• How to get coordinates when iPhone is locked/sleeping?

  - by lionfly

  For normal situations, the didUpdateToLocation (of CLLocationManager) does not work any more when the lock/sleep button is pushed, and your app cannot get further newLocation coordinates during the locked period. However, some apps CAN track during the locked period, and they will show the correct route when you unlocked and see the Mapview. Obviously there are ways to get the coordinates during the locked period. How to get the coordinates when the iPhone is locked/sleeping? Who has hints and further info, please post. Thanks.

• Dynamically adding UserControl to list in ASP.NET

  - by darja

  I have UserControl, which is used for editing fields of some object. I had a page with this control, where user filled the fields, pressed "Submit" and object inserted in DB. And everything was Ok. But now user wants to insert several objects by one submit. So I need to implement dynamic adding of this control. What is the simpliest way to do it? The only way I see is to specify "+" button and to create control in its OnClick handler. But it is very dull. I think it is very common issue and there are better variants.

• How to validate a form with jQuery?

  - by vlad

  I tried to find the answer in other questions but actually nothing worked -.- Somehow I hate JavaScript ... Anyway! My Code looks like: function validate() { if ($(":input").length == 0) { $(":input").addClass("notvalid"); return false; } else { $(":input").removeClass("notvalid"); return true; } return true; } $(":input").blur(validate()); $(":input").keyup(validate()); $("#customForm").submit(function(){ if(validate()){ return true; } else { return false; } }); I just want to test every tag to be not empty. The test should be done when the focus is lost or after every key type. And of course after the submit button has been clicked. It doesn't work. Firefox error console says something like: unknown pseudoclass or pseudoelement 'input'. What does this mean?

• What Windows message is fired for mouse-up with modifier keys?

  - by Greg

  My WndProc isn't seeing mouse-up notifications when I click with a modifier key (shift or control) pressed. I see them without the modifier key, and I see mouse-down notifications with the modifier keys. I'm using the Windows Forms NativeWindow wrapper to get Windows messages from the WndProc() method. I've tried tracking the notifications I do get, and I the only clue I see is WM_CAPTURECHANGED. I've tried calling SetCapture when I receive the WM_LBUTTONDOWN message, but it doesn't help. Without modifier (skipping paint, timer and NCHITTEST messages): WM_LBUTTONDOWN WM_SETCURSOR WM_MOUSEMOVE WM_SETCURSOR WM_LBUTTONUP With modifier (skipping paint, timer and NCHITTEST messages): WM_KEYDOWN WM_PARENTNOTIFY WM_MOUSEACTIVATE WM_MOUSEACTIVATE WM_SETCURSOR WM_LBUTTONDOWN WM_SETCURSOR (repeats) WM_KEYDOWN (repeats) WM_KEYUP If I hold the mouse button down for a long time, I can usually get a WM_LBUTTONUP notification, but it should be possible to make it more responsive.. What am I missing? Thanks.

• Getting data from a ListView into an array

  - by Joe

  I have a ListView control on my form set up like this in details mode: What I would like to do, is get all the values of the data cells when the user presses the Delete booking button. So using the above example, my array would be filled with this data: values(0) = "asd" values(1) = "BS1" values(2) = "asd" values(3) = "21/04/2010" values(4) = "2" This is my code so far: Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim items As ListView.SelectedListViewItemCollection = _ Me.ManageList.SelectedItems Dim item As ListViewItem Dim values(0 To 4) As String Dim i As Integer = 0 For Each item In items values(i) = item.SubItems(i).Text i = i + 1 Next End Sub But only values(0) gets filled with the first data cell of the selection (in this case "asd") and the rest of the array entries are blank. I have confirmed this with a breakpoint and checked the array entries myself. I'm REALLY lost on this, and have been trying for about an hour now. Any help would be appreciated, thanks :) Also please note that there can only be one row selection at once. Thanks.

• How to Create a Queue

  - by regex

  Hello All, I have an application built that hits a third party company's web service in order to create an email account after a customer clicks a button. However, sometimes the web service takes longer than 1 minute to respond, which is way to long for my customers to be sitting there waiting for a response. I need to devise a way to set up some sort of queuing service external from the web site. This way I can add the web service action to the queue and advise the customer it may take up to 2 minutes to create the account. I'm curious of the best way to achieve this. My initial thought is to request the actions via a database table which will be checked on a regular basis by a Console app which is run via Windows Scheduled tasks. Any issues with that method? Is there a better method you can think of?

• Question regarding common class

  - by Rocky Singh

  I have following two classes: public class A : System.Web.UI.WebControls.Button { public virtual string X { get { object obj = ViewState["X"]; if (obj != null) return (string)obj; return null; } set { ViewState["X"] = value; } } protected override void OnLoad(EventArgs e) { X=2; } } and public class B : System.Web.UI.WebControls.TextBox { public virtual string X { get { object obj = ViewState["X"]; if (obj != null) return (string)obj; return null; } set { ViewState["X"] = value; } } protected override void OnLoad(EventArgs e) { X=2; } } As you must be seeing the class A and B have exactly the same code , my question is how can I make a common class for it and use these two classes.

• Jquery javascript - How can I let users 'undo' their modifications?

  - by Bill Zimmerman

  Hi, i have a basic jquery app that allows a user to edit and manipulate some lists on a page. What I would like to do is have a button 'restore original list' that the user can press to undo his modifications. What is the best way to do this? I was thinking of just copying the DOM from the list down, and pasting it in a hidden element someplace else on the page. Is this the best way to do this? I also noticed that jquery has a .data() function which I could use if I converted the data to an array and stored it this way. What are the advantages and disadvantages? Also, I'm open to any suggestions people have if there is some method I haven't thought of. Thanks for your help!

• How can I use html/javascript to make <a> link trigger an embedded flash object?

  - by MikeN

  Using HTML/Javascript I want to make an link trigger a flash object that is normally triggered by clicking on the flash itself. The flash objects is actually the "Call Me Now" button from Google Voice which looks something like: <object type="application/x-shockwave-flash" data="https://clients4.google.com/voice/embed/webCallButton" width="230" height="85"> <param name="movie" value="https://clients4.google.com/voice/embed/webCallButton"/> <param name="wmode" value="transparent" /><param name="FlashVars" /> </object> When you click on the object the first time it brings up a set of fields to enter your phone number in to make the call. So I want to be able to trigger that action by having a user click on a different link (which would actually be the phone number that the widget would call.)

• Resharper 5 - enable/disable on the fly

  - by Cristi Diaconescu

  I want to disable ReSharper 5 when debugging - it slows things down more than I'm willing to take. Is there an automatic way to do this? The next best thing would be a toolbar button to manually enable/disable it. On the Tools - Options - ReSharper page there's a comment that the VS command Resharper_ToggleSuspended would do just this. The problem is, I can't find the command when I right-click a toolbar - Customize... - 'Commands' tab - Choose 'Resharper' category. Am I missing something?

• This PHP/Smarty doesn't work in IE

  - by Kyle Sevenoaks

  I'm starting to get sick of IE's random problems. Page link. (Add things to the cart with the kjøp button and handlevogn) I have this little tiny code here, {foreach $cart.taxes.$currency as $tax} <div id="subTotalCaption2"><p style="width:100px;">{$tax.name_lang}:</p></div> <div id="taxAmount2"><p>{$tax.formattedAmount}</p></div> {/foreach} That's meant to display the amount of total tax for each of the items in the basket. (MVA 25%) This works in every other browser but not IE. Why? Why not? Just why? Any help at all would be very much appreciated.

• GUI design techniques to enhance user experience

  - by aku

  What techniques do you know\use to create user-friendly GUI ? I can name following techniques that I find especially useful: Non-blocking notifications (floating dialogs like in Firefox3 or Vista's pop-up messages in tray area) Absence of "Save" button MS OneNote as an example. IM clients can save conversation history automatically Integrated search Search not only through help files but rather make UI elements searchable. Vista made a good step toward such GUI. Scout addin Microsoft Office was a really great idea. Context oriented UI (Ribbon bar in MS Office 2007) Do you implement something like listed techniques in your software? Edit: As Ryan P mentioned, one of the best way to create usable app is to put yourself in user's place. I totally agree with it, but what I want to see in this topic is specific techniques (like those I mentioned above) rather than general recommendations.

• Update options to jQuery slider via form

  - by Coughlin

  I have a jQuery Slider, and I am trying to make it more dynamic by adding three input fields: min max step I want to take those fields and then onblur update my slider options. I read that you can set options like this: $('.selector').slider('option', 'max', 7); And do the same for min,step, etc along with the other options. I tried playing with it yesterday, but I'm not sure how to get it to update. I am using a form with no submit button, so just change on blur. I know I would get the .val() of the input and set it to a variable then would it be: $('.selector').slider('option', 'max', var_here); Any thoughts?

• Android: stack management for views in a tab?

  - by wei

  I see some answers here prefer views over activities as contents of tabs. Correct me if I am wrong. My understanding is that by switching out views, it's possible to keep the navigation flow inside a tab (more user friendly, I think). But I wonder how to manage the view stack then in case of the back button events. Also this could cause one giant Activity with large amount of views, which might not be good. So I wish to know why exactly views as contents is preferred before I change my current application to this. Thanks,

• Automating site interaction

  - by Leocer

  I'm working with a CMS and need to import data to it using typical html forms. The data itself is in csv files with one page per row. Such is the CMS that importing directly to db isn't possible due to the complexity of the design. It's pretty important that i "fake" usual user interaction because the CMS does a lot of background work that's crucial for the import. Basically, for each row in the csv file, I need to copy a csv column to a html textfield, or select a checkbox, or click a certain button. One major issue is mapping the data in the csv to actions in the CMS. So if one column contains the string 'foobar' is really means "set the firstName dropdown widget to 'foobar'". Is there a tool to automate this? I´ve been looking at AutoHotKey, Selendium, Web-Harvester and many other tools but I'm not convinced they are the correct tools. The main problem is being able to interact with the html pages in a easy way.

• Launching an activity at its current state.

  - by Profete162

  Hello, I am trying to make a task switcher and i succed in it. My only problem is that when I launch activities, they are relaunched as they were new activities ( for instance, I am writing an email, i press home and go into my activity,launch email, and then the app launch the email bout goes back at the inbox and the email is lost) So that's not true multitasking. Here are my steps: 1) getting all the running apps: List<ActivityManager.RunningTaskInfo> allTasks = activityManager.getRunningTasks(30); 2) getting the intent: for (ActivityManager.RunningTaskInfo aTask : allTasks) { Intent i = new Intent(Intent.ACTION_MAIN); i.setComponent(aTask.baseActivity); (...) 3) Launching the application when clicking on the button: intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK| Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED).addCategory(Intent.CATEGORY_LAUNCHER); monthis.startActivity(intent); ` What is wrong with this code? Should I do something different to get it? Thank a lot for any answer.

• adding new Input to jquery validationEngine form?

  - by Hailwood

  I have some fairly complex ajax logic etc going on in the onValidationComplete function for a form with jQuery Validation Engine. This is working perfect, but one thing is bothering me. in the form I have the ability to dynamically add inputs (add new row button). so my code structure wise looks like: var form = $('#myForm'); form.validationEngine('attach', {onValidationComplete:validationComplete}); $('#newInput').on('click', function(){ form.append('<input />'); form.validationEngine('detach'); form.validationEngine('attach', {onValidationComplete:validationComplete}); }); function validationComplete(form, status){/*all my logic here*/} What I don't like about it is that every time I add a new input I have to detach and then re-attach the validationEngine. Is there any way to just tell it to add the new input to it's list of inputs to validate?

• pyramid view redirection

  - by ascobol

  This question title may be slightly incorrect but I could not find a better one (yet). I'm trying to integrate Mozilla Persona (browserid) into a Pyramid application. The login process is: user can login on any page by clicking on the login button a popup then shows a login form when the users enters correct login/password, an ajax call is made by the popup to a pyramid view that checks users credentials, and calls pyramid remember function if the check succeeded the browserid javascript code then reloads the current page Now I want to handle the case of a new user subscribing to the web app and present a new view asking for a few more details (desired username, etc) Since the "remember" function is called by an ajax call from the popup, I cannot redirect the user the the "/newuser" page. So every view needs to redirect new users to the "/newuser" url whenever the remembered browserid has no corresponding user in the database. Is there a way to intercept user requests before calling a view to call the "new_user" view instead ? Or maybe my authentication approach is fundamentally incorrect and I should rely on another approach ?
