  • Google Chrome does not honor cache-policy in page header if the page is displayed in a FRAME

    - by Tim
    No matter what I do: <meta http-equiv="Cache-Control" content="no-cache" /> <meta http-equiv="Expires" content="Fri, 30 Apr 2010 11:12:01 GMT" /> <meta http-equiv="Expires" content="0" /> <HTTP-EQUIV="PRAGMA" CONTENT="NO-STORE" /> Google Chrome does not reload any page according to the page's internal cache policy if the page is displayed in a frame. It is as though the meta tags are not even there. Google Chrome seems to be ignoring these tags. Since I've gotten answers to this question on other forums where the person responding has ignored the operative condition, I will repeat it: this behavior occurs when the page is displayed in a frame. I was using the latest released version and have since upgraded to 5.0.375.29 beta but the behavior is the same in both versions. Would someone please care to confirm one way or another the behavior you are seeing with framesets and the caching/expiration policies given in meta tags? Thanks

  • using CSS to center FLOATED input elements wrapped in a DIV

    - by Tim
    There's no shortage of questions and answers about centering but I've not been able to get it to work given my specific circumstances, which involve floating. I want to center a container DIV that contains three floated input elements (split-button, text, checkbox), so that when my page is resized wider, they go from this: ||.....[ ][v] [ ] [ ] label .....|| to this ||......................[ ][v] [ ] [ ] label.......................|| They float fine, but when the page is made wider, they stay to the left: ||.....[ ][v] [ ] [ ] label .......................................|| If I remove the float so that the input elements are stacked rather than side-by-side: [ ][v] [ ] [ ] label then they DO center correctly when the page is resized. SO it is the float being applied to the elements of the DIV#hbox inside the container that is messing up the centering. Is what I want to do impossible because of the way float is designed to work? Here is my DOCTYPE, and the markup does validate at w3c: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> Here is my markup: <div id="term1-container"> <div class="hbox"> <div> <button id="operator1" class="operator-split-button">equals</button> <button id="operator1drop">show all operators</button> </div> <div><input type="text" id="term1"></input></div> <div><input type="checkbox" id="meta2"></input><label for="meta2" class="tinylabel">meta</label></div> </div> </div> And here's the (not-working) CSS: #term1-container {text-align: center} .hbox {margin: 0 auto;} .hbox div {float:left; } I have also tried applying display: inline-block to the floated button, text-input, and checkbox; and even though I think it applies only to text, I've also tried applying white-space: nowrap to the #term1-container DIV, based on posts I've seen here on SO. And just to be a little more complete, here's the jQuery that creates the split-button: $(".operator-split-button").button().click( function() { alert( "foo" ); }).next().button( { text: false, icons: { primary: "ui-icon-triangle-1-s" } }).click( function(){positionOperatorsMenu();} ) })

  • Russian time zone changes

    - by Tim Post
    As many of you know, Russia has eleven time zones, and has (or will) cut two of them. It is possible that they may end daylight savings time altogether. Does anyone know if they have cut two time zones, and if daylight savings is now a thing of the past? If so, does daylight savings end in all time zones, or just some? I maintain some software that may need to be patched and can't find two news sites that agree on if they have, or have not implemented these changes.

  • How can I perform a reverse string search in Excel without using VBA?

    - by e.James
    I have an Excel spreadsheet containing a list of strings. Each string is made up of several words, but the number of words in each string is different. Using built in Excel functions (no VBA), is there a way to isolate the last word in each string? Examples: Are you classified as human? - human? Negative, I am a meat popsicle - popsicle Aziz! Light! - Light!

  • Monitor file in Java on Linux 64bits

    - by Tim
    I'd like to be notified when a file has been created, deleted or changed, but not using polling mechanism. I have surveyed related Java API that can use.(EX:JNotify, JPathWatch and JXFileWatcher) Those APIs provide file monitor by using native component on OS. But I met the same problem is that they can't run on Linux 64bits, because native component in those APIs donen't support Linux 64bits, and this confused me for a long time. I also know that there'll be a WatchService API as part of NIO2 in JDK7, but JDK7 has not released yet. So, can any one suggest me a better solution? Very Thanks.

  • iPhoneOS Core Data migration: moving something from an entity into a file

    - by Tim Sullivan
    I have a scenario where I'm moving the contents of a blob stored in a core data entity into a file. I need a way to export that data during a migration, where I know the entity that's being converted and save the blob to a file, writing the location of that file into the converted entity's appropriate attribute. I can't seem to find a way to do this. The docs regarding the Three Stage Migration seem to indicate what can be done, but I'm not sure where to define things, or what exactly to define.

  • NSNotification postNotificationName in AppDelegate but NSNotificationCenter in ViewController?

    - by James Testa
    I can't get the selector method, receiveChatText, in the NSNotificationCenter to execute and I am wondering if the problem is because the NSNotification postNotificationName is in AppDelegate.m but NSNotificationCenter is in ViewController.m? I.E. can the postNotificationName know that the NSNotificationCenter is in another viewController file or is that something I need to tell it? In a viewController.m I have -(id)init { self = [super init]; if(self){ [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(receiveChatText:) name:ChatMessageReceived object:nil]; return self; } - (void)receiveChatText:(NSNotification *)note { NSLog(@"received chat text"); } and in the top level AppDelegate.m file I have the following: -(void) didReceiveMessage { [[NSNotificationCenter defaultCenter] postNotificationName:ChatMessageReceived object:nil userInfo:nil]; } Any ideas what could stop receiveChatText from being executed when didReceiveMessage is called?

  • Visual Studio breaks, and steps, but sometimes steps out

    - by James Wilkins
    Something very odd is going on. It's been going on for some time, but I've just ignored it up to now. I have both a Silverlight and WCF service in my solution, which shares .CS file between them (one project has a link to the file, which exists in the other project). While debugging the Silverlight app, pressing the F10 key steps through code as normal, and when I get to a method call which exists in the shared file (between the projects), and Press F11, it simply skips the method instead of stepping into it (and yes, the "Just My Code" option is not checked). If I put a breakpoint in the method I'm trying to get into, it works fine (as in the debugger will break on the line), but as soon as I step (F10) it exits the method (and with F11 [step into] also). Ok, on first thought, you might think it's to do with the link, but no, it isn't. I tried removing the link and using a copy instead, but the same thing happens. And no, it's not the debug symbols, I looked into that already. The method I'm trying to step through is static, and is in a non-static partial class, in a file shared by both projects. My guess: The same types and static methods exist in the WCF and Silverlight ... would the debugger get confused?

  • Should I Use Anchor, Button Or Form Submit For "Follow" Feature In Rails

    - by James
    I am developing an application in Rails 3 using a nosql database. I am trying to add a "Follow" feature similar to twitter or github. In terms of markup, I have determined that there are three ways to do this. 1) Use a regular anchor. (Github Uses This Method) <a href="/users/follow?target=Joe">Follow</a> 2) Use a button. (Twitter Uses This Method) <button href="/friendships/create/">Follow</button> 3) Use a form with a submit button. (Has some advantages for me, but I haven't see anyone do it yet.) <form method="post" id="connection_new" class="connection_new" action="/users/follow"> <input type="hidden" value="60d7b563355243796dd8496e17d36329" name="target" id="target"> <input type="submit" value="Follow" name="commit" id="connection_submit"> </form> Since I want to store the user_id in the database and not the username, options 1 and 2 will force me to do a database query to get the actual user_id, whereas option 3 will allow me to store the user_id in a hidden form field so that I don't have to do any database lookups. I can just get the id from the params hash on form submission. I have successfully got each of these methods working, but I would like to know what is the best way to do this. Which way is more semantic, secure, better for spiders, etc...? Is there a reason both twitter and github don't use forms to do this? Any guidance would be appreciated. I am leaning towards using the form method since then I don't have to query the db to get the id of the user, but I am worried that there must be a reason the big guys are just using anchors or buttons for this. I am a newb so go easy on me if I am totally missing something. Thanks!

  • How Do I Prevent Rails From Treating Edit Fields_For Differently From New Fields_For

    - by James
    I am using rails3 beta3 and couchdb via couchrest. I am not using active record. I want to add multiple "Sections" to a "Guide" and add and remove sections dynamically via a little javascript. I have looked at all the screencasts by Ryan Bates and they have helped immensely. The only difference is that I want to save all the sections as an array of sections instead of individual sections. Basically like this: "sections" => [{"title" => "Foo1", "content" => "Bar1"}, {"title" => "Foo2", "content" => "Bar2"}] So, basically I need the params hash to look like that when the form is submitted. When I create my form I am doing the following: <%= form_for @guide, :url => { :action => "create" } do |f| %> <%= render :partial => 'section', :collection => @guide.sections %> <%= f.submit "Save" %> <% end %> And my section partial looks like this: <%= fields_for "sections[]", section do |guide_section_form| %> <%= guide_section_form.text_field :section_title %> <%= guide_section_form.text_area :content, :rows => 3 %> <% end %> Ok, so when I create the guide with sections, it is working perfectly as I would like. The params hash is giving me a sections array just like I would want. The problem comes when I want edit guide/sections and save them again because rails is inserting the id of the guide in the id and name of each form field, which is screwing up the params hash on form submission. Just to be clear, here is the raw form output for a new resource: <input type="text" size="30" name="sections[][section_title]" id="sections__section_title"> <textarea rows="3" name="sections[][content]" id="sections__content" cols="40"></textarea> And here is what it looks like when editing an existing resource: <input type="text" value="Foo1" size="30" name="sections[cd2f2759895b5ae6cb7946def0b321f1][section_title]" id="sections_cd2f2759895b5ae6cb7946def0b321f1_section_title"> <textarea rows="3" name="sections[cd2f2759895b5ae6cb7946def0b321f1][content]" id="sections_cd2f2759895b5ae6cb7946def0b321f1_content" cols="40">Bar1</textarea> How do I force rails to always use the new resource behavior and not automatically add the id to the name and value. Do I have to create a custom form builder? Is there some other trick I can do to prevent rails from putting the id of the guide in there? I have tried a bunch of stuff and nothing is working. Thanks in advance!

  • Python: For loop problem

    - by James
    I have a PSP page with html embedded. I need to place another for loop so i can insert another %s next to background-color: which will instert a appropriate colour to colour in the html table. For example i need to insert for z in colours so it can loop over the colours list and insert the correct colour. Where ever i try to insert the for loop it doesnt seem to work it most commonly colours each cell in the table 60 times then moves onto the next cell and repeats itself and crashes my web browser. The colours are held in a table called colours. code below: <table> <% s = ''.join(aa[i] for i in table if i in aa) for i in range(0, len(s), 60): req.write('<tr><td><TT>%04d</td>' % (i+1)); for k in s[i:i+60]: req.write('<TT><td><TT><font style="background-color:">%s<font></td>' % (k)); req.write('</TT></tr>') #end %> </table>

  • How can one prevent page breaks between Tables in SQL Reporting Services 2005?

    - by James
    I've been developing an SSRS 2005 report (a form letter) that contains two tables. The first "table" uses DataSet "A" to populate address fields on letterhead. The second table uses DataSet "B" to display a basic list of records that pertain to the addressed party. Even though the two tables are within the same page and all PageBreak* properties are set to "False", SSRS renders the report as two pages. How can I force both tables to render in series, without any forced page breaks?

  • What is the proper way to use a Logger in a Serializable Java class?

    - by Tim Visher
    I have the following (doctored) class in a system I'm working on and Findbugs is generating a SE_BAD_FIELD warning and I'm trying to understand why it would say that before I fix it in the way that I thought I would. The reason I'm confused is because the description would seem to indicate that I had used no other non-serializable instance fields in the class but bar.model.Foo is also not serializable and used in the exact same way (as far as I can tell) but Findbugs generates no warning for it. import bar.model.Foo; import java.io.File; import java.io.Serializable; import java.util.List; import org.slf4j.Logger; import org.slf4j.LoggerFactory; public class Demo implements Serializable { private final Logger logger = LoggerFactory.getLogger(this.getClass()); private final File file; private final List<Foo> originalFoos; private Integer count; private int primitive = 0; public Demo() { for (Foo foo : originalFoos) { this.logger.debug(...); } } ... } My initial blush at a solution is to get a logger reference from the factory right as I use it: public DispositionFile() { Logger logger = LoggerFactory.getLogger(this.getClass()); for (Foo foo : originalFoos) { this.logger.debug(...); } } That doesn't seem particularly efficient, though. Thoughts?

  • Finding the index of a list item in jQuery

    - by Tim Piele
    I have an unordered list of eight items. On page load the first five <li> have default thumbnail images in them and the 6th one has a 1px by 1px placeholder image with the ID of $('#last'). When a user inserts a new image it replaces the 'src' of $('#last') with their new image. It's not the most efficient way but it works. <ul> <li><img src="img1.png" /></li> <li><img src="img2.png" /></li> <li><img src="img3.png" /></li> <li><img src="img4.png" /></li> <li><img src="img5.png" /></li> <li><img src="1px.png" id="last"/></li> <li></li> <li></li> </ul> When the user adds a new image the ID of $('#last') is removed and I use each() to find the next empty <li> and insert the 1px by 1px image in it, with an ID of $('#last') so it is ready for the next image upload. At this point I need to get the index() of the <li> that now has the 1px by 1px image in it, whose ID is $('#last'), so that I can store the index in the session, so when a user comes back to the page the $('#last') ID is still set and ready to accept another image. How do I get the index of the <li> with that image in it, since it was set after page load? Is there a way to use delegate() or on() to get it? i.e. how do I get the index of an element that was set after page load?

  • Why does TrimStart trims a char more when asked to trim "PRN.NUL" ?

    - by James
    Here is the code: namespace TrimTest { class Program { static void Main(string[] args) { string ToTrim = "PRN.NUL"; Console.WriteLine(ToTrim); string Trimmed = ToTrim.TrimStart("PRN.".ToCharArray()); Console.WriteLine(Trimmed); ToTrim = "PRN.AUX"; Console.WriteLine(ToTrim); Trimmed = ToTrim.TrimStart("PRN.".ToCharArray()); Console.WriteLine(Trimmed); ToTrim = "AUX.NUL"; Console.WriteLine(ToTrim); Trimmed = ToTrim.TrimStart("AUX.".ToCharArray()); Console.WriteLine(Trimmed); } } } The output is like this: PRN.NUL UL PRN.AUX AUX AUX.NUL NUL As you can see, the TrimStart took out the N from NUL. But it doesn't do that for other strings even if it started with PRN. I tried with .NET Framework 3.5 and 4.0 and the results are same. Are there any explanation on what causes this behavior?

  • How can I get a rails server to use the same databse that cucumber uses during a test?

    - by James
    The cucumber test first makes an entry in the database and posts a form to a second server. This second server does some processing in background and then hits the first app (where the test is being run) with some data that the cucumber test needs to know about. I've tried running the main server via script/server and script/server -e test while the cucumber test is running, but I can't seem to force the server to use the same database that cucumber is using when it runs its step definitions. That is, when the second server pushes some data to a controller in the main server, the main server doesn't know about any entries that cucumber has made in the database. How can I get cucumber and the main server to use the same database?

  • Is there a visual guide to the UIKit components?

    - by Tim Büthe
    My Problem is this, I want to add some component to my App I saw in some other App. Everytime I wnat to do this, I start googling around for the name. It took me some time to find the name of UIActionSheet. Now I'm looking for that transparent overlay that appears when you turn the volume up and down. So, is there a good visual guide to the UIKit components? As an example, see the visual guide to swing components or this visual guide which is way to short/incomplete. And secondly, what's the name of the component I'm looking for?

  • GNU Make - Dependencies on non program code

    - by Tim Post
    A requirement for a program I am writing is that it must be able to trust a configuration file. To accomplish this, I am using several kinds of hashing algorithms to generate a hash of the file at compile time, this produces a header with the hashes as constants. Dependencies for this are pretty straight forward, my program depends on config_hash.h, which has a target that produces it. The makefile looks something like this : config_hash.h: $(SH) genhash config/config_file.cfg > $(srcdir)/config_hash.h $(PROGRAM): config_hash.h $(PROGRAM_DEPS) $(CC) ... ... ... I'm using the -M option to gcc, which is great for dealing with dependencies. If my header changes, my program is rebuilt. My problem is, I need to be able to tell if the config file has changed, so that config_hash.h is re-generated. I'm not quite sure how explain that kind of dependency to GNU make. I've tried listing config/config_file.cfg as a dependency for config_hash.h, and providing a .PHONY target for config_file.cfg without success. Obviously, I can't rely on the -M switch to gcc to help me here, since the config file is not a part of any object code. Any suggestions? Unfortunately, I can't post much of the Makefile, or I would have just posted the whole thing.
