  • Synchronous HTTP Client with .NET sockets

    - by Ray Wits
    Does anyone know of any open source C# projects or some sample code that implement a synchronous HTTP client using sockets? I'm working on a project where I need a HTTP client using sockets. It can't use WebRequest or WebClient, nor can it use Asynchronous sockets. Don't ask. Also it would ideally be on .NET 2.0, yeah very cutting edge here. I figured the web would have tons of samples for this but suprisingly I couldn't find any. Probably because everyone is fortunate enough to use the built in APIs. If I don't find something I'll have to write it myself, which I don't really want to have to reinvent that wheel.

  • Is there a pre-made Continuous Integration solution for .NET applications?

    - by Brett Rigby
    From my perspective, we're constructing our own 'flavour' of NAnt/Ivy/CruiseControl.Net in-house and can't help but get the feeling that other dev shops are doing exactly the same work, but then everybody is finding out the same problems and pitfalls with it. I'm not complaining about NAnt, Ivy or CruiseControl at all, as they've been brilliant in helping our team of developers become more sure of the quality of their code, but it just seems strange that these tools are very popular, yet we're all re-inventing the CI-wheel. Is there a pre-made solution for building .Net applications, using the tools mentioned above?

  • Free PHP framework/library for single-sign on / cross domain login

    - by Dennis Cheung
    I am looking for free (non GPL is better) SSO framework/library implementation or code samples. There are many kind of SSO implementation. Sharing cookie, sharing session, one time token, associative accounts, etc, etc. (BTW, any good article compare them?) Is there any keyword I should google and reuse before before I start to implement our own wheel. I know OpenID, but which is too much and it is not our need. We rather keep it KISS. We just want share the credentials of user that could save users from another login form.

  • Implementing zoom on a fixed point, javascript/canvas

    - by csiz
    I want to implement zooming on the mouse pointer with the mouse wheel. That is scaling the image while the point under the mouse pointer stays fixed. Here is my code, which doesn't work very well var scala = 1 + event.wheelDelta / 1000; canvas.context.translate(-canvas.mouse.x * ( scala - 1 ) / canvas.scale,-canvas.mouse.y * ( scala - 1 ) / canvas.scale); canvas.context.scale(scala,scala); canvas.scale *= scala; //canvas.scale is my variable that is initially set to 1. //canvas.mouse is my variable that represents the mouse position relative to the canvas

  • solutions for rapid front-end development?

    - by fayer
    im using mvc framework and i have learned some techniques that help me with different parts of RAD. models: doctrine/visual paradigm controllers/libraries: various design patterns now i only need to know what technique/solution i should use for the views so that i can create views more rapidly. cause i don't think it's efficient to code css/html manually, even though i understand it. its the same principle when using visual paradigm to create both my mysql database tables and doctrine model classes. i believe in using right tools will boost up development speed. so what could i use for the views to save time and energy and don't reinvent the wheel all the time? dreamweaver? any css generation tools? 960/blueprint for layout? suggestions? thanks

  • How can I determine what text on a webpage will render the largest?

    - by TMG
    I'd like to write a function (ideally in PHP) where I can input a url and return a string corresponding to the hypertext from that webpage which would render the largest in a browser (any standard browser is fine). Getting the webpage and tokenizing things with DOM is pretty straightforward, but what's the best way to calculate ultimate size of the rendered text tokens - how do you account for CSS that includes px, em, % etc. for different font sizes. Anyone done something like this before I go and re-invent the wheel? Thanks in advance.

  • Established javascript solution for secure registration & authentication without SSL

    - by Tomas
    Is there any solution for secure user registration and authentication without SSL? With "secure" I mean safe from passive eavesdropping, not from man-in-the-middle (I'm aware that only SSL with signed certificate will reach this degree of security). The registration (password setup, i.e. exchanging of pre-shared keys) must be also secured without SSL (this will be the hardest part I guess). I prefer established and well tested solution. If possible, I don't want to reinvent the wheel and make up my own cryptographic protocols. Thanks in advance.

  • Is there a good open source search engine including indexing bot which can be used to make up speci

    - by Skuta
    Hello, Our application (C#/.NET) needs a lot of queries to search. Google's 50,000 policy per day is not enough. We need something that would crawl Internet websites by specific rules we set (for ex. country domains) and gather URLs, Texts, keywords, name of websites and create our own internal catalogue so we wouldn't be limited to any massive external search engine like Google or Yahoo. Is there any free open source solution we could use to install it on our server? No point in re-inventing the wheel.

  • [C#] Creating standalone, console (shell) for domain-specific operations

    - by mr.b
    Say that I have a system service, and I want to offer a low-level maintenance access to it. For that purpose, I'd like to create a standalone, console application that somehow connects to server process and lets user type in commands, allow it to use auto-completion and auto-suggestion on single/double TAB press (just like linux bash shell, mysql cli, cmd.exe, and countless others), allow command line editing capabilities (history, cursor keys to move around text..), etc. Now, it's not that much of a problem to create something like that by rolling my own from scratch, handling user input, scanning pressed keys, and doing correct actions. But, why reinvent the wheel? Is there some library/framework that helps with this kind of problems, just like readline library that offers improved command-line editing capabilities under linux? Of course, this new "shell" would respond only to valid, domain-specific commands, and would suggest valid arguments, options, switches... Any ideas? Thanks!

  • How to get the next prefix in C++?

    - by Vicente Botet Escriba
    Given a sequence (for example a string "Xa"), I want to get the next prefix in order lexicographic (i.e "Xb"). As I don't want to reinvent the wheel, I'm wondering if there is any function in C++ STL or boost that can help to define this generic function easily? If not, do you think that this function can be useful? Notes The next of "aZ" should be "b". Even if the examples are strings, the function should work for any Sequence. The lexicographic order should be a template parameter of the function.

  • When is it a good idea to use the CSS display property?

    - by allyourcode
    I think I first learned of this property when I thought "I should put this list of items in a ul, but I want it to be laid out horizontally. I wonder if I can do that with CSS?" When I googled this, I found a couple of sites suggesting that I create a CSS rule that would change the value of the display property of the li elements to inline. I've also seen the suggestion that a div (or other block element) be given display: table-cell in order to force the vertical align property to work. These techniques seem kind of hacky. Does that make sense? This might not be a good analogy, but it seems like trying to ride a car as if it were a motorcycle. Yeah, I could replace the steering wheel with handle bars, wear a helmet, and remove all the passenger seating, but how the heck is a car going to drive on two wheels??

  • parsing command option with default values and range constrains in C

    - by agramfort
    Hi, I need to parse command line arguments in C. My arguments are basically int or float with default values and range constrains. I've started to implement something that look like this: option_float(float* out, int argc, char* argv, char* name, description, float default_val, int is_optional, float min_value, float max_value) which I call for example with: float* pct; option_float(pct, argc, argv, "pct", "My super percentage option", 50, 1, FALSE, 0, 100) however I don't want to reinvent the wheel ! My objective is to have error checking of range constrains, throw an error when the option is not optional and is not set. And generate the help message usually given by usage() function. The usage text would look like this: --pct My super percentage option (default : 50). Should be in [0, 100] I've started with getopt but it is too limited for what I want to do and I feel it still requires me to write too much code for a simple usecase like this. thanks

  • Why is UDP + a software reliable ordering system faster than TCP?

    - by Ricket
    Some games today use a network system that transmits messages over UDP, and ensures that the messages are reliable and ordered. For example, RakNet is a popular game network engine. It uses only UDP for its connections, and has a whole system to ensure that packets can be reliable and ordered if you so choose. My basic question is, what's up with that? Isn't TCP the same thing as ordered, reliable UDP? What makes it so much slower that people have to basically reinvent the wheel?

  • How do you calculate expanding mean on time series using pandas?

    - by mlo
    How would you create a column(s) in the below pandas DataFrame where the new columns are the expanding mean/median of 'val' for each 'Mod_ID_x'. Imagine this as if were time series data and 'ID' 1-2 was on Day 1 and 'ID' 3-4 was on Day 2. I have tried every way I could think of but just can't seem to get it right. left4 = pd.DataFrame({'ID': [1,2,3,4],'val': [10000, 25000, 20000, 40000],'Mod_ID': [15, 35, 15, 42], 'car': ['ford','honda', 'ford', 'lexus']}) right4 = pd.DataFrame({'ID': [3,1,2,4],'color': ['red', 'green', 'blue', 'grey'], 'wheel': ['4wheel','4wheel', '2wheel', '2wheel'], 'Mod_ID': [15, 15, 35, 42]}) df1 = pd.merge(left4, right4, on='ID').drop('Mod_ID_y', axis=1)

  • Offline database access

    - by dtech
    I have a small application which basically consists of an user-friendly CRUD interface to a few tables (and joined tables) It currently works with a MySQL database but I would like to make it available offline. My first thought was to create a SQLite "buffer" in between the MySQL database and the application, e.g. by executing all queries on the SQLite but also storing them in a log table so that they can be executed later in the main database with very basic conflict resolution (I will basically let the user solve it if a conflict is detected) Due to the simplicity of the application this shouldn't be too difficult and good exercise, but I think I would be re-inventing the wheel. So my question is: are there existing solutions or other approaches for this problem?

  • Dump Hibernate activity to sql script file

    - by zeven
    Hi, I'm trying to log hibernate activity (only dml operations) to an sql script file. My goal is to have a way to reconstruct the database from a given starting point to the current state by executing the generated script. I can get the sql queries from log4j logs but they have more information than the raw sql queries and i would need to parse them and extract only the helpful statements. So i'm looking for a programatic way, maybe by listening the persist/merge/delete operations and accessing the hibernate-generated sql statements. I don't like to reinvent the wheel so, if anybody know a way for doing this i would appreciate it very much. Thanks in advance

  • Approaches to a week long camp programming course (tips & projects)

    - by Good Person
    I will be teaching a week long programming course to kids between the ages of 11-18. Most of the kids have no programming experience. I'm looking for two things 1) General tips for teaching a camp class (how to make it fun when explaining the difference between int and float) 2) Interesting projects that the kids will be able to complete by the end of the week. Unfortunately the language I'll be required to use is either c++ or Java which means that I'll need to spend more time on itty bitty details than I'd like in a week long course. I feel more competent in c++ than in Java. However if someone can show me that Java is much easier to learn I'll probably teach that instead. My initial idea is to try something like "a game a day" with games like hangman, tic-tac-toe, guess-a-number, wheel-of-fortune, etc. I'll try and update the question text as answers come in to offer more details While there are other questions about teaching programming around I'm looking for advice and tasks that are useful for specifically a week long camp

  • Can an Oracle user get a list of its own running sessions without access to v$session?

    - by Nick Pierpoint
    I have an application that runs a process and I only want one process to run at a time. Some options are: Use an object lock to prevent subsequent processes running. This would be fine, but I want the calling session to return immediately and not wait for the running session to complete. Use a custom Y/N to set whether a process is running or not. I set a "Y" flag at the start of the process and set it to "N" when it finishes or fails. Also fine but feels like I'm re-inventing the wheel and doesn't feel like the way to go. It also falls short if the running session is killed as the flag stays at "Y". Use dbms_application_info.set_module This approach seems the most robust, but if I'm to know there's an existing running process I think I need to be able to query v$session and I don't want this application to have such wide access. Any ideas?

  • Best way to manage the persistence of a form state, to and from a database

    - by Laurent.B
    In a JSP/Servlet webapp, I have to implement a functionality that allows a user to save or restore a form state, that latter containing for instance some search criteria. In other words, the user must be able to save or restore field values of a form, at any time. On the same page that contains that form, there's also another little form that allows him to name his form state before saving it. Then, later he'll be able to recall that state, via a combobox, and refill dynamically the form with the state he selected. I know how to implement that by hand but I would prefer not to reinvent the wheel then I'd like to know if there are some frameworks managing that kind of functionality ? A mix between JSP taglib, filter class, jQuery or other JavaScript frameworks... My research has not give anything yet. Thank you in advance.

  • Why does the Win32-API have so many custom types?

    - by sub
    I'm new to the Win32 API and the many new types begin to confuse me. Some functions take 1-2 ints and 3 UINTS as arguments. Why can't they just use ints? What are UINTS? Then, there are those other types: DWORD LPCWSTR LPBOOL Again, I think the "primitive" C types would be enough - why introduce 100 new types? This one was a pain: WCHAR* I had to iterate through it and push_back every character to an std::string as there wasn't another way to convert it to one. Horrible. Why WCHAR? Why reinvent the wheel? They could have just used char* instead, or?

  • On Writing Blogs

    - by Tony Davis
    Why are so many blogs about IT so difficult to read? Over at SQLServerCentral.com, we do a special subscription-only newsletter called Database Weekly. Every other week, it is my turn to look through all the blogs, news and events that might be of relevance to people working with databases. We provide the title, with the link, and a short abstract of what you can expect to read. It is a popular service with close to a million subscribers. You might think that this is a happy and fascinating task. Sometimes, yes. If a blog comes to the point quickly, and says something both interesting and original, then it has our immediate attention. If it backs up what it says with supporting material, then it is more-or-less home and dry, featured in DBW's list. If it also takes trouble over the formatting and presentation, maybe with an illustration or two and any code well-formatted, then we are agog with joy and it is marked as a must-visit destination in our blog roll. More often, however, a task that should be fun becomes a routine chore, and the effort of trawling so many badly-written blogs is enough to make any conscientious Health & Safety officer whistle through their teeth at the risk to the editor's spiritual and psychological well-being. And yet, frustratingly, most blogs could be improved very easily. There is, I believe, a simple formula for a successful blog. First, choose a single topic that is reasonably fresh and interesting. Second, get to the point quickly; explain in the first paragraph exactly what the blog is about, and then stay on topic. In writing the first paragraph, you must picture yourself as a pilot, hearing the smooth roar of the engines as your plane gracefully takes air. Too often, however, the accompanying sound is that of the engine stuttering before the plane veers off the runway into a field, and a wheel falls off. The author meanders around the topic without getting to the point, and takes frequent off-radar diversions to talk about themselves, or the weather, or which friends have recently tagged them. This might work if you're J.D Salinger, or James Joyce, but it doesn't help a technical blog. Sometimes, the writing is so convoluted that we are entirely defeated in our quest to shoehorn its meaning into a simple summary sentence. Finally, write simply, in plain English, and in a conversational way such that you can read it out loud, and sound natural. That's it! If you could also avoid any references to The Matrix then this is a bonus but is purely personal preference. Cheers, Tony.

  • Text Trimming in Silverlight 4

    - by dwahlin
    Silverlight 4 has a lot of great features that can be used to build consumer and Line of Business (LOB) applications. Although Webcam support, RichTextBox, MEF, WebBrowser and other new features are pretty exciting, I’m actually enjoying some of the more simple features that have been added such as text trimming, built-in wheel scrolling with ScrollViewer and data binding enhancements such as StringFormat. In this post I’ll give a quick introduction to a simple yet productive feature called text trimming and show how it eliminates a lot of code compared to Silverlight 3. The TextBlock control contains a new property in Silverlight 4 called TextTrimming that can be used to add an ellipsis (…) to text that doesn’t fit into a specific area on the user interface. Before the TextTrimming property was available I used a value converter to trim text which meant passing in a specific number of characters that I wanted to show by using a parameter: public class StringTruncateConverter : IValueConverter { #region IValueConverter Members public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { int maxLength; if (int.TryParse(parameter.ToString(), out maxLength)) { string val = (value == null) ? null : value.ToString(); if (val != null && val.Length > maxLength) { return val.Substring(0, maxLength) + ".."; } } return value; } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new NotImplementedException(); } #endregion } To use the StringTruncateConverter I'd define the standard xmlns prefix that referenced the namespace and assembly, add the class into the application’s Resources section and then use the class while data binding as shown next: <TextBlock Grid.Column="1" Grid.Row="3" ToolTipService.ToolTip="{Binding ReportSummary.ProjectManagers}" Text="{Binding ReportSummary.ProjectManagers, Converter={StaticResource StringTruncateConverter},ConverterParameter=16}" Style="{StaticResource SummaryValueStyle}" /> With Silverlight 4 I can define the TextTrimming property directly in XAML or use the new Property window in Visual Studio 2010 to set it to a value of WordEllipsis (the default value is None): <TextBlock Grid.Column="1" Grid.Row="4" ToolTipService.ToolTip="{Binding ReportSummary.ProjectCoordinators}" Text="{Binding ReportSummary.ProjectCoordinators}" TextTrimming="WordEllipsis" Style="{StaticResource SummaryValueStyle}"/> The end result is a nice trimming of the text that doesn’t fit into the target area as shown with the Coordinator and Foremen sections below. My data binding statements are now much smaller and I can eliminate the StringTruncateConverter class completely.   For more information about onsite, online and video training, mentoring and consulting solutions for .NET, SharePoint or Silverlight please visit http://www.thewahlingroup.com.
