Posted on by wpitre2000

Does anybody of a sample of how to open an external app using the Launch function? For example, if I want to open the "calc.exe", what would be the syntax? The tutorial shows to use the app ID, but I'm not sure how to get the app ID.

Thank you,

Wayne

Hello,

The launch function can be used to open either a web browser (if the parameter points to a website), or another app within the apps that you own in your PowerApps subscription. The format isn't very discoverable at this point (we're working to make it easier), but if you go to the web portal (https://web.powerapps.com), select "My Apps", and click any of your apps, it will launch the app in the web browser. In the browser URL, you will find the app id. For example, for this app:
The app id is "/providers/Microsoft.PowerApps/apps/087103e2-fa74-3dfc-3cb8-b4fab28e319a" (unescaping the '%2f' into '/'), and you can launch it from a button with a formula Launch("/providers/Microsoft.PowerApps/apps/087103e2-fa74-3dfc-3cb8-b4fab28e319a").

So ok I created a button that uses the Launch code.

EX: Launch("Http;// one drive link to open a excel file")

But the excel file can't open in office 365 excel app due to some formulas and protection i need it to open in the app users local excel program either windows base android or iphone. So how do i accomplish that please sir. Not many examples running around the web.

Hi @Jparker as mentioned in our other discussion, the link to the Excel file should open in the phone's browser.
At least in my case it opened correctly.

How about to open a PowerApps app, from Microsoft Flow?

e.g. Create a Flow which is: PowerApps button -> Push Notification "Something has changed!"

The user is prompted by a push notification that at the moment, has to come from the Microsoft Flow app. I'd like this to include a link to the PowerApps app for them to open it directly from the notification.

I've tried "%2fproviders%2fMicrosoft.PowerApps%2fapps%2f087103e2-fa74-3dfc-3cb8-b4fab28e319a" (substituting my app id for this one) but it didn't work.

The hyperlinks to PowerApps that work for me are in the form:
https://web.powerapps.com/apps/b6a27b52-xxxx-xxxx-xxxx-xxxxxxxxxx

Where does your type of link ("%2fproviders%2fMicrosoft.PowerApps%2fapps etc.") come form?

Thanks Meneghino, that link redirects me to the app.

I had taken the "%2fproviders%2fMicrosoft.PowerApps%2fapps etc." format from Carlos's explaination of what to pass the Launch() function (about 4 posts up).

Any idea if you can direct to a specific **screen** in the app?

hi @GeraintDavies
try the Param function, then you can try to redirect with an OnVisible on the landing screen

Hi @Sru
Have the link to open the app as something like this:
https://web.powerapps.com/apps/96062213-2c6b-a6ab-04d8-f0917e8af9b2?MyParam=123

Then within the app, use Param("MyParam") to use the value "123" to point to the desired record.

You can then point to the desired record for example by using Value(Param("MyParam")) in the Default property of a gallery.

Hope this helps.
