  • Background problem on UITableView

    - by f0rz
    Hi ! I have come to a problem, wich I have no idea how to solve. Can anyone think outside the box and point me to right directions? I would be very thankfull ! The problem. I have a UITableView containing a first row wich is always the same (a empty row with repeating background) Next rows are bounch of dynamic data rows. I have set the yellow background on my UITableView in IBuilder, My cells (except first row) have white background with code: UIView* backgroundView = [ [ [ UIView alloc ] initWithFrame:CGRectZero ] autorelease ]; backgroundView.backgroundColor = [UIColor colorWithRed: 0.96078431372549 green: 0.96078431372549 blue: 0.96078431372549 alpha: 1.0]; cell.backgroundView = backgroundView; for ( UIView* view in cell.contentView.subviews ) { view.backgroundColor = [ UIColor clearColor ]; } The example yellow background, I only want to be showed at the top. As u see img example below. The thing is I dont want to have yellow background under the last datarow, I want to contain same white color I have on the cells. This should be white as the cells. Not yellow. Thank u for your time. Regards

  • GAE datastore querying integer fields

    - by ParanoidAndroid
    I notice strange behavior when querying the GAE datastore. Under certain circumstances Filter does not work for integer fields. The following java code reproduces the problem: log.info("start experiment"); DatastoreService datastore = DatastoreServiceFactory.getDatastoreService(); int val = 777; // create and store the first entity. Entity testEntity1 = new Entity(KeyFactory.createKey("Test", "entity1")); Object value = new Integer(val); testEntity1.setProperty("field", value); datastore.put(testEntity1); // create the second entity by using BeanUtils. Test test2 = new Test(); // just a regular bean with an int field test2.setField(val); Entity testEntity2 = new Entity(KeyFactory.createKey("Test", "entity2")); Map<String, Object> description = BeanUtilsBean.getInstance().describe(test2); for(Entry<String,Object> entry:description.entrySet()){ testEntity2.setProperty(entry.getKey(), entry.getValue()); } datastore.put(testEntity2); // now try to retrieve the entities from the database... Filter equalFilter = new FilterPredicate("field", FilterOperator.EQUAL, val); Query q = new Query("Test").setFilter(equalFilter); Iterator<Entity> iter = datastore.prepare(q).asIterator(); while (iter.hasNext()) { log.info("found entity: " + iter.next().getKey()); } log.info("experiment finished"); the log looks like this: INFO: start experiment INFO: found entity: Test("entity1") INFO: experiment finished For some reason it only finds the first entity even though both entities are actually stored in the datastore and both 'field' values are 777 (I see it in the Datastore Viewer)! Why does it matter how the entity is created? I would like to use BeanUtils, because it is convenient. The same problem occurs on the local devserver and when deployed to GAE.

  • Problem with Mergesort in C++

    - by cambr
    vector<int>& mergesort(vector<int> &a) { if (a.size() == 1) return a; int middle = a.size() / 2; vector<int>::const_iterator first = a.begin(); vector<int>::const_iterator mid = a.begin() + (middle - 1); vector<int>::const_iterator last = a.end(); vector<int> ll(first, mid); vector<int> rr(mid, last); vector<int> l = mergesort(ll); vector<int> r = mergesort(rr); vector<int> result; result.reserve(a.size()); int dp = 0, lp = 0, rp = 0; while (dp < a.size()) { if (lp == l.size()) { result[dp] = (r[rp]); rp++; } else if (rp == r.size()) { result[dp] = (l[lp]); lp++; } else if (l[lp] < r[rp]) { result[dp] = (l[lp]); lp++; } else { result[dp] = (r[rp]); rp++; } dp++; } a = result; return a; } It compiles correctly but while execution, I am getting: This application has requested the runtime to end it in an unusual way. This is a weird error. Is there something that is fundamentally wrong with the code?

  • PHP & cUrl - POST problems in while loop.

    - by Max Hoff
    I have a while loop, with cUrl inside. (I can't use curl_multi for various reasons.) The problem is that cUrl seems to save the data it POSTS after each loop traversal. For instance, if parameter X is One the first loop through, and if it's Two the second loop through, cUrl posts: "One,Two". It should just POST "Two".(This is despite closing and unsetting the curl handle.) Here's a simplified version of the code (with unecessary info stripped out): while(true){ // code to form the $url. this code is local to the loop. so the variables should be "erased" and made new for each loop through. $ch = curl_init(); $userAgent = 'Googlebot/2.1 (http://www.googlebot.com/bot.html)'; curl_setopt($ch,CURLOPT_USERAGENT, $userAgent); curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_POST,count($fields)); curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string); curl_setopt($ch, CURLOPT_FAILONERROR, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); curl_setopt($ch, CURLOPT_AUTOREFERER, true); curl_setopt($ch, CURLOPT_RETURNTRANSFER,true); curl_setopt($ch, CURLOPT_TIMEOUT, 10); $html = curl_exec($ch); curl_close($ch); unset($ch); $dom = new DOMDocument(); @$dom->loadHTML($html); $xpath = new DOMXPath($dom); $resultTable = $xpath->evaluate("/html/body//table"); // $resultTable is 20 the first time through the loop, and 0 everytime thereafter becauset he POSTing doesn't work right with the "saved" parameters. What am I doing wrong here?

  • What's the best way to learn .NET?

    - by duffymo
    I've been developing Java EE for quite a while now. I've used WebLogic, Tomcat, Spring, and Hibernate extensively, so I have a mental model of what features are available and how things are developed and deployed. The problem that I have with .NET is that I don't have a clear mapping of its features onto Java EE. Here's what I know so far: Java EE - .NET Java - C# JAR - DLL WAR - ? (deployment in general) EAR - ? (deployment in general) Tomcat - IIS web server JSP - ASP? JDBC - ODBC JMS - MSMQ JTA - Microsoft Transaction Manager So much of the functionality that WebLogic handles appears to be dispersed throughout the Windows OS. My confusion kicks in when I see the waves of books at Borders - VB.NET, ASP.NET, C#, etc. If I'm not a VB programmer, would it be possible to stick with C# and write enterprise apps that are the equivalent of what I'm used to with Java EE? If there were a Top Three list of books to learn from, what would they be? The "Head First" series has certainly been successful for Java. http://www.amazon.com/Head-First-C-Brain-Friendly-Guides/dp/0596514824/ref=sr_1_1?ie=UTF8&s=books&qid=1224121193&sr=8-1 Equally well recommended for .NET learning? Thanks. - %

  • UIDatePicker date method is picking wrong date: iPhone Dev

    - by prd
    Hi, I am getting very strange behaviour on UIDatePicker. I have a view with date picker declared in .h file as IBOutlet UIDatePicker *datePicker; with property nonatomic and retain. datePicker is properly linked in IB file. In the code I am setting the minimum, maximum, initial date and action to call for UICOntrolEventValueChanged using following code If (!currentDate) { initialDate = [NSDate date]; } else { initialDate = currentdate; } [datePicker setMinimumDate:[NSDate date]]; [datePicker setMaximumDate:[[NSDate date] addTimeInterval:5 * 365.25 * 24 * 60 * 60]]; // to get upto 5 years [datePicker setDate:initialDate animated:YES]; [datePicker addTarget:self action:@selector(getDatePickerValue:) forControlEvents:UIControlEventValueChanged]; In getDatePickerValue, I get the new date using datePicker.date. When the view is closed (using a done button), I get the current value of the date using datePicker.date. Now if the view is called with no 'currentDate', the picker returns 'todays date'. This is what happens the 'first' time my pickerView is called. Each subsequent call to the view, with no 'current date' gives me a different and later date from today. So, first time I get today's date say 9 Jun 2010 second time datePicker.date returns 10 Jun 2010 third time 11 Jun 2010 and so on. Though its not always incremental, but mostly it is. I have put NSLogs, and verified the initial date is set correctly. The problem is only on the device (on OS 3.0), the issue is not replicated on simulator. I can't find what I have done wrong. I hope somebody else has come across similar problem and can help me resolve this.

  • Designing a silverlight dashboard with mef - is it possible? (with dynamic loading of xaps)

    - by Tim Robbin
    Hello! I am just trying to wrap my head around MEF. And as I am really going to love it ( I guess ) I started my first sample project and immediatly stumbled into a big problem and now I am asking myself if I can use MEF for my scenario at all and that is the following: Imagine that one got some kind of dashboard with, let's say, five regions and above each region there are two comboboxes. The values in the first combobox represent different possible views (for example, chartControl, tableControl, pictureControl, ...) and the values of the second combobox represents the different data sources for the currently selected control. As the controls are very big in size one wants to download them as needed. If the user selects one comboboxitem the corresponding control xap should be loaded and displayed in this specific region. If the user selectes another control in the same combobox the control should be removed from the visualtree and the next control should be downloaded and displayed. If the user changes the selection in a different combobox the corresponding control should be loaded again only in this specific region, with perhaps different data. And to make it a little more interesting - as this is some kind of dashboard one can change the layout from five regions to - for example - ten regions. I've seen the video "MVVM with MEF in Silverlight Video Tutorial Part 2: Plugins and Metadata" ( http://csharperimage.jeremylikness.com/2010/03/mvvm-with-mef-in-silverlight-video_09.html ) but he is using an ItemsControl and is working with Visibility and he only got ONE region. So I think that this technique is not working for me... Puh, I hope I could make myself clear! Thanks a lot for any piece of information!!! Greetings, Tim.

  • Problem with document.location.href

    - by novellino
    Hello, I am new to Javascript and Web development and I have a question regarding the document.location.href. I am using a cookie for storing the language the user prefers and then load the english or the swedish version depending on the language. The default language in the beginning is the same as the browser's language, and my index.jsp is the swedish one. The first time everything works fine. The problem is when the cookie exists already. The basic code is: if (language!=null && language!=""){ if (language=="en-US" || language=="en-us") document.location.href = "en/index.jsp"; } else{ //Explorer if (navigator.userLanguage) language = navigator.userLanguage; //other browsers else language = (navigator.language) ? navigator.language : navigator.userLanguage; if (language!=null && language!=""){ setCookie('language', language, 365, '/', 'onCheck'); if (language=="en-US" || language=="en-us") document.location.href = "en/index.jsp"; else if(language=="sv") document.location.href="index.jsp"; } } When the cookie exists we enter the first "if", and there, if the language is swedish it opens the default blabla/index.jsp page. When the language is set to engish it should open the blabla/en/index.jsp but instead it opens the blabla/en/en/index.jsp which of course is wrong. Does anyone know what I am doing wrong?? Thanks

  • Session hijacking prevention...how far will my script get me? additional prevention procedures?

    - by Yusaf Khaliq
    When the user logs in the current session vairables are set $_SESSION['user']['timeout'] = time(); $_SESSION['user']['ip'] = $_SERVER['REMOTE_ADDR']; $_SESSION['user']['agent'] = $_SERVER['HTTP_USER_AGENT']; In my common.php page (required on ALL php pages) i have used the below script, which resets a 15 minute timer each time the user is active furhtermore checks the IP address and checks the user_agent, if they do not match that as of when they first logged in/when the session was first set, the session is unset furthermore with inactivity of up to 15 minutes the session is also unset. ... is what i have done a good method for preventing session hijacking furthermore is it secure and or is it enough? If not what more can be done? if(!empty($_SESSION['user'])){ if ($_SESSION['user']['timeout'] + 15 * 60 < time()) { unset($_SESSION['user']); } else { $_SESSION['user']['timeout'] = time(); if($_SESSION['user']['ip'] != $_SERVER['REMOTE_ADDR']){ unset($_SESSION['user']); } if($_SESSION['user']['agent'] != $_SERVER['HTTP_USER_AGENT']){ unset($_SESSION['user']); } } }

  • How to start with AJAX/JSON in Zend?

    - by Awan
    I am working on some projects as a developer(PHP,MySQL) in which AJAX and jQuery is already implemented. But now I want to learn implementation of AJAX and jQuery stuff. Can anyone tell me the exact steps with explanation? I have created a project in Zend. There is only one controller(IndexController) and two actions(a and b) in my project now. Now I want to use ajax in my project. But I don't know how to start. I read some tutorial but unable to completely understand. I have index.phtml like this: <a href='index/a'>Load info A</a> <br/> <a href='index/b'>Load info B</a> <br /> <div id=one>load first here<div> <div id=two>load second here</div> Here index is controller in links. a and b are actions. now I have four files like this: a1.phtml I am a1 a2.phtml I am a2 b1.phtml I am b1 b2.phtml I am b2 I think you have got my point. When user clicks first link (Load info A) then a1.phtml should be loaded into div one and a2.phtml should be loaded into div two When user clicks second link (Load info B) then b1.phtml should be loaded into div one and b2.phtml should be loaded into div two And someone tell me the purpose of JSON in this process and how to use this also? Thanks

  • Practiaal rules for Django MiddleWare ordering?

    - by o_O Tync
    The official documentation is a bit messy: 'before' & 'after' are used for ordering MiddleWare in a tuple, but in some places 'before'&'after' refers to request-response phases. Also, 'should be first/last' are mixed and it's not clear which one to use as 'first'. I do understand the difference.. however it seems to complicated for a newbie in Django. Can you suggest some correct ordering for builtin MiddleWare classes (assuming we enable all of them) and — most importantly — explain WHY one goes before/after other ones? here's the list, with the info from docs I managed to find: UpdateCacheMiddleware Before those that modify 'Vary:' SessionMiddleware, GZipMiddleware, LocaleMiddleware GZipMiddleware Before any MW that may change or use the response body After UpdateCacheMiddleware: Modifies 'Vary:' ConditionalGetMiddleware Before CommonMiddleware: uses its 'Etag:' header when USE_ETAGS=True SessionMiddleware After UpdateCacheMiddleware: Modifies 'Vary:' Before TransactionMiddleware: we don't need transactions here LocaleMiddleware, One of the topmost, after SessionMiddleware, CacheMiddleware After UpdateCacheMiddleware: Modifies 'Vary:' After SessionMiddleware: uses session data CommonMiddleware Before any MW that may change the response (it calculates ETags) After GZipMiddleware so it won't calculate an E-Tag on gzipped contents Close to the top: it redirects when APPEND_SLASH or PREPEND_WWW CsrfViewMiddleware AuthenticationMiddleware After SessionMiddleware: uses session storage MessageMiddleware After SessionMiddleware: can use Session-based storage XViewMiddleware TransactionMiddleware After MWs that use DB: SessionMiddleware (configurable to use DB) All *CacheMiddleWare is not affected (as an exception: uses own DB cursor) FetchFromCacheMiddleware After those those that modify 'Vary:' if uses them to pick a value for cache hash-key After AuthenticationMiddleware so it's possible to use CACHE_MIDDLEWARE_ANONYMOUS_ONLY FlatpageFallbackMiddleware Bottom: last resort Uses DB, however, is not a problem for TransactionMiddleware (yes?) RedirectFallbackMiddleware Bottom: last resort Uses DB, however, is not a problem for TransactionMiddleware (yes?) (I will add suggestions to this list to collect all of them in one place)

  • Clearing input text feilds when clicked on in Flash (AS 2.0)

    - by rickstyphilis
    I have a problem where I want a text field that by default has the word NAME in it, to become empty when a user clicks on it. The text field has the instance name 'nam' and is inside a movie with the instance name 'input_text'. I've searched around and found samples of code where everyone keeps suggesting this: textboxinstancename.onSetFocus = function() { textboxinstancename.text = ""; }; should work. It seems to work for everyone else but me. I've tried using the following on the first frame of the 'input_text' movie with no luck: this.input_text.nam.onSetFocus = function() { this.input_text.nam.text = "" } I've tried putting this on the first frame of the scene, again with no result: _root.input_text.nam.onSetFocus = function() { _root.input_text.nam.text = "" } I've tried this in the same manner as the last respectively with both 'this' on the instance and '_root' on the scene (denoted by x): x.input_text.nam.onSetFocus = function() { if (x.input_text.nam.text == "NAME") { x.input_text.nam.text = ""; } }; Still no luck. Can anyone tell me what I might be doing wrong?

  • Clustered index - multi-part vs single-part index and effects of inserts/deletes

    - by Anssssss
    This question is about what happens with the reorganizing of data in a clustered index when an insert is done. I assume that it should be more expensive to do inserts on a table which has a clustered index than one that does not because reorganizing the data in a clustered index involves changing the physical layout of the data on the disk. I'm not sure how to phrase my question except through an example I came across at work. Assume there is a table (Junk) and there are two queries that are done on the table, the first query searches by Name and the second query searches by Name and Something. As I'm working on the database I discovered that the table has been created with two indexes, one to support each query, like so: --drop table Junk1 CREATE TABLE Junk1 ( Name char(5), Something char(5), WhoCares int ) CREATE CLUSTERED INDEX IX_Name ON Junk1 ( Name ) CREATE NONCLUSTERED INDEX IX_Name_Something ON Junk1 ( Name, Something ) Now when I looked at the two indexes, it seems that IX_Name is redundant since IX_Name_Something can be used by any query that desires to search by Name. So I would eliminate IX_Name and make IX_Name_Something the clustered index instead: --drop table Junk2 CREATE TABLE Junk2 ( Name char(5), Something char(5), WhoCares int ) CREATE CLUSTERED INDEX IX_Name_Something ON Junk2 ( Name, Something ) Someone suggested that the first indexing scheme should be kept since it would result in more efficient inserts/deletes (assume that there is no need to worry about updates for Name and Something). Would that make sense? I think the second indexing method would be better since it means one less index needs to be maintained. I would appreciate any insight into this specific example or directing me to more info on maintenance of clustered indexes.

  • How to store an inventory using hashtables?

    - by Harm De Weirdt
    Hello everyone. For an assignment in collego we have to make a script in Perl that allows us to manage an inventory for an e-store. (The example given was Amazon) Users can make orders in a fully text-based environment and the inventory must be updated when an order is completed. Every item in the inventory has 3 to 4 attributes: a product code, a title, a price and for some an amount (MP3's for example do not have this attribute) Since this is my first encounter with Perl, i don't really know how to start. My main problem is how i should "implement" the inventory in the program. One of the functions of the program is searching trough the titles. Another is to make an order, where the user should give a product code. My first idea was a hashtable with the productcode as key. But if i wanted to search in the titles that could be a problem because of this: the hashkey would be something like DVD-123, the information belonging to that key could be "The Green Mask 12" (without the ") where the 12 indicates how many of this DVD are currently in stock. So i'd have to find a way to ignore the 12 in the end. Another solution was to use the title as Hashkey, but that would prove cumbersome too I think. Is there a way to make a hashtable with 2 key's, and when I give only one it returns an array with the other values? (Including the other key and the other information) That way I could use another key depending on what info I need from my inventory. We have to read the default inventory from a txt file looking like this: MP3-72|Lady Gaga - Kiss and Run (Fear of Commitment Monster)|0.99 CD-400|Kings of Leon - Only By The Night|14.50|2 MP3-401|Kings of Leon - Closer|0.85 DVD-144|Live Free or Die Hard|14.99|2 SOFT-864|Windows Vista|49.95 Any help would be appreciated very much :) PS: I am sorry for my bad grammar, English isn't my native language.

  • Jquery problem - cant expand the row above in a table

    - by apg1985
    Hi People, What I cant figure out is how I would toggle a row in a table using the one below it. So say I have a table with 2 rows the first contains content and the one below contains a button, when the page loads the content row is hidden and when you click the button it toggles the content row on and off. In the example the first table works but the second does not, I need the second one to work. <!DOCTYPE HTML> <html> <head> <title>Testing Horizontal Accordion</title> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> $(document).ready(function() { $(".sectionhead").toggle( function() { $(this).next("tr").hide(); }, function() { $(this).next("tr").show(); } ) }); </script> </head> <body> <table> <tr class="sectionhead"><td></td></tr> <tr class="child"><td>child</td></tr> </table> <br> <table> <tr class="child"><td>child</td></tr> <tr class="sectionhead"><td></td></tr> </table> </body> </html>

  • Volatile fields in C#

    - by Danny Chen
    From the specification 10.5.3 Volatile fields: The type of a volatile field must be one of the following: A reference-type. The type byte, sbyte, short, ushort, int, uint, char, float, bool, System.IntPtr, or System.UIntPtr. An enum-type having an enum base type of byte, sbyte, short, ushort, int, or uint. First I want to confirm my understanding is correct: I guess the above types can be volatile because they are stored as a 4-bytes unit in memory(for reference types because of its address), which guarantees the read/write operation is atomic. A double/long/etc type can't be volatile because they are not atomic reading/writing since they are more than 4 bytes in memory. Is my understanding correct? And the second, if the first guess is correct, why a user defined struct with only one int field in it(or something similar, 4 bytes is ok) can't be volatile? Theoretically it's atomic right? Or it's not allowed simply because that all user defined structs(which is possibly more than 4 bytes) are not allowed to volatile by design?

  • Drupal6: How to programmatically style a block?

    - by Fronker
    In Drupal6, I basically have a block (a hierarchical menu structure) that turns out like this in HTML: <div class="block block-menu_block" id="block-menu_block-1"> <div class="content"> <div class="menu-block-1 menu-name-menu-navigation parent-mlid-0 menu-level-1"> <ul class="menu"> <li class="leaf first menu-mlid-248 active active-trail"><a class="active-trail active" title="" href="/">Start</a></li> <li class="expanded menu-mlid-249 active"><a class="active" title="" href="/">Aktuell</a> <ul class="menu"> <li class="leaf first menu-mlid-259"> <a title="News und Presse" href="/news-und-presse">News and Press</a> </li>... What I would like to get is actually a lot simpler: <div id="topmenu"> <ul class="one"> <li>some main entry <ul> <li> some sub entry ... or maybe: <div id="topmenu"> <h2>some main entry</h2> <h3><a href="#">some sub entry</a></h3> <h3><a href="#">another sub entry</a></h3> <h2>another main entry</h2> So, keeping the structure, but being able to use simpler, even completely different tags, if and when needed. I think I understand from the drupal docs, that I am (maybe) looking at <div class="block block-menu_block" id="block-menu_block-1" ==> module := menu_block delta := 1 (?) regrettably, none of the suggested * block-[module]-[delta].tpl.php * block-[module].tpl.php * block-[region].tpl.php placed next to page.tpl.php has any impact (yes, I did clear the cache).

  • How do you save and retrieve a Key/IV pair securely?

    - by Shawn Steward
    I'm using VB.Net's RijndaelManaged (RM) to encrypt files, using the RM.GenerateKey and RM.GenerateIV methods to generate the Key and IV and encrypting the file using the CryptoStream class. I'm planning on saving this Key and IV to a file and want to make sure I'm doing it the right way. I am combining the IV+Key, and encrypting that with my RSA Public key and writing it out to a file. Then, to decrypt I use the RSA Private key on this file to get the IV+Key, split them up and set RM.Key and RM.IV to these values and run the decryptor. Is this the best method to accomplish this, or is there a preferred method for saving the IV & Key? Also, what's the best way to construct and deconstruct the byte array? I used the .Concat method to join them together and that seems to work well but I can't seem to find something as easy to deconstruct it. I played with the .Take method that takes the first x # of bytes and it works for the first part but can't find anything that gets the rest of it.

  • Sequential animations in Jquery

    - by Pickels
    I see a lot people struggling with this(me included). I guess it's mostly due to not perfectly knowing how Javascript scopes work. An image slideshow is a good example of this. So lets say you have series of images, the first one fades in = waits = fades out = next image. When I first created this I was already a little lost. I think the biggest problem for creating the basics is to keep it clean. I noticed working with callbacks can get uggly pretty fast. So to make it even more complicated most slideshows have control buttons. Next, previous, go to img, pause, ... I've been trying this for a while now and this is where I got: $(InitSlideshow); function InitSlideshow() { var img = $("img").hide(); var animate = { wait: undefined, start: function() { img.fadeIn(function() { animate.middle(); }); }, middle: function() { animate.wait = setTimeout(function() { animate.end(); }, 1000); }, end: function() { img.fadeOut(function() { animate.start(); }); }, stop: function() { img.stop(); clearTimeout(animate.wait); } }; $("#btStart").click(animate.start); $("#btStop").click(animate.stop); }; This code works(I think) but I wonder how other people deal with sequentials animations in Jquery? Tips and tricks are most welcome. So are links to good resources dealing with this issue. If this has been asked before I will delete this question. I didn't find a lot of info about this right away. I hope making this community wiki is correct as there is not one correct answer to my question. Kind regards, Pickels

  • How to convert String format dates to Date format dates?

    - by Jani Bela
    I have a string with dates it looks like: "20120316 20120317 20120318" ... I store this dates in this format, but I would like to make a Date array from these numbers with the format 03/16 03/17 03/18 ... So far: String[] DailyDatasOnce2 = DatesOnce.split(" "); DailyDatasOnce = new String[DailyDatasOnce2.length]; for (int i=0;i< (DailyDatasOnce2.length) ;i++){ DailyDatasOnce[i]=DailyDatasOnce2[i]; } datumok = new Date[DailyDatasOnce.length]; for (int i=0;i< (DailyDatasOnce.length) ;i++){ SimpleDateFormat curFormater = new SimpleDateFormat("yyyyMMdd"); java.util.Date dateObj = null; java.util.Date dateObj2 = null; try { dateObj = curFormater.parse(DailyDatasOnce[i]); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } SimpleDateFormat postFormater = new SimpleDateFormat("MM/dd"); String newDateStr = postFormater.format(dateObj); try { dateObj2 = curFormater.parse(newDateStr); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } datumok[i] = dateObj2; } So first I make a string array with the string dates (DailyDatasOnce), maybe that first for loop is useless but i can skip it. Now I make a Date array and I want to put the dates into it. I format the dates to format I want, then I try to convert them to Date format. Until the String newDateStr it is working, I manage to change the type of the date. But I get syntax error: Type mismatch: Cannot convert from java.util.date to java.sql.data. I suspect the problem but if it is not possible, how can i do this?

  • The fastest way to iterate through a collection of objects

    Hello all, First to give you some background: I have some research code which performs a Monte Carlo simulation, essential what happens is I iterate through a collection of objects, compute a number of vectors from their surface then for each vector I iterate through the collection of objects again to see if the vector hits another object (similar to ray tracing). The pseudo code would look something like this for each object { for a number of vectors { do some computations for each object { check if vector intersects } } } As the number of objects can be quite large and the amount of rays is even larger I thought it would be wise to optimise how I iterate through the collection of objects. I created some test code which tests arrays, lists and vectors and for my first test cases found that vectors iterators were around twice as fast as arrays however when I implemented a vector in my code in was somewhat slower than the array I was using before. So I went back to the test code and increased the complexity of the object function each loop was calling (a dummy function equivalent to 'check if vector intersects') and I found that when the complexity of the function increases the execution time gap between arrays and vectors reduces until eventually the array was quicker. Does anyone know why this occurs? It seems strange that execution time inside the loop should effect the outer loop run time.

  • How to use a loop to download HTML with paging?

    - by Nai
    I want to loop through this URL and download the HTML. https://www.googleapis.com/customsearch/v1?key=AIzaSyAAoPQprb6aAV-AfuVjoCdErKTiJHn-4uI&cx=017576662512468239146:omuauf_lfve&q=" + searchTermFormat + "&num=10" +"&start=" + i start and num controls the paging of the URL. So if &start=2, and &num=10, it will scrape 10 results from page 2. Given that Google has a max limit of num = 10, how can I write a loop that loops through the HTML and scrape the results for the first 10 pages? This is what I have so far which just scrapes the first page. //input search term Console.WriteLine("What is your search query?:"); string searchTerm = Console.ReadLine(); //concantenate the strings using + symbol to make it URL friendly for google string searchTermFormat = searchTerm.Replace(" ", "+"); //create a new instance of Webclient and use DownloadString method from the Webclient class to extract download html WebClient client = new WebClient(); int i = 1; string Json = client.DownloadString("https://www.googleapis.com/customsearch/v1?key=AIzaSyAAoPQprb6aAV-AfuVjoCdErKTiJHn-4uI&cx=017576662512468239146:omuauf_lfve&q=" + searchTermFormat + "&num=10" + "&start=" + i); //create a new instance of JavaScriptSerializer and deserialise the desired content JavaScriptSerializer js = new JavaScriptSerializer(); GoogleSearchResults results = js.Deserialize<GoogleSearchResults>(Json); //output results to console Console.WriteLine(js.Serialize(results)); Console.ReadLine();

  • Dynamic Control loading at wrong time?

    - by Telos
    This one is a little... odd. Basically I have a form I'm building using ASP.NET Dynamic Data, which is going to utilize several custom field templates. I've just added another field to the FormView, with it's own custom template, and the form is loading that control twice for no apparent reason. Worse yet, the first time it loads the template, the Row is not ready yet and I get the error message: {"Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."} I'm accessing the Row variable in a LinqDataSource OnSelected event in order to get the child object... Now for the wierd part: If I reorder the fields a little, the one causing the problem no longer gets loaded twice. Any thoughts? EDIT: I've noticed that Page_Load gets called on the first load (when Row throws an exception if you try to use it) but does NOT get called the second time around. If that helps any... Right now managing it by just catching and ignoring the exception, but still a little worried that things will break if I don't find the real cause. EDIT 2: I've traced the problem to using FindControl recursively to find other controls on the page. Apparently FindControl can cause the page lifecycle events (at least up to page_load) to fire... and this occurs before that page "should" be loading so it's dynamic data "stuff" isn't ready yet.

  • movie does not start in full screen in flash video player

    - by jodeci
    We have this legacy code of a flash video player that functions well enough but still has some loose ends I need to tighten up. It can do the basic "switch to full screen and back to normal size" stunts, however with one exception. On the first fresh load of the app, if I switch to full screen mode first, and then click to play the movie, the player would be in full screen, yet the movie itself would remain in it's original size. //trigger if (stage.displayState == StageDisplayState.NORMAL) { stage.addEventListener('fullScreen', procFullScreen); stage.scaleMode = StageScaleMode.NO_SCALE; stage.displayState = StageDisplayState.FULL_SCREEN; //mv:VideoDisplay mv.percentHeight = 100; mv.percentWidth = 100; mv.x = 0; mv.y = 0; } // event handler if (event.fullScreen) { mv.smoothing = true; this.height = stage.height; this.width = stage.width; //videoCanvas:Canvas videoCanvas.height = Application.application.height; videoCanvas.width = Application.application.width; fullScreenViewStack.selectedIndex = 1; } The VideoDisplay object even returns the expected width/height, but the movie just plays in it's original size. If I switch screen sizes during movie playback, then the movie size will shrink or stretch as it should. I'm running out of ideas, any suggestions? Thanks in advance!

  • Increment part of a string in Ruby

    - by Rik
    I have a method in a Ruby script that is attempting to rename files before they are saved. It looks like this: def increment (path) if path[-3,2] == "_#" print " Incremented file with that name already exists, renaming\n" count = path[-1].chr.to_i + 1 return path.chop! << count.to_s else print " A file with that name already exists, renaming\n" return path << "_#1" end end Say you have 3 files with the same name being saved to a directory, we'll say the file is called example.mp3. The idea is that the first will be saved as example.mp3 (since it won't be caught by if File.exists?("#{file_path}.mp3") elsewhere in the script), the second will be saved as example_#1.mp3 (since it is caught by the else part of the above method) and the third as example_#2.mp3 (since it is caught by the if part of the above method). The problem I have is twofold. 1) if path[-3,2] == "_#" won't work for files with an integer of more than one digit (example_#11.mp3 for example) since the character placement will be wrong (you'd need it to be path[-4,2] but then that doesn't cope with 3 digit numbers etc). 2) I'm never reaching problem 1) since the method doesn't reliably catch file names. At the moment it will rename the first to example_#1.mp3 but the second gets renamed to the same thing (causing it to overwrite the previously saved file). This is possibly too vague for Stack Overflow but I can't find anything that addresses the issue of incrementing a certain part of a string. Thanks in advance!
