  • How Do I Convert Pipe Delimited to Comma Delimited with Escaping

    - by Russ Bradberry
    Hi, I am fairly new to scala and I have the need to convert a string that is pipe delimited to one that is comma delimited, with the values wrapped in quotes and any quotes escaped by "\" in c# i would probably do this like this string st = "\"" + oldStr.Replace("\"", "\\\\\"").Replace("|", "\",\"") + "\"" I haven't validated that actually works but that is the basic idea behind what I am trying to do. Is there a way to do this easily in scala?

  • Custom keys with NERDComment plugin and remapped Leader?

    - by Paul Wicks
    I'm trying to set up the NERDComment plugin in vim, but I'm having some trouble with the keys. I'd like to set the basic toggle functionality (comment a line if it's uncommented, uncomment if it's commented) to be c. The problem is that I've remapped the Leader to be ,, which is the same key that NERD wants for all of it's hotkeys. Anyone have any idea as to how to set this up?

  • To jQuery or not to jQuery?

    - by pws5068
    I rather enjoy adding practical eye-candy to the networking community I've been developing but as things start to stack up I worry about load times. Is it truly faster to have users load (a hopefully cached) copy of jquery from Google's repositories? Does using jQuery for AJAX calls improve/reduce efficiency over basic javascript xmlHTTP requests? Is there a practical way to cut down the number of included scripts? For example, I include jQuery and jQuery UI from google, table sorter, and a growl plug-in.

  • Any good tutorials on using OAuth with Piston?

    - by Hank Gay
    I've looked at the relevant section of the Piston documentation, but it only seems to focus on how to turn it on, not what it would look like for clients or how to test it to verify it's working. The example only seems to use HTTP Basic and curl. Finally, Ned Batchelder's question makes it look like a tutorial is in order. Thanks.

  • Use web interface to modify htaccess file

    - by justinl
    The solution to a previous question (How to implement “Maintenance Mode” on already established website), was to use a modified .htaccess to deny IP addresses. What is the best way to use a web interface to modify an .htaccess file? What I want is a way for an admin to log in to the admin area and switch Maintenance Mode on and off using a basic html form. I'm using PHP and I'm already using an .htaccess file for a handful of ReWriting.

  • code formatter for grails and Groovy?

    - by Jared
    I'm currently using a basic text editor to write my grails code. Does anyone know of a program that will automatically format code with indentation similar to indent does for C? I'd rather use a commandline program to do this but can use an IDE to format my code if that's the only option.

  • Monitor USB optical mouse activity for movement and call a program on Windows

    - by CheeseConQueso
    I'm essentially looking to monitor a USB port input for whatever happens when the optical mouse detects its own movement and turns itself on. These mice usually have a dim red light when in "standby" mode and then the red light becomes brighter once you start moving it around. I want to use Visual Basic or something else native to the Windows environment to open an exe file or play a wav sound or call a bat file when the mouse "wakes up". Any suggestions or pushes in the right direction are appreciated.

    In Visual Studio debug mode it's possible to hover over variables to show their value and then right-click to "Copy", "Copy Expression" or "Copy Value".

  • Writing a DBMS in Python

    - by Matt Luongo
    Hey guys, I'm working on a basic DBMS as a pet project and planning to prototype in Python. I figure there's a reason there are only a few Python databases, and my gut agrees that my favorite language will be too slow to act as an honest performing database, but I'm looking forward to using it to learn what I need quickly. Would someone please contradict me? Is Python as ill-suited right now for this sort of thing as I think?

Canceling the child window and the parent text is highlighted. Anybody know how I can do this?

  • += new EventHandler(Method) vs += Method

    - by mafutrct
    There are two basic ways to subscribe to an event: SomeEvent += new EventHandler<ArgType> (MyHandlerMethod); SomeEvent += MyHandlerMethod; What is the difference, and when should I chose one over the other? Edit: If it is the same, then why does VS default to the long version, cluttering the code? That makes no sense at all to me.
