Using ctypes in python to access a C# dll's methods

阅读更多关于 Using ctypes in python to access a C# dll's methods

问题 I would like to implement C# code in a critical part of my python program to make it faster. It says (on Python documentation and this site) that you can load a Dynamic Link Library (and so say the PyDocs) as follows: cdll.LoadLibrary("your-dll-goes-here.dll") This is the part of my code that takes care of this feature: from ctypes import * z = [0.0,0.0] c = [LEFT+x*(RIGHT-LEFT)/self.size, UP+y*(DOWN-UP)/self.size] M = 2.0 iterator = cdll.LoadLibrary("RECERCATOOLS.dll") array_result =

问题 There were already a few similar questions on stackoverflow, but I haven't found the answer I have an application that consists of several tab pages. On one of them I'm loading a list of a few dozen user controls at a time. Currently I'm doing it in Load event and because of that I have a small delay before this page is loaded. What I want to do is to make UI more responsive and fill the list after the page is fully loaded. Is there any way to track when the user control has fully loaded it's

jQuery: How to check when all images in an array are loaded?

阅读更多关于 jQuery: How to check when all images in an array are loaded?

I have an array of images (the exact number of images varies), and when they all load I want some code to execute. I tried this but it doesn't work: myImgArray.load(function(){ alert('loaded'); }); I get 33: Uncaught TypeError: Object [object Object],[object Object],[object Object],[object Object] has no method 'load' I don't think a for loop or something similar would work because the images might, and probably will, load in 'random' order. The only way I know of to do it is to attach a load handler for each image and keep a count of how many have been loaded. When you reach your total, then

loading arrays saved using numpy.save in append mode

阅读更多关于 loading arrays saved using numpy.save in append mode

I save arrays using numpy.save() in append mode: f = open("try.npy", 'ab') sp.save(f,[1, 2, 3, 4, 5]) sp.save(f,[6, 7, 8, 9, 10]) f.close() Can I then load the data in LIFO mode? Namely, if I wish to now load the 6-10 array, do I need to load twice (use b): f = open("try.npy", 'r') a = sp.load(f) b = sp.load(f) f.close() or can I straightforward load the second appended save? I'm a little surprised that this sequential save and load works. I don't think it is documented (please correct me). But evidently each save is a self contained unit, and load reads to the end of that unit, as opposed to

best way to write jQuery's replaceWith() in natural JavaScript

阅读更多关于 best way to write jQuery's replaceWith() in natural JavaScript

问题 Having trouble with a function hitting the page as soon as possible, so i need to write it in pure javascript and include it in the head. not sure how to go about it, because as i understand it, by using .replace() the new element will be moved to a different location on the page. jQuery's replaceWith() behavior is ideal. $("#imagefiles").replaceWith("<input type='file' name='imagefiles' id='imagefiles' />"); 回答1: var image = document.getElementById('imagefiles'), parent = image.parentNode,

How to debug “Could not load file or assembly” runtime errors?

阅读更多关于 How to debug “Could not load file or assembly” runtime errors?

I have a project that uses a Java library converted using IKVM . I added the created DLL plus all possible IKVM DLLs as references to my project, but when I run it, I get the following runtime error: System.IO.FileNotFoundException : Could not load file or assembly 'core, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified. I'm not really sure how to debug this error. Is there a way to know exactly which type is missing? From the description I'd guess this is the generated DLL (from the Java lib) but I have properly added

问题 I have a jQuery ajax function that loads some content into a div, some of the content is images.
