The Wisej.NET Timer component provides client-side timing functionality, raising a Tick event after the specified Interval in milliseconds has elapsed. Declare Timer objects at the class level to maintain scope throughout their needed lifetime.

Features

Interval Processing

Configure the Timer for regular processing by:

1. Setting the Interval property (in milliseconds)

2. Handling the Tick event for periodic operations

JavaScript Widget

Wisej.NET provides additional components for specialized functionality like data binding, performance monitoring, messaging, and timing operations. These components enhance applications with system integration and utility features beyond standard UI controls.

The Wisej.NET MessageQueue component wraps Windows Message Queuing technology, enabling communication between applications across heterogeneous networks and systems, even when temporarily offline. Applications can send, receive, or peek (read without removing) messages from queues.

Features

Queue Operations

The MessageQueue class provides methods for queue interaction:

• Send(Object): Send messages to the queue

• Peek: Read messages without removal

• Receive: Retrieve and remove messages

Queue Management

Create new queues or connect to existing ones:

1. Specify a path in the constructor to connect to existing queues

2. Create new queues on the server

3. Configure properties like Category and Label after association

The Wisej.NET PerformanceCounter component enables reading predefined or custom performance counters and publishing data to custom counters through Windows Performance Monitor.

The Wisej.NET EventLog component enables interaction with Windows event logs, which record important software and hardware events. Use it to read existing logs, write entries, manage event sources, and respond to log entries.

Features

Log Management

Access and manage event logs through static EventLog members:

• List available logs

• Create or delete logs

• Create or delete event sources

• Check source existence on a computer

Default Logs

Windows provides three default event logs:

• Application: General application events

• System: Windows system events

• Security: Security-related events (read-only)

Additional logs may be available from installed applications and services like Active Directory.

The Wisej.NET DataSet component provides an in-memory cache of data retrieved from a data source, serving as a key component of the ADO.NET architecture. A DataSet contains a collection of DataTable objects that can be related through DataRelation objects. Data integrity is maintained using UniqueConstraint and ForeignKeyConstraint objects.

Features

Table Management

The DataTableCollection, accessed through the Tables property, contains the data tables. Table names are conditionally case-sensitive - if "mydatatable" exists but "Mydatatable" doesn't, searches become case-insensitive.

Data Relations

The DataRelationCollection enables navigation through table hierarchies, establishing relationships between tables in the DataSet.

XML Integration

The DataSet supports XML operations for data and schema:

• WriteXmlSchema: Save schema as XML

• WriteXml: Save both schema and data

• ReadXml: Load XML documents containing schema and data

The Wisej.NET BindingSource component simplifies data binding by providing currency management, change notification, and intermediary services between controls and data sources. Connect to data through the DataSource property, optionally specifying a DataMember for complex scenarios.

Features

Data Access

Access underlying data through:

• Current: Get or modify the current item

• List: Access the complete data collection

Data Operations

Manage data with methods like:

• RemoveCurrent: Delete current item

• EndEdit: Commit changes

• CancelEdit: Discard changes

Event Customization

Customize behavior through events:

• CurrentItemChanged: React to current item updates

• DataSourceChanged: Handle data source modifications

Navigation Integration

Works seamlessly with the control through its BindingNavigator.BindingSource property for VCR-style data navigation.

Value Refresh

The RefreshValueOnChange property enables automatic source property updates when data-bound values change.

The Wisej.NET BindingNavigator provides standardized data navigation and manipulation. Typically paired with a BindingSource control through the BindingSource property, it enables intuitive record navigation and interaction.

Features

Default Interface

The BindingNavigator includes ToolStrip elements for common data operations:

• Navigation buttons (First, Previous, Next, Last)

• Position and count indicators

• Data manipulation buttons (Add, Delete)

Control-Source Mapping

When bound to a BindingSource, UI controls map directly to source functionality:

Customization

All contained controls support customization while maintaining the standard navigation interface.
