  • How does Git know which Index blob to add to a tree?

    - by drozzy
    In Pro Git Ch9 the author says: Git normally creates a tree by taking the state of your staging area or index and writing a tree object from it. My question is how does git know which of two consequitive index entries to create the Tree object from? For example: $ echo 'First change' > one.txt $ git add one.txt $ find .git/objects -type f .git/objects/1f/755a7fffe4 //first index entry $ echo 'Second change' > one.txt $ git add one.txt $ find .git/objects -type f .git/objects/2d/234asdf2 //second index entry $ git commit -a -m "Initial commit" $ git cat-file master^{tree} 100644 blob 2d234asdf2 one.txt //How did it know not to take 1f755?? Does it just look at the blob timestamps? Also - what happens to the first blob created - no one is referencing it. Does it just get destroyed or forgotten?

  • Variable pre-fixes, Visual Studio 2010 onwards?

    - by thedixon
    I'm a bit bewildered on this subject, as I relate variable prefixes to being a thing of the past now, but with Visual Studio 2010 onwards (I'm currently using 2012), do people still do this and why? I only ask because, these days, you can hover over any variable and it'll tell you the variable type and scope. There's literally no requirement for pre-fixing being there for readability. By this I mean: string strHello int intHello etc. And I'm being language/tool biased here - as Visual Studio takes a lot of the legwork out for you in terms of seeing exactly what type the variable is, including after conversions in the code. This is not a "general programming" question.

  • jQuery doesn't work in <head>?!

    - by Hanz
    This code is supposed to make a slideshow out of stacked list-elements (I commented out the CSS so I can see what's going on) by fading out the topmost elements until only the first one is visible, then fade in the topmost element and the rest and start anew. If I put the script below my content inside the <body> and throw out the $(function() { it works perfectly fine, but in the <head> nothing happens. I wrote this yesterday and today I still can't see the mistake, so I'm posting it here. <!DOCTYPE html> <html> <head> <title></title> <style type="text/css"> ul { position: relative; } ul li { /*position: absolute; left: 0; top: 0;*/ } </style> <script src="jquery-1.5.1.min.js" type="text/javascript"></script> <script type="text/javascript"> $(function() { var i = 0; var count = $('ul li').size(); function fade() { if (i < count-1) { $('ul li:nth-child('+(count-i)+')').fadeOut(300); i++; } else { $('ul li:nth-child('+count+')').fadeIn(300, function(){$('ul li').show();}); i = 0; } } $('button').click(function() { setInterval('fade()', 1000); }); }); </script> </head> <body> <button>Slideshow GO!</button> <ul id="slider"> <li><img src="1.jpg" /></li> <li><img src="2.jpg" /></li> <li><img src="3.jpg" /></li> <li><img src="4.jpg" /></li> </ul> </body> </html> Thanks

  • Sql-server Database query help

    - by menacheb
    Hi, I have a problem that I didn't manage to solve for a very long time, and I quite desperate. I have a Database (SQL Server) with table named 'ProcessData' and columns named 'Process_Name' (Data Type: nvarchar(50)), 'Start_At' (DataType: DateTime) and 'End_At' (Data Type: DateTime). I need to know for each 'Time-Interval' (let's say 1 minute) how many processes (Process_Name = PN) was open (after or equal to the 'Start_at' column and before or equal to the 'End_At' column) during this time (It can be a few rows with the same data). Does anyone know how to make this query without a 'for' loop? (It ITSELF will promote the time), (The answer will be a table with two columns (1. The time the check took place. 2. the number of open processes at this time.) and a row for each 'Time-Interval' (1 minute in this example ) Many thanks,

  • Calling C++/CLI Method with System::DateTime parameter requires 'ValueType' as a parameter?

    - by David Ipsen
    I'm attempting to call a method written in C++/CLI from C#. The C++/CLI code is used to update a TIMESTAMP column in an Oracle database, given a record ID and the System::DateTime object which is the .NET compatible data type for Oracle's TIMESTAMP type. The method I am calling has the following prototype: bool ChangeJobUpdateDate (int jobIdIn, System::DateTime^ updateDateIn) I've added a reference to this DLL project in a test project that I made; I'm writing the tests in C#. However, when I try to call this method from the C# unit test project, the function appears to have the following method declaration (via intellisense): bool ChangeJobUpdateDate (int jobIdIn, ValueType updateDateIn) I'm admittedly not that familiar with C++/CLI, so is there something I'm missing?

  • Generically creating objects in C#

    - by DrLazer
    What I am trying to do is load in objects from an XML save file. The problem is those objects are configurable by the user at runtime, meaning i had to use reflection to get the names and attributes of those objects stored in an XML file. I am in the middle of a recursive loop through the XML and up to the part where I need to create an object then thought ..... ah - no idea how to do that :( I have an array stuffed with empty objects (m_MenuDataTypes), one of each possible type. My recursive loading function looks like this private void LoadMenuData(XmlNode menuDataNode) { foreach (object menuDataObject in m_MenuDataTypes) { Type menuDataObjectType = menuDataObject.GetType(); if (menuDataObjectType.Name == menuDataNode.Name) { //create object } } } I need to put some code where my comment is but I can't have a big switch statement or anything. The objects in my array can change depending on how the user has configured the app.

  • Why won't this static_cast in C++ work?

    - by samoz
    When I try to use a static_cast to cast a double* to an int*, I get the following error: invalid static_cast from type ‘double*’ to type ‘int*’ Here is the code: #include <iostream> int main() { double* p = new double(2); int* r; r=static_cast<int*>(p); std::cout << *r << std::endl; } I understand that there would be problems converting between a double and an int, but why is there a problem converting between a double* and an int*?

  • login not working when changing from mysql to mysqli

    - by user1438647
    I have a code below where it logs a teacher in by matching it's username and password in the database, if correct, then log in, if incorrect, then display a message. <?php session_start(); $username="xxx"; $password="xxx"; $database="mobile_app"; $link = mysqli_connect('localhost',$username,$password); mysqli_select_db($link, $database) or die( "Unable to select database"); foreach (array('teacherusername','teacherpassword') as $varname) { $$varname = (isset($_POST[$varname])) ? $_POST[$varname] : ''; } ?> <form action="<?php echo htmlentities($_SERVER['PHP_SELF']); ?>" method="post" id="teachLoginForm"> <p>Username</p><p><input type="text" name="teacherusername" /></p> <!-- Enter Teacher Username--> <p>Password</p><p><input type="password" name="teacherpassword" /></p> <!-- Enter Teacher Password--> <p><input id="loginSubmit" type="submit" value="Login" name="submit" /></p> </form> <?php if (isset($_POST['submit'])) { $query = " SELECT * FROM Teacher t WHERE (t.TeacherUsername = '".mysqli_real_escape_string($teacherusername)."') AND (t.TeacherPassword = '".mysqli_real_escape_string($teacherpassword)."') "; $result = mysqli_query($link, $query); $num = mysqli_num_rows($result); $loged = false; while($row = mysqli_fetch_array($result)) { if ($_POST['teacherusername'] == ($row['TeacherUsername']) && $_POST['teacherpassword'] == ($row['TeacherPassword'])) { $loged = true; } $_SESSION['teacherforename'] = $row['TeacherForename']; $_SESSION['teachersurname'] = $row['TeacherSurname']; $_SESSION['teacherusername'] = $row['TeacherUsername']; } if ($loged == true){ header( 'Location: menu.php' ) ; }else{ echo "The Username or Password that you Entered is not Valid. Try Entering it Again."; } mysqli_close($link); } ?> Now the problem is that even if the teacher has entered in the correct username and password, it still doesn't let the teacher log in. When the code above was the old mysql() code, it worked fine as teacher was able to login when username and password match, but when trying to change the code into mysqli then it causes login to not work even though username and password match. What am I doing wrong?

  • Javascript error in Setting focus to a textbox inside a lightbox(Overlay) window.

    - by Rishabh Ohri
    Hi All, I have a textbox, a button and a "AdvancedSearch" link on my aspx page. On page load, the focus is set to the textbox. On click of the "AdvancedSearch" link, a lightbox(overlay) window will be opened. I want to set focus to a textbox present within this lightbox window. I am using javascript to achieve this. The code looks somewhat like this: if( element.type != "hidden" && element.style.display != "none" && !element.disabled ) { element.focus(); return; } when the lightbox window loads, i get a javascript error - "Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus" Any idea why this error is thrown and why it is not able to set focus to the textbox in the lightbox window? Thanks, Rishab.

  • Hide header if node body is empty - Drupal php snippet help

    - by Toxid
    Hello! I've made a content type for links, I'm trying to make a link directory. People only have to submit the link, description is voluntary. If no description is entered, I want the header that says "description" to disappear. The description field is the node body. Right now my snippet looks like this <?php if (!empty($node->body)) {?> <div class="field field-type-link field-field-link-archive"> <h3>Description</h3> <?php print $node->content['body']['#value'] ?></div> <?php }?> I expect this to check if node body is not empty, and if it isn't it'll print what's there. The problem is that the Description header is still printed out even if the node body is empty. Can anyone see what's wrong?

  • Repeating characters in VIM insert mode

    - by Cthutu
    Is there a way of repeating a character while in Vim's insert mode? For example, say I would like to insert 80 dashes, in something like emacs I would type: Ctrl+U 8 0 - The only way I know how to do it in VIM is to exit normal mode for the repeat argument, then go back into insert mode to type the dash, then exit to insert the actual dashes, AND then go back into insert mode to carry on typing. The sequence is a really long: <ESC> 8 0 a - <ESC> a It would be nice not to switch in and out of modes. Thanks

  • How to use GPS data like the double value returned by getLatitude()?

    - by Dan
    I have been searching quite a bit for an answer, but maybe I'm just not using the correct terminology. I am creating an app that will access a database to return a list of other users that are within a certain distance of the users location. I've never worked with this type of data, and I don't really know what the values mean. I'd like to do all the calculations on the backend with either MySQL or PHP. Currently, I am storing the latitude and longitude as doubles within the database. I can access them and store them, but I have no idea how I might be able to sort them based on distance. Perhaps I should be using a different type or some technique that is common in this area. TIA.

  • filter functions problem

    - by Adam
    I'm working on a search component for an app I'm working on and I needed to add some filters to it. I've found an example and got the first filter working fine. Now I'm trying to add a second filter I'm running into problems... In the example I found they use filterFunctions, but I only get an option for filterFunction, why is that? Here's the example code productsCollection.filterFunctions = [ filterByPrice, filterByType, filterByCondition, filterByVendor ] And this is what I'm trying acData.filterFunction = [filterByStatus, filterByDate] but with this code I get the following error message - 1067: Implicit coercion of a value of type Array to an unrelated type Function. Why am I getting this error and how would I go about add multiple filters to my Array Collection? Thanks!

  • .htaccess redirect question

    - by russp
    I have a slight problem with .htaccess redirect. I have a dynamic site with 2 levels of variables - content="type -(alpha)" and ID="number" but this is very not seo friendly what I really would like to create is a rewrite rule that generates a "friendly" url for serach engines & users alike. Very much like WordPress does. Each ID is already unique (obviously) and on creation is creating a unique "permalink" field so for example ID=1 has a "permalink field" as "2009/10/27/page title" and ID=100 would be "2010/10/27 page title". I would like folder/wall.php?content=type&ID=number to redirect to folder/permalink.php/html/htm (don't mind a non dynamic extension) Any clues? - this is not right (I know) but it also "breaks" my css file RewriteEngine On RewriteRule wall/content/(.*)/ID/(.*)/ wall.php?content=$1&ID=$2 RewriteRule wall/content/(.*)/ID/(.*) wall.php?content=$1&ID=$2

  • visual studio 2008 keyboard gets locked when editing source controlled files

    - by Rama
    Hi, I am facing a strange issue with editing source controlled files (especially aspx files) using visual studio 2008. when I check out and edit the file, I can edit fine for few seconds and after that keyboard gets locked and I can't type anything (it doesn't affect the files not added to source control). as soon it is locked, if I try to type, the focus shifts to solution explorer and other windows and sometimes it freezes and doesn't respond at all. I tried uninstalling and reinstalling visual studio, reinstalling the source control plug-in. none of it worked. not sure if it is my machine or my profile. Please help if you have any clues. I can't see any other solution for this except rebuilding the machine Thanks, Rama

  • Is there a way to use a dictionary or xml in the Application Settings?

    - by Shimmy
    I have to store a complex type in the application settings. I thought that storing it as XML would work best. The problem is I don't know how store XML. I prefer to store it as a managed XML rather than using just a string of raw XML having to parse it on each access. I managed to set the Type column of the setting to XDocument, but I was unable to set its value. Is there a way to use XDocument or XML in application settings? Update I found a way, simply by editing the .settings file with the xml editor. I changed it to a custom serializable dictionary, but I get the following error when I try to access the setting-property (I set it to a serialized representation of the default value). The property 'Setting' could not be created from it's default value. Error message: There is an error in XML document (1, 41). Any ideas will be appreciated.
