Unfortunately, there are situations where the application hangs during document saving and ceases to respond. This feature allows you to gracefully cancel long-running operations, such as saving large or complex PDF documents, preventing application freezes, and improving responsiveness. You’ll find the relevant information to integrate this functionality into your applications. Note that this approach ensures that your application remains responsive even during resource-intensive operations.
Let us highlight that the implementation involves several key steps:
InterruptMonitor Creation: Instantiate an InterruptMonitor object. This object acts as a signal for thread interruption.
ThreadLocalInstance Assignment: Before initiating the long-running Aspose.PDF operation, assign the InterruptMonitor instance to InterruptMonitor.ThreadLocalInstance for the current thread. This links the monitor to the thread.
Thread Execution: Execute the code containing the Aspose.PDF operation (e.g., Document.Save()) within a separate thread.
Interruption Signal: At a suitable point (e.g., after a timeout or user action), call monitor.Interrupt(). This signals the thread to terminate.
Exception Handling: The Document.Save() method throws an OperationCanceledException if interrupted. Handle this exception using a try-catch block. Remember that proper exception handling is crucial for application stability.
The following code snippet shows you how to use InterruptMonitor in PDF processing.
