VS2010在“工具->选项->项目和解决方案->VC++ 目录”的功能已经被否决，不再提供设置。但是每个工程都要在“项目->属性->配置属性->VC++ 目录”中一一设置如OpenCV之类的公共库文件目录是件很麻烦的事，如何解决呢？
1、先打开任意一个VC项目，再打开VS2010的属性管理器（视图->其他窗口->属性管理器）；
opencv配置：
修改环境变量，PATH中添加C:\Program Files\opencv\build\x86\vc10\bin\
在Include Directories中添加
C:\Program Files\opencv\build\include\opencv,
C:\Program Files\opencv\build\include\opencv2,
C:\Program Files\opencv\build\include
在Library Directories中添加
C:\Program Files\opencv\build\x86\vc10\lib
在Linker->Input，Additional Dependencies中添加
opencv_calib3d243d.lib
opencv_contrib243d.lib
opencv_core243d.lib
opencv_features2d243d.lib
opencv_flann243d.lib
opencv_gpu243d.lib
opencv_highgui243d.lib
opencv_imgproc243d.lib
opencv_legacy243d.lib
opencv_ml243d.lib
opencv_objdetect243d.lib
opencv_ts243d.lib
opencv_video243d.lib
这样，该设置对所有VC项目都有效；
这种方法修改的结果会保存到%USERPROFILE%\appdata\local\microsoft\msbuild\v4.0下面的文件：
Microsoft.Cpp.Win32.user.props。如果是64平台则是反应到Microsoft.Cpp.X64.user.props文件中。这两个文件都是在安装VS2010时产生的。
1、定位到%USERPROFILE%\appdata\local\microsoft\msbuild\v4.0（可以通过运行，或直接在windows资源管理器的地址栏中输入）。

MySQL BLOB: how to optimize BLOBs requestsMay 13, 2025 am 12:03 AMOptimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.
Adding Users to MySQL: The Complete TutorialMay 12, 2025 am 12:14 AMMastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

MySQL: String Data Types and Indexing: Best PracticesMay 12, 2025 am 12:11 AMBest practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database 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),
