Visual Studio 2015 for Visual Studio 6 Code Compatibility

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
我在 VC++6 的配置管理器中没有看到任何选项。
我认为可能还有其他一些配置选项，但对此知之甚少。让我知道是否有人可以提供帮助。
此外，我必须重用代码并使用适用于Android和IOS手机的VS Studio 2015跨平台IDE构建应用程序
。那么如何升级应该与最新版本的VC++兼容的VC++6代码。同时，这表明：
Visual Studio2012 和 Visual Studio 2013 不支持调试 使用 Visual C++ 6 构建的应用程序;若要调试这些应用程序，请使用 早期版本的 Visual Studio。
我应该先从 VC++6 -> VC++2010 升级项目，然后再使用更高版本构建项目，还是有直接的方法？

_CRT_SECURE_NO_WARNINGS就是 - 警告 - 您的代码仍然可以编译（并且不亚于在VC++6中编译时的安全性）。您遇到的唯一错误（来自您的输出）是以下形式：
Pewrap.cpp(551): error C2065: 'i': undeclared identifier
我将假设"i"是一个 for 循环索引变量，并且您的 VC++6 项目使用Microsoft语言扩展，以便循环变量声明在循环后持久化。我还猜测在您的VS2015项目中，禁用语言扩展/Za（属性页->C/C++->语言）处于打开状态，因此，使用"i"的第一个循环有效，其余循环给出错误。要么不要禁用语言扩展，要么在你使用它的每个循环中（或在更高的范围内）声明"i"。
正确声明"i"是最便携的方法，因为它不依赖于任何语言扩展。例如。你有这个：
for(int i=0;i<NO_OF_FUNCTIONS;i++)
...
for(i=0;i<pImage->FileHeader.NumberOfSections;i++)
...
将"i"的第一个用法更改为：
int i;
for(i=0;i<NO_OF_FUNCTIONS;i++)
在"解决方案资源管理器"中选择项目，右键单击"属性"。C/C++> 预处理器。
对所有配置/所有平台重复此步骤，方法是从顶部保管箱更改配置（调试/发布）/平台（x86/x64），并保存每个配置/平台的配置。
编辑预处理器定义。添加以下定义"_CRT_SECURE_NO_WARNINGS" - 它将禁用函数兼容性警告。
您显示的唯一消息是无害警告。与您的评论相反，当您定义_CRT_SECURE_NO_WARNINGS时，它们确实会消失。如果没有，则说明您没有正确定义符号或为正确的文件定义符号。
我在另一篇文章中看到提到了'i': undeclared identifier错误，但在您的摘要中没有。如果出现后者，这确实是循环内变量声明的范围规则的变化，该声明使用/Zc 选项（C++/语言/For 循环范围内的强制一致性）进行管理。
