This month's community call features presentations - Dialog API security updates (recent changes to dialog API that address a security vulnerability requires action from you IF your add-in uses cross-domain communication between the dialog and taskpane. Requirements and timeline with grace period), PowerPoint API update: Shape object (preview the new Shape APIs – insertion APIs along with ability to manipulate basic, line & fill, text frame & range properties of these objects.), and PnP: Open in Teams (access data hosted on a website inside a Microsoft Teams channel for purposes of collaborating on the data). This month’s Community spotlight recognizes MVP Maarten van Stam for his continued contributions. Thank you! Q&A in chat throughout call. The call was hosted by David Chesnut (Microsoft) | @davidchesnut. Microsoft Presenters: Lillian Liu - Senior Program Manager and Onur Onder, Senior Software Engineer. Recorded August 11, 2021.
- Dialog API security updates - Lillian Liu, Senior Program Manager (Microsoft) – 01:00
- PowerPoint API update: Shape object - Onur Onder, Senior Software Engineer (Microsoft) – 05:02
- PnP: Open in Teams - David Chesnut, Senior Dev Writer (Microsoft) | @davidchesnut – 13:08
- Q&A – 28:15
- PowerPoint API update: Shape object – overview and live demo of the new Shape APIs – insertion APIs (Geometric Shapes, Lines, Text Boxes) along with ability to manipulate properties of these objects. Some of these API’s are available now on PowerPoint Online. APIs to be released in Windows Desktop and MAC builds in September - October. User customized shapes may be saved, applied to master slide view.
- PnP: Open in Teams – access data hosted on a website inside a Microsoft Teams channel for purposes of collaborating on the data. Teams detects the web-based data set on site, prompts viewer to open. If opened, then data (in memory using OOXML) is written to a spreadsheet and saved in OneDrive via Graph. Code sample available. Script Lab add-in uses Graph APIs and ASP.NET.
Q&A (Question & Answers)
In response to your post about runtimes and XML errors - I am also having the same issue. It appears to be a bug in Visual Studio 2019 (https://github.com/OfficeDev/office-js/issues/1756). I've not worked out how to get around it just yet. Any advice would be welcome please.
We recently added some guidance about how to update the XSD files in Visual Studio to solve this problem. For full details, see Troubleshoot development errors with Office Add-ins - Manifest schema validation errors in Visual Studio projects.
When is the GA for custom contextual tab on Mac?
We don't have an ETA on this yet but hope to provide an update soon.
When can we expect addSvg method to be officially released and can you please provide us with a working example of this method? My attempts keep erroring with "this picture can't be displayed"!
There are some issues holding us back from releasing the addSvg API to general availability. We’ll update you as soon as we have a definitive timeline for when it will go to GA.
Here is a sample that you can paste into Script Lab. It will insert a yellow circle into the spreadsheet.
Note that in Script Lab you need to go to the libraries tab and use https://appsforoffice.microsoft.com/lib/beta/hosted/office.js since this is a preview API.
When will it be possible to change text on slides and slide masters?
As Onur showed in his demo on the community call, these features will be coming out sometime in the next few months.
When is the Word API going to be updated?
We are looking to share some more information on the Word APIs around the September timeframe.
Is there a known bug or lack of support for insertFileFromBase64() with Word 97-2003 documents?
The insertFileFromBase64 API does not support Word 97-2003 document formats. This is primarily a design artifact of supporting Word on the web, which only supports .docx and .dotx formats.
Will you support manipulating the Tags property of Shape objects (as well as Slide and Presentation objects)? Developers REALLY like to store information in Tags objects.
Yes, tag support is currently in preview - https://docs.microsoft.com/office/dev/add-ins/reference/requirement-sets/powerpoint-preview-apis
How do I add an officeGroup to my CustomTab for my Word add-in? I can't seem to find much info on this.
officeGroup is currently only supported for PowerPoint. We plan to support Word and Excel in the future but we don't have an ETA just yet.
Could we manage the shape object in a different slide?
Yes. context.presentation.slides has a collection of slides. Use the slide.shapes collection to access a shape on another slide.
Do the shape APIs work with placeholder shapes, both in Normal and Slide Master view?
Yes. Shape APIs work with placeholder shapes, both in Normal and Slide Master view.
Can we change a shape's alt text?
Unfortunately alt text editing is not supported at this time with this set of APIs.
When will the shape APIs be available in Excel?
Will the shapes API also include things like pictures and tables?
The Shapes collection will have information about the shape type. This means you can differentiate between pictures and other shapes. Some of the fill and line properties also applies to pictures, so those can be updated too. But there won't be more picture specific APIs in this update.
Can the shapes API be used to copy existing shapes between slides?
Not yet. We are looking to provide this capability in a future update.
We're trying out the beta of shared/delegated mailbox support and finding that in OWA, we still can't open a shared mailbox. We get the error: "The operation on mailbox failed because it's out of the current user's write scope." There are more details here(https://docs.microsoft.com/en-us/answers/questions/506662/outlook-owa-addin-installation-permission-issue-de.html). Is this something we can expect to work in the release?
This is a known outcome and you can find more information, including how to set up the mailboxes to work, in this GitHub issue: https://github.com/OfficeDev/office-js/issues/1877#issuecomment-897097347
Does SSO (getAccessToken) work for an add-in online inside of Word inside of Teams?
Using SSO from Word inside of Microsoft Teams is not supported today. But we are working on enabling this in the near future and hope to share some more information soon.
Say a user has an Office 365 license, but has only ever used Excel for Windows. They also have access to Teams. If we open an Excel workbook in Teams, will they always be able to see and work with it? Are there any Office licensing issues?
There shouldn't be any licensing issues, as long as they are licensed for Microsoft 365 (the new name for Office 365).
Last month I asked about the ability to change the width of a task pane in Outlook. Can someone update me or share a link to the response from last month?
Thanks for asking about this again. We unfortunately lost some of the Q&A from the last chat.
Currently the user can change the task pane width in Word, Excel, and PowerPoint. However you can't set the task pane width programmatically. That is on our backlog but we don't have an ETA for when we'll implement this feature.
Outlook on the web does not support task pane resizing, and setting task pane width is not on the backlog for Outlook. Outlook scenarios can be slightly different, so if you want to create a feature request with more details, that would be helpful. You can create a feature request at Microsoft 365 Developer Platform - Microsoft Tech Community.
In the Word API, is there a way to restrict the document editing with Office.JS? I’m looking at document level editing control, not content controls.
Right now, restricting document editing is not part of the Word APIs. However this sounds like a great feature request to make at Microsoft 365 Developer Platform - Microsoft Tech Community.
Can you recommend any books, training or certification courses for development in Office.JS?
For books you might take a look at Building Office Add-ins Using Office.js. There isn't a specific certification for Office Add-in development, but there is a Microsoft 365 Certified: Developer Associate certification. There is an Office Add-in specific learning at Extend Office clients with Office add-ins – Associate - Learn | Microsoft Docs.
Does anyone know when VSTO will reach official end of life?
We continue to support the VSTO and VBA technologies and keep them healthy and secure.
Is there way to retrieve the previous value of a cell from inside of a custom function?
We don't have official support for custom functions to share previous values. But there are mechanisms available that let you enable this. You need to configure your add-in to use the shared runtime. Cache the results back from your custom function, and use the caller.address parameter so you know where the custom function was being called from (where you can get the old value from your cache).
Is supporting encrypted S/MIME messages and compose mode on Outlook for mobile on the road map?
This is on our backlog but we don't yet have an ETA for when this could be available.
