• django image managment

  - by Andrey

  I'am new in django. In my project I'am working with images. I don't know how to organize the management of images. I need to dynamically upload the pictures and resize them. First question - what is the best way to dynamically upload images with progress bar and without flash? I found this and this, but I believe there is a better way. Second question. I have to save one image in different sizes. I won't use these thumbnails on my pages, but another application will. Many clients could upload images at the same time. This means that I can not resize all the images at the same time. How should I organize this process? Is there are a better ready-to-use solution for image management issue?

• Can you Borrow a PDF?

  - by WeNeedAnswers

  What are the legalities of letting someone borrow a book that you have purchased that so happens to be in PDF format with no DRM? I know that I can lend a printed book to someone and this not infringe copyright, but a pdf? I know that the thought police are going to be on my case about "no one here is a legal expert" or the "question can't be answered" or "controversial", But I would like to have the opportunity to at least surface the issue, and allow people to comment. I am not looking for point scoring on this, or even an answer, but as stackoverflow has a rather large technical savvy audience that would appreciate the question I think that it could be the next hurdle that will stop technical progress.

• Repositioning a label with mouseevents to anywhere on the screen

  - by user2947295

  I've created a label and used setPixmap to attach a .png image to the label. I've also setWindowFlags to disable the title bar and create a frameless window. Because I've disabled those, it also disables the ability to drag anything around, so I want to create mouseevents (unless there's a better method) to position my label anywhere on the screen exactly like dragging the frame of a window. How would I do that? An example and brief explanation would be greatly appreciated.

• VS2010 constantly searching for something

  - by alekop

  Hi, Recently my VS has started doing a search through all project assemblies after a project is reloaded, or after I close a window following a Go to Definition command. It just says Searching in the status bar, and enumerates the assembly names. It's driving me nuts, because the process can take up to a minute, and it completely locks up the whole application while it's doing this. Has anyone else experienced this? Thanks, Aleko

• Using sed and/or awk, how can do a sed swap on all text in a file until I see a line matching a reg

  - by Ross Rogers

  How can I do a sed regex swap on all text that preceed a line matching a regex. e.g. How can I do a swap like this s/foo/bar/g for all text that precedes the first point this regex matches: m/baz/ I don't want to use positive/negative look ahead/behind in my sed regex, because those are really expensive operations on big files.

• CodeIgniter | direct Echo during working script

  - by Sep O Sep

  Is it possible to echo something while the script for example is still running in a loop? my problem: I ask the server with Ajax and then the server is fetching mails and store them in Database. This took around 15 sec. During that Time the Server should echo his progress so that the Javascript can update a loading bar. This is working with a php script without CodeIgniter well. Is there a way to skip the output class and all that stuff to get a direct echo? Thanks

• iPhone SDK: Downloading large files from a server into the app's documents.

  - by Jessica

  Hi, I am building an app that plays multiple video files, But I would like to know How do you download a video file (100mb - 300mb) from a server into the application's documents so it can later be locally referred to in code? The reason I want this type of a set up in my app is that I don't want the app binary to be made unnecessarily large due to including videos some users may not want. Also does this violate any of apple's terms? Also would it be simple to implement a progress view with this kind of set up and if so how? Any help is appreciated.

• Python: How should I make instance variables available?

  - by swisstony

  Suppose I have: class myclass: def __init__(self): self.foo = "bar" where the value of foo needs to be available to users of myclass. Is it OK to just read the value of foo directly from an instance of myclass? Should I add a get_foo method to myclass or perhaps add a foo property? What's the best practice here?

• Server Side code Pushing Data to client Browser while current thread is busy Comet (programming)

  - by h_power11

  Hello Friends, I am writing one simple web page with bunch of textboxes and a button control. Now when user finished editing the values on this text boxes user has to click the button and this button invoke heavily process intensive algorithm on server side code based on the data received from client (Textboxes) And it could some time takes up to 30 to 45 minutes to complete the whole operation so the current thread is still inside the button click event handler function. That background task only provides one event, and the web page subscribes to it to get some text data after each stage of processing I was wandering if there is any way I can keep user up-to-date with what is the current progress on that background task. I have div element to print the current status information So I am looking for some sort of reverse mechanism then "get" and "post". I have read some articles on the Comet (programming) but I can't find any easy or definitive answer Thanks in advance

• VS2010 patch: why it's take so much time to install it? [closed]

  - by Mendy

  Visual Studio 2010 RC has a few of patches release. For more information about them take a look here. What I'm expect from patch program, is to replace a few dll's of the program to a new fixed version of them. But when I run each of this 3 patches, they take a lot of time (5 minutes each), and you think that the program was frozen because the progress bar stay on the begging. This is question may not be so important, but it really interesting me to know, why this happens? It's really confusing to see that each VS2010 (or Microsoft in general) is frozen to 4-5 minutes.

• Should Javascript's "for in" construct iterate the length property?

  - by Eric

  I'm making a bookmarklet, but I've encountered some wierd behaviour in IE8. The code causing the problem is this: var els = document.getElementById("my_id").getElementsByTagName("*"); for(var i in els) { alert(i+","+els[i]) } The first thing that is alerted is "length, n". This isn't the case in chrome: just in IE8. Interestingly, it seems to behave differently depending on whether the code goes in the console/address bar or the page itself. Is this standard behaviour?

• Displaying Data on the Windows Form

  - by The.Anti.9

  I'm searching files and returning lines that include the search text, and I'm not really sure the best way to display the information I get. Every time I get a match, I want to show, in some sort of control, the File it came from, and the whole text line. (aka streamreader.ReadLine() result). First I tried just putting it all in a read-only text box, but it doesn't have a scroll bar. What is the best form control to help me display this data neatly?

• How to change the value of progressbar in C#?

  - by shekhar

  Hi, I want to add an progress bar into my C# based application. I would like to know what is the good way of updating its value at particular events? My problem is, I have single function in UI which does all the processing.This function in turn calls many more functions, creates objects, updates database, etc. (basically performs all the work) and returns values in an output file. I have access to that function only. So in this how to update the progressbar's value at the end of each step? What is the best practice for this kind of situation? What is the good way to keep UI logic and business logic seperate? I want to avoid writting progressbar related code in my library code. Please suggest some solution. Thanks and Regards,
