  • Changing html content of a div before and after ajax request

    - by R27
    I am trying to change the button "ADD" (in a div) to some text/img as soon as it is clicked. And after the ajax request is processed, in the success block , I want the div to get the button back. I see the ajax request is itself not getting processed. Can someone explain whats my mistake. I just removed the jsfiddle link and pasting the script here to avoid confusion about the dependencies. JS script var ajax_load = "Please wait..."; jQuery(document).ready(function($) { $("#add_button").click(function(event){ var st = $("#add_div").html(); $("#add_div").html(ajax_load); $("#sform").validate({ errorClass: "error", submitHandler: function (form) { alert('inside submit'); $.ajax({ type: "GET", url: 'form.cgi', data: $("#sform").serialize(), success: function (msg) { alert('msg'); $("#add_div").html(st); $("#sform")[0].reset(); } }); } }); }); }); And the html piece is <form id=sform>LABEL <input id=field1 type=text> <div id="add_div"> <input type="button" value="ADD" id="add_button"> </div> </form> I have jquery.validate.min.js script included.

  • Using generics in Unity ... InvalidCastException

    - by Sunny D
    Hi, My interface definition is: public interface IInterface where T:UserControl My class definition is: public partial class App1Control : UserControl, IInterface The unity section of my app.config looks as below: <unity> <typeAliases> <typeAlias alias="singleton" type="Microsoft.Practices.Unity.ContainerControlledLifetimeManager, Microsoft.Practices.Unity" /> <typeAlias alias="myInterface" type="MyApplication.IInterface`1, MyApplication" /> <typeAlias alias="App1" type="MyApplication.App1Control, MyApplication" /> </typeAliases> <containers> <container> <types> <type type="myInterface" mapTo="App1" name="Application 1"> <lifetime type="singleton"/> </type> </types> </container> </containers> </unity> The app runs fine but, the following code gives a InvalidCastException container.Resolve<IInterface<UserControl>>("Application 1"); The error message is : Unable to cast object of type 'MyApplication.App1Control' to type 'MyApplication.IInterface`1[System.Windows.Forms.UserControl]' I believe there is a minor mistake in my code ... but am not able to figure out what. Any thoughts?

  • Comparing textbox.text value to value in SQL Server

    - by Anicho
    Okay so I am trying to compare a login textbox password and username with a custom validator using linq to get information from the database it always returns false though on the validator could someone please tell me where my code below is going wrong. This will be very much appreciated... thank you in advanced... protected void LoginValidate(object source, ServerValidateEventArgs args) { TiamoDataContext context = new TiamoDataContext(); var UsernameCheck = from User in context.Users where User.Username == TextBoxLoginUsername.Text && User.Password == TextBoxLogInPassword.Text select User.Username; var PasswordCheck = from User in context.Users where User.Username == TextBoxLoginUsername.Text && User.Password == TextBoxLogInPassword.Text select User.Password; String test1 = PasswordCheck.ToString(); String test2 = UsernameCheck.ToString(); if (test1 == TextBoxLogInPassword.Text && test2 == TextBoxLoginUsername.Text) { args.IsValid = true; Session["Username"] = TextBoxLoginUsername; Response.Redirect("UserProfile.aspx"); } else { args.IsValid = false; } } I dont know where I am going wrong I know its most probably some sort of silly mistake and me being inexperienced at this...

  • exec() in BeanShell macro causes jEdit to hang when it returns non-zero exit code

    - by rossmeissl
    I have a jEdit BeanShell macro that runs my Markdown files through Maruku when I save them: if (buffer.getMode().toString().equals("markdown")) { cmd = "C:\\Ruby\\bin\\maruku.bat -o " + buffer.getDirectory() + buffer.getName().replaceAll("markdown$", "html") + " " + buffer.getPath(); exec(cmd); } This works great when the Markdown file is valid. But if I've made a mistake, jEdit just waits around forever for the exec() call to "succeed," which it never will. When this happens, I have to kill jEdit's javaw.exe process and run Maruku manually from the command line to discover the error, e.g.: E:\bp\plan\supply_chain>maruku business_plan.markdown ___________________________________________________________________________ | Maruku tells you: +--------------------------------------------------------------------------- | Could not find ref_id = "17" for md_link(["17"],"17") | Available refs are [] +--------------------------------------------------------------------------- !C:/Ruby/lib/ruby/gems/1.8/gems/maruku-0.6.0/lib/maruku/errors_management.rb:49:in `maruku_error' !C:/Ruby/lib/ruby/gems/1.8/gems/maruku-0.6.0/lib/maruku/output/to_html.rb:716:in `to_html_link' !C:/Ruby/lib/ruby/gems/1.8/gems/maruku-0.6.0/lib/maruku/output/to_html.rb:970:in `send' !C:/Ruby/lib/ruby/gems/1.8/gems/maruku-0.6.0/lib/maruku/output/to_html.rb:970:in `array_to_html' !C:/Ruby/lib/ruby/gems/1.8/gems/maruku-0.6.0/lib/maruku/output/to_html.rb:961:in `each' \___________________________________________________________________________ Not creating a link for ref_id = "17". Then I restart jEdit, fix the error, and re-save the file, at which point the macro succeeds. How can I make my macro more resilient to either die helpfully (display Maruku's error output) or, at the very least, die silently so I don't have to kill jEdit?

  • strange chi-square result using scikit_learn with feature matrix

  • Efficient way to update SQL 'relationship' table

    - by AmbroseChapel
    Say I have three properly normalised tables. One of people, one of qualifications and one mapping people to qualifications: People: id | Name ---------- 1 | Alice 2 | Bob Degrees: id | Name --------- 1 | PhD 2 | MA People-to-degrees: person_id | degree_id --------------------- 1 | 2 # Alice has an MA 2 | 1 # Bob has a PhD So then I have to update this mapping via my web interface. (I made a mistake. Bob has a BA, not a PhD, and Alice just got her B Eng.) There are four possible states of these one-to-many relationship mappings: was true before, should now be false was false before, should now be true was true before, should remain true was false before, should remain false what I don't want to do is read the values from four checkboxes, then hit the database four times to say "Did Bob have a BA before? Well he does now." "Did Bob have PhD before? Because he doesn't any more" and so on. How do other people address this issue? I'm curious to see if someone else arrives at the same solution I did.

  • Is there only one distribution certificate per team leader or one per application?

    - by dbonneville
    I'm confused by the dev and dist cert. I got one app in the store, but I named my certs after my first app. Was this a mistake? I'm ready to go on my second app. But XCode is selected the dist cert with the old app name on it. It built without error. Though I named it wrong, will it still work? XCode is automatically picking this cert for me. Is this right? You need a new app ID for each app so you can 1) put in plist, 2) put in code signing section on Build tab of Target info, but you don't need a new dev and dist cert for each new app. Therefore is this right too? For each app you develop, you only need your original dev and dist cert, but a new app ID for each app. This is so obscure! I wish apple had done a better job!

  • Java MySQL Query Problem MySQLSyntaxErrorException When Creating a Table

    - by Aqib Mushtaq
    I fairly new to MySQL with Java, but I have executed a few successful INSERT queries however cannot seem to get the CREATE TABLE query to execute without getting the 'MySQLSyntaxErrorException' exception. My code is as follows: import java.sql.*; Statement stmt; Class.forName("com.mysql.jdbc.Driver"); String url = "jdbc:mysql://localhost:3306/mysql"; Connection con = DriverManager.getConnection(url, "root", "password"); stmt = con.createStatement(); String tblSQL = "CREATE TABLE IF NOT EXISTS \'dev\'.\'testTable\' (\n" + " \'id\' int(11) NOT NULL AUTO_INCREMENT,\n" + " \'date\' smallint(6) NOT NULL\n" + ") ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;"; stmt.executeUpdate(tblSQL); stmt.close(); con.close(); And the error is as follows: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''dev'.'testTable' ( 'id' int(11) NOT NULL AUTO_INCREMENT, 'date' smallint(6) N' at line 1 I would appreciate it if anyone could spot the mistake in this query, as I've tried executing this within phpMyAdmin and it works as it should. Thanks in advance.

  • In C#, are event handler arguments contravariant?

    - by Roger Lipscombe
    If I have a class that raises an event, with (e.g.) FrobbingEventArgs, am I allowed to handle it with a method that takes EventArgs? Here's some code: class Program { static void Main(string[] args) { Frobber frobber = new Frobber(); frobber.Frobbing += FrobberOnFrobbing; frobber.Frob(); } private static void FrobberOnFrobbing(object sender, EventArgs e) { // Do something interesting. Note that the parameter is 'EventArgs'. } } internal class Frobber { public event EventHandler<FrobbingEventArgs> Frobbing; public event EventHandler<FrobbedEventArgs> Frobbed; public void Frob() { OnFrobbing(); // Frob. OnFrobbed(); } private void OnFrobbing() { var handler = Frobbing; if (handler != null) handler(this, new FrobbingEventArgs()); } private void OnFrobbed() { var handler = Frobbed; if (handler != null) handler(this, new FrobbedEventArgs()); } } internal class FrobbedEventArgs : EventArgs { } internal class FrobbingEventArgs : EventArgs { } The reason I ask is that ReSharper seems to have a problem with (what looks like) the equivalent in XAML, and I'm wondering if it's a bug in ReSharper, or a mistake in my understanding of C#.

  • Setting routes in application.ini in Zend Framework

    - by Paul Watson
    I'm a Zend Framework newbie, and I'm trying to work out how to add another route to my application.ini file. I currently have my routes set up as follows: resources.router.routes.artists.route = /artists/:stub resources.router.routes.artists.defaults.controller = artists resources.router.routes.artists.defaults.action = display ...so that /artists/joe-bloggs uses the "display" action of the "artists" controller to dipslay the profile the artist in question - that works fine. What I want to do now is to set up another route so that /artists/joe-bloggs/random-gallery-name goes to the "galleries" action of the "artists" controller. I tried adding an additional block to the application.ini file (beneath the block above) like so: resources.router.routes.artists.route = /artists/:stub/:gallery resources.router.routes.artists.defaults.controller = artists resources.router.routes.artists.defaults.action = galleries ...but when I do that the page at /artists/joe-bloggs no longer works (Zend tries to route it to the "joe-bloggs" controller). How do I set up the routes in application.ini so that I can change the action of the "artists" controller depending on whether "/:gallery" exists? I realise I'm probably making a really stupid mistake, so please point out my stupidity and set me on the right path (no pun intended).

  • how to convert byte array to image in java?

    - by nemade-vipin
    I am developing a Web application in Java. In that application, I have created webservices in Java. In that webservice, I have created one webmethod which returns the image list in base64 format. The return type of the method is Vector. In webservice tester I can see the SOAP response as xsi:type="xs:base64Binary". Then I called this webmethod in my application. I used the following code: SBTSWebService webService = null; List imageArray = null; List imageList = null; webService = new SBTSWebService(); imageArray = webService.getSBTSWebPort().getAddvertisementImage(); Iterator itr = imageArray.iterator(); while(itr.hasNext()) { String img = (String)itr.next(); byte[] bytearray = Base64.decode(img); BufferedImage imag=ImageIO.read(new ByteArrayInputStream(bytearray)); imageList.add(imag); } In this code I am receiving the error: java.lang.ClassCastException: [B cannot be cast to java.lang.String" on line String img = (String)itr.next(); Is there any mistake in my code? Or is there any other way to bring the image in actual format? Can you provide me the code or link through which I can resolve the above issue? Note:- I already droped this question and I got the suggetion to try the following code Object next = iter.next(); System.out.println(next.getClass()) I tried this code and got the output as byte[] from webservice. but I am not able to convert this byte array to actual image. is there any other way to bring the image in actual format? Can you provide me the code or link through which I can resolve the above issue?

  • How to pass Event as a parameter in JQuery function

    - by Manas Saha
    Hi I am learning JQuery and I have written a small function where I am attaching a function with a button's click event. this is the head element of the HTML <script type="text/javascript"> $(pageLoaded); function pageLoaded() { $("#Button1").bind("click", { key1: "value1", key2: "value2" }, function buttonClick(event) { $("#displayArea").text(event.data.key1); } ); } </script> This is the body of the HTML <input id="Button1" type="button" value="button" /> <div id = "displayArea" style="border:2px solid black; width:300px; height:200px"> This code works fine. But when I try to write the buttonClick function outside the anonymus method, it does not work anymore. I tried to call it this way: $("#Button1").bind("click", { key1: "value1", key2: "value2" }, buttonClick(event)); function buttonClick(var event) { $("#displayArea").text(event.data.key1); } This is not working. Am I doing some mistake while passing the Event as parameter? what is the correct way to do it without using anonymous methods?

  • Hiring my first employee

    - by Ady
    A few years ago I moved to a new job having been programming for 2 years using C#, however this new company was mainly using VB6. I made the case for .NET and won, but one of the consessions I had to make was to use VB.NET and not C# (understandable as most of the other developers were already using VB). Three years later it was time to move on, but when applying for jobs I couldn't get past the recruitment agents. I realised that when they were looking at the basic requirements (5 years experience) that they could not add 2 and 3 together to make 5. They were looking for 5 years in VB or C# not across both. Frustrated I decided to combine my skills with a designer friend and start my own company. After two years of hard graft we are now looking for our first employee (a programmer), and this question has hit me again, but now I see the employers perspective. Why take the risk of someone getting up to speed when you have thousands of applicants to choose from. So my question is this, if I define the requirements to be too narrow, I could miss the really great candidates. But if they are too broad it's going to take ages to go through them all. This will be our first 'employee' so the choice needs to be good, I can't afford to make a mistake and employ someone naff. Another option would be to choose a bright university graduate, and train them up (less of a risk because we can pay them less). What have others done in this situation, and what would you recommend I do?

  • What is the most efficient/elegant way to parse a flat table into a tree?

    - by Tomalak
    Assume you have a flat table that stores an ordered tree hierarchy: Id Name ParentId Order 1 'Node 1' 0 10 2 'Node 1.1' 1 10 3 'Node 2' 0 20 4 'Node 1.1.1' 2 10 5 'Node 2.1' 3 10 6 'Node 1.2' 1 20 What minimalistic approach would you use to output that to HTML (or text, for that matter) as a correctly ordered, correctly intended tree? Assume further you only have basic data structures (arrays and hashmaps), no fancy objects with parent/children references, no ORM, no framework, just your two hands. The table is represented as a result set, which can be accessed randomly. Pseudo code or plain English is okay, this is purely a conceptional question. Bonus question: Is there a fundamentally better way to store a tree structure like this in a RDBMS? EDITS AND ADDITIONS To answer one commenter's (Mark Bessey's) question: A root node is not necessary, because it is never going to be displayed anyway. ParentId = 0 is the convention to express "these are top level". The Order column defines how nodes with the same parent are going to be sorted. The "result set" I spoke of can be pictured as an array of hashmaps (to stay in that terminology). For my example was meant to be already there. Some answers go the extra mile and construct it first, but thats okay. The tree can be arbitrarily deep. Each node can have N children. I did not exactly have a "millions of entries" tree in mind, though. Don't mistake my choice of node naming ('Node 1.1.1') for something to rely on. The nodes could equally well be called 'Frank' or 'Bob', no naming structure is implied, this was merely to make it readable. I have posted my own solution so you guys can pull it to pieces.

  • Validating age field

    - by Marcelo
    Hi people, I'm trying to validate an age field in a form but I'm having some problem. First I tried to make sure that the field will not be send empty. I don't know JavaScript so I searched some scripts and adapted them to this: function isInteger (s) { var i; if (isEmpty(s)) if (isInteger.arguments.length == 1) return 0; else return (isInteger.arguments[1] == true); for (i = 0; i < s.length; i++) { var c = s.charAt(i); if (!isDigit(c)) return false; } return true; } function isEmpty(s) { return ((s == null) || (s.length == 0)) } function validate_required(field,alerttxt) { with (field) { if (value==null||value=="") { alert(alerttxt);return false; } else { return true; } } } function validate_form(thisform) { with (thisform) { if ((validate_required(age,"Age must be filled out!")==false) || isInteger(age,"Age must be and int number")==false)) {email.focus();return false;} } } //html part <form action="doador.php" onsubmit="return validate_form(this)" method="post"> It's working fine for empty fields, but if I type any letters or characters in age field, it'll be sent and saved a 0 in my database. Can anyone help me? Sorry for any mistake in English, and thanks in anvance for your help.

    I'm facing some troubles to pass php variables value trough functions,every time i try to use a variable inside one of my functions its value becomes nil,let me be more specific.I have the following code in my php file: $myvar = $Session['username']; function updateuserinformation(){ if(trim($_FILES["fileUpload"]["tmp_name"]) != ""){ $images = $_FILES["fileUpload"]["tmp_name"]; $new_images = "thumbnails_".$_FILES["fileUpload"]["name"]; copy($_FILES["fileUpload"]["tmp_name"],"Photos/".$_FILES["fileUpload"]["name"]); $width=200; //*** Fix Width & Heigh (Autu caculate) ***// $size=GetimageSize($images); $height=round($width*$size[1]/$size[0]); $images_orig = ImageCreateFromJPEG($images); $photoX = ImagesX($images_orig); $photoY = ImagesY($images_orig); $images_fin = ImageCreateTrueColor($width, $height); ImageCopyResampled($images_fin, $images_orig, 0, 0, 0, 0, $width+1, $height+1, $photoX, $photoY); ImageJPEG($images_fin,"Photos/".$new_images); ImageDestroy($images_orig); ImageDestroy($images_fin); print $data["foo"]; echo"$myvar"; mysql_query("UPDATE users SET userpictureaddress = 'http://www.litsdevelopment.com/litsapplication/userimages/MATEUS' WHERE username = 'Mateus' "); } } I trying to use the $myvar value in my function but every time i run the code it just doesn't work,i've already tried global,globals,arrays and session for nothing worked.Of corse i'm making a little mistake in some part of it,but anyone know what is the correct way to do this?

  • live.com setting can't be changed

    - by M M
    I'm on mail.live.com where, in the upper left corner it says "Windows Live™" and to the right of that it says "Hotmail([number])" "Messenger" "SkyDrive" "|" "MSN." Directly under the "Windows Live™," there is a square, bluish/gray avatar (with a generic, rotund peop with a head and trunk and arms). To the right of that there is a field (with a subtle, barely perceptible speech bubble-like arrow emanating from the avatar). But there's a word inside that field that I cannot get rid of. Coincidentally I think it's the same word I used as a search term a while back, having meant to put the search term in the "Search email and more" bing field on the other side of the screen. (Even that would have been by mistake because I had been aiming for the e-mail search field.) But it remains in the field connected to the avatar--and moreover the field is editable to the limited extent that a cursor can be placed into the field with a mouse click; the word just can't be deleted. I don't know if the avatar should be there either, but I'd rather have just simply that than the word next to it continuously there for time immemorial. If I click into the field hoping to delete the word, I'm confronted with options along the bottom of the same field (now expanded by my mouse click): "Add: Photo Link Document," and a button that says "Share" and an [X] to reduce the field back to its default state--which still contains the word I'm trying to delete.

  • steps to fix a project that won't compile

    - by eco_bach
    Hi Pulling my hair out in trying to get a simple window based project to compile. I am running both 3.2.2 and 3.2.3 versions of Xcode. The latter is set up in a separate folder. Originally I used the latter to create and compile my project against the new 4.0 sdk. It compiled fine. Then I made the mistake of deleting some sdks I thought I no longer needed. Ever since I can no longer compile. Right now I get a dozen or so errors similar to the following "_OBJC_CLASS_$_CATransition", referenced from: objc-class-ref-to-CATransition in ViewTransitionsAppDelegate.o My active executable is the iphone simulator 4 and Base SDK is iPhone device 3.0. I tried reinstalling the xcode3.2.3 installer, no difference. I'm totally stymied, as my project WAS working and compiling fine, both to the simulator and external device. Are there any best practices or recommended steps in fixing or rebuilding a project when it won't compile? Any help welcome!

  • Validating Login / Changing User settings / Php Mysql

    - by Marcelo
    Hi everyone, my questions are about login, and changing already saved data. (Q1) 'Till now I've only saved input in the tables of the database (registration steps), now I need to check if the input (login steps), are the same of my table in database, in fact I have 3 types of users, then I'll have to check 3 kind of tables. Then if the input data matches with one of those 3 tables I will redirect the user to his specific area. I'm thinking about saved the submitted data $login=$_REQUEST['login']; and $password=$_REQUEST['password']; and compare with the login column in the database. Then if the login matches, I'll compare the password submitted with the one in the row, not in the column. But I don't know how to do this search and comparison,neither what to use. Then if both matches I'll redirect the user. Else I'll send an login error message. (this I know how to do) (Q2) What if need to change an already saved user ? For example to change an email address. My changing user's data web page is exactly the same like the registration user web page. Can I load the already saved options and values of registration (table user for example). Then the user will change whatever he thinks it's necessary, and then when he submits the new information, they would not create a new row in my table, but just be overwritten the old information? How can I do this? Sorry for any mistake in English, and Thanks for the attention.

  • Bind a generic list to a listbox and also use a datatemplate

    - by muku
    Hello, I'm trying to implement something quite simple but I'm on my first steps in WPF and I'm having some problems. I have a class called Component which has a property called Vertices. Vertices is a generic List of type Point. What I want is to bind the vertices property to a listbox. This is easy by using this code in my XAML in the listbox declaration: ItemsSource="{Binding Path=Component.Vertices, Mode=OneWay, Converter={StaticResource verticesconverter},UpdateSourceTrigger=PropertyChanged}" The tricky part is when I try to create a datatemplate for the listbox. I want each row of the listbox to display a textbox with the values of the Vertex (Point.X, Point.Y) and a button to allow me to delete the item. Could you help me on the datatemplate definition. The code below doesn't work to bind the X,Y values into two separate textboxes. Could you point me on the mistake and why nothing is displayed in the textboxes? <ListBox ItemsSource="{Binding Path=Component.Vertices, Mode=OneWay,UpdateSourceTrigger=PropertyChanged}"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal" Margin="0,10,0,0"> <TextBox Text="{Binding X}" MinWidth="35" MaxWidth="35"/> <TextBox Text="{Binding Y}" MinWidth="35" MaxWidth="35"/> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> /ListBox>

  • Design of std::ifstream class

    - by Nawaz
    Those of us who have seen the beauty of STL try to use it as much as possible, and also encourage others to use it wherever we see them using raw pointers and arrays. Scott Meyers have written a whole book on STL, with title Effective STL. Yet what happened to the developers of ifstream that they preferred char* over std::string. I wonder why the first parameter of ifstream::open() is of type const char*, instead of const std::string &. Please have a look at it's signature: void open(const char * filename, ios_base::openmode mode = ios_base::in ); Why this? Why not this: void open(const string & filename, ios_base::openmode mode = ios_base::in ); Is this a serious mistake with the design? Or this design is deliberate? What could be the reason? I don't see any reason why they have preferred char* over std::string. Note we could still pass char* to the latter function that takes std::string. That's not a problem! By the way, I'm aware that ifstream is a typedef, so no comment on my title.:P. It looks short that is why I used it. The actual class template is : template<class _Elem,class _Traits> class basic_ifstream;

  • SIGABRT on iPhone when changing xib

    - by Boz
    I've just finished off an app for the iPhone which, until today, ran fine on the iPhone simulator and actual devices. I tried changing the xib which is loaded in the applicationDidFinishLaunching method in my application delegate class - all I did was change the string in initWithNibName. When I launch the app on the simulator, the Default.png image is shown, then the app crashes with an uncaught exception. When running on a device, the Default.png image is shown for about 10 seconds, the UI is never loaded and I get 'GDB: Program received signal: "SIGABRT".' on the Xcode status bar. Debugging shows that applicationDidFinishLaunching is never actually reached before the app crashes. Setting the starting xib back to the original solves the issue, but now I've made a change and saved it in the Interface Builder and the app shows the same issues as above - I've made no code changes at all. Is this a memory issue, or a known issue of a common mistake? NOTE: I've made no code changes whatsoever, and the only changes I've made to the xib are cosmetic, the IBOutlets are all intact.
