  • ASP.NET content incode id

    - by WtFudgE
    Hi, I recently started using Masterpages, the thing is I would like to add text in code to an asp:Content tag. So my content page markup code is: <%@ Page Language="C#" MasterPageFile="~/Template.Master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="ASP_Test_WebApp.Default" %> <asp:Content id="TEST" ContentPlaceHolderID="Main" Runat="Server" /> So now I would like to add Contents to the "TEST" id incode. But my in code doesn't recognize TEST. If I don't use a masterpage and I give an id to a tag my in code reconigzes it, but now that I started using masterpages it doesn't. What am I doing wrong? Thx

  • Best Fit Scheduling Algorithm

    - by Teegijee
    I'm writing a scheduling program with a difficult programming problem. There are several events, each with multiple meeting times. I need to find an arrangement of meeting times such that each schedule contains any given event exactly once, using one of each event's multiple meeting times. Obviously I could use brute force, but that's rarely the best solution. I'm guessing this is a relatively basic computer science problem, which I'll learn about once I am able to start taking computer science classes. In the meantime, I'd prefer any links where I could read up on this, or even just a name I could Google.

  • How do I automate navigation to a website that requires authentication?

    - by Wiz
    Here's what I'm trying to achieve. I would like to write a script that will navigate to a website that requires me to be authenticated as myself, say Facebook, Live Spaces, Twitter or any other, and then have that script search for certain information on one of the pages of the website. I've done something similar in the past with the Windows.Forms WebBrowser control, which is a full blown implementation of IE that can be controlled through code and will store whatever cookies you get once you're authenticated, but it was very unfriendly to modify and I was hoping to use a scripting language instead, maybe Powershell or something of that sort. Are there maybe some good tutorials about this out there on the web? Thanks!

  • Gantt Chart online

    - by Luca
    I need to insert a horizontal bar chart in a web page. The thing I have to do is very similar to a Gantt Chart. I'd like to use a javascript library for the purpose. I tried jsgantt, but actually it is not very beautiful. I could evaluate also a server generation of the graph. In case my server side language is Python. It will be part of an internal project with no internet access, so Google Charts isn't an option.

  • Android Emulator - Cannot get keyboard to display

    - by Ash
    Basically I cannot get the onscreen keyboard to display at all. I've tried every solution I've read to make it appear within my application, and now I've come to the conclusion that it must be the emulator as it isn't appearing when using Messages, writing e-mails etc. I've looked in Language & input within settings and checked Sample Soft Keyboard, rebooted the emulator with no change. Using Android SKD 2.3.3 3.7in WVGA (Nexus One) I'm hoping someone can maybe guess what's going on. Many thanks

  • Best practices for combining Lucene.NET and a relational database?

    - by FlySwat
    I'm working on a project where I will have a LOT of data, and it will be searchable by several forms that are very efficiently expressed as SQL Queries, but it also needs to be searched via natural language processing. My plan is to build an index using Lucene for this form of search. My question is that if I do this, and perform a search, Lucene will then return the ID's of matching documents in the index, I then have to lookup these entities from the relational database. This could be done in two ways (That I can think of so far): N amount of queries (Horrible) Pass all the ID's to a stored procedure at once (Perhaps as a comma delimited parameter). This has the downside of being limited to the max parameter size, and the slow performance of a UDF to split the string into a temporary table. I'm almost tempted to mirror everything into lucenes index, so that I can periodicly generate the index from the backing store, but only need to access it for the frontend. Advice?

  • Singleton again, but with multi-thread and Objective-C

    - by Tonny Xu
    I know Singleton pattern has been discussed so much. But because I'm not fully understand the memory management mechanism in Objective-C, so when I combined Singleton implementation with multithreading, I got a big error and cost me a whole day to resolve it. I had a singleton object, let's call it ObjectX. I declared an object inside ObjectX that will detach a new thread, let's call that object objectWillSpawnNewThread, when I called [[ObjectX sharedInstance].objectWillSpawnNewThread startNewThread]; The new thread could not be executed correctly, and finally I found out that I should not declare the object objectWillSpawnNewThread inside the singleton class. Here are my questions: How does Objective-C allocate static object in the memory? Where does Objective-C allocate them(Main thread stack or somewhere else)? Why would it be failed if we spawn a new thread inside the singleton object? I had searched the Objective-C language [ObjC.pdf] and Objective-C memory management document, maybe I missed something, but I currently I could not find any helpful information.

  • Where do I find a good explanation of Javascript-ese

    - by tzenes
    I realize that title may require explanation. The language I first learned was C, and it shows in all my programs... even those not written in C. For example, when I first learned F# I wrote my F# programs like C programs. It wasn't until someone explained the pipe operator and mapping with anonymous functions that I started to understand the F#-ese, how to write F# like a F# programmer and not a C programmer. Now I've written a little javascript, mostly basic stuff using jquery, but I was hoping there was a good resource where I could learn to write javascript programs like a javascript programmer.

  • Objective-c string appending causes exception

    - by Dave C
    Hello Everyone, The following code is causing me some problems. The third line causes a program crash... it doesn't happen the first time I step through but somehow later on in the program. If I comment out that third line, the program runs smoothly. NSString *myRequestString = @"text"; int i = 1; myRequestString = [myRequestString stringByAppendingString:[NSString stringWithFormat: @"t=%d", i]]; That code causes this exception: * -[CFString release]: message sent to deallocated instance 0xb4c43fe0 On a side note, can anyone tell me how to concatenate strings in objective-c like any other normal language... I can't believe that there is no concatenation operator. Any and all help is greatly appreciated.

  • What is C's analogy to LabVIEW's Event Structure?

    - by SiegeX
    One programming construct I use quite a bit in LabVIEW is the Event Structure. This gives me the benefit of not having to needlessly waste CPU cycles via polling but only perform actions when an event I'm interested in is generated. As an experienced LabVIEW programmer with a decent understanding of C, I'm curious how one would go about emulating LabVIEW's event structure in C; preferably under Linux. A small code sample (like the one in the link above) illustrating how this might be done would be much appreciated. Also, if there already exists 3rd party libraries (for Linux) to add this event framework to C, that would be nice to know as well. Thanks.

  • Web framework for an application utilizing existing database?

    - by tputkonen
    A legacy web application written using PHP and utilizing MySql database needs to be rewritten completely. However, the existing database structure must not be changed at all. I'm looking for suggestions on which framework would be most suitable for this task? Language candidates are Python, PHP, Ruby and Java. According to many sources it might be challenging to utilize rails effectively with existing database. Also I have not found a way to automatically generate models out of the database. With Django it's very easy to generate models automatically. However I'd appreciate first hand experience on its suitability to work with legacy DBs. Also I appreciate suggestions of other frameworks worth considering.

  • AHCI Driver for own OS

    - by user1496761
    I have been programming a little AHCI driver for two weeks. I have read this article and Intel's Serial ATA Advanced Host Controller Interface (AHCI) 1.3. There is an example, which shows how to read sectors via DMA mode (osdev.org). I have done this operation (ATA_CMD_READ_DMA 0xC8) successfully, but when i tried to write sectors (ATA_CMD_WRITE_DMA 0xCA) to the device, the HBA set the error Offset 30h: PxSERR – Port x Serial ATA Error - Handshake Error (this is decoding from Intel AHCI specification). I don't understand why it happened. Please, help me. In addition, I have tried to issue the command IDENTIFY 0xEC, but not successfully...

  • Adding text over existing PDFs using reportlab

    - by Shane
    I'm interested in filling out existing PDF forms programatically. All I really need to do is pull information from user input and then place the appropriate text over an existing PDF in the appropriate locations. I can already do this with reportlab by feeding the same sheet of paper into a printer, twice, but this just really rubs me the wrong way. I'm tempted to just personally reverse engineer each existing PDF and draw every line and character myself before adding the user-inputted text, but I wanted to check to see if there was an easy way to take an existing PDF and set it as a background for some extra text. I'd really prefer to use python as it's the only language I feel comfortable with. I also realize that I could just scan the document itself and use the resulting raster image as a background, but I would prefer the precision of vector graphics. It seems like ReportLab has a commercial product with this functionality, and the specific function I'm looking for is in it (copyPages) - but it seems like overkill to pay for a 4 figure product for a single, simple function for a nonprofit use.

  • How to split a string by ',' or '[|]' unless the ',' is in '{}'

    - by floyddotnet
    i search for a regex to split the following string: aaa[bbb,ccc[ddd,{eee:1,mmm:999}],nnn[0,3]] aaa[bbb,ccc[ddd,{eee:1, mmm:[123,555]}],nnn[0,3]] aaa[bbb, ccc[ddd, ddd],nnn[0,3]] aaa[bbb,ddd[0,3]] by '[' or ']' or ',' unless the ',' is in '{}'. As example: split 'aaa[bbb,ccc[ddd,' to aaa, bbb, ccc, ddd is allow but not {eee:1,mmm:999}. the result: aaa, bbb, ccc, ddd, {eee:1,mmm:999}, nnn, 0, 3 aaa, bbb, ccc, ddd, {eee:1, mmm:[123,555]}], nnn, 0, 3 aaa, bbb, ccc, ddd, ddd, nnn, 0, 3 aaa, bbb, ddd, 0, 3 i have read meany other questions but i cant modifie the regex's there are post to do this what i want. the target language for the expression is javascript.

  • learning OO with PHP

    - by dole doug
    Hi there I've started to learn OO programming, but using the PHP language with the help of the "PHP 5 Objects, Patterns, and Practice" book. The thing is that I wish to learn to use into same time the CakePHP framework which make use a lot of the MVC pattern. Because I don't know much about OO and less about MVC I wish to understand the later one but assumptions I make with my OO knowledges might have bad impact on long term. Does anyone know a good tutorial about what means MVC (more than cakephp manual says about it, but more easy to read/understand than wikipedia)? TY

  • What technical skills needed for algorithmic trading, HFT, etc?

    - by alchemical
    I'm interested in getting into developing trading systems, black box, HFT, etc. My primary experience is with C# and .Net (7 years). I've also done some sockets programming. I have some experience in finance working on analysis applications (2 years). My goal is to move into developing automated trading systems for a hedge fund, bank, etc. Is there any way to learn the skills needed for this without somehow getting the job first? I've looked at the open source tradelink, IB interactive brokerage, etc. I'm playing around with this framework, and may hook it up and do some paper trading. However, I'm not sure if this has much relationship with how a well-funded entity would be conducting a high-level automated trading operation. I.e. would the tools and frameworks they prefer be a totally different skill-set? Also wondering if I need to learn C++ and/or Java for these types of apps.

  • Where is a good place for a code review?

    - by Carlos Nunez
    Hi, all! A few colleagues and I created a simple packet capturing application based on libpcap, GTK+ and sqlite as a project for a Networks Engineering course at our university. While it (mostly) works, I am trying to improve my programming skills and would appreciate it if members of the community could look at what we've put together. Is this a good place to ask for such a review? If not, what are good sites I can throw this question up on? The source code is hosted by Google Code (http://code.google.com/p/nbfm-sniffer) and an executable is available for download (Windows only, though it does compile on Linux and should compile on OS X Leopard as well provided one has gtk+ SDK installed). Thanks, everyone! -Carlos Nunez

  • SCSI Windows Setup on Dell Precision 670 Workstation...please help.

    - by sweetcoder
    Error Windows Setup: "setup did not find any hard disk drives installed in your computer" This is not exactly a programming question but I thought you guys might be able to help. I just received a Dell Precision 670 workstation. Windows is not recognizing the hard drive and I have experienced this before with other computers. I usually would just go in the bios and set the configuration to compatibility mode. I have no idea how to do this on this machine. There is this Adaptec SCSI HostRaid BIOS v4.30.4S5 screen on startup. It says to press CTRL A for SCSI select utility. It shows a Maxtor ATLAS10K5_73WLS for the drive. I was wondering if anyone out there knew how to configure this thing so that windows setup will recognize the hard drive? Any advice is very much appreciated and if you have to know further information please let me know. Raid was turned off in the BIOS for this device. TY

  • Communicating with the PC via USB connection in Android

    - by Danny Singh
    I'm fairly new to android programming and need some information for a 4th year forensics course project. Basically I am trying to create a suite of tools for live analysis of an android phone. I know how to get the information I need on the phone, but I was wondering if there was a way to communicate that information back to the PC? I want to be able to run a program from a PC, which, when the phone is docked, will allow the user to access information about the phone (ie currently running services/processes, bluetooth/wifi connections, etc). I have a bunch of methods that will run on the phone and get all the information, but I want to be able to call those methods from the PC, execute on the phone, then have the information sent back to the PC to display to the user instead of just displaying it on the phone. This is to leave as small a footprint on the phone as possible. Thanks a lot.

  • Bison: Optional tokens in a single rule.

    - by Simone Margaritelli
    Hi there .. i'm using GNU Bison 2.4.2 to write a grammar for a new language i'm working on and i have a question. When i specify a rule, let's say : statement : T_CLASS T_IDENT '{' T_CLASS_MEMBERS '}' { // create a node for the statement ... } If i have a variation on the rule, for instance statement : T_CLASS T_IDENT T_EXTENDS T_IDENT_LIST '{' T_CLASS_MEMBERS '}' { // create a node for the statement ... } Where (from flex scanner rules) : "class" return T_CLASS; "extends" return T_EXTENDS; [a-zA-Z\_][a-zA-Z0-9\_]* return T_IDENT; (and T_IDENT_LIST is a rule for comma separated identifiers). Is there any way to specify all of this only in one rule, setting somehow the "T_EXTENDS T_IDENT_LIST" as optional? I've already tried with T_CLASS T_IDENT (T_EXTENDS T_IDENT_LIST)? '{' T_CLASS_MEMBERS '}' { // create a node for the statement ... } But Bison gave me an error. Thanks

  • Does Blogging affect Job Prospects?

    - by BM
    Would a hiring manager at a small-to-medium consulting firm/corporation consider active blogging by a candidate about Programming/software/technology as a positive? Should the candidate disclose this information during the interviews or put it on the resume? Thanks for the answers, So far the views about this topic has been.. Don't mention the blog if it is not relevant to the job. Mention the blog, if you believe your blog has quality content. Potential risk of not being accepted by culture of the employer's workplace. Could be a valuable for consultants to publish & preview their skills and experience. Certain Employers may consider blogging of a candidate a plus. Be careful what you post on the blog,no badmouthing,rants and overt criticism of others. Do not lie about blogging,if directly asked during the interview.

  • Hiding a dropdown menu without it flashing with prototype

    - by TenJack
    I have a number of dropdowns and divs that are hidden when the page loads and can be toggled with a click or mouseover, but some of them flash b/c the javascript does not run in time. I have their display initially set to block and then I use javascript/prototype to find the element and hide it. I have tried loading these "hider" functions using dom:loaded but there is still flashing. This is an example of a dropdown prototype initialization funtion. From http://www.makesites.cc/programming/by-makis/simple-drop-down-menu-with-prototype/: var DropDownMenu = Class.create(); DropDownMenu.prototype = { initialize: function(menuElement) { menuElement.childElements().each(function(node){ // if there is a submenu var submenu = $A(node.getElementsByTagName("ul")).first(); if(submenu != null){ // make sub-menu invisible Element.extend(submenu).setStyle({display: 'none'}); // toggle the visibility of the submenu node.onmouseover = node.onmouseout = function(){ Element.toggle(submenu); } } }); } }; Is there a better way to hide div's or dropdowns to avoid this flashing?

  • What useful GDB scripts have you used/written?

    - by nik
    People use gdb on and off for debugging, of course there are lots of other debugging tools across the varied OSes, with and without GUI and, maybe other fancy IDE features. I would like to know what useful gdb scripts you have written and liked. While, I do not mean a dump of commands in a something.gdb file that you source to pull out a bunch of data, if that made your day, go ahead and talk about it. Lets think conditional processing, control loops and functions written for more elegant and refined programming to debug and, maybe even for whitebox testing Things get interesting when you start debugging remote systems (say, over a serial/ethernet interface) And, what if the target is a multi-processor (and, multithreaded) system Let me put a simple case as an example... Say, A script that traversed serially over entries to locate a bad entry in a large hash-table that is implemented on an embedded platform. That helped me debug a broken hash-table once.

  • Building webparts with Visual Studio 2010 Express

    - by MalphasWats
    Hi, I'm trying to get started with building my own webparts, planning to follow this MSDN article. I've downloaded Visual C# 2010 Express - I'm not quite at the point where I feel comfortable dropping 1000 big ones yet, and I installed Visual Web Developer 2010 Express via the WPInstaller. Following through the tutorial, aside from the fact that I don't get the option to create a "Web Control Library", a gap I filled with this article, I can't seem to find the sn.exe tool (or the "Visual Studio 2005 Command Prompt"!). I know it's not quite a direct programming related question, but I can't even get the thing going yet! Any help is appreciated. Thanks EDIT:- I think I may be jumping the gun quite considerably, I wrote a simple hello world example and tried to build it but it doesn't have any references to the Microsoft.SharePoint packages and they don't appear in my lists. Am I understanding some more research I've done (namely this) correctly, in that I have to actually have a full installation of actual SharePoint on the machine I'm developing on?

  • Most mind-blowing C++ hack you've ever seen?

    - by sblom
    In the same spirit as the "Hidden features of X?" series, what are the most mind-blowingly well-executed "I didn't even think the language could do that!" hacks that you've ever seen in C++. For example, my recent favorite is an implementation of the "operator" --> for pre-C++0x lambdas. Another fantastic example is Multi-dimensional analog literals. (Note: this is a community wiki question to avoid the appearance of reputation-whoring.)
