• A question of long-running and disruptive branches

  - by Matt Enright

  We are about to begin prototyping a new application that will share some existing infrastructure assemblies with an existing application, and also involve a significant subset of the existing domain model. Parts of the domain model will likely undergo some serious changes for this new application, and the endgame for all of this, once the new application has been fully specified and is launch-ready is that we would like to re-unify the models of the two applications (as well as share a database, link functionality, etc.), but for the duration of development, prototyping, etc, we will be using a separate database so that we can change things without worrying about impact to development or use of the existing application. Since it is a prototype, there will be a pretty long window during which serious changes or rearchitecturing can occur as product management experiments with different workflows, different customer bases are surveyed, and we try and keep up. We have already made a Subversion branch, so as to not impact concurrent development on the mature application, and are toying with 2 potential ways of moving forward with this: Use the svn branch as the sole mechanism of separation. Make our changes to the existing domain models, and evaluate their impact on the existing application (and make requisite changes to ProjectA) when we have established that our long-running side branch is stable enough for re-entry to trunk. "Fork" the shared code (temporarily): Copy ProjectA.Entities to NewProject.Entities, and treat all of the NewProject code as self-contained. When all of the perturbations around the model have died down and we feel satisfied, manually re-integrate the changes (as granular or sweeping as warranted) back into ProjectA.Entities, updating ProjectA to use the improved models at each step (this can take place either before or after the subversion merge has occurred). The subversion merge will then not handle recombination of any of the heavy changes here. Note: the "fork" method only applies to the code we see significant changes in store for, and whose modification will break ProjectA - shared infrastructure stuff for example, we would just modify in place (on our branch) and let the merge sort out. Development is hard, go shopping. Naturally, after not coming to an agreement, we're turning it over to the oracle of power that is SO. Any experience with any of these methods, pain points to watch out for, something new entirely?

• gwt get array button value

  - by graybow

  My gwt project have flexTable show data of image and button on each row and coll. But my button won't work properly. this is my current code: private Button[] b = new Button[]{new Button("a"),...,new Button("j")}; private int z=0; ... public void UpdateTabelGallery(JsArray str){ for(int i=0; i str.length(); i++){ b[i].setText(str.gettitle()); UpdateTabelGallery(str.get(i)); } } public void UpdateTabelGallery(GalleryData str){ Image img = new Image(); img.setUrl(str.getthumburl()); HTML himage= new HTML("a href="+str.geturl()+""+ img +"/a" + b[z] ); TabelGaleri.setWidget(y, x, himage); //is here th right place? b[z].addClickHandler(new ClickHandler(){ @Override public void onClick(ClickEvent event) { Window.alert("I wan to show the clicked button text" + b[z].getText()); } }); z++; } I'm still confuse where I should put my button handler. With this current code seems the clickhandler didn't work inside a looping. And if I put it outside loop its not working because I need to know which button clicked. I need to get my index button.but how? Is there any option than array button? thanks

• Send string from java (or other platform) to application

  - by MrSnowflake

  I want to send a barcode, read with my cellphone, to my computer. My computer has a simple server running, which listens to barcodes. When a barcode arrives, the server app should be able to input the value of the received barcode into the active application (I don't really care which application is going to get the input, the user should be able to select gedit, a terminal window or the browser if they choose to). My language at the moment is Java on GNU/Linux (Ubuntu), so I know about the Robot class. But the Robot class emulates a keyboard, which means: when you send VK_1 on a US keyboard layout, the output is '1' indeed, but when you send VK_1 on another layout (like belgian, which I use), which requires shift for the '1' key, the output is '&' (this is the character on the '1' key, when you don't hold shift). I also found xsendkeys, but this application too requires you to specify whether you need to hold shift. So it will be able to send an 'a' but for an 'A' (thus capital) you need to specify you want to hold shift with your 'a'. Isn't there an easy way to do this, for GNU/Linux and Windows, just using strings. I want to be able to send "12a68dd" to the active application. And I also would like to be able to send UTF-8 characters to the active application. I have been looking for a solution, but most require the breakdown in multiple keystrokes, which are often dependent on the keyboard layout.

• Trigger alert when database entries are added, not when they are removed

  - by Jeremy

  I have a jQuery script running that makes a periodic AJAX call using the following code. var a = moment(); var dayOfMonth = a.format("MMM Do"); var timeSubmitted = a.format("h:mm a"); var count_cases = -1; var count_claimed = -1; setInterval(function(){ //check if new lead was added to the db $.ajax({ type : "POST", url : "inc/new_lead_alerts_process.php", dataType: 'json', cache: false, success : function(response){ $.getJSON("inc/new_lead_alerts_process.php", function(data) { if (count_cases != -1 && count_cases != data.count) { window.location = "new_lead_alerts.php?id="+data.id; } count_cases = data.count; }); } }); This is the PHP that runs with each call: $count = mysql_fetch_array(mysql_query("SELECT count(*) as count FROM leads")); $client_id = mysql_fetch_array(mysql_query("SELECT id, client_id FROM leads ORDER BY id DESC LIMIT 1")); echo json_encode(array("count" => $count['count'], "id" => $client_id['id'], "client_id" => $client_id['client_id'])); I need to change the code so that the alert only triggers when a new entry is added to the database, not when an existing entry is removed. As it stands, the alert fires on both events. Any help is greatly appreciated.

• Can a Java HashMap's size() be out of sync with its actual entries' size ?

  - by trix

  I have a Java HashMap called statusCountMap. Calling size() results in 30. But if I count the entries manually, it's 31 This is in one of my TestNG unit tests. These results below are from Eclipse's Display window (type code - highlight - hit Display Result of Evaluating Selected Text). statusCountMap.size() (int) 30 statusCountMap.keySet().size() (int) 30 statusCountMap.values().size() (int) 30 statusCountMap (java.util.HashMap) {40534-INACTIVE=2, 40526-INACTIVE=1, 40528-INACTIVE=1, 40492-INACTIVE=3, 40492-TOTAL=4, 40513-TOTAL=6, 40532-DRAFT=4, 40524-TOTAL=7, 40526-DRAFT=2, 40528-ACTIVE=1, 40524-DRAFT=2, 40515-ACTIVE=1, 40513-DRAFT=4, 40534-DRAFT=1, 40514-TOTAL=3, 40529-DRAFT=4, 40515-TOTAL=3, 40492-ACTIVE=1, 40528-TOTAL=4, 40514-DRAFT=2, 40526-TOTAL=3, 40524-INACTIVE=2, 40515-DRAFT=2, 40514-ACTIVE=1, 40534-TOTAL=3, 40513-ACTIVE=2, 40528-DRAFT=2, 40532-TOTAL=4, 40524-ACTIVE=3, 40529-ACTIVE=1, 40529-TOTAL=5} statusCountMap.entrySet().size() (int) 30 What gives ? Anyone has experienced this ? I'm pretty sure statusCountMap is not being modified at this point. There are 2 methods (lets call them methodA and methodB) that modify statusCountMap concurrently, by repeatedly calling incrementCountInMap. private void incrementCountInMap(Map map, Long id, String qualifier) { String key = id + "-" + qualifier; if (map.get(key) == null) { map.put(key, 0); } synchronized (map) { map.put(key, map.get(key).intValue() + 1); } } methodD is where I'm getting the issue. methodD has a TestNG @dependsOnMethods = { "methodA", "methodB" } so when methodD is executing, statusCountMap is pretty much static already. I'm mentioning this because it might be a bug in TestNG. I'm using Sun JDK 1.6.0_24. TestNG is testng-5.9-jdk15.jar Hmmm ... after rereading my post, could it be because of concurrent execution of outside-of-synchronized-block map.get(key) == null & map.put(key,0) that's causing this issue ?

• Color banding only on Android 4.0+

  - by threeshinyapples

  On emulators running Android 4.0 or 4.0.3, I am seeing horrible colour banding which I can't seem to get rid of. On every other Android version I have tested, gradients look smooth. I have a SurfaceView which is configured as RGBX_8888, and the banding is not present in the rendered canvas. If I manually dither the image by overlaying a noise pattern at the end of rendering I can make the gradients smooth again, though obviously at a cost to performance which I'd rather avoid. So the banding is being introduced later. I can only assume that, on 4.0+, my SurfaceView is being quantized to a lower bit-depth at some point between it being drawn and being displayed, and I can see from a screen capture that gradients are stepping 8 values at a time in each channel, suggesting a quantization to 555 (not 565). I added the following to my Activity onCreate function, but it made no difference. getWindow().setFormat(PixelFormat.RGBA_8888); getWindow().addFlags(WindowManager.LayoutParams.FLAG_DITHER); I also tried putting the above in onAttachedToWindow() instead, but there was still no change. (I believe that RGBA_8888 is the default window format anyway for 2.2 and above, so it's little surprise that explicitly setting that format has no effect on 4.0+.) Which leaves the question, if the source is 8888 and the destination is 8888, what is introducing the quantization/banding and why does it only appear on 4.0+? Very puzzling. I wonder if anyone can shed some light?

• How to focus a control in an MDIParent when all child windows have closed?

  - by Tim Gradwell

  I have a control in my parent mdi form which I wish to be given the focus if all mdi children have closed. I've tried hooking into the child form's FormClosed event and setting the focus from there but when I test it, my control is not left with focus when I close the mdi child. Can anyone tell me what I'm missing? In the sample below, "first focus" gets hit and does its job correctly (if I comment out the first focus line, my tree does not get focus on startup, so it must be doing its job, right?) Unfortunately, even though "second focus" gets hit, my tree does not end up with the focus when I close the child window. Sample using System; using System.Windows.Forms; namespace mdiFocus { class ParentForm : Form { public ParentForm() { IsMdiContainer = true; tree = new TreeView(); tree.Nodes.Add("SomeNode"); tree.Dock = DockStyle.Left; Controls.Add(tree); } protected override void OnShown(EventArgs e) { Form child = new Form(); child.MdiParent = this; child.Show(); child.FormClosed += new FormClosedEventHandler(child_FormClosed); tree.Focus(); // first focus works ok } void child_FormClosed(object sender, FormClosedEventArgs e) { tree.Focus(); // second focus doesn't seem to work, even though it is hit :( } TreeView tree; } static class Program { [STAThread] static void Main() { Application.Run(new ParentForm()); } } }

• Sending variable data from one of two text boxes to javascript

  - by Enyalius

  Greetings, all! I am fairly new to JS (my background is in C++, enterprise languages like assembly and COBOL, and some light .NET), so I was wondering if I could get some advice regarding how to send variable information from one of two text boxes to some javascript and then have the JS do some basic checks and such. Here's the pseudocode for what I am trying to do: <form = webForm> <p> _____________ textboxPeople| searchIcon //a text box to search an online phonebook at my company. ------------- //It has a little "magnifying glass" icon to search //(onClick), but I would also like them to be able to //search by hitting the "enter" key on their keyboards. </p> <p> _____________ texboxIntranet| searchIcon //Same as above search textbox, but this one is used if ------------- //the user wishes to search my corporate intranet site. </form> So ends the front-facing basic form that I would like to use. Now, onClick or onEnter, I would like the form to pass the contents of the text box used as well as an identifier such as "People" or "Intranet," depending on which box is used, to some basic JS on the back end: begin JavaScript: if(identifier = 'People') fire peopleSearch(); else if(identifier = 'Intranet') fire intranetSearch(); function peopleSearch() { http://phonebook.corporate.com/query=submittedValue //This will take the person //that the user submitted in the form and //place it at the end of a URL, after which //it will open said complete URL in the //same window. } function intranetSearch() { http://intranet.corporate.com/query=submittedValue //This will function in the //same way as the people search function. } end JavaScript Any thoughts/suggestions would be greatly appreciated. Thank you all in advance!

• Python Webkit browser's inspector is missing a few things

  - by NoBugs

  I'm using a Webkit browser inspector like this. When I run it in Ubuntu 12.10, I'm getting errors when using the inspector. For example: ** Message: console message: file:///usr/share/webkitgtk-1.0/webinspector/UIString.js @42: Localized string "Go to line" not found. ** Message: console message: file:///usr/share/webkitgtk-1.0/webinspector/UIString.js @42: Localized string "Filter" not found. ** Message: console message: file:///usr/share/webkitgtk-1.0/webinspector/UIString.js @42: Localized string "Search Previous" not found. ** Message: console message: file:///usr/share/webkitgtk-1.0/webinspector/UIString.js @42: Localized string "Search Next" not found. ** Message: console message: file:///usr/share/webkitgtk-1.0/webinspector/UIString.js @42: Localized string "a:" not found. ** Message: console message: file:///usr/share/webkitgtk-1.0/webinspector/UIString.js @42: Localized string "%d of %d" not found.

I also noticed the breadcrumb/slider bar doesn't show when you have the console in the lower half: I don't remember this in earlier versions, and when I use the GTK3 version (from gi.repository import WebKit etc) it has similar problem, and is even worse, scrollbars don't have arrows at top and bottom. Am I missing a step on initializing the Webkit inspector or English locale for it? I would like to debug this issue, but since the inspector object isn't a webview object, I'm not sure I can add an inspector to the inspector? (like how you can use F12 when inspector is its own window in Chrome/Chromium, which lets you debug that inspector). It should be possible, but maybe not with pyGTK?

• Jquery Works in FF but not IE at all

  - by Shawn

  I set up the SimpleModal plugin to work from our Ad server(Real 24/7). Essentially, attempting to make an interstitial ad. I serve a popupAd.js file from the Ad Server to our homepage(index.php), Here is the code for popupAd.js: $(document).ready(function() { $.modal('<iframe src="/welcomeAd.htm" height="525" width="562" style="border:0;" scrolling="no"/>', { closeHTML: "<a href='#' title='Close' align='right' style='color:#666>(X) Continue to website</a>", containerCss: { backgroundColor: '#fff', borderColor: "#0063dc", height: 525, padding: 0, width: 562, }, overlayCss:{ backgroundColor:"#fff", }, opacity:100, overlayClose: true }); }); This opens a modal window on the homepage which then loads welcomeAd.htm which contain nothing other than the ad call to the creative. Here is the code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/1999/REC-html401-19991224/loose.dtd"> <html> <head> <title>Company Name</title> <!------ AD SERVER SETUP begin ------> <!------ OAS SERVER SETUP end ------> </head> <body style="margin: 0; padding: 0; width: 100%; height: 100%"> <script type="text/javascript" language="JavaScript"> <!-- AD SERVER CALL; //--> </script> </body> </html> This all works in FF but does nothing in IE, of which I am running IE7. Also, the closeHTML doesn't show up in Safari, though, the ad does.

• Automating Excel through the PIA makes VBA go squiffy.

  - by Jon Artus

  I have absolutely no idea how to start diagnosing this, and just wondered if anyone had any suggestions. I'm generating an Excel spreadsheet by calling some Macros from a C# application, and during the generation process it somehow breaks. I've got a VBA class containing all of my logging/error-handling logic, which I instantiate using a singleton-esque accessor, shown here: Private mcAppFramework As csys_ApplicationFramework Public Function AppFramework() As csys_ApplicationFramework If mcAppFramework Is Nothing Then Set mcAppFramework = New csys_ApplicationFramework Call mcAppFramework.bInitialise End If Set AppFramework = mcAppFramework End Function The above code works fine before I've generated the spreadsheet, but afterwards fails. The problem seems to be the following line; Set mcAppFramework = New csys_ApplicationFramework which I've never seen fail before. If I add a watch to the variable being assigned here, the type shows as csys_ApplicationFramework/wksFoo, where wksFoo is a random worksheet in the same workbook. What seems to be happening is that while the variable is of the right type, rather than filling that slot with a new instance of my framework class, it's making it point to an existing worksheet instead, the equivalent of Set mcAppFramework = wksFoo which is a compiler error, as one might expect. Even more bizarrely, if I put a breakpoint on the offending line, edit the line, and then resume execution, it works. For example, I delete the word 'New' move off the line, move back, re-type 'New' and resume execution. This somehow 'fixes' the workbook and it works happily ever after, with the type of the variable in my watch window showing as csys_ApplicationFramework/csys_ApplicationFramework as I'd expect. This implies that manipulating the workbook through the PIA is somehow breaking it temporarily. All I'm doing in the PIA is opening the workbook, calling several macros using Excel.Application.Run(), and saving it again. I can post a few more details if anyone thinks that it's relevant. I don't know how VBA creates objects behind the scenes or how to debug this. I also don't know how the way the code executes can change without the code itself changing. As previously mentioned, VBA has frankly gone a bit squiffy on me... Any thoughts?

• listener not being called

  - by deb

  I have a table with a button. When the button is clicked I call Modalbox.show (http://okonet.ru/projects/modalbox/) that displays a little form with another button. When the user clicks this second button, a listener is attached to an iframe in the form and the form is submitted to the server. The server does something then it should return back to the form and execute the listener function. This works fine on IE but not in Firefox (on Firefox it never comes back). Here it is the javascript function that is called when the user presses the second button (in the Modalbox) function attachFile() { //window.frames['upload_iframe'].name='upload_iframe'; iframe = document.getElementById('upload_iframe'); if (iframe.addEventListener)//FF iframe.addEventListener("load", iframeEventHandler, false); if (iframe.attachEvent)//IE iframe.attachEvent("onload", iframeEventHandler); // Set properties of form... form = document.getElementById('attchForm'); form.setAttribute("target","upload_iframe"); form.setAttribute("method","post"); form.setAttribute("enctype","multipart/form-data"); form.setAttribute("encoding","multipart/form-data"); // Submit the form... form.submit(); } I checked that it is adding the listener but somehow does not return to it. Any hints? Thanks deb

• Is it possible to reference remote content from chrome.manifest? (XULRunner)

  - by siemaa

  Hi, I have a xulrunner application and I've been trying to reference remote content from chrome.manifest file. Tt's an application for the company I work in; it's run on a number of computers (most of them are used by other employees as well) as a kind of an internet monitoring service. The problem I'd like to solve is this: updating the code of such application usually requires me to manually copy the modified files to every computer that the application is running on (I've had no luck trying to make automatic updates via xulrunner platform). This process has become very tedious. What I'd like to have is a web server, where all of the xul and js files would be accessible, so that every application could reference them from there. This would require me only to update the code on that server, and the applications (when restarted) would automatically get the latest code. What I managed to do: I can reference js scripts from a xul file using http based urls and everything works fine (I can use local, binary components etc.), although the xul file has to be local - that I'd like to change. But when I write in chrome.manifest a line like: content my_app http://path/to/app/files/ and then use the line in default/preferences/pref.js pref("toolkit.defaultChromeURI", "chrome://my_app/content/my_app.xul"); it just opens a console window (to test I manually run the application with the -console option) and no code gets executed. The file can be downloaded remotely using wget so I guess this isn't the web server issue. The applications work on Windows machines. Is there some kind of security issue causing such behavior or am I doing something wrong? Is it even possible to register remote, http based content as chrome?

• Changing PHP variable from an <a href=""> link

  - by aener

  I'm making a site using divs. I have one across the top with a row of links which I want to change what's in the main window. I would prefer to keep strictly to PHP and HTML and use a full page refresh as I am comfortable with them at current, rather than using an Ajax refresh as I don't have any knowledge of Ajax. I don't want to use iframes. I thought the best way to do this would be as follows: <div id="top"> <a href="news.html">News</a> </div> <div id="main"> <?php include($page); ?> </div> What I need is a way of changing the $page variable upon clicking the link. If this means changing the variable and then reloading the page then so be it. A command following the logic of: <a href="news.html" action="<?php $page="news.html"; ?>">News</a> would be ideal! I thought about using a form, but it seems there should be an easier way.

• Can't get Dialog hosting a WebView to layout properly

  - by user246114

  Hi, I'm trying to host a webview on a dialog, without a titlebar, but I'm getting odd layout results. Example test: @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); WindowManager wm = (WindowManager)getContext().getSystemService(Context.WINDOW_SERVICE); Display display = wm.getDefaultDisplay(); LinearLayout ll = new LinearLayout(getContext()); ll.setOrientation(LinearLayout.VERTICAL); ll.setLayoutParams(new LayoutParams( LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT)); ll.setMinimumWidth(display.getWidth() - 10); ll.setMinimumHeight(display.getHeight() - 10); WebView wv = new WebView(getContext()); wv.setLayoutParams(new LayoutParams( LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT)); wv.getSettings().setJavaScriptEnabled(true); ll.addView(mWebView); setContentView(ll, new LinearLayout.LayoutParams( LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT)); } the dialog is inflated at startup, but the webview is not visible. If I rotate the device, it becomes visible, and fills the whole parent layout as requested. What is the right way to do this? I simply want a dialog which occupies most of the device screen, and has a WebView on it which fills the entire space. Thanks

• "render as JSON" is display JSON as text instead of returning it to AJAX call as expected

  - by typoknig

  I'm navigating to the index action of MyController. Some of the on the index page I'm making an AJAX call back to myAction in MyController. I expect myAction action to return some data as JSON to my AJAX call so I can do something with the data client side, but instead of returning the data as JSON like I want, the data is being displayed as text. Example of my Grails controller: class MyController { def index() { render( view: "myView" ) } def myAction { def mapOfStuff = [ "foo": "foo", "bar":] render mapOfStuff as JSON } } Example of my JavaScript: $( function() { function callMyAction() { $.ajax({ dataType: 'json', url: base_url + '/myController/myAction', success: function( data ) { $(function() { if( data.foo ) { alert( data.foo ); } if( data.bar ) { alert( data.bar ); } }); } }); } }); What I expect is that my page will render, then my JavaScript will be called, then two alerts will display. Instead the JSON array is displayed as text in my browser window: {"foo":"foo","bar":"bar"} At this point the last segment of the URL in my address bar is myAction and not index. Now if I manually enter the URL of the index page and press refresh, all works as expected. I have half a dozen AJAX calls I do the exact same way and none of them are having problems. What is the deal here? UPDATE: I have noticed something. When I set a break point in the index action of MyController and another one in the myAction action, the break point in myAction gets hit BEFORE the break point in index, even though I am navigating to the index. This is obviously closer to the root cause of my problem, but why is it happening?

  I'm trying to send mouse clicks to a program. As I don't want the mouse to move, I don't want to use SendInput or mouse_event, and because the window that should receive the clicks doesn't really use Buttons or other GUI events, I can't send messages to these buttons. I'm trying to get this working using SendMessage, but for some reason it doesn't work. Relevant code is (in C#, but tried Java with jnative as well), trying this on Vista [DllImport("user32.dll", CharSet=CharSet.Auto)] public static extern int SendMessage(IntPtr A_0, int A_1, int A_2, int A_3); static int WM_CLOSE = 0x10; static int WM_LBUTTONDOWN = 0x201; static int WM_LBUTTONUP = 0x202; public static void click(IntPtr hWnd, int x, int y) { SendMessage(hWnd, WM_LBUTTONDOWN, 1, ((x << 0x10) ^ y)); SendMessage(hWnd, WM_LBUTTONUP, 0, ((x << 0x10) ^ y)); } public static void close(IntPtr hWnd) { SendMessage(hWnd, WM_CLOSE, 0, 0); } The close works fine, but the click doesn't do anything.

• Major JQuery bug on IE not reproducible - What can i do in this situation to solve this bug?

  - by ming yeow

  I am hoping to get some help on this issue. Some users on IE have been reporting this javascript issue, but I have been unable to re-produce it. In essence, for some class of windows IE users, the game doesn't work (or $.ajax() is not working). What I know: I swapped out an ajax call (ajax_init_trainer) and used a standard link with some request parameters to do the initialization and ppl seemed to get passed the problem until they hit the next ajax call. I read somewhere that IE does crazy caching so you need to make the urls unique, which is why i added the _requestno parameter. However, setting the cache:false is said to also do this. This didn't fix it for someone who was complaining. function done(res, status) { var data = JSON.parse(res.responseText); hide_loading(); if (status == "success") { window.location.href="/bamo/battle/?{{ fb_sig}}"; } else { display_alert("Problem!",data.msg,$("#notifications")); } }; $(".monster_select_class").click(function() { $(this).attr("src","{{MEDIA_URL}}/bamo/button_select_click.png"); monster_class = $(this).attr("monster_class"); monster_type = $(this).attr("monster_type"); ajax_init_trainer(monster_class,monster_type); }); function ajax_init_trainer(trainer_class,monster_type) { var data = {trainer_class:trainer_class,monster_type:monster_type}; var d = new Date(); var args = { type:"POST",url:"/bamo/api/init_trainer/?_requestno="+d.getTime(),data:data,contentType:"application/json;", dataType: "json",cache:false,complete:done}; $.ajax(args); return false; };

  - by Kero

  I need to check on disabling JavaScript if the user disabled JavaScript from browser or firewall or any other place he will never show the form. I have lots of search and solutions, but unfortunately didn't got the right one. - Using style with no-script tag: This one could be broke with removing style... <noscript> <style type="text/css"> .HideClass { display:none; } </style> </noscript> The past code will work just fine but there is lots of problems in no-script tag as here Beside that i don't want to redirect user with no-script tag too...Beside that i can quickly stop loading the page to broke this meta or disable Meta tag from IE: <meta http-equiv="refresh" content="0; URL=Frm_JavaScriptDisable.aspx" /> Another way to redirect user with JavaScript but this will work let's say for 99% of users and this one isn't lovely way and will slow down the website... window.location="http://www.location.com/page.aspx"; Is there is any other ideas or suggestions to secure working with JavaScript...and prevent user from entering the website or see my form except when JavaScript enabled...

  - by user356170

  i have a question. I have a website in which i am giving security like login id and password( as usual). No what i want is that, 1) I don't want to allow a single user to login in different machine at the same time. 2) For this i am using a column in database which is keeping the current status of user(i.e. loging/logout). I am allowing user to login only when has session has not closed and status is login. 3) So my problem is that when i am logging out manually. it is closing the session as well as updating the database with status "logout". 4) but when i am closing the window from Cross buttonat top right corner. it is closing the ssion but table data is still "login". so later on i can't be able to login into the same user. 5) So how could i solve this problem. Please help me!
