问题 Suppose you have 3 arrays you want to loop over, with lengths x, y, and z, and for each loop, you want to update a progress bar. For example: function run() { x = 100; y = 100; z = 10; count = 0; for (i=0; i<x; i++) { //some code for (j=0; j<y; j++) { // some code for (k=0; k<z; k++) { //some code $("#progressbar").reportprogress(100*++count/(x*y*z)); } } } } However, in this example, the progress bar doesn't update until the function completes. Therefore, I believe I need to use setTimeout

问题 Update: Got it working updated my working code Here is what I have so far private async void ZipIt(string src, string dest) { await Task.Run(() => { using (var zipFile = new ZipFile()) { // add content to zip here zipFile.AddDirectory(src); zipFile.SaveProgress += (o, args) => { var percentage = (int)(1.0d / args.TotalBytesToTransfer * args.BytesTransferred * 100.0d); // report your progress pbCurrentFile.Dispatcher.Invoke( System.Windows.Threading.DispatcherPriority.Normal, new Action(

问题 Currently, I have a button that when the user clicks on it, it looks for a specific CD-ROM drive that is ready and contains a file. Sometimes, when the user clicks on a button, the button click is mouse down and the program hangs for an indeterminate time until the computer reads the CD-ROM drive. I made my progress bar but I noticed a few things: 1) The program hangs/freezes before the method that checks the cd drives gets called. So I can't set the progress bar to display when the method is

问题 Yoyo experts! I have several progressbars on my Windowsform (NOT WPF), and I would like to use different colors for each one. How can I do this? I've googled , and found that I have to create my own control. But I have no clue , how to do this. Any idea? For example progressBar1 green, progressbar2 red. Edit: ohh, I would like to solve this, without removing the Application.EnableVisualStyles(); line, because it will screw my form looking up :/ 回答1: Yes, create your own. A rough draft to get

问题 I am try to bind parallel task to a listView that contains pprogressBars. I am using a limited scheduler that only allows specified maximum of parallel degree. So far it works OK most of the time but occasionally two tasks updates the same progress bar in the listView. Below is my code. Any idea how to prevent two tasks from updating the same progressbar in the listView? Or how to update the progress bar from tasks running concurrently? public class MyClass { public ObservableCollection

问题 I have been trying to understand how to add a progress bar, I can create one within the GUI I am implementing and get it to appear but even after checking through http://docs.oracle.com/javase/tutorial/uiswing/components/progress.html I am still no clearer on how I can set a method as a task so that I can create a progress bar for running a method. Please can someone try to explain this to me or post an example of a progress bar being used in the GUI with a task being set as a method. Thanks.

问题 in my python program to upload a file to the internet, im using a GTK progress bar to show the upload progress. But the problems that im facing is that the progress bar does not show any activity until the upload is complete, and then it abruptly indicates upload complete. im using pycurl to make the http requests...my question is - do i need to have a multi-threaded application to upload the file and simultaneously update the gui? or is there some other mistake that im making? Thanks in
