  • Qt Direct Connection

    - by user152508
    Hello I have created Qt tree control( and its nodes ) in different thread than the main thread. In the main thread I want to show context menu for the clicked node, so I am connectiong the actions in the menu with appropriate slots in the main thread. The connect function returns true , but slot is never executed. If I explicitly say in connect function that this is Qt :: DirectConnection then everything works fine. Why is this ? I I create my tree in main thread, everything also works fine , without having to say that this is Qt::DirectConnection .

  • How to enable i18n from within setup_app in websetup.py ? (formatted resend)

    - by daniel
    From within the setup_app function (websetup.py) of a pylons i18n application, which is making use of a db, I was trying to initiate multilingual content to be inserted into the db. To do so the idea was something like: #necessary imports here def setup_app(command, conf, vars): .... for lang in langs: set_lang(lang) content=model.Content() content.content=_('content') Session.add(content) Session.commit() Unfortunately it seems that it doesn't work. the set_lang code line is firing an exception as follows: File ".. i18n/translation.py", line 179, in set_lang translator = _get_translator(lang, **kwargs) File ".. i18n/translation.py", line 160, in _get_translator localedir = os.path.join(rootdir, 'i18n') File ".. /posixpath.py", line 67, in join elif path == '' or path.endswith('/'): AttributeError: 'NoneType' object has no attribute 'endswith' Actually I'm even not sure it could be possible launching i18n mechanisms from within this setup_app function without an active request object. Anyone has tried some trick on a similar story ?

  • JqueryUI Tab Linking from Another Page

    - by pschorr
    I'm having some issues with jqueryui tabs and linking to certain tabs on another page. Basically, each page has tabs, and all are navigational via drop down at the top, with each 'tab' being available in the drop down. Currently I'm able to text-link, but only within the page I'm on, and I'm just lost on the getting it to work correctly from page to page. Here's what I currently got working with internal text link. $(function() { $("#tabs").tabs( {fx: { opacity: 'toggle' }, selected: 0} ); var $tabs = $('#tabs').tabs(); // first tab selected $('a.nutrlink').click(function() { // bind click event to link $tabs.tabs('select', 1); // switch to third tab return false; }); });

  • PHP: Mapped Network Drives

    - by Abs
    Hello all, I have mapped a network drive to a computer in my home network. Now I am trying to access it via PHP - I did this quick test: echo opendir('Z:\\'); This gives me: Warning: opendir(Z:\) [function.opendir]: failed to open dir: No error in C:\wamp\www\webs\tester-function.php on line 3 What have I done wrong here? I don't want my users typing in the UNC path so is there a way to get the UNC path for them and maybe that will work when I try to access it? This is possible in Microsoft languages but I am not sure how to get PHP to do this - maybe using a cmd.exe command? Please note, the mapped drive does exist as I can see it and I can access it. It also does not appear to be a permissions problem as I am assuming it would of complained about this IF it could access that drive...right? Thanks all for any help

  • Equivalence Classes LISP

    - by orcik
    I need to write a program for equivalence classes and get this outputs... (equiv '((a b) (a c) (d e) (e f) (c g) (g h))) => ((a b c g h) (d e f)) (equiv '((a b) (c d) (e f) (f g) (a e))) => ((a b e f g) (c d)) Basically, A set is a list in which the order doesn't matter, but elements don't appear more than once. The function should accept a list of pairs (elements which are related according to some equivalence relation), and return a set of equivalence classes without using iteration or assignment statements (e.g. do, set!, etc.). However, set utilities such as set-intersection, set-union and a function which eliminates duplicates in a list and built-in functions union, intersection, and remove-duplicates are allowed. Thanks a lot!

  • Unmangling the result of std::type_info::name

    - by terminus
    I'm currently working on some logging code that supposed to - among other things - print information about the calling function. This should be relatively easy, standard C++ has a type_info class. This contains the name of the typeid'd class/function/etc. but it's mangled. It's not very usefull. I.e. typeid(std::vector).name() returns "St6vectorIiSaIiEE". Is there a way to produce something usefull from this? Like 'std::vector' for the above example. If it only works for non-template classes, that's fine too. The sollution should work for gcc, but it would be better if I could port it. It's for logging so it's not so important that it can't be turned of, but it should be helpfull for debugging.

  • question about c++ template functions taking any type as long that type meets at least one of the re

    - by smerlin
    Since i cant explain this very well, i will start with a small example right away: template <class T> void Print(const T& t){t.print1();} template <class T> void Print(const T& t){t.print2();} This does not compile: error C2995: 'void Print(const T &)' : function template has already been defined So, how can i create a template function which takes any type T as long as that type has a print1 memberfunction OR a print2 memberfunction (no polymorphism) ?

  • How do I convert an arbitrary list of strings to a SQL rowset?

    - by Jim Kiley
    I have a simple list of strings, which may be of arbitrary length. I'd like to be able to use this list of strings as I would use a rowset. The app in question is running against SQL Server. To be clearer, if I do SELECT 'foo', 'bar', 'baz' I get 'foo', 'bar', and 'baz' as fields in a single row. I'd like to see each one of them as a separate row. Is there a SQL (or SQLServer-specific) function or technique that I'm missing, or am I going to have to resort to writing a function in an external scripting language?

  • update each recordset with datareader

    - by knittl
    hi, my situation is the following: i have a datareader and loop over all records returned by a select statement and then call a function with a value from that row. but now i need to update a column in each row, after the function has been called. using a separate update statement seems like a huge overkill. what's the best method to do so? i've heard about dataadapters and datasets—but the only thing i know is that they exist, not how to use them (properly) in this case. platform is c# with sql server

  • Select an entity according to a list of associated entities

    - by Maverickch
    I have the following database schema : Two tables, books and tags, with n-m relationship. Books - Tags We can have for example the book 1, with tags {A,B,C}, and book 2, with tags {A}. I would like to select the books according to a list of tags. For example : selected tags list : {A,B} - book 1 My idea was to use the MINUS SQL function, to subtract book tags list to the selected tags list, and return the book if the list was empty. Unfortunately, this SQL function is not supported by HQL. Any idea about that ?

  • How do would you use jQuery's .each() to apply the same script to each element with the same class?

    - by derekmx271
    I have a with multiple cart items listed. I have a "x-men logo" looking remove button that I want to fade-in next to the item when the customer hovers over a cart item. I had no issue getting this to work when there is only one item in the list. However, when there are multiple items in the cart, the jQuery operates funky. It still does the fade in, but only when I hover over the last item in the cart, and of course all of the "remove X" images become visible. Argh... So i searched around and think the .each() is my savior. I have been trying to get it to work, with no luck. My script just breaks when I attempt to implement it. Anyone have any pointers on this *.each() thing and how to implement it into my script?* I have tried putting a cartItem.each(function(){ around the mouseEnter/mouseLeave events (and used some $(this) selectors to make it "make sense") and that didn't do anything. Tried some other things as well with no luck... Here is the HTML (Sorry, there's a lot): <ul id="head-cart-items"> <!-- Item #1 --> <li> <!-- Item #1 Wrap --> <div class="head-cart-item"> <div class="head-cart-img" style='background-image:url("/viewimageresize.asp?mh=50&amp;mw=50&amp;p=AFE&amp;f=Air_Intakes_Magnum_FORCE_Stage-1_PRO_5R")'> </div> <div class="head-cart-desc"> <h3> <a href="/partdetails/AFE/Intakes/Air_Intakes/Magnum_FORCE_Stage-1_PRO_5R/19029">AFE Magnum FORCE Stage-1 PRO 5R Air Intakes</a> </h3> <span class="head-cart-qty">Qty: 1</span> <span class="head-cart-price">$195.00</span> <!-- Here is my Remove-X... --> <a class="remove-x" href='/cart//7806887'> <img src="/images/misc/remove-x.png"> </a> </div> </div> </li> <!-- Item #2 --> <li> <!-- Item #2 Wrap --> <div class="head-cart-item"> <div class="head-cart-img" style='background-image:url("/viewimageresize.asp?mh=50&amp;mw=50&amp;p=Exedy&amp;f=Clutch_Kits_Carbon-R")'> </div> <div class="head-cart-desc"> <h3> <a href="/partdetails/Exedy/Clutch/Clutch_Kits/Carbon-R/19684">Exedy Carbon-R Clutch Kits</a> </h3> <span class="head-cart-qty">Qty: 1</span> <span class="head-cart-price">$2,880.00</span> <!-- Here is my other Remove-X... --> <a class="remove-x" href='/cart//7806888'> <img src="/images/misc/remove-x.png"> </a> </div> </div> </li> </ul> And here is the jQuery... $(document).ready(function(){ var removeX = $(".remove-x"); var cartItem = $(".head-cart-item"); // Start with an invisible X removeX.fadeTo(0,0); // When hovering over Cart Item cartItem.mouseenter(function(){ // Fade the X to 100% removeX.fadeTo("normal",1); // On mouseout, fade it back to 0% $(this).mouseleave(function(){ removeX.fadeTo("fast",0); }); }); }); If you didn't see it, here is the "X" I am trying to fade... <!-- Here is my Remove-X... --> <a class="remove-x" href='/cart//7806887'> <img src="/images/misc/remove-x.png"> </a> Thanks for the help in advance.

  • JQuery Optimization: Is there any way to speed up the rendering of the FlexSelect control?

    - by Sephrial
    Greetings, I am new to jQuery, and I have a performance problem with the FlexSelect control where it takes about 5 seconds to render the dropdown control (in the renderDropdown() function). The dropdown list contains about 5000 element. I believe all the runtime is attributed to the following block of code: var list = this.dropdownList.html(""); $.each(this.results, function() { list.append($("<li/>").html(this.name)); }); Question: Are there any alternatives that would build this list of elements in a more inefficient manner?

  • Why are my JavaScript variables not persisting across functions?

  • Yii file upload issue

    - by user1289853
    Couple of months ago,I developed a simple app using YII,one of the feature was to upload file. The feature was working well in my dev machine,couple of days ago client found the file upload feature is not working in his server since deployment. And after that I test my dev machine that was not working too. My controller looks: public function actionEntry() { if (!Yii::app()->user->isGuest) { $model = new TrackForm; if (isset($_POST['TrackForm'])) { $entry = new Track; try { $entry->product_image = $_POST['TrackForm']['product_image']; $entry->product_image = CUploadedFile::getInstance($model, 'product_image'); if ($entry->save()) { if ($entry->product_image) { $entry->product_image->saveAs($entry->product_image->name, '/trackshirt/uploads'); } } $this->render('success', array('model' => $model)); // redirect to success page } } catch (Exception $e) { echo 'Caught exception: ', $e->getMessage(), "\n"; } } else { $this->render('entry', array('model' => $model)); } } } Model is like below: <?php class Track extends CActiveRecord { public static function model($className=__CLASS__) { return parent::model($className); } public function tableName() { return 'product_details'; } } My view looks: <?php $form = $this->beginWidget('CActiveForm', array( 'id' => 'hide-form', 'enableClientValidation' => true, 'clientOptions' => array( 'validateOnSubmit' => true, ), 'htmlOptions' => array('enctype' => 'multipart/form-data'), )); ?> <p class="auto-style2"><strong>Administration - Add New Product</strong></p> <table align="center" style="width: 650px"><td class="auto-style3" style="width: 250px">Product Image</td> <td> <?php echo $form->activeFileField($model, 'product_image'); ?> </td> </tr> </table> <p class="auto-style1"> <div style="margin-leftL:-100px;"> <?php echo CHtml::submitButton('Submit New Product Form'); ?> </div> <?php $this->endWidget(); ?> Any idea where is the problem?I tried to debug it but every time it returns Null.

  • Can I use this Ajax script to communicate and exchange data between client and server?

    - by lala
    This block of code is for client.html (it is located in this www.client.com/client.html) - client side. The I have the code below that goes something like this: ajaxRequest.open("GET", "http://www.server.com/ajax.php", true); This is how I call the file ajax.php located in the server. Unfortunately I have no luck at all. It cannot connect to the server I'm calling. BTW, the ips /test site I've been using are all no restrictions, and is accessible to all. However, I tried to simulate by putting both client.html and ajax.php in same site and it works well. So my question is does this script works only if you are in same site? or does it work also in client-server scenario? What else do I have to do in order to make this work? //client.html <script language="javascript" type="text/javascript"> <!-- //Browser Support Code function ajaxFunction(){ var ajaxRequest; // The variable that makes Ajax possible! try{ // Opera 8.0+, Firefox, Safari ajaxRequest = new XMLHttpRequest(); } catch (e){ // Internet Explorer Browsers try{ ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try{ ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e){ // Something went wrong alert("Your browser broke!"); return false; } } } // Create a function that will receive data sent from the server ajaxRequest.onreadystatechange = function(){ if(ajaxRequest.readyState == 4){ document.myForm.time.value = ajaxRequest.responseText; } } ajaxRequest.open("GET", "http://www.server.com/ajax.php", true); ajaxRequest.send(null); } //--> </script> <form name='myForm'> Name: <input type='text' onChange="ajaxFunction();" name='username' /> <br /> Time: <input type='text' name='time' /> </form> </body> </html> // ajax.php <?php echo date("H:i:s"); ?>

  • Can a process have two pid's?

    - by limp_chimp
    I'm studying computer systems and I've made this very simple function which uses fork() to create a child process. fork() returns a pid_t that is 0 if it's a child process. But calling the getpid() function within this child process returns a different, nonzero pid. In the code I have below, is newPid only meaningful in the context of the program, and not to the operating system? Is it possibly only a relative value, measured against the pid of the parent? #include <stdio.h> #include <unistd.h> #include <sys/types.h> #include <string.h> #include <errno.h> #include <stdlib.h> void unixError(char* msg) { printf("%s: %s\n", msg, strerror(errno)); exit(0); } pid_t Fork() { pid_t pid; if ((pid = fork()) < 0) unixError("Fork error"); return pid; } int main(int argc, const char * argv[]) { pid_t thisPid, parentPid, newPid; int count = 0; thisPid = getpid(); parentPid = getppid(); printf("thisPid = %d, parent pid = %d\n", thisPid, parentPid); if ((newPid = Fork()) == 0) { count++; printf("I am teh child. My pid is %d, my other pid is %d\n", getpid(), newPid); exit(0); } printf("I am the parent. My pid is %d\n", thisPid); return 0; } Output: thisPid = 30050, parent pid = 30049 I am the parent. My pid is 30050 I am teh child. My pid is 30052, my other pid is 0 Lastly, why is the child's pid 2 higher than the parent's, and not 1? The difference between the main function's pid and its parent is 1, but when we create a child it increments the pid by 2. Why is that?

  • Can not recognize pdf scanned page with greek words by using PB , EZTWAIN and TOCR 3.0

    Hi, Iam using PB 10.5.2 and EZTwain 3.30.0.28, XDefs 1.36b1 by Dosadi for scanning. Also Iam using the TOCR 3.0 for OCR management. In a function we use the following among all others : ... Long ll_acquire (as_path_filename is a function argument) ... ... TWAIN_SetAutoOCR(1) ll_acquire = TWAIN_AcquireMultipageFile(0, as_path_filename) the problem is that the scanned pdf page has latin (english) and greek words. The English characters are searched quite precisely but the greek don't at all. Do you think this that this has to do with the TOCR software. I just want to search AND for greek words Thanks in advance

  • jQuery access each matched element from '.find' by an index

    - by GHarping
    Using jQuery's .find() method to return a set of elements, I am trying to access items in the returned set by their order in that set. For example, a table with two rows and in each row a select box and two text input fields, accessed with the following: $('table#tbl').find('tr.row').each(function(i) { }); To get the first element I would have thought I could use $('table#tbl').find('tr.row').each(function(i) { alert( $(this).find(':input').get(1).val() ); }); And variations of the above, but apparently this doesn't work. Could anyone suggest the correct method to access item x of n elements returned?

  • Access to bytes array of a Bitmap

    - by Deulis
    1- In Windows CE, I have a Bitmap object in C#. 2- I have a C function in an extern dll that expects as parameters the pointer to a bytes array that represents an image in RGB565 format, width and height. This function will draw on this array of bytes. So I need to pass the byte array pointer of the Bitmap object, but I can find a practical way to get this pointer. One way is convert this Bitmap into a bytes array using a memory stream or something else, but it will create a new bytes array, so I will keep in memory both object, the Bitmap and the bytes array, but I don’t want it because the few available memory, that’s why I need to access to the bytes array of the bitmap object, not create a new bytes array. Anyone can help me?

  • find lowest neighbor matlab

    - by user1812719
    I am trying to write a function [offset,coffset]=findLowNhbr(map) that for each pixel in a map finds the eight neighbors to the pixel, and returns two matrices with both the row and column offsets to the lowest neighbor (uses the numbers -1, 0 and 1). Border pixels are given 0 offsets for both the row and column, since they do not have neighbors. Here is what I think the general plan for this function should be: For each point, find the eight nearest neighbors. If the neighbor is lower than the point, return -1 If the neighbor is at the same elevation as the point, return 0 If the neighbor is higher than the point, return +1 Store these offsets in two matrices. I am at a complete loss as to where to start, so any advice or questions are welcome!
