FileSystemWatcher and Polling: The Best Way to Reliable File Change Detection
In local or network file system monitoring, developers need to weigh the advantages and disadvantages of FileSystemWatcher and scheduled polling in terms of reliability and performance.
FileSystemWatcher
FileSystemWatcher monitors file system events and triggers events when files are created, deleted, or modified. It is generally considered a more efficient method of file change detection because it does not require continuous polling. However, its reliability can be a concern.
Polling
The polling method periodically checks for file changes at set intervals. It is a simpler method, but requires more resources and may impact performance, especially if polling intervals are frequent. However, it provides a more powerful method of file change detection.
Reliability
FileSystemWatcher is known to occasionally fail in production and test environments, causing file changes to be missed. Therefore, it is generally recommended to use polling as the primary mechanism for file change detection, with FileSystemWatcher as a secondary means.
Performance
Polling can impact performance if the polling interval is set too frequently. FileSystemWatcher, on the other hand, is generally more lightweight, but may not be reliable enough for critical applications.
Recommended method
To get the best of both worlds, developers should consider combining FileSystemWatcher with periodic polling. FileSystemWatcher quickly identifies file changes, while occasional polling acts as a backup to catch any missed events.
Additionally, a "Refresh" option is provided in the user interface, allowing users to manually trigger file change detection if desired, further improving reliability without impacting performance.

C Interview Questions and Answers: Ace Your Next Technical AssessmentApr 28, 2025 am 12:10 AMC In interviews, smart pointers are the key tools that help manage memory and reduce memory leaks. 1) std::unique_ptr provides exclusive ownership to ensure that resources are automatically released. 2) std::shared_ptr is used for shared ownership and is suitable for multi-reference scenarios. 3) std::weak_ptr can avoid circular references and ensure secure resource management.
The Future of C : Adaptations and InnovationsApr 27, 2025 am 12:25 AMThe future of C will focus on parallel computing, security, modularization and AI/machine learning: 1) Parallel computing will be enhanced through features such as coroutines; 2) Security will be improved through stricter type checking and memory management mechanisms; 3) Modulation will simplify code organization and compilation; 4) AI and machine learning will prompt C to adapt to new needs, such as numerical computing and GPU programming support.
The Longevity of C : Examining Its Current StatusApr 26, 2025 am 12:02 AMC is still important in modern programming because of its efficient, flexible and powerful nature. 1)C supports object-oriented programming, suitable for system programming, game development and embedded systems. 2) Polymorphism is the highlight of C, allowing the call to derived class methods through base class pointers or references to enhance the flexibility and scalability of the code.
C# vs. C Performance: Benchmarking and ConsiderationsApr 25, 2025 am 12:25 AMThe performance differences between C# and C are mainly reflected in execution speed and resource management: 1) C usually performs better in numerical calculations and string operations because it is closer to hardware and has no additional overhead such as garbage collection; 2) C# is more concise in multi-threaded programming, but its performance is slightly inferior to C; 3) Which language to choose should be determined based on project requirements and team technology stack.

C in the Modern World: Applications and IndustriesApr 23, 2025 am 12:10 AMC is widely used and important in the modern world. 1) In game development, C is widely used for its high performance and polymorphism, such as UnrealEngine and Unity. 2) In financial trading systems, C's low latency and high throughput make it the first choice, suitable for high-frequency trading and real-time data analysis.
C XML Libraries: Comparing and Contrasting OptionsApr 22, 2025 am 12:05 AMThere are four commonly used XML libraries in C: TinyXML-2, PugiXML, Xerces-C, and RapidXML. 1.TinyXML-2 is suitable for environments with limited resources, lightweight but limited functions. 2. PugiXML is fast and supports XPath query, suitable for complex XML structures. 3.Xerces-C is powerful, supports DOM and SAX resolution, and is suitable for complex processing. 4. RapidXML focuses on performance and parses extremely fast, but does not support XPath queries.
C and XML: Exploring the Relationship and SupportApr 21, 2025 am 12:02 AMC interacts with XML through third-party libraries (such as TinyXML, Pugixml, Xerces-C). 1) Use the library to parse XML files and convert them into C-processable data structures. 2) When generating XML, convert the C data structure to XML format. 3) In practical applications, XML is often used for configuration files and data exchange to improve development efficiency.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
