Timer firing Tick event with 15 milliseconds delay

阅读更多关于 Timer firing Tick event with 15 milliseconds delay

问题 I'm having a weird problem with timers. As long as I know, the interval property of a timer indicates the delay between loops in which the timer_Tick event will be fired. I had this problem with the exact signature (15 and 16 milliseconds delay) before while programming in Visual Basic. Any timers that I create, fire their tick event with 15 or 16 milliseconds delay. For instance, if I set the interval of my timer to 1 (which means its tick event should get fired 1000 times in 1 second), the

问题 Hi Again Masters Of The Web :) Now, I have got a new stupid question, and I am asking to forgive me. I read everywhere about this solution, but didn't find the one that works for me.

问题 I'm working on an JavaFX 8 app right now, where i have a tableView and some textFields above which make it possible to search/filter for certain columns in the tableView. I have added a listener to the textFields, to trigger the filtering automatically when a change is detected. I used the code below to do this. textField_filterAddress.textProperty().addListener((observable, oldValue, newValue) -> { doSomething(); // in this case, filter table data and refresh tableView afterwards }); My

问题 I don't know exactly how to word a search for this.. so I haven't had any luck finding anything.. :S I need to implement a time delay in C. for example I want to do some stuff, then wait say 1 minute, then continue on doing stuff. Did that make sense? Can anyone help me out? 回答1: In standard C (C99), you can use time() to do this, something like: #include <time.h> : void waitFor (unsigned int secs) { unsigned int retTime = time(0) + secs; // Get finishing time. while (time(0) < retTime); //

Timing Delays in VBA

问题 I would like a 1 second delay in my code. Below is the code I am trying to make this delay. I think it polls the date and time off the operating system and waits until the times match. I am having an issue with the delay. I think it does not poll the time when it matches the wait time and it just sits there and freezes up. It only freezes up about 5% of the time I run the code. I was wondering about Application.Wait and if there is a way to check if the polled time is greater than the wait

问题 Now, I'm using my offline map osmdroid MapQuest (.zip file). However, the delay action time is not very good. Like: Map View Initialiation Time, Action Zoom Time ... Are there some solution to improve its performance? (like unzip .zip file or something else?) Thanks. 回答1: You stand a lot better chance with something like the GEMF format that is explicitly designed for the job at hand rather than ZIP. For big files it's way better. It is what I recommend for my users. 来源： https://stackoverflow

Asking a user for input only for a limited amount of time in python [duplicate]

阅读更多关于 Asking a user for input only for a limited amount of time in python [duplicate]

This question already has answers here : Keyboard input with timeout? (11 answers) Closed 4 years ago . The program I am working on needs to pause and ask the user for input and if there is none, move on with the program. I think it would look something like this: import time ...[code to run before break]... if input in time.sleep(5): [break out of normal code] else: [return to normal code] [code to run after break]... Any thoughts? EDIT: Didn't think about this when I asked but I am running Windows (8.1). Bit of a quick-and-dirty hack, but effective. The following waits for user input for 5
