  • What is correct content-type for excel files?

    - by taw
    I want excel files on a website to open in Excel when clicked, not get saved on desktop, or get opened embedded in a browser etc. Now obviously it all depends on how everything is configured for each user, but what's the best Content-Type and other settings to achieve just that most of the time?

  • possible to auto zoom out if user's resolution < x ?

    - by Haroldo
    my site is aimed purely at the laptop market (dont ask why or argue!), all my users (or 95%+) we on a screen width of 1200+, netbooks are now taking off, with a resolution of 1024 wide. my site still looks great on a netbook if you zoom out once (ctrl-minus), but i don't want to rely on users knowing about ctrl-minus. what are my options besides redesign? I'm keen not to have zoom buttons on my page. is there a javascript zoomer outer?!!!

  • Is it possible to run a Java program inside a Flex application?

    - by Joshua
    I would like to be able to incorporate a simple game, written in Java as a component within a Flex Application. Am I crazy? Flex can display HTML, and SWF, it can also call JavaScript - but can I incorporate an applet somehow? I do NOT mean kludging it in as a sister component within a browser, but actually within the flex application itself, so that it could also run under Adobe Air, for instance.

  • Is the recent trend toward widescreen (16:9) computer monitors a plus or minus for programmers?

    - by DanM
    It's almost gotten to the point where you can't buy a conventional (4:3) monitor anymore. Pretty much everything is widescreen. This is fine for watching movies or TV, but is it good or bad for programming? My initial thoughts on the issue are that widescreens are a net negative for programmers. Here are some of the disadvantages I see: Poor space utiliziation One disadvantage of widescreens you can't argue with is that they offer poor space utilization for the amount of total pixels you get. For example, my Thinkpad, which I bought just before the widescreen craze, has a 15" monitor with a native resolution of 1600 x 1200. The newer 15.4" Thinkpads run at most 1680 x 1050. So (if you do the math) you get fewer pixels in a wider (but not shorter) package. With desktop monitors, you pay a price in terms of desk space used. Two 1680 x 1050 monitors will simply take up more of your desk than two 1600 x 1200 monitors (assuming equal dot pitch). More scrolling If you compare a 1680 x 1050 monitor to a 1600 x 1200 monitor, you get 80 extra pixels of width but 150 fewer pixels of height. The height reduction means you lose approximately 11 lines of code. That's less you can see on the screen at one time and more scrolling you have to do. This harms productivity, maybe not dramatically, but insidiously. Less room for wide panels Widescreens also mean you lose space for wide but short panels common in programming environments. If you use Visual Studio, for example, your code window will be that much shorter when viewing the Find Results, Task List, or Error List (all of which I use frequently). This isn't to say the 80 pixels of extra width you get with widescreen would never be useful, but I tend to keep my lines of code short, so seeing more lines would be more valuable to me than seeing fewer, longer lines. What do you think? Do you agree/disagree? Are you now using one or more widescreen monitors for development? What resolution are you running on each? Do you ever miss the height of the traditional 4:3 monitor? Would you complain if your monitors were one inch narrower but two inches taller?

  • Is there an open source UIView subclass for creating multiple, dynamic tabs in the iPhone (iPad) SDK

    - by smountcastle
    Is there an open source UIView component that supports multiple, dynamic tabbed views for the iPhone (iPad) SDK? I see several apps in the iPad App Store which utilize tabs, one such example is the Atomic Web Browser which provides a tabbed browsing experience (like Safari on the Mac or Firefox). Instead of reinventing this functionality, I'd like to reuse an existing component.

  • Extract new image dimensions from timthumb

    - by jonthoughtit
    I'm using timthumb to resize my images because it scales them nicely if I only enter one of the dimensions. However I want to know if it's possible to extract the new resized image's dimensions so that I can add that dynamically to the img tag attributes. I tried this with no luck: $fullpath = '/lib/timthumb.php?src='.$image.'&w=100'; $my_image = array_values(getimagesize($fullpath)); list($width, $height, $type, $attr) = $my_image; Any ideas?

  • JLabel not displaying all the characters even after dynamically changing font size

    - by wniroshan
    Hi all, I am trying to fit a sentence that changes often, in to a few jlabels. Widths of my 3 jlabels stay unchanged all the time. What I am doing is changing the font size so all the characters can fit with out non being out of the display range of the labels. What I do is call below code snippet when ever sentence is changed. Here is my code String sentence = "Some long sentence"; int SentenceLength = sentence.length(); int FontSize = 0; // sum of widths of the three labels int TotalLblLength=lbl_0ValueInWords.getWidth()+lbl_1ValueInWords.getWidth()+lbl_1ValueInWords.getWidth(); /*decide the font size so that all the characters can be displayed with out exceeding the display renge(horizontal) of the 3 labels Inconsolata -> monopace font font size == width of the font*2 (something I observed, not sure if this is true always) */ FontSize=(TotalLblLength/SentenceLength)*2; // max font size is 20 - based on label height FontSize=(FontSize>20)?20:FontSize; lbl_0ValueInWords.setFont(new java.awt.Font("Inconsolata", 0,FontSize)); lbl_1ValueInWords.setFont(new java.awt.Font("Inconsolata", 0,FontSize)); lbl_2ValueInWords.setFont(new java.awt.Font("Inconsolata", 0,FontSize)); int CharCount_lbl0 = width_lbl0 / (FontSize / 2); int CharCount_lbl1 = width_lbl1 / (FontSize / 2); int CharsCount_lbl2 = width_lbl2 / (FontSize / 2); /*Set texts of each label if sentence has more than the number of characters that can fit in the 1st label, excessive characters are moved to the 2nd label. same goes for the 2nd and 3rd labels*/ if (SentenceLength > CharCount_lbl0) { lbl_0ValueInWords.setText(sentence.substring(0, CharCount_lbl0)); if (SentenceLength > CharCount_lbl0 + CharCount_lbl1) { lbl_1ValueInWords.setText(sentence.substring(CharCount_lbl0, CharCount_lbl0 + CharCount_lbl1)); lbl_2ValueInWords.setText(sentence.substring(CharCount_lbl0 + CharCount_lbl1, SentenceLength)); } else { lbl_1ValueInWords.setText(sentence.substring(CharCount_lbl0, SentenceLength)); } } else { lbl_0ValueInWords.setText(sentence); } But even after resetting font size sometimes the last character goes out of the display range. I have removed margines from the jlabels that may cause this. This happens for random length sentences. I can solve the problem for the application by reducing label width used for the calculations(hopefully) Can anyone explain me the reason? Could be because of some defect in the fonts symmetry?

  • Should HTML be encoded before being persisted?

    - by Sir Psycho
    Should HTML be encoded before being stored in say, a database? Or is it normal practice to encode on its way out to the browser? Should all my text based field lengths be quadrupled in the database to allow for extra storage? Looking for best practice rather than a solid yes or no :-)

  • Is there a light and simple php framework that provides basic localization and/or internationalizati

    - by janoChen
    I would like a php framework that: Is simple and lightweight It work in shared hosting (free hosting) I'll be nice if it saves the preferred language using cookies (not necessary) I'll be nicer if it detects user's preferred language from the browser (not necessary) I want to build a page that displays 3 different languages. I came out with a mini localization framework but I think is kinda buggy. Any suggestions?

  • Cannot export a fusionchart with 'Embedding Charts Using <OBJECT>/<EMBED> Tags'

    - by zoom_pat277
    I am trying to export a fusion chart created using 'Embedding Charts Using / Tags'. Export works just perfect with the right click (on the chart) and chose a pdf to export.

  • Using font in site

    - by Misha Moroshko
    I know that I can use fonts like arial "for free". But what if I want to use not a standard font ? Is that something that a browser should support ? Where I can check, for example, which fonts Firefox 3.6.3 supports ? I would like, for example, to change the font of input text area.

  • CSS Z-Index with Gradient Background

    - by Jona
    I'm making a small webpage where the I would like the top banner with some text to remain on top, as such: HTML: <div id = "topBanner"> <h1>Some Text</h1> </div> CSS: #topBanner{ position:fixed; background-color: #CCCCCC; width: 100%; height:200px; top:0; left:0; z-index:900; background: -moz-linear-gradient(top, rgba(204,204,204,0.65) 0%, rgba(204,204,204,0.44) 32%, rgba(204,204,204,0.12) 82%, rgba(204,204,204,0) 100%); /* FF3.6+ */ background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(204,204,204,0.65)), color-stop(32%,rgba(204,204,204,0.44)), color-stop(82%,rgba(204,204,204,0.12)), color-stop(100%,rgba(204,204,204,0))); /* Chrome,Safari4+ */ background: -webkit-linear-gradient(top, rgba(204,204,204,0.65) 0%,rgba(204,204,204,0.44) 32%,rgba(204,204,204,0.12) 82%,rgba(204,204,204,0) 100%); /* Chrome10+,Safari5.1+ */ background: -o-linear-gradient(top, rgba(204,204,204,0.65) 0%,rgba(204,204,204,0.44) 32%,rgba(204,204,204,0.12) 82%,rgba(204,204,204,0) 100%); /* Opera 11.10+ */ background: -ms-linear-gradient(top, rgba(204,204,204,0.65) 0%,rgba(204,204,204,0.44) 32%,rgba(204,204,204,0.12) 82%,rgba(204,204,204,0) 100%); /* IE10+ */ background: linear-gradient(to bottom, rgba(204,204,204,0.65) 0%,rgba(204,204,204,0.44) 32%,rgba(204,204,204,0.12) 82%,rgba(204,204,204,0) 100%); /* W3C */ filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#a6cccccc', endColorstr='#00cccccc',GradientType=0 ); /* IE6-9 */ } /*WebPage Header*/ h1{ font-size:3em; color:blue; text-shadow:#CCCCCC 2px 2px 2px, #000 0 -1px 2px; position: absolute; width: 570px; left:50%; right:50%; line-height:20px; margin-left: -285px; z-index:999; } The z-index works fine, except that because I'm using a gradient any time I scroll down the elements behind the banner are still visible, albeit somewhat transparent. Is there any way to make them total invisible? i.e., what I'm trying to do is make it as though the banner is a solid color, even though it's a gradient. Thanks in advance for any help!

  • Android WVGA800 and 854

    - by Droidy
    Although my relativelayout looks very similar on WVGA800 and WVGA854 on the emulator, theres different spacing on some of the objects because I'm going off of marginleft or marginright. Since the 854 is a greater width, its pushing some objects differently. Is there any way I could target either one to adjust for the different margins?

  • ASP.NET - What happens when a HttpCookie expiration has been crossed

    - by user70192
    Hello, I am creating some cookies in my ASP.NET application. These cookies expire 10 minutes after they have been created. I follow the approach described on MSDN as shown here: http://msdn.microsoft.com/en-us/library/system.web.httpcookie.expires.aspx My question is, when a cookie "expires", what happens? Does the browser automatically delete the cookie? Is it our responsibility as developers to remove the cookies if they exist and have expired? Thank you,

  • Is this a legitimate implementation of a 'remember me' function for my web app?

    - by user246114
    Hi, I'm trying to add a "remember me" feature to my web app to let a user stay logged in between browser restarts. I think I got the bulk of it. I'm using google app engine for the backend which lets me use java servlets. Here is some pseudo-code to demo: public class MyServlet { public void handleRequest() { if (getThreadLocalRequest().getSession().getAttribute("user") != null) { // User already has session running for them. } else { // No session, but check if they chose 'remember me' during // their initial login, if so we can have them 'auto log in' // now. Cookie[] cookies = getThreadLocalRequest().getCookies(); if (cookies.find("rememberMePlz").exists()) { // The value of this cookie is the cookie id, which is a // unique string that is in no way based upon the user's // name/email/id, and is hard to randomly generate. String cookieid = cookies.find("rememberMePlz").value(); // Get the user object associated with this cookie id from // the data store, would probably be a two-step process like: // // select * from cookies where cookieid = 'cookieid'; // select * from users where userid = 'userid fetched from above select'; User user = DataStore.getUserByCookieId(cookieid); if (user != null) { // Start session for them. getThreadLocalRequest().getSession() .setAttribute("user", user); } else { // Either couldn't find a matching cookie with the // supplied id, or maybe we expired the cookie on // our side or blocked it. } } } } } // On first login, if user wanted us to remember them, we'd generate // an instance of this object for them in the data store. We send the // cookieid value down to the client and they persist it on their side // in the "rememberMePlz" cookie. public class CookieLong { private String mCookieId; private String mUserId; private long mExpirationDate; } Alright, this all makes sense. The only frightening thing is what happens if someone finds out the value of the cookie? A malicious individual could set that cookie in their browser and access my site, and essentially be logged in as the user associated with it! On the same note, I guess this is why the cookie ids must be difficult to randomly generate, because a malicious user doesn't have to steal someone's cookie - they could just randomly assign cookie values and start logging in as whichever user happens to be associated with that cookie, if any, right? Scary stuff, I feel like I should at least include the username in the client cookie such that when it presents itself to the server, I won't auto-login unless the username+cookieid match in the DataStore. Any comments would be great, I'm new to this and trying to figure out a best practice. I'm not writing a site which contains any sensitive personal information, but I'd like to minimize any potential for abuse all the same, Thanks

  • Web History: Early examples of collapsing and expanding content in an essay

    - by jes5199
    I vaguely remember that in the early days of the browser, one notion of what hypertext could be used for was a "zoom in" detail for academic essays: if you wanted a brief overview, you'd take the outermost level, and if you wanted to delve, you would click something and more sentences would appear. I know this sounds trivial and now, but in the mid-1990s it was thought-provoking. Has anyone seen any web fossils like this lying around, ideally still live on the web somewhere?
