  • Does armcc optimizes non-volatile variables with -O0 ?

    - by Dor
    int* Register = 0x00FF0000; // Address of micro-seconds timer while(*Register != 0); Should I declare *Register as volatile while using armcc compiler and -O0 optimization ? In other words: Does -O0 optimization requires qualifying that sort of variables as volatile ? (which is probably required in -O2 optimization)

  • Using RegEx to Identify parts of a Database Connection String

    - by David_Jarrett
    I'm trying to get to grips with regular expressions: I have a database connection string and I'd like to use a regular expression to identify specific Keys and Values within it. For example server=foo;database=bar;uid=foo;pwd=bar I'd like something to return "database=bar;" using the 'database' key to identify it, ideally it would be case insensitive. I can do this using normal code, but I think that this is exactly the sort of thing for which regular expressions were designed.

  • Coldfusion - taking a Serialized String and converting it to a Structure

    - by nobosh
    I have the following serialized string from a nested sortable list: ul[0][id]=main1&ul[0][children][0][id]=child2&ul[0][children][0][class]=&ul[1][id]=main3&ul[2][id]=main4&ul[3][id]=main5 I want to be able to record this in the database, and think I need a structure to do this. What's the best way to turn this into a structure, so I can sort it in the database, and easily render the list on the page in the future. Thanks,B

  • How to reorder type members with Resharper?

    - by AngryHacker
    Typical scenario: a class that a lot of people have worked on. I'd like to sort methods, properties, etc... in alphabetical order. I'd like to be able to do this within the region or globally in the class. I see the feature in Resharper to do it, but it does not seem to do anything.

  • What LPR arguments do I need to print a 1400x800 pixel image on a 4x6 label?

    - by Nick
    This is driving me nuts. UPS sends our system a 1400x800 GIF image of a shipping label, which is supposed to fit nicely on a 4x6 page. Unfortunately, I can't seem to get the command line options right to make it happen. We're using an Eltron/Zebra 2844 with a network adapter, and printing from our Ubuntu 8.04 server using CUPS. We're using the correct drivers, and test pages print correctly. No matter what I try though, it insists on printing the UPS labels accross 6 pages, with a little bit of the label on each page, or way too small. I've tried a bazillion different lpr settings, most of them producing garbage. The closest I've gotten is this: lpr -P Eltron2844 -o natural-scaling=55 -o page-right=0 -o page-left=0 -o landscape -o media="4x6" ./1ZY437560399620027.gif but it causes the image to be too small on the page. It's about an inch too short, and there's a 1/2" margin on both sides. If I bump the scale up to 56, it explodes the image onto two pages, and squashes it. Any ideas?

  • Validating forms with regex in codeigniter

    - by Alex
    How can I validate a form using regex in codeiginiter. I'd like to check the input against: ^([0-1][0-9]|[2][0-3]):([0-5][0-9])$ I'm assuming the best way is in some sort of callback. I tried a bunch of ideas on the web but I can't seem to get any working.

  • Is there a simple automatic backup system for Visual Studio projects?

    - by Jelly Amma
    Hello, I'm using Visual Studio 2008 Express and I would like Visual Studio (or perhaps an Add-in) to save my whole project to some sort of auto-incrementing archive or whatever would help me recover from disasters. I don't have much need for SVN or complex versioning systems. I'm just looking for something simple and lean. Any help would be much appreciated. Jenny PS : I looked into the built-in AutoRecover feature but it doesn't seem to save more than a few files.

  • order array containing text and numbers

    - by ptrn
    I'm looking for the easiest way to sort an array that consists of numbers and text, and a combination of these. E.g. '123asd' '19asd' '12345asd' 'asd123' 'asd12' turns into '19asd' '123asd' '12345asd' 'asd12' 'asd123' This is going to be used in combination with the solution to another question I've asked here. The sorting function in itself works, what I need is a function that can say that that '19asd' is smaller than '123asd'. I'm writing this in JavaScript.

  • HTTP Proxy with monitor UI for local install

    - by zedoo
    Hi, I'm looking for an HTTP Proxy/GUI combination that should be installed locally on my Windows PC. The UI should display something similar to Firebugs "Network" tab, showing request/response headers and content as plaintext. It would be cool if I could attach requests to a sort of node for later comparison, similar to what you can do when using the Proxy that comes with JMeter.

  • Writing a Python extension in Go (golang)

    - by tehwalrus
    I currently use Cython to link C and Python, and get speedup in slow bits of python code. However, I'd like to use go routines to implement a really slow (and very parallelizable) bit of code, but it must be callable from python. (I've already seen this question) I'm (sort of) happy to go via C (or Cython) to set up data structures etc if necessary, but avoiding this extra layer would be good from a bug fix/avoidance point of view. What is the simplest way to do this without having to reinvent any wheels?

  • Using an ObjectCollection as a parameter create a new Control?

    - by Luis
    I was using something like public int Test(System.Windows.Forms.ListBox.ObjectCollection Colecction) { } With this I want to pass just the ObjectCollection of the control, to sort, add and delete elements without passing the entire control, but someone told me that, this way of calling the collection, actualy, create an entire ListBox, making it a worst decition, than, passing a ListBox as a parameter. Is it true? An if, what's the best way of working whit the collection?

  • Twitter feed only load periodically

    - by William
    I've tried many jQuery twitter feed plugins and they all seem to suffer from the same problem. Nothing loads for unless I refresh several times and then it will load once. I then need to refresh several more times before it loads again. Is there some sort of limitation on Twitters side or does this only happen to me? Example - This is the test site but it is basically ready to go live except for this issue.

  • Visual Studio support for coding in CIL/IL/MSIL?

    - by jdk
    For the longest time I've been curious to code in Intermediate Language just as an academic endeavour and to gain a better understanding of what's "happening under the hood". Is there any sort of Visual Studio support for this in the form of: project templates, IntelliSense integration, and those kind of RAD features?

  • How to create a project template for Ruby on Rails projects?

    - by wgpubs
    When I build Rails applications I find myself doing the same things over and over again. This includes adding the same gems/plugins, configuration info and custom initializers, rake tasks etc... etc.... This can't be a good thing. So, is there a way to package all this repetitive code into some sort of project template ... so that I can do a "rails myapp" and have everything good to go from there? Btw, running 2.3.5 if that matters :) thanks

  • License plate recognition

    - by WowtaH
    As a side-project I'm trying to create an app that scans license plates from passing cars from my living-room window. I have hooked up a high resolution camera to my system to capture (moving) images into my c# app. Now all I need is a way to interpret these images into something readable. I´m thinking about some sort of OCR-solution that is fast/accurate enough for moving images. Hope you can give me some direction!
