在Visual Studio 2019中编译ATL项目时在propidlbase.idl中重新定义错误

问题描述

我正在尝试将以前的旧项目从Visual Studio 2010迁移到Visual Studio的当前版本（2019）。我是Microsoft有关升级的变更说明，与以前的做法相比，VS 2019中使用ATL属性似乎有所变化。

我能够编译该项目，因为尝试在Visual Studio 2019中编译该项目时遇到了一堆重新定义错误。

这是我的stdafx.h文件中的内容：

#pragma once
#include <SDKDDKVer.h>
#include <atlbase.h>
#include <atlcom.h>
#include <atlwin.h>
#include <atltypes.h>
#include <atlctl.h>
#include <atlhost.h>
#include <comdef.h>

using namespace ATL;

深入研究代码，看起来像#if宏触发了包含第二个定义的内容。来自propidlbase.idl

cpp_quote("#if WINAPI_FAMILY_PARTITION(WINAPI_PARTITION_APP | WINAPI_PARTITION_SYstem)")

这与项目或编译器设置有关吗，或者我是否需要另一个#define？为了在应用程序项目中使用ATL属性，是否有特别需要设置的隐式解决方案设置（即2019年）？

编辑：根据Simon的评论，这是我尝试使用midl编译的生成的idl文件的导入：

解决方法

您应该以oa / oc / ole idls开始，并且不要使用直接的SDK路径，否则，midl编译器很可能会感到困惑。

只需确保midl.exe在路径中（例如使用Visual Studio 2019 developer command prompt时），并使用简化的.idl即可，如下所示：

import "ocidl.idl";
import "oleidl.idl";
import "oaidl.idl";

import "wincrypt.idl";
import "prsht.idl";
import "objidl.idl";
import "unknwn.idl";
import "propidlbase.idl";
import "urlmon.idl";
import "servprov.idl";
import "msxml.idl";
import "comcat.idl";
import "atliface.idl";
import "oleacc.idl";
import "shtypes.idl";
import "MsHTML.idl";
import "dimm.idl";
import "dispex.idl";
import "dxgitype.idl";
import "dxgicommon.idl";
import "dxgiformat.idl";
import "MsHtmHst.idl";
import "docobj.idl";
import "ExDisp.idl";
import "ObjSafe.idl";

根据Microsoft Documents，错误https://docs.microsoft.com/en-us/azure/databricks/administration-guide/access-control/workspace-acl为：您的工具链设置为自动引用系统名称空间中的任何类型。在您的IDL文件中，删除Windows名称空间的任何FileModel fileModel = DependencyService.Get<IImageFetcher>().ReadImagesAsync(); var items = new List<FileImageInfo>(); for (int i = 0; i < fileModel.Images.Count; i++) { var imageStream = ImageSource.FromStream(() => new MemoryStream(fileModel.Images[i])); items.Add(new FileImageInfo { FileType = "Jpeg",FileSize = fileModel.Sizes[i],DateCreated = fileModel.Dates[i],imageSource = imageStream }); } Items.ItemsSource = items;指令；您只需import就可以在项目中定义任何类型。

您可以编辑stdafx.h并参考此MIDL2003以获得更多信息。
