![]() ![]() Which option to use depends on the chosen data structure within the data store. Example: SharePoint has the possibilities to add an image as a list item attachment or within a library. The possibility to add an image to an entity depends on the entity data store. PowerApps is very well suited for adding the image related value to an entity after scanning it or adding it manually. Software could also already have the option built-in to show an image based on another field. Often, an entity does not have to be enriched with an image. This should be stored in a separate field. The reason is not storing the related value. The main reasons to enrich an entity with an image are performance and to be independent of image generation services/software in the future, which could result in additional costs. The enrichment of an entity with a barcode/QR code image Generating unique values is usually left to the data store the entities are stored in, like SharePoint Online or the Common Data Service. Yes, a guid (or something similar) can be created and when you assume this will be unique, then it is ok. PowerApps is not really a tool for generating a unique number for an entity on its own. Creating images up-front could be useful for organizations which use free services. Which one is useful and/or possible depends on your situation and solution. Images can be created in real-time or up-front. For them, the second activity which is described in the next section is more important. This is often combined with printing them as well. Some companies already have devices or software which generates images. Free services are of course very useful for demo/testing purposes. There are some free services but I would never advice an organization to use a free service when there is no commitment and track record about continuation and without a good fallback plan. Often, more is needed.Ī better solution in my opinion is to use a paid service which creates image files. Depending on the solution you want to create, this could be enough. SharePoint has an option to show barcodes images. For very specific situations, PowerApps supports the second option too, but these situations are not very likely in my opinion.įrom now on, when talking about an image, a barcode/QR code image is meant. PowerApps supports the third and fourth option, but with the help of Microsoft Flow and other services/software, the other options are possible too. The enrichment of an entity with a barcode/QR code image.The creation of a barcode/QR code image.He following activities can happen when working with barcode/QR code images: The value often is a unique number representing an entity like a person, product or event registration, but in practice more representations are possible like a set of choices or an url. I also mention my personal experience with the new scanning functionality in section “Scanning a barcode/QR code image”.īarcodes/QR codes are often used for activities like: The rest of this blog post gives a more architectural and practical view on working with barcode/QR code images in relation to PowerApps. Using a button is at the moment already the way to go to get the value and navigate to a different screen. Pushing a button is a way to trigger this and it also means that subsequent actions can be set, like navigating to another screen. One of the changes is that a function is used to trigger the usage of the native API's: ScanBarcode(). On the iPhone 4s I used for testing, I could not use this though. For instance, being able to use the flashlight is in the specs. Several details about this new scanning functionality need to be formally announced, but I am positive the PowerApps team has listened to the remarks in the community. The PowerApps team aims at September to support Android devices. As can be read here, the PowerApps team is as we speak redesigning the functionality of scanning barcodes/QR codes, like using the native device’s API's for detecting barcodes/QR codes.Ībout two weeks ago, a new (experimental) feature targeted for iOS devices has been introduced which makes it possible to scan QR codes (and Data Matrix codes) too. Not being able to scan QR codes and certain limitations of the barcode scanner functionality, like the minimum size of a barcode, have limited the usage of the PowerApps mobile app as a scanner solution.
