嗨!

我是wpf应用程序开发的新手.我只是创建一个演示应用程序,我看到黑色框出现在我的应用程序的顶部.任何人都可以告诉我如何删除它？

对不起,我甚至都不知道它的名字.

我一直在使用Ubuntu 16.04。最近我对 PHP 安装做了一些实验，恐怕我已经严重破坏了东西。我试过

sudo apt install php7.0

但它显示了依赖性和损坏的包错误

所以，这就是我正在尝试做的事情。我使用 docker 创建了一个 MongoDB 服务，并尝试使用 mongoose 将我的 NodeJs 项目连接到数据库服务。这是我的docker-compose.yaml

version: '3'

services:

  mongodb:
    container_name: mongo_database
    image: mongo
    environment:
      - MONGO_INITDB_ROOT_USERNAME=admin
      - MONGO_INITDB_ROOT_PASSWORD=password
    networks:
      - mongo-compose-network
    ports:
      - '27017:27017'

  mongo-express:
    container_name: mongo_express
    image: mongo-express
    restart: unless-stopped
    depends_on:
      mongodb:
        condition: service_started
    networks:
      - mongo-compose-network
    environment:
      - ME_CONFIG_MONGODB_ADMINUSERNAME=admin
      - ME_CONFIG_MONGODB_ADMINPASSWORD=password
      - ME_CONFIG_MONGODB_SERVER=mongodb
    ports:
      - '8081:8081'

networks:
  mongo-compose-network:
    driver: bridge

我已经打开 mongo-express 面板，一切正常。现在，这是我的 NodeJs 应用程序，用于MongoClient连接到数据库并插入虚拟记录。

require('dotenv').config();

// required modules
const mongoose          = require("mongoose")
const MongoClient       = require('mongodb').MongoClient;

// database config
const …
