由 不打扰是莪最后的温柔 提交于 2019-12-12 13:14:45
问题 The page about the PubNub History API states that The history() function returns a list of up to 100 messages, the start time token and the ending time token. Is there a way to retrieve more than the 100 messages? I'm currently not a paying customer of PubNub. 回答1: PubNub Load History More than 100 Messages Sometimes you want to slice back in time over a linear stream of data. And often you'll want to do this at different levels of granularity. That is why PubNub Storage and Playback APIs

putc needs stdout, vs puts

由 微笑、不失礼 提交于 2019-12-12 12:07:12
问题 C history question here. Why does the C function putc require a second parameter like putc( 'c', stdout ) ; While puts is oh so more convenient puts( "a string" ) ; There is a function in msvc++ putchar( 'c' ) ; Which works the way one might expect putc to work. I thought the second parameter of putc was to be able to direct putc to a file, but there is a function fputc for that. 回答1: int putc ( int character, FILE * stream ); Writes a character to the stream and advances the position

How to limit HtmlUnit's history size?

由 て烟熏妆下的殇ゞ 提交于 2019-12-12 11:18:32
问题 I'm using HtmlUnit for a parsing job and I've discovered that the memory gets wasted with the WebClient holding the history for each WebWindow. I don't use the history at all and I'd like to disable its management or at least limit its size with 1 or 2. Is that possible? 回答1: The following code will set ignoreNewPages_ to true: try { final WebClient webClient = getWebClient(); final List<WebWindow> webWindows = webClient.getWebWindows(); History window = webWindows.get(0).getHistory(); Field

Android - nuke the previous app history

问题 Here's scenario. Say I have an app that I was using and navigated from activity to activity so now there's some history there. Then I switched to another app so my first one is on the background. If I return to it I would be able to click "Back" to navigate the history and traverse 1st app steps. Now imagine that I also have a notification that when clicked will bring one of the activities of the first app. Currently when that happens and I hit "Back" I will return to the previous history

ios open call history

由 会有一股神秘感。 提交于 2019-12-12 02:56:02
问题 How to open the call history programmatically? Sort of: call://history ? 回答1: You CANNOT do this because there is no available API for doing so and no custom URL ever for opening it directly into that app. So it is NOT possible sorry. I'd also say if you even found a way to do this it would be rejected under: 2.5 Apps that use non-public APIs will be rejected because you'd have to use a non-public API to do this. 来源： https://stackoverflow.com/questions/31002583/ios-open-call-history

jquery history back button to reset

由 ↘锁芯ラ 提交于 2019-12-12 02:46:51
问题 I am having a problem with my website. I have some animations when a redirect is happening to get a transition effect from page to page. The problem is that if a user clicks the Browsers Back button it goes to the previous page but it does not reset the animations so everything stays hidden as when you exited the page. To have a demo of the error go to http://www.econtentsys.gr/affiliate/xenosk/temp/amigdalos/main.php , Click on About Me and then click on your browsers (history) Back button.
