  • clicking on a button clientSide does not cause postback

    - by Andreas Niedermair
    see this example: <form runat="server"> <asp:Button runat="server" ID="btFoo" Text="asp.net button" /> <button id="btFoo2">open modal</button> <script type="text/javascript"> $(document).ready(function() { var btFoo = $('#<%= this.btFoo.ClientID %>'); btFoo.click(); // this will work and cause a postback btFoo.click(function() { alert('click triggered'); }); var dialog = $('<div/>'); dialog.text('please click yes'); dialog.dialog({ autoOpen: false, open: function() { var widget = dialog.dialog('widget'); widget.appendTo($('form')); }, buttons: { 'YES': function() { btFoo.click(); // this will cause a click, but no postback??!! } } }); var btFoo2 = $('#btFoo2'); btFoo2.click(function() { dialog.dialog('open'); return false; }); }); </script> </form> any help would be appreciated, to get this example working!

  • Compilig + testing an Android library with the JDK?

    - by Jarle Hansen
    Hi all, I am creating a library for Android that others can include in their own project. So far I have been working on it as a normal Java project with JDK 1.6 setup as system library. This works just fine in Eclipse when I add the android.jar. The issue comes when I try to my build script. I am running Gradle and doing a normal compile and test build cycle. My thoughts were that it does not matter if I compile it with a normal JDK, since this is not a standalone application. The benefits by creating a normal Java project is that Gradle does support this much better. My project also does not contain any UI at all. However, the problem is that of course android.jar and the JDK contains lots of the same classes and I think that this is what messes up my build script. Everything crashes when running the tests (the tests are in the same project under src/test/java). My question is, how should I create this project that is meant to be included in Android projects as a third party library? Should I create it as an Android project in Eclipse even though I am only creating a library that does not use any of the UI features? Also, should the tests be in a separate project? Thanks for all responses!

  • DBIx::Class base result class

    - by Rob
    Hi there, I am trying to create a model for Catalyst by using DBIx::Class::Schema::Loader. I want the result classes to have a base class I can add methods to. So MyTable.pm inherits from Base.pm which inherits from DBIx::Class::core (default). Somehow I cannot figure out how to do this. my create script is below, can anyone tell me what I am doing wrong? The script creates my model ok, but all resultset classes just directly inherit from DBIx::Class::core without my Base class in between. #!/usr/bin/perl use DBIx::Class::Schema::Loader qw/ make_schema_at /; #specifically for the entities many-2-many relation $ENV{DBIC_OVERWRITE_HELPER_METHODS_OK} = 1; make_schema_at( 'MyApp::Schema', { dump_directory => '/tmp', debug => 1, overwrite_modifications => 1, components => ['EncodedColumn'], #encoded password column use_namespaces => 1, default_resultset_class => 'Base' }, [ 'DBI:mysql:database=mydb;host=localhost;port=3306','rob', '******' ], );

  • Please help with IFrame callback

    - by Code Sherpa
    Hi - thanks for clicking. I am trying to get status feedback using an IFrame for file uploads. I am not trying to get progress or percentages - just when a file is done uploading and if it was a success or failure. THE PROBLEM is that I can't seem to get the server response to appear on the client. I have to following design: I have an iframe on my page: <iframe id="target_frame" src="" style="border:0px; width:0px; height:0px"></iframe> The form tag points to it: <form enctype="multipart/form-data" id="fileUploadForm" name="fileUploadForm" action="picupload.aspx" method="post" target="target_frame"> And the submit button starts a file upload via the iframe: <input id="submit" type="submit" value="upload" /> In the picupload.aspx.cs file, I have a method that returns dynamic data. I then send it to the client: message = data; Response.Write(String.Format("<script language='javascript' type='text/javascript'>window.parent.handleResponse('{0}');</script>", message)); On the client, I have a response handler: function handleResponse(msg) { document.getElementById('statusDiv').innerHTML = msg; } My intent is to see the msg value change for each uploaded file but I never see anything appear in statusDiv, let alone dynamically changing messages. Can somebody please help??

  • Calling a javascript function from an aspx.cs code behind

    - by David Hodgson
    Hi, I would like to call a javascript function from an aspx control. For instance, suppose I had: <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Untitled Page</title> <script type="text/javascript"> function test(x, y) { } </script> </head> <body> <form id="form1" runat="server"> <div> <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click"/> </div> </form> </body> </html> and in the code behind: protected void Button1_Click(object sender, EventArgs e) { // do stuff (really going to a database to fill x and y) int[] x = new int[] { 1, 2, 3, 4, 5 }; int[] y = new int[] { 1, 2, 3, 4, 5 }; // call javascript function as test(x,y); } Is there a way to do it?

  • Generate A Simple Read-Only DAL?

    - by David
    I've been looking around for a simple solution to this, trying my best to lean towards something like NHibernate, but so far everything I've found seems to be trying to solve a slightly different problem. Here's what I'm looking at in my current project: We have an IBM iSeries database as a primary repository for a third party software suite used for our core business (a financial institution). Part of what my team does is write applications that report on or key off of a lot of this data in some way. In the past, we've been manually creating ADO .NET connections (we're using .NET 3.5 and Visual Studio 2008, by the way) and manually writing queries, etc. Moving forward, I'd like to simplify the process of getting data from there for the development team. Rather than creating connections and queries and all that each time, I'd much rather a developer be able to simply do something like this: var something = (from t in TableName select t); And, ideally, they'd just get some IQueryable or IEnumerable of generated entities. This would be done inside a new domain core that I'm building where these entities would live and the applications would interface with it through a request/response service layer. A few things to note are: The entities that correspond to the database tables should be generated once and we'd prefer to manually keep them updated over time. That is, if columns/tables are added to the database then we shouldn't have to do anything. (If some are deleted, of course, it will break, but that's fine.) But if we need to use a new column, we should be able to just add it to the necessary class(es) without having to re-gen the whole thing. The whole thing should be SELECT-only. We're not doing a full DAL here because we don't want to be able to break anything in the database (even accidentally). We don't need any kind of mapping between our domain objects and the generated entity types. The domain barely covers a fraction of the data that's in there, most of it we'll never need, and we would rather just create re-usable maps manually over time. I already have a logical separation for the DAL where my "repository" classes return domain objects, I'm just looking for a better alternative to manual ADO to be used inside the repository classes. Any suggestions? It seems like what I'm doing is just enough outside the normal demand for DAL/ORM tools/tutorials online that I haven't been able to find anything. Or maybe I'm just overlooking something obvious?

  • XMLHttpRequest leak

    - by Raja
    Hi everyone, Below is my javascript code snippet. Its not running as expected, please help me with this. <script type="text/javascript"> function getCurrentLocation() { console.log("inside location"); navigator.geolocation.getCurrentPosition(function(position) { insert_coord(new google.maps.LatLng(position.coords.latitude,position.coords.longitude)); }); } function insert_coord(loc) { var request = new XMLHttpRequest(); request.open("POST","start.php",true); request.onreadystatechange = function() { callback(request); }; request.setRequestHeader("Content-Type","application/x-www-form-urlencoded"); request.send("lat=" + encodeURIComponent(loc.lat()) + "&lng=" + encodeURIComponent(loc.lng())); return request; } function callback(req) { console.log("inside callback"); if(req.readyState == 4) if(req.status == 200) { document.getElementById("scratch").innerHTML = "callback success"; //window.setTimeout("getCurrentLocation()",5000); setTimeout(getCurrentLocation,5000); } } getCurrentLocation(); //called on body load </script> What i'm trying to achieve is to send my current location to the php page every 5 seconds or so. i can see few of the coordinates in my database but after sometime it gets weird. Firebug show very weird logs like simultaneous POST's at irregular intervals. Here's the firebug screenshot: IS there a leak in the program. please help. EDIT: The expected outcome in the firebug console should be like this :- inside location POST .... inside callback /* 5 secs later */ inside location POST ... inside callback /* keep repeating */

  • How to write to a Text File in Pipe delimited format from MS Sql Server / ASP.Net?

    - by NJTechGuy
    I have a text file which needs to be constantly updated (regular intervals). All I want is the syntax and possibly some code that outputs data from a MS Sql Database using ASP.Net. The code I have so far is : <%@ Import Namespace="System.IO" %> <script language="vb" runat="server"> sub Page_Load(sender as Object, e as EventArgs) Dim FILENAME as String = Server.MapPath("Output.txt") Dim objStreamWriter as StreamWriter ' If Len(Dir$(FILENAME)) > 0 Then Kill(FILENAME) objStreamWriter = File.AppendText(FILENAME) objStreamWriter.WriteLine("A user viewed this demo at: " & DateTime.Now.ToString()) objStreamWriter.Close() Dim objStreamReader as StreamReader objStreamReader = File.OpenText(FILENAME) Dim contents as String = objStreamReader.ReadToEnd() lblNicerOutput.Text = contents.Replace(vbCrLf, "<br>") objStreamReader.Close() end sub </script> <asp:label runat="server" id="lblNicerOutput" Font-Name="Verdana" /> With PHP, it is a breeze, but with .Net I have no clue. If you could help me with the database connectivity and how to write the data in pipe delimited format to an Output.txt file, that had be awesome. Thanks guys!

  • Create dynamic view with android

    - by ekevin
    Hi I'm stuck on a problem and if possible I will need help from the community. I'm not looking for a ready-made solution, but something which would help me to produce the result. I'm looking for a way to produce a dynamic activity based on a JSON object. Here an example of a JSON object: [ { "name": "my checkbox name", "type": "checkbox", "value": "one,two,three" } { "name": "my edit text", "type": "text", "value": "" } ...] This JSONObject could be totally random. I could have 2 text views, 3 select menus, 1 text view and so on. The goal is to iterate over this JSONObject and create the appropriate elements within my android code. To produce the result I've thought of a simple switch which would render one by one my different JSONObject to an android widget. But after that how could I have access of every property of every widget rendered? Thank you.

  • How to detect circles accurately

    - by user1767798
    Is there any way to accurately detect circles in opencv? I was using hough transform which give me good result but most of the time, shadow of the object and surrounding,light etc gives bad results, so am looking for options other than hough circles, accurate detection is very important for my project. My basic approach so far is to find some spheres in the image taken in realtime. I am using houghcircle to find the spheres and base later calculations on the radius I am getting from that. If the background is plain and nothing the sphere detect without problem, however if I am taking that image in my room where the background will have other objects it's often difficult to detect. So am looking for some other approach.

  • jQuery: If, Else with buttons error

    - by Wipqozn
    I'm running into an odd error. I'm working in Django 1.2, and have implemented the commenting framework. I'm trying to attach a hide/show button to each comment field, but whenever click on a hide/show button, it behaves as if each hide/show button beneath it on the page was clicked. Here's the jQuery code: <input type="Button" id="hideShow" name="hide/show" value="Hide"></input> <script> $("#hideShow").click(function() { if($(this).val() == "Hide") { $("textarea").hide("fast"); $(this).val("Show"); } else { $("textarea").show("fast"); $(this).val( "Hide"); } }); </script> So, when I click the Hide/show button, it will perform the action for each button beneath the clicked button + once for the button itself. So If I click a button, and there are two buttons beneath it, and value=hide it will first hide the 'textarea', than show the text area, than finally hide it again. I'm new to jQuery (although I do have experience in other languages), and I have an -idea- why it's not working: that whenever an action is performed jQuery jumps to the first one, than continues down the page looking for any other actions performed, and responds to each one. So it comes to my first button, sets it as being clicked, and so when jQuery comes across the other buttons it views them all as being 'clicked' and performs actions accordingly. I've thought of a semi-solution to my problem, putting in a variable which tracks how many times it has gone through, and than acting based on -that- action. But I would rather not do that, since it's not really a solution to the problem at hand but a work around. Any input is appreciated.

  • Is there a way to check if a div has the same class as an ancestor in jQuery?

    - by T.R.
    I'm looking to dynamically highlight a tab, if it represents the current page. I have: <style> #tabs li{bg-color: white;} body.Page1 #tabs .Page1, body.Page2 #tabs .Page2, body.Page3 #tabs .Page3{bg-color: orange;} </style> <body class="Page1 ADifferentClass"> <ul id="tabs"> <li class="Page1 SomeClass"> <li class="Page2 SomeOtherClass"> <li class="Page3 AnotherClass"> </ul> </body> As you can see, there needs to be CSS for each tab, so adding another page involves modifying both the HTML and the CSS. Is there a simple (DRY) way to check if two divs have the same class already built into jQuery? I ultimately went with this: <script> $(document).ready(function(){ var classRE = /Page\d+/i; var pageType = $('body').attr('className').match(classRE); $('li.'+pageType).addClass('Highlight'); }); </script> <style> #tabs li{bg-color: white;} #tabs li.Highlight{bg-color: orange;} </style>

Iam happy! Why not the same happens when i try to do from the browser (i tested in IE6 & Chrome) using javascript:document.getElementById("myInput").type="text" different browsers behave in different way... when i tried javascript:document.getElementById("myInput").value="myNewValue", IE6 changes the value, but chrome doesn't.. Why is this "javascript:" behaving like this ?

  • Refactor link to show/hide a table row

    I have a table with row which cab be hidden by user. It's implemented this way: Markup: <table> <tr> <td> <table style="margin-left: auto; text-align: right;"> <tr> <td class="stats-hide"> <a href="#" onclick="hideStats();">Hide</a> </td> <td class="stats-show" style="display: none;"> <a href="#" onclick="showStats();">Show</a> </td> </tr> </table> </td> </tr> <tr class="stats-hide"> <td> <!-- data --> </td> </tr> </table> And jQuery code: <script type="text/javascript" language="javascript"> function hideStats() { hideControls(true, $('.stats-hide')); hideControls(false, $('.stats-show')); } function showStats() { hideControls(false, $('.stats-hide')); hideControls(true, $('.stats-show')); } function hideControls(value, arr) { $(arr).each(function () { if (value) { $(this).hide(); } else { $(this).show(); } }); } </script> How to implement the same behavior with one, single link and one, probably, CSS class? My idea - store somewhere a boolean variable and toggle controls visibility relatively to this variable. Are there more?

  • LALR(1) or GLR on Windows - Alternatives to Bison++ / Flex++ that are current?

    - by mrjoltcola
    I have been using the same version of bison++ (1.21-8) and flex++ (2.3.8-7) since 2002. I'm not looking for an alternative to LALR(1) or GLR at this time, just looking for the most current options. Is anyone aware of any later ports of these than the original that aren't Cygwin dependent? What are other folks using in Windows environments for C++ compiler development (besides ANTLR or Boost.spirit)? Commercial options are ok, if you have firsthand experience. I do need to compile on Linux as well.

  • Sql query builder c# for windows mobile

    - by pdiddy
    I'm building a windows mobile app. And using SqlCe. I'm looking for a good sql query builder. So instead of writing "SELECT COLUMNS FROM TABLE WHERE etc... Is there a good free library that can build this sort of query? EDIT: You know when you write your code with ADO.net something like this SqlCeCommand command = new SqlCeCommand(Connection); command.CommandText = "SELECT * FROM Orders WHERE customerId = @customerId"; Well i'm looking for some library that could build that SELECT statement using classes instead of writing it through string. So something like: SqlCeCommand command = new SqlCeCommand(Connection); SqlQueryBuilder query = new SqlQueryBuilder(); query.Table = "Orders"; query.AddWhere("customerId", myValue) command.CommandText = query.toString(); Something like that .... so a class that will build the query..

  • How to write automated tests for SQL queries?

    - by James
    The current system we are adopting at work is to write some extremely complex queries which perform multiple calculations and have multiple joins / sub-queries. I don't think I am experienced enough to say if this is correct or not so I am agreeing and attempting to function with this system as it has clear benefits. The problem we are having at the moment is that the person writing the queries makes a lot of mistakes and assumes everything is correct. We have now assigned a tester to analyse all of the queries but this still proves extremely time consuming and stressful. I would like to know how we could create an automated procedure (without specifically writing it with code if possible as I can work out how to do that the long way) to verify a set of 10+ different inputs, verify the output data and say if the calculations are correct. I know I could write a script using specific data in the database and create a script using c# (the db is SQL Server) and verify all the values coming out but I would like to know what the official "standard" is as my experience is lacking in this area and I would like to improve. I am happy to add more information if required, add a comment if necessary. Thank you. Edit: I am using c#

  • Get variable name as string in Perl

    - by Jose Cuervo
    Hi, I am trying to get a text representation of a variable's name. For instance, this would be the function I am looking for: $abc = '123'; $var_name = &get_var_name($abc); #returns '$abc' I want this because I am trying to write a debug function that recursively outputs the contents of a passed variable, I want it to output the variable's name before hand so if I call this debug function 100 times in succession there will be no confusion as to which variable I am looking at in the output. I have heard of Data::Dumper and am not a fan. If someone can tell me how to if it's possible get a string of a variable's name, that would be great. Thanks!

  • Canvas maximization bug?

    - by mitjak
    I must've killed over an hour on what seems to me like strange behaviour that happens in Firefox, Safari and Chrome. Here is some code: <!doctype html> <html> <head> <title>Watch me grow scrollbars!</title> </head> <body onload="resizeCanvas()"> <canvas id="canvas"></canvas> </body> </html> <script type="application/javascript"> function resizeCanvas() { var canvas = document.getElementById("canvas"); canvas.setAttribute("height", window.innerHeight); canvas.setAttribute("width", window.innerWidth); } </script> Basically, the canvas always seems to maximize 'too much', and the window grows scrollbars on both sides. I've tried using various ways of obtaining the document dimensions, including nesting canvas in a 100% wide & tall absolutely positioned div, as well as extracting the document.documentElement.clientWidth/Height properties. Just to be sure I'm not going insane, I've placed an image in place of the canvas, and voila, the same code worked perfectly to stretch the image out to document dimensions. What am I doing wrong here? I'm too tired to understand. Must.. drink.. something.
