HarmonyOS NEXT Practical: Save Network Images

Objective: Display network images, download them by clicking the save button, and save them locally.

Prerequisite: ohos.permission.INTERNET Permission application required

Implementation idea:

Display images through Image.

Obtain operational permissions through SaveButton.

Download images through request.downloadFile.

Copy images locally through fileIo.

Specific implementation [code] import { http } from '@kit.NetworkKit'; import { image } from '@kit.ImageKit'; import { BusinessError, request } from '@kit.BasicServicesKit'; import { photoAccessHelper } from '@kit.MediaLibraryKit'; import { promptAction } from '@kit.ArkUI'; import { fileIo, fileIo as fs, fileUri } from '@kit.CoreFileKit'; import { common } from '@kit.AbilityKit';

[[Power Automate for desktop]名前を付けて保存ダイアログを操作するフロー]

前回の記事でUI要素のセレクターで変数が使用できることを説明しましたが、今回はその応用で、様々なアプリケーションで使える「名前を付けて保存ダイアログを操作するフロー」を作成してみようと思います。 入力変数の作成 「Desktop フローを実行」アクションで呼び出すことを前提とするため、まずは名前を付けて保存ダイアログの親となるウィンドウのセレクターを指定する「ParentWindowSelector」と、ファイルの保存先パスを指定する「SaveFilePath」を作成します。 「名前を付けて保存ダイアログ操作」フロー 下記コードをデザイナーに貼り付けます。 3つのUI要素(親ウィンドウを示す「ParentWindow」、ファイルパスの入力欄を示す「FileName」、保存ボタンを示す「SaveButton」)とダイアログを操作する2つのアクション(ウィンドウ内のテキスト…

The save button is not the flag for inappropriate content here on Instagram (or IG). This icon is used to save articles, posts, and publishings that may interest you for later use. ⛅ I also know that you are willing to help yourself by helping others as I do right now because of a mistake.
