• iqueryable select/where not working

  - by Steve

  I have two tables Boxer and Prospect. Boxers has general stuff like name and and dob etc and a BoxerId While Prospect contains only one value (at the moment) which is a boxerId. If a boxer is a prospect(up and coming boxer) there Id will be in the prospect table. This works fine but now I want to select all boxers that are prospects public static IQueryable<Boxer> IsProspect(this IQueryable<Boxer> query) { //this does not filter down to only prospects!!! return query.Where(x => x.Prospect != null); } This is the function I call using: var repository = GetRepository<Boxer>(); var boxers = repository.Query().IsProspect(); I would hope this would filter my collection of all boxers down to just boxers that are prospects! Oddly it doesnt filter it but if i hover over my boxers object and look at each boxer during debugging I can see "IsProspect" true or false correctly

• jQuery Find Previous Table Row that has a Cell with a Specific Class

  - by Huy Tran

  Hello All, Suppose I have a table like so: <table> <tr><td class="this-is-a-label">Label Cell</td></tr> <tr><td>Detail 1</td></tr> <tr><td class="selected">Detail 2</td></tr> </table> I want to be able to grab the previous "Label Cell" from the "Selected" cell. My jQuery script should be something like: $('.selected').each(function() { var label = $(this).parent().prev('tr td.this-is-a-label'); //... do what I need with the label ... }); But it's not working. Does anyone have any suggestions? Thanks.

• What is the difference between "a is b" and "id(a) == id(b)" in Python?

  - by bp

  The id() inbuilt function gives... an integer (or long integer) which is guaranteed to be unique and constant for this object during its lifetime. The is operator, instead, gives... object identity So why is it possible to have two objects that have the same id but return False to an is check? Here is an example: >>> class Test(): ... def test(): ... pass >>> a = Test() >>> b = Test() >>> id(a.test) == id(b.test) True >>> a.test is b.test False A more troubling example: (continuing the above) >>> b = a >>> b is a True >>> b.test is a.test False >>> a.test is a.test False

• Recording app sound in iphone

  - by user292127

  Hi, I am developing a music mixing app in iphone. It'll mix the music and user can compose a new music from it. I need to record this final music. I had used AVAudiorecorder to record this one. But no change. It can record sound from microphone but I need to record app sound. I had used audio queue call back function to record the audio. But when app runs I can hear the audio from my app and I couldn't hear any sound from recorded audio. There is no problem with recording since I can hear the audio recorded through microphone. But I need an offline recorder which can record the audio output of iphone, rather than the audio input through microphone. I need a recorder which can record audio using ipod touch (no microphone). Any help?

• Capturing clicks even when stopPropagation has been called (ie by 3rd party code)?

  - by josh

  I want to detect any click that happens on a page (to close a custom context menu). I'm using jQuery and trying to do $(document).click(function(){ ...close my context menu ... }); However, I'm using some code that calls evt.stopPropagation() in the click handlers for certain elements on the page, and those clicks aren't making it up to my top-level handler. Is there any way of capturing those clicks? Can be jQuery or not jQuery, as long as it works cross-browser.

• Jquery li element id

  - by Gazler

  Hi, I am using a jquery contextmenu plugin for right click menus which I am trying to add to each li element of an unordered list with the ID mailbox. The code I have is: $("#mailbox > li").contextMenu('myMenu1', { bindings: { 'open': function(t) { alert('Trigger was '+t.id+'\nAction was Open'); } //CODE SNIPPED }); My assumption is that this should alert the id of the list element that the contextMenu was called from, however it is returning an empty string. Am I accessing/assigning these correctly? t is an object HTMLLIElement in the context above by the way. Cheers, Gazler.

• Hide or display a button according to row count of a table

  - by kawtousse

  Hi, i have a HTML table and a button send. First of all the send button must have this style: style.display="none". But if the table has at least one row the button should be displayed (block/inline); I still have no idea how to relate between the table and the button. I try to use JavaScript but i should think about a function and I don't found any of it to apply at type table. Thinking about CSS still also hard since I cannot find a relation between the table and the button.

  I am creating a pricing program. I need to calculate the amounts according to the current tax list in the US (in various places).

  - by smoove666

• jQuery variable iteration with .each()

  - by user1143357

  My code needs to capture the 'src' of an image in a variable. It then needs to insert this variable into a 'href' tag on a link which surrounds the image. My code is as follows: $('.fancybox-image-li img').each(function(test) { var test = $(this).attr("src"); $('.fancybox-image-link').attr('href', ''+test+''); }); Unfortunately what seems to be happening is the 'test' var is only getting the attribute of the last img and then inserting this into all the 'href' attributes. Any ideas how I can get the variable to change per image. Cheers!

• Thumbnailing and then Saving as a Blob with PHP in Wordpress

  - by Parris

  The below code seems like it should work; however, the blob in the database only contains 0 after the function is run. Does the below code look accurate? If not how can I fix it? $tmpName = $_FILES['picture']['tmp_name']; $fp = fopen($tmpName, 'r'); $binary = fread($fp, filesize($tmpName)); fclose($fp); $originalImage = imagecreatefromstring($binary); $tempImage = imagecreate(100,100); imagecopyresized($tempImage,$originalImage,0,0,0,0,100,100); ob_start(); imageJPEG($tempImage); $thumbnail = ob_get_contents(); ob_end_clean(); $wpdb->query("UPDATE ".$wpdb->prefix."items SET picture = $thumbnail WHERE id=$id'"); Thank :)!

• Should I pointer-cast from a private derived class to its base class?

  - by skydoor

  I found this from C++FAQ Generally, No. From a member function or friend of a privately derived class, the relationship to the base class is known, and the upward conversion from PrivatelyDer* to Base* (or PrivatelyDer& to Base&) is safe; no cast is needed or recommended. However users of PrivatelyDer should avoid this unsafe conversion, since it is based on a private decision of PrivatelyDer, and is subject to change without notice. How to understand the above words? I don't think the explanation is correct or accurate. I have a code like this class A{ }; class B: private A{ }; int main(){ B *b = new B(); A *a = new A(); a = b; //wrong a = (A*)b; //right }

• jquery ajax sucess - possible to return JSON instead of string?

  - by Haroldo

  To return an error from a $.ajax call, there's gotta be a better way than echoing an error in the ajax.php file and then trimming it! this seems very clumsy and in-robust: success: function(e){ var e = trim(e); if(e == 'SUCCESS') {alert('your password has been changed!');} if(e == 'ERROR1') {alert('please fill in all inputs!');} if(e == 'ERROR2') {alert('password incorrect!');} if(e == 'ERROR3') {alert('change failed!');} } what should i be doing instead?!

• how-to initialize 'const std::vector<T>' like a c array

  - by vscharf

  Is there an elegant way to create and initialize a const std::vector<const T> like const T a[] = { ... } to a fixed (and small) number of values? I need to call a function frequently which expects a vector<T>, but these values will never change in my case. In principle I thought of something like namespace { const std::vector<const T> v(??); } since v won't be used outside of this compilation unit.

• How to encode content to send them via jquery to a php file?

  - by phpheini

  I am trying to send a form to a php file via jquery. The problem is, that the content, which has to be sent to the php file, contains slashes (/) since there is bb code inside. So I tried the following: $.ajax( { type: "POST", url: "create.php", data: "content=" + encodeURIComponent(content), cache: false, success: function(message) { $("#somediv").html(message); } }); In the php file I use rawurldecode to decode the content and get my bb codes back which I can then transform into html. The problem is as soon as I put the encodeURIComponent() it will ouput: [object HTMLTextAreaElement] What does that mean, where is my mistake? Thanks for your help! phpheini

• compare date split across colums

  - by alex-tech

  Greetings. I am querying tables from Microsoft SQL 2008 which have date split across 3 columns: day, month and year. Unfortunately, I do not have control over this because data is coming in to the database daily from a 3rd party source in that format. I need to add between to a where clause so user can pull records within a range. Would be easy enough if date was in a single column but finding it nearly impossible when its split across three columns. To display the date, I am doing a CAST( CAST(year as varchar(4)) + '-' + CAST(month as varchar(2)) + '-' + CAST(day as varchar(2)) as date) AS "date"` in a select. I tried to put it as a parameter for datediff function or just the regular between but get no results. Thanks for any help.

• Going from numpy array to itk Image

  - by tkerwin

  I have a numpy array and want to convert it into an ITK image for further processing. How do I do this without using the PyBuffer extension to WrapITK. I can't use that because I get a bunch of errors when compiling: .../ExternalProjects/PyBuffer/itkPyBuffer.txx: In static member function ‘static PyObject* itk::PyBuffer<TImage>::GetArrayFromImage(TImage*) [with TImage = itk::Image<float, 2u>]’: .../ExternalProjects/PyBuffer/wrap_itkPyBufferPython.cxx:1397: instantiated from here .../ExternalProjects/PyBuffer/itkPyBuffer.txx:64: error: cannot convert ‘int*’ to ‘npy_intp*’ in argument passing I could use an idea about either how to fix the compilation errors or another way to convert my python objects.

• Generating data on unlevel background

  - by bluejay93

  I want to make an unlevel background and then generate some test data on that using Matlab. I was not clear when I asked this question earlier. So for this simple example for i = 1:10 for j = 1:10 f(i,j)=X.^2 + Y.^2 end end where X and Y have been already defined, it plots it on a flat surface. I don't want to distort the function itself, but I want the surface that it goes onto to be unlevel, changed by some degree or something. I hope that's a little clearer.

Looks right to me. mailreq.php include("mail.php"); $r = mymail("test","test"); mail.php function mymail($body, $reqtype) { //blah blah } EDIT: For some reason, this version of php doesn't see <? ?> as valid shorthand tags. I changed it to <?php ?> and it sees the functions now.
