  • PHP: Filling in the 'gaps' in an array

    - by aboved
    Hey gurus, I've got a php array (obtained through checkbox values in a form - as you know checkboxes only show up in the _POST variable when they are not set). Array ( [2] => 0,2 [3] => 0,3 ) I need a way to 'fill in' the gaps between the range 0-5. So above would look like (filling the empty spaces with '-1'. I tried array_merge() with an array filled with '-1' but that didn't work. Array ( [0] => -1 [2] => 0,2 [3] => 0,3 [4] => -1 [5] => -1 ) I think I may have gone down the wrong road with the problem I am trying to solve, but I have put too much time into this solution to back out - a feeling I am sure most of you are familiar with(!) Cheers!

  • Declaring pointers; asterisk on the left or right of the space between the type and name?

    - by GenTiradentes
    I've seen mixed versions of this in a lot of code. (This applies to C and C++, by the way.) People seem to declare pointers in one of two ways, and I have no idea which one is correct, of if it even matters. The first way it to put the asterisk adjacent the type name, like so: someType* somePtr; The second way is to put the asterisk adjacent the name of the variable, like so: someType *somePtr; This has been driving me nuts for some time now. Is there any standard way of declaring pointers? Does it even matter how pointers are declared? I've used both declarations before, and I know that the compiler doesn't care which way it is. However, the fact that I've seen pointers declared in two different ways leads me to believe that there's a reason behind it. I'm curious if either method is more readable or logical in some way that I'm missing.

  • Setfocus to textbox from JavaScript after just creating the textbox with JavaScript?

    - by Scott
    So I just created a textbox with JavaScript like this: EDIT: Added the len variable var len = tbl.rows.length; var rtb = tbl.insertRow(len); var cName = rtb.insertCell(0); var cDis = rtb.insertCell(1); var cDur = rtb.insertCell(2); cName.innerHTML = '<input type="text" name="tbName1' + len + '" value="' + selected_text + '" >'; cDis.innerHTML = '<input type="text" name="tbDis1' + len + '" id="tbDis1' + len + '" >'; cDur.innerHTML = '<input type="text" name="tbDur1' + len + '" >'; var txtBox = document.getElementById('tbDist1' + len); txtBox.focus(); EDIT:Changed the second to last line. Still get this error: txtBox is null txtBox.focus(); The last line isn't working. After I create the textbox, I can't set focus to it. Is there any way of doing so?

  • The Elegant way to handle Cyclic Event in Java ??

    - by dex
    Hi fellows, i think this not a specific problem to me; everybody might have encountered this issue before. To properly illustrate it, here's a simple UI: As you can see, those two spinners are controlling a single variable -- "A". The only difference is that they control it using different views. If i change the top spinner, "A" will be changed and the bottom spinner's value will also be updated accordingly. However, updating the bottom spinner's call (such as setValue) will also trigger another event instructing the top spinner to update based on the bottom spinner's value. Thus creates a bad cycle which can eventually cause a StackOverFlow exception. My previously solution is kinda cumbersome: i placed a guarding boolean to indicate whether the 2nd updating call should be performed. Now i'd like to ask "how can i handle such situation elegantly?" thx

  • Loading...Please wait for UIWebView - iPhone

    - by niha7229
    Hi guys, In Safari and other browsers, there is a bar that would indicate the percentage of the loading progress, and I, myself, trying to implement something similiar on iPhone, when loading some content in UIWebView, I would like the app to indicate the percentage of the page being loaded. I tried some google search and realize we could use NSURLConnection to read only the header and get the Content-Length ( but don't know how to, I read the Apple's NSURLConnection docs but probably I missed something ... ). And the size ( kb ) which UIWebView had loaded, seem like UIWebView don't support it for the public API... I hope this would be complete in some other ways than I thought, so if you have any ideas, please throw it out, thanks for your patient reading. P.S : I could just show an Activities Indicator for users with the long loading progress actions of the UIWebView but I just want to go further with the loading percentage bar :). Regards.

  • How Pick a Column Value from a ListView Row - C#.NET

    - by peace
    How can i fetch the value 500 to a variable from the selected row? One solution would be to get the row position number and then the CustomerID position number. Can you please give a simple solution. SelectedItems means selected row and SubItems means the column values, so SelectedItem 0 and SubItem 0 would represent the value 500. Right? This is how i populate the listview: for (int i = 0; i < tempTable.Rows.Count; i++) { DataRow row = tempTable.Rows[i]; ListViewItem lvi = new ListViewItem(row["customerID"].ToString()); lvi.SubItems.Add(row["companyName"].ToString()); lvi.SubItems.Add(row["firstName"].ToString()); lvi.SubItems.Add(row["lastName"].ToString()); lstvRecordsCus.Items.Add(lvi); }

  • const read only local copies

    - by robUK
    Hello gcc 4.4.4 c89 I am just wondering is it worth passing a const into a function. i.e. void do_something(const char *dest, const int size) The size is a read-only so I don't want to change it. However, some developers never have this as const has it is a local copy that is being used. The pointer is const as you can change the value in the calling routine. I always have a const on read-only local copies, as it confirms to anyone reading my code that it is a read-only variable. And also, when coding I don't make the mistake of changing it without realizing. Many thanks for any suggestions,

  • word ladder in python

    - by user365523
    I'm trying to create a word ladder program in python. I'd like to generate words that are similar to a given word. In c++ or java, I would go through each valid index in the original string, and replace it with each letter in the english alphabet, and see if the result is a valid word. for example (pseudocode) for (int i = 0; i < word.length(); i++) { for (every character c in the alphabet) { change the letter of word at index i to be c. if the result is a valid word, store it in a list of similar words } } . However, this doesn't seem like a very "python" way of doing things. How would I approach this problem in python?

  • How to add response headers based on Content-type, or getting Content-type before the response is co

    - by Bozho
    I want to set the Expires header for all image/* and text/css. I'm doing this in a Filter. However: before calling chain.doFilter(..) the Content-type is not yet "realized" after calling chain.doFilter(..) the Content-type is set, but so is content-length, which forbids adding new headers (at least in Tomcat implementation) I can use the extensions of the requested resource, but since some of the css files are generated by richfaces by taking them from inside jar-files, the name of the file isn't x.css, but is /xx/yy/zz.xcss/DATB/.... So, is there a way to get the Content-type before the response is committed.

  • PagedDataSource does not support serialization - how can I enforce this ?

    - by Darkyo
    Sounds like I want to override a physics law, but at least it is the most reasonnable solution, cpu / HDD and Ram effective for my asp.net project. In fact, I got a pageddataSource and a customDataReader that supports paginated data. The truth is my data are in a viewstate variable, because it is re-used in an update panel. When I intend to use it into my pageddatasource, asp.net 3.5 kills me with a System.Web.UI.WebControls.PagedDataSource' in Assembly 'System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' is not marked as serializable. cool exception... So I'd rather not offend newton because I know he'll always win, but I would need some help to enforce this pagedDataSource law, that seems so unbelievable, except if someone has an explanation.

  • Initialize a static member ( an array) in C++

    - by Jimmy zhang
    I intended to create a class which only have static members and static functions. One of the member variable is an array. Would it be possible to initialize it without using constructors? I am having lots of linking errors right now... Class A{ public: static char a[128]; static void do_something(); } How would you initialize a[128]? Why can't I initialize a[128] by directly specifying its value like in C? a[128={1,2,3,...};

  • Problem with debug watch in Visual Studio with yield return enumerator methods

    - by Stuart
    I have a method which returns an IEnumerable<> which it builds up using the yield return syntax: public IEnumerable<ValidationError> Validate(User user) { if (String.IsNullOrEmpty(user.Name)) { yield return new ValidationError("Name", ValidationErrorType.Required); } [...] yield break; } If I put a breakpoint in the method, I can step over each line, but if I try to use the Watch or Immediate windows to view the value of a variable I get this error: Cannot access a non-static member of outer type '[class name].Validate' via nested type '[class name]' Does anyone know why this is and how I can get around it?

  • View a SYS.XMLTYPE returned from an Oracle function, using PL/SQL

    - by caerphilly
    I have an Oracle function that dynamically creates an XML document, and returns it in a SYS.XMLTYPE value. I want to run a query from SQL Developer that calls that function and prints the document (either via a select, or dbms_output - I don't care). But all the examples/documentation seem to refer to querying XML columns in tables, and I can't seem to get the syntax right for my particular usage. I'd like something like this: declare x SYS.XMLTYPE; begin x := my_package.my_function(); select x.getclobval() from x; -- doesn't work! end; How can I print out the value of the XML type variable 'x' in the above code?

  • Compiler error when casting to function pointer

    - by detly
    I'm writing a bootloader for the PIC32MX, using HiTech's PICC32 compiler (similar to C90). At some point I need to jump to the real main routine, so somewhere in the bootloader I have void (*user_main) (void); user_main = (void (*) (void)) 0x9D003000; user_main(); (Note that in the actual code, the function signature is typedef'd and the address is a macro.) I would rather calculate that (virtual) address from the physical address, and have something like: void (*user_main) (void); user_main = (void (*) (void)) (0x1D003000 | 0x80000000); user_main(); ...but when I try that I get a compiler error: Error #474: ; 0: no psect specified for function variable/argument allocation Have I tripped over some vagarity of C syntax here? This error doesn't reference any particular line, but if I comment out the user_main() call, it goes away. (This might be the compiler removing a redundant code branch, but the HiTech PICC32 isn't particularly smart in Lite mode, so maybe not.)

  • PostgreSQL like + Hibernate problem

But after executing I'm getting: org.hibernate.QueryException: Not all named parameters have been set: [:TEXT] [select * from news WHERE lower(ID::TEXT) LIKE '%5%' Exception. Looks like hibernate parse my convert exp as parameter. Any help is appreciated. Thanks.

  • sizeToFit label voids align right / set minimum width of label

    - by Deco
    Here is my code I am using to make a label (which contains content of an unknown length) the correct height for the content. (lines is equal to 0) myLabel.text =[NSString stringWithFormat:@"%@", myLabelContent]; myLabel.frame = CGRectMake(myLabel.frame.origin.x, myLabel.frame.origin.y, myLabel.frame.size.width, 800); [myLabel sizeToFit]; The only problem is, it is resizing the width as well as the height. I have two labels side by side, one aligned left, one aligned right. The left aligned one works fine. However, the right aligned one becomes intended (from the right). Because of its width resize, the content always starts at the origin.x position (in effect) because the label is made to be the shortest width required. I hope that makes sense. Is there a way to override or reset the width after auto resize had solved the height problem, or set a minimum width for the label? Many Thanks in advance, Deco

  • How to count toggled buttons in jqueryui after a click event.

    - by SystemicPlural
    I need to count how many buttons are toggled using the jqueryui checkbox button option - .buttonset(). This needs to happen when a button is toggled. I added a unique class to the labels before applying the button set and have set a click event on it. It fires fine, however it is firing before the jqueryui has processed the click so the result is out of date. How do I apply the click event after jqueryui has done its job? $(".button-set").click(function(){ var selected = $("#offer_list_4 label[aria-pressed=true]").length; // out of date });

  • Using Jquery $getJSON How do I dynamically create data for the [data] parameter after Url param?

    - by Breadtruck
    I have no problems getting the Json to work and parse the json return. I was just wondering how I could build a dynamic "whatever data is" and stick it into [data] to pass my parameters from there and not manually append them to the url. From jquery website example: $.getJSON("test.js", { name: "John", time: "2pm" }, function(json){ alert("JSON Data: " + json.users[3].name); }); I thought I could build a string ( which doesn't make sense anyway ) and drop it inside the { }, but I obviously don't understand that part. name: isn't a string and you can't put a variable in that part, so how would I dynamically put items into whatever [data] is.

  • I need to order a list that is dependant on another list. how to change both lists?

    - by Ben Fossen
    I have a Matlab program that generates a list x = 6.1692 8.1863 5.8092 8.2754 6.0891 the program also outputs another list aspl = 680 637 669 599 693. The two lists are on equal length and the first element in list x is related to the first element in list aspl. I need to graph the two lists but want list aspl to be in order from smallest to largest. How would I go about doing this? If I need to move the first element in aspl to position 4 in the list, then the first element of list x also needs to be moved to position 4 in list x. The numbers above are not important they are just examples, the actual program generates hundereds of numbers. for example x = 6.1692 8.1863 5.8092 8.2754 initially aspl = 680 637 669 599 693 after changing aspl to ascending order this is how x should look. x = 5.8092 8.1863 5.8092 6.1692 8.2754 aspl = 599 637 669 680 693
