resume

问题 Any idea what are the best practices for archiving an NSViewController inside a window for resume (user interface preservation) purposes? I've tried archiving it in the window controller's encodeRestorableStateWithCoder: methods only to find out that the view controller doesn't get unarchived when restoreStateWithCoder: is called. // NSWindowController subclass -(void)encodeRestorableStateWithCoder:(NSCoder *)coder { [super encodeRestorableStateWithCoder:coder]; NSViewController*

问题 I know, there are several questions of this type but I tried all of it and it still doesn't work. Ok, for my app; I've got an Activity. In this Activity, there are 4 Tabs, and the fourth one contents a list and a record button. When I am pushing record, there is a GPS Listener which starts. After getting a new gps value, it pushes it into the list. This works so far! If I click the Home Button it still works, if I longpress it then. It resumes that Activity with the specific Tab open and the

问题 I'm writing a program to download/upload a file between a client and server using socket programming. The code i've written till now works in the sense that i can sucesfully transfer files. However , if a connection fails due to problem in the network/client/server while a download / upload is occuring.. i need to RESUME the download/upload from the original point(Do not want the originally sent data to be resent).

问题 I need to create a thread in Delphi with the following characteristics: Waits until the main thread adds data to a shared queue. Processes all the data in the queue, returning the results to main thread (for this last part I'll just send messages to the main window). Processing is time-consuming, so new data may be added to the queue while the worker thread is processing previous entries. Resumes waiting, using as little cpu cycles as possible. I cannot send messages to the thread, since it

问题 I'm trying to use http classes to pause/resume a download and pausing is easy by using the cancellation token , however how can i resume a download? I have used the background downloader class and it had a lot of issues in resuming and had many other issues to handle downloads. Here is my code: using Windows.Web.Http; using Windows.Web.Http.Filters; private async void Foo(StorageFolder folder, string fileName) { Uri uri = new Uri("http://localhost"); var filter = new HttpBaseProtocolFilter();

问题 When an app have been put into the background and later resumes to an activity, is it possible that static class variables set in another Activity could have been reset by the garbage collector and have got the value set to zero? I use a couple of public static int variables in my main Activity and use them as global variables in various other Activities. I have received a crash report in the developer console from Android Market where the only explanation I can find is that the app resumes

问题 I have already checked Tools > Options > General > Error Trapping in VBE - I have set it to both "Break in Class Module" and "Break on Unhandled Errors" and either way it still throws the error. The error is thrown on the line: Set xlContacts = Workbooks(LocalContactsFilename) It throws an error saying the subscript is out of range, and I understand that this means the index was not found within the Workbooks collection, this statement is here because usually the file is already open as an

问题 So my idea is have a special bullet that freezes the enemies, and after a period of time the enemies unfreeze itself and continue with their actions/animations. Here's a simple version of what I did: -(void)update:(ccTime)dt { CCSprite *enemySprite; CCARRAY_FOREACH(enemies, enemySprite) { if (CGRectIntersectsRect(_bullet.boundingBox, enemySprite.boundingBox)) { _bullet.visible = NO; [enemySprite pauseSchedulerAndActions]; enemySprite.pausingDuration = CACurrentMediaTime() +5; } if
