  • How to with extract url from tweet using Regular Expressions

    - by neutreno
    Ok so i'm executing the following line of code in javascript RegExp('(http:\/\/t.co\/)[a-zA-Z0-9\-\.]{8}').exec(tcont); where tcont is equal to some string like 'Test tweet to http://t.co/GXmaUyNL' (the content of a tweet obtained by jquery). However it is returning, in the case above for example, 'http://t.co/GXmaUyNL,http://t.co/'. This is frustracting because I want the url without the bit on the end - after and including the comma. Any ideas why this is appearing? Thanks

  • Copy/Paste in emacs ansi-term shell

    - by user130208
    I have configured my emacs to run zsh shell within ansi-term. However, copy/paste no longer works i.e. nothing is getting pasted from kill-ring to the terminal. Changing the TERM to vt100, or eterm doesn't solve the problem. Would appreciate any ideas or solution. Thanks Sandeep

  • Simulating inheritance with WF 4.0

    - by pablocastilla
    Hello everyone, I would like to achieve the following: all the workflows created should have the same structure (validation, execution, save results), and all the developers should implement those three stages (maybe leaving it empty). Similar to inheritance with abstract methods. Any ideas?

  • Checking an empty Core Data relationship (SQLite)

    - by rwat
    I have a to-many relationship in my data model, and I'd like to get all the objects that have no corresponding objects in the relationship. For example: Customer - Purchases I want to get all Customers that have 0 Purchases. I've read somewhere that I could use "Purchases[SIZE] = 0", but this gives me an unsupported function expression error, which I think means it doesn't work with a SQLite backing store (which I don't want to switch from, due to some performance constraints). Any ideas?

  • SQL: Get count of rows returned from a left join

    - by Rogue Coder
    I have two tables, one called calendars and one called events. There can be multiple calendars, and multiple events in a calendar. I want to select every calendar, also getting the number of events in the calendar. Right now I have : SELECT C.*, COUNT(*) AS events FROM `calendars` AS C LEFT JOIN `events` E ON C.ID=E.calendar GROUP BY C.ID But that doesn't work. Items with no events still return 1. Any ideas?

  • How to handle null return from custom HttpHandler in asp.net?

    - by Campos
    I'm using a custom ashx HttpHandler to retrieve gif images from a database and show it on a website - when the image exists, it works great. However, there are cases when the image will not exist, and I'd like to have the html table holding the image to become invisible so the "image not found" icon is not shown. But since the HttpHandler is not synchronous, all my attempts checking for image size at Page_Load were frustrated. Any ideas on how this can be accomplished?

  • How to create a named temporary file in memory?

    - by conradlee
    I would like to use Python's tempfile module to create a temporary file that I will use for communication between processes (use of pipes is awkward). The documentation I've linked to above shows two functions that almost do what I want: tempfile.NamedTemporaryFile # For creating named tempfiles tempfile.SpooledTemporaryFile # For creating tempfiles in memory but actually I want a tempfile that is both named AND in memory. Any ideas?

  • Silverlight Out of Browser (OOB) app crashing only on OS X

    - by BarrettJ
    We have a Silverlight application that runs OOB (out of browser) so the user can install it. When it's running OOB we display a button that calls Application.Current.MainWindow.Close() so that the user can exit the application. This works perfectly fine on windows, but causes an error saying the application has quit unexpectedly on OS X. Anyone have any ideas why this might be? Thanks!
