I want to fetch a pptx from web and then grab the speaker notes of each slide. Is there an API that allows me to that?
Google Slides already provides that in their API here: https://developers.google.com/slides/api/reference/rest/v1/presentations/get
For powerpoint I've seen they have Javascript API, but it seems just for add-ins. Other option I've seen seems to be OpenXML SDK. Wondered what is the preferred approach?
If you deal with open XML documents only (*.pptx) you can use the Open XML SDK, see Welcome to the Open XML SDK 2.5 for Office for more information.
OfficeJS is for web add-ins only and not designed for standalone applications.
Aspose.Slides makes it easy to get speaker notes from a presentation. This library can be used in C#, Java, C++ and Python. The following C# code example shows you how to get the speaker notes from each slide:
using var presentation = new Presentation("example.pptx");
foreach (var slide in presentation.Slides)
{
// Get notes from the slide.
var slideNotes = slide.NotesSlideManager.NotesSlide.NotesTextFrame.Text;
Console.WriteLine(slideNotes);
}
This is a paid product, but you can get a temporary license to evaluate all its features. Alternatively, you can use Aspose.Slides Cloud SDK that provides REST-based APIs in many languages. The C# code example below shows you how to do the same using Aspose.Slides Cloud:
var slidesApi = new SlidesApi("my_client_key", "my_client_secret");
// A presentation saved in storage.
var fileName = "example.pptx";
var slideCount = slidesApi.GetSlides(fileName).SlideList.Count;
for (var slideNumber = 1; slideNumber <= slideCount; slideNumber++)
{
// Get notes from the slide.
var notesSlide = slidesApi.GetNotesSlide(fileName, slideNumber);
Console.WriteLine(notesSlide.Text);
}
This is also a paid product, but you can make 150 free API calls per month for your purposes. I work as a Support Developer at Aspose.

I am developing a Bot using Microsoft Bot Framework. I am using Adaptive Cards for displaying flights to users but they have a lot of limitations on their appearance. I am trying to render the adaptive card from one of the dialogs within my bot framework by creating a adaptive card renderer using my own hostconfig.json and then attaching the Html of my adaptive card back to the chat window. But its not working :(
public static Attachment CreateFlight(Flight flight)
{
var renderedAdaptiveCard = AdaptiveCardRenderer
.RenderCard(new AdaptiveCard
{
Body = new List<AdaptiveElement>
{
new AdaptiveContainer {Items = CreateFlightAdaptiveElements(flight)}
},
Actions = new List<AdaptiveAction>
{
new AdaptiveShowCardAction
{
Card = new AdaptiveCard
{
Body = new List<AdaptiveElement>
{
},
Actions = new List<AdaptiveAction>
{
new AdaptiveSubmitAction
{
Title = "Select",
Data = flight.Segments.Select(x => $"{x.Airline} {x.FlightNo}")
.Aggregate((i, j) => i + "/" + j),
}
},
BackgroundImage = new Uri($"{DomainUrl}/Images/ac_background.jpg")
},
Title = "Select"
},
},
BackgroundImage = new Uri($"{DomainUrl}/Images/ECEFF1.png")
});
var attachment = new Attachment
{
ContentType = "application/html",
Content = renderedAdaptiveCard.Html
};
return attachment;
}
Am I trying something that is impossible here ? How to change the default grey looks of my bot ? My primary channels would be Skype, Slack etc so I don't have plans to integrate this to a Web Chat. Kindly help me with this regard.
The idea behind Adaptive Cards is to allow each channel to render the cards in a way that's specific to that channel. A card "adapts" to any environment that might support it. While Adaptive Cards offer a lot of flexibility, the bot can only do so much because it's ultimately the channel that's in charge of rendering the card.
Card Authors describe their content as a simple JSON object. That
content can then be rendered natively inside a Host Application,
automatically adapting to the look and feel of the Host.
For example, Contoso Bot can author an Adaptive Card through the Bot
Framework, and when delivered to Skype, it will look and feel like a
Skype card. When that same payload is sent to Microsoft Teams, it will
look and feel like Microsoft Teams. As more host apps start to support
Adaptive Cards, that same payload will automatically light up inside
these applications, yet still feel entirely native to the app.
Users win because everything feels familiar. Host apps win because
they control the user experience. And Card Authors win because their
content gets broader reach without any additional work.
As you probably know, the RenderedAdaptiveCard type is meant to be used in client-side code. That means it can help you if you want to make your own channel for example, but it's not really meant to be used in a bot. Your code isn't working because there is no HTML attachment type and most channels don't support HTML at all. You can find more information in this question and this GitHub issue.
Hopefully you can achieve the appearance you're looking for using the tools available to you, such as images and links.
I am utilizing Syncfusion's PdfViewerControl and PdfLoadedDocument classes to generate thumbnail images of a PDF. However, once I moved the project to an Azure App Service, the PdfViewerControl is throwing an exception when being initialized. I am curious if it is attempting to use system memory and Azure is blocking this. Below is the method GenerateThumbnails I've created and the exception is being thrown when creating a new PdfViewerControl. If anyone has a work around for this or has experienced something similar when moving to Azure, any assistance would be greatly appreciated.
Along with that, if someone knows of another tool to create thumbnails from a PDF in this manner that'd be very helpful as well. Thanks!
Exception:
System.AccessViolationException: 'Attempted to read or write protected memory. This is often an indication that other memory is corrupt.'
Method:
public static List<Byte[]> GenerateThumbnails(Byte[] file)
{
Int32 resizedHeight;
Int32 resizedWidth;
List<Byte[]> thumbnails = new List<Byte[]>();
using (PdfViewerControl pdfViewerControl = new PdfViewerControl())
using (PdfLoadedDocument pdfLoadedDocument = new PdfLoadedDocument(file, true))
{
// The PDF Viewer Control must load the PDF from a PdfLoadedDocument, rather than directly from the filename because
// when loaded from the filename, it is not disposed correctly and causes a file lock.
pdfViewerControl.Load(pdfLoadedDocument);
for (Int32 i = 0; i < pdfViewerControl.PageCount; ++i)
{
using (Bitmap originalBitmap = pdfViewerControl.ExportAsImage(i))
{
if (pdfViewerControl.LoadedDocument.Pages[i].Size.Width > pdfViewerControl.LoadedDocument.Pages[i].Size.Height)
{
resizedHeight = (PdfUtility.TARGET_THUMBNAIL_WIDTH_LANDSCAPE * originalBitmap.Height) / originalBitmap.Width;
resizedWidth = PdfUtility.TARGET_THUMBNAIL_WIDTH_LANDSCAPE;
}
else
{
resizedHeight = PdfUtility.TARGET_THUMBNAIL_HEIGHT_PORTRAIT;
resizedWidth = (PdfUtility.TARGET_THUMBNAIL_HEIGHT_PORTRAIT * originalBitmap.Width) / originalBitmap.Height;
}
using (Bitmap resizedBitmap = new Bitmap(originalBitmap, new Size(resizedWidth, resizedHeight)))
using (MemoryStream memoryStream = new MemoryStream())
{
resizedBitmap.Save(memoryStream, ImageFormat.Jpeg);
thumbnails.Add(memoryStream.ToArray());
}
}
}
}
return thumbnails;
}
Update
Web App for Containers on Windows is now supported. This allows you to bring your own docker container that runs outside of the sandbox, so the restrictions described below won't affect your application.
There are restrictions in the sandbox that the app is running in that prevents certain API calls.
Here is a list of frameworks and scenarios that have been found to be
not be usable due to one or more of the restrictions above. It's
conceivable that some will be supported in the future as the sandbox
evolves.
PDF generators failing due to restriction mentioned above:
Syncfusion Siberix Spire.PDF The following PDF generators are
supported:
SQL Reporting framework: requires the site to run in Basic or higher
(note that this currently does not work in Functions apps in
Consumptions mode) EVOPDF: See
http://www.evopdf.com/azure-html-to-pdf-converter.aspx for vendor
solution Telerik reporting: requires the site to run in Basic or
higher. More info here Rotativa / wkhtmltopdf: requires the site to
run in Basic or higher. NReco PdfGenerator (wkhtmltopdf): requires
subscription plan Basic or higher Known issue for all PDF generators
based on wkhtmltopdf or phantomjs: custom fonts are not rendered
(system-installed font is used instead) because of sandbox GDI API
limitations that present even in VM-based Azure Apps plans (Basic or
higher).
Other scenarios that are not supported:
PhantomJS/Selenium: tries to connect to local address, and also uses
GDI+.

How can i using internal database for example (sqlite) for offline app in nativescript without using any plugin.
i'm searched every were how i can installed or used sqlite or other internal database for nativescript but i didn't have any answer.
Just like you would do with any code that you need to access the native APIs
e.g. (JavaScript) Android example
var query = "select sqlite_version() AS sqlite_version";
var db = android.database.sqlite.SQLiteDatabase.openOrCreateDatabase(":memory:", null);
var cursor = db.rawQuery(query, null);
var sqliteVersion = "";
if (cursor.moveToNext()) {
sqliteVersion = cursor.getString(0);
console.log(sqliteVersion);
}
The API references for SQLite in Android here and that said you can now follow a basic Android database tutorial and implement it step by step in your NativeScript application using JavaScript or TypeScript
Still, the plugin could provide all that wrapped in a ready-to-go functionality so unless you are lacking something it will be easier to use the nativescript-sqlite and avoid writing native code for Android and then for iOS.
I'm targetting iOS and Android platforms for a messaging application.
I want to use voice and messaging features of the sdk.
Are there any bindings available for sinch sdk for xamarin?
Sinch has a C# wrapper for sending SMS via their REST interface. It is available via a Nuget (Sinch.SMS) and/or you can grab the code on Github; https://github.com/sinch/Sinch.SMS
i.e. (from their hello world example):
To send an SMS use:
var client = new Sinch.SMS.Client("yourkey", "yoursecret");
var messageid = await client.SendSMS("+46722223355", "hello from sinch");
To check a status of an SMS use:
var client = new Sinch.SMS.Client("yourkey", "yoursecret");
var result = await client.CheckStatus(messageid);
As far as a complete SDK bindings for their Android/iOS SDKs, I do not know of one personally.
I 'just' would import them into XStudio and convert their sample call apps and give it a try. Should not take very long to see if the auto-wrappers work. Otherwise you would have manually correct/write the C# bindings to their 'native' lib
Here are some Xamarin binding libraries available on nuget. They are by a Vietnamese Software Development company called NAXAM. I believe these are all open source, and published on their github here: https://github.com/NAXAM
https://www.nuget.org/packages/Naxam.SinchVoice.Droid/
https://www.nuget.org/packages/Naxam.SinchVoice.iOS/3.11.0-pre1
https://www.nuget.org/packages/Naxam.SinchVerification.Droid/

I'd like to know, how can I use facebook c# sdk to post to user's wall from my wp7 app as application.
So I want to display message from FB application on users wall.
I have so far:
var app = new FacebookApp();
var parameters = new Dictionary<string, object>
{
{"access_token", accessToken},
{"appId", appId,
{"message", "TEST"}
};
var fbCB = new FacebookAsyncCallback(postResult);
app.PostAsync("me/feed", parameters, fbCB);
But this displays text on my wall as I wrote it, not like the application specified by appId.
app.PostAsync("friendId/feed", parameters, fbCB);
I would also suggest you to use the latest facebook c# sdk.
