Problem with Univeral app 8.1 (10) share charm and screenshot

Hello,

I'm trying to share a screenshot of my end game through the share charm of the universall app.

So I'm able right now to share text via the datatransfer manager like explained here :
https://msdn.microsoft.com/en-us/library/windows/apps/xaml/hh871368.aspx?f=255&MSPPError=-2147217396

But I'm unable to share an image with that.

I first use the Application.CaptureScreenshot("screen.png"). After that, I try to reload it in a storagefile, convert it in a RandomAccessStreamReference to use it with the SetBitmap.

But I always have an error. Since I move to Win10+VS2015, I'm unable to see the c# in visual studio so I don't have the error.

Has somebody done this before and can share his method?

Thank you in advance.

Karim

 

Yes, sorry for that. I forgot to copy that before coming to work. I will put my code as soon as I come home.

Maybe a I misunderstood. But when you build your universal app and check the C# option, you can open your project in VS and see the C# files?

 

Here is my code.

First I use the capturescreenshot

Code (CSharp):

1. Application.CaptureScreenshot("background.png");

And after, the user click a buton to share it

Code (CSharp):

1. public void ShareButton()
2.     {
3.         UnityEngine.WSA.Application.InvokeOnUIThread(() =>
4.         {
5.            
6. #if NETFX_CORE
7.                 DataTransferManager dataTransferManager = DataTransferManager.GetForCurrentView();
8.                 dataTransferManager.DataRequested += new TypedEventHandler<DataTransferManager, DataRequestedEventArgs>(this.DataRequested);
9.  
10.                 Windows.ApplicationModel.DataTransfer.DataTransferManager.ShowShareUI();
11. #endif
12.         }, false);
13.  
14.     }
15.  
16. #if NETFX_CORE
17.     private async void DataRequested(DataTransferManager sender, DataRequestedEventArgs e)
18.     {
19.     try{
20.         DataRequest request = e.Request;
21.         request.Data.Properties.Title = "My highscore in Cemetery Rush";
22.         request.Data.Properties.Description = "An example of how to share text.";
23.         request.Data.SetText("Woop woop");
24.  
25.         Windows.Storage.StorageFile sampleFile = await ApplicationData.Current.LocalFolder.GetFileAsync("background.png");
26.        
27.        
28.         request.Data.SetBitmap(RandomAccessStreamReference.CreateFromFile(sampleFile));
29.     }
30.     catch (Exception ex)
31.     {
32.       Debug.Log(ex.Message);
33.     }
34.     }
35.  
36.  
37. #endif

The code share all the text but not the image

 

Thank you Tomas for the advice.

Windows.Directory is not a Win store name space.

But I tried with

Code (CSharp):

1. Application.CaptureScreenshot(Path.Combine(ApplicationData.Current.LocalFolder.Path, "background.png"));

to save, and I still use

Code (CSharp):

1.  Windows.Storage.StorageFile sampleFile = await ApplicationData.Current.LocalFolder.GetFileAsync("background.png");
2.        
3.         request.Data.SetBitmap(RandomAccessStreamReference.CreateFromFile(sampleFile));

to open it.

But it's still not working.

 

Tomas,

I don't have any error.
I just display the path of where the screenshot is saved and what I get for the sampleFile.

The screen is saved at

and it's open after. The sampleFile path is

Sorry I didn't do the test before. So the file with this configuration, is open. But not display in Facebook, mail or Twitter.

 

What did you do to fix it?

The file exist because I open it with getfileasync.

 

Ok, that's weird.

I have no error. Every thing go well. It's just that I don't have the image after the share.

I'm away on vacation for a week. Will try a dummy project when I come back. Thanks for your help.

 

Ok, I did a simple test.

I tested it on Windows 10 (Universal app 8.1) and it worked.

So the bug is only on Windows phone 8.1.

 

Hy There,

I can share the image by email, but if I tried using Skype, I've got only the text .. (And the share UI does not show FaceBook ..)

Any idea ?
