progress-bar

问题 I am converting a .avi file to .flv file using ffmpeg. As it takes a long time to convert a file I would like to display a progress bar. Can someone please guide me on how to go about the same. I know that ffmpeg somehow has to output the progress in a text file and I have to read it using ajax calls. But how do I get ffmpeg to output the progress to the text file? Thank you very much. 回答1: I've been playing around with this for a few days. That "ffmpegprogress" thing helped, but it was very

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . I have searched this website to find progress bars, but the ones I have been able to found show animated circles that go to the full 100%.

问题 Hope someone can help. I have a simple scenario where clicking checkboxes is driving a progress bar in WPF. The checkboxes are contained in a UserControl and the Progress bar is in a simple WPF client window. On the user control I am using two dependency properties: 1) the existing Tag property has the value I wish to bind to the progress bar value and 2) a DP called CbCount which represents the total number of checkboxes. The problem: When the application runs the progress bar's progress

问题 I just about got this, but I have a small problem in the order of things going off. Specifically, in my thread() I am setting up an array that is used by a Spinner. Problem is the Spinner is all set and done basically before my thread() is finished, so it sets itself up with a null array. How do I associate the spinners ArrayAdapter with an array that is being loaded by another thread? I've cut the code down to what I think is necessary to understand the problem, but just let me know if more

问题 I have an asynctask that is in its own activity. I pass it a string value and it connects to my web service and downloads Json data based on the name I pass in, returning the Json resultset. Works great. I'd like to add a progress spinner to the asynctask, but I'm stymied as to how to do it. I've perused this and many other blogs, and come close but have not yet found the solution. It seems I either need to have the asynctask in with an Activity class to get the context or I have to pass in

问题 I'm trying to get the value for a progessbar(in C#) from a variable I currently have, divided by 52, and multiplied by 100. This is the code I have, any suggestions to fix it ? int value; value = TestP1.corAns / 52 * 100; ProgressBar pBar = new ProgressBar(); pBar.Value = value; label2.Text = Convert.ToString(value) + "%"; 回答1: Value is int variable and therefore TestP1.corAns / 52 will be rounded to some integer value even if TestP1.corAns is a real number ( float or double ). Moreover, if
