代码说明:

RS-485标准定义了一个极为坚固和可靠的通信链路,具有高噪声抑制、宽共模范围、长传输距离、冲突保护等特性。 但一个真正牢靠的RS-485网络还有赖于合理的应用。合理的网络布局、信号通道的连续性、周全的保护措施等,在设计之初就应该有一个总体规划-RS-485 standard definition of a very robust and reliable communication links with high noise suppression, and wide common-mode range, long-distance transmission, the conflict protection features. But a real solid RS-485 network also depends on the reasonable application. Logical network layout, channel signal of continuity, comprehensive protection measures, designed from the outset there should be an overall plan

  • QT下的字典
    在windows平台上运行的窗体程序,可以实现: 1、查询单词(查词典中的单词解释); 2、录入生词本(手动加入生词或者加入已有的词库单词); 3、生词本的删除、保存和读取操作; 4、数据保存到数据库中。     单词库和生词库都存放在数据库中,因此可以方便的对他们进行增、删、改、查,把每个窗口定义为一个类,实现一个模块功能,通过c++编写菜单来调用各个窗口,实现相应功能。

    Display a Web Page in a Plain C Win32 Application: There are numerous examples that demonstrate how to embed Internet Explorer in your own window. But these examples typically use Microsoft Foundation Classes (MFC), .NET, C#, or at least the Windows Template Library (WTL) because those frameworks have pre-fabricated "wrappers" to easily give you an "HTML control" to embed in your window. If you re trying to use plain C, without MFC, WTL, .NET, C#, or even any C++ code at all, then there is a dirth of examples and information how to deal with OLE/COM objects such as IE s IWebBrowser2. Here is an article and working example in C to specifically show you what you need to do in order to embed IE in your own window, and more generally, show you how to interact with OLE/COM objects and create your own objects in plain C.
