• ASP.Net: Expiring a page when navigating back

  - by K2so

  Basically all pages on this site I am building cannot be accessed when the user clicks on "Back" (or with key control) in the browser, and the page should expire if one is trying to navigate back in history. I put into Global.asax::Application_BeginRequest Response.Cache.SetCacheability(HttpCacheability.NoCache) Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1)) Response.Cache.SetValidUntilExpires(False) Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches) Response.Cache.SetNoStore() This would clear out the cache and disallow going back to any pages when the user is logged out, but doesn't do the job while the user is logged in. I saw posts where people suggested using a javascript approach, by calling History.Forward(1) on the page. But I wouldn't like to do this, as it will require javascript enabled to work (which user can disable). Appreciate any suggestions.

• VBA - Prevent Excel 2007 from showing a defined names message box?

  - by John M

  I am working on a Excel 2007 workbook that will contain a macro to save the current sheet (a template) as a PDF file (no problem) a Excel 97-2003 file (problem) When saving the Excel file a messagebox appears asking about "Defined names of formulas in this workbook may display different values when they are recalculated...Do you want Excel to recalculate all formulas when this workbook is opened?". The user can then select Yes/No and then the file will save. How do I disable the messagebox from appearing? The default answer would be 'No'. My code for saving: Sub saveAs_97_2003_Workbook(tempFilePath As String, tempFileName As String) Dim Destwb As Workbook Dim SaveFormat As Long 'Remember the users setting SaveFormat = Application.DefaultSaveFormat 'Set it to the 97-2003 file format Application.DefaultSaveFormat = 56 ActiveSheet.Copy Set Destwb = ActiveWorkbook Destwb.CheckCompatibility = False With Destwb .SaveAs tempFilePath & tempFileName & ".xls", FileFormat:=56 .Close SaveChanges:=False End With 'Set DefaultSaveFormat back to the users setting Application.DefaultSaveFormat = SaveFormat End Sub

• Bootstrap jquery methods Magento's prototype lib

  - by user1722527

  Wonder if anyone has had this issue. I've integrated Bootstrap nicely into a Magento theme I'm building, all good. That is, until I try using the accordian functions. There seems to be an issue with the code finding the Prototype Libs Methods instead of jQuery's. I've tried the usual fixes, $ - jQuery and no conflict but it only works when I disable the prototype lib - which obviously is not good. Anyone out there come across this and can advise me on a work round? At the moment I'm resigned to using Scriptaculous for the accordian.

• How to deal with accelerators for disabled controls?

  - by sharptooth

  I have a dialog created from a template. It has controls listed in the template in the following order: some irrelevant controls a label with an accelerator (let's pretend it's Alt-A) an edit box OK and Cancel buttons Normally when I hit Alt-A the keybord focus is transferred to the edit box - just as needed. However I sometimes need to disable to edit box. If I hit Alt-A when the edit box is disabled the effect is that the OK button is pressed and that is definitely not what I want. I would prefer to have no action taken in this case. What could I do to workaround this?

• jQuery: Freezing/Disabling all events temporarily?

  - by Legend

  I have the following usecase: A div with some buttons When the user clicks on a button, a popup is shown and the background div is faded out to 0.5 opacity The problem is that when the popup comes in, the user is still able to click on the background buttons. At this point, I can remove the entire DIV temporarily but I don't want to do that. Is there anyway I can disable all the previously attached events and then add event handlers ONLY to the current popup? (I mean something like a close button should still work on a popup) Any suggestions?

• Prevent blank links (having javascript:;) from openening in new tab/window on middle click...?

  - by jayarjo

  There is a common practice of using <a></a> tags to markup beautiful buttons, with onlick and onhover style change, etc. Which looks and behaves great, on most part. Although there turned out to be a HUGE problem, which was not very obvious on start. The problem is that these beautiful "buttons" open new windows on middle click, either blank or with the same content as current one (depends on whether one uses # or javascript:; to disable href part). Now I've got JavaScript RIA with buttons all over it, opening new windows on middle click... Lame... At first I even couldn't understand why I get sometimes those blank pages in the browser. Since it's pretty established practice to use links in such manner, maybe there is any established way to deal with described problem?

• How to access device settings on a S60 symbian based mobile phone?

  - by TheRHCP

  Hello everyone, I recently bought a Sony Ericsson mobile phone which embeds Symbian S60 and I would like to add a missing feature myself. In fact I cannot actually disable Internet connection in an easy way when roaming, which cost me a lot of money last time I moved away ... So I would like to develop a little application that would just replace the actual Internet configuration with a fake configuration to avoid auto-connections. So what I would like to know is how can I access programmatically to my phone settings? I believe that this is possible but I do not really have a clue where to start. I know that Sony Ericsson provides a SDK to run Java applications on its customised JVM but Symbian is also providing a SDK to develop applications for S60 devices in many languages. The real questions is which SDK will provide an API able to access phone settings. This is not well documented so I am asking this question with the hope that someone here already had experience with development for Sony Ericsson/Symbian devices. Thanks.

• JQuery: Hover to show/hide individual object

  - by noe ruiz

  Basically I need to hover over an anchor to display the "data-meta" div. Works just fine but when there's multiple td and divs, one hover displays all of them. My question is how can I show/hide them individually? Code snippets below. <td> <a href="#">Item</a> <div class="data-meta"> <a href="#">Edit</a> | <a href="#">Disable</a> | <a href="#">Delete</a> </div> $(document).ready(function(){ $("td").hover( function () { $('.data-meta').show(); }, function () { $('.data-meta').hide(); }); });

• auto_inline - inadequate documentation

  - by Mick

  I want to disable inlining for a particular function. What the compiler does for everything else should be as specified in the project properties. I found a page on a forum which suggested the following: #pragma auto_inline(off) void func() { } #pragma auto_inline() The author suggested that calling auto_inline() with no arguments will set the compiler to revert to doing whatever the default action was before the call to auto_inline(off). Can anyone confirm that this works for visual studio 2008? I ask because the VS2008 documentation makes no mention at all of what happens if you call this function with no arguments.

• Rails: Link changes one attribute and then goes back

  - by James

  Rails newbie here. I have a list of items which can have a status represented by an integer (right now its just 1=active 0=inactive). What I want is next to each item a link to change the status of that item. So it might look like this: A nice item - Enable Another pretty item - Disable I can't think of how to make the link work. I just want a user to click the link and then the page refreshes and the item get updated. This doesn't work: <%= link_to "Enable", :controller => "items", :action => "update", :status => 1 %>

• Prevent double submission of forms in jQuery

  - by Adam

  I have an form that takes a little while for the server to process. I need to ensure that the user waits and does not attempt to resubmit the form by clicking the button again. I tried using the following jQuery code: <script type="text/javascript"> $(document).ready(function(){ $("form#my_form").submit(function(){ $('input').attr('disabled','disabled'); $('a').attr('disabled','disabled'); return true; }) }); </script> When I try this in Firefox everything gets disabled but the form is not submitted with any of the POST data it is supposed to include. I can't use jQuery to submit the form because I need the button to be submitted with the form as there are multiple submit buttons and I determine which was used by which one's value is included in the POST. I need the form to be submitted as it usually is and I need to disable everything right after that happens. Thanks!

• WPF Custom Navigation Buttons and calling one page from another

  - by Jeff

  I have a window which contains a Frame which references a 'home' page that has buttons on it. When a button is clicked I want another page to show depending on which button was pressed. I attempted to use NavigationService.Navigate('mynextpage.xaml') and that works however, I want to use a customized navigation panel. I call this.ShowsNavigationUI = false; on my 'home' page but the bar still shows. Is there a way to accomplish what I am trying to do? My page with the frame is a window so I do not know how to disable the Navigation bar there where I guess it is coming from. Further testing shows that the ShowsNavigationUI property is false yet the nav bar shows itself in the parent window once there is a second page to go to (showing the 'home' page in the history. TIA

• Trigger Event after values have been commited for validation purposes

  - by www.jefferyfernandez.id.au

  I have a Flex component with a form and on creationComplete, I load some data onto the form textInputs. After the Form TextInputs have got their values, I want to trigger an event so the Parent of the component can validate the values on the TextInputs and based on the validation results, I perform some enable/disable of other interfaces. I have the following dispatch code: this.dispatchEvent(new PersonalDetailsEvent(PersonalDetailsEvent.LOADED_DATA_EVENT)); The event is dispatched and is captured by the parent. But upon performing the validation, some TextInputs always fail the validation. I thought it could be because of a race condition and so I used callLater() with same results. So in the end I am now using a timer to dispatch the event which is not ideal. Does anyone have a solution to this problem. It is really annoying that a timer needs to be used for this scenario.

• Preventing decompilation of C# application

  - by Kalpak

  Hi, We are planning to develop a client server application using C# and MySQL. We plan to sell the product on the shelf like any other software utility. We are worried about the decompilation of our product which does have some sort of edge over our competitors in terms of usability and bundled functionality. How can we prevent our software from decompilation, so the business logic of the product remains intact? We have heard about Reflector and other decompilers which makes our code very much vulnerable for copying. Our customer base is not Corporates by medical practitioners who themselves may not do it but our competitors may want to copy/disable licensing so value of our software goes down. Any suggestion to prevent this is most welcome. regards.. Obelisk

• test php disabled caching

  - by user1691389

  My site had a problem in that certain browsers (especially opera and gecko) were "over-caching" (caching far too much for my taste). I've just added the following PHP snippet to hopefully disable caching in all browsers: <?php header("Expires: Tue, 01 Jan 2000 00:00:00 GMT"); header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0"); header("Cache-Control: post-check=0, pre-check=0", false); header("Pragma: no-cache"); ?> Question: How would you test this out, to make sure it actually works?

• How do I run Eclipse using Oracle's new 1.7 JDK for the Mac?

  - by sanity

  I'm trying to get the new 1.7 JDK working with Eclipse (this is Oracle's official release). I don't mean just pointing Eclipse to it so you can use it in projects, this works fine, but actually making Eclipse run using the 1.7 JVM. I've moved the new JVM to the top of the list in Java Preferences, but Eclipse still starts with 1.6. If I disable 1.6 in Java Preferences I get a dialog immediately after I double-click on Eclipse saying "Failed to create the Java Virtual Machine". edit: I added the following to my eclipse.ini just before the -vmargs: -vm /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home/bin/java Yet in the Eclipse installation details dialog I still see: java.runtime.version=1.6.0_31-b04-415-11M3646 edit 2: here are the contents of my eclipse.ini file: https://gist.github.com/2512578

• Hide Adsense on localhost

  - by collimarco

  I have a site built in Ruby On Rails which has many ads in different templates and views. It is hard to actualy remove each ad between tests and deployments. I don't know whether Google approves many impressions (even if without clicks) on localhost. How do you deal with this issue? Maybe it is a good solution to set a variable/constant available everywere to enable/disable ads easily. Do you think it is a good solution? If so, how do I declare a global variable for views?

• How to prevent robots from automatically filling up a form?

  - by sombe

  I'm trying to come up with a good enough anti-spamming mechanism to prevent automatically generated input. I've read that techniques like captcha, 1+1=? stuff work well, but they also present an extra step impeding the free quick use of the application. (I'm not looking for anything like that please). I've tried setting some hidden fields in all of my forms, with display: none; However, I'm almost certain a robot (which is essentially a program) can be configured to trace that form field id and simply not fill it. Do you implement/know of a good anti automatic-form-filling-robots method? Is there something that can be done seamlessly with HTML AND/OR server side processing, and be (almost) foolproof? (and please no JS, one could simply disable it, and there goes my anti-spam method). Btw I'm trying not to rely on sessions for this (like, counting how many times a button is clicked to prevent overloads).

• CakePHP Form Helper - Show error class, but not error message

  - by Jeremy Penrod

  I'm attempting to customize the error output on the CakePHP 2.0 form helper. Currently, the form renders error messages below the input and applies an 'error' class to the input's label. I have found that I can either disable error reporting altogether for an input, or output the error class and message. I would like the error class to be applied to the label of the offending inputs WITHOUT any message below. How do you turn off the error message outputting for a form, BUT still apply error classes to offending labels?

• 16 millisecond quantization when sending/receivingtcp packets

  - by MKZ

  Hi, I have a C++ application running on windows xp 32 system sending and receiving short tcp/ip packets. Measuring (accurately) the arrival time I see a quantization of the arrival time to 16 millisecond time units. (Meaning all packets arriving are at (16 )xN milliseconds separated from each other) To avoid packet aggregation I tried to disable the NAGLE algorithm by setting the IPPROTO_TCP option to TCP_NODELAY in the socket variables but it did not help I suspect that the problem is related to the windows schedular which also have a 16 millisecond clock.. Any idea of a solution to this problem ? Thanks

• Handling missing data

  - by soppotare

  Say I have a simple helpdesk application which logs calls made by users. I would typically have such fields in a table relating to the call e.g. CallID, Description, CustomerID etc. I Would also have a table of customers including CustomerID, Username, Password, FullName etc. Now when a user is deleted from the customers table then the inner join between the calls table and the users table to find out historically which user logged a call would produce no results. How do people usually deal with this? Have seperate customer and useraccount tables Just disable the accounts so the data is still available Record the customers name in the calls table as a seperate field. or any other methods / suggestions?

• Disabling identity (auto-incrementing) on integer primary key using code first

  - by gw0

  I am using code first approach in a ASP.NET MVC 3 application and all integer primary keys in models (public int Id { get; set; }) are by default configured as an identity with auto-incrementing. How to disable this and enable a way to manually enter the integer for the primary key? The actual situation is that the Id integers have a special meaning and I would therefore like to have them choosable at creation and later editable. It would be ideal if in case the integer is not given at creation time it is auto-incremented, else the specified value is used. But editable primary fields is my primary need. Is there any way to do this elegantly in ASP.NET MVC 3?

• How does youtube enable ascii videos?

  - by acidzombie24

  Just by messing around a little it seems that the video stream is not ascii. i tested by downloading the stream. It would be insane if it was. Theres so many videos. So that couldnt be it. Youtube seems to not work with javascript disable (not counting mobile if true). How is it being done? is it javascript magic? is the SWF running the video through a filter in realtime? (I doubt its a native filter so how is the filter compiled) its really cool. I cant imagine how this is running realtime yet it is!
