Άρθρο
08/27/2024

In this article, you'll walk through the process of building a PowerPoint task pane add-in.

Prerequisites

Visual Studio 2019 or later with the Office/SharePoint development workload installed.

Note

If you've previously installed Visual Studio, use the Visual Studio Installer to ensure that the Office/SharePoint development workload is installed.
Office connected to a Microsoft 365 subscription (including Office on the web).

Create the add-in project

In Visual Studio, choose Create a new project.
Using the search box, enter add-in. Choose PowerPoint Web Add-in, then select Next.
Name your project and select Create.
In the Create Office Add-in dialog window, choose Add new functionalities to PowerPoint, and then choose Finish to create the project.
Visual Studio creates a solution and its two projects appear in Solution Explorer. The Home.html file opens in Visual Studio.

Explore the Visual Studio solution

When you've completed the wizard, Visual Studio creates a solution that contains two projects.

Project	Description
Add-in project	Contains only an XML-formatted add-in only manifest file, which contains all the settings that describe your add-in. These settings help the Office application determine when your add-in should be activated and where the add-in should appear. Visual Studio generates the contents of this file for you so that you can run the project and use your add-in immediately. Change these settings any time by modifying the XML file.
Web application project	Contains the content pages of your add-in, including all the files and file references that you need to develop Office-aware HTML and JavaScript pages. While you develop your add-in, Visual Studio hosts the web application on your local IIS server. When you're ready to publish the add-in, you'll need to deploy this web application project to a web server.

Description

Add-in project

Contains only an XML-formatted add-in only manifest file, which contains all the settings that describe your add-in. These settings help the Office application determine when your add-in should be activated and where the add-in should appear. Visual Studio generates the contents of this file for you so that you can run the project and use your add-in immediately. Change these settings any time by modifying the XML file.

Web application project

Contains the content pages of your add-in, including all the files and file references that you need to develop Office-aware HTML and JavaScript pages. While you develop your add-in, Visual Studio hosts the web application on your local IIS server. When you're ready to publish the add-in, you'll need to deploy this web application project to a web server.

Update the code

Home.html specifies the HTML that will be rendered in the add-in's task pane. In Home.html, replace the <body> element with the following markup and save the file.

<body class="ms-font-m ms-welcome">
    <div id="content-header">
        <div class="padding">
            <h1>Welcome</h1>
        </div>
    </div>
    <div id="content-main">
        <div class="padding">
            <p>Select a slide and then choose the buttons to below to add content to it.</p>
            <br />
            <h3>Try it out</h3>
            <button class="ms-Button" id="insert-image">Insert Image</button>
            <br/><br/>
            <button class="ms-Button" id="insert-text">Insert Text</button>
        </div>
    </div>
</body>

Open the file Home.js in the root of the web application project. This file specifies the script for the add-in. Replace the entire contents with the following code and save the file.

'use strict';

    Office.onReady(function() {
        // Office is ready
        $(document).ready(function () {
            // The document is ready

            $('#insert-text').on("click", insertText);
        });
    });

    }  

    function insertText() {

Try it out

Using Visual Studio, test the newly created PowerPoint add-in by pressing F5 or choosing the Start button to launch PowerPoint with the Show Taskpane add-in button displayed on the ribbon. The add-in will be hosted locally on IIS.
In PowerPoint, insert a new blank slide, choose the Home tab, and then choose the Show Taskpane button on the ribbon to open the add-in task pane.
In the task pane, choose the Insert Image button to add an image to the selected slide.
In the task pane, choose the Insert Text button to add text to the selected slide.

Note

To see the console.log output, you'll need a separate set of developer tools for a JavaScript console.

Congratulations, you've successfully created a PowerPoint task pane add-in! Next, learn more about developing Office Add-ins with Visual Studio.

Troubleshooting

Ensure your environment is ready for Office development by following the instructions in Set up your development environment.
Some of the sample code uses ES6 JavaScript. This isn't compatible with older versions of Office that use the Trident (Internet Explorer 11) browser engine. For information on how to support those platforms in your add-in, see Support older Microsoft webviews and Office versions. If you don't already have a Microsoft 365 subscription to use for development, you might qualify for a Microsoft 365 E5 developer subscription through the Microsoft 365 Developer Program; for details, see the FAQ. Alternatively, you can sign up for a 1-month free trial or purchase a Microsoft 365 plan.

If your add-in shows an error (for example, "This add-in could not be started. Close this dialog to ignore the problem or click "Restart" to try again.") when you press F5 or choose Debug > Start Debugging in Visual Studio, see Debug Office Add-ins in Visual Studio for other debugging options.
