强大的数据库查询工具Database.NET 9.4.5018.42
两个工具的下载地址，两个软件都是绿色免安装的，直接双击运行：
Database.Net
SQLite Database Browser
这几天在写一个程序，需要用到SQLITE，但是对于SQLITE不熟悉，在网上找了一个SQLITE查看器
这个查看器叫做：SQLite Database Browser 2.0
这个查看器可以新建SQLITE文件数据库，可以建立表索引，写SQL语句，编辑表数据
不过这个查看器支持的SQLITE数据库引擎版本低了一点
在介绍Database.Net之前，先介绍一下SQLite Database Browser 2.0
主界面
将SQLITE的db文件拖进去软件就可以了，不用点击“打开”按钮
新建数据库
由于新建数据库的时候，软件的保存类型为ALL Files，新建完毕之后会发现文件没有后缀名，这个时候你可以先close database
重命名一下数据库文件，比如新建数据库的时候，文件名为123，那么可以重命名为123.db
如果用editplus来打开，会看到文件头有SQLite format 3的字样
在软件的标题栏可以看到数据库文件的路径
编写并执行SQL语句
浏览数据并且编辑表数据
修改表数据完毕后，记得点击“Apply Changes”按钮
修改表结构
重命名表名，添加字段，修改字段，删除字段
修改表结构，建立索引，建立新表之后都要点击一下保存按钮，不然的话所做的修改无效
似乎介绍SQLite Database Browser 2.0这个工具的篇幅多了一点
现在介绍Database.Net
先说一下我用的版本，我用的是9.4.5018.42
台湾人写的，这个作者做软件非常专业，至于有多专业，大家用一下就知道了
官方网站：
从上图看出这个作者做了很多软件，应该挺有名的
不说了，继续o(∩_∩)o
在关于窗体里，列出了这个工具用到的各个数据库的类库和类库的版本，其他数据库类库版本我就不说了，因为不是很熟悉
这个软件应该是用.NET写的，.NET人熟悉的SqlClient类，版本是4.0.0.0，比较新
这个工具的目的：尽量代替各种数据库管理软件，用一个DATABASE.NET来管理各种数据库，如果有多种数据库要管理就不用
安装各种数据库的管理软件了，例如ORACLE的客户端软件，SQLSERVER的SSMS，，MYSQL的Navicat，office等等
打开软件之后，选择连接的数据库
比如连接ACCESS数据库
打开ACCESS数据库，打开之后，会看到多了一个ldb文件
无论你用office的ACCESS打开还是用DATABASE.NET打开都会产生ldb文件的
打开表数据
编辑表数据是收费功能，目前在网上找不到DATABASE.NET的注册码，不过就算不用收费功能，也足够用了
任务栏上的图标非常传神，当前打开的数据库类型一看就知道了
ACCESS的一些高级功能也可以在DATABASE.NET里面使用，不过SQL探查器是付费功能
你当前连接的数据库文件的版本，连接的是ACCESS2003文件
如果是SQLITE，SQLSERVER，ORACLE都会在右面显示当前连接的数据库引擎的版本
创建ACCESS数据库的步骤就不说了，大部分文件数据库，例如：ACCESS，SQLITE，SQLCE都可以在DATABASE.NET里创建
这个软件还支持多国语言，都是调用相应国家的xml语言文件
我们公司系统的多国语言功能也是这样做的
可以查看Windows服务管理器里，有什么数据库服务正在运行
查询窗口选项
执行SQL语句
快捷键是F5，跟SQLSERVER的SSMS是一样的
你要断开连接才能连接其他的数据库，一次只能连接一个数据库
比如，我连接到SQLSERVER，他支持连接到LocalDB，LocalDB是SQLSERVER2012才出来的，说明这个软件还是在不断更新的
在空白的地方，点击属性可以看到当前连接的SQLSERVER数据库引擎的版本情况
SQLITE
这个软件好在有简单的SQL语句语法提示，例如SQLSERVER里使用top关键字，而SQLITE里使用limit关键字来查询一定行数的表数据
修改表结构
创建表索引
创建表触发器
在空白的地方点击属性就可以看到当前这个SQLITE文件的版本
版本号：3.7.17
比SQLite Database Browser所支持的版本还要高
如有不对的地方，欢迎大家拍砖o(∩_∩)o

How to use the chrono library in C?
Apr 28, 2025 pm 10:18 PM
Using the chrono library in C can allow you to control time and time intervals more accurately. Let's explore the charm of this library. C's chrono library is part of the standard library, which provides a modern way to deal with time and time intervals. For programmers who have suffered from time.h and ctime, chrono is undoubtedly a boon. It not only improves the readability and maintainability of the code, but also provides higher accuracy and flexibility. Let's start with the basics. The chrono library mainly includes the following key components: std::chrono::system_clock: represents the system clock, used to obtain the current time. std::chron
How to measure thread performance in C?
Apr 28, 2025 pm 10:21 PM
Measuring thread performance in C can use the timing tools, performance analysis tools, and custom timers in the standard library. 1. Use the library to measure execution time. 2. Use gprof for performance analysis. The steps include adding the -pg option during compilation, running the program to generate a gmon.out file, and generating a performance report. 3. Use Valgrind's Callgrind module to perform more detailed analysis. The steps include running the program to generate the callgrind.out file and viewing the results using kcachegrind. 4. Custom timers can flexibly measure the execution time of a specific code segment. These methods help to fully understand thread performance and optimize code.
How to use string streams in C?
Apr 28, 2025 pm 09:12 PM
The main steps and precautions for using string streams in C are as follows: 1. Create an output string stream and convert data, such as converting integers into strings. 2. Apply to serialization of complex data structures, such as converting vector into strings. 3. Pay attention to performance issues and avoid frequent use of string streams when processing large amounts of data. You can consider using the append method of std::string. 4. Pay attention to memory management and avoid frequent creation and destruction of string stream objects. You can reuse or use std::stringstream.
How to optimize code
Apr 28, 2025 pm 10:27 PM
C code optimization can be achieved through the following strategies: 1. Manually manage memory for optimization use; 2. Write code that complies with compiler optimization rules; 3. Select appropriate algorithms and data structures; 4. Use inline functions to reduce call overhead; 5. Apply template metaprogramming to optimize at compile time; 6. Avoid unnecessary copying, use moving semantics and reference parameters; 7. Use const correctly to help compiler optimization; 8. Select appropriate data structures, such as std::vector.
How to understand DMA operations in C?
Apr 28, 2025 pm 10:09 PM
DMA in C refers to DirectMemoryAccess, a direct memory access technology, allowing hardware devices to directly transmit data to memory without CPU intervention. 1) DMA operation is highly dependent on hardware devices and drivers, and the implementation method varies from system to system. 2) Direct access to memory may bring security risks, and the correctness and security of the code must be ensured. 3) DMA can improve performance, but improper use may lead to degradation of system performance. Through practice and learning, we can master the skills of using DMA and maximize its effectiveness in scenarios such as high-speed data transmission and real-time signal processing.
What is static analysis in C?
Apr 28, 2025 pm 09:09 PM
The application of static analysis in C mainly includes discovering memory management problems, checking code logic errors, and improving code security. 1) Static analysis can identify problems such as memory leaks, double releases, and uninitialized pointers. 2) It can detect unused variables, dead code and logical contradictions. 3) Static analysis tools such as Coverity can detect buffer overflow, integer overflow and unsafe API calls to improve code security.
What is real-time operating system programming in C?
Apr 28, 2025 pm 10:15 PM
C performs well in real-time operating system (RTOS) programming, providing efficient execution efficiency and precise time management. 1) C Meet the needs of RTOS through direct operation of hardware resources and efficient memory management. 2) Using object-oriented features, C can design a flexible task scheduling system. 3) C supports efficient interrupt processing, but dynamic memory allocation and exception processing must be avoided to ensure real-time. 4) Template programming and inline functions help in performance optimization. 5) In practical applications, C can be used to implement an efficient logging system.
How to implement loosely coupled design in C?
Apr 28, 2025 pm 09:42 PM
To implement loose coupling design in C, you can use the following methods: 1. Use interfaces, such as defining the Logger interface and implementing FileLogger and ConsoleLogger; 2. Dependency injection, such as the DataAccess class receives Database pointers through the constructor; 3. Observer mode, such as the Subject class notifies ConcreteObserver and AnotherObserver. Through these technologies, dependencies between modules can be reduced and code maintainability and flexibility can be improved.
