• GTK+ with any programs

  - by user565739

  I recently knew a latex-editor "gummi", see http://gummi.midnightcoding.org/ , which is written by GTK+ graphical interface toolkit. There are two panels, one in the left which is an editor (using the library gtksourceview) and on in the right which is a viewer (using the library poppler). I am curious that if we can do similary things for every program. For example, replace the editor with "terminal"?"emacs"?"vim"?"terminator (a multi-windows terminal)"...etc. And replace the viewer with other viewers, which in my mind is Adobe Reader. With discussion with the author, he mentioned: The viewer component is also replacable, but doing it with Adobe Reader would not be easy or perhaps even impossible. The reason for this being that Adobe Reader is a complete program instead of a library, and also closed-source So I have some questions: a) We can only make "library" embedded as a panel, but we can't do this for a (any) program? b) Could we replace the editor with emacs? with terminal? c) Could we replace the viewer with Adobe Reader? If not, why? Because it's a program or it's closed-source? I know the questions in this thread are not very precise, sorry.

• Making a Delete and Reply button in Jquery

  - by Branko Ostojic

  this is my second post on the website. Of all other sites i tried, this one gave the most accurate and useful information! I'm in a bit of a trouble with buttons, i have a task to make an inbox and to add a "reply" and "delete" button into every instance of the message. I was indeed wandering if there is a better way to do that than forcing the HTML code into the script, because every message is dynamically generated. Any help and/or suggestions would be very appreciated!(The objects are called from a JSON file). $(document).ready(function(){ $.getJSON('public/js/data.json', function(json){ $.each(json.data, function(i, data){ var output = ''; if(data.from.id != '234' && data.from.name != 'Alan Ford'){ $("#inbox").append( output += '<div class="post">'+ '<div class="h1">'+data.from.name+' - '+data.subject+'</div>'+ //this gives the name of the person who sent the message and the subject '<div class="content">'+data.message_formatted+'</div>'+ //The content of the message //buttons should be squeezed left of the date //this gives the date of the message sent '<div class="time">'+data.date_sent_formatted.formatted+'</div>'+ '</div>' ); }}); }); }); var date_sent=convertToDateTime(); function delete_message(id){ console.log('Delete message with id: '+id); } function reply_message(id, sender){ console.log('Message id: '+id); console.log('Reply to: '+sender); } The complete code in the JSFiddle . Just copy/pasted!

• Why changing the images name on server results in calling the old ones?

  - by moderns

  I am running a slideshow on Ubuntu 12.04.1 that loads the images (slide1.jpg, slide2.jpg, slide3.jpg.., slide5.jpg) using the Javascript and styles as below: document.getElementById('slide_area').className='slide'+step; .slide1{background-image: url(../upload/slide1.jpg)} .slide2{background-image: url(../upload/slide2.jpg)} .slide3{background-image: url(../upload/slide3.jpg)} .slide4{background-image: url(../upload/slide4.jpg)} .slide5{background-image: url(../upload/slide5.jpg)} When I change the images names (show1.jpg, show2.jpg, show3.jpg.., show5.jpg) and also change the style as below: .slide1{background-image: url(../upload/show1.jpg)} .slide2{background-image: url(../upload/show2.jpg)} .slide3{background-image: url(../upload/show3.jpg)} .slide4{background-image: url(../upload/show4.jpg)} .slide5{background-image: url(../upload/show5.jpg)} And open the network section on Chrome, I see the server is calling the new name and old name for images! I added the header in the index.php: header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0"); header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past header("Cache-Control: post-check=0, pre-check=0", false); header("Pragma: no-cache"); Nothing worked out with me and the slideshow doesn't work properly when I change the name of images even when clearing the browser cache as I load images sequentially (one by one) depending on imageObject.complete property! But without changing the name everything is going perfect and the images are loaded smoothly! Thank you for your help!

• Processing data from an AJAX request

  - by Josh K

  I have a PHP API I'm working with that outputs everything as JSON. I need to call one of the API methods and parse it out using an AJAX request. I am using jQuery (though it shouldn't matter). When I make the request it errors out with a "parsererror" as the textStatus and a "Syntax Error: invalid label" when I make the request. Simplified code: $.ajax ({ type: "POST", url: "http://mydomain.com/api/get/userlist/"+mid, dataType: "json", dataFilter: function(data, type) { /* Here we assume and pray */ users = eval(data); alert(users[1].id); }, success: function(data, textStatus, XMLHttpRequest) { alert(data.length); // Should be an array, yet is undefined. }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert(textStatus); alert(errorThrown); }, complete: function(XMLHttpRequest, textStatus) { alert("Done"); } }); If I leave off the eval(data) then everything works fine. Well, except for data still being undefined in success. Note that I'm taking an array of objects in PHP and then passing them out through json_encode. Would that make any difference? There has been no progress made on this. I'm willing to throw more code up if someone believes they can help. Here is the PHP side of things private function _get_user_colors($id) { $u = new User(); $u->get_where(array('id' => $id)); $bar = array(); $bar['user'] = $u->stored; foreach($user->colors as $color) { $bar['colors'][] = $color; } echo(json_encode($bar)); } I have had zero issues using this with other PHP based scripts. I don't know why Javascript would take issue with it.

• Need help with transferring data between MySQL db's using PHP

  - by JM4

  In one of the sites I manage, the client has decided to take on ACH/Bank Account administration where it was previously outsourced. As a result, the information submitted in our online form which used to simply store in a single database for processing now must sit in 'limbo' until the funds used for payment have been verified. My original plan is as follows: At the end of an enrollment, all form data is collected and stored in a single MySQL database. Our internal administrator will receive an email notification reminding him enrollments have taken place. He will process the ACH information collected and wait the 3-4 business days needed for payment to clear. Once the payment information has been returned as Good (haven't considered what I will do with the 'bad' yet), the administrator can log into a secure portal which allows him to click a button to 'process' the full information once compared and verified. the process is simplified as: Enrollment complete: data stored in DB 'A' Funds verified and link clicked: data from 'A' is copied to DB 'B' and 'A' is deleted. I have run similar processes with CSV output before and simply used //transfers old data to archive $transfer = mysql_query('INSERT INTO '.$archive.' SELECT * FROM '.$table) or die(mysql_error()); //empties existing table $query = mysql_query('TRUNCATE TABLE '.$table) or die(mysql_error()); but in those cases, ALL data returned was copied and deleted. I only want to copy and delete a single record. Any idea how to accomplish this?

• Web scrapping from a Google Chrome extension

  - by limoragni

  I've started to develop a Chrome extension to navigate and prform actions on a website. Until now the extension is able to receive a couple of parameters and check a set of radio-buttons, fill in a few inputs of a form and then submit it. What I want to do now is to repeat the process, but I'm stuck when the page is reloaded. And I don't know how can I do to make the script reacts to the finish of the request. The workflow I want to achieve is the following (is for automaticly copying a certain object): Popup side Enter the number of the Master object to copy Enter the base name of the copies (example Mod, so the I can iterate and add mod1, mod2, modn) Enter the number of copies Background side Select master Select standard options Fill in inputs Submit form Wait for the page to complete the request and continue to the next copy. (here I need help) The problem is on the repetition, the rest is taking care of. I assume that must be a way of dealing with requests. Any ideas? By the way I'm doing it all with the extension and tabs methods of google chrome plus javascript and jquery.

• Should I be worried if I don't get any internships by 3rd year's end?

  - by karamba

  I am in some mediocre college in some corner of India. Am about to complete 3rd year C.S. in a month and a half. I have no idea how to go about "finding an internship" as everyone seems to put it. Looking at online advice, I find that a primary way is to "use your contacts". I am sad to say that I don't have many friends(those I have, I am trying to get help from them for all it's worth), and my family can't help me as they have no idea about the software industry. My college has no official facility for aiding students in this, and the few faculty members who had contacts in "whatever" part of the industry have favoured some students that they have personally come to know. (Though I hear that the "internships" they got involve them stocking equipment in some small companies.... still it's something?) I'm getting nervous. I am considering just spending the coming summer refining my skills in C++ and begin learning MySQL and C#, both of which I have zero experience in. Maybe work on my own project... like a library management system. Relative to those in my college, I think I am among the best programmers there, but that isn't saying much as a lot of students can barely write basic code. I have experience in teaching myself C++, and DirectX9 having created a Tetris clone, some basic 3D apps (bouncing balls), and a basic console-based, text-file-database-using library management system (which I plan to improve this summer). Is it alright if I spend my summer so? Will I be able to get a job later on? I know I have to improve my social skills to get anywhere in life, and I will try, but say I am stuck like this till 4th year's end... will such self studying, online learning help me in landing a decent job? Perhaps after I have learned a bit more, joining some open source project?

• How would you structure your workflow for a web application ?

  - by cx42net

  Hi ! When designing a web application (or something else), it's good to have a workflow, and it's better to have a well ordered one. Starting with this idea in mind, I'd like to know what is your process from having an idea to maintain this great working project. For me actually, the process is the following one : Having the idea Checking this project already exists, and how it works Describing on a paper its functionalities finding a good and adequate name for this (and checking the domain availability with WHOISMyProject) Making a quick layout of the project on a paper Designing the project (via TheGimp, Photoshop, etc) Making a complete mockup of each pages Developing a prototype of the client-side application (with false datas) Developing the server side Testing Making the documentation/help/faq Releasing the project Maintaining it. Would you change the order of some points ? add/remove some ? I would please to know how you do that. I'm looking to set up a perfect workflow in order to make my project become real in the best way possible. Thank you for your opinion !

• Hide div based on url

  - by Ghetto Styles

  Sorry if this is another repost. I have been attempting to find a solution but nothing works that I have tried. I am using a blog which I have full html control over. I can usually find my way around basic html but when it comes to Java or CSS I am a complete newb. Sorry, I know absolutely nothing. Now that that is out of the way. I have two sidebar div's that I am trying to hide on one specific url to utilize more space for a content iframe. This is one of the coded I have tried to use which doesn't seem to work or I am missing something. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <script language="text/javascript" <?php &#36;(function(){ if (window.location.search === "mywebsite/Videos.html") { &#36;('#navleft').hide(); } else { &#36;('#navleft').show(); } }); ?> </script> Please remember I do not know anything when it comes to php or java. I want to do this for both #navright and #navleft. Also this is in the CSS section. Thanks for any help!! #navright{ width: 200px; } #navleft{ width: 200px; } #content{ margin:0px; }

• Optimize Duplicate Detection

  - by Dave Jarvis

  Background This is an optimization problem. Oracle Forms XML files have elements such as: <Trigger TriggerName="name" TriggerText="SELECT * FROM DUAL" ... /> Where the TriggerText is arbitrary SQL code. Each SQL statement has been extracted into uniquely named files such as: sql/module=DIAL_ACCESS+trigger=KEY-LISTVAL+filename=d_access.fmb.sql sql/module=REP_PAT_SEEN+trigger=KEY-LISTVAL+filename=rep_pat_seen.fmb.sql I wrote a script to generate a list of exact duplicates using a brute force approach. Problem There are 37,497 files to compare against each other; it takes 8 minutes to compare one file against all the others. Logically, if A = B and A = C, then there is no need to check if B = C. So the problem is: how do you eliminate the redundant comparisons? The script will complete in approximately 208 days. Script Source Code The comparison script is as follows: #!/bin/bash echo Loading directory ... for i in $(find sql/ -type f -name \*.sql); do echo Comparing $i ... for j in $(find sql/ -type f -name \*.sql); do if [ "$i" = "$j" ]; then continue; fi # Case insensitive compare, ignore spaces diff -IEbwBaq $i $j > /dev/null # 0 = no difference (i.e., duplicate code) if [ $? = 0 ]; then echo $i :: $j >> clones.txt fi done done Question How would you optimize the script so that checking for cloned code is a few orders of magnitude faster? System Constraints Using a quad-core CPU with an SSD; trying to avoid using cloud services if possible. The system is a Windows-based machine with Cygwin installed -- algorithms or solutions in other languages are welcome. Thank you!

• jQuery menu animation

  - by bomortensen

  Hi Stackoverflow, I'm building a website where I'm using jQuery to animate a horizontal tabbed menu. What I want to achieve can be seen here: / link removed / If you hover/mouseover the "Link 1" tab, you'll see that a white div is expanding. Each of the tab menu items are a styled li-tag. What I want to do is, that when you hover/mouseover i.e. the "Link 2" tab, the white div contracts and then expands again with content related to "Link 2" instead of "Link 1". Also, the "Link 1" tab should be expanded by default (i.e. when you just entered the site) Does any of you jQuery ninjas out there know how to do this? What I currently have is this: <script type="text/javascript"> $(document).ready(function(){ var $div = $('#divtest'); var height = $div.height(); $div.hide().css({ height : 0 }); $('#forside').hover(function () { if ($div.is(':visible')) { $div.animate({ height: 0 }, { duration: 200, complete: function () { $div.hide(); } }); } else { $div.show().animate({ height : height }, { duration: 200 }); } return false; }); }); </script> Do I need to have 4 different div's which expands/contracts for every mouseover? If i'm not being clear about what my problem is, please say so and I'll try to elaborate :) Thanks in advance!

• UPDATE Table SET Field

  - by davlyo

  This is my Very first Post! Bear with me. I have an Update Statement that I am trying to understand how SQL Server handles it. UPDATE a SET a.vField3 = b.vField3 FROM tableName a INNER JOIN tableName b ON a.vField1 = b.vField1 AND b.nField2 = a.nField2 – 1 This is my query in its simplest form. vField1 is a Varchar nField2 is an int (autonumber) vField3 is a Varchar I have left the WHERE clause out so understand there is logic that otherwise makes this a nessessity. Say vField1 is a Customer Number and that Customer has 3 records The value in nField2 is 1, 2, and 3 consecutively. vField3 is a Status When the Update comes to a.nField2 = 1 there is no a.nField2 -1 so it continues When the Update comes to a.nField2 = 2, b.nField2 = 1 When the Update comes to a.nField2 = 3, b.nField2 = 2 So when the Update is on a.nField2 = 2, alias b reflects what is on the line prior (b.nField2 = 1) And it SETs the Varchar Value of a.vField3 = b.vField3 When the Update is on a.nField2 = 3, alias b reflects what is on the line prior (b.nField2 = 2) And it (should) SET the Varchar Value of a.vField3 = b.vField3 When the process is complete –the Second of three records looks as expected –hence the value in vField3 of the second record reflects the value in vField3 from the First record However, vField3 of the Third record does not reflect the value in vField3 from the Second record. I think this demonstrates that SQL Server may be producing a transaction of some sort and then an update. Question: How can I get the DB to Update after each transaction so I can reference the values generated by each transaction?

• How to add an object to a html string?

  - by Philippe Maes

  I'm trying to load several images by a drop action and than resizing them and adding them as a thumbnail. The resize part is very important because the images can be very large and I want to make the thumbnails small of size. Here is my code: loadingGif(drop); for (var i=0;i<files.length;i++) { var file = files[i]; var reader = new FileReader(); reader.onload = function(e) { var src = e.target.result; var img = document.createElement('img'); img.src = src; var scale = 100/img.height; img.height = 100; img.width = scale*img.width; output.push('<div id="imagecontainer"><div id="image">'+img+'</div><div id="delimage"><img src="img/del.jpg"" /></div></div>'); if(output.length == files.length) { drop.removeChild(drop.lastChild); drop.innerHTML += output.join(''); output.length = 0; } } reader.readAsDataURL(file); } As you can probably tell I insert a loading gif image in my dropzone until all files are loaded (output.length == files.length). When a file is loaded I add html to an array which I will print if the load is complete. The problem is I can't seem to add the img object (I need this object to resize the image) to the html string, which seems obvious as the img is an object... So my question to you guys is: how do I do this? :)

• auto_complete plugin error: Couldn't find Question with ID=auto_complete_for_...

  - by bgadoci

  I have successfully set up this plugin before so I am curious as to what I am doing wrong here. I have built the ability for users to add tags to questions. I am not using tagging plugin here but that shouldn't matter for this. With respect to the auto complete, I am trying to have the form located in the /views/questions/show.html.erb file access the Tags table and display entries in the tags.tags_name column. When I begin to type in the field I get the following error message: Processing QuestionsController#show (for 127.0.0.1 at 2010-05-31 15:22:20) [GET] Parameters: {"tag"=>{"tag_name"=>"a"}, "id"=>"auto_complete_for_tag_tag_name"} Question Load (0.1ms) SELECT * FROM "questions" WHERE ("questions"."id" = 0) ActiveRecord::RecordNotFound (Couldn't find Question with ID=auto_complete_for_tag_tag_name): app/controllers/application_controller.rb:15:in `init_data' For some reason I am actually passing the field name as the Question.id. The plugin set up is fairly simple as you add the following line to your controller: auto_complete_for :tag, :tag_name and the following line in your routes.rb file: map.resources :tags, :collection => {:auto_complete_for_tag_tag_name => :get } I have added the controller line to both my tags and questions controller and also mapped resources for both tags and questions in my routes.rb file: map.resources :tags, :collection => {:auto_complete_for_tag_tag_name => :get } map.resources :questions, :collection => {:auto_complete_for_tag_tag_name => :get } I have played around with removing either or of the above but can't seem to fix it. Any ideas what I am doing wrong here? UPDATE: My QuestionsController#show action is fishing posts by: @question = Question.find(params[:id])

• VB looping complication

  - by user1819469

  I have to come up with a program that shifts names in a text box a random amount of times. I have gotten everything up to the point where the names shifts a random amount of times. It only shifts its once, but my messagebox appears through the code as many times as the names should be shifting once i click ok. Does anyone know why the loop is not working for the name shifts. I was thinking maybe the messagebox needs to control the loop, but I have searched endlessly and cannot find how that would be done. Any suggestions or referrals to other sites would be nice thanks. My code is below. Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim RandomNumber As Integer Dim min, max As Integer Dim temp, temp2, temp3, temp4, temp5, temp6 As String Dim i As Integer min = 3 max = 11 Randomize() RandomNumber = Int((max - min + 1) * Rnd() + min) temp = n1.Text temp2 = n2.Text temp3 = n3.Text temp4 = n4.Text temp5 = n5.Text temp6 = n6.Text For i = 0 To RandomNumber - 1 n1.Text = temp6 n2.Text = temp n3.Text = temp2 n4.Text = temp3 n5.Text = temp4 n6.Text = temp5 MessageBox.Show("Shift " & i & " of " & RandomNumber & " complete") Next End Sub End Class

• How can I synchronize one set of data with another?

  - by RenderIn

  I have an old database and a new database. The old records were converted to the new database recently. All our old applications continue to point to the old database, but the new applications point to the new database. Currently the old database is the only one being updated, so throughout the day the new database becomes out of sync. It is acceptable for the new database to be out of sync for a day, so until all our applications are pointed to the new database I just need to write a nightly cron job that will bring it up to date. I do not want to purge the new database and run the complete conversion script each night, as that would reduce uptime and would create a mess in our auditing of that table. I'm thinking about selecting all the data from the old database, converting it to the new database structure in memory, and then checking for the existence of each record before inserting it in the new database. After that's done, I'd select everything from the new database and check if it exists in the old one, and if not delete it. Is this the simplest way to do this?

• How important is it that models be consistent across project components?

  - by RonLugge

  I have a project with two components, a server-side component and a client-side component. For various reasons, the client-side device doesn't carry a fully copy of the database around. How important is it that my models have a 1:1 correlation between the two sides? And, to extend the question to my bigger concern, are there any time-bombs I'm going to run into down the line if they don't? I'm not talking about having different information on each side, but rather the way the information is encapsulated will vary. (Obviously, storage mechanisms will also vary) The server side will store each user, each review, each 'item' with seperate tables, and create links between them to gather data as necessary. The client side shouldn't have a complete user database, however, so rather than link against the user for gathering things like 'name', I'd store that on the review. In other words... --- Server Side --- Item: +id //Store stuff about the item User: +id +Name -Password Review: +id +itemId +rating +text +userId --- Device Side --- Item: +id +AverageRating Review: +id +rating +text +userId +name User: +id +Name //Stuff The basic idea is that certain 'critical' information gets moved one level 'up'. A user gets the list of 'items' relevant to their query, with certain review-orientation moved up (i. e. average rating). If they want more info, they query the detail view for the item, and the actual reviews get queried and added to the dataset (and displayed). If they query the actual review, the review gets queried and they pick up some additional user info along the way (maybe; I'm not sure if the user would have any use for any of the additional user information). My basic concern is that I don't wan't to glut the user's bandwidth or local storage with a huge variety of information that they just don't need, even if proper database normalizations suggests that information REALLY should be stored at a 'lower' level. I've phrased this as a fairly low-level conceptual issue because that's the level I'm trying to think / worry over, but if it matters I'm creating a PHP / MySQL server that provides data for a iOS / CoreData client.

• Is there a point to have multiple VS projects for an ASP.NET MVC application?

  - by mare

  I'm developing MVC application where I currently have 3 projects in solution. Core (it is supposed to be for Repositories, Business Classes, Models, HttpModules, HttpFilters, Settings, etc.) Data access (Data provider, for instance SqlDataProvider for working with SQL Server datastore - implements Repository interfaces, XmlDataProvider - also implements Repository interfaces but for local XML files as datastore) ASP.NET MVC project (all the typical stuff, UI, controllers, content, scripts, resources and helpers). I have no Models in my ASP.NET MVC project. I've just run into a problem because of that coz I want to use the new DataAnnotation feature in MVC 2 on my Bussiness class, which are, as said in Core, however I have I want to be able to localize the error messages. This where my problem starts. I cannot use my Resources from MVC project in Core. The MVC project references Core and it cannot be vice-versa. My options as I see them are: 1) Move Resources out but this would require correcting a whole bunch of Views and Controllers where I reference them, 2) Make a complete restructure of my app What are your thoughts on this? Also, Should I just move everything business related into Models folder in MVC project?? Does it even make any sense to have it structured like that, because we can just make subfolders for everything under MVC project? The whole Core library is not intended to ever be used for anything else, so there actually no point of compiling it to a separate DLL. Suggestions appreciated.

• Guidance on E-commerce in a Python Framework

  - by Ant

  I am looking for guidance in making decisions on using Python for E-commerce. My reasoning to use Python in the first place is i do a lot of 3D so it's a real help to use Python for web server side as well as 3D so I do not need to learn a new language. When I say E-commerce i mean the logic behind displaying products and a check out system that is Robust....and yes I really want to build this myself so I can change it. I do not want to use an out the box solution that costs a lot of money every month. I want control of server side, data bases, e-commerce etc. My questions are: What Frameworks are out there? I looked at previous questions on stackoverflow but only found old posts about Sachmo and Get paid. What is the learning path, I do not want to make a mistake that costs six months of studying? Python then Django? How long if I spent 10 hours a day studying this would it take to get up and running? I write javaScript badly, so I am not a complete noob, I understand the basics of programming languages. many thanks in advance

• .net remoting - Better solution to wait for a service to initialize ?

  - by CitizenInsane

  Context I have a client application (which i cannot modify, i.e. i only have the binary) that needs to run from time to time external commands that depends on a resource which is very long to initialize (about 20s). I thus decided to initialize this resource once for all in a "CommandServer.exe" application (single instance in the system tray) and let my client application call an intermediate "ExecuteCommand.exe" program that uses .net remoting to perform the operation on the server. The "ExecuteCommand.exe" is in charge for starting the server on first call and then leave it alive to speed up further commands. The service: public interface IMyService { void ExecuteCommand(string[] args); } The "CommandServer.exe" (using WindowsFormsApplicationBase for single instance management + user friendly splash screen during resource initializations): private void onStartupFirstInstance(object sender, StartupEventArgs e) { // Register communication channel channel = new TcpServerChannel("CommandServerChannel", 8234); ChannelServices.RegisterChannel(channel, false); // Register service var resource = veryLongToInitialize(); service = new MyServiceImpl(resource); RemotingServices.Marshal(service, "CommandServer"); // Create icon in system tray notifyIcon = new NotifyIcon(); ... } The intermediate "ExecuteCommand.exe": static void Main(string[] args) { startCommandServerIfRequired(); var channel = new TcpClientChannel(); ChannelServices.RegisterChannel(channel, false); var service = (IMyService)Activator.GetObject(typeof(IMyService), "tcp://localhost:8234/CommandServer"); service.RunCommand(args); } Problem As the server is very long to start (about 20s to initialize the required resources), the "ExecuteCommand.exe" fails on service.RunCommand(args) line because the server is yet not available. Question Is there a elegant way I can tune the delay before to receive "service not available" when calling service.RunCommand ? NB1: Currently I'm working around the issue by adding a mutex in server to indicate for complete initiliazation and have "ExecuteCommand.exe" to wait for this mutex before to call service.RunCommand. NB2: I have no background with .net remoting, nor WCF which is recommended replacer. (I chose .net remoting because this looked easier to set-up for this single shot issue in running external commands).

• jquery .animate - image gets cropped during animation

  - by stef

  Hello all, I am currently programming a carousel with javascript using the jquery library. Basically, there are three images shown, the central image being bigger than the two others. Upon going left or right, the central images is resized from 115px*115px to 50px*50px and tossed left or right, depending on the user input. The problem is that when the resize happens, the central image gets gradually cropped until it reaches the 50px*50px and then return to a more normal state: http://www.filedropper.com/imggetscropped Javascript is as follow: $("div#carousel .item:eq(2)").animate({'width':'50px', 'height':'50px', 'opacity':'0.5'}, {queue:false, duration:900}); $("div#carousel .item:eq(2) img").animate({'width':'50px', 'height':'50px', 'marginTop': '30px'}, {queue:false, duration:900}); $("div#carousel .item:eq(1)").animate({'width':'115px', 'height':'115px', 'opacity':'1'}, {queue:false, duration:900}); $("div#carousel .item:eq(1) img").animate({'width':'115px', 'height':'115px', 'marginTop': '0px'}, {queue:false, duration:900}); $("div#carousel .item:not(eq(2))").animate({'left':'+=56px'}, {queue:false, duration:900}); $("div#carousel .item:eq(2)").animate({'left':'+=122px'}, {queue:false, duration:900, complete: carousel.toggleInput}); Images used are png with transparency.

• AJAX Uploading - Not waiting for response before continuing

  - by waxical

  I'm using Blueimp's jQuery Uploader (very good it is too btw) and an S3 handler to upload files and then transfer them to S3 via the S3 API (from the PHP SDK). It works. The problem is, on large files (1GB) it can take anything up to a a few minutes to transfer (via create-object) onto S3. The PHP file that does this is hung-up until this process is complete. The problem is, the uploader (which utilises the jQuery Ajax method) seems to give up waiting and start again everytime. I have thought this was related to PHP INI 'max_input_time' or such, as it seemed to wait around 60 seconds, though this now appears to vary. I have upped the max_input_time in PHP INI and others related - but no further. I've also considered (the more likely) that JS, either in the script or the jQuery method has a timeout. The developer (blueimp) has said there's no such timeout in the front-end script, nor have I seen any and though 'timeout' is referenced in the jQuery Ajax method options, it seems to affect the entire time it uploads rather than the wait for a response - so that's not much use. Any help or guidance gratefully received.

• Configuring WPA WiFi in Ubuntu 10.10

  - by sma

  Hello, I am trying to configure my wireless network on my laptop running Ubuntu 10.10 and am having a bit of difficulty. I am a complete Linux newb, but want to learn it, hence the reason I'm trying to set this up. Here's the vitals: It is a Gateway 600 YG2 laptop. It was previously running Windows XP, but I installed Ubuntu 10.10 in place of it (not a dual boot, I removed XP altogether). I have an old wireless card that I'm trying to resurrect. I haven't really used the card in a couple years, but it seems to still work, I just can't connect to my home's wireless network. The card is a Linksys WPC11 v2.5. When I plug it in, Ubuntu recognizes the network, but won't connect to it. My home network uses WPA encryption and the only connection type that Ubuntu's network manager is giving me is WEP and then it asks for a key -- I have no idea what that key should be. So, basically, I'm asking, is there a way I can instead connect through WPA? I've tried creating a new connection in network manager, but that won't work, it keeps falling back to the WEP connection and asking me for a key. I have tried to install the XP driver using ndiswrapper but I don't know if that's working or not. Is there a way to tell if: A) the card is working as it should B) the correct drivers are installed (again, I installed the XP one using ndiswrapper NET8180.INF, but I'm not sure what to do next) Any help would be appreciated. Thank you.
