  • Passing arguments to a C program

    - by Radhika
    Hi All, I was writing a C program where I use 6 variables a,b,c,d,e,f a,b,c are constant values which I should pass as an argument(command line) d,e,f are going to be size of arrays(which are a part of a structure) typedef struct { blah blah } ex; ex ex0[d]; I am very confused about how to pass all these as argument. Right now I have hard coded these values,which apparently I should not be doing.

  • Does an XPathDocument load the whole xml document?

    - by Wires
    If I do XPathDocument doc = new XPathDocument("filename.xml"); Does that load the entire document into memory? I'm writing a mobile phone app and the document might store lots of data that doesn't ever need to all be loaded at the same time. Mobile phones don't usually have too much ram!

    Okay, I have a ViewController that has 12 UIButtons as instance variables, and they are created in interface builder. I want to access another variable in the viewController from the UIButton's init method. Is that possible? By the way, I'm writing in Objective-C in the iPhone SDK. Cheers.

  • How do i get direct Descendants with html agility pack

    - by acidzombie24
    I have a specific html node and i want to get the 2nd aka last direct descendant. So after writing .Descendants("div") i wrote ls.Last(). I actually got the last div in the 2nd descendant. Not what i am expecting. How do i get only the direct descendants? or how do i get the descendant with a specific classname? because "div.postBody" would be a suitable alternative.

  • ARM Simulator on Windows

    - by Betamoo
    I am studying ARM Processors from a textbook... I thought it will be more useful if I could apply what I learn on an ARM simulator... writing code then watching results and different execution stages would be more fun... I have searched for it, but all I could find was either a freeware on linux or a demo on windows Is there a simulator that allow me to see execution steps and different changes for ARM processor (any version!) that runs on windows?? Thanks

  • Update saved password for basic authentication using a script

    - by Kalamane
    I have a website that uses basic authentication as described on this webpage. Each of the computers I manage have the password saved in their browser. There is only one username and password for this. After someone logs in to the site this way, they are presented with their individual username and password prompt as part of the web page. The purpose of the initial username/password is to discourage non-technical employees that aren't supposed to be using the page from even viewing it. So far, when we've had to change this password, I've manually gone to each computer and updated the saved password. I'm writing a startup script to configure other aspects of these systems so that I can maintain them easier. I'd like to be able to update the saved password via this script. The operating system running on these machines is Windows XP SP3 and the browsers they're using to access this site are IE8 and IE9. How can I update the saved basic authentication information for a website via a script?

  • What are the benefits of learning a new language, as a game developer?

    - by Keand64
    I'm an independant game developer/designer, and I'm wondering what specific benefits are there to learning a new programming language. I do my programming in C++ currently, and I want to know if there are any tangible benefits to learning a different language, as in, benefits to writing a game x in language y versus game w in language z? Basically, I understand that learning a new programming language will help me think about a problem in different ways, but what are some actual benefits to using one language over another in specific scenarios?

  • regular expression for string in c

    - by darkie15
    Hi All, I am working writing a regular expression used to validate string in C. Here is to what I have gone so far '^"[A-Za-z0-9]*[\t\n]*"$' for rules - A string should begin with double quotes - May not contain a newline character However, I am not able to capture the rule for allowing '\' or '"' in a string if preceded with '\'. Here is what I tried: '^"[A-Za-z0-9]*[\t\n]*[\\\|\\"]?"$' But this doesn't seem to work. What might be wrong with the regular expression here? Regards, darkie15

  • Assembly Programming and Interrupt Handling

    - by nmr
    I'm writing a program in assembly using MIPS architecture for a class, and I'm having trouble figuring out how to grab an input character by a user and store it in a register to process. The program would open a console, output a message, the user can then input a character and then this determines what is supposed to happen next in the program. Like I said, I'm having trouble figuring out how to grab the character so that I can act upon it in the program. thanks

  • avoiding the tedium of optional parameters

    - by Kyle
    If I have a constructor with say 2 required parameters and 4 optional parameters, how can I avoid writing 16 constructors or even the 10 or so constructors I'd have to write if I used default parameters (which I don't like because it's poor self-documentation)? Are there any idioms or methods using templates I can use to make it less tedious? (And easier to maintain?)

  • How realistic/easy is it to host our own web servers?

    - by morpheous
    It is increasingly looking like we will need to host our own servers, because we need modems physically attached to the server machines. I (think) we will need a T1 line to our office for starters. Dont know what else is involved other than the obvious redundancy and failover requirements. My questions are: Do we really have to do it our selves or can we find a service that allows the modems to be remote as well? If we have to host the servers ourselves, what are the steps (technical and operational) required?

  • Copy an entity in Google App Engine datastore in Python

    - by Gordon Worley
    In a Python Google App Engine app I'm writing, I have an entity stored in the datastore that I need to retrieve, make an exact copy of it (with the exception of the key), and then put this entity back in. How should I do this? In particular, are there any caveats or tricks I need to be aware of when doing this so that I get a copy of the sort I expect and not something else.

  • Why is Perl commonly used as CGI scripts?

    - by Michael Vasquez
    I plan to add a better search feature to my site, so I thought that I would write it in C and use the CGI as a means to access it. But it seems that Perl is the most popular language when it comes to CGI-based stuff. Why is that? Wouldn't it be faster programmed in C or machine code? What advantages, if any, are there to writing it in a scripting language? Thanks.

  • C# - Exception messages in English?

    - by Carra
    We are logging any exceptions that happen in our system by writing the Exception.Message to a file. However, they are written in the culture of the client. And Turkish errors don't mean a lot to me. So how can we log any error messages in English without changing the users culture?
