  • What is a good standard for code width?

    - by BillyONeal
    Hello everyone :) I've heard in several places that it's bad to have code that is too wide onscreen. For example: for (std::vector<EnumServiceInformation>::const_iterator currentService = services.begin(); currentService != services.end(); currentService++) However, I've heard many arguments for 80 character wide limits. I'm assuming this 80 character limit comes from the traditional command prompt, which is typically 80 characters wide. However -- most of us are working on something much better than a typical command prompt, and I feel that using an 80 character limit encourages use of variable names that are far too short and do not describe what the variable is used for. What is a reasonable limit for a new project with no existing coding width standard?

  • How to Print the contents of a textbox in C++/CLI?

    - by Smoka
    I'm still learning C++ coding. I'm having troubles getting say ResultsBox-Text to printer successfully. What is the proper way to print in C++/CLI? I think im missing something simple. Ive tried multiple different routes/syntax's that ive read online/ in books. All of which got me to a dead end. Please even a rundown on the method of printing in any C based language might point me the right way. Thank you.

  • Can Fluent NHibernate be configured to use an arbitrary prefix on a property backing field?

    - by dommer
    I'm currently using a convention to (auto)map collection properties to backing fields in Fluent NHibernate. So, I map a property "Orders" to a field "_orders". The convention I'm using to do this is: public class HasManyAccessConvention : IHasManyConvention { public void Apply(IOneToManyCollectionInstance instance) { instance.Access.CamelCaseField(CamelCasePrefix.Underscore); } } Can I write a convention that maps a (collection) property to a field with a non-standard prefix (ignoring whether this is good coding practice for the present)? So, the property "Orders" would be mapped to "xyz_orders", for example. If so, how would I go about this?

  • Connecting PHP Server and Android?

    - by user3439988
    I am trying to create a simple test application to transfer data back and forth between my server and Android device. The following are the things I aim for: Ability to upload data and files to the server. To be able to view my files on the server. To be able to download the files from the server to my android device. Ability of the server to send me updates on the files or notifications to my phone. I need a safe and secure way to do these things. I have tried these: HTTPPost requests onto the server and echoing the output accordingly and capturing the HTTPresponse and parsing it. For files I have tried using MultipartEntity, but I think that has been deprecated.

  • Why are items being placed below?

    - by Adam DePolo
    This is really confusing and I have never had this occur. For my computer, it is fine. But for anyone else's computer I have tried, it screws up. So on my site, designatease.com , the second bar down, it places the fifth item down below the first four. I am not sure why it is doing this. I want them to span across the bar but the stop at about half way. Help me out SOF.

  • Which Subversion do I install for Windows?

    - by johnny
    I was reading this article on Coding Horror: http://www.codinghorror.com/blog/2008/04/setting-up-subversion-on-windows.html I went to the downloads and am confused. I would have just downloaded the first entry but I am afraid it would break my server or something if I don't have apache. We use IIS only and I wouldn't want to break it somehow. I don't even need a web or webdav front end. Which one should I install on this page, please: http://subversion.tigris.org/servlets/ProjectDocumentList?folderID=91 thank you for any help. edit: thanks for information, but I am hoping to stay free with the "regular" subversion. I plan on using TortoiseSVN for the client.

  • Problem with session based login after moving relevent files to site root

    - by YsoL8
    Hello I have a site which I have been testing in a sub-folder of my clients site-root. I had no log in problems during testing, but then I moved the new site files from a sub-directory to the main site root, and now I'm losing my logged in state after almost every page refresh in secure areas. I am running a $_session based login system that refreshes the session id on every page load, with a comparison value stored in the MySQL database. Does anyone have suggestions for what could be causing this problem?

  • Data Visualization Prototype (Java/Eclipse/DAO/Relational DB)

    - by Vince
    Hello, I am building a prototype application which displays various 2D & 3D data charts. I am using a third party library for the charts, the database and data extraction layer have already been coded. Can you advise on a good desktop Framework to use within Eclipse to provide a 'professional' looking GUI with minimum coding required (This is just a prototype). Further can anyone advise an effective method to port this application to a web server so users could access remotely? I have limited experience with GWT, are their more suitable alternatives? Many Thanks

  • MVC way of handling data input

    - by korki
    I have a data input module where I add the information of my product and its sub information like: product basic info product price info product price details price info and price details are related to product and are lists In my web forms approach I would store my main product object on the view state and I would populate it's pricing info and details while doing ajax postbacks. This way I can create a compact module that is very user friendly in terms of defining a lot of data from one place without the need to enter these data from seperate modules. And when I am done I would do one product.save() and that would persist all the data to the respective tables on db. Now I am building similar app on .net mvc framework and pondering on what would be the good way of handling this on mvc. I don't resonate towards storing all this on client side till I click save. And saving to the db after each action makes me remember the days I was coding on asp. Will appreciate your inputs on ways to approach this on mvc framework

  • Html newbie! background-image question

    - by Kevin Li
    Hi! I'm learning HTML and I wanted to practice by recreating a invoice sent to me by Electronics Expo. However, I used the background-image property and repeated it by repeat-x and now, the background stretches across the page so much that it has a horizontal bar to drag. http://htmlpocketreference.110mb.com/index.html You can see what I did in my link above. Also, I would really appreciate some advice on simplifying my CSS coding. It seems really messy and I have to move every element once something changes. -.- Thanks!

  • Maintaining stored procedures in source control

    - by dub
    How do you guys maintain your stored procedures? I'd like to keep versions of them for a few different reasons. I also will be setting up cruisecontrol.net and nant this weekend to automate builds. I was thinking about coding something that would generate the create scripts for all tables/sprocs/udf/xml schemas in my development database. Then it would take those scripts and update them in source control every couple hours.... Ideally, I'd like to make this some sort of plugin/module for cruisecontrol.net. Any other ideas?

  • Remembering Form information

    - by Pete Herbert Penito
    Hi everyone! I'm sorry if this has been asked before but I feel my situation is a little different... I have a huge form (like 50 questions involving checkboxes, drop downs, text boxes and textareas) When a user submits a form and the validation page throws an error, is there an easy way to keep the info they entered? My intitial form is on form.php and then the form action is form_posted.php, before anything is run on form_posted.php I have my validation code which sends the user back to form.php with an error number (eg. form.php?error=3) if there was a problem with any in particular. This is done with header("form.php?error=3") so on form.php do the posted variables exist? even tho the page wasn't specifically sent with any posted variables. Also if this is the case, is it completely secure to be making the value of a textbox what it was before? like <input type="text" value="php echo $_POSTED["username"] ?>">

  • Securing input of private / protected methods?

    - by ts
    Hello, normally, all sane developers are trying to secure input of all public methods (casting to proper types, validating, sanitizing etc.) My question is: are you in your code validating also parameters passed to protected / private methods? In my opinion it is not necessary, if you securize properly parameters of public methods and return values from outside (other classes, db, user input etc...). But I am constantly facing frameworks and apps (ie. prestashop to name one) where validation is often repeated in method call, in method body and once again for securize returned value - which, I think, is creating performace overhead and is also a sign of bad design.

  • Default datetime format in mySQL

    - by Davuz
    I'm coding to search data by compare datetime. In web form, user input value '2012-06-04' store in $_REQUEST['dateSearch']. I create datetime object from that: $dateObj = date_create_from_format("Y-m-d",$_REQUEST['dateSearch']); $dateParam = $dateObj->format("Y-m"); Then I use $dateParam in sql query to find data $sql = " SELECT * FROM `temp` as `t` WHERE `t`.`date` LIKE '$dateParam%' "; Everything is ok, but I'm not sure mySQL alway use only one datetime format "Y-m-d H:i:s". At here, $dateParam = $dateObj->format("Y-m"); I set default format is "Y-m". Is the default format never change? I don't want hard set format "Y-m-d H:i:s" in code, instead of, I think get format string from system to use is better. How do I get default datetime format string from mySQL???

  • How much effort does it take to spoof an Ip Address in a call to a webservice?

    - by Rory Becker
    I don't want to know how... Just how complicated.... I'm thinking of securing a webservice or 2 based on the incoming client ipaddress of the caller. Is this in any way secure? Surely if the IPaddress was being spoofed then the result would have to be sent back to the address that was being spoofed and therefore not reach the spoofer? Update: Ok so from what I can tell.... I should create a Gettoken() method which checks the IPaddress and passes out a cryptographically significant token with a timeout to any valid IP address. This is then required by any other method before any kind of side effect is allowed. Since an Attacker can't (likely) get the token without having a valid IP, he will be unable to validly call any of my "dangerous" webmethods ?

  • Is it legal for a C++ reference to be NULL?

    - by BCS
    A while back I ran into a bug the looked something like this: void fn(int &i) { printf(&i == NULL ? "NULL\n" : "!NULL\n"); } int main() { int i; int *ip = NULL; fn(i); // prints !NULL fn(*ip); // prints NULL return 0; } More recently, I ran into this comment about C++ references: [References arguments make] it clear, unlike with pointers, that NULL is not a possible value. But, as show above, NULL is a possible value. So where is the error? In the language spec? (Unlikely.) Is the compiler in error for allowing that? Is that coding guide in error (or a little ambiguous)? Or am I just wandering into the minefield known as undefined behavior?

  • Windows Server 2003

    - by user229133
    I have a website that is using Windows Server 2003. The site is called https://mysite.com/ and at ip address 111.1.1.1. Now when I log into the site all my relative links that are generated using NavURL (<%# NavURL("Images/Menu/img.gif")%) are saying "http://111.1.1.1/Images/Menu/img.gif" instead of "https://mysite.com/Images/Menu/img.gif". This is causing an error because it needs to be secure. I'm sure there is a setting on the server somewhere to point to the name and not the ip, but I don't know where. Thanks for your help.

  • Is Microsoft CCR gaining any traction?

    - by spender
    Microsoft's Concurrency and Coordination Runtime quite literally saved a project that was running into major issues with deadlocking. Since then I find that I use it more and more frequently for almost anything that requires asynchronous coding producing results that run lighter and faster than before. I can honestly state that it has transformed the way I think about multithread/multicore dev. Despite my personal love for CCR, there appears to be very little buzz surrounding it on the web and was wondering if anyone can offer any reason for this. Are there better alternatives, or is it a lack of promotion from MS, or are people simply happy with the existing tools?

  • Use .htaccess to limit access to file downloads

    - by jimiyash
    I have downloads for static files like product.exe. I want to limit access to these files with a .htaccess file so that only certain users can download it. I think this can be handled with mod_rewrite and I found this snippet online that blocks bad sites using the referrer. RewriteEngine on # Options +FollowSymlinks RewriteCond %{HTTP_REFERER} http://example.com/downloads/confirm/3811 [NC,OR] RewriteRule .* - [F] Source: http://www.javascriptkit.com/howto/htaccess14.shtml Instead of blocking based on referrer, I want to allow based on referrer. That way, the referrer can be a URL that cannot be accessed without first logging in. I am thinking about going this route and using the http referrer to give permission to the file. I know it may not be the best way to do it, and I guess the referrer can be spoofed, but it does not have to be THAT secure. I am also open to other ideas you may have to for limitting access. Please

  • Python wrapper for Google Maps making Google App Engine crash?

    - by user1679332
    I am currently trying to build a web app using Google App Engine that will involve using the Google Maps API. Since I am coding in python, I tried importing the python wrapper for Google Maps (found here); however, performing the import will cause my web app to crash. Are there any suggestions for how I can fix this problem? I'm guessing the crash might have something to do with the fact that I need to incorporate the google maps python wrapper into my application, but how do I go about doing that? Thanks!

  • How would you measure conversion for an iPhone App Download?

    - by Eran Kampf
    I want to test how users convert from my web page to downloading my iPhone app. Right now the best funnel I figured out was to go through a page that pings Google Analytics and then redirects to an iTunes link. But this funnel only measures conversion for users who got redirected to iTunes and not if they actually downloaded the app once they saw it in iTunes. Anyone knows of a way to measure conversion to the actual download? (I know this is not a coding question but still a problem a app developers would encounter trying to market their app)

  • C#: Basic Reflection Class

    - by Mike
    I'm trying to find a basic reflection abstract class that will generate basic information about a class. I have a template of how I would like it to work: class ThreeList<string,Type,T> { string Name {get; set;} Type Type {get; set;} T Value {get; set;} } abstract class Reflect<T> { List<ThreeList<string, Type, T> list; ReturnType MethodName() { foreach (System.Reflection.PropertyInfo prop in this.GetType().GetProperties()) { object value = prop.GetValue(this, new object[] { }); list.Add(prop.Name, prop.DeclaringType, value); } } } I'd like it to be infinitely deep, recursively calling Reflect. Something like this has to exist. I'm not really opposed to coding it myself, I just don't want to go through the hassle if its already been done.
