在 aliases.js 中，我试图从导入的 actionTypes 对象访问“SELECT_HOST”属性值。但是，根据 Webpack，这会导致“SyntaxError: Unexpected token, expected ,”错误。我无法确定actionTypes.SELECT_HOST访问对象属性值的标准点符号方式是什么语法错误。

actionTypes.js：

const actionTypes = {
    SELECT_HOST : 'SELECT_HOST',
    INVOKE_ASSESSMENT : 'INVOKE_ASSESSMENT',
    RETRIEVE_ASSESSMENT : 'RETRIEVE_ASSESSMENT',
    RETRIEVE_OPTIONS : 'RETRIEVE_OPTIONS',
    RETRIEVE_RESULTS : 'RETRIEVE_RESULTS',
    UPDATE_OPTIONS : 'UPDATE_OPTIONS'
};

export default actionTypes;

别名.js：

import actionTypes from '../actions/actionTypes';

const selectHost = (host) => {
    chrome.tabs.query({currentWindow: true, active: true}, (tabs) => {
        host = new URL(tabs[0].url).hostname;
    });
    const action = {
        type: actionTypes.SELECT_HOST,
        host
    };
    return action;
};

export default {
    actionTypes.SELECT_HOST: selectHost
};

我正在尝试使用 terraform 来设置 S3 + Cloudfront 静态站点。最初，我按照https://alimac.io/static-websites-with-s3-and-hugo-part-1/中的步骤成功设置了该网站

但是，后来我将 terraform 状态后端从 更改为localNow s3，当我执行时，terraform apply出现以下错误：

Error: Error applying plan:

2 error(s) occurred:

我试图根据基于任务的异步模式报告异步函数的进度.

using System;
using System.Threading.Tasks;

namespace TestConsoleApplication1
{
    class Program
    {
        static void Main()
        {
            Blah();
            Console.ReadLine();
        }

        static async void Blah()
        {
            var ProgressReporter = new Progress<int>(i => Console.WriteLine(i + "%"));
            await Foo(ProgressReporter);
        }

        static Task Foo(IProgress<int> onProgressPercentChanged)
        {
            return Task.Run(() =>
            {
                for (int i = 0; i < 1000; i++)
                {
                    if (i % 100 == 0)
                    {
                        onProgressPercentChanged.Report(i / 100);
                    }
                }
            });
        }
    }
}

但是,随着i不断更新,在打印之前,输出会混乱.示例输出:

1%
3%
0%

我正在开发一个SDI MFC应用程序,其中有一些自定义按钮以自定义方式绘制或者图像加载在它们之上.当正在运行的应用程序连续重新调整大小约5到10分钟时,它会因错误"未找到所需资源"而崩溃.

我已经彻底检查了代码,所有的GetDC()呼叫都跟着ReleaseDC()电话.此外,每当我DC.SelectObject(&newBrush)打电话然后恢复旧笔时,我总是保存旧的GDI对象(例如,oldBrush)DC.SelectObject(&oldBrush).

什么其他可能导致此错误的任何提示？

编辑:我使用程序Deleaker来查找程序中的GDI泄漏并删除导致泄漏的那些GDI对象.
