  • calling Valums Ajax uploader from other DOM element

    - by Marc
    I'm facing a problem with the valums Ajax File upload. Since the plugin is working perfectly after a few modifications on the server side, I cannot implement a specific behavior. My DOM is composed with an input file plus the container to instantiate the fileuploader buttons. What I want is to be able to fire the fileuploader plugins when clicking on the input:file[name="upload-file"]. ... <div id="upload-accepted"> <fieldset> <label for="upload-file">Select a file:</label> <input type="file" name="upload-file" id="upload-file"/> <noscript> <p>Please enable JavaScript to use file uploader.</p> </noscript> </fieldset> <div id="upload-container"> </div> </div> ... <script type="text/javascript"> $(function() { var uploader = new qq.FileUploader({ action: '/file-upload', element: document.getElementById('upload-container'), onSubmit: function(id, filename){...}, onComplete: function(id, fileName, responseJSON){...} }); }); </script> I have tried to add the following on the script but it don't works $("#upload-file").live('change', function(event) { event.preventDefault(); $('.qq-upload-button').trigger('click'); return false; }); Any clues? Thanks in advance!

  • Dojo: dojo onblur events

    - by Jane Wilkie
    Hi guys, I have a form setup with dojo 1.5. I am using a dijit.form.ComboBox and a dijit.form.TextBox The Combobox has values like "car","bike","motorcycle" and the textbox is meant to be an adjective to the Combobox. So it doesn't matter what is in the Combobox but if the ComboBox does have a value then something MUST be filled in the TextBox. Optionally, if nothing is in the ComboBox, then nothing can be in the TextBox and that is just fine. In fact if something isn't in the Combobox then nothing MUST be in the text box. In regular coding I would just use an onBlur event on the text box to go to a function that checks to see if the ComboBox has a value. I see in dojo that this doesn't work... Code example is below... Vehicle: <input dojoType="dijit.form.ComboBox" store="xvarStore" value="" searchAttr="name" name="vehicle_1" id="vehicle_1" /> Descriptor: <input type="text" dojoType="dijit.form.TextBox" value="" class=lighttext style="width:350px;height:19px" id="filter_value_1" name="filter_value_1" /> My initial attempt was to add an onBlur within the Descriptor's <input> tag but discovered that that doesn't work. How does Dojo handle this? Is it via a dojo.connect parameter? Even though in the example above the combobox has an id of "vehicle_1" and the text box has an id of "filter_value_1", there can be numerous comboboxes and textboxes numbering sequentially upward. (vehicle_2, vehicle_3, etc) Any advice or links to resources would be greatly appreciated. Janie

  • Post a form from asp to asp.Net

    - by Atomiton
    I have a classic asp application. I want to post a contest form from that page to an Asp.Net form. The reason is that I want to use a lot of logic i have built into an Asp.Net page for validation before entering into the database and I don't know asp very well. Not to mention asp.Net being more secure. What's the best way to accomplish this goal? My thoughts are as follows: My asp Page: <html> <body> <form action="/Contests/entry.aspx" method="post"> Name: <input type="text" name="fname" size="20" /> Last Name: <input type="text" name="lname" size="20" /> <input type="submit" value="Submit" /> </form> </body> </html> aspx page is running in a Virtual Directory and would handle anything posted to it. Is this possible, or does aspx prevent this kind of thing? I ( preferably ) don't want to create the form in aspx as my colleague wants to have control of the page and build the html himself and I don't want the hassle of constantly changing it. Are there caveats I need to consider? What roadblocks will I run into? How do I access the Posted Form Values? Request.Form?

  • App starts in 1.5 emulator but doesn't in 1.6

    - by DixieFlatline
    My app works on 1.5 emulator and 1.5 device. When i try to start it on 1.6 emulator, it produces strange exceptions (doesn't even start). I don't have any 1.6 device to try this app if it works on a real device. I get some warnings in Eclipse ( warning: Ignoring InnerClasses attribute for an anonymous inner class that doesn't come with an associated EnclosingMethod attribute. This class was probably produced by a broken compiler.) and get cant rid of them (i think they come from some apache jars that i need to make http multipart posts). Is it possible that this jars are cause for my exceptions in 1.6 or is it something else? My logacat: 04-29 16:14:55.874: ERROR/AndroidRuntime(392): Uncaught handler: thread main exiting due to uncaught exception 04-29 16:14:55.894: ERROR/AndroidRuntime(392): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.poslji.gor/com.poslji.gor.FormFiller}: java.lang.NumberFormatException: unable to parse 'null' as integer 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2401) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2417) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at android.app.ActivityThread.access$2100(ActivityThread.java:116) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1794) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at android.os.Handler.dispatchMessage(Handler.java:99) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at android.os.Looper.loop(Looper.java:123) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at android.app.ActivityThread.main(ActivityThread.java:4203) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at java.lang.reflect.Method.invokeNative(Native Method) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at java.lang.reflect.Method.invoke(Method.java:521) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:791) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:549) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at dalvik.system.NativeStart.main(Native Method) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): Caused by: java.lang.NumberFormatException: unable to parse 'null' as integer 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at java.lang.Integer.parseInt(Integer.java:358) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at java.lang.Integer.parseInt(Integer.java:333) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at com.poslji.gor.FormFiller.nastavi(FormFiller.java:322) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at com.poslji.gor.FormFiller.onCreate(FormFiller.java:188) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1123) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2364)

  • App store name and info.plist

    - by user346194
    Hi guys, I've just completed my first app and having tested I'm ready for submission. However, despite numerous web searches and reading, I'm struggling to finalise the method required to enable me to have a different name on the app store to the name that appears under the app on the device home screen. In the plist.info file there is reference to bundle display name, executable name, bundle name, bundle identifier, product name etc. So, for example, say I would like the app store name to display as: HELLO WORLD and I would like the name below the icon on the device home screen to display as: HELLO How should I enter the data in the plist.info file to achieve the above? Many thanks in advance for your help. Gav.

  • JQuery UI Autocomplete showing as bullets

    - by awshepard
    The JQuery UI Demo page for autocomplete (link) has a nice looking search box and drop down with nice colors and highlights and such. When I implement it for myself, I end up with a bulleted list. How do I get my drop down of suggestions to look like theirs? A few notes/code fragments: I'm working in .NET land, so I'm using the <asp:ScriptManager> tag with <asp:ScriptReference>s inside it to get the hosted jquery.min.js (1.4.2) and jquery-ui.min.js (1.8.1) files from Google. My input box is fairly simple: <div class='ui-widget'> <label for="terms">Term: </label> <input id="terms" class="ui-autocomplete-input"> </div> My autocomplete looks like: $(""#terms"").autocomplete({source:""GetAttributesJSON.aspx"",minLength:2}); I get the correct data back, so that's not the issue. I just want fancy graphics. Any thoughts would be much appreciated.

  • Ajax/PHP contact form not able to send mail

    - by Steph
    The funny thing is it did work for one evening. I contacted my host, and they are saying there's no reason it should not be working. I have also attempted to test it in Firebug, but it seemed to be sending. And I specifically put the email address (hosted in my domain) on my email safe list, so that is not the culprit either. Would anyone here take a look at it for me? I'd be so grateful. In the header I have: <script type="text/javascript"> $(document).ready(function() { var options = { target: '#alert' }; $('#contactForm').ajaxForm(options); }); $.fn.clearForm = function() { return this.each(function() { var type = this.type, tag = this.tagName.toLowerCase(); if (tag == 'form') return $(':input',this).clearForm(); if (type == 'text' || type == 'password' || tag == 'textarea') this.value = ''; else if (type == 'checkbox' || type == 'radio') this.checked = false; else if (tag == 'select') this.selectedIndex = -1; }); }; </script> Here is the actual form: <form id="contactForm" method="post" action="sendmail.php"> <fieldset> <p>Email Me</p> <div id="fieldset_container"> <label for="name">Your Name:</label> <input type="text" name="name" id="name" /><br /><br /> <label for="email">Email:</label> <input type="text" name="email" id="email" /><br /><br /> <span style="display:none;"> <label for="last">Honeypot:</label> <input type="text" name="last" value="" id="last" /> </span><br /><br /> <label for="message">Comments &amp; Inquiries:</label> <textarea name="message" id="message" cols="" rows=""></textarea><br/> </div> <div id="submit_button"> <input type="submit" name="submit" id="submit" value="Send It" /> </div> </fieldset> </form> <div class="message"><div id="alert"></div></div> Here is the code from my validating page, sendmail.php: <?php // Who you want to recieve the emails from the form.

  • Set predefine form value (webbrowser control)

    - by Khou
    Hi I want to load my windows form: web browser thats using the webbrowser control, It would load a web page, and load my defination and search for elements that has been define, it will then assign the default values and these values can not be changed by the end user. Example If my application finds "FirstName" it would always assign the value "John" If my application finds "LastName" it would always assign the value "Smith" (these values should not be changed by the end user). Here's how to do it in HTML/JAVASCRIPT, but how do i do this in a windows form? HTML <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html> <head> <title>page title</title> <script script type="text/javascript" src="demo1.js"></script> </head> <body onload="def(document.someform, 'name', 'my default name value');"> <h2 style="color: #8e9182">test form title</h2> <form name="someform" id="someform_frm" action="#"> <table cellspacing="1"> <tr><td><label for="name">NameX: </label></td><td><input type="text" size="30" maxlength="155" name="name" onchange="def(document.someform, 'name', 'my default name value');"></td></tr> <tr><td><label for="name2">NameY: </label></td><td><input type="text" size="30" maxlength="155" name="name2"></td></tr> <tr><td colspan="2"><input type="button" name="submit" value="Submit" onclick="showFormData(this.form);" ></td></table> </form> </body> </html> JAVASCRIPT function def(oForm, element_name, def_txt) { oForm.elements[element_name].value = def_txt; }

  • problem with two .NET threads and hardware access

    - by mack369
    I'm creating an application which communicates with the device via FT2232H USB/RS232 converter. For communication I'm using FTD2XX_NET.dll library from FTDI website. I'm using two threads: first thread continuously reads data from the device the second thread is the main thread of the Windows Form Application I've got a problem when I'm trying to write any data to the device while the receiver's thread is running. The main thread simply hangs up on ftdiDevice.Write function. I tried to synchronize both threads so that only one thread can use Read/Write function at the same time, but it didn't help. Below code responsible for the communication. Note that following functions are methods of FtdiPort class. Receiver's thread private void receiverLoop() { if (this.DataReceivedHandler == null) { throw new BackendException("dataReceived delegate is not set"); } FTDI.FT_STATUS ftStatus = FTDI.FT_STATUS.FT_OK; byte[] readBytes = new byte[this.ReadBufferSize]; while (true) { lock (FtdiPort.threadLocker) { UInt32 numBytesRead = 0; ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead); if (ftStatus == FTDI.FT_STATUS.FT_OK) { this.DataReceivedHandler(readBytes, numBytesRead); } else { Trace.WriteLine(String.Format("Couldn't read data from ftdi: status {0}", ftStatus)); Thread.Sleep(10); } } Thread.Sleep(this.RXThreadDelay); } } Write function called from main thread public void Write(byte[] data, int length) { if (this.IsOpened) { uint i = 0; lock (FtdiPort.threadLocker) { this.ftdiDevice.Write(data, length, ref i); } Thread.Sleep(1); if (i != (int)length) { throw new BackendException("Couldnt send all data"); } } else { throw new BackendException("Port is closed"); } } Object used to synchronize two threads static Object threadLocker = new Object(); Method that starts the receiver's thread private void startReceiver() { if (this.DataReceivedHandler == null) { return; } if (this.IsOpened == false) { throw new BackendException("Trying to start listening for raw data while disconnected"); } this.receiverThread = new Thread(this.receiverLoop); //this.receiverThread.Name = "protocolListener"; this.receiverThread.IsBackground = true; this.receiverThread.Start(); } The ftdiDevice.Write function doesn't hang up if I comment following line: ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead);

  • Why won't .attr('checked','checked') set?

    - by Jason
    I have the following snippet of code (I'm using jQuery 1.4.2): $.post('/Ads/GetAdStatsRow/', { 'ad_id': id }, function(result) { $('#edit_ads_form tbody').prepend(result); $(result).find('td.select-ad input').attr('checked','checked').click(); }); Assume that the post works correctly and returns a correct pre-built <tr> with some <td>s. Here's the weirdness: the $(result).find() line finds the correct input (which is a checkbox, as it's the only input in the cell) and runs the chained click() function correctly, but it REFUSES to set the box as checked, which I need to happen. Here's a crazy twist, too... when I get super specific and change the $(result).find() line to this (the id of the checkbox): $('#ad_' + id).click(); It checks the box, but doesn't run the click() function! If I set it to $('#ad_' + id).attr('checked','checked').click(); it runs the click function as though the box were checked, but the box remains unchecked, and if I do $('#ad_' + id).click().attr('checked','checked'); it does nothing at all. What in the world could be the matter with this? I'm running out of hair.... Thanks!

  • Windows CE 5.0 emulator needed

    - by Heinzi
    I need an emulator for Windows CE 5.0 to test an embedded device (not PDA or smartphone) application that I am developing. This is what I have already tried: Visual Studio 2008 Pro includes an emulator. Unfortunately, it does not include a Windows CE image (only Windows Mobile and Smartphone). Yes, there is a difference, see the screenshots here. Windows CE includes a "start button", windows that can be minimized, moved around etc. There is a Windows CE Device Emulator available from Microsoft. Apart from the fact that its license only permits non-commercial use, it does not run in Windows 7 (it requires .net Framework 1.1, which is incompatible with Windows 7) nor in Windows XP mode (error message: "Emulator for Windows CE will not run one virtual machine within another. Please run the virtual machine on the host operating system"). Is there any option that I have missed?

  • iOS6 Twitter integration

    - by Peter Warbo
    There seems to be a difference between the iPhone simulator and actual device when checking if Twitter is available. I check if a Twitter account is setup by using this code: [SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]; In the simulator there is a nice UIAlertView informing the user that there are no Twitter accounts setup and two buttons one for Settings and one for Cancel. However when I run my app on my device it will not show the above UIAlertView. Why is that? And how can I catch what button is tapped in the above UIAlertView (since I did not instantiate it?) This is what it looks like on the simulator:

  • Is it possible to load ListPreference items from an adapter?

    - by Brad Hein
    I'm setting out to create a settings activity for my app. I've defined a PreferenceActivity with a nice layout including a ListPreference object for the user to select a bluetooth device. I'm having trouble dynamically populating the list. I would like to populate ListPreference with values from an array adapter (which I'll create and populate with relevant bluetooth device names). If this were a spinner View, I could just call setAdapter(). However with the ListPreference object I can't figure out how to attach an adapter (findviewByID won't cast from View To ListPreference, so I can't even get a handle to the object). I would like to attach an adapter and then populate the adapter with values, which in turn would populate the ListPreference with values.

  • iOS Efficiency File Saving Efficiency

    - by Guvvy Aba
    I was working on my iOS app and my goal is to save a file that I am receiving from the internet bit by bit. My current setup is that I have a NSMutableData object and I add a bit of data to it as I receive my file. After the last "packet" is received, I write the NSData to a file and the process is complete. I'm kind of worried that this isn't the ideal way to do it because of the limitations of RAM in a mobile device and it would be problematic to receive large files. My next thought was to implement a NSFileHandle so that as the file arrives, it would be saved to the disk, rather than the virtual memory. In terms of speed and efficiency, which method do you think will work decently on an iOS device. I am currently using the first, NSMutableData approach. Is it worth changing my app to use the NSFileHandle? Thanks in advance, Guvvy

  • Combine 3 select fields and validate as one in my User model in ruby on rails 3

    - by Psychonetics
    Ok I have 3 select boxes for selecting date of birth. I have constants setup in my User model to provide months, years etc.. Anyway I can successfully validate these select boxes separately. What I want to do is combine the :day, :month and :year and store in :birthday and validate the whole date as one so I can return 1 error rather than 3 separate ones. Also doing this will make it easier to store the validated date in my birthday field in my database. Part of my form <td> <%= f.input :day, :required => false, :label => "Birthday: " , :prompt => "Day", :collection => User::DAYS %></td> <td> <%= f.input :month, :label => false, :prompt => "Month", :collection => User::MONTHS %> </td> <td> <%= f.input :year, :label => false, :prompt => "Year", :collection => User::YEAR_RANGE %> </td> Part of User model MONTHS = ["January", 1], ["February", 2], ["March", 3], ["April", 4], ["May", 5], ["June", 6], ["July", 7], ["August", 8], ["September", 9], ["October", 10], ["November", 11], ["December", 12] # finish this DAYS = 1..31 # finish this START_YEAR = Time.now.year - 106 END_YEAR = Time.now.year YEAR_RANGE = START_YEAR..END_YEAR class User < ActiveRecord::Base attr_accessor :day, :month, :year validates_presence_of :day, :message = 'What day in a month was you born?' validates_presence_of :month, :message = 'What month was you born?' validates_presence_of :year, :message = 'What is your year of birth?' end

  • Array: mathematical sequence

    - by VaioIsBorn
    An array of integers A[i] (i 1) is defined in the following way: an element A[k] ( k 1) is the smallest number greater than A[k-1] such that the sum of its digits is equal to the sum of the digits of the number 4* A[k-1] . You need to write a program that calculates the N th number in this array based on the given first element A[1] . INPUT: In one line of standard input there are two numbers seperated with a single space: A[1] (1 <= A[1] <= 100) and N (1 <= N <= 10000). OUTPUT: The standard output should only contain a single integer A[N] , the Nth number of the defined sequence. Input: 7 4 Output: 79 Explanation: Elements of the array are as follows: 7, 19, 49, 79... and the 4th element is solution. I tried solving this by coding a separate function that for a given number A[k] calculates the sum of it's digits and finds the smallest number greater than A[k-1] as it says in the problem, but with no success. The first testing failed because of a memory limit, the second testing failed because of a time limit, and now i don't have any possible idea how to solve this. One friend suggested recursion, but i don't know how to set that. Anyone who can help me in any way please write, also suggest some ideas about using recursion/DP for solving this problem. Thanks.
