![]() ![]() For simple web deconstruction and just fooling around, this seems like a good app. But there is a OS 9 version! The few sites I tried did pretty well, but I didn't try more dynamic It will not follow JavaScripted links, or many other files that coders might obfuscate for ![]() I got all the HTML, CSS, XML, images, SWF's,Įven the favicon file. Will save all the related files for a URL into a folder on your computer. The icons are confusing, but no more so than Plucker, which I use to pull pages onto my WristPDA. SiteSucker is a very small app (less thanġ MB), and does one thing terrifically well: save all files and pages off a site. To reverse-engineer some poor web designer's brilliant CSS and use it yourself, that PDF save won't get you there. And if you're like me, completely unafraid However, the limits are you can't get theĪctual HTML, CSS, images, or other media files that actually make the site. I have weeded out several issues using this design pattern.Yeah, I have grown accustomed to saving web pages as PDF's.īetween Spotlight support (probably the only time I use it really) and just the cool factor of having a mostly-universalįormat for pages of info to carry around, the Save As PDF feature is terrific. For this circumstance I can use the flag in the constructor to disable the requirement.īy adding the Exception it forces the issue forward when I accidentally or neglectfully try to create the collection on the wrong thread and I find that the synchronization issues go away. Once in a great while I may need to create the collection while not on a UI thread (can't think of a reason right now but I added it just in case). RetVal = await MainThread.InvokeOnMainThreadAsync(() => Where TCollection : MYObservableCollection, new() When I need to create a collection when NOT on a UI thread I can do something along the lines of the following: public virtual async Task GetCollection() Public static void CollectionSyncCallBack( collection, object context, Action accessMethod, bool writeAccess) (this, SharedTools.LockingObj, callback) You should consider creating this collection on the UI Thread.", this.GetType())) Creating this collection on the NON UI Thread will result in a collection that is not synchronized with the UI. Throw new Exception(string.Format("MYObservableCollection: created on a non UI Thread. Protected virtual void CheckForUIThread(CollectionSynchronizationCallback callback, bool createOnNonUIThread) Public MYObservableCollection(CollectionSynchronizationCallback callback, bool createOnNonUIThread) : base()ĬheckForUIThread(callback, createOnNonUIThread) Public MYObservableCollection(CollectionSynchronizationCallback callback) : this(callback, false) ![]() public class MYObservableCollection : ObservableCollectionĬollectionSynchronizationCallback callback = CollectionSyncCallBack If it is not on the UI thread it will throw an exception. To ensure that the collection is created on the UI thread I inherit a class from ObservableCollection which checks for the UI Thread in its constructor (Using Xamarin.Essentials here). Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '- loaded the GameView nib but the view outlet was not set. Not sure if it matters anymore but I have found more reliable and consistent results by following these two simple rules:ġ) Create the collection on the UI thread, Make sure of this.Ģ) Synchronize the collection using a EnableCollectionSynchronization callback Var forms = await FormsDataStore.GetB圜reatorAsync(userName) Īfter clearing my binding object, i created a new temp ObservableCollection object to hold the new value and then add it to the binding object after. Task loadLineItems = Task.Run(async () => Because ObservableCollection is not thread safe and list bind to your list view, you shouldn't be adding value to the collection in a task. Public TransfersView(TransfersViewModel model) public partial class TransfersView : ContentPage ![]() The number of rows contained in an existing section after the update (130) must be equal to the number of rows contained in that section before the update (0), plus or minus the number of rows inserted or deleted from that section (1 inserted, 0 deleted) and plus or minus the number of rows moved into or out of that section (0 moved in, 0 moved out). Name: NSInternalInconsistencyException Reason: Invalid update: invalid number of rows in section 0. It works on both Windows Phone and Android but when running it on iOS I get an exception. I trying to bind a ListView with an ObservableCollection. ![]()
