• Few question about client application to be networked

  - by user225269

  I have made a registration program. Making use of mysql database. Can I still use the traditional programming for client applications. If I want to network it. Do I have to modify the codes a little in order to make it work? -Please enlighten me, I'm just a beginner. I don't have any idea on how this works. Do I have to install wampserver only in one computer? I'm using visual studio 2008. Win forms to be exact.

• How to establish a two-way communication between Activity and Service in different process?

  - by steff

  Hi everyone, I'm working on establishing a two-way communication between an Activity and a Service which runs in a different process. Querying the process from the Activity is no big deal. But I want the process to notify the Activity on events. The idea behind it is this: the service runs independently from the actual app. It queries a webserver periodically. If a new task is found on the webserver the process should notify the activity. I found this thread over at AndDev.org but it doesn't seem to work for me. I've been messing around with BroadcastReceiver. I've implemented an interface which should notify the Activity but the problem is that the listener is always null since the Broadcast from the process is done via Intent, hence the class that extends BroadcastReceiver will be newly instantiated. How can I establish a 2-way communication? This has to be possible. Thanks for any help, steff

• How do i serve shortcuts/.lnk from web servers?

  - by acidzombie24

  without using a database i wanted a file to point to the newest revision of a file. Someone suggested using a shortcut. Knowing i can rewrite file.ext to file.ext.lnk i thought it was a great idea. Then i tried it, my server (VS 2010rc) serves the shortcut rather then the file. Not what i wanted... How do i serve the file the shortcut is pointing to? NOTE: I am planing to use windows 2008 as my server so a solution should work on that as well. The OS i am running is windows 7.

• MOSS 2007 - Using Connectable WebPart - Consumer has TextBox

  - by JohnP

  I have 2 webparts which are connected, where the provider sends a string to the consumer. However it fails to work if I put any TextBox controls in the consumer webpart. (works fine if I use a Label or Literal control. The idea is that the consumer is to be composed of form controls like TextBoxes. e.g. the codeproject sample at http://www.codeproject.com/KB/sharepoint/ConnectingCustomWebParts.aspx Works fine... until you replace the consumer Label control with a TextBox. Any help gratefully received.

• MYSQL Event to update another database table

  - by Lee

  Hey All, I have just taken over a project for a client and the database schema is in a total mess. I would like to rename a load of fields make it a relationship database. But doing this will be a painstaking process as they have an API running of it also. So the idea would be to create a new database and start re-writing the code to use this instead. But I need a way to keep these tables in sync during this process. Would you agree that I should use MYSQL EVENT's to keep updating the new table on Inserts / updates & deletes?? Or can you suggest a better way?? Hope you can advise !! thanks for any input I get

• Rewriting Live TCP Streams

  - by user213060

  I want to rewrite TCP/IP streams. Ettercap's etterfilter command lets you perform simple live replacements of TCP/IP data based on fixed strings or regexes. Example: http://ettercap.sourceforge.net/forum/viewtopic.php?t=2833 I would like to rewrite streams based on my own filter program instead of just simple string replacements. Anyone have an idea of how to do this? Is there anything other than Ettercap that can do live replacement like this, maybe as a plugin to a VPN software or something? Thanks!

• Binding the property to a control defined inside a listboxitem template

  - by Malcolm

  I have a class called ledgerObject : public class LedgerObject { public ChargeLine ChargeLine{ get; set; } public DelegateCommand Click_hyperbnCommand{ get; private set; } public LedgerObject() { this.Click_hyperbnCommand = new DelegateCommand(click_btn); } private void click_btn(object args) { } } The chargeLine which is the property of this class is itself a class and has some properties in it. So I am binding the datacontext of a listbox to an array of LedgerObject, and I want to bind the textblock control defined inside a listboxitem template to the property of a ChargeLine. Any idea or suggestion will help. I have tried this but not working: <TextBlock Margin="4 0 4 0" Grid.Column="3" Text="{Binding Path=ChargeLine.SimCode}" TextDecorations="Underline" Foreground="Red" />

• LINQ: Dot Notation vs Query Expression

  - by Martín Marconcini

  I am beginning to use LINQ in general (so far toXML and toSQL). I've seen that sometimes there are two or more ways to achieve the same results. Take this simple example, as far as I understand both return exactly the same thing: SomeDataContext dc = new SomeDataContext(); var queue = from q in dc.SomeTable where q.SomeDate <= DateTime.Now && q.Locked != true orderby (q.Priority, q.TimeCreated) select q; var queue2 = dc.SomeTable .Where( q => q.SomeDate <= DateTime.Now && q.Locked != true ) .OrderBy(q => q.Priority) .ThenBy(q => q.TimeCreated); Besides any mistake I may have made in the syntax or a missing parameter or difference, the idea is that there are two ways to express the same thing; I understand that the first method has some limitations and that the "dot notation" is more complete, but besides that, are there any other advantages?

• Looking for design/architecture suggestions for a simple HTML game.

  - by z-boss

  Imagine that HTML page is a game surface (see picture). User can have n number of boards (blue divs) on his page. Each board can be moved, re-sized, relabeled, created new and removed. Inside each board there are m number of figures (purple divs). Each of these user can move inside the board or to another board, re-size, change color and label, delete, add new. The goal of the game is not important, but let's say it is to rearrange figures in a certain way so that they disappear. But the goal of the programmer is to save the whole game surface in the database for every user of the site, and to load it later when he returns. So, how do I go about data exchange between client and the database? I'll give my idea in one of the answers.

• Advantage of using a static member function instead of an equivalent non-static member function?

  - by jonathanasdf

  I was wondering whether there's any advantages to using a static member function when there is a non-static equivalent. Will it result in faster execution (because of not having to care about all of the member variables), or maybe less use of memory (because of not being included in all instances)? Basically, the function I'm looking at is an utility function to rotate an integer array representing pixel colours an arbitrary number of degrees around an arbitrary centre point. It is placed in my abstract Bullet base class, since only the bullets will be using it and I didn't want the overhead of calling it in some utility class. It's a bit too long and used in every single derived bullet class, making it probably not a good idea to inline. How would you suggest I define this function? As a static member function of Bullet, of a non-static member function of Bullet, or maybe not as a member of Bullet but defined outside of the class in Bullet.h? What are the advantages and disadvantages of each?

• Line of code doesnt follow sequential execution

  - by ryudice

  Hi, I'm having a problem with a code that doesnt follow sequential execution although I'm not using threading. My code calls one function and when I'm debugging inside the function, it returns to the line of code following the function call although the function hasnt finished executing, I have no idea why this would happen, any ideas? thanks in advance. workflow.SaveControlTiempo(solEntity, traId, Usuario.GetUsrId());// this is my function RadAjaxManager.GetCurrent(Page).RadAlert("Solicitud Transicionada con \u00c9xito"); // code execution continues here even if the function hasnt finished and since the function hasnt finished I get an exception var javascripFunction = "CloseWindow('Solicitud <b>{0}</b><br />Transicionada con \u00c9xito.<li> <b>Etapa Destino: </b>{1}<li><b>Usuario: </b>{2}');"; javascripFunction = string.Format(javascripFunction, solEntity.SOL_CODIGO, solEntity.WKF_ETP_ETAPAS.ETP_DES, DNNUtil.GetInstance().GetUserName(solEntity.USR_ID));

• Justified navigation buttons

  - by Kaivosukeltaja

  I'm trying to create the primary navigation menu for a website that will have a variable amount of primary menu items. The navigation bar is horizontal and has a width of 738px. I would like to have the leftmost item 18px from the left and the rightmost item 18px from the right edge of the element, with the other menu items spread evenly between them. I'm using a tableless layout. So far I haven't been able to make it work exactly like I want. Setting margin: auto doesn't seem to help, and I can't keep the 18px margin on both sides using a table. One idea was to use text-align: justify but it doesn't justify single lines. Is there a simple or less simple way of doing this, or am I going to have to ask the AD to relax his visual requirements?

• Database designing for a bug tracking system in SQL

  - by Yasser

  I am an ASP.NET developer and I really dont do such of database stuff. But for my open source project on Codeplex I am required to setup a database schema for the project. So reading from here and there I have managed to do the following. As being new to database schema designing, I wanted some one else who has a better idea on this topic to help me identify any issues with this design. Most of the relationships are self explanatory I think, but still I will jot each one down. The two keys between UserProfile and Issues are for relationships between UserId and IssueCreatedBy and IssueClosedBy Thanks

• Div that should take up the "rest of the page" expands beyond the page in ie.

  - by Clox

  Okay, this is REALLY starting to bug me... This page works fine in both Chrome and Firefox. www.bloggan.tk But if it's opened in internet-explorer it always expands beyond the page and introduces the scrollbar no matter what the resolution of the browser is. I have NO idea what change in the html it was that cause this... Here's the blogger-template-html-source I'd REALLY appreciate if someone could help me with this. Thanks in advance! Edit: I've "solved" it for IE using javascript, but that's only temporary (i hope). The version without javascript can be seen here, so that you still will be able to know what I'm talking about. Still trying to solve it, and still hoping for someone to help me.

• Adding Listeners at runtime? - Java MVC

  - by Halo

  My model in my MVC pattern, generates components at runtime and gives them to the View to be displayed on the screen through update() method (you know, model is the observable and the view is the observer). But I also need to add listeners to these components, and the controller has the listener methods (because they say the MVC pattern is like this) and it's not involved in this update process. So I can't add the listeners at runtime, but only in the controller's constructor at startup. I've got an idea, that is making the controller the observer and then giving the data to the view, as well as adding the listeners. Do you think this would be OK?

• Best way to store large dataset in SQL Server?

  - by gary

  I have a dataset which contains a string key field and up to 50 keywords associated with that information. Once the data has been inserted into the database there will be very few writes (INSERTS) but mostly queries for one or more keywords. I have read "Tagsystems: performance tests" which is MySQL based and it seems 2NF appears to be a good method for implementing this, however I was wondering if anyone had experience with doing this with SQL Server 2008 and very large datasets. I am likely to initially have 1 million key fields which could have up to 50 keywords each. Would a structure of keyfield, keyword1, keyword2, ... , keyword50 be the best solution or two tables keyid keyfield | 1 | | M keyid keyword Be a better idea if my queries are mostly going to be looking for results that have one or more keywords?

• What is Boost missing?

  - by Robert Gould

  After spending most of my waking time on Stack Overflow, for better or for worse, I've come to notice how 99% of the C++ questions are answered with "use boost::wealreadysolvedyourproblem", but there must definitely be a few areas Boost doesn't cover, but would be better if it did. So what features is Boost missing? I'll start by saying: boost::sql (although SOCI should try to become a legal part of boost) boost::json (although TinyJSON should try to become a legal part of boost) boost::audio (no idea about a good boost-like C++ library) PS: The purpose is to compile a reasonable list, and hopefully Boost-like solutions out there that aren't yet a part of Boost, so no silly stuff like boost::turkey please.

• Is there a reason why a submit button would fail in ie6 using jquery?

  - by kgrad

  I have a form being submit to a servlet, there is a jQuery Datepicker on the page. On some computers using ie6, for some reason the page is crashing on submit. I am getting a 404 error, but only sometimes. I have no idea why this would occur. My theory is that somehow it's bypassing the servlet, or its not loading jquery properly, or... I am at a loss. What are some reasons why this could occur on some computers? The exact version of ie6 is 6.0.2900.2180, on windows XP SP2. How can I test with this specific version?

• writing a fast parser in python

  - by panzi

  I've written a hands-on recursive pure python parser for a some file format (ARFF) we use in one lecture. Now running my exercise submission is awfully slow. Turns out by far the most time is spent in my parser. It's consuming a lot of CPU time, the HD is not the bottleneck. I wonder what performant ways are there to write a parser in python? I'd rather not rewrite it in C. I tried to use jython, but that decreased performance a lot! The files I parse are partially huge ( 150 MB) with very long lines. My current parser only needs a look-ahead of one character. I'd post the source here but I don't know if that's such a good idea. After all the submission deadline has not jet ended. But then, the focus in this exercise is not the parser. You can choose whatever language you want to use and there already is a parser for Java.

• What are some topics you'd like to see covered in an 'Introduction to Network Security' book?

  - by seth.vargo

  I'm trying to put together a list of topics in Network Security and prioritize them accordingly. A little background on the book - we are trying to gear the text towards college students, as an introduction to security, and toward IT professionals who have recently been tasked with securing a network. The idea is to create a book that covers the most vital and important parts of securing a network with no assumptions. So, if you were a novice student interested in network security OR an IT professional who needed a crash course on network security, what topics do you feel would be of the upmost importance in such a text?

• What can I use for voluntary donations? (like Tipjoy)

  - by Ken

  There used to be a site called Tipjoy that would let me put a small "donate" button on a webpage, and users could donate small amounts (like 25c) to me easily. I think it was a pretty neat idea, since I want to have a way for people to give me money, and I don't like advertisements, and I don't update regularly enough to sell subscriptions like bloggers. I just have some simple web services and open-source program and I want an easy way for people to drop me some change if they think they're useful. I've found out that Amazon used to have a similar service, but it's also been shut down. Is there any similar web service available today? If not, what's the closest thing to offer -- a Paypal link?

• Relationship Modelling in Core Data

  - by Stevie

  Hi there, I'm fairly new to Objective C and Core Data and have a problem designing a case where players team up one-on-one and have multiple matches that end up with a specific result. With MySQL, I would have a Player table (player primary key, name) and a match table (player A foreign key, player B foreign key, result). Now how do I do this with Core Data? I can easily tie a player entity to a match entity using a relationship. But how do I model the inverse direction for the second player ref. in the match entity? Player Name: Attribute Match: Relationship Match Match Result: Attribute PlayerA: Relationship to Player (<- Inverse to Player.Match) PlayerB: Relationship to Player (<- Inverse to ????) Would be great if someone could give me an idea on this! Thanks, Stevie.
