delay

问题 I'm working with the the Release Candidate of Visual Studio 2010 using Wf4 to write a new workflow for approving resource requests. In my workflow, I would like for a request to expire after a few days if no approval has been made for the request. We did this in WF 3.5 (Visual Studio 2008) by adding a Delay timer into an EventDrivenActivity parallel to the EventDrivenActivity that was awaiting an approver to come and approve the request. If the Delay expired before an approval was made, the

问题 I have question about the Java threads. Here is my scenario: I have a thread calling a method that could take while. The thread keeps itself on that method until I get the result. If I send another request to that method in the same way, now there are two threads running (provided the first did not return the result yet). But I want to give the priority to the last thread and don't want to get the results from the previously started threads. So how could I get rid of earlier threads when I do

问题 Ran across the following problem in bxslider- how can you apply different delays between slides in the auto show? 回答1: I came up with the following solution which I will show here: in the jquery.bxslider.js replace: el.startAuto = function(preventControlUpdate){ // if an interval already exists, disregard call if(slider.interval) return; // create an interval slider.interval = setInterval(function(){ slider.settings.autoDirection == 'next' ? el.goToNextSlide() : el.goToPrevSlide(); }, slider

问题 I want to run a function every 5 minutes and have it synced with the clock. If I use time.sleep(60*5), the time starts to drift because my function adds a tiny bit of processing time. Is this a good way of running my function synced with the clock or is there a better way in python? def run(condition): def task(): #run data here pass runOnce = True while condition: if dt.datetime.now().minute % 5 == 0 and dt.datetime.now().second == 0 and runOnce: runOnce = False task() elif dt.datetime.now()

问题 Basically, I have an array of buttons I want to iterate and highlight (among other things) one after another, with a delay in-between. Seems like an easy task, but I can't seem to manage to get it to work cleanly while still being responsive. I started out with this: for MyButton *button in buttons { [button highlight]; [button doStuff]; usleep(800000); // Wait 800 milliseconds. } But it is unresponsive, so I tried using the run loop instead. void delayWithRunLoop(NSTimeInterval interval) {

问题 I hoped that the answers to squeezemylime's question would solve my problem as I also have a UIAlertView without text field but it did not work out well. Instead of a text field I placed a UIActivityIndicatorView animating on it and no buttons used on creation. So the alert gets programmatically dismissed so that the delegate method destroys the spinner on the alert and the alert itself (which has been retained through the time running). So, I'm getting also these wait_fences: messages within

问题 I'm looking for php code that changes file name -adds current date, and starts download the file with delay. If download will not start there is an option to download the file with added date by clicking the link. Something like this: Your download will begin in a few moments... If nothing happens, click <a href="">here</a> . I found only this: // It will be called downloaded.pdf header('Content-Disposition: attachment; filename="downloaded.pdf"'); // The PDF source is in original.pdf

问题 Following this question here on stackoverflow, I created a twitter bootstrap popover that loads on hover. However, the delay is not used, the popover just shows immediately. Here's my code: $('body').delegate('.withajaxpopover', 'hover', function(event) { if (event.type === 'mouseenter') { var el=$(this); $.get(el.attr('data-load'), function(d) { el.popover({delay: { show: 750, hide: 100 }, title: "MyTitle", content: d}).popover('show', {delay: { show: 750, hide: 100 }}); }); } else { $(this)
