This uses the Dropbox .NET SDK to download a file from the Dropbox API at the remote path to the local file "Test", while tracking progress: var response = await client.Files.DownloadAsync(path); ulong fileSize = response.Response.Size; const int bufferSize = 1024 * 1024; var buffer ...

You cannot pass a reference (or const reference) directly to a thread because std::thread will copy/move them. Instead, use std::reference_wrapper: void foo(int& b) { b = 10; } int a = 1; std::thread thread{ foo, std::ref(a) }; //'a' is now really passed as reference thread.join()...

To get info from the requesting url (notice that req is the request object in the handler function of routes). Consider this route definition /settings/:user_id and this particular example /settings/32135?field=name // get the full path req.originalUrl // => /settings/32135?field=name // get...

Reachability uses NSNotification messages to alert observers when the network state has changed. Your class will need to become an observer.

// Java: String joined = things.stream() .map(Object::toString) .collect(Collectors.joining(", ")); // Kotlin: val joined = things.joinToString() // ", " is used as separator, by default

// Java: Arrays.stream(new int[] {1, 2, 3}) .map(n -> 2 * n + 1) .average() .ifPresent(System.out::println); // 5.0 // Kotlin: arrayOf(1,2,3).map { 2 * it + 1}.average().apply(::println)

If you want to graph two series on one graph, you can use the Merge function. This can also be combined with the Series function to manipulate the Y axis (like forcing it to start at zero). template graph.template { subject = ... body = `{{template "header" .}} <stro...

This example uses the Dropbox .NET library to get a shared link for a file, either by creating a new one, or retrieving an existing one: SharedLinkMetadata sharedLinkMetadata; try { sharedLinkMetadata = await this.client.Sharing.CreateSharedLinkWithSettingsAsync (path); } catch (ApiException...
