  • Advanced ASP.NET Gridview Layout

    - by chief7
    So i had a feature request to add fields to a second table row for a single data row on a GridView. At first, I looked at extending the functionality of the GridView but soon realized this would be a huge task and since I consider this request a shim for a larger future feature decided against it. Also want to move to MVC in the near future and this would be throw away code. So instead I created a little jquery script to move the cell to the next row in the table. $(document).ready(function() { $(".fieldAttributesNextRow").each(function() { var parent = $(this).parent(); var newRow = $("<tr></tr>"); newRow.attr("class", $(parent).attr("class")); var headerRow = $(parent).parent().find(":first"); var cellCount = headerRow.children().length - headerRow.children().find(".hide").length; newRow.append($(this).attr("colspan", cellCount)); $(parent).after(newRow); }) }); What do you think of this? Is this a poor design decision? I am actually quite pleased with the ease of this solution. Please provide your thoughts.

  • What's your preferred pointer declaration style, and why?

    - by Owen
    I know this is about as bad as it gets for "religious" issues, as Jeff calls them. But I want to know why the people who disagree with me on this do so, and hear their justification for their horrific style. I googled for a while and couldn't find a style guide talking about this. So here's how I feel pointers (and references) should be declared: int* pointer = NULL; int& ref = *pointer; int*& pointer_ref = pointer; The asterisk or ampersand goes with the type, because it modifies the type of the variable being declared. EDIT: I hate to keep repeating the word, but when I say it modifies the type I'm speaking semantically. "int* something;" would translate into English as something like "I declare something, which is a pointer to an integer." The "pointer" goes along with the "integer" much more so than it does with the "something." In contrast, the other uses of the ampersand and asterisk, as address-of and dereferencing operators, act on a variable. Here are the other two styles (maybe there are more but I really hope not): int *ugly_but_common; int * uglier_but_fortunately_less_common; Why? Really, why? I can never think of a case where the second is appropriate, and the first only suitable perhaps with something like: int *hag, *beast; But come now... multiple variable declarations on one line is kind of ugly form in itself already.

  • Flash AS3: Loading bar not finished when movie starts playing

    - by flashey
    Hi, I'm using the same code I always use for preloading another swf but it's not working this time. The problem this time is that when the loading bar gets to 16% every time you can hear the movie I'm loading playing in the background. I can just add a stop to the first frame of the movie I'm loading ("trial_1.swf") but how do I tell it to go to the second frame once it has loaded? Any help is much appreciated! Here's my code: var myrequest:URLRequest=new URLRequest ("trial_1.swf"); var myloader:Loader = new Loader(); myloader.load(myrequest); myloader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, progresshandler); function progresshandler(myevent:ProgressEvent):void { var myprogress:Number=myevent.target.bytesLoaded/myevent.target.bytesTotal; bar_mc.scaleX=myprogress*1.5; myTextField_txt.text = Math.round(myprogress*100)+"%" } myloader.contentLoaderInfo.addEventListener(Event.COMPLETE, finished); function finished(myevent:Event):void { addChild(myloader); removeChild(myTextField_txt) removeChild(bar_mc); removeChild(logo_mc); }

  • ios 4.1 doesn't call Phonegap API

    - by Johannes Klauß
    I'm working on a cross platform app for Android 2.2 and iOS 4.1 (dev devices). On Android everything works fine (accelerometer and geolocation) even if it's a little laggy. On iOS it's way more smooth, but he doesn't call the Phonegap functions. That's my JS code: var watchID = null; var shaking = { left: false, right: true }; function startWatch() { // Update acceleration every 100 ms var options = { frequency : 100 }; watchID = navigator.accelerometer.watchAcceleration(function(acceleration) { if(acceleration.x < -8) { shaking.left = true; } else if(acceleration.x > 8) { shaking.right = true; } if(shaking.left && shaking.right) { navigator.notification.vibrate(500); shaking.left = false; shaking.right = false; stopWatch(); } }, null, options); } I just call it with <a href="" onclick="startWatch();">start Accel</a> But iOS doesn't react at all. Is there any special call you need to do in iOS?

  • order of onclick events

    - by NicoF
    I want to add a jquery click event to href's that already have an onclick event. In the example below the hard coded onclick event will get triggered first. How can I reverse that? <a class="whatever clickyGoal1" href="#" onclick="alert('trial game');">play trial</a> <br /> <a class="whatever clickyGoal2" href="#" onclick="alert('real game');">real trial</a> <p class="goal1"> </p> <p class="goal2"> </p> <script type="text/javascript"> $("a.clickyGoal1").click(function() { $("p.goal1").append("trial button click goal is fired");//example }); $("a.clickyGoal2").click(function() { $("p.goal2").append("real button click goal is fired"); //example }); </script>

  • core dump during std::_List_node_base::unhook()

    - by Ron
    I have a program where std::list is used. The program uses threads which act on the std::list as producers and consumers. When a message is dealt with by the consumer, it is removed from the list using pop_front(). But, during pop_front, there is a core dump. The gdb trace is as below. could you help getting me some insights into this issue?

  • Upload using python script takes very long on one laptop as compared to another

    - by Engr Am
    I have a python 2.7 code which uses STORBINARY function for uploading files to an ftp server and RETRBINARY for downloading from this server. However, the issue is the upload is taking a very long time on three laptops from different brands as compared to a Dell laptop. The strange part is when I manually upload any file, it takes the same time on all the systems. The manual upload rate and upload rate with the python script is the same on the Dell Laptop. However, on every other brand of laptop (I have tried with IBM, Toshiba, Fujitsu-Siemens) the python script has a very low upload rate than the manual attempt. Also, on all these other laptops, the upload rate using the python script is the same (1Mbit/s) while the manual upload rate is approx. 8 Mbit/s. I have tried to vary the filesize for the upload to no avail. TCP Optimizer improved the download rate on all the systems but had no effect on the upload rate. Download rate using this script on all the systems is fine and same as the manual download rate. I have checked the server and it has more than 90% free space. The network connection is the same for all the laptops, and I try uploading only with one laptop at a time. All the laptops have almost the same system configurations, same operating system and approximately the same free drive space. If anything the Dell laptop is a little less in terms of processing power and RAM than 2 of the others, but I suppose this has no effect as I have checked many times to see how much was the CPU usage and network usage during these uploads and downloads, and I am sure that no other virus or program has been eating up my bandwidth. Here is the code ('ftp' and 'file_path' are inputs to the function): path,filename=os.path.split(file_path) filesize=os.path.getsize(file_path) deffilesize=(filesize/1024)/1024 f = open(file_path, "rb") upstart = time.clock() print ftp.storbinary("STOR "+filename, f) upende = time.clock()-upstart outname="Upload " f.close() return upende, deffilesize, outname

  • Sphinx - Python modules, classes and functions documentation

    - by user343934
    Hi everyone, I am trying to document my small project through sphinx which im recently trying to get familiar with. I read some tutorials and sphinx documentation but couldn't make it. Setup and configurations are ok! just have problems in using sphinx in a technical way. My table of content should look like this --- Overview .....Contents ----Configuration ....Contents ---- System Requirements .....Contents ---- How to use .....Contents ---- Modules ..... Index ......Display ----Help ......Content Moreover my focus is on Modules with docstrings. Details of Modules are Directory:- c:/wamp/www/project/ ----- Index.py >> Class HtmlTemplate: .... def header(): .... def body(): .... def form(): .... def header(): .... __init_main: ##inline function ----- display.py >> Class MainDisplay: .... def execute(): .... def display(): .... def tree(): .... __init_main: ##inline function My Documentation Directory:- c:/users/abc/Desktop/Documentation/doc/ --- _build --- _static --- _templates --- conf.py --- index.rst I have added Modules directory to the system environment and edited index.rst with following codes just to test Table of content. But i couldn't extract docstring directly Index.rst T-Alignment Documentation The documentation covers general overview of the application covering functionalities and requirements in details. To know how to use application its better to go through the documentation. .. _overview: Overview .. _System Requirement: System Requirement Seq-alignment tools can be used in varied systems base on whether all intermediary applications are available or not like in Windows, Mac, Linux and UNIX. But, it has been tested on the Windows working under a beta version. System Applications Server .. _Configuration:: Configuration Basic steps in configuration involves in following categories Environment variables Apache setting .. _Modules:: Modules How can i continue from here... Moreover, i am just a beginner to sphinx documentation tool I need your suggestions to brings my modules docstring to my documentation page Thanks

  • I trying to backreference using the sed command

    - by Paul
    I am relative new to shell scripting and sed. I need to substitute a pattern, globably, but I also need to remember (or save) part of the pattern and use it later in the same substitute command. The saved pattern will be varible, so I need to use a wild card. For example, input message=trt:GetAudioSourcesRequest/> and I want to end up with something like input message=trt:GetAudioSourcesRequest PAUL/GetAudioSourcesRequest/> but the function string "GetAudioSourcesRequest" will change (in length also) throughtout the file, so I need a wild card, e.g. sed -i "s/input message=trt:<wild card in here>/>/input message=trt:<print wild card> PAUL/<print wild card>/> I have managed to get the following command to nearly do what I want but it is too rigid. It only stores a 4 syllable pattern so if I have a function name such as GetProfileRequest, this doesn't work echo "input message=\"trt:GetAudioSourcesRequest\"/>" | sed 's/input message=\"trt:\([A-Z][a-z]*\)\([A-Z][a-z]*\)\([A-Z][a-z]*\)\([A-Z][a-z]*\).*/input message=\"trt:\1\2\3\4\ PAUL\/\1\2\3\4"\/\>/g' This outputs input message="trt:GetAudioSourcesRequest PAUL/GetAudioSourcesRequest"/> Which is ok but when I use GetProfileRequest this doesn't. I have come accross \W and [^[:alnum:]] or [[:alnum:]] but I don't how to use them Thanks in advance.

  • Programmatically change an EditorGrid's cell value

    - by Snowright
    Hi, I have an Editor Grid where if a specific cell is in focus (is being edited), a window containing a tree panel pops up allowing the user to choose a node from the treepanel as the new value of the cell. This way, the user isn't actually editing the cell in question, but is using the window to choose the new value. However, I am having difficulties setting the value of the cell in question programmatically. Below is the code I use to set the grid up, including the column model that chooses what editor to use for a cell depending on the value type: var editorCM = new Ext.grid.ColumnModel({ //config ,editors : { //rest of editors 'id' : new Ext.grid.GridEditor(new Ext.form.TextField({readOnly : true})) } ,getCellEditor : function(col, row) { //choose editor depending on the type value of a cell } }) var editorGrid = new Ext.grid.EditorGridPanel({ //rest of config ,cm : editorCM }) Below is my code to change the cell's value once the user chooses from the treepanel. function submitNode(newValue) { var temp = editorGrid.GetSelectionModel().getSelectedCell(); //returns array containing column and row position of selected cell, which value we want to change. //temp[1] = column index, temp[0] = row index //Gets the cell editor at specific position and sets new value for that cell editorGrid.getColumnModel().getCellEditor(temp[1], temp[0]).setValue(newValue); } I've also tried a few other ways (all including setValue(newValue)), but have come up empty handed. I've looked through the API and the ExtJS forums for any clue but have also come up empty handed.

  • Zend_Form using subforms getValues() problem

    - by wiseguydigital
    Hi all, I am building a form in Zend Framework 1.9 using subforms as well as Zend_JQuery being enabled on those forms. The form itself is fine and all the error checking etc is working as normal. But the issue I am having is that when I'm trying to retrieve the values in my controller, I'm receiving just the form entry for the last subform e.g. My master form class (abbreviated for speed): Master_Form extends Zend_Form { public function init() { ZendX_JQuery::enableForm($this); $this->setAction('actioninhere') ... ->setAttrib('id', 'mainForm') $sub_one = new Form_One(); $sub_one->setDecorators(... in here I add the jQuery as per the docs); $this->addSubForm($sub_one, 'form-one'); $sub_two = new Form_Two(); $sub_two->setDecorators(... in here I add the jQuery as per the docs); $this->addSubForm($sub_two, 'form-two'); } } So that all works as it should in the display and when I submit without filling in the required values, the correct errors are returned. However, in my controller I have this: class My_Controller extends Zend_Controller_Action { public function createAction() { $request = $this->getRequest(); $form = new Master_Form(); if ($request->isPost()) { if ($form->isValid($request->getPost()) { // This is where I am having the problems print_r($form->getValues()); } } } } When I submit this and it gets past isValid(), the $form-getValues() is only returning the elements from the second subform, not the entire form.

  • MSBuild file for deployment process

    - by Lee Englestone
    I could do with some pointers, code examples or references that may help me do the following in an msbuild file to help speed up the deployment process.. This scenario involves getting a developers 'local' version onto a 'development' server.. Increment a developers local Web Applications Assembly version number Publish a developers local Web Application files somewhere .rar the publsihed files or folder into the format v[IncrementedAssemblyNumber].rar Copy the .rar to somewhere Backup (.rar) the existing live website folder (located elsewhere) in the format Pre_v[IncrementedAssemblyNumber].rar Move the backed up .rar to a /Backup folder. Overwrite the development web files with the published local web files Should be simple for all those MSBUILD Gurus out there. Like I said, answers or 'Good and applicable' links would be much appreciated. Also i'm thinking of getting one of the MSbuild books. From what I can tell there are 2, possibly 3 contenders. I am not using TFS. Can anyone recommend a book for beginning MSBUILD? Ideally from people that have read more than one book on the subject. Cheers, -- Lee

  • mysqldb interfaceError

    - by Johanna
    I have a very weird probleme with mysqldb (mysql module for python). I have a file with queries for inserting records in tables. If I call the functions from the file, it works just fine. But when I try to call one of the functions from another file it throws me a _mysql_exception.InterfaceError: (0, '') I really don't get what I'm doing wrong here.. I call the function from buildDB.py : import create create.newFormat("HD", 0,0,0) The function newFormat(..) is in create.py (imported) : from Database import Database db = Database() def newFormat(name, width=0, height=0, fps=0): format_query = "INSERT INTO Format (form_name, form_width, form_height, form_fps) VALUES ('"+name+"',"+str(width)+","+str(height)+","+str(fps)+");" db.execute(format_query) And the class Databse is the following : import MySQLdb from MySQLdb.constants import FIELD_TYPE class Database(): def __init__(self): server = "localhost" login = "seq" password = "seqmanager" database = "Sequence" my_conv = { FIELD_TYPE.LONG: int } self.conn = MySQLdb.connection(host=server, user=login, passwd=password, db=database, conv=my_conv) # self.cursor = self.conn.cursor() def close(self): self.conn.close() def execute(self, query): self.conn.query(query) (I put only relevant code) Traceback : Z:\sequenceManager\mysql>python buildDB.py D:\ProgramFiles\Python26\lib\site-packages\MySQLdb\__init__.py:34: DeprecationWa rning: the sets module is deprecated from sets import ImmutableSet INSERT INTO Format (form_name, form_width, form_height, form_fps) VALUES ('HD',0 ,0,0); Traceback (most recent call last): File "buildDB.py", line 182, in <module> create.newFormat("HD") File "Z:\sequenceManager\mysql\create.py", line 52, in newFormat db.execute(format_query) File "Z:\sequenceManager\mysql\Database.py", line 19, in execute self.conn.query(query) _mysql_exceptions.InterfaceError: (0, '') The warning has never been a problem before so I don't think it's related.

  • C programming: Dereferencing pointer to incomplete type error

    - by confusedKid
    Hi, I am pretty rusty at C, and I'm getting a dereferencing error. Hopefully someone can help me with this? ^_^ I have a struct defined as: struct { char name[32]; int size; int start; int popularity; } stasher_file; and an array of pointers to those structs: struct stasher_file *files[TOTAL_STORAGE_SIZE]; In my code, I'm making a pointer to the struct and setting its members, and adding it to the array: ... struct stasher_file *newFile; strncpy(newFile-name, name, 32); newFile-size = size; newFile-start = first_free; newFile-popularity = 0; files[num_files] = newFile; ... I'm getting a "error: dereferencing pointer to incomplete type" whenever I try to access the members inside newFile. What am I doing wrong? Thanks very much for any help :)

  • lambda traits inconsistency across C++0x compilers

    - by Sumant
    I observed some inconsistency between two compilers (g++ 4.5, VS2010 RC) in the way they match lambdas with partial specializations of class templates. I was trying to implement something like boost::function_types for lambdas to extract type traits. Check this for more details. In g++ 4.5, the type of the operator() of a lambda appears to be like that of a free standing function (R (*)(...)) whereas in VS2010 RC, it appears to be like that of a member function (R (C::*)(...)). So the question is are compiler writers free to interpret any way they want? If not, which compiler is correct? See the details below. template <typename T> struct function_traits : function_traits<decltype(&T::operator())> { // This generic template is instantiated on both the compilers as expected. }; template <typename R, typename C> struct function_traits<R (C::*)() const> { // inherits from this one on VS2010 RC typedef R result_type; }; template <typename R> struct function_traits<R (*)()> { // // inherits from this one g++ 4.5 typedef R result_type; }; int main(void) { auto lambda = []{}; function_traits<decltype(lambda)>::result_type *r; // void * } This program compiles on both g++ 4.5 and VS2010 but the function_traits that are instantiated are different as noted in the code.

  • Calling handwritten CUDA kernel with thrust

    - by macs
    Hi, since i needed to sort large arrays of numbers with CUDA, i came along with using thrust. So far, so good...but what when i want to call a "handwritten" kernel, having a thrust::host_vector containing the data? My approach was (backcopy is missing): int CUDA_CountAndAdd_Kernel(thrust::host_vector<float> *samples, thrust::host_vector<int> *counts, int n) { thrust::device_ptr<float> dSamples = thrust::device_malloc<float>(n); thrust::copy(samples->begin(), samples->end(), dSamples); thrust::device_ptr<int> dCounts = thrust::device_malloc<int>(n); thrust::copy(counts->begin(), counts->end(), dCounts); float *dSamples_raw = thrust::raw_pointer_cast(dSamples); int *dCounts_raw = thrust::raw_pointer_cast(dCounts); CUDA_CountAndAdd_Kernel<<<1, n>>>(dSamples_raw, dCounts_raw); thrust::device_free(dCounts); thrust::device_free(dSamples); } The kernel looks like: __global__ void CUDA_CountAndAdd_Kernel_Device(float *samples, int *counts) But compilation fails with: error: argument of type "float **" is incompatible with parameter of type "thrust::host_vector *" Huh?! I thought i was giving float and int raw-pointers? Or am i missing something?

  • ActionScript 3.0 Getting Size/Coordinates From Loader Content

    i'm attempting to position a textfield to the bottom left of an image that is added to the display list from the Loader() class. i don't know how to access the width/height information of the image. var dragSprite:Sprite = new Sprite(); this.addChild(dragSprite); var imageLoader:Loader = new Loader(); imageLoader.load(new URLRequest("picture.jpg")); imageLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, displayPic, false, 0, true); function displayPic(evt:Event):void { dragSprite.addChild(evt.target.content); evt.target.removeEventListener(Event.COMPLETE, displayPic); } var tf:TextField = new TextField(); tf.text = "Picture Title"; tf.width = 200; tf.height = 14; tf.x //same x coordinate of dragSprite tf.y //same y coordinate of dragSprite, plus picture height, plus gap between picture and text addChild(tf); within the displayPic function, i could assign the evt.target.content.height and evt.target.content.width to variables that i could use to position the text field, but i assume there is a better way?

  • Accessing functions in a swf-file through javascript [chatroulette.com]

    - by RadiantHeart
    Lately I have been interested in the code behind chatroulette.com. As you probably know it is a peer-to-peer webcam-chat-service written in actionscript, as I understand. What i have been wondering about is weather its possible to extract the ip-address of whomever you are currently communicating with. I have seen services that do that, but they require that you install a program that runs alongside on your computer sniffing UDP-packages. I was wondering if there was a simpler method. What I do know is that the javascript on the page communicates with the application via "ExternalInterface". On this area I am pretty much a novice but according to my limited understanding you cant get information from the flash-application unless you have configured a listener for a call from javascript and then attach a callback to that event. Is this correct or can you access public functions and variables directly through javascript? There is for example a public function like this: public function get outgoingAddress():String{ return (this.__info.outgoingAddress); } Can it be accessed directly through javascript? If it cant be done so easily, is it possible to decompile the .swf-file, change it (add some functions) and recompile it and run it instead? I am hoping someone can satisfy my curiosity here. Here are two links to a decompiled version of the swf-file. The first with line numbering and one without. With line numbering ˜ 3.5 Mbyte Without line numbering ˜ 2.1 Mbyte

  • jQuery tooltip: Trouble with remove()

    - by Rosarch
    I'm using a jQuery tooltip plugin. I have HTML like this: <li class="term ui-droppable"> <strong>Fall 2011</strong> <li class="course ui-draggable">Biological Statistics I<a class="remove-course-button" href="">[X]</a></li> <div class="term-meta-data"> <p class="total-credits too-few-credits">Total credits: 3</p> <p class="median-GPA low-GPA">Median Historical GPA: 2.00</p> </div> </li> I want to remove the .course element. So, I attach a click handler to the <a>: function _addDeleteButton(course, term) { var delete_button = $('<a href="" class="remove-course-button" title="Remove this course">[X]</a>'); course.append(delete_button); $(delete_button).click(function() { course.remove(); return false; }).tooltip(); } This all works fine, in terms of attaching the click handler. However, when course.remove() is called, Firebug reports an error in tooltip.js: Line 282 tsettings is null if ((!IE || !$.fn.bgiframe) && tsettings.fade) { What am I doing wrong? If the link has a tooltip attached, do I need to remove it specially? UPDATE: Removing .tooltip() solve the problem. I'd like to keep it in, but that makes me suspect that my use of .tooltip() is incorrect here.

  • [ZF & jQuery] How can I access an URL using AJAX, receive no response, but just manipulate HTML?

    - by rasouza
    I don't know if it's better used with AJAX (tell me, otherwise) but here is my problem: Assuming i'm using Zend Framework, I have a table with several registries from a database with a delete button on each row. That's like this [...] <tbody> <?php foreach ($row as $reg) { ?> <tr <?php if ($reg['value'] < 0) { echo "class='error'"; } ?>> <td><?php echo $reg['creditor'] ?></td> <td><?php echo $reg['debtor'] ?></td> <td><?php echo $reg['reason'] ?></td> <td>R$ <?php echo number_format(abs($reg['value']), 2, ',', ' ')?></td> <td><a href="#" id="<?php echo $reg['id']; ?>" class="delete"><img src="http://192.168.0.102/libraries/css/blueprint/plugins/buttons/icons/cross.png" alt=""/></a></td> </tr> <?php } ?> </tbody> [...] I would like to .fadeOut() and delete (through the link history/delete/id/ROW_ID ) a table row when clicked in the respective delete button. My deleteAction() has no render. It really shouldn't have one, it just deletes a row in the database. Still, how can I make it happen? I tried: // TR Fading when deleted $('.delete') .click(function() { $.ajax({ type: 'GET', url: 'history/delete/id/'+$(this).attr('id'), success: function() { $(this).parent().parent().fadeOut(); } }); return false; }); without success

  • How to pass dynamic parameters to .pde file

    - by Kalpana
    class Shape contains two methods drawCircle() and drawTriangle(). Each function takes different set of arguments. At present, I invoke this by calling the pde file directly. How to pass these arguments from a HTML file directly if I have to control the arguments being passed to the draw function? 1) Example.html has (current version) <script src="processing-1.0.0.min.js"></script> <canvas data-processing-sources="example.pde"></canvas> 2) Example.pde has class Shape { void drawCircle(intx, int y, int radius) { ellipse(x, y, radius, radius); } void drawTriangle(int x1, int y1, int x2, int y2, int x3, int y3) { rect(x1, y1, x2, y2, x3, y3); } } Shape shape = new Shape(); shape.drawCircle(10, 40, 70); I am looking to do something like this in my HTML file, so that I can move all the functions into a separate file and call them with different arguments to draw different shapes (much similar to how you would do it in Java) A.html <script> Shape shape = new Shape(); shape.drawCircle(10, 10, 3); </script> B.html <script> Shape shape = new Shape(); shape.drawTriangle(30, 75, 58, 20, 86, 75); </script> 2) Iam using Example2.pde has void setup() { size(200,200); background(125); fill(255); } void rectangle(int x1, int y1, int x2, int y2) { rect(x1, y1, x2, y2); } My Example2.html has var processingInstance; processingInstance.rectangle(30, 20, 55, 55); but this is not working. How to pass these parameters dynamically from html.
