在visual studio 6.0中使用winhttp [英] Use winhttp in visual studio 6.0
问题描述
我正在维护一个用Visual Studio C ++ 6.0编写的遗留应用程序。
我需要通过调用WinHTTP API替换部分代码。
我在Visual Studio 6.0测试项目中创建了一个小型演示，所以我可以看看情况如何。
当我构建代码我得到以下错误（相同的代码在Visual Studio 2013中完美运行）：
致命错误C1083：无法打开包含文件：'winhttp.h'：没有这样的文件或目录
我添加了包含路径，就像在这个 [ ^ ]图片。
我添加了库的路径，例如这个 [ ^ ]图片。
尝试编译后我明白了：
I am maintaining a legacy app written in Visual Studio C++ 6.0.
I need to replace portion of the code with calls to WinHTTP API.
I have created small demo in Visual Studio 6.0 test project so I can see how would things go.
When I build the code I get the following error ( the same code works flawlessly in Visual Studio 2013 ) :
fatal error C1083: Cannot open include file: 'winhttp.h': No such file or directory
I have added the Include path, like in this[^] image.
I have added the path to library, like in this[^] image.
After trying to compile I get this:

fatal error C1004: unexpected end of file found
将新添加的路径移到顶部后，我只有一个错误：
c：\ program files（ x86）\ microsoft sdks\windows\v7.1a\include\specstrings.h（11）：致命错误C1083：无法打开包含文件：'sal.h'：没有这样的文件或目录
我有复制/粘贴 sal.h 和 ConcurrencySal.h 进入VC98 / Include，并有复制/粘贴目录 CodeAnalysis 。
现在我收到以下错误：
After moving the newly added paths to the top, I have got only one error:
c:\program files (x86)\microsoft sdks\windows\v7.1a\include\specstrings.h(11) : fatal error C1083: Cannot open include file: 'sal.h': No such file or directory
I have copy/pasted sal.h and ConcurrencySal.h into VC98/Include, and have copy/pasted directory CodeAnalysis as well.
Now I get following errors:

问题：
你能解释一下如何设置一个Visual C ++ 6中的项目，所以它可以使用WinHTTP API（当然，如果可能的话）？
我尝试过：
在我正在谷歌搜索解决这个问题...

推荐答案
您正在尝试使用Windows SDK版本7.1A与Visual Studio 6.这不会工作。
支持Visual Studio 6的最后一个SDK是Microsoft Platform SDK 2003年2月（版本5.2.3790.0）（来源： Microsoft Windows SDK - Wikipedia [ ^ ]）。请注意，您必须安装完整的SDK才能包含WinHttp标头和库文件。
所以你有三个选择：
You are trying to use the Windows SDK version 7.1A with Visual Studio 6. This won't work.
The last SDK that supports Visual Studio 6 is the Microsoft Platform SDK February 2003 (version 5.2.3790.0) (source: Microsoft Windows SDK - Wikipedia[^]). Note that you have to install the full SDK to have the WinHttp header and library file included.
So you have three options:
- 使用较新的Visual Studio版本构建应用程序的端口
- 使用WinINet API而不是WinHTTP API
- 安装用于Visual Studio 6的完整PSDK 2003年2月以上
因为winhttp是一个高级API，所以必须包括首先是标准的Windows标题 。这将解决代码中的大多数问题。
正确的方法是使用大括号：
Because winhttp is a high level API you MUST include the standard windows header at first . That will solve the most problems in your code.
the correct way is with braces:
#include <windows.h>
#include <winhttp.h>
在最后一个位置设置sdk搜索路径以避免冲突。并且您必须在链接器选项卡上包含winhttp.lib文件。
另请参阅winhttp示例。
你最好使用一些永不版本在Visual Studio中，我更喜欢VS 2005或VS 2010。
Set the sdk search path at the last position to avoid collisions. And you must include the winhttp.lib file on the linker tabs.
Take also a look at the winhttp examples from Microsoft.
You better use some never version of Visual Studio, I prefer the VS 2005 or VS 2010.
