  • Simplyfing code with a lot of ifs

    - by user278618
    I have a method which based on the enum, and to be clear at start we have this situation: public void MyMetohd(Somestatus status) { if(status == Somestatus.Enum1) { DoA(); DoB(); DoC(); DoD(); DoE(); } if(status == Somestatus.Enum2) { DoA(); DoB(); DoC(); DoD(); } if(status == Somestatus.Enum3) { DoA(); DoB(); DoC(); } if(status == Somestatus.Enum4) { DoA(); DoB(); } if(status == Somestatus.Enum5) { DoA(); } } How would you optimize this kind of code ( it isn't mine)?

  • Where should I store my App specific config files in WPF

    - by Akash Deshpande
    Background : I have some Application Data. i.e. the Database, come important config files. This data is vital for the application to start else it is exited. Problem : Where should I store this data. i.e in which folder and where. Right Now (This is wrong) it is stored in a folder in Debug/App_Data. But is causing issues in git and when we publish the App the data is not found. So where can we store this folder ? Present Structure is "WpfApplication2\WpfApplication2\bin\Debug" These Files need to be present when the app is started. So they need to be a part of the app itself.

  • How should I think about perspectives and rotation in OpenGL ES?

    - by Omega
    As I start to write rendering code, how do I want to consider my drawing operations? Will they always be relative to a fixed coordinate system on the screen, or does this change based on the camera perspective? The best example I can try to come up with is say I'm at (0,0,0) and I draw a line to (3,3,3). If I change the perspective +1 on the X axis and conduct the same operation, does it happen at (4,3,3), or am I just getting a new view of the line still being made at (3,3,3)? When doing rotation, am I moving the point from which a frustum emanates, or am I moving the rendering underneath?

  • extract number of A tags using jquery

    - by user1017268
    I am working on an enterprise application where I can have several links present in table or none depending on the data. The links appear in the table and have following code behind them <td class="Row"><span id='s_3_2_14_0' ><a href='JavaScript:SWETargetGotoURL("/eservice_enu/start.swe?SWECmd=GotoView&SWEView=Active+PO+Serial+View&SWEPostnApplet=Purchase+Order+List+Applet&SWEPostnRowId=1-KPBLOZ","_self")'>2001103009</a></span></td> I need to find all the A tags present in the page inside SPAN tag having following text SWEView=Active+PO+Serial+View&SWEPostnApplet=Purchase+Order+List+Applet I tried the following expression but it returns 0 $('a[href*="SWEView=Active+PO+Serial+View&SWEPostnApplet=Purchase+Order+List+Applet"').length;

  • Sliding & Fading controls on a C# form

    - by Tommy
    Hey there, I'm trying to implement a way to slide&fade controls around (more than one at the same time possibly) elegantly. So in other words, say i had a picture in the top left corner, and a texbox in the bottom right corner, i'd like to be able to have them slide. not just snap. slide, to the opposite corners and replace eachothers position. Ive been working for awhile but have not come up with anything efficient, even just some of the basic math calculations would be a great start.

  • Passenger problem: "no such file to load" -- /config/environment

    - by Mason Jones
    I've been researching this one and found references to similar problems here and there, but none of them has led to a solution yet. I've installed passenger (2.2.11) and nginx (0.7.64) and when I start things up and hit a Rails URL, I get an error page informing me of a load error: no such file to load -- /path/to/app/config/environment From what I've found online this appears to be some sort of a user/permissions error, but I've tried all the logical fixes: I've made sure that /config/environment.rb is not owned by root, but by a webapp user. I've tried setting passenger_default_user, I've tried setting passenger_user_switching off. I've even tried setting the nginx user, though that shouldn't matter much. I've gotten some differing results, but nothing's actually worked. I'm hoping someone may have the magical combination of settings and permissions for this. I may try backing down to an earlier version of Passenger, because I've never had this issue before; it's been a little while since I set up Passenger though. Thanks for any suggestions.

  • Separate groups of objects based on their properties

    - by Bevin
    I want to separate an array of my custom object into several arrays, based on the values of their two properties. The struct looks like this: struct MyStruct { public string Person { get; set; } public string Command { get; set; } } Now, if I have an array with a few objects: {Person1, cmd1} {Person1, cmd3} {Person2, cmd3} {Person3, cmd2} {Person2, cmd4} I want to be able to place them into one array for each person, that lists all of the commands for that person: {Person1: cmd1, cmd3} {Person2: cmd3, cmd4} {Person3: cmd2} I hope I've made it clear with my descriptions. I would assume that there is an elegant way to do this with LINQ, but I have no idea where to start.

  • crtmqm give no response

    - by Willy
    Hi all, I try to create a WebSphere queue manager in production env. Before this I manage to create the queue manager in the development env with no problem. I'm using this script to create the queue manager: crtmqm -u SYSTEM.DEAD.LETTER.QUEUE test1.qm But it give no response (no error or success message). When I try to start the queue manager (strmqm test1.qm) it give "AMQ8118: WebSphere MQ queue manager does not exist." Then I notice lots of strange thing that supposed not happen: I can run the "crtmqm -u SYSTEM.DEAD.LETTER.QUEUE test1.qm" several times without any error I can just type crtmqm and got no response I can type crtmqm -y (which is not possible since there is no -y argument) and still no response Can anyone tell me what is wrong?

  • XML Architecture

    - by Roflcoptr
    For my application I have to use a undefined number of different detection strategies. A strategy is defined in the following fashion: The AND gate can also be a OR gate. For now, I hard coded all these rules in my code. For better extensability, I'd like to define all the detection startegies respectively rules in a XML file and parse it. But I'm not really sure how I can define such a detection strategy in a XML file. Any hints how to start?

  • Tomcat application: Frequent OutOfMemory PermGen exception while image uploads

    - by rabbit
    Hi, I have a tomcat 6 application which I have set parameters of -Xms512m -Xmx1024m. I thought 1 GB of memory in a 4 GB RAM would be enough, but that is not the case. On application stop/start multiple times (from tomcat manager) and also on image uploads (sometimes) I run into the OutOfMemory PermGen space error and the site stops responding. Should I increase the memory still some more? Is there anything else that I can do to from the tomcat side so that it does not run into the PermGen space issue? Thanks in advance for pointers/tips etc.

  • Exponential volume control with a specified midpoint

    - by Lars
    I have a slider that returns values from 0 to 100. I am using this to control the gain of an oscillator. When the slider is at 0, I would like the gain to be 0.0 When the slider is at 50, I would like the gain to be 0.1 When the slider is at 100, I would like the gain to be 0.5 So I need to find an equation to get a smooth curve which passes through all of these points. I've got the following equation which gives an exponential curve and gets the start and end points correct, but I don't know how to force the curve through the middle point. Can anyone help? function logSlider(position){ var minP = 0; var maxP = 100; var minV = Math.log(0.0001); var maxV = Math.log(0.5); var scale = (maxV - minV) / (maxP - minP); return Math.exp(minV + scale*(position-minP)); }

  • How to measure Silverlight or Flash control load time with Google Analytics

    - by ddehghan
    Hi everyone I have a simple silverlight page for for finding available domain names. This problem is equaly valid for a flash control as well. I use Google Analytics for monitoring the traffic. I would like to find out how long it take for users to download and render the Silverlight control. Once the java script on a page is loaded there should be a way to start a timer and then stop the timer once the Silverlight/flash control is loaded. Key points I would like to measure are: Time it takes to download the silverlight/flash control Time it takes to initialize the control Thanks

  • Tips about a good class-structure for website? (php)

    - by Martti Laine
    Hello I'm creating a kind of massive network for users to register and login. I want to try using classes, but I've never used them (expect some mysql-wrappers etc). Could you provide some tips and sample-structure for my project? The idea is to simply have a index.php, which prints the whole page and does all the action. Index.php calls functions from classes inside other files. I need: user-class for checking if logged in and retrieving user-info different kind of "page"-classes for functions needed in those pages I'm not asking for full code, but just a start. I don't know, how to use public functions or anything like that. How to wrap these classes to work together? So no functions, just the structure! Martti Laine

  • Scoping two models on approved

    - by Shaun Frost Duke Jackson
    I have three models (Book,Snippet,User) and I'd like to create a scope for where(:approved = true) I'm doing this so I can use the merit gem to define ranking based on count of approved. I'm thinking that writing this as a scope might be to complex but I don't know as I've just started leaning scopes. I've currently got this in my Book & Snippet Model: scope :approved, -> { where(approved: true) } I've playing around with this in my user model but I don't think it's correct: scope :approved, joins(:books && :snippets) Could anyone help start me off or give me some suggestions on what to read?

  • Starting socket server in ruby on rails on cloud environments (heroku)

    - by ElTren
    Hi, I'm using heroku, and I can push a Ruby on Rails app just fine, I'm trying to convert this to a Socket server, basically I would need to bind to an open port, in this case, I know Heroku only does 80 22 and 443. Is it possible to bind to port 80 on those environments? Also, how would I setup the entry point for this socket server, all I know is that when script/server it boots up the app. Do I have to put the function call there? How can a socket server start instead of the rails app on top of whatever webserver heroku has.

  • Flash CS5 AS3 drop shadow filter won't print

    - by Blake uburuDOTcom
    Hello all, I've tried searching quite a bit to discover why I don't seem to be able to print drop shadow filters from within Flash. I have trouble printing, but if the movieclip I want to print has or contains a drop shadow, that clip will print sans the drop shadow. Anyone have any insight as to why this might be happening? If you want to try it out yourself, here is the simple print code I'm using. Just put something inside contentmc with a dropshadow and print it. print_btn.addEventListener(MouseEvent.CLICK,printContent); function printContent(evt:MouseEvent) { var printJob:PrintJob = new PrintJob(); if (printJob.start()) { if (content_mc.width>printJob.pageWidth) { content_mc.width=printJob.pageWidth; content_mc.scaleY=content_mc.scaleX; } printJob.addPage(content_mc); printJob.send(); } }

  • Import small number of records from a very large CSV file in Biztalk 2006

    - by rwmnau
    I have a Biztalk project that imports an incoming CSV file and dumps it to a database table. The import works fine, but I only need to keep about 200-300 records from a file with upwards of a million rows. My orchestration discards these rows, but the problem is that the flat file I'm importing is still 250MB, and when converted to XML using a regular flat file pipeline, it takes hours to process and sometimes causes the server to run out memory. Is there something I can do to have the Custom Pipeline itself discard rows I don't care about? The very first item in each CSV row is one of a few strings, and I only want to keep rows that start with a certain string. Thanks for any help you're able to provide.

  • Excel Worksheet assignment in VB.Net doesn't compile

    - by Brian Hooper
    I'm converting a VB6 application into VB.Net and having trouble with the basics. I start off with:- Dim xl As Excel.Application Dim xlsheet As Excel.Worksheet Dim xlwbook As Excel.Workbook xl = New Excel.Application xlwbook = xl.Workbooks.Open(my_data.file_name) xlsheet = xlwbook.Sheets(1) but the last line doesn't compile; it reports Option Strict On disallows implicit conversion from 'Object' to 'Microsoft.Office.Interop.Excel.Worksheet' I can make this go away by replacing the line with xlsheet = CType(xlwbook.Sheets(1), Excel.Worksheet) but that does't look like the right thing to do to me. If the assignment is correct, I would have thought the object should naturally have the correct type. So: does anyone know what the correct thing I should be doing here?

  • Running applictions via ruby and multi-core support? (OSX)

    - by Nick Faraday
    Hi All, I'm looking for some tutorials/resources/tips that will show me how to run applications via a ruby script. I have several small tools that we use in our day to day operations that I want to manage their tasks in one ruby script. Basically what I'm trying to do is: run app via ruby script. (wait for result) get result code (success, or error msg) if ok, start the app on its next task. Also each of the tasks are independent so I'd like to take advantage of the 8 cores on my MacPro and run 8 instances at a time. Any resources you could point me towards would be greatly appreciated!

  • How do I test switching compilers from MSVS 6 to MSVS 2008?

    - by Leif
    When switching from MSVS 6 to MSVS 2008, what major differences should I look for when testing the software? I'm coming from more of a QA perspective. We have two programs that work closely together that were originally compiled in Visual C++ 6. Now one of the programs has been compiled in Visual C++ 2008 in order to use a specific CD writing routine. The other program is still compiled under MSVS 6. My manager is very concerned with this change and wants me to run tests specific to this change. Since I deal more with QA and less with development, I really have no idea where to start. I've looked for differences between the two, but nothing has given me a clear direction as far as testing is concerned. Any suggestions would be helpful.

  • .NET platform independant sync framework

    - by Quandary
    Question: I need to synchronize a few ActionScript files from my computer to a network share (backup). I saw a quick fix would be using Microsoft Sync Framework for this, and write a windows service. My problem is I also use Linux, and before I start with MS vendor lockin, is there any sync framework/library/whatever I could use that works accross platform? Or does the MS sync framework work on Linux, too? It is my understanding that it is a wrapper around some com objects, thus it wouldn't work. All I need is synchronizing files. So never mind the database part, although it would be nice to have it, too.

  • TCP 30 small packets per second polutes connection with server

    - by Denis Ermolin
    I'm testing connection with flash client and cloud server(boost::asio for software) over TCP connection. My connection with server already is really poor - 120 ms ping in average. I found when i start to send packets with 2 bytes size (without tcp header) with speed 30 packets/s ping grow to 170-200 average. I think that it's really bad and my bad connection and bad cloud provider is reason for this high ping without any load. What do you think? (I tested my software and can compute about 50k packets/s so software is not a problem).

  • Advise on starting a new job

    - by Sisiutl
    I hope this isn't too off-topic, but in a week I will start a new job at a manufacturing company managing the development of a new eCommerce site. The company scores about a 3 on the "Joel" test. I will inherit 3 programmers who developed the company web site and do general IT programming. I have the grey hair and credentials to have their initial respect but I'm an engineer, not a manager. I'm looking for practical advise - particularly for the first 90 days - on how to establish myself, keep the team together, and move forward.

  • Server-side Audio Editor

    - by Kristen
    I am looking for an audio editor that we can use server side (ASP + IIS) We want users to be able to upload an audio file, and then offer a 10 second teaser clip to other users for download. Ideally I would like our application to be able to specify Input and Output Filename, Start and End time (or Duration), and be able to fade-in and fade-out, and equalise the volume. Maybe some audio editors have a batch edit facility, and it would just be a question of installing on the server? All the keywords I have tried putting into Google have led me on a wild goose chase, hopefully someone can help me with suggestions. Thanks.

  • PHP/codeigniter - use of exit()

    - by Patrick
    I have a few pages that require login, so all controllers that link to these pages start with $this->checkSession(); //...rest of the code CheckSession should verify the session is still live, otherwise display a message and stop the execution of the rest of the code in the controller: function checkSession() { if (!$this->session->userdata('is_logged_in')) { //the session has expired! $data['main'] = 'confirmation_message'; $data['title'] = "Session expired"; $this->load->vars($data); $this->load->view('template'); exit(); } } . I was expecting these instructions to happen in sequence, but I only get a blank page. How can I make sure exit() gets executed only after all views are loaded?
