  • JQuery get element from a string problem

    - by SLC
    Sorry for such a simple question but I can't seem to find the solution. I am trying to fade in and out some divs. Divs have an ID of "div1", "div2", "div3". My code is: var Divs = new Array("div1", "div2", "div3"); I want to fade out one div and then fade in the next on top of it. I have a setinterval that runs every 5 seconds and checked it works. Inside it is this code: $(Divs[1]).fadeOut(1000); $(Divs[2]).fadeIn(1000); However nothing happens when the timer method is ran. Any ideas?

  • how to use ByteArrayOutputStream and DataOutputStream simultaneously (Java)

    - by Manuel
    Hi! I'm having quite a problem here, and I think it is because I don't understand very much how I should use the API provided by Java. I need to write an int and a byte[] into a byte[] I thought of using a DataOutputStream to solve the data writing with writeInt(int i) and write(byte[] b), and to be able to put that into a byte array, I should use ByteArrayOutputStream's method toByteArray(). I understand that this classes use the Wrapper pattern, so I had two options: DataOutputStream w = new DataOutputStream(new ByteArrayOutputStream()); or ByteArrayOutputStream w = new ByteArrayOutputStream(new DataOutputStream()); but in both cases, I "loose" a method. in the first case, I can't access the toByteArray method, and in the second, I can't access the writeInt method. How should I use this classes together?

  • Creating methods with infinite overloads ? (.NET)

    - by MarceloRamires
    In C# you can do this: foo = string.Format("{0} {1} {2} {3} ...", "aa", "bb", "cc" ...); This method Format() accepts infinite parameters, being the first one how the string should be formatted and the rest are values to be put in the string. Today I've come to a situation where I had to get a set of strings and test them, then I remembered this language functionality, but I had no clue. After a few unsuccessful web searches, I've realised it would be more prudent to just get an array, which didn't make me quite satisfied. Q: How do I make a function that accepts infinite parameters? And how do I use it ?

  • Any way to break if statement in PHP?

    - by Usman
    Is there any command in PHP to stop executing the current or parent if statement, same as break or break(1) for switch/loop. For example $arr=array('a','b'); foreach($arr as $val) { break; echo "test"; } echo "finish"; in the above code PHP will not do echo "test"; and will go to echo "finish"; I need this for if $a="test"; if("test"==$a) { break; echo "yes"; // I don't want this line or lines after to be executed, without using another if } echo "finish"; I want to break the if statement above and stop executing echo "yes"; or such codes which are no longer necessary to be executed, there may be or may not be an additional condition, is there way to do this?

  • File upload with tdo-miniforms not working

    - by user338109
    I am using the TDO-miniforms plugin for wordpress. I have a form set up that lets the user submit files. The files are successfully uploaded to the tmp-folder, but once the post is created they are not copied into the allocated post folder. The only thing that is created in the folder with a post id is a file called array. It seems like the file holds the binary data of the uploaded files. The “correct” urls are appended to the post content I am running wordpress 2.9.2 on snow leopard using Mamp.

  • php adding value to session

    - by antikbd
    I am trying to implement a 'shopping cart' where, if the 'Add to Cart' has been clicked, the respective item is either added to the cart or incremented by one if already present. However, the following code isn't working and giving me a "Cannot use a scalar value as an array" error. Any help would be highly appreciated. if (isset($_POST['fan']) && ($_POST['fan']=="Add to Cart")) { if (($_SESSION['cart']['fan']==0) || (!isset($_SESSION['cart']['fan']))) { $_SESSION['cart']['fan']=1; } else { $_SESSION['cart']['fan']++; } }

  • Is new int[10]() valid c++?

    - by Naveen
    While trying to answer this question I found that the code int* p = new int[10](); compiles fine with VC9 compiler and initializes the integers to 0. So my questions are: First of all is this valid C++ or is it a microsoft extension? Is it guaranteed to initialize all the elements of the array? Also, is there any difference if I do new int; or new int();? Does the latter guarantee to initialize the variable?

  • Switching from php to python

    - by ts
    Hello I am trying to make a list of things which can be difficult/surprising to someone who is changing language from PHP to Python. so far i have rather short list: forget require / include, learn import (this was most difficult to me - to understand package - module - class - object hierarchy and its mapping to filesystem) you can't just upload file on server to have webpage (-mod_python, wsgi etc) learn the python way for use variable class names (new $class() vs import + getattr) / operator in python 2.x and all float-related horrors those were difficult to me, it takes few days before mind adapts a new paradigm after i found that there is few other areas which could be challenging for someone with (too) many years of php: everything is an object you have to live with exceptions array vs list, set, dictionary, tuple ... learn (effective) list comprehensions learn generators any other ideas / personal experiences ?

  • fields_for to stop pluralizing.

    - by Dmitriy Likhten
    I have a fields_for tag, where I specify the prefix (lets say for some good reasons), and this is supposed to represent a one-to-one relationship. I am trying to represent a relationship widget has_many thingamagigs thingamagig has_one whatchamacallit The field_for code is: fields_for "widgt[thingamagigs_attributes][][whatchamacallit_attributes]", thingamagig.whatchamacallit do |x| which generates names (wrongly): widget[thingamagigs_attributes][][whatchamacallit_attributes][][value] The better solution would be t.fields_for :whatchamacallit do |x| where t = fields_for the thingamagig... However if I do that, the following names are generated widgt[thingamagigs_attributes][whatchamacallit_attributes][] which is completely wrong as all other fields for a thingamagig is... widgt[thingamagigs_attributes][][name] So in all cases I am screwed. The original field_for using a string cannot be used with accepts_nested_attributes_for :whatchamacallit since whatchamacallit is a singular relationship and an object is expected not an array. The second fields_for will simply not work because rails cannot parse the params object correctly. Is there a way to tell the first forms_for to not add the [] after [whatchamacallit_attributes] in all field names?

  • Getting MATLAB variable (string) from C

    - by Hamming
    Hi! I'm writing a small C application that launchs a Matlab script (.m file). I need to exchange some variables and I don't know how to get an array of chars that exists in Matlab. I'm doing something like this: enter code here result = engGetVariable(ep,"X"); if (!result) { printf ("Error..."); exit -1; } int n = mxGetN(result); char *varx = NULL; memcpy(varx, mxGetData(result),n*sizeof(char)); It doesn't work. Does someone know how to get a Matlab string in C? I've read Matlab documentation about engGetVariable() and the provided example but any of this things clarify me.

  • Is it a good idea to include a large text variable in compiled code?

    - by gladman
    I am writing a program that produces a formatted file for the user, but it's not only producing the formatted file, it does more. I want to distribute a single binary to the end user and when the user runs the program, it will generate the xml file for the user with appropriate data. In order to achieve this, I want to give the file contents to a char array variable that is compiled in code. When the user runs the program, I will write out the char file to generate an xml file for the user. char* buffers = "a xml format file contents, \ this represent many block text \ from a file,..."; I have two questions. Q1. Do you have any other ideas for how to compile my file contents into binary, i.e, distribute as one binary file. Q2. Is this even a good idea as I described above?

  • Why does set key not do anything in AES/SymmetricAlgorithm?

    - by acidzombie24
    This MESSED ME UP hard. I thought i was setting the key but i was not. No exceptions, nothing happen except bad results. Why is there a setter if everything is ignored and no exceptions are thrown when i attempt to write? What is the point of the setter on the Keys property? When i do the below Key value are not changed. After an hour when i realize what was happening i wrote the loop to verify. I also tried aes.Key[0] = val; var b = val == aes.Key[0]; (and messed with it in immediate mode). Why does it have this behavior? Array.Copy(myKey, aes.Key, aes.Key.Length); int i = 0; foreach (var v in aes.Key) { var b = myKey[i++] == v; if (!b) b = b; }

  • Methods for breaking up content client-side into multiple "pages"

    - by Tom Genoni
    I have a long HTML text-only article formatted with paragraph tags. What I'd like to do is break this content into N number of divs so that I can create individual pages. So, for instance, on an iPad/iPhone, instead of reading one long page the user could swipe right/left to navigate to pages. My initial javascript attempts have been somewhat convoluted: creating an array of the text, measuring line-heights, device window heights, adding closing/opening paragraph tags and the end/beginning of pages. Thoughts on a good way to approach this? I will not have access to server-side processing, this has to be a client-side solution.
