  • Condition in ASP Repeater

    - by Abdel Olakara
    Hi all, I am trying to put a condition into my ASP repeater tag. I have a table being created and one of the td items is a link. The problem is I need to create a link upon checking the value in one the variable that is in the repeater container. Here is my code: <td><%#((VWApp.Code.TrackDM)Container.DataItem).CdNo%></td> <td><%#((VWApp.Code.TrackDM)Container.DataItem).ShippingNo%></td> Now i need to check the value of ShippingNo and rather than displaying it need to display a link. i tried to write an if condition like this: if(((VWApp.Code.TrackDM)Container.DataItem).ShippingNo. .. ) { // do processing and generate a link that needs to displayed } But i get error when trying to do this. Can anybody guide me to the right way of doing this? Any ideas and suggests are highly appreciated.

  • How can I only allow certain filetypes on upload in php?

    - by Chris
    I'm making a page where the user upload a file. I want an if statement to create an $error variable if the file type is anything other jpg, gif, and pdf. Here's my code: $file_type = $_FILES['foreign_character_upload']['type']; //returns the mimetype if(/*$file_type is anything other than jpg, gif, or pdf*/) { $error_message = 'Only jpg, gif, and pdf files are allowed.'; $error = 'yes'; } I'm having difficulty structuring the if statement. How would I say that?

  • ASP.Net Session data lost between pages

    - by Ananth
    Hi, i came across a weird behavior today w/ my web application. When I navigate from a page to another, I lose one particular session variable data. I'm able to launch the app in firefox and able to see that the session data is not lost. I use Response.Redirect(page2, false) to redirect to another page. Below code was used to track session variables System.IO.StreamWriter sw = new System.IO.StreamWriter(@"c:\test.txt", true); for (int i = 0; i < Session.Count; i++) { sw.WriteLine(Session.Keys[i] + " " + Session.Contents[i]); } sw.Close(); Can anyone help me in this? Any help is appreciated. ~/Ananth

  • Using the Facebook Graph APIs PHP library

    - by briggins5
    I am using the PHP library for the Graph API (http://github.com/facebook/php-sdk) but am a bit confused about how it is all working (or not). I just want to authenticate the user and get the user ID back. What I really want to know is what to do once the user has logged in to Facebook and returned to my site. There is data called 'session' in the URL. Does this need to be stored in order to continually get the user ID? It is really not apparent, to me, from the samples or (lack of) documentation. Also, would it be easier to just cut out the PHP library altogether and just handle the reponse myself, storing it in a session variable. If i were to do this, what is the best method of getting/extracting the current users ID?

  • Modify headers in Pylons using Middleware

    - by Anders
    Hi all, I'm trying to modify a header using Middleware in Pylons to make my application RESTful, basically, if the user request "application/json" via GET that is what he get back. The question I have is, the variable headers is basically a long list. Looking something like this: [('Content-Type', 'text/html; charset=utf-8'), ('Pragma', 'no-cache'), ('Cache-Control', 'no-cache'), ('Content-Length','20'), ('Content-Encoding', 'gzip')] Now, I'm looking to just modify the value based on the request - but are these positions fixed? Will 'Content-Type' always be position headers[0][0]? Best Regards, Anders

  • OAuth iPhone client, problems with HTTP_AUTHORIZATION

    - by Rich
    Hi, I've been trying to implement OAuth in my iPhone app. However I have hit a problem. I have two servers, a local web server which is on my machine at home, I use this for testing. The machine is IIS 7 running PHP 5.08. Everything works fine on this server. However my live (web server) is running Apache and PHP 5.12. The problem is when I try to request a RequestToken the HTTP_AUTHORIZATION variable isn't posted to the web server, so I get an error returned from the server saying 'Invaild Consumer Key'. There is clearly a problem with the way the server is setup (as the code works on my local server). The code I am using is from this walkthrough http://code.google.com/p/oauthconsumer/wiki/UsingOAuthConsumer I have tried dumping the PHP headers and indeed HTTP_AUTHORIZATION is missing. Can anyone tell me how to fix this? (as it's driving me mad :)) Thanks Rich

Any Idea?

  • Empty accessors do matter? Regarding value types and their modification

    - by Petr
    Hi, I have following code that does not work due to "a" being a value typed. But I thought it would not work even without accessors, but it did: class Program { a _a //with accessors it WONT compile { get; set; } static void Main(string[] args) { Program p = new Program(); p._a.X = 5; //when both accessors are deleted, compiler does not //complain about _a.X not being as variable } } struct a { public int X; } It does not work as "a" is struct. But when I delete accessors from "_a" instance, it works. I do not understand why. Thanks

  • Implementing Brainf*ck loops in an interpreter

    - by sub
    I want to build a Brainf*ck (Damn that name) interpreter in my freshly created programming language to prove it's turing-completeness. Now, everything is clear so far (<+-,.) - except one thing: The loops ([]). I assume that you know the (extremely hard) BF syntax from here on: How do I implement the BF loops in my interpreter? How could the pseudocode look like? What should I do when the interpreter reaches a loop beginning ([) or a loop end (])? Checking if the loop should continue or stop is not the problem (current cell==0), but: When and where do I have to check? How to know where the loop beginning is located? How to handle nested loops? As loops can be nested I suppose that I can't just use a variable containing the starting position of the current loop. I've seen very small BF interpreters implemented in various languages, I wonder how they managed to get the loops working but can't figure it out.

  • (partial apply str) and apply-str in clojure's ->

    - by Jason Baker
    If I do the following: user=> (-> ["1" "2"] (partial apply str)) #<core$partial__5034$fn__5040 clojure.core$partial__5034$fn__5040@d4dd758> ...I get a partial function back. However, if I bind it to a variable: user=> (def apply-str (partial apply str)) #'user/apply-str user=> (-> ["1" "2" "3"] apply-str) "123" ...the code works as I intended it. I would assume that they are the same thing, but apparently that isn't the case. Can someone explain why this is to me?

  • Using readfile() with remote URL and SSL

    - by ColmF
    I have a php-based website that uses SSL and requires a a user to login before accessing any page. I would like to allow access to this site from another domain, so that the functionality remains the same, but the look, feel and domain changes for the user (with the added advantage that I have to maintain only one version of the code). Having done some reading, I'm using readfile() function calls in php files on the secondary server to corresponding files on the primary server. For example, the login.php on the primary server is accessed from the secondary server by a file called login.php containing readfile("http://www.primarydomain.com/login.php") (and nothing else). Now the problem - I can't even login! The login page appears fine when called initially, but when login user and pwd are entered and submitted, it's as if the remote server doesn't see the $_SERVER['REQUEST_METHOD'] variable that triggers form processing and just loads as an empty form. Any ideas what I'm doing wrong or what configuation I might need to change? Thanks!

  • Ho to get PHP setrawcookie value back?

    - by user250343
    The IETF recommends to use base64 encoding for binary cookie values. http://tools.ietf.org/html/draft-ietf-httpstate-cookie-07 So I use setrawcookie(..) but I don't know what variable to use to get the cookie back because $_COOKIE[..] still uses the URL decoding that matches setcookie(..). This replaces "+" with " " in the output. <?php var_dump($_COOKIE['TEST']); $binary_string = ""; for($index = 0; $index < 256; $index++){ $binary_string .= chr($index); } $encoded_data = base64_encode($binary_string); var_dump($encoded_data); $cookie_set = setrawcookie('TEST', $encoded_data, time() + 3600); ?

  • Django comparing model instances for equality

    - by orokusaki
    I understand that, with a singleton situation, you can perform such an operation as: spam == eggs and if spam and eggs are instances of the same class with all the same attribute values, it will return True. In a Django model, this is natural because two separate instances of a model won't ever be the same unless they have the same .pk value. The problem with this is that if a reference to an instance has attributes that have been updated by middleware somewhere along the way and it hasn't been saved, and you're trying to it to another variable holding a reference to an instance of the same model, it will return False of course because they have different values for some of the attributes. Obviously I don't need something like a singleton , but I'm wondering if there some official Djangonic (ha, a new word) method for checking this, or if I should simply check that the .pk value is the same with: spam.pk == eggs.pk I'm sorry if this was a huge waste of time, but it just seems like there might be a method for doing this, and something I'm missing that I'll regret down the road if I don't find it.

  • create a simple pdf report from html

    - by opensas
    I'm looking for a way to generate pdf files from html In order to make simple tabular reports I would need the following features table rendering variable page size repeating headers / footers on every page calculated page number / total page css support would be nice I know there have been many similar questions in stackoverflow, but I don't know if there's a product that supports the aforementioned features... Ideally, the source would be a plain and simple well built html with css, (I'm building the html files, so I can adapt to the products needs, that is, it won't have to render every piece of html crap you can throw at a browser) and with some custom tags to configure headings, footer, page size, etc... then I would run a command line to convert it from html to pdf. I think http://www.allcolor.org/YaHPConverter/ does something like that

  • Unable to view values of variables while debugging

    - by RexM
    I'm trying to debug portions of the current application I'm working on, however when I try and check the value of a property/variable I get the error: Cannot evaluate expression because a thread is stopped at a point where garbage collection is impossible, possibly because the code is optimized. This is just a regular ASP.NET project. In some portions of the application I can view the properties and variables perfectly fine. I haven't figured out what's different about the blocks of code that I can and can not see the values of the variables in.

  • VB.net Edit-And-Continue: ignore "unable to apply this change while debugging"

    - by FastAl
    When using VB.Net (2008) and paused in debugging, Edit-And-Continue is a great time-saver. However if you change any module/class-level information (variable, sub/function signature, etc), you get the error message like this: "unable to apply this change while debugging" While I can understand the technical challenge to making this work (and why it would be hard), it leaves me in a tight spot with just a few options: 1) Restart and recompile and get the program back to the same state 2) Continue debugging without making the change, and risk forgetting 3) Type up a reminder note to make the change All of which are annoying. Now I know that option '4) Just actually make the change' may not be possible. but does anybody know how to enable the following 'technically easy' possibility? 4) Let me change the code, get it flagged with the purple squiggly underline, so I can save it, but just ignore the change until recompile I have checked the Tools|options|debug|edit and continue, nothing appears to let me do this. thanks!

  • PHP replace backslash

    - by Skyfe
    Hi there, Been struggling with replacing a backslash by another symbol such as '.-.' just to indicate the position of backslashes as I could not send a string such as 'C\xampp\etc.' through url as GET variable so I thought I'd first replace the backslashes in that string by another symbol, then send through url, and then replace them back to backslashes in the PHP file that handles it. Though would there be a better way to send such strings through url? Because when I try a script such as: $tmp_name = preg_replace("\", ".-.", $_FILES['uploadfile']['tmp_name']); It turns out into a php error as \ is also used as delimiter.. Could anyone help me out on this? Thanks in advanced! Btw, if I'd be able to send a full array through url, this whole problem would be solved, but I don't think it's possible?

  • Control within ascx is null when ascx is added from codebehind

    - by Snoop Dogg
    I am having difficulties how to construct my question, but if I have to put it simply the situation is that I have categories of products. I have an aspx with a repeater on the left that lists the categories. And I want the products to be listed on the right. Category number is variable so I made an ascx with a DataList in it. When I try to do foreach category, ascx = new ascx(); then the DataList within this ascx control is null. ps: what I want to do is to preload all the products (thre is not much) and hide the divs and fadein fadeout them using jQuery when a category div is clicked. rightnow it is using jQuery.load(); and I don't like how the images load, cuz they download from top to bottom. Progressive gifs alsdo not an option. site demo is here http://techlipse.net/test/ledart Thanks a lot in advance...

  • Retrieving related data in the Symfony Admin Generator

    - by bjoern
    I have a problem with the Admin Generator. The Table of Pages have the column sf_guard_user_id. The rest of the table looks as this part of the generator.yml in the line display, list: title: Pages display: [=title, sfGuardUser, views, state, privacy, created_at, updated_at] sort: [created_at, desc] fields: sfGuardUser: { label: Author } created_at: { label: Published, date_format: dd.MM.y } updated_at: { label: Updated, date_format: dd.MM.y } table_method: retrieveUserList Now the sf_guard_user_id is been replaced and the username ist displayed. Don't get me wrong, that works fine. But how can I get other variables from the sfGuarsUser relation? When I only add salt or another variable to display I get this, Unknown record property / related component "salt" on "simplePage" But why?

  • Best practice for making code portable for domains, subdomains or directores

    - by Duopixel
    I recently coded something where it wasn't known if the end code would reside in a subdomain (http://user.domain.com/) or in a subdomain (http://domain.com/user), and I was lost as to the best practice for these unknown scenarios. I could thinks of a couple: Use absolute paths (/css/styles.css) and modrewrite if it ends up being /user Have a settings file and declare a variable with the path (<? php echo $domain . "/css/styles" ?>) Use relative paths (../css/styles.css). What is the best way to handle this?

  • EJB3 Caching Instance Variables

    - by Justin
    Hi, I've noticed some strange code on a project I am working on - its a SLSB EJB3, and it uses a private instance variable to maintain a cache of data (it even calls it dataCache or something), with a getter/setter. For EJB2 and bellow, this was a typical EJB antipattern - SLSBs are not meant to retain state in between invocations, theres no guarantee you'll see the same data on a subsequent invocation. One of my colleagues said maybe its ok in EJB3 (we don't have much EJB3 experience), but still, its a Stateless Session Bean - why is it trying to maintain state, this doesn't make sense. Can anyone confirm if this is still a bad idea in EJB3 land, or if somehow it is ok? Thanks if you can help, Justin

  • C++0x regex in GCC

    - by rwallace
    The following code: #include <regex> using namespace std; (snippage) regex_search(s, m, re); works in Microsoft C++, but GCC 4.4.3 gives the following error message: /usr/include/c++/4.4/tr1_impl/regex:2255: warning: inline function ‘bool std::regex_search(_Bi_iter, _Bi_iter, std::match_results<_Bi_iter, _Allocator&, const std::basic_regex<_Ch_type, _Rx_traits&, std::regex_constants::match_flag_type) [with _Bi_iter = __gnu_cxx::__normal_iterator, std::allocator , _Allocator = std::allocator, std::allocator , _Ch_type = char, _Rx_traits = std::regex_traits]’ used but never defined Of course it wouldn't surprise me if regex were simply one of the C++0x features still on the to-do list for GCC, but what I'm scratching my head over is, in that case, why does it happily take the include directive, variable declarations etc. and only trip over the function call (which it even seems to understand). Is there something I'm missing?

  • Flash AS3: crop TextField content off at X lines, add '...' at the end

    - by matt lohkamp
    There's only room for three lines of text in the interface, but the content is external and variable, and if it ends up taking up more than three lines, there needs to be some sort of 'view all' button functionality. I can kind of think about what that function needs to look like, but I'm not quite sure what the best way to do it in AS3 would be. Something like (in pseudo code): function cropText(source:TextField, length:int, append:String):TextField{ if(source.lineCount > length){ source.text = // magic function that retuns the first length lines, // minus append.length characters, with the append value tacked onto the end } return source; } ... right? How would you fill in the missing bit?

  • Google's Geocoder returns wrong country

    - by 6bytes
    Hi I'm using Google's Geocoder to find lat lng coordinates for a given address. var geocoder = new google.maps.Geocoder(); geocoder.geocode( { 'address': address, 'region': 'uk' }, function(results, status) { if(status == google.maps.GeocoderStatus.OK) { lat: results[0].geometry.location.lat(), lng: results[0].geometry.location.lng() }); address variable is taken from an input field. I want to search locations only in UK. I thought that specifying 'region': 'uk' should be enough but it's not. When I type in "Boston" it founds Boston in US and I wanted the one in UK. How to restrict Geocoder to return locations only from one country or maybe from a certain lat lng range? Thanks
