  • How to check if datetime is older than 20 seconds.

    - by Jelle
    Hello! This is my first time here so I hope I post this question at the right place. :) I need to build flood control for my script but I'm not good at all this datetime to time conversions with UTC and stuff. I hope you can help me out. I'm using the Google App Engine with Python. I've got a datetimeproperty at the DataStore database which should be checked if it's older than 20 seconds, then proceed. Could anybody help me out? So in semi-psuedo: q = db.GqlQuery("SELECT * FROM Kudo WHERE fromuser = :1", user) lastplus = q.get() if lastplus.date is older than 20 seconds: print"Go!"

  • Are Inherited Forms And/Or Inherited Controls possible in Managed C++

    - by Ali Akdurak
    Hello everyone The question is actually pretty self explanatory but I will further clarify it. I am building a simple application to show a load [file] for 5 different types of [files]. So all these 5 forms will have similar GUI elements such as a listbox and a load button with a small textbox/label to show the summary of the [file]'s information. My desired effect is something like visual studio's C# template for Inherited User controls or Inherited forms. I already heavily googled the concept to look for a C++ visual studio template to the trick but I couldn't find it. The word [file] is in brackets because open file dialogue will not the trick as this list of files to select form comes form an SQL server. Thanks a lot!

  • Inverted index in a search engine

    - by Ayman
    Hello there, I'm trying to write some code to make a small application for searching text from files. Files should be crawled, and I need to put an inverted index to boost searches. My problem is that I kind of have ideas about how the parser would be, I'm willing to implement the AND, NOT, OR in the query. Whereas, I couldn't figure out how my index should be... I have never created an inverted index so if any body could suggest a feasable way to do it I would be very grateful... I do know in theory how it works but my problem is I absolutely have no idea to make happen in MySql I need to give keywords being indexed a weight too... Thank you so much.

  • How to determine Windows.Diagnostics.Process from ServiceController

    - by Alex
    This is my first post, so let me start by saying HELLO! I am writing a windows service to monitor the running state of a number of other windows services on the same server. I'd like to extend the application to also print some of the memory statistics of the services, but I'm having trouble working out how to map from a particular ServiceController object to its associated Diagnostics.Process object, which I think I need to determine the memory state. I found out how to map from a ServiceController to the original image name, but a number of the services I am monitoring are started from the same image, so this won't be enough to determine the Process. Does anyone know how to get a Process object from a given ServiceController? Perhaps by determining the PID of a service? Or else does anyone have another workaround for this problem? Many thanks, Alex

  • Strange Exception on getGeneratedKeys() with JDBC for MySQL 5.1

    - by sweeney
    Hello, I'm using JDBC to insert a row into a MYSQL database. I build a parameterized command, execute it and attempt to retrieve the auto generated keys as follows: String sql = "INSERT IGNORE INTO `users` (`email`, `pass-hash`) VALUES (?, ?)"; Connection conn = SQLAccess.getConnection(); PreparedStatement ps = conn.prepareStatement(sql); ps.setString(1, login); ps.setString(2, passHash); int count = ps.executeUpdate(); if (count == 1) { ResultSet rs = ps.getGeneratedKeys(); rs.next(); //some more stuff... } For some reason, I get the following SQLException on the line containing ResultSet rs = ps.getGeneratedKeys();: !Statement.Generated Keys Not Requested! Any thoughts? When I run the same query, as generated by running the app through the debugger, in a MySQL browser it executes without incident. Thanks, brian

  • Saving a huge dataset into SQL table in a XML column - MS SQL, C#.Net

    - by NLV
    Hello all I'm having a requirement where i've to save a dataset which has multiple tables in it in a sql table XML column by converting into an XML. The problem is that in some cases the dataset grows extremely huge and i get OutOfMemoryException. What i basically do is that i convert the dataset into an xml file and save it in the local disk and then load the XML again and send it as a stored procedure parameter. But when i write the dataset xml into the disk the file sizes over 700 Mb and when i load it in the XMLDocument object in memory i get OutOfMemoryException. How can get the dataset xml without saving it in a file and re-reading it again? Thank You NLV

  • Web Crawling Sites with Javascripts or web forms

    - by Jojo
    Hello everyone, I have a webcrawler application. It successfully crawled most common and simple sites. Now i ran into some types of websites wherein HTML documents are dynamically generated through FORMS or javascripts. I believe they can be crawled and I just don't know how. Now, these websites do not show the actual HTML page. I mean if I browse that page in IE or firefox, the HTML code does not match what's actually in the IE or firefox. These sites contain textboxes, checkboxes, etc... so I believe they are what they call "Web Forms". Actually I am not much familiar with web development so correct me if I'm wrong. My question is, does anyone in similar situation as I am now and have successfully solved these types of "challenges"? Does anyone know of a certain book or article regarding web crawling? Those that pertains to these advanced type of websites? Thanks.

  • Objective-C : Member variable is losing reference between method calls.

    - by Winston
    Hello, I've been having with an objective-c class which appears to be losing its pointer reference between methods of the same class. In the MyTableViewController.h file, I declare: @interface SettingsTableViewController : UITableViewController <UITextFieldDelegate>{ OCRAppDelegate *delegate; } MyTableViewController.m file - (id) init { self = [ super initWithStyle: UITableViewStyleGrouped ]; delegate = [(OCRAppDelegate *)[[UIApplication sharedApplication] delegate] retain]; } The problem is when the "MyTableViewController" view appears again and a different method is executed within that same class, the delegate pointer (which was assigned during the init method) is no longer there. I tried to retain, but to no avail. Would anyone know why this is, it seems like perhaps it is a fundamental Objective-C issue which I am missing. Appreciate your help. Thanks, Winston

  • WPF: Create a dialog / prompt

    - by stefan.at.wpf
    Hello, I need to create a Dialog / Prompt including TextBox for user input. My problem is, how to get the text after having confirmed the dialog? Usually I would make a class for this which would save the text in a property. However I want do design the Dialog using XAML. So I would somehow have to extent the XAML Code to save the content of the TextBox in a property - but I guess that's not possible with pure XAML. What would be the best way to realize what I'd like to do? How to build a dialog which can be defined from XAML but can still somehow return the input? Thanks for any hint!

  • Jquery - effect + autohide

    - by lidermin
    Hello, I'm using jquery to animate a bit my web site, but I'm having a little issue with some behaviour: I have a div, which suddenly appears from the top of the page and shakes: $(minipopup).animate({ marginTop: '+=' + (240) + 'px' }, 1000); $(minipopup).effect("shake"); This mini popup has an X for closing it, or else, it will auto close after a few seconds: setTimeout(function() { $('#minipopup').effect("explode"); }, 10000); $('#closePopup').click(function() { $('#minipopup').effect("explode"); }); Everything works, except that, if the user clicks the CLOSE button, he sees the explode effect and the popup effectively dissapears, but after the 10 seconds pass (the one I defined under the setTimeout), the user again sees the popup explosion (just the effect, cause the popup is not there visually). How could I avoid that "ghost" explosion if the user already closed the popup manually? Thanks in advance.

  • How do programmers work together on a project?

    - by Laith J
    Hello, I've always programmed alone, I'm still a student so I never programmed with anyone else, I haven't even used a version control system before. I'm working on a project now that requires knowledge of how programmers work together on a piece of software in a company. How is the software compiled? Is it from the version control system? Is it by individual programmers? Is it periodic? Is it when someone decides to build or something? Are there any tests that are done to make sure it "works"? Anything will do. Thanks.

  • how to implement color search with sphinx?

    - by harald
    hello, searching a photo by dominant colors using mysql is quite simple. assuming that the r,g,b values of the most dominant colors of the photo is already stored in the database, this could be achieved for example by something like: SELECT * FROM colors WHERE ABS(dominant_r - :r) < :threshold AND ABS(dominant_g - :g) < :threshold AND ABS(dominant_b - :b) < :threshold i wonder, if it's anyhow possible to store the colors in sphinx and perform the querying using the sphinx search engine? thanks!

  • Wrong assembly-references for Silverlight Sketchflow project in Blend 3

    - by persistent
    Hello, In my installation of Blend 3, the SketchStyles are missing when a new project is created. I found out that this is because the following automatic references in the project are wrong: Microsoft.Expression.Interactions Microsoft.Expression.Prototyping.Interactivity Microsoft.Expression.Prototyping.RunTime Microsoft.Expression.Prototyping.SketchControls In the project references these all point to my project path (where they don't live). If I remove them manually, and instead set the references to ie this: "c:\Program Files (x86)\Microsoft SDKs\Expression\Blend 3\Interactivity\Libraries\Silverlight\Microsoft.Expression.Interactions.dll" everything works. Any ideas on why, and how to fix this? Could it be the project template somehow? TIA

  • How to organize a ASP.NET MVC solution (DDD)

    - by vandalo
    Hello everyone. I am trying to start a new project (asp.net MVC) and I would like to apply some DDD rules I've learned in these last few months. I don't know how to organize my solution though. I would like to use Nhibernate but I don't want to use Fluent Nhibernate cause it must be something like an experiment. I've seen some examples where people keep everything in the same project. Some others tend to create a different project for everything. Do you think I should differentiate the model and the repository or put it in the same project? If someone has some links to articles etc it would be appreciated. thanks Alberto

  • What (kind of) project could I create to learn JavaScript?

    - by Aziz Light
    Hello, I started learning JavaScript a while ago. It's a fairly easy programming language considering that I learned Java in university, that I know php pretty well and that I already played around with python and ruby. The problem is that to properly learn a programming language I usually create a project. In javascript, I just don't know what kind of project I could create - that is, a project that is not web-based or related to the web browser. Can I create javascript shell scripts? Where is javascript commonly used beside the web browsers? So, can someone actually give me some ideas please?

  • How the return type is determined in a method that uses Linq2Sql?

    - by Richard77
    Hello, I've usually have difficulties with return types when it comes to linq. I'll explain by the following examples. Let's say I have a Table Products with ProductID, Name, Category, and Price as columns : 1) IQueryable<Product public IQueryable<Product> GetChildrenProducts() { return (from pd in db.Products where pd.Category == "Children" select pd); } 2) Product public Product GetProduct(int id) { return (from pd in db.Products where pd.ProductID == id select pd).FirstOrDefault(); } Now, if I decide to select, for instance, only one column (Price or Name) or even 2 or 3 columns (Name and Price), but in any case, less than the 4 columns, what's going to be the return type? I mean this: public returnType GetSomeInformation() { return (from pd in db.Products select new { pd.Name, pd.Price } } What SHOULD BE the returnType for the GetSomeInformation()? Thanks for helping

  • MySQL Need help constructing query: join multiple tables into single row

    - by Jed Daniels
    Hello stackoverflowers, Forgive me if this question has been asked and answered, I've searched and found a few that look similar but I'm too much of a novice with SQL to adapt them to my needs. Also forgive me if I don't use the correct terminology, I know it can be annoying when someone asks a question and they don't even know enough to be able to ask for what they need. I'm helping a friend gather some data, and need to perform a query that results in a single row per record, but instead I get multiple rows. Here is an example of what I'm querying right now (simplified, hopefully not too much): SELECT * FROM `table_one` AS t1 INNER JOIN `table_two` AS t2 ON t1.id = t2.id INNER JOIN `table_three` AS t3 ON t1.id = t3.id WHERE 1 The result is: id text number 5 Subtotal 17 5 Tax 3 5 Total 20 What I need is to create a query that results in something more like this: id text number text number text number 5 subtotal 17 Tax 3 Total 20 Any assistance/guidance would be much appreciated. Thanks! --jed

Any one knows how to do that? 10x :-)
