这是自己的一个小想法，但是最后还是经过2天的瞎鼓捣实验成果了。虽然界面很丑，但是我很喜欢它，因为有Dos黑窗口，少去了安装步骤，更多的是少去了广告，基于有道翻译里面的api接口，所以我不怕翻译的不准确啦 首先这里分三大步进行肢解： 一： 有道词典的API接口爬取： 二：tkinter 各种控件的使用: 三：PyInstaller 打包成exe文件，直接在桌面上进行应用： 首先：我们来获取有道词典的API接口； 打开网址： 网址 http://fanyi.youdao.com/ 这里通过HttpFox 拦截请求中我们可以看到，我们在网址： http://fanyi.youdao.com/ 中输入中国的时候，调用了post接口，这里的post 参数我把它特别的截出来了，其中key 为i 的value值 是一个乱码的，这里后面会一会就有讲到，里面post参数都有罗列。 相对于中文的翻译，英文的就很好的看到了， 我们可以直接看到对于i的value值为china 通过查看网页源代码的方式查看有道翻译的js文件，来查看salt和sign是怎么生成的 这里的sign值是进行了md5加密来着 贴上有道API代码的获取： # -*- coding: utf-8 -*- # @Time : 2017/8/28 0:42 # @Author : 蛇崽 # @Email : 17193337679@163

In windows; there are 2 options to link to a CRT: Multithreaded, static link Multithreaded, dynamic link Can someone shed some light on what is the best practice here? Should I link 'statically' to the CRT or do a dynamic link? If i do a dynamic link, and I write a program that uses my DLL + another 3rd party DLL (which is doing a static link to CRT), is that an issue? This is a Big Deal when you use DLLs in your application. It is very important that the EXE and the DLLs use the same memory allocator. In case you return pointers or C++ objects (like std::string) from a DLL function that needs

I have a C++ code base that has been working for a long time. The code base was a legacy VS 2003 set of projects that I recently migrated to VS 2008. The migration seemed to be successful in that the resulting program built, and run. I reinstalled my OS and all applications on a fresh drive, and now when I attempt to debug the program within the debugger, I receive an assertion error inside the CRT's chsize (really, _chsize_s ). Specifically (cropped to essentials, ignoring safety checks): FILE * testfile = fopen("P:\\_Dan\\local\\foogoo.txt", "w"); int filehandle = fileno(testfile); chsize

I was asked to help converting a certificate for a renewal. I was given the domainname.crt file along with some intermediate .crt files, but no .key file. They want me to convert the CRT to both a .CER and a .KEY file. I have looked at the following (among many other sites) but they either say I need the .key file, which I don't have, or that I have to install it locally and then export it, but when using MMC and trying to export it the .PFX option is grayed out. http://community.spiceworks.com/topic/367133-i-cant-convert-a-ssl-crt-to-pfx-i-need-help-with-this I also tried the OpenSSL command

本文简要整理了 MSDN 上关于 “ Security Features in the CRT ” 方面的内容。详细参考 官网 。 许多老旧的 CRT 函数都有更新且更加安全的后续版本。在安全版本存在的情况下，老旧版本都会被标识为废弃（deprecated）的状态，而安全版本都会以 "_s" 作为后缀。 注意 ：上面提到的废弃的状态 不代表 函数已经从 CRT 中被移除，而是 表示 不推荐使用。而安全版本同样不能阻止或者自行修正安全错误，而是其能够在这类错误发生时将错误进行捕获，因为这类函数会对发生的错误条件进行额外的检查。 【消除废弃警告】 方法一：定义 _CRT_SECURE_NO_WARNINGS 宏，或者直接使用 #pragma warning( disable : xxxx ) 。这种方法只能起到眼不见心不烦的效果。 方法二：使用 “ 安全模板重载（Secure Template Overloads,） ”的方法。这种方法是通过重载的方式将老旧版本替换为新的安全版本来真正做到安全增强的，与此同时，老旧版本函数的名字仍旧可以照常使用。使用该方式时，需要定义宏 _CRT_SECURE_CPP_OVERLOAD_STANDARD_NAMES 。对于默认不存在“安全模板重载”的那些函数，需要自行手动更新你的代码来达到使用安全版本的效果。 方法三

I'm working on legacy code for Windows platform. When I compile the code in VS2013 , it give following warning: error C4996: ' fopen ': This function or variable may be unsafe. Consider using fopen_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details." And it will also give samiliar warning for sprintf . I understand sprintf_s is more safe than sprintf because of buffer overflow. But how can be fopen_s be more safe than fopen , there is no chance of buffer overflow because fopen doesn't accept an buffer. Can anyone provide an case fopen is unsafe, and

The library loader efficiently analyzes these dependencies, calculates the correct load order, and loads the DLLs in that order." [1] "(within DLLMain) Use the memory management function from the dynamic C Run- Time (CRT). If the CRT DLL is not initialized, calls to these functions can cause the process to crash." [2]
