Answer : If you examine the item using PowerShell you can get a better idea of what is going on. In all the cases where I have seen it the lock expires after short period(20 minutes) and has been caused by word setting a lock when a user has selected to edit the file: $web = Get-SpWeb http://somesite.net $item = $web.GetListItem("/relative/url/to/item.doc") $item.file.LockType $item.file.LockedByUser $item.file.LockExpires If you are facing this error while deleting empty folder "The file is currently checked out or locked for editing by another user.", Then it might be because of there are documents in the library that don't have a major version published. Yo can go into the Library Settings and take ownership of the files. Then delete the entries, and the folder can be deleted. Library Tools > Library > Library Settings > Permissions and Management > Manage files which have no checked in version

Answer : As long as your application complies with the regulations of AppGallery, there should not be any problem it. https://developer.huawei.com/consumer/en/doc/30202 AppGallery does not have any restriction on the language application developed with, no need to worry about it; flutter, cordova, react.native, xamarin they are fine. Just a point to take care. If you are using SDKs or services those depend on Google Play services, when you have published your application on AppGallery, it will be visible only for Huawei devices supports Google Play Services. In theory, yes it could. Huawei uses an OS called Harmony OS. The Arc compiler in Harmony OS supports all the major programming languages including C/, C++, Java, JavaScript and Kotlin. Flutter compiles Dart code to native device code (Java, and Kotlin for Android and Swift for iOS). Huawei is making an Arc compiler that supposedly makes it easy to turn Android apps to Harmony OS apps. What does this mean for Flutt...

Answer : I hope this is helpful to anybody having trouble understanding computational time complexity for Breadth First Search a.k.a BFS. Queue graphTraversal.add(firstVertex); // This while loop will run V times, where V is total number of vertices in graph. while(graphTraversal.isEmpty == false) currentVertex = graphTraversal.getVertex(); // This while loop will run Eaj times, where Eaj is number of adjacent edges to current vertex. while(currentVertex.hasAdjacentVertices) graphTraversal.add(adjacentVertex); graphTraversal.remove(currentVertex); Time complexity is as follows: V * (O(1) + O(Eaj) + O(1)) V + V * Eaj + V 2V + E(total number of edges in graph) V + E I have tried to simplify the code and complexity computation but still if you have any questions let me know. Considering the following Graph we see how the time complexity is O(|V|+|E|) but not O(V*E). Adjacency List V E v0:{v1,v2} v1:{v3} v2:{v3} v3:{} Ope...

Answer : AndroidViewModel provides Application context If you need to use context inside your Viewmodel you should use AndroidViewModel (AVM), because it contains the application context. To retrieve the context call getApplication() , otherwise use the regular ViewModel (VM). AndroidViewModel has application context . We all know having static context instance is evil as it can cause memory leaks!! However, having static Application instance is not as bad as you might think because there is only one Application instance in the running application. Therefore, using and having Application instance in a specific class is not a problem in general. But, if an Application instance references them, it is a problem because of the reference cycle problem. See Also about Application Instance AndroidViewModel Problematic for unit tests AVM provides application context which is problematic for unit testing. Unit tests should not deal with any of the Android lifecycle, such as con...

Answer : Sure, You can set the src attribute on the source element: document.querySelector("#myVideoTag > source").src = "http://example.com/new_url.mp4" Or using jQuery instead of standard DOM methods: $("#myVideoTag > source").attr("src", "http://example.com/new_url.mp4"​​​​)​ Then you need to call the load method on the video element: videoElement.load() I have faced this problem several times and based on previous experience and digging I can suggest these options: replace video tag completely yes, just re-insert <video> element with new sources. It's straightforward, but effective approach. Don't forget to re-initialize event listeners. assign video URL to video.src this I saw a lot in answers here, on stackoverflow, and also in sources on github. var video = document.getElementById('#myVideo'); video.src = newSourceURL; It works, but you cannot provide browser opt...
