  • Working with three dimensional data in an HTML (ASP.NET) table.

    - by ProfK
    I am working on the prototype for a scheduling application on an intranet system. The application is for scheduling and tracking promotional workers at various locations on various dates (hence location, date, workers dimensions). Currently, only for prototyping, I am generating a data table of location/date, and from this I iteratively build an HTML table (asp:Table control). On visiting each cell, I query for people working that location-date and populate the cell accordingly. This is very inefficiant, and will at worst be improved by querying cached data for the whole location/date grid. I'm looking around for established patterns and techniques for dealing with scenarios like this in HTML in general, maybe a visualisation library for jQuery or something, and for ASP.NET in particular, maybe a library for implementation on a GridView etc. Am I going in the right direction with this, and if so, what recomendations are there regarding the previous paragraph?

  • Developing GWT without a net connection?

    - by user246114
    Hi, When I'm developing my gwt project without a network connection, is there a way to detect this? For example, I have a widget that has an Image in it, and the widget does not display until the Image url request times out (takes a long time, like 2 minutes?). Also, whenever I refresh the page in hosted mode, it doesn't finish loading for about a minute, when no network connection - seems like gwt is trying to contact some external website and blocking on that until it times out too - making things really slow - any way to stop that too? Thanks

  • How to debug iPhone project crash when there is no error message

    - by teepusink
    Hi, I am doing this iPhone app that works fine on the simulator. However, when I run it on a device in debug mode, it just crash without any error messages. How can I debug that? I heard about a flag we can set to help with this kind of situation but not sure what that flag is and how to set it. If I'm not mistaken I think what that flag does is put a break point automatically prior to crash. Thanks, Tee

  • Getting a list of all phone contacts?

    - by pcm2a
    Simple enough question. I need to know the best way to get the same list of contacts that show up when a user presses the Contacts button. You would think something like this would work: //For Contacts Intent pickIntent = new Intent(Intent.ACTION_PICK, People.CONTENT_URI); this.startActivityForResult(pickIntent, RESULT); //For Phones Intent pickIntent = new Intent(Intent.ACTION_PICK, Phones.CONTENT_URI); this.startActivityForResult(pickIntent, RESULT); The problem is that does not include secondary google accounts or Exchange contacts. By secondary accounts, in Android you can add additional gmail accounts to have the mail/contacts synced. The above intent will not list those additional contacts. I am also told that on the HTC Desire you can add contacts to the phone that do not get synced up to Google. These contacts also do not show up. So how do I get a real list of contacts so I can create my own list activity that works properly where the Google intent does not.

  • Execute a method less times possible - PHP

    - by serhio
    I have a site in multiple languages. I have a method that returns me the today currencies in a array. I display that currencies in a table then. // --- en/index.php <?php include_once "../exchangeRates.php"; $currencies = ReadExchangeRates(); // --- fr/index.php <?php include_once "../exchangeRates.php"; $currencies = ReadExchangeRates(); ... // somewhere in the page <td><?php echo $currencies["eur"]["today"]; ?></td> So, every time I load, en/ or fr/ or other language, I request the exchange rates from a external site. Can I optimize this behavior (reading once per day or session)? maybe to store a global variable and check the update date?

  • How to Prevent an Applet from Unloading across web pages?

    - by Francis Shanahan
    I have a large applet that takes some 40 seconds to initialize (cabs are cached so ignore download time for this question). The issue is, if the user goes to Page A which launches the applet (single window) and then navigates to page B, the applet is unloaded. If the user goes back to Page A, they incur the 40 seconds init time once again. I'd like to be able to launch the applet, incurring the 40 seconds init time once and only once. The applet needs to reside inside a single browser window (the same window as my web application). In other words, I cannot launch the applet in a popup. Does anyone have any creative ideas around how to prevent the applet unloading?

  • Background task in mobile phone to access a secure element and a web server

    - by Splryxx
    Is it possible in a GSM mobile phone OS (e.g. Android, Win Mo, Symbian, etc.) to have some kind of background task or application able to exchange data at the same time with a web server and a secure element of the mobile? The purpose if for the web server to be able to push APDUs to the secure element (an retrieve response APDUs) without activating the IHM of the mobile. NB: I know that this is possible when the secure element is the one managing the GSM baseband, for example using BIP as described in Ulysse specifications. My question is only when using another secure element (e.g. Java Card in a microSD).

  • MySQL MATCH AGAINST functionality....

    - by Webnet
    Currently I have the following query... SELECT id, LOWER(title) as title, LOWER(sub_title) as sub_title FROM ebay_archive_listing WHERE MATCH(title, sub_title) AGAINST ("key" IN BOOLEAN MODE) However it is not finding rows where the title contains the word "key". "key" is generated dynamically based on a set of keywords, so sometimes it contains + and - symbols.

  • Convert a string representation of a hex dump to a byte array using Java?

    - by ravigad
    I am looking for a way to convert a long string (from a dump), that represents hex values into a byte array. I couldn't have phrased it better than the person that posted the same question here: http://www.experts-exchange.com/Programming/Programming_Languages/Java/Q_21062554.html But to keep it original, I'll phrase it my own way: suppose I have a string "00A0BF" that I would like interpreted as the byte[] {0x00,0xA0,0xBf} what should I do? I am a Java novice and ended up using BigInteger and watching out for leading hex zeros. But I think it is ugly and I am sure I am missing something simple...

  • SQLAlchemy: an efficient/better select by primary keys?

    - by hadrien
    Yet another newbie question.. Let's say I have an user table in declarative mode: class User(Base): __tablename__ = 'user' id = Column(u'id', Integer(), primary_key=True) name = Column(u'name', String(50)) When I have a list of users identifiers, I fetch them from db with: user_ids = [1, 2, 3, 4, 5] users = Session.query(User).filter(User.id.in_(user_ids)).all() I dislike using in_ because I think I learned it has bad performance on indexed fields (is that true/false?). Anyway, is there a better way doing that query? Thanks!

  • Replacing keywords in text with php & mysql

    - by intacto
    Hello, I have a news site containing an archive with more than 1 million news. I created a word definitions database with about 3000 entries, consisting of word-definition pairs. What I want to do is adding a definition next to every occurence of these words in the news. I cant make a static change as I can add a new keyword everyday, so i can make it realtime or cached. The question is, a str_replace or a preg_replace would be very slow for searching 3 thousand keywords in a text and replacing them. Are there any fast alternatives?

  • Windows fonts not immediately useable in application after installing?

    - by Jappie
    Whenever I install a new font on a Windows 2003 server, I can't use it immediately in my asp.net web application. The application gets the font through the CreateFontIndirect gdi32.dll win api. It seems like fonts get cached somewhere, because I will just get the default font returned. The font cache gets updated after a reboot, and then I get the correct font, but obviously I wouldn't like to do a reboot on a production server just for getting a new font to work. Is there a way to flush the font cache?
