  • Ideas for Quick Hierarchical Listing - .NET

    - by Robert
    I have a table in SQL Server listing corporate departments and their sections and subsections (3 levels). I would like to create some web-based listing of this, but similar to a TreeList. I was thinking to set up nested Ajax Accordions, but it was taking me way too long to put together. I would even settle for a GridView with non-repeating column values. Is there a way I can implement my idea without it taking me more than an hour or so for a newbie to complete? Any controls in ASP.NET or Ajax I can bind to would be great.

  • String Encoding doesn't ouput all characters

    - by AndroidXTr3meN
    My client uses InputStreamReader/BufferedReader to fetch text from the Internet. However when I save the Text to a *.txt the text shows extra weird special symbols like 'Â'. I've tried Convert the String to ASCII but that mess upp å,ä,ö,Ø which I use. I've tried food = food.replace("Â", ""); and IndexOf(); But string won't find it. But it's there in HEX Editor. So summary: When I use text.setText(Android), the output looks fine with NO weird symbols, but when I save the text to *.txt I get about 4 of 'Â'. I do not want ASCII because I use other Non-ASCII character. The 'Â' is displayed as a Whitespace on my Android and in notepad. Thanks! Have A great Weekend! EDIT* found:   in Wordpad

  • Disable Primary Key and Re-Enable After SQL Bulk Insert

    - by Jon
    I am about to run a massive data insert into my DB. I have managed to work out how to enable and rebuild non-clustered indexes on my tables but I also want to disable/enable primary keys. You can't disable the clustered index for the primary key as the table is inaccessible when that is done and my attempt to do a ALTER TABLE for constraints does not work as I think that is only for foreign keys. Do you know of a way to Disable the Primary Key and Re-Enable After SQL Bulk Insert. NOTE: This is over numerous tables and so I don't know the exact primary key specifications eg/name etc

  • Can a regex return a match that's not a part of the original string?

    - by Vishnu
    I'm using an application that requires me to provide a regex for various files. It uses the matches from the regex to uniquely identify each file and then use a data store to retrieve metadata about these files. there is however a problem with the application, so it assumes that the data which is used to identify each file is only numeric data. Hence, it stores the results of matches in integers. I control the data store but not the names of the files. Since the application has a bug in it, I was hoping that I could use an encoding scheme to convert the non-numeric data to an integer. But for that I'd require the regex to return something that's not part of the original string as a match. Is this possible?

  • Maven workspace resolution horked

    - by user237815
    I'm using m2eclipse to manage maven projects. Somehow I did a bad thing, and now the system is behaving as if workspace resolution is disabled. I have several projects that depend on a main project. This project has a version of 4.0-SNAPSHOT, and all the dependent projects reference it in the dependencies section of their poms. Everything was working fine until I created an entirely new project and mistakenly copied the pom from the main project into the new project. Suddenly, all of the dependent projects got the error: "The container 'Maven Dependencies" references non existing library C:\users\myusername.m2\com\mydomain\myproject\4.0-SNAPSHOT\myproject-4.0-SNAPSHOT.jar I zapped the offending new project, but the error remains for all the dependent projects. I've made no changes (to my knowledge) in the main project or any of the dependent projects, so I'm guessing something got changed in the Eclipse environment. Does m2eclipse or Maven itself maintain settings anywhere that I can blow away?

  • What open source document-oriented database system is most mature for Windows usage?

    - by jdk
    After using relational databases as back-end storage all my Windows programming life (currently .NET), I want to experiment with a document-oriented database by this Wikipedia definition; it can be standalone or layered over an existing non-commercial database system. What open source document-oriented database solution would you recommend from your own experience and why? A nice to have would be a .NET provider. Admittedly this is somewhat subjective and potentially argumentative so keep it real folks and I'll do the same - also your answers will be invaluable to others looking into document-oriented databases for the first time on Windows. I'm sure the overall value of your answers will outweigh any biases. Thanks.

  • Check if a MediaWiki page exists (Python)

    - by compie
    I'm working on a Python script that transforms this: foo bar Into this: [[Component foo]] [[bar]] The script checks (per input line) if the page "Component foo" exists. If it exists then a link to that page is created, if it doesn't exist then a direct link is created. The problem is that I need a quick & cheap way to check if a lot of wiki pages exist.I don't want to (try to) download all the 'Component' pages. I already figured out a fast way to do this by hand: Edit a new wiki page. paste all the 'component' links into the page, press preview, and then save the resulting preview HTML page. The resulting HTML file contains a different link for existing pages than for non-existing pages. So to rephrase my question: How can I save a mediawiki preview page in Python?

  • Move/copy files/folder in linux/solaris using only bash built-ins

    - by KullDox
    There was a situation when somebody moved the whole rootdir into a subdir on a remote system, thus all the system tools like cp, mv, etc didn't work anymore. We had an active session though but couldn't find a way to copy/move the files back using only bash built-ins. Do somebody know of a way to achieve this? I even thought about copy the cp or mv binary in the currentdir with while read -r; do echo $LINE; done and then redirect this to a file, but it didn't work. Guess because of all the special non printable chars in a binary file that can't be copied/displayed using echo. thanks.

  • Alternatives libraries for loading PNG images

    - by Robert
    My java J2SE application is reading a lot of (png) images from the web and some of them use features such as a transparency color for true-color images (tRNS section) that Sun's/Oracle's PNGImageReader implementation simply ignores. Therefore the common solution for loading via ImageIO.read(...); does not work for me as it relies on this incomplete PNGImageReader implementation. Does anybody know a png reader implementation that can read all forms of PNG images correctly - those with color table or true-color and alpha transparency or transparent color? As it is for a GPL project it should be a non-commercial one that can be included without licensing problems into the app. Edit: My be this question was too specific. Therefore let be redesign my question: Who knows alternative implementations and libraries that are able to load PNG files? I will then test the implementations for their capabilities to load some test png images. Edit2: The end result have to be a BufferedImage

  • Sql Server performance

    - by Jose
    I know that I can't get a specific answer to my question, but I would like to know if I can find the tools to get to my answer. Ok we have a Sql Server 2008 database that for the last 4 days has had moments where for 5-20 minutes becomes unresponsive for specific queries. e.g. The following queries run in different query windows simultaneously have the following results SELECT * FROM Assignment --hangs indefinitely SELECT * FROM Invoice -- works fine Many of the tables have non-clustered indexes to help speed up SELECTs Here's what I know: 1) The same query will either hang indefinitely or run normally. 2) In Activity Monitor in the processes tab there are normally around 80-100 processes running I think that what's happening is 1) A user updates a table 2) This causes one or more indexes to get updated 3) Another user issues a select while the index is updating Is there a way I can figure out why at a specific moment in time SQL Server is being unresponsive for a specific query?

  • Can functions like sin() be redefined, in Fortran, C or Java?

    - by EOL
    Can a mathematical function like sin() be redefined, in Fortran, C or Java code, while preserving the default behavior of other mathematical functions like cos()? Or can another function named sin() but that accepts different argument types be defined in addition to the built-in sin()? I am interested in general features of these languages (I am thinking of applications like the implementation of non-usual number algebras). I tried to define a sin() function in a Fortran 95 program, but the intrinsic sin() function was called instead… Is there a way around this? what about C and Java?

  • Multiple Rails forks with separate designs and layouts

    - by mettadore
    I have a Rails project that is basically a simple web app for a membership-based organization. We've open sourced the code on Github for the web app so that others can use it, but have a licensed design/layout that the original organization is going to use. This layout cannot be open sourced. I was wondering if others have run into the situation where you have an open-source Rails app with a non-OS design. My initial thought is to put app/views in .gitignore, and to have anyone forking the code add their own views directory, perhaps including an app/views_default directory with a web-app-theme layout or something else to get people running. Is this the best option (realizing that there are other files such as JavaScript, CSS, etc that come with the layout that must also be ignored). Does anyone have some good thoughts or pointers on this?

  • d3 tree - parents having same children

    - by Larry Anderson
    I've been transitioning my code from JIT to D3, and working with the tree layout. I've replicated http://mbostock.github.com/d3/talk/20111018/tree.html with my tree data, but I wanted to do a little more. In my case I will need to create child nodes that merge back to form a parent at a lower level, which I realize is more of a directed graph structure, but would like the tree to accomodate (i.e. notice that common id's between child nodes should merge). So basically a tree that divides like normal on the way from parents to children, but then also has the ability to bring those children nodes together to be parents (sort of an incestual relationship or something :)). Asks something similar - How to layout a non-tree hierarchy with D3 It sounds like I might be able to use hierarchical edge bundling in conjunction with the tree hierarchy layout, but I haven't seen that done. I might be a little off with that though.

  • How to structure web application with part of it being secured (SSL)

    - by spirytus
    What is the common pattern to structure web application where part of it has to be secured. So lets say I have page_a and page_b which do not need to be secured, although should display login information (login fields or login details once user logged in). This web app. also would have secured pages (admin, checkout or similar) secure_page_c and secure_page_d. My questions are: What is the common folder structure for such assuming I code in php with no frameworks? Also how shall I deal with session variables in case user navigates lets say from secure_page_b to non secure page_a or vice versa? What else might be a problem and should be considered when coding that kind of app in php? Thank you all for any suggestions

  • MySQL order by error in PHP

    - by theflyinghaiwian
    Hi, I'm making a simple cms system for a site I'm making for non-tech users to edit... So far so good but when I try and run this code I keep getting: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''pages' ORDER BY 'pages'.'pageOrder' ASC LIMIT 0 , 30' at line 1 By the error it looks like a problem with the order by section and indeed it works without it... $sql = "SELECT * FROM 'pages' ORDER BY 'pages'.'pageOrder' ASC LIMIT 0 , 30"; $result = mysql_query($sql) or die(mysql_error()); Now I know there is nothing wrong with the code because originally I wrote my own SQL but then after it failed I robbed some from phpmyadmin and it still gives the error but it works in phpmyadmin... I'm really at my wits end with this, help is very much appreciated thank you...

  • Seeking not working in HTML5 audio tag

    - by lord_wilmore
    I have a lighttpd server running locally. If I load a static file on the server (through an html5 audio tag), it plays and seeks fine. However, seeking doesn't work when running a dev server (web.py/CherryPy) or if I return the bytes via a defined action url instead of as a static file. It won't load the duration either. According to the "HTTP byte range requests" section in this Opera Page it's something to do with support for byte range requests/partial content responses. The content is treated as streaming instead. What I don't understand is: If the browser has the whole file downloaded surely it can display the duration, and surely it can seek. What I need to do on the web server to enable byte range requests (for non-static urls). Any advice would be most gratefully received.

  • Looking for a clear and concise web page explaining why lower bits of random numbers are usually not

    - by Hamish Grubijan
    I am putting together an internal "every developer should know" wiki page. I saw many discussions regarding rand() % N, but not a single web page that explains it all. For instance, I am curious if this problem is only C- and Linux-specific, or if it also applies to Windows, C++,. Java, .Net, Python, Perl. Please help me get to the bottom of this. Also, just how non-random do the numbers get? Thank you!

  • Ideal timeout period for dns lookup

    - by railscoder
    In my rails app i do a nslookup using a ruby library resolv. If the site like dgdfgdfgdfg.com is entered its talking too long to resolve. in some instance like 20 sec.(mostly for non-existent sites) Because it cause the application to slowdown. So i though of introducing a timeout period for the dns lookup. What will be the ideal timeout period for the dns lookup so that resolution of actual site doesnt fail. will something like 10 sec will be fine?

  • Why does s ++ t not lead to a stack overflow for large s?

    - by martingw
    I'm wondering why Prelude> head $ reverse $ [1..10000000] ++ [99] 99 does not lead to a stack overflow error. The ++ in the prelude seems straight forward and non-tail-recursive: (++) :: [a] -> [a] -> [a] (++) [] ys = ys (++) (x:xs) ys = x : xs ++ ys So just with this, it should run into a stack overflow, right? So I figure it probably has something to do with the ghc magic that follows the definition of ++: {-# RULES "++" [~1] forall xs ys. xs ++ ys = augment (\c n -> foldr c n xs) ys #-} Is that what helps avoiding the stack overflow? Could someone provide some hint for what's going on in this piece of code?

  • DependencyProperty Orientation problem

    - by byte
    I am learning WPF and am trying to create my first UserControl. My UserControl consists of StackPanel StackPanel contains a Label and TextBox I am trying to create two Dependency Properties Text for the Label Orientation for the StackPanel - The orientation will affect the position of the Label and TextBox effectively I have successfully created a Text dependency property and bind it to my UserControls .

  • Writable folder by all users on the same pc

    - by Catalin DICU
    I have a desktop .NET WPF application witch uses an embedded database (SQLite). Where to put the database file ? It's the same database for all users. I tried to use CommonAppData but it's not writable by non-admin users. So I tried to use a custom installer action to give write rights to all users to this folder but it fails on domain PCs. The code is: DirectorySecurity security = Directory.GetAccessControl(appDataPath); FileSystemAccessRule rule = new FileSystemAccessRule("Users", FileSystemRights.WriteData, InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit, PropagationFlags.InheritOnly, AccessControlType.Allow); security.AddAccessRule(rule); Directory.SetAccessControl(appDataPath, security); Would ".\Users" insead of "Users" work on a domain ? Is this the best approach ? Is there any other folder I could use ?

  • iPhone OpenGL Template is cheating?

    - by carrots
    XCode's OpenGL template seems to be cheating to solve this "stretched" viewport problem I've been trying to understand for the last 3 hours. In the iphone "OpenGL ES Application" template, the colorful square that bounces up and down on the screen is not really a square at all! ES1Renderer.m (the ES2 file as well) static const GLfloat squareVertices[] = { -0.5f, -0.33f, 0.5f, -0.33f, -0.5f, 0.33f, 0.5f, 0.33f, }; But it comes out looking square on the device/simulator due to the stretching/squashing effect of a non-square viewport. I tried to fix it by fiddling with glFrustumf() but that doesn't seem to change the aspect ratio. I was able to get things looking good (not-stretched) when I fed glViewport() with a 1:1 widht:height.. But this doesn't seem like the answer because it offsets the viewport placement. What's the right way to correct for this stretching and why doesn't XCode do it that way?

  • Anonymous users support vs Google bot

    - by Andy
    I have a User class in my web app that represents a user currently logged in. Every time a user vists a page, a User instance is populated based on authentication data supplied in cookies. A User instance is created even if an anonymous user logs in - and a corresponding new record is created in the User table in the database. This approach allows me to save some state info for the current user regardless of its type. The problem however with this approach is the Google bot, and other non-human web organisms crawling my pages. Every time a bot starts to walk around the site, thousands of useless records will be created in the database, each of them only to be used for a single page. Question: what is the best trade off? How to support anonymous users, save their state, and don't get too much overhead because of cookieless bots?

  • Differing form size between XP and 7

    - by Andy
    I am developing a C# WinForms app on my XP dev machine with Visual C# Express 2008. I set the form to have a size of my liking with Width and Height on the designer and all looks good. I also set these dimensions to the MaximumSize property. Deploying the app to another XP machine, and the app looks like it does on my dev. However, in testing the app on a Win7 machine, the form has both horizontal and vertical scrollbars applied. I assume that this is due to the changed non-client size of the form, as determined by Win7. I can resize the window, but I would like it to be displayed correctly to begin with. So, my question is: What is the best way to correctly maintain a form size client area across OS'es? Thanks all.
