  • How to not allow parts of sortable jquery list to move?

    - by sanpell
    I made a sortable list: <ul> <li class="line"><a href="#" class="food">milk</a></li> <li class="line"><a href="#" class="food">eggs</a></li> <li class="line"><a href="#" class="food">cheese</a></li> </ul> However, I want to make everything with class food not draggable. Since they are links, sometimes when people click them, they accidently reorder the list. Does anyone know how to make just the "food" class items not "draggable"?

  • Uncompressing zlib data using boost::iostreams::filtering_streambuf trouble

    - by GuitaringEgg
    I'm trying to write a small class that will load the chunk data from part of a minecraft world file. I'm to the point where I have stored some data in a char array which was compressed with zlib and need to decompress it. I'm trying to use the boost filtering_streambuf to do this. char * rawChunk = new char[length - 1]; // Load chunk data stringstream ssRawChunk(rawChunk); boost::iostreams::filtering_istream in; in.push(boost::iostreams::zlib_decompressor()); in.push(ssRawChunk); stringstream ssOut; boost::iostreams::copy(in, ssOut); My problem is that rawChunk contains null data, so when coping data from (char*) rawChunk to (stringstream) ssRawChunk, it terminates at ~257 instead of the expected length 2154. Is there any way to use filtering_streambuf without stringstream to allow for null data or is there a way to stop stringstream to not terminate on null data?

  • How to add children of an ItemsControl where the children should decide their own position in Wpf?

    - by code-zoop
    Hey all I am using a wpf slider to display the time line in a video player. I need to add an ItemControl of some sort on top of this so that I can add buttons on the time line on certain positions in the time line (the buttons will hold their own position relative to the parent ItemsControl). What ItemsControl container should I use where I can add child elements that know their own position (based on their timecode)? I have looked at the different ItemsControls in Wpf, and it looks like all of them have a certain way to stack their children (Horizontal or vertical one after another)! And to add some more complexity, How can the positioning of the children be relative to the width of the parent ItemsControl? This way scaling up and down the ItemsContol will reposition the children! Thanks

  • Simple javascript problem in ie6 and ie7

    - by Jeff Lamb
    I have a very simple function that takes a list of comma separated (x,y) points and imports them into a graph. I have FF, Chrome and IE8 installed. I use IETester to test for IE6 and IE7. // Import Data this.Import = function(data) { alert("Data in: "+data); var d; // Make sure the first and the last are start/ending parenthesis if ( (data[0] != '(') || (data[data.length-1] != ')') ) { alert("After if: "+data[0]+" "+data[data.length-1]); return false; } ... In Chrome, FF and IE8, I don't see the "After if:" alert. In IE6 and IE7, I see the following two alerts: Data in: (52,16),(100,90) After if: undefined undefined The "Data in" alert matches in all browsers. Any ideas?

  • Jagged Edge Arrays in PHP

    - by chriscct7
    I want to store some data in (I guess a semi-2, semi-3d array) in PHP (5.3) What I need to do is store data about each floor like this: Floor Num of Spots Handicap Motorcyle Other 1 100 array(15,16,17) array (47,62) array (99,100) 2 100 array(15,16,17) array (47,62) array (99,100) and on The problem is, is if the Handicap+Motorcyle+Other were ints, I could just store the data in a 2d array. However, they aren't. So I was thinking I could make something almost like a 3D array, with the first two columns only being in 2D. The other thought I had was making a 2D array and for columns 3,4, and 5 instead of saving as array(15,16) //save like 1516 And then split at two digits (1 digit array numbers would be prefaced with a 0). However, I am wondering about the limit of the length of a string, because if I decide to move to a 3 digit length number in the array, like array(100, 104), and I need to store alot of numbers, I am thinking I am going to quickly exceed the max.

  • Java: matching two different type of array

    - by sling
    Hi, I am doing a password login that requires me to match two array: User and Pass. If user key in "mark" and "pass", it should show successfully. However I have trouble with the String[] input = pass.getPassword(); and the matching of the two arrays. String[] User = {"mark", "susan", "bobo"}; String[] Pass = {"pass", "word", "password"}; String[] input = pass.getPassword(); if(Pass.length == input.length && user.getText().equals(User)) { lblstat.setForeground(Color.GREEN); lblstat.setText("Successful"); } else { lblstat.setForeground(Color.RED); lblstat.setText("Failed"); }

  • Should I use uint in C# for values that can't be negative?

    - by Johannes Rössel
    I have just tried implementing a class where numerous length/count properties, etc. are uint instead of int. However, while doing so I noticed that it's actually painful to do so, like as if no one actually wants to do that. Nearly everything that hands out an integral type returns an int, therefore requiring casts in several points. I wanted to construct a StringBuffer with its buffer length defaulted to one of the fields in that class. Requires a cast too. So I wondered whether I should just revert to int here. I'm certainly not using the entire range anyway. I just thought since what I'm dealing with there simply can't be negative (if it was, it'd be an error) it'd be a nice idea to actually use uint. P.S.: I saw this question and this at least explains why the framework itself always uses int but even in own code it's actually cumbersome to stick to uint which makes me think it apparently isn't really wanted.

  • loading data from file into 2d array

    - by Chris
    I am just starting with perl and would like some help with arrays please. I am reading lines from a data file and splitting the line into fields: open (INFILE, $infile); do { my $linedata = <INFILE>; my @data= split ',',$linedata; .... } until eof; I then want to store the individual field values (in @data) in and array so that the array looks like the input data file ie, the first "row" of the array contains the first line of data from INFILE etc. Each line of data from the infile contains 4 values, x,y,z and w and once the data are all in the array, I have to pass the array into another program which reads the x,y,z,w and displays the w value on a screen at the point determined by the x,y,z value. I can not pas the data to the other program on a row-by-row basis as the program expects the data to in a 2d matrtix format. Any help greatly appreciated. Chris

  • Batch file to wait for other program to load/initialize, then execute command?

    - by Jason N
    I need some assistance writing what should be a fairly basic .BAT file. I load my main program, but that program takes ~20secs to load and be initialized. I have another command-line API I can execute to interact with this above program, but obviously until the above program is loaded and initialized there's no point in trying. If the program isn't running the command-line API returns a string stating exactly this - otherwise it just works and exits. Easy. So I want to wait until the above is loaded/initialized before firing my API command(s) at it. I could place a sleep/wait in there, but I want something more solid. The ~20sec wait is not necessarily consistent. Any way to execute the command-line API over and over until the response is satisfactory, then exit? J

  • Fluent-NHibernate - Component property attributes ignored by Convention

    I have a component with a number of properties that have various attributes Normally when these attributes are added to a plain old domain object they are picked up by my custom AttributeConventions. For the Component properties they are not. Is there some extra wiring needed for these? e.g. public class Component { [Length(Max=50)] public virtual string Name {get; set;} } public class MyClass { public virtual Component Component {get; set;} [Length(Max=50)] public virtual string Color {get; set;} } I get a table MyClass with columns Color & ComponentName Color is an nvarchar(50) whilst ComponentName is an nvarchar(255) (the default)

  • VARCHAR does not work as expected in Apache Derby

    - by Tom Brito
    I'm having this same problem: How can I truncate a VARCHAR to the table field length AUTOMATICALLY in Derby using SQL? To be specific: CREATE TABLE A ( B VARCHAR(2) ); INSERT INTO A B VALUES ('1234'); would throw a SQLException: A truncation error was encountered trying to shrink VARCHAR '123' to length 2. that is already answered: No. You should chop it off after checking the meta-data. Or if you don't wanna check the meta-data everytime, then you must keep both your code and database in sync. But thats not a big deal, its a usual practice in validators. but my doubt is: isn't VARCHAR suppose to variate its size to fit the data? What's wrong with apache derby's VARCHAR?

  • Exception design: Custom exceptions reading data from file?

    - by User
    I have a method that reads data from a comma separated text file and constructs a list of entity objects, let's say customers. So it reads for example, Name Age Weight Then I take these data objects and pass them to a business layer that saves them to a database. Now the data in this file might be invalid, so I'm trying to figure out the best error handling design. For example, the text file might have character data in the Age field. Now my question is, should I throw an exception such as InvalidAgeException from the method reading the file data? And suppose there is length restriction on the Name field, so if the length is greater than max characters do I throw a NameTooLongException or just an InvalidNameException, or do I just accept it and wait until the business layer gets a hold of it and throw exceptions from there? (If you can point me to a good resource that would be good too)

  • How can I skip the current item and the next in a Python loop?

    - by uberjumper
    This might be a really dumb question, however I've looked around online, etc. And have not seen a solid answer. Is there a simple way to do something like this? lines = open('something.txt', 'r').readlines() for line in lines: if line == '!': # force iteration forward twice line.next().next() <etc> It's easy to do in C++; just increment the iterator an extra time. Is there an easy way to do that in Python? I would just like to point, out the main purpose of this question is not about "reading files and such" and skipping things. I was more looking for C++ iterator style iteration. Also the new title is kinda dumb, and i dont really think it reflects the nature of my question.
