  • C array initialization.

    - by chrisdew
    Why does static char *opcode_str[] = { "DATA" , "DATA_REQUEST_ACK" , "ACK_TIMER_EXPIRED" , "ACK_UNEXPECTED_SEQ" , "ACK_AS_REQUESTED" } ; work, but static char **opcode_str = { "DATA" , "DATA_REQUEST_ACK" , "ACK_TIMER_EXPIRED" , "ACK_UNEXPECTED_SEQ" , "ACK_AS_REQUESTED" } ; fails with SEGV when opcode_str[0] is printf'd? I think it's because the second listing has not allocated memory for the five element array of pointers, but I need a more comprehensive explanation. All the best, Chris.

  • Ruby does 'elseif' still exist

    - by catchmikey
    I'm just learning ROR and I came across the if / else statements. I also came across 'elseif' but my text editor (textmate) doesn't pick it up as a keyword, not does the program run properly. if name == 'Chris' puts 'What a lovely name.' elseif name == 'Katy' puts 'What a lovely name!' end I'm using the book, Learn to Program, which was written several years ago. I was wondering if the 'elseif' was changed because when I simply use 'else' it seems to function properly

  • Use reflection to get a list of static classes

    - by Christian
    Hi, many questions are close, but none answers my problem... How do I use reflection in C# 3.5 to get all classes which are static from an assembly. I already get all Types defined, but there is no IsStatic property. Counting 0 constructors is really slow and did not work either. Any tips or a line of code? :-) Chris

  • rake gems:refresh_specs error on unpacked gems

    - by Urf
    Following the great advice of Chris Wanstrath, I decided to vendor everything. However, whenever I run a rake task now I get an error for each of my unpacked gems stating config.gem: Unpacked gem gemname in vendor/gems has no specification file. Run 'rake gems:refresh_specs' to fix this. I've done this but no dice. Anyone have the same issue? If so, how do I resolve? TIA

  • How can I reload a datagrid in flash action script, after an xml file has loaded

    - by optician
    Hi Everyone, Does anyone know how to change the rowcount of a datagrid in flash after it has been created on the stage. I am loading an xml file externally that contains the number of rows the datagrid should have, but the problem is that becuase this file is not loaded at runtime, it just picks the default 3 items. Maybe I have to reload the datagrid on the stage, or loop until it is defined. Does anyone have experince of this. Regards, Chris

  • Flex: Change line height of Label component

    - by ChrisInCambo
    Hi guys, Maybe I'm googling for the wrong thing but I can't find anything on this. How can I change the line height of a Label element in Flex? I have two labels in a VBox and there is quite a lot of white space between them which I would like to reduce. There's no line height property and setting the height property causes overlap. Thanks in advance for any help! Cheers, Chris

  • Visual Studio highlighting source code in bold

    - by widgisoft
    While editing HTML/ASPX/ASCX etc; whenever I select an html tag, visual studio highlights the entire tag in black and bold; the black I'm not so fussed about but the bold changes the length of the line and really messes up the formatting. Is there a way to disable this? Thanks, Chris

  • What's the best way to identify subdomains by PHP dynamically?

    - by kavoir.com
    I have configured the wildcard DNS of *.mydomain.com and it's all working properly. My question is which of these should I rely on identifying client subdomain requests? $_SERVER["HTTP_HOST"] $_SERVER["SERVER_NAME"] $_SERVER["SCRIPT_URI"] They all seem to contain the subdomain part I want but after reading this article by Chris: http://shiflett.org/blog/2005/feb/more-on-filtering-input-and-escaping-output, I'm lost at see and there appears to be no safe way to do this? Any idea on accomplishing this task securely?

  • Reading and writing dates to the registry for trial version purposes.

    - by LeeW
    Hi all, Here's what I want to do, I want to store the date the first time the program is installed and also store a date when was the program was last run. I want the code to check to see if it was more than 30 days since the installation so I can turn off features. I also want to check if the system date is less than the last opened date and if so write the installed date to 1/1/1901 to prevent the program from running. Keeping in mind that this is not a consumer program but a business program I don't expect hackers to crack it, they may do but that is fine I simply want to give potential customers a reason to consider purchasing the program and the end of the trial will prompt this. 1: Does this sound reasonable? 2: How should I hide the fact this is a date so it's not easily changed? Many thanks Lee

  • How to do an alphnumeric sort in R

    - by cbare
    Is there an alphanumeric sort for R? Say I had a character vector like so: > seq.names <- c('abc21', 'abc2', 'abc1', 'abc01', 'abc4', 'abc201', '1b', '1a') I'd like to sort it aphanumerically, so I get back this: c('1a', '1b', 'abc1', 'abc01', 'abc2', 'abc4', 'abc21', 'abc201') Does this exist somewhere, or should I start coding? Thanks, -chris

  • Generating pagination links

    - by alpheus
    I am trying to implement a paging system that displays nearby page numbers as well as pages at each extreme. For example, if the user is on page 20 of 40, the following links should be displayed: 1, 2 ... 18, 19, [20], 21, 22 ... 39, 40. The solution would be similar to the one described here: http://90poe.com/alex-lee-on-bell-curve-pagination I have seen code to do this in PHP, but not in ASP.net (ideally I am looking for C# code). If anyone has done anything like this previously, it would be very helpful to see your code.

  • Can a webflow's action state have multiple redirects on success?

    - by callie16
    Say, I have this type of webflow: def myFlow = { state1 { } on("next").to("stateAct") stateAct { action { ... DB stuff ... } } on("success").to("state2") state2 { } on("prev").to("state1") } Now, the contents of "stateAct" is common between state1 and state2. Meaning, if I press "next" from state1, I need to pass by stateAct before I can go to state2 (which is the current implementation) and if I press "prev" in state2, I need it to pass by stateAct before it goes to state1. Obviously, in the sample webflow above, it doesn't do the latter. So, my question is, is there a way to detect in stateAct who called it (state1 or state2) so that I can redirect accordingly on "success"? Or something similar to that behavior? Thanks! -Lee

  • Automated incremental backups from Plesk on Centos to Amazon S3

Many thanks, Chris

  • How to create many div's with 100% height?

    - by ChrisBenyamin
    I need a html document, that contains multiple div's with 100% height (screen filling) one below the other. I have tried to apply every element a height of 100%, but that won't work seamless nor clean. Maybe there is a option with JavaScript? I don't have an idea. Please suggest me your solutions. chris
