  • popup panel that docks to the bottom of the screen

    - by Michael Wiles
    How do I create a pop panel that docks to the bottom of the screen... The way that I'm doing this is by setting the styling as such: bottom: 10px; position: absolute; This will always set the panel to 10 px from the bottom of the browser window. The problem is that gwt (or gwtp for that matter) is insisting on setting the right and the top of the panel and thus overriding my styling. If I use chrome's element explorer and disable the right and top style rules I get the correct behaviour so one way of doing it is somehow disabling gwt setting of the location of the panel on the screen...?

  • Getting the first of a GROUP BY clause in SQL

    - by Michael Bleigh
    I'm trying to implement single-column regionalization for a Rails application and I'm running into some major headaches with a complex SQL need. For this system, a region can be represented by a country code (e.g. us) a continent code that is uppercase (e.g. NA) or it can be NULL indicating the "default" information. I need to group these items by some relevant information such as a foreign key (we'll call it external_id). Given a country and its continent, I need to be able to select only the most specific region available. So if records exist with the country code, I select them. If, not I want a records with the continent code. If not that, I want records with a NULL code so I can receive the default values. So far I've figured that I may be able to use a generated CASE statement to get an arbitrary sort order. Something like this: SELECT *, CASE region WHEN 'us' THEN 1 WHEN 'NA' THEN 2 ELSE 3 END AS region_sort FROM my_table WHERE region IN ('us','NA') OR region IS NULL GROUP BY external_id ORDER BY region_sort The problem is that without an aggregate function the actual data returned by the GROUP BY for a given row seems to be untameable. How can I massage this query to make it return only the first record of the region_sort ordered groups?

  • Password test in 1st Tab.m to load a loginView gives class error?

    - by Michael Robinson
    I have a name and password in NSUserDefaults for login. I have this in my 1stTab View.m class to test for presence and load a login/signup loginView.xib modally if there is no password or name stored in the app. Here is the pulling of the defaults: -(void)refreshFields { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; usernameLabel.text = [defaults objectForKey:kUsernameKey]; passwordLabel.text = [defaults objectForKey:kPasswordKey]; { Here is the Test: - (void)viewDidAppear:(BOOL)animated { [self refreshFields]; [super viewDidAppear:animated]; if ([usernameLabel.text length] == 0 || [passwordLabel.text length] == 0) { LoginViewController * vc = [[[LoginViewController alloc] initWithNibName:@"LoginView" bundle:nil] autorelease]; [self presentModalViewController:vc animated: false]; } else { [[self tableView ]reloadData]; } } Thanks in advance, I'm getting this error in the console: * Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key usernameLabel.'

  • Web Audio API and mobile browsers

    - by Michael
    I've run into a problem while implementing sound and music into an HTML game that I'm building. I'm using the Web Audio API, loading all the sound files with XMLHttpRequests and decoding them into an AudioBufferSourceNode with AudioContext.prototype.decodeAudioData(). It looks something like this: var request = new XMLHttpRequest(); request.open("GET", "soundfile.ogg", true); request.responseType = "arraybuffer"; request.onload = function() { context.decodeAudioData(request.response) } request.send(); Everything plays fine, but on mobile the decodeAudioData takes an absurdly long time for the background music. I then tried using AudioContext.prototype.createMediaElementSource() to load the music from an HTML Audio object, since they support streaming and don't have to load the whole file into memory at once. It looked something like this: var audio = new Audio('soundfile.ogg'); var source = context.createMediaElementSource(audio); var mainVolume = context.createGain(); source.connect(mainVolume); mainVolume.connect(context.destination); This loads much faster, but the audio volume isn't affected by the gain node. Works fine on desktop, so I'm assuming this is a bug/limitation of mobile Chrome (testing on Android). Is there actually no good, well-performing way to handle sound on mobile browsers or am just I doing something stupid?

  • Acl mechanism for JSF

    - by michael lucas
    Is there some ready-to-use ACL mechanism for JSF? I know JBoss Seam comes with something like that, but switching to JBoss Seam is not an option in my case. What I need is to easily define which pages given user is allowed to see and which actions to invoke.

    I am looking to add a custom message before listing my errors for a login page: "Oops, you forgot to enter the following:" + "Username", "Password" (if both not entered) or "Oops, you forgot to enter the following:" + "Username" (if just username not entered) $(document).ready(function(){ $("#loginForm").validate({ errorLabelContainer: $('#RegisterErrors'), messages: { username: "Username", password: "Password" } }); }); With this in my HTML <div id="RegisterErrors">

  • Cakephp Auth Flash Messages losing style

    - by Michael
    My Auth flash messages were working earlier -- a bright green background with text in it, such as "You have successfully logged out". However, I have made quite a few changes to the site since then, and this green background has disappeared. What are the possible causes of this? (I've run my CSS through a validator -- so that doesn't seem to be the issue). Any other ideas? Thanks!

  • Is There a Good Pattern for Creating a Unique Id based on a Type?

    - by Michael Kelley
    I have a template that creates a unique identifier for each type it is instanced. Here's a streamlined version of the template: template <typename T> class arType { static const arType Id; // this will be unique for every instantiation of arType<>. } // Address of Id is used for identification. #define PA_TYPE_TAG(T) (&arType<T >::Id) This works when you have an executable made purely of static libraries. Unfortunately we're moving to an executable made up of dlls. Each dlls could potentially have its own copy of Id for a type. One obvious solution is to explicitly instantiate all instances of arType. Unfortunately this is cumbersome, and I'd like to ask if anyone can propose a better solution?

  • php preg_replace, regexp

    - by Michael
    I'm trying to extract the postal codes from yell.com using php and preg_replace. I successfully extracted the postal code but only along with the address. Here is an example $URL = "http://www.yell.com/ucs/UcsSearchAction.do?scrambleSeed=17824062&keywords=shop&layout=&companyName=&location=London&searchType=advance&broaderLocation=&clarifyIndex=0&clarifyOptions=CLOTHES+SHOPS|CLOTHES+SHOPS+-+LADIES|&ooa=&M=&ssm=1&lCOption32=RES|CLOTHES+SHOPS+-+LADIES&bandedclarifyResults=1"; //get yell.com page in a string $htmlContent = $baseClass-getContent($URL); //get postal code along with the address $result2 = preg_match_all("/(.*)/", $htmlContent, $matches); print_r($matches); The above code ouputs something like Array ( [0] = Array ( [0] = 7, Royal Parade, Chislehurst, Kent BR7 6NR [1] = 55, Monmouth St, London, WC2H 9DG .... the problem that I have is that I don't know how to extract the the postal code because it doesn't have an exact number of digits (sometimes it has 6 digits and sometimes has only 5 times). Basically I should extract the lasted 2 words from each array . Thank you in advance for any help !

  • SSH is looking in the wrong place for the public/private key pair on Windows

    - by Michael Morisy
    I'm trying to configure GIT on my Windows XP machine, but SSH keeps creating and looking for the public/private key pair in non-sensical places, e.g. /.ssh/id_rsa Is there a configuration file in the GIT Installation for Windows where I can switch this to my home directory, or another user defined place? By default, it offers to create new key pairs at //.ssh/id_rsa but that gives me the error "Could not create directory '//.ssh'." And when I'm able to find a directory I can create it in, GIT won't look there.

  • PHP - error when insert date into MySQL

    - by Michael Mao
    Hello everyone: I've got a typical problem when trying to insert a date into MySQL. The column defined in MySQL is of type DATE. My PHP version is 5.3.0 Apart from this date-related issue, the rest of my code works just fine. And this is my PHP script to do this: $tablename = BOOKS_TABLE; $insert = mysql_query("INSERT INTO $tablename (barcode, book_name, volume_num,". " author, publisher, item_type, buy_price, buy_date) VALUES ". "(". "'" . $barcode . "', ". "'" . $bookname . "', ". "'" . $volumenum . "', ". "'" . $author . "', ". "'" . $publisher . "', ". "'" . $itemtype . "', ". "'" . $buyprice . "', ". "'" . getMySQLDateString($buydate). //"'STR_TO_DATE('".$buydate ."', '%d/%m/%Y'))'". //nothing changes in MySQL ")"); And this is the faulty function : function getMySQLDateString($buydate) //typical buydate : 04/21/2009 { $mysqlDateString = date('Y-m-d H:i:s', $strtotime($buydate)); return $mysqlDateString; } The first commented out line wouldn't do anything, the script is executed with no error, however, there is nothing changed in datebase after this. The current approach will cause a Fatal error saying function name must be a string in this line. Actually I followed this thread on SO, but just cannot pass the date into MySQL... Can anyone help me figure out which part is not right? How would you do it, in this case, to get it right? Sorry about such a journeyman-like question, thanks a lot in advance.

  • Return specific HREF attribute using Xpath query

    - by Michael Pasqualone
    Having a major brain freeze, I have the following chunk of code: // Get web address $domQuery = query_HtmlDocument($html, '//a[@class="productLink"]'); foreach($domQuery as $rtn) { $web = $rtn->getAttribute('href'); } Which obviously gets the entire href attribute, however I only want 1 specific attribute within the href. I.e. If the href is: /website/product1234.do?code=1234&version=1.3&somethingelse=blaah I only want to return the variable for "version", so wish to only return "1.3" in my example. What's most efficient way to do this?

  • Distance between hyperplanes

    - by michael dillard
    I'm trying to teach myself some machine learning, and have been using the MNIST database (http://yann.lecun.com/exdb/mnist/) do so. The author of that site wrote a paper in '98 on all different kinds of handwriting recognition techniques, available at http://yann.lecun.com/exdb/publis/pdf/lecun-98.pdf. The 10th method mentioned is a "Tangent Distance Classifier". The idea being that if you place each image in a (NxM)-dimensional vector space, you can compute the distance between two images as the distance between the hyperplanes formed by each where the hyperplane is given by taking the point, and rotating the image, rescaling the image, translating the image, etc. I can't figure out enough to fill in the missing details. I understand that most of these are indeed linear operators, so how does one use that fact to then create the hyperplane? And once we have a hyperplane, how do we take its distance with other hyperplanes?

  • ASP MVC dynamic fields in editor

    - by Michael Pardo
    I have a form which will include some optional questions that need to asked of the user. In my model it may look like pubic Dictionary<String, String> Questions { get; set; } where the key is the label and value is the text box. How can I create and populate controls for this? I'm new to ASP MVC, but it makes sense that something like this would be built in. Is there a built in way to do this, or do I have to implement it myself? It seems like there should be a helper for it, since you don't really want to put this kind of code in the view. I've tried Html.EditorFor(model => model.Questions); but it just spits out "[key, value]" to the view.

  • Incorrect emacs indentation in a C++ class with DLL export specification

    - by Michael Daum
    I often write classes with a DLL export/import specification, but this seems to confuse emacs' syntax parser. I end up with something like: class myDllSpec Foo { public: Foo( void ); }; Notice that the "public:" access spec is indented incorrectly, as well as everything that follows it. When I ask emacs to describe the syntax at the beginning of the line containing public, I get a return of: ((label 352)) If I remove the myDllSpec, the indentation is correct, and emacs tells me that the syntax there is: ((inclass 352) (access-label 352)) Which seems correct and reasonable. So I conclude that the syntax parser is not able to handle the DLL export spec, and that this is what's causing my indentation trouble. Unfortunately, I don't know how to teach the parser about my labels. Seems that this is pretty common practice, so I'm hoping there's a way around it.

  • How to extract ALL typedefs and structs and unions from c++ source

    - by Michael Wells
    I have inherited a Visual Studio project that contains hundreds of files. I would like to extract all the typedefs, structs and unions from each .h/.cpp file and put the results in a file). Each typdef/struct/union should be on one line in the results file. This would make sorting much easier. typdef int myType; struct myFirstStruct { char a; int b;...}; union Part_Number_Serial_Number_Part_2_Response_Message_Type {struct{Message_Response_Head_Type Head; Part_Num_Serial_Num_Part_2_Report_Array Part_2_Report; Message_Tail_Type Tail;} Data; BYTE byData[140];}myUnion; struct { bool c; int d;...}mySecondStruct; My problem is, I do not know what to look for (grammar of typedef/structs/unions) using a regular expression. I cannot believe that nobody has done this before (I googled and have not found anything on this). Does anyone know the regular expressions for these? (Note some are commented out using // others /* */) Or a tool to accomplish this. Edit: I am toying with the idea of autogenerating source code and/or dialogs for modifying messages that use the underlying typedef/struct/union. I was going to use the output to generate an XML file that could be used for this reason. The source for these are in C/C++ and used in almost all my projects. These projects are usually NOT in C/C++. By using the XML version I would only need to update/add the typedef/struct/union only in one place and all the projects would be able to autogen the source and/or dialogs.

  • Is it safe to call a function to intialize a class in a ctor list?

    - by Michael Dorgan
    I have Angle class that I want initialized to a random value. The Angle constructor can accept an int from a random() function. Is it safe to place this call in the ctor list: foo::foo() : Angle(random(0xFFFF)) {...} or do I have to do it in the body of the constructor? foo::foo() { Angle = Angle(random(0xFFFF)); ...} If it matters, the foo class is derived from another class and does have virtual methods. In addition, no exception handling is allowed in our app.
