, it will halt execution and display a list of issues in the output window. Double-clicking an error message automatically jumps your cursor to the problematic line of code. Common compilation errors include: Mismatched IF and ENDIF statements.
Referencing an undeclared variable or an invalid database field code.
Type mismatches (e.g., attempting to save text into a NUMBER variable). Debugging Strategies
While the native environment lacks a step-through debugger found in heavier IDEs, you can successfully debug logic by:
Inserting strategic DISPLAY statements to track variable values at specific execution milestones.
Utilizing specialized system logging commands to output data states to an external text file.
Testing scripts extensively in a dedicated development or “UAT” environment before moving them to production. 6. Best Practices for VisualFiles Developers
Adhering to these industry standards ensures your code remains performant and clean.
Use Consistent Naming Conventions: Prefix your variables to quickly identify their type and scope (e.g., ls for local string, gn for global number).
Keep Scripts Modular: Instead of writing a single, massive script that handles an entire workflow, break your logic down into smaller, reusable sub-scripts. Use the call commands to chain them together.
Validate Data Upfront: Always check that mandatory case fields contain data before running document production or financial calculations to prevent mid-workflow runtime failures.
Optimize Database Loops: When searching or looping through history records, use highly specific filters to minimize system overhead and keep user load times crisp. 7. Advanced Scripting Horizons
Once you master the foundational elements of the Script Editor, you can explore advanced automation capabilities:
COM/OLE Automation: Control external applications like Microsoft Excel or Outlook directly from your script to generate custom spreadsheets or parse emails.
API Integration: Utilize web services and external DLL calls within your scripts to pass data between VisualFiles and third-party software tools, portal environments, or search providers. Proactively Proceed
