• How to explain DRM cannot work?

  - by jerryjvl

  I am looking for the shortest comprehensive way to explain to people that are trying to use DRM as a technology to prevent users from using their data in some fashion deemed undesirable, why their solution cannot work by definition. Ideally I'd like something that: Covers why technically it is impossible to have people access local data, but only in such-and-such a way Imparts an understanding of why this is, to avoid follow-on "But what if" rebuttals Is intuitive enough and short enough that even a politician (j/k) could grasp it When faced with this situation I try to be clear and concise, but I usually end up failing at least on one of these points. I'd really like to have a 'stock' answer that I can use in the future.

• IE6 forces Two clicks to trigger javascript style=display:inline; event

  - by JiminyCricket

  I have a web form that has 2 radio buttons, depending on which one is clicked it displays a hidden element This works fine in all browsers except for IE6, which, after I click on the radio button, I have to click again (anywhere on the window) and then the element is displayed...has anyone had behavior like this before? I tried to not use jQuery and do straight getElementById() but I get the same behavior... JSCRiPT function showHidden(divid) { $('#'+divid).css( {'display':'inline'} ); } HTML <input type=radio name=borp value=1 onChange='showHidden("brandchecks")' > Brand <input type=radio name=borp value=2 onChange='showHidden("productchecks")' > Product <div id='brandchecks' style='display:none;'> Blah </div> <div id='productchecks' style='display:none;'> Blah </div>

• Get values from HTML in a multidimensional array and calculate values using PHP

  - by Frank Nwoko

  I have searched but could not get solution on this issue. I am working on an application which will generate unknown number of items and have users select the quantity from a drop down against each item. Eg. Item(s) | price | Select qty Rice 23 3 Beans 22 4 Eggs 52 5 ... ... ... unknown Please, how can I capture the above in an array and also calculate the total value for all selected items and corresponding fees? I have the following HTML code: <form id='form1' name='form1' method='post' action='item_calc.php'> <?php ..... while($t_row = mysql_fetch_assoc($get_items)) { echo "<p><label>$t_row['$item_name'] <input type='text' READONLY name='item_price[]' value='$t_row['$item_price']' /></label> <input type='text' READONLY name='item_fees[]' value='$t_row['$item_fee']' /> <select name="item_qty"> <option value="1"> <option value="2"> <option value="3"> <option value="4"> <option value="5"> </select> </p><p>"; } echo "<label><input type='submit' name='submit' value='Submit' /></label></p> </form>"; Please, how can I get item_price[] + item_fees[] * item_qty for all selected items? This is what I have tried: for ($i = 0; $i < count($_POST['item_price']); $i++) { // Do something here with $_POST['checkbx'][$i] foreach ($_POST['item_fees'] as $tkey => $tvalue) { //echo "Key: $tkey; Value: $tvalue<br>"; } foreach ($_POST['item_price'] as $pkey => $pvalue) { //echo "Key: $pkey; Value: $pvalue<br>"; } $total = $tvalue + $pvalue; } echo $total;

• Go - Concurrent method

  - by nevalu

  How to get a concurrent method? In my case, the library would be called from a program to get a value to each argument str --in method Get()--. When it's used Get() then it assigns a variable from type bytes.Buffer which it will have the value to return. The returned values --when it been concurrently called-- will be stored into a database or a file and it doesn't matter that its output been of FIFO way (from method). type test struct { foo uint8 bar uint8 } func NewTest(arg1 string) (*test, os.Error) {...} func (self *test) Get(str string) ([]byte, os.Error) { var format bytes.Buffer ... } I think that all code inner of method Get() should be put inner of go func() {...}(), and then to use a channel. Would there be a problem if it's called another method from Get()? Or would it also has to be concurrent?

• Best way to set a default button (or trigger its event in javascript) for an input field, not part of a form

  - by Sheldon Pinkman

  I've got a stand-alone input field, not part of any form. I also got a button, that has some onclick event. When I type something in the input field, and press the Enter key, I want it do effectively press the button, or trigger its onclick event. So that the button is "the input field's default button" so to speak. <input id='myText' type='text' /> <button id='myButton' onclick='DoSomething()'>Do it!</button> I guess I can mess around with the input field's onkeypress or onkeydown events and check for the Enter key, etc. But is there a more 'clean' way, I mean something that associated the button with that input field, so that the button is the 'default action' or something for that field? Note that I'm not inside a form, I am not sending, posting, or submitting something. The DoSomething() function just changes some of the HTML content locally, depending on the text input.

• IE - hidden radio button not checked when the corresponding label is clicked

  - by ScottE

  I just noticed a strange behaviour in IE7. I have radio buttons with associated labels as follows: <input type="radio" name="filter" id="filter_1" value="Activities" checked="checked" /> <label for="filter_1">Activities</label> <input type="radio" name="filter" id="filter_2" value="Services" /> <label for="filter_2">Services</label> The radio button is hidden via css with display:none or visibility: hidden (don't ask) The problem is - when I click the label in IE7 (haven't looked at other IE versions yet) the associated radio button is not actually checked. I confirmed this with jquery - the label click event is fired, but the radio button click event is not. A form post also confirms that the checked radio button does not change. This works correctly in firefox, and also works correctly if I remove the CSS that hides the radio buttons. Is this an IE bug or am I missing something?

• Need help with displaying the message correctly in the pole display always starting at the beginning

  - by SA

  Hi, I am using an HP RS232 pole display with the following setting: Char type: USA/Europe (default) Command mode: EPSON (default) Baud rate: 9600, n , 8, 1 (default?) Passthru None (Default) Here's the code using System.IO.Ports; private SerialPort port; port = new SerialPort("COM2", 9600, Parity.None, 8, StopBits.One); port.Handshake = Handshake.None; Port.WriteLine("Welocome to something something"); It has 2 lines consisting of 20 characters each with a total of 40 characters. I have no control how and where the characters get displayed. I would like it to always begin on line 1 position 1 but as I said earlier how would I be able to do that. The same program if I run again and again it moves a character to the left. I have set it to accept ASCII char set and so I am able to type as is visble in the Writeline message

• jquery replaceWith implications

  - by Vlad Ioffe

  I am using replaceWith for input type=file to handle changes of the file the user wants to upload. I have this code: $('#add_cv_input').change(function() { // here is some code else { alert('put one of this: pdf doc docx'); $("#add_cv_input").replaceWith('<input id="add_cv_input" type="file"/>'); } }); now the problem is that this jquery changed event does not being called after the first time that the user had uploaded the wrong extension. I don't have a clue why this is happening. Everything works fine if at the first time the user uploads a valid extension and then he changes it to other valid extension.

• T4MVC and Ajax method with parameter

• Can't return nil, but zero value of slice

  - by Sergi

  I am having the case in which a function with the following code: func halfMatch(text1, text2 string) []string { ... if (condition) { return nil // That's the final code path) } ... } is returning []string(nil) instead of nil. At first, I thought that perhaps returning nil in a function with a particular return type would just return an instance of a zero-value for that type. But then I tried a simple test and that is not the case. Does anybody know why would nil return an empty string slice?

• Highlighting a radio button with CSS

  - by dsoftware

  I have been trying to highlight a radio button with CSS but have been unsuccessful to get styling to work in FireFox. I see some methods of using images to render highlighting. Is there a preferred way to handle radio button highlighting across multiple browsers? Example <input type="text" style="border-color:#FF0000"> <input type="radio" style="border-color:#FF0000"> The text box will have a border that is red but the radio button will not take the border color?

• Selecting the usercontrol to the relating datatemplate in mvvm

  - by msfanboy

  Hello, I have lets say a WeeklyViewUserControl.xaml and a DailyViewUserControl.xaml. Normally I used stuff like this to switch content: <DataTemplate DataType="{x:Type ViewModel:LessonPlannerViewModel}"> <View:LessonPlannerDailyUC/> </DataTemplate> This worked so far. But now I have still the WeeklyViewUC which uses 90 % of the LessonPlannerViewModel code so I want to make this additionally: <DataTemplate DataType="{x:Type ViewModel:LessonPlannerViewModel}"> <View:LessonPlannerWeeklyUC/> </DataTemplate> but this can not work, because from where does the ContentControl know that VM (LessonPlannerViewModel) should display a DailyViewUC or a WeeklyViewUC ? <ContentControl Content="{Binding VM}" />

• Why are my JavaScript variables not persisting across functions?

  - by Eric Belair

  I have the following JavaScript in my HTML page referencing an HTML form on the page: <script type="text/javascript"> <!-- var myForm = document.myForm; function validateForm() { if (myForm.myInput == "") alert("Please input some text."); return false; } myForm.submit(); } function showFormInput() { myForm.reset(); document.getElementById('myInput').style.display = 'inline'; } //--> </script> ... <form name="myForm" id="myForm" action="..." method="post"> <input id="myInput" name="myInput" type="text" value="" style="display:none;" /> </form> Both functions are throwing an exception when trying to access the variable myForm, saying that "myForm is null or not an object". Why is this occurring?

• How do you optimize database performance when providing results for autocomplete/iterative search?

  - by Howiecamp

  Note: In this question I'm using the term "autocomplete" (or "iterative search") to refer to returning search-as-you-type results, e.g. like Google Search gives you. Also my question is not specific to web applications vs. fat client apps. How are SQL SELECT queries normally constructed to provide decent performance for this type of query, especially over arbitrarily large data sets? In the case where the search will only query based on the first n characters (easiest case) am I still issuing a new SELECT result FROM sometable WHERE entry LIKE... on each keypress. Even with various forms of caching this seems like it might result in poor performance. In cases where you want your search string to return results with prefix matches, substring matches, etc. it's an even more difficult problem. Looking at a case of searching a list of contacts, you might return results that match FirstName + LastName, LastName + FirstName, or any other substring.

• How to trigger an event in input text after I stop typing/writting?

  - by user1386320

  I want to trigger event just right after I stop typing (not while typing) characters in my input textbox. I've tried with: $('input#username').keypress(function() { var _this = $(this); // copy of this object for further usage setTimeout(function() { $.post('/ajax/fetch', { type: 'username', value: _this.val() }, function(data) { if(!data.success) { // continue working } else { // throw an error } }, 'json'); }, 3000); }); But this example produces a timeout for every typed character and I get about 20 AJAX requests if I type-in 20 characters. On this fiddle I demonstrate the same problem with a simple alert instead of an AJAX. Is there a solution for this or I'm just using a bad approach for this?

• Django ORM dealing with MySQL BIT(1) field

  - by Carles Barrobés

  In a Django application, I'm trying to access an existing MySQL database created with Hibernate (a Java ORM). I reverse engineered the model using: $ manage.py inspectdb > models.py This created a nice models file from the Database and many things were quite fine. But I can't find how to properly access boolean fields, which were mapped by Hibernate as columns of type BIT(1). The inspectdb script by default creates these fields in the model as TextField and adds a comment saying that it couldn't reliably obtain the field type. I changed these to BooleanField but it doesn't work (the model objects always fetch a value of true for these fields). Using IntegerField won't work as well (e.g. in the admin these fields show strange non-ascii characters). Any hints of doing this without changing the database? (I need the existing Hibernate mappings and Java application to still work with the database).

• How can I write this Table Valued Function as a Stored Procedure?

  - by Alex

  I have the following TVF for fulltext search: FUNCTION [dbo].[Fishes_FullTextSearch] (@searchtext nvarchar(4000), @limitcount int) RETURNS TABLE AS RETURN SELECT * FROM Fishes INNER JOIN CONTAINSTABLE(Fishes, *, @searchtext, @limitcount) AS KEY_TBL ON Fishes.Id = KEY_TBL.[KEY] When I'm using this TVF, it doesn't return a collection of objects of type Fish (which I want!) - instead LINQ creates a new result type which includes all "Fish" fields and the fields Key and Rank. In another question, it was suggested that I rewrite this TVF into a stored procedure for it to return Fish objects only. Can someone help me do this please? Also, it needs to be ordered by Rank. Thank you!

• How to increase the volume gain when viewing online flash video?

  - by Nick000

  When watching online Flash videos on Youtube, Dailymotion, etc... sometimes the videos are recorded at low volume. The thing is that, I have a HP Notebook with good enough audio volume, but when I watch these "low volume" videos the sound level is really low, even when I have the volume at 100%. So I am looking for a way to increase the volume gain (like VLC player where you can increase it to 200%), BUT while watching it live on Youtube... that is, I don't want to download the video on my PC. Is there a software that can do that? Maybe an advanced flash video player that integrates to browser? or some other software to increase the volume gain overall on my laptop? My Specs: HP Pavilion Notebook, Audio: IDT High Definition Audio CODEC (integrated), Vista 64-bit, 4 GB RAM, etc.....
