Runtime Execution

The key concept to be aware of regarding the execution of the tasks and expressions defined in the Script Module is that they execute on the server computer.

Only the CodeBehind of the displays is executed on each client computer. The script classes can be consumed by both server and client stations.

Current solutions are prioritizing user interfaces that are portable, meaning the exact same drawing and display configuration can run as a WPF Windows Rich Client or as a web HTML5 page inside a browser. If you intend to run the graphical interface only on WPF Windows and not on web pages, it is possible to enable this in Solution / Settings to allow tasks and expressions to run on the client side.

For complex solutions or very large solutions, it's useful to get a deeper understanding of the Module execution process. Read more at Script Engine (Reference) if that is your case.

Configuration Workflow

Runtime Architecture

Execution Context

Default Configuration:

• Server-side: Tasks and expressions run on TServer.exe
• Client-side: Only Display Code Behind executes locally
• Script Classes: Available to both server and client

Web Compatibility:

• Client-side tasks disabled by default for HTML5 support
• Enable in Solution → Settings for WPF-only deployments

Script Namespace

Access script objects at runtime:

csharp

// Access Script Classes
var result = @Script.Class.ClassName.Method();

// Monitor Script Tasks
int count = @Script.Task.TaskName.ExecutionCount;
TimeSpan cpu = @Script.Task.TaskName.LastCPUTime;

Performance Considerations

For complex or large solutions requiring optimization: → See [Script Engine (Reference)] for deep technical details

Key Concepts

Script Classes

• Repository of reusable methods
• Automatic static instantiation
• Cross-language support (C#/VB.NET/Python)
• Three types: Methods, MCP Tools, Full Namespace

→ [Script Classes (Reference)]

Script Tasks

• Event or time-triggered execution
• Independent threading model
• Automatic exception protection
• Built-in startup/shutdown tasks

→ [Script Tasks (Reference)]

Script Expressions

• Single-line VB.NET statements
• Automatic change detection
• Ideal for simple calculations
• Reduces need for one-line tasks

→ [Script Expressions (Reference)]

Script References

• External DLL integration
• Framework compatibility management
• Namespace declaration system
• Path macro support

→ [Script References (Reference)]

Code Editor

• Multi-language support
• IntelliSense with solution objects
• Integrated debugging
• Language conversion

→ [Code Editor (Reference)]

Best Practices

Code Organization

• Use Classes for reusable logic
• Use Tasks for complex automation
• Use Expressions for simple calculations
• Name consistently with descriptive identifiers

Performance

• Server-side by default for web compatibility
• Monitor execution via diagnostic properties
• Build before deployment to ensure compilation
• Profile large solutions using Script Engine diagnostics

Development

• Format code for readability
• Handle exceptions even with automatic protection
• Test incrementally with build verification
• Document purpose in descriptions

Library Management

• Use References for external DLLs
• Manage namespaces via declaration dialog
• Version control external dependencies
• Test compatibility with target framework

Troubleshooting

Build Issues

Build Errors:

• Check BuildStatus property
• Review BuildErrors details
• Verify referenced objects exist
• Ensure correct language syntax

Circular Dependencies:

• Review build order
• Temporarily comment references
• Restructure class dependencies

Execution Problems

Tasks Not Running:

• Verify InitialState enabled
• Check trigger configuration
• Review domain settings
• Monitor execution count

Performance Issues:

• Check LastCPUTime metrics
• Review execution frequency
• Optimize synchronization
• Consider pre-loading strategy

Reference Issues

DLL Not Loading:

• Verify .NET framework compatibility
• Check path macros
• Restart after DLL updates
• Review resolved status

Namespace Conflicts:

• Use declaration dialog
• Check default namespaces
• Verify reference order

Debugging

Breakpoints Not Hit:

• Enable debug information
• Attach debugger to process
• Verify code has compiled
• Check execution path

Variable Inspection:

• Use @ prefix for solution objects
• PropertyWatch for real-time values
• Watch window during breaks

Common Issues

Language Conversion

• C# to VB.NET usually succeeds
• VB.NET to C# may need type casting fixes
• One-time migration recommended

Client-Side Limitations

• Disabled by default for web
• Only WPF clients support
• Server-side preferred approach

Incremental Compilation

• Automatic background process
• Cache invalidation on changes
• Full build before production

Script Namesace

The Namespace Script is the entry point for all objects related to the Scripts module.

The Script.Class object lists all configured tables and its runtime properties. The Script.Task object lists all configured database connections and their runtime properties.

Examples:

Script Task Properties

Property

Type

Description

Script.Task.Task1.ExecutionCount

Integer

Script.Task.Task1.LastCPUTime

TimeSpan

The Amount of CPU used the last time the Script Task Task1 was executed.

Best Practices and Recommendations

• Code Formatting:  Use the 'Format' feature of the editor for more readability.
• Naming Convention: Use a coherent and descriptive naming convention for tasks.
• Task Domain: Select the appropriate domain for each task, considering whether the task is more suitable for client-side or server-side execution. Remember, Client-Side Tasks only applicable to RichClients
• Reusable Code: Use reusable code by creating classes that encapsulate functionalities for use in various parts of the project.
• Library Management: Manage libraries and external components effectively to avoid conflicts and compatibility issues.
• Code Consistency: Maintain code consistency by following best practices and coding conventions.
• Build Before Deployment: Always perform a build operation before deploying a project in a production environment to ensure all scripts are correct and up to date.

Troubleshooting and Common Issues

The Scripts module may encounter some issues in its operation. Here are some common issues and their troubleshooting:

• Build Errors and Warnings: Make sure to check the 'BuildStatus' and 'BuildErrors' tabs to identify and address errors and warnings that arise during the build.
• Code Language: If you change the code language in the code editor, confirm that the code has been correctly converted to the selected language.
• Build Order: Ensure that the build order of the classes is set up correctly to avoid circular dependencies or initialization issues.
• Domain Selection: Ensure that the domain is selected correctly (Client or Server) based on the needs of your project.
• Reference Issues: Make sure that all external references are configured correctly and that there are no compatibility issues or conflicts in the Code Editor.
• Code Formatting:  Use the 'Format' feature of the editor for more readability.
• Incremental Compilation Issues: Monitor the incremental compilation process to identify and resolve potential issues that may arise.
• Debugger Setup: Ensure that the debugger setup is correct to allow effective code debugging.
• Breakpoints and Watch Variables: Use breakpoints and watch variables effectively to identify and resolve issues.
