  • Using client time to calculate timezone

    - by Mike TK
    Hi Folks, Instead of asking a client timezone in registration form (to correctly format datetime, all server dates in UTC) I thought about fetching a time from client computer and calculating time offset between client and server. Anyone tried this? How often clients have something insane on their system clocks? Cheers!

  • jQuery: Execute function after all ajax .load() requests are finished

    - by Mike
    I have a page that has a tab set. Each of the tabs is loaded by the jQuery .load() function. I want to display a loading animation that disappears when all of the ajax requests are finished. However, document.ready() has only provided me with limited success. How can I ensure that all ajax requests are completed before executing the code to hide the loading animation? Thanks!

  • C# Combining lines

    - by Mike
    Hey everybody, this is what I have going on. I have two text files. Umm lets call one A.txt and B.txt. A.txt is a config file that contains a bunch of folder names, only 1 listing per folder. B.txt is a directory listing that contains folders names and sizes. But B contains a bunch of listing not just 1 entry. What I need is if B, contains A. Take all lines in B that contain A and write it out as A|B|B|B ect.... So example: A.txt: Apple Orange Pear XBSj HEROE B.txt: Apple|3123123 Apple|3434 Orange|99999999 Orange|1234544 Pear|11 Pear|12 XBSJ|43949 XBSJ|43933 Result.txt: Apple|3123123|3434 Orange|99999999|1234544 Pear|11|12 XBSJ|43949|43933 This is what I had but it's not really doing what I needed. string[] combineconfig = File.ReadAllLines(@"C:\a.txt"); foreach (string ccline in combineconfig) { string[] readlines = File.ReadAllLines(@"C:\b.txt"); if (readlines.Contains(ccline)) { foreach (string rdlines in readlines) { string[] pslines = rdlines.Split('|'); File.AppendAllText(@"C:\result.txt", ccline + '|' + pslines[0]); } } I know realize it's not going to find the first "if" because it reads the entire line and cant find it. But i still believe my output file will not contain what I need.

  • Setting a preferred item of a many-to-one in Django

    - by Mike DeSimone
    I'm trying to create a Django model that handles the following: An Item can have several Names. One of the Names for an Item is its primary Name, i.e. the Name displayed given an Item. (The model names were changed to protect the innocent.) The models.py I've got looks like: class Item(models.Model): primaryName = models.OneToOneField("Name", verbose_name="Primary Name", related_name="_unused") def __unicode__(self): return self.primaryName.name class Name(models.Model): item = models.ForeignKey(Item) name = models.CharField(max_length=32, unique=True) def __unicode__(self): return self.name class Meta: ordering = [ 'name' ] The admin.py looks like: class NameInline(admin.TabularInline): model = Name class ItemAdmin(admin.ModelAdmin): inlines = [ NameInline ] admin.site.register(Item, ItemAdmin) It looks like the database schema is working fine, but I'm having trouble with the admin, so I'm not sure of anything at this point. My main questions are: How do I explain to the admin that primaryName needs to be one of the Names of the item being edited? Is there a way to automatically set primaryName to the first Name found, if primaryName is not set, since I'm using inline admin for the names?

  • PHP: Manage roles with math?

    - by Mike
    I once saw an article about how to use a specific type of numbering system to manage roles. A user would be assigned a specific role number and depending on a calculation, the number could stand for multiple roles. Can anybody share this technique with me or share a link? Thanks!

  • SimpleXMLElement empty object

    - by Mike
    Hi, I am trying to parse an xml file using XmlReader but although I am getting a return from the xml file for the (commission) node for some reason I am getting an empty SimpleXMLElement Object returned as well. I don't know if its something to do with while loop,switch or something I missed in the parse setup. This is the xml file I am trying to read from, as you can see there is only 1 result returned: <?xml version="1.0" encoding="UTF-8"?> <cj-api> <commissions total-matched="1"> <commission> <action-status> new </action-status> <action-type> lead </action-type> <aid> 10730981 </aid> <commission-id> 1021015513 </commission-id> <country> </country> <event-date> 2010-05-08T08:08:55-0700 </event-date> <locking-date> 2010-06-10 </locking-date> <order-id> 345007 </order-id> <original> true </original> <original-action-id> 787692438 </original-action-id> <posting-date> 2010-05-08T10:01:22-0700 </posting-date> <website-id> 3201921 </website-id> <cid> 2815954 </cid> <advertiser-name> SPS EurosportBET </advertiser-name> <commission-amount> 0 </commission-amount> <order-discount> 0 </order-discount> <sid> 0 </sid> <sale-amount> 0 </sale-amount> </commission> </commissions> </cj-api> This is my parser: <?php // read $response (xml feed) $file = "datafeed.xml"; $xml = new XMLReader; $xml->open($file); // loop to read in data while ($xml->read()) { switch ($xml->name) { // find the parent node for each commission payment case 'commission': // initalise xml parser $dom = new DomDocument(); $dom_node = $xml ->expand(); $element = $dom->appendChild($dom_node); $dom_string = $dom->saveXML($element); $commission = new SimpleXMLElement($dom_string); // read in data $action_status = $commission->{'action-status'}; $action_type = $commission->{'action-type'}; $aid = $commission->{'aid'}; $commission_id = $commission->{'commission-id'}; $country = $commission->{'country'}; $event_date = $commission->{'event-date'}; $locking_date = $commission->{'locking-date'}; $order_id = $commission->{'order-id'}; $original = $commission->{'original'}; $original_action_id = $commission->{'original_action-id'}; $posting_date = $commission->{'posting-date'}; $website_id = $commission->{'website-id'}; $cid = $commission->{'cid'}; $advertiser_name = $commission->{'advertiser-name'}; $commission_amount = $commission->{'commission-amount'}; $order_discount = $commission->{'order-discount'}; $sid = $commission->{'sid'}; $sale_amount = $commission->{'sale-amount'}; print_r($aid); break; } } ?> The result is : SimpleXMLElement Object ( [0] => 10730981 ) SimpleXMLElement Object ( ) Why is it returning the second object: SimpleXMLElement Object ( ) and what do I need to do correct it? Thanks.

  • "Invalid use of Null" when using Str() with a Null Recordset field, but Str(Null) works fine

    - by Mike Spross
    I'm banging my head against the wall on this one. I was looking at some old database reporting code written in VB6 and case across this line (the code is moving data from a "source" database into a reporting database): rsTarget!VehYear = Trim(Str(rsSource!VehYear)) When rsSource!VehYear is Null, the above line generates an "Invalid use of Null" run-time error. If I break on the above line and type the following in the Immediate pane: ?rsSource!VehYear It outputs Null. Fine, that makes sense. Next, I try to reproduce the error: ?Str(rsSource!VehYear) I get an "Invalid use of Null" error. However, if I type the following into the Immediate window: ?Str(Null) I don't get an error. It simply outputs Null. If I repeat the same experiment with Trim() instead of Str(), everything works fine. ?Trim(rsSource!VehYear) returns Null, as does ?Trim(Null). No run-time errors. So, my question is, how can Str(rsSource!VehYear) possibly throw an "Invalid use of Null" error when Str(Null) does not, when I know that rsSource!VehYear is equal to Null?

  • Pattern for version-specific implementations of a Java class

    - by Mike Monkiewicz
    So here's my conundrum. I am programming a tool that needs to work on old versions of our application. I have the code to the application, but can not alter any of the classes. To pull information out of our database, I have a DTO of sorts that is populated by Hibernate. It consumes a data object for version 1.0 of our app, cleverly named DataObject. Below is the DTO class. public class MyDTO { private MyWrapperClass wrapper; public MyDTO(DataObject data) { wrapper = new MyWrapperClass(data); } } The DTO is instantiated through a Hibernate query as follows: select new com.foo.bar.MyDTO(t1.data) from mytable t1 Now, a little logic is needed on top of the data object, so I made a wrapper class for it. Note the DTO stores an instance of the wrapper class, not the original data object. public class MyWrapperClass { private DataObject data; public MyWrapperClass(DataObject data) { this.data = data; } public String doSomethingImportant() { ... version-specific logic ... } } This works well until I need to work on version 2.0 of our application. Now DataObject in the two versions are very similar, but not the same. This resulted in different sub classes of MyWrapperClass, which implement their own version-specific doSomethingImportant(). Still doing okay. But how does myDTO instantiate the appropriate version-specific MyWrapperClass? Hibernate is in turn instantiating MyDTO, so it's not like I can @Autowire a dependency in Spring. I would love to reuse MyDTO (and my dozens of other DTOs) for both versions of the tool, without having to duplicate the class. Don't repeat yourself, and all that. I'm sure there's a very simple pattern I'm missing that would help this. Any suggestions?

  • R: how to make a unique set of names from a vector of strings?

    - by Mike Dewar
    Hi, I have a vector of strings. Check out my vector, it's awesome: > awesome [1] "a" "b" "c" "d" "d" "e" "f" "f" I'd like to make a new vector that is the same length as awesome but where, if necessary, the strings have been uniqueified. For example, a valid output of my desired function would be > awesome.uniqueified [1] "a" "b" "c" "d.1" "d.2" "e" "f.1" "f.2" Is there an easy, R-thonic and beautiful way to do this? I should say my list in real life (it's not called awesome) contains 25000ish mircoarray probeset identifiers. I'm always nervous when I embark on writing little generic functions (which I'm sure I could do) as I'm sure some R guru has come across this problem in the past, nailed it with some incredible algorithm that doesn't even have to store more than half an element in the vector. I'm just not sure what they might have called it. Probably not uniqueify.

  • Facebook Connect in Silverlight

    - by Mike Pateras
    Is there a good way to get Facebook Connect onto a Silverlight page? All I really need is simple authorization/registration. I've looked into the facebook developer toolkit, but the documentation is more or less non-existent for Silverlight, and I didn't really get anywhere with it. Is there a good tutorial or a working library for adding Facebook Connect into a Silverlight app? Or is the best way to run Silverlight in Windowwless mode with HTML overlayed on top?

  • CSS of iFramed page not being applied properly

    - by Mike E.
    My company has purchased a third-party package with a built-in customer facing web portal, and I'm being tasked with integrating it into our site. Unfortunately, the web portal does not look great, and we have absolutely no control over how it looks (other than asking the vendor for changes - $$). In order to make it look somewhat like the rest of our site, I've stuck it in an iFrame (I'm not thrilled about this either) to put our logo and top navigation on it. Please note, I am not attempting to manipulate the iframed page in any way. Firefox handles this just fine, but in IE7 and IE8, not all of the CSS is being applied properly when the application's pages are displayed in the iFrame. Specifically, it should be applying a font-family of Arial to all TDs, but some text inside TDs are not being displayed as Arial. Any ideas as to what is going on? This only happens when the pages are viewed inside the iFrame. Outside the iFrame, the CSS is applied as it should be. I'm guessing we're going to have to get our vendor to make some changes, but I'd love to know why the iFrame is impacting the page like this. Thanks!

  • J2SE Client Server App: Client calls RMI method. Server handles RMI method and returns, but Client

    - by Mike
    J2SE Client Server App: Client calls RMI message. Server handles RMI method and returns, but Client never receives it. Any ideas how this could happen? Our attempted solution is to set client read timeouts and come up with a framework for resending requests or otherwise handling those failures gracefully. But really, I'd like to know any root causes for how this might happen rather than addressing the symptoms.

  • Convert integer to equivalent number of blank spaces.

    - by mike
    I was wondering what the easiest way is to convert an integer to the equivalent number of blank spaces. I need it for the spaces between nodes when printing a binary search tree. I tried this `int position = printNode.getPosition(); String formatter = "%1"+position+"s%2$s\n"; System.out.format(formatter, "", node.element);` But I am getting almost 3 times as many spaces compared to the int value of position. I'm not really sure if I am formatting the string right either. Any suggestions would be great! If it makes it clearer, say position = 6; I want 6 blank spaces printed before my node element.

  • php $_POST array empty upon form submission...

    - by Mike D
    Hi folks, I'm baffled on this after much googling. This issue is simple, I have a custom CMS i've built that works perfectly on my dev box (Ubuntu/PHP5+/MySQL5+). I just moved it up to the production box for my client and now all form submissions are showing up as empty $_POST arrays. I found a trick to verify the data is actually being passed using "file_get_contents('php://input');" and the data is showing up fine there -- the $_POST/$_REQUEST arrays are always empty. I've also verified the content-type headers are correct as well via firebug (application/x-www-form-urlencoded; charset=utf-8). This issue is happening regardless of whether a form is submitting via AJAX or a regular form submit. Any help is greatly appreciated!

  • Stubborn UIButton

    - by Mike
    I have a UIButton that is supposed to be disabled during certain phases. So, when this happens I do [myButton setEnabled:NO]; This is perfect because the button stays grayed and if clicked will not trigger its action, but... when the button is clicked even grayed, it enables again and a second click will trigger its actions (???????!!!!!!!!!!). How can that be? If the button is disabled it is supposed to be "part of the background", i.e., an image without any action. I have tried to make the button vanish using alpha but even if you click on the empty spot, it reappears after the first click and then can trigger actions after the second click... (????) Am I missing something?

  • Adding Controls Programatically

    - by Mike Keller
    I have a page I need to build out where depending on the selection the user made on a form on the page prior it displays a different set of questions for them to answer. So say the user selects Reason A from the form on page edit, then it needs to display Questions 1 and 2 on page edit_confirmation. But if they select Reason B then it needs to display Questions 3 and 4. I'm grabbing the reason code from the query string and have a switch statement set up, but I can't find anywhere how to output different controls. If Questions 1 and 2 are supposed to show up, one could be a text box and the other a checkbox, but if questions 3 and 4 are supposed to show up one may need to be a dropdown list and a checkbox.

  • iPhone: Waiting until selectrow animation finishes before pushing viewcontroller?

    - by Mike
    My code looks like this: NSIndexPath *ip = [NSIndexPath indexPathForRow:15 inSection:0]; [[self tableView] selectRowAtIndexPath:ip animated:YES scrollPosition:UITableViewScrollPositionMiddle]; // Pause needed here until animation finishes [[self navigationController] pushViewController:secondView animated:YES]; Right now it animates the scroll/selection of the row and pushes the view controller at the same time. What I would like it to do is wait until it finishes the scroll/selection and then push the view controller. Is there any possible way of doing this? Thanks

  • cocoa - referencing a method on the parent

    - by Mike
    I had a method on my main view controller named "calculateThis". This method was run, obviously, as int newValue = [self calculateThis:myVariable]; when I run it from inside the view controller. Then I created a static class and I need to run this method from there. How do I reference this method from that class using just relative references, as super, superview, delegate, etc. I cannot use the class name defined on the delegate because this static class is used in several apps of mine.

  • Client Side Only Cookies

    - by Mike Jones
    I need something like a cookie, but I specifically don't want it going back to the server. I call it a "client side session cookie" but any reasonable mechanism would be great. Basically, I want to store some data encrypted on the server, and have the user type a password into the browser. The browser decrypts the data with the password (or creates and encrypts the data with the password) and the server stores only encrypted data. To keep the data secure on the server, the server should not store and should never receive the password. Ideally there should be a cookie session expiration to clean up. Of course I need it be available on multiple pages as the user walks through the web site. The best I can come up with is some sort of iframe mechanism to store the data in javascript variables, but that is ugly. Does anyone have any ideas how to implement something like this? FWIW, the platform is ASP.NET, but I don't suppose that matters. It needs to support a broad range of browsers, including mobile. In response to one answer below, let me clarify. My question is not how to achieve the crypto, that isn't a problem. The question is where to store the password so that it is persistent from page to page, but not beyond a session, and in such a way that the server doesn't see it.
