• Make C# source run as a script?

  - by acidzombie24

  I am doing a little scripting and i find some more power would be nice. Like the ability to keep trying to delete a file with a 1sec delay AND have it portable since i spent some time today translating a bat script to bash. I know i can use php or python but i VERY MUCH PREFER static/compile time checking. Is there a way to run C# code as a script? I am hoping i dont have to create a custom ext and write a app to dynamically compile and execute the script (i know have source to compile .js somewhere...). Does anyone know of a solution?

• Implementing a live voting system

  - by Will Eddins

  I'm looking at implementing a live voting system on my website. The website provides a live stream, and I'd like to be able to prompt viewers to select an answer during a vote initiated by the caster. I can understand how to store the data in a mySQL database, and how to process the answers. However: How would I initially start the vote on the client-side and display it? Should a script be running every few seconds on the page, checking another page to see if a question is available for the user? Are there any existing examples of a real-time polling system such as what I'm looking at implementing?

• GoTo statements and alternatives in VB.NET

  - by qais

  I've posted a code snippet on another forum asking for help and people pointed out to me that using GoTo statements is very bad programming practice. I'm wondering: why is it bad? What alternatives to GoTo are there to use in VB.NET that would be considered generally more of a better practice? Consider this snippet below where the user has to input their date of birth. If the month/date/year are invalid or unrealistic(using if statements checking the integer inputs size, if there's a better way to do this, I'd appreciate if you could tell me that also :D) How would I be able to loop back to ask the user again? retryday: Console.WriteLine("Please enter the day you were born : ") day = Console.ReadLine If day > 31 Or day < 1 Then Console.WriteLine("Please enter a valid day") GoTo retryday End If

• Updates to Wordpress theme template/stylesheet are not reflected when a file is edited

  - by Bryan

  I am developing a theme in Wordpress. I have an issue where updates to my stylesheet (style.css) are not being reflected in the browser after FTPing a new version of the file to the server. Edits will only show up in the browser after waiting a long time, (15+ minutes). I have tried all the things mentioned here, which have not worked. These include: Making sure no caching plugins are installed in Wordpress Clearing the browser cache Trying from a different browser Making sure I am editing and accessing the correct file Checking webhost configuration panel for a caching plugin Something seems to be caching the stylesheet but I'm not sure how this might be so.

• Blob ID matching over multiple frames in C++ (image analysis)

  - by pollux

  Dear reader, I'm working on a blob matching and tracking library in C++. Currently I'm using openCV to detect blobs and try to match blobs in a new frame by checking the position, velocity and size of the blob. This works quite okay and I'm receiving a high blob match rate (95% or higher). Sometimes blobs fall out of the image or new blobs appear. Now I need to give matched blobs the same ID as they had before. I'm wondering if there are typical or commonly used techniques for doing this. Or even some keywords I can use to google on. Thanks

• How can I check a user/password combination on an ActiveDirectory without putting the password in a String?

  - by Jean Hominal

  I want to check User/Password combination on a Windows domain. Right now I do it with the following code: bool Login(String username, String password) { var principalContext = new PrincipalContext(ContextType.Domain); principalContext.ValidateCredentials(username, password); } While it works, the thing that bugs me is that I have to put the password in a String in order to use that API; as I am using a SecureString to store the password everywhere else, I would really like to use some way of checking the username / password combination without having to pass the password as a managed System.String. What would be the best way of achieving that?

• nUnit Assert.That(method,Throws.Exception) not catching exceptions

  - by JasonM

  Hi Everyone, Can someone tell me why this unit test that checks for exceptions fails? Obviously my real test is checking other code but I'm using Int32.Parse to show the issue. [Test] public void MyTest() { Assert.That(Int32.Parse("abc"), Throws.Exception.TypeOf<FormatException>()); } The test fails, giving this error. Obviously I'm trying to test for this exception and I think I'm missing something in my syntax. Error 1 TestCase '.MyTest' failed: System.FormatException : Input string was not in a correct format. at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal) at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info) at System.Int32.Parse(String s) based on the documentation at Throws Constraint (NUnit 2.5)

• C# move file as soon as it becomes available.

  - by m0s

  Hi, I need to accomplish the following task: Attempt to move a file. If file is locked schedule for moving as soon as it becomes available. I am using File.Move which is sufficient for my program. Now the problems are that: 1) I can't find a good way to check if the file I need to move is locked. I am catching System.IO.IOException but reading other posts around I discovered that the same exception may be thrown for different reasons as well. 2) Determining when the file gets unlocked. One way of doing this is probably using a timer/thread and checking the scheduled files lets say every 30 seconds and attempting to move them. But I hope there is a better way using FileSystemWatcher. This is a .net 3.5 winforms application. Any comments/suggestions are appreciated. Thanks for attention.

• JS DOM: Get elements by text content.

  - by hristo

  Hello! I am looking for a way to perform fulltext search on the DOM tree with JS. In two words, I would like to retrieve the list of text nodes which contain a given string. I've tried mootools' Element.getElements ( ':contains[string]' ) but I can't get it to work with strings containing whitespace. I'm thinking about simply indexing all text nodes and checking against each node for the string being searched for, but, in my project, there's no way of telling when the DOM updates in order to maintain such an index up-to-date. Any better ideas? Thanks

• SEO: It's recommended to upload and put live a beta / non-finished version of web site??

  - by Jonathan

  I'm working on this big website and I want to put it online before its fully finished... I'm working locally and the database is getting really big so I wanted to upload the website and continue to work on it in the server, but allowing people to enter, so I can test. The question is if this is good for SEO, I mean, there are a lot of things SEO related that are incomplete.. For example: there are no friendly URLs, no sitemap, no .htacces file, lot of 'in-construction' sections... Does Google will penalize me forever? How does it works? Google indexes adn get the structure of the site just once or its constantly updating and checking for changes??? What i should do? What you recommend?!!?

• Writing .NET in dynamic language?

  - by tillda

  I'm confused by the possibility of writing .NET in dynamic languages, such as (Iron)Ruby. Particularly, I've seen code in IronRuby that used generics (...foo[String]), but I'm not aware of this feature in Ruby as it seems nonsense to me in dynamic languages. So, when I write .NET app in IronRuby, how is it with type safety and compilation? I thought that it is just as dynamic as Ruby everywhere else. I thought that if the Ruby syntax is OK all the type checking would be done at the runtime. Also, as far as I know, .NET itself is type-oriented - there are classes that heavily utilize the mentioned generics. How is this handled? And what about delegates? In dynamic languages I can have almost function-spaghetti and sometimes, its just fine (like hacking UI in javascript). Or do I have to care even about generic delegates?

• Looking for alternatives to the database project.

  - by Dave

  I've a fairly large database project which contains nine databases and one database with a fairly large schema. This project takes a large amount of time to build and I'm about to pull my hair out. We'd like to keep our database source controlled, but having a hard getting the other devs to use the project and build the database project before checking in just because it takes so long to build. It is seriously crippling our work so I'm look for alternatives. Maybe something can be done with Redgate's SQL Compare? I think maybe the only drawback here is that it doesn't validate syntax? Anyone's thoughts/suggestions would be most appreciated.

• How can I check if a Perl array contains a particular value?

  - by Mel

  I am trying to figure out a way of checking for the existence of a value in an array without iterating through the array. I am reading a file for a parameter. I have a long list of parameters I do not want to deal with. I placed these unwanted parameters in an array @badparams. I want to read a new parameter and if it does not exist in @badparams, process it. If it does exist in @badparams, go to the next read.

• Data Usage Checker Tools

  - by Lucifer

  Hey All, I am about to begin a project for a new client, and am worried about a few things concerning data usage on their internet plan. We're in an area where most of the major networks don't cover the area, and the ones that do, have very expensive plans, with very low data allowance per month. I need to develop an app, but part of the problem lies with checking database values every 30 seconds. It's pretty important that this check is happening every 30 seconds, as the database is actually updated all day everyday, approx. every 5seconds (apparently). Each row in the database consists of about a page full of text if you were to paste it into MS Word. So, are there any logical ways of minimizing data usage in my case, and also how am I able to see exactly how much data is used just to establish a connection to the database? Are there any tools for this kind of info? Thanks :)

• Validating single form field with CodeIgniter

  - by iamdadude

  Is there a quick way to validate a single form field with CodeIgniter to see whether or not that field matches a set of rules? There's the $this-form_validation-run();, but that will return either TRUE or FALSE for the whole form, and that's just not what I'm looking for. For example, if I only wanted to check if the email was valid, checking the whole form is not going to get me the result I'm looking for. I looked through the documentation but couldn't find anything like $this-form_validation-run(); that accepts one parameter and returns TRUE or FALSE if it's valid.

• Please explain this php expression "!$variable"

  - by DogBot

  What does an exclamaton mark in front of a variable mean? And how is it being used in this piece of code? EDIT: From the answers so far I suspect that I also should mention that this code is in a function where one of the parameters is $mytype ....would this be a way of checking if $mytype was passed? - Thanks to all of the responders so far. $myclass = null; if ($mytype == null && ($PAGE->pagetype <> 'site-index' && $PAGE->pagetype <>'admin-index')) { return $myclass; } elseif ($mytype == null && ($PAGE->pagetype == 'site-index' || $PAGE->pagetype =='admin-index')) { $myclass = ' active_tree_node'; return $myclass; } elseif (!$mytype == null && ($PAGE->pagetype == 'site-index' || $PAGE->pagetype =='admin-index')) { return $myclass; }`

• PHP to C# and Vice versa

  - by Daniel Sh.

  I'm in this project: A web page that's gonna be used by the front-end company people to query and update data from a SQL DB. I'm working with visual studio and the code behind (C#) is almost done, so the interactions between SQL and C# and ok. My original idea was to work with ASP.NET which is familiar to me, but that's not gonna be possible. I have to switch to PHP. So, today is my first day learning PHP, checking http://php.net/manual/en/index.php and a lot of things seem quite similar to ASP.NET so I guess it won't be that hard. Anyways, some questions popped up quite fast as I wanted to script something else than a "hello world" . Is there an easy way to get/send C# variables from my class using a php page? I've read soemthing about using XML in order to do so, but still I'm scratching my head, is there another, easier, way to do this?

• I need a mechanism for locating SQL server instances

  - by SzamDev

  Hi I have an idea and I want to apply it to my Application (C# .NET). When we connect to a DB (MS SQL Server 2008) in VS 2008, the ConnectionString saved in the Application Setting and it's a static varriable (no one can edit it unless you edit it inside VS 2008). I want a way to let my Application search for MS SQL Server and save it to Application Setting and use it to connect to my DB Programmatically. When my application start, the first thing to do is checking the ConnectionString if vaild, NOT Empty and test connection to MS SQL Server Successfully so if there is a proplem I think to show a window form to let the user enter some data like username and password for MS SQL Server 2008 Is there any way to do it?

• PHP Security checklist (injection, sessions etc)

  - by NoviceCoding

  So what kind of things should a person using PHP and MySql be focused on to maximize security. Things I have done: -mysql_real_escape_string all inputs -validate all inputs after escaping em -Placed random alpha numerics before my table names -50character salt + Ripemd passwords Heres where I think I am slacking: -I know know nothing about sessions and securing them. How unsafe/safe is it if all you are doing is: session_start(); $_SESSION['login']= $login; and checking it with: session_start(); if(isset($_SESSION['login'])){ -I heard something about other forms of injection like cross site injection and what not... -And probably many other things I dont know about. Is there a "checklist"/Quicktut on making php secure? I dont even know what I should be worried about.I kinda regret now not building off cakephp since I am not a pro.

• C# Closing a form during a constructor

  - by pm_2

  Is it possible to close a form while the constructor is executing (or simply to stop it showing at this stage)? I have the following code: public partial class MyForm : Form { public MyForm() { if (MyFunc()) { this.Close(); } } } Which errors in Main(), here: static void Main() { ... // Following line errors Application.Run(new MyForm()); } I’ve tried checking the result of MyForm like this: static void Main() { ... MyForm frm = new MyForm(); if (frm != null) { // Following line errors Application.Run(frm); } } But that doesn’t seem to help. Can anyone tell me a way around this, please? Maybe a way to check the form to see if it still exists?

• Can Eclipse not hard-code ECLIPSE_HOME when exporting build.xml?

  - by stevex

  I have an Eclipse project that I'm attempting to set up to build both with Eclipse and externally with Ant. It seems like a good way to do this is to have Eclipse generate a build.xml file that I can then use with ant. I'd like to set it up so the build.xml can be regenerated from Eclipse whenever the need arises, which means no hand-editing the build.xml file. But Eclipse writes one entry in there that has a hard-coded path to a directory on my computer, which makes it unsuitable for checking in to a source repository. Specifically it's this entry that's the trouble: <property name="ECLIPSE_HOME" value="D:/Eclipse/Eclipse Galileo (3.5) SR1"/> Is there some way to have Eclipse not output this line, or to make it a relative reference or something that makes sense to check in?

• MSAccess Change Date Value Before Validation

  - by sisdog

  In a grid I have a date/time field where I would like the user to be able to type in short-hand formats for dates and times. For example, if they type in "435p" and then focus off of the cell they get the message "The value you entered isn't valid for this field.". Instead, I want to trap a pre-validationevent and change it to "4:35pm" for them. What event can I use? I've tried: LostFocus & BeforeUpdate: too late (validation fires before event) Dirty & OnChange: too early (they haven't left the cell yet) Or is there a way to turn off the native validation rule that is checking for date formats?

• Button to add value to array and then compare result with another array on IPhone.

  - by slickplaid

  I have ten buttons that each correspond to a different number. I'm looking to record the order that these buttons are pressed and enter them into an array and then compare it to another array that is static in the app. The check should be done on the Nth button press, where N equals the number of items in the other, static array. How do I A) have a button press add a value to an array B) stop after Nth button press equal to amount of numbers in the array I'm checking against and C) compare this array to the other array?

• PHP: How to check for response code?

  - by Tom

  Hi, I'm a relative PHP newbie implementing a PayPal IPN listener and all seems to be working fine, except I dont really know how to check for a response code. I've tried something ugly with cURL but it doesn't work at all (I'm not understanding cURL). I've tried this piece of code that I grabbed from somewhere on the net: $fp = fsockopen('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30); $response_headers = get_headers($fp); $response_code = (int)substr($headers[0], 9, 3); ... but it's not working (returns $response_code = 0). So right now, I'm debugging my IPN code without checking for a Response 200. Can anyone more experienced advise me on what's the proper/simple way to check this? Thanks
