  • Perl array and hash manipulation using map

    - by somebody
    I have the following test code use Data::Dumper; my $hash = { foo => 'bar', os => 'linux' }; my @keys = qw (foo os); my $extra = 'test'; my @final_array = (map {$hash->{$_}} @keys,$extra); print Dumper \@final_array; The output is $VAR1 = [ 'bar', 'linux', undef ]; Shouldn't the elements be "bar, linux, test"? Why is the last element undefined and how do I insert an element into @final_array? I know I can use the push function but is there a way to insert it on the same line as using the map command? Basically the manipulated array is meant to be used in an SQL command in the actual script and I want to avoid using extra variables before that and instead do something like: $sql->execute(map {$hash->{$_}} @keys,$extra);

  • Simple graphics import and manipulation

    - by gnuboi
    What do I need to do something like this? User builds a diagram and tags certain boxes and circles with text. User imports diagram into my program. My program processes the tagged boxes and circles and fills them with different colors. My program exports color-filled diagram. So the questions are... What graphics format supports tag-able boxes and circles? What existing application should I recommend users to use to produce diagrams in the above format? Would this graphics format be very easily readable in code to do things like reading tags and coloring in the associated boxes and circles? Free / open source libraries and apps are desired as this would be for academic use. Thank you!

  • Bitmap manipulation as a referenced object

    - by John Maloney
    I am working with a Bitmap object that I add annotations or copyright material to the image and then return the modified bitmap. My problem is that the Bitmap won't hold the changes made to it as it moves along the chain. I am treating it as a reference type and would assume that as it gets passed to each class it would carry the changes made to it. I have verified that the code inside of the MarkImage() classes does function, but which ever one gets called last is the one that has changes. Public Shared Function GetImage(ByVal imageDef As IImageDefinition) As Bitmap Dim image As Bitmap = Drawing.Image.FromFile(imageDef.Path) If Not imageDef.Authorization.IsAllowed(AuthKeys.CanViewWithoutCopyright) Then image = New MarkCopyrightImage(image).MarkImage() End If If Not imageDef.Authorization.IsAllowed(AuthKeys.CanViewWithoutAnnotations) Then image = New MarkAnnotateImage(image).MarkImage() End If Return image End Function How do I write changes to a bitmap object and then pass that object to another class while maintaining the changes? Answers in C# or VB are fine? Thanks

  • Linked List manipulation, issues retrieving data c++

    - by floatfil
    I'm trying to implement some functions to manipulate a linked list. The implementation is a template typename T and the class is 'List' which includes a 'head' pointer and also a struct: struct Node { // the node in a linked list T* data; // pointer to actual data, operations in T Node* next; // pointer to a Node }; Since it is a template, and 'T' can be any data, how do I go about checking the data of a list to see if it matches the data input into the function? The function is called 'retrieve' and takes two parameters, the data and a pointer: bool retrieve(T target, T*& ptr); // This is the prototype we need to use for the project "bool retrieve : similar to remove, but not removed from list. If there are duplicates in the list, the first one encountered is retrieved. Second parameter is unreliable if return value is false. E.g., " Employee target("duck", "donald"); success = company1.retrieve(target, oneEmployee); if (success) { cout << "Found in list: " << *oneEmployee << endl; } And the function is called like this: company4.retrieve(emp3, oneEmployee) So that when you cout *oneEmployee, you'll get the data of that pointer (in this case the data is of type Employee). (Also, this is assuming all data types have the apropriate overloaded operators) I hope this makes sense so far, but my issue is in comparing the data in the parameter and the data while going through the list. (The data types that we use all include overloads for equality operators, so oneData == twoData is valid) This is what I have so far: template <typename T> bool List<T>::retrieve(T target , T*& ptr) { List<T>::Node* dummyPtr = head; // point dummy pointer to what the list's head points to for(;;) { if (*dummyPtr->data == target) { // EDIT: it now compiles, but it breaks here and I get an Access Violation error. ptr = dummyPtr->data; // set the parameter pointer to the dummy pointer return true; // return true } else { dummyPtr = dummyPtr->next; // else, move to the next data node } } return false; } Here is the implementation for the Employee class: //-------------------------- constructor ----------------------------------- Employee::Employee(string last, string first, int id, int sal) { idNumber = (id >= 0 && id <= MAXID? id : -1); salary = (sal >= 0 ? sal : -1); lastName = last; firstName = first; } //-------------------------- destructor ------------------------------------ // Needed so that memory for strings is properly deallocated Employee::~Employee() { } //---------------------- copy constructor ----------------------------------- Employee::Employee(const Employee& E) { lastName = E.lastName; firstName = E.firstName; idNumber = E.idNumber; salary = E.salary; } //-------------------------- operator= --------------------------------------- Employee& Employee::operator=(const Employee& E) { if (&E != this) { idNumber = E.idNumber; salary = E.salary; lastName = E.lastName; firstName = E.firstName; } return *this; } //----------------------------- setData ------------------------------------ // set data from file bool Employee::setData(ifstream& inFile) { inFile >> lastName >> firstName >> idNumber >> salary; return idNumber >= 0 && idNumber <= MAXID && salary >= 0; } //------------------------------- < ---------------------------------------- // < defined by value of name bool Employee::operator<(const Employee& E) const { return lastName < E.lastName || (lastName == E.lastName && firstName < E.firstName); } //------------------------------- <= ---------------------------------------- // < defined by value of inamedNumber bool Employee::operator<=(const Employee& E) const { return *this < E || *this == E; } //------------------------------- > ---------------------------------------- // > defined by value of name bool Employee::operator>(const Employee& E) const { return lastName > E.lastName || (lastName == E.lastName && firstName > E.firstName); } //------------------------------- >= ---------------------------------------- // < defined by value of name bool Employee::operator>=(const Employee& E) const { return *this > E || *this == E; } //----------------- operator == (equality) ---------------- // if name of calling and passed object are equal, // return true, otherwise false // bool Employee::operator==(const Employee& E) const { return lastName == E.lastName && firstName == E.firstName; } //----------------- operator != (inequality) ---------------- // return opposite value of operator== bool Employee::operator!=(const Employee& E) const { return !(*this == E); } //------------------------------- << --------------------------------------- // display Employee object ostream& operator<<(ostream& output, const Employee& E) { output << setw(4) << E.idNumber << setw(7) << E.salary << " " << E.lastName << " " << E.firstName << endl; return output; } I will include a check for NULL pointer but I just want to get this working and will test it on a list that includes the data I am checking. Thanks to whoever can help and as usual, this is for a course so I don't expect or want the answer, but any tips as to what might be going wrong will help immensely!

  • python: list manipulation

    - by Jason S
    I have a list L of objects (for what it's worth this is in scons). I would like to create two lists L1 and L2 where L1 is L with an item I1 appended, and L2 is L with an item I2 appended. I would use append but that modifies the original list. How can I do this in Python? (sorry for the beginner question, I don't use the language much, just for scons)

    Hello, some one know how can I manipulate on some configuration over all projects in solution? For example, I create new configuration "Releas64" that means: "No debug, 64 bit, all files goes to c:\binaries", but I need to go over all 30 projects in our solution for to set those settings for every project. Is there some tool? Thank you for ahead.

  • Using a .delay() function before .css() manipulation in jQuery

    - by Fabian
    I have this: var $ul = $(this).children("ul"); $ul.animate({opacity: 0}, 1000); $ul.delay(1000).css("display", "none") It's for my dropdown menu, and I want it to fade off before it disappears using the display: none; CSS property. However it appears that the .delay() cannot be used on the .css(); it doesn't work, the $ul just disappears right away. I can't use $ul.animate({opacity: 0, display: "none"}, 1000); either.

  • Data manipulation without server side

    - by monczek
    Hi, I have to create a very simple webpage to show, filter and add data from not-yet-defined source (probably txt/xml/cvs). Records should be visible as a table, filtered using 3 criteria fields. There should be also possibility to add new records. My first thought was: XHTML + jQuery + csv2table + PicNet Table Filter. It does exactly what I want except adding rows - that is saving changes in source file (probably due to security risk). My question is - is there any possibility to do it without involving server side like asp.net, jee, php, sql? Source file is located on the server. Thanks for your ideas :-)

  • Window manipulation and inctences control

    - by touki
    In my application there are only 2 windows — win_a & win_b, on each of these windows there is button that call another window, e.g. click on btn1 of win_a will call win_b, click on btn2 of win_b will show win_a. Desired behaviour: 1. Only one instance of object is premitted at the same time, e.g. situation, where 2 instances of win_a running at the same time is not permitted. When you click on button that calls windows that already exist this action will only change a focus to needed window. If you call a window that previously had been created, but after this has been closed this action will create a new instance of this window. E.g. there are 2 running windows. you close one of them and after try to call this window back, so related button will create it. How to write it in WPF (XAML + C#). For the moment I wrote a version that can create a lot of instances of the same window (no number of instances control implemented), but I want to see only one instance of the same window, as we can see it in a lot of applications. Example of my code: Window win = new Window(); win.Show(); Thanks.

  • Iframe size manipulation

    - by portoalet
    Is there a way to make the Iframe request an external website as if it is a mobile device, so the content returned will have a small dimension etc? I am displaying external websites in iframes, using width and height attributes <iframe src="http://marketwatch.com" width="300px" height="300px" ></iframe> but because the browser is not a mobile browser, the content returned is tailored to normal browser, and I end up having scrollbars. If the content returned is that for a mobile device, then no more scrollbars etc.

  • Byte manipulation in PHP

    - by Michael Angstadt
    In PHP, if you have a variable with binary data, how do you get specific bytes from the data? For example, if I have some data that is 30 bytes long, how do I get the first 8 bytes? Right now, I'm treating it like a string, using the substr() function: $data = //... $first8Bytes = substr($data, 0, 8); Is it safe to use substr with binary data? Or are there other functions that I should be using? Thanks.

  • String manipulation appears to be inefficient

    - by user2964780
    I think my code is too inefficient. I'm guessing it has something to do with using strings, though I'm unsure. Here is the code: genome = FASTAdata[1] genomeLength = len(genome); # Hash table holding all the k-mers we will come across kmers = dict() # We go through all the possible k-mers by index for outer in range (0, genomeLength-1): for inner in range (outer+2, outer+22): substring = genome[outer:inner] if substring in kmers: # if we already have this substring on record, increase its value (count of num of appearances) by 1 kmers[substring] += 1 else: kmers[substring] = 1 # otherwise record that it's here once This is to search through all substrings of length at most 20. Now this code seems to take pretty forever and never terminate, so something has to be wrong here. Is using [:] on strings causing the huge overhead? And if so, what can I replace it with? And for clarity the file in question is nearly 200mb, so pretty big.

  • SCOM 2012 DNS Forwarder Availability Monitor

    - by Massimo
    Background: I have an environment with two different AD domains, each in its own forest, each with two Windows Server 2008 R2 domain controllers acting as DNS servers. There is no trust between the domains. Each DNS server manages the main DNS zone for its AD domain, and then some other zones, including the reverse lookup zone for its IP subnets; all zones are AD-integrated; all DNS servers which manages a zone are correctly listed as authoritative name servers for that zone. So, the situation is like this (using fake names and IP addresses): Domain A: DNS domain: a.dom IP subnet: 192.168.1.X DC/DNS Servers: serverA1.a.dom (192.168.1.1) and serverA2.a.dom (192.168.1.2) Authoritative zones: a.dom, 1.168.192.in-addr.arpa, somezone.local Domain B: DNS domain: b.dom IP subnet: 10.0.0.X DC/DNS Servers: serverB1.b.dom (10.0.0.1) and serverB2.b.dom (10.0.0.2) Authoritative zones: b.dom, 0.0.10.in-addr.arpa, someotherzone.local DNS servers in domain A have conditional forwarders defined for each zone managed by DNS servers in domain B, forwarding to both domain B's DNS servers; DNS servers in domain B have the opposite configuration. All forwarders are stored in Active Directory. All is working perfectly, and computers in each domain can resolve forward and reverse DNS queries for both domains, using their domain's DNS servers. The problem: I have SCOM 2012 deployed in domain A, with the SCOM agent installed on both DCs; the management packs for Active Directory and DNS Server are installed and up-to-date. I have a series of alerts like the following ones on both domain controllers; each alert is generated for each forwarded zone and for each forwarded server: Forwarder someotherzone.local (10.0.0.1) cannot resolve the host name 192.168.1.1,someotherzone.local for serverA1.a.dom Forwarder someotherzone.local (10.0.0.2) cannot resolve the host name 192.168.1.1,someotherzone.local for serverA1.a.dom Forwarder someotherzone.local (10.0.0.1) cannot resolve the host name 192.168.1.2,someotherzone.local for serverA2.a.dom Forwarder someotherzone.local (10.0.0.2) cannot resolve the host name 192.168.1.2,someotherzone.local for serverA2.a.dom Forwarder 0.0.10.in-addr.arpa (10.0.0.1) cannot resolve the host name 192.168.1.1,0.0.10.in-addr.arpa for serverA1.a.dom Forwarder 0.0.10.in-addr.arpa (10.0.0.2) cannot resolve the host name 192.168.1.1,0.0.10.in-addr.arpa for serverA1.a.dom Forwarder 0.0.10.in-addr.arpa (10.0.0.1) cannot resolve the host name 192.168.1.2,0.0.10.in-addr.arpa for serverA2.a.dom Forwarder 0.0.10.in-addr.arpa (10.0.0.2) cannot resolve the host name 192.168.1.2,0.0.10.in-addr.arpa for serverA2.a.dom The only exception is the main AD DNS zone managed by domain B's DNS servers (b.dom): for that conditional forwarder, no alert is generated and the forwarder availability monitor is green. Ok, what does this mean? What are those monitors trying to tell me? What are they checking? What's actually wrong? And why there is no error for the "b.dom" zone, which is configured in the exact same way as the other ones, both as a zone in domain B's DNS servers and as a forwarder in domain A's DNS servers?

    Hi, I am getting Out of Memory error: Memory Exception in thread "main" java.lang.OutOfMemoryError: Java heap space at org.apache.xerces.dom.CoreDocumentImpl.createElement(CoreDocumentImpl.java:564) I have a standalone Java program which fetches data from DB and create an XML file using DOM. I get the above error if the data fetched is huge, in my case it is 1,000,000 records. I have defined 2GB as heap size while calling the Java class from unix. I tried it with JAXB, but still do not any significant improvement. Any suggestions how to improve the code.

  • jQuery galleria plugin with dynamically loaded images

    - by panas
    I'm using the Galleria plugin with jQuery to create my image gallery. I'm trying to get load images dynamically from the user's selection into the DOM and have the gallery auto-update to display those new images but it's not working. Firebug shows the images are successfully loading into the DOM but Galleria displays no thumbnails. I need a way to reload Galleria to display the new images. /* ---- Gallery Code ---- */ if ($(this).find('div').attr('title') == 'photogallery' && $('.galleria_container').length == 0) { $('.gallery').galleria( { history : false, clickNext : true, onImage : function(image,caption,thumb) { if(! ($.browser.mozilla && navigator.appVersion.indexOf("Win")!=-1) ) { image.css('display','none').fadeIn(1000); } var _li = thumb.parents('li'); caption.css('display','none').fadeIn(1000); _li.siblings().children('img.selected').fadeTo(500,0.3); thumb.fadeTo('fast',1).addClass('selected'); image.attr('title','Next image >>'); }, onThumb : function(thumb) { var _li = thumb.parents('li'); var _fadeTo = _li.is('.active') ? '1' : '0.3'; thumb.css({display:'none',opacity:_fadeTo}).fadeIn(1500); thumb.hover ( function() { thumb.fadeTo('fast',1); }, function() { _li.not('.active').children('img').fadeTo('fast',0.3); } // don't fade out if the parent is active ) } }); } /* ---- Gallery Selector ---- */ $(document).ready(function() { var galleryImages = new Object(); <?php echo $myGal; ?> function setImages(type) { var image = ''; for (var i = 0; i < galleryImages[type].length; i++) { image += '<li><img src="' + galleryImages[type][i] + '"></li>'; } $('ul.gallery').html(image); } $('ul.menu-horiz li ul li').click(function() { setImages($(this).attr('rel')); }); }); The PHP code you see just creates an array of images. So to summarise my question: How can I reload Galleria once the new images have been loaded into the DOM?

  • TinyMCE editor dislikes being moved around

    - by zneak
    Hello guys, On a page I have, I need to move TinyMCE editors in the DOM tree once in a while. However, for some reason, the editor doesn't like it: it clears itself completely and becomes unusable. As far as I can see, this behavior is consistent between Safari 4 and Firefox 3.6, but not Internet Explorer 7/8. Here's an example. It truly is pissing me off to do something that works in Internet Explorer but not with more appreciable browsers. Is there something I missed in the docs about never trying to move an editor in the DOM tree? Is there some kind of workaround?

  • Firefox logs invalid URL?

    - by thanks for help
    I'm writing an extension for firefox. Using dom.location to keep track of visited search results pages, i'm getting this url http://www.google.com/search?hl=en&source=hp&q=hi&aq=f&aqi=&oq=&fp=642c18fb4411ca2e . If you click it, the google search results for "hi" should come up. You'll know that from the title bar - because the rest of the page won't load. This happens with any google search. Oddly enough, if you cut part of it off, so say, http://www.google.com/search?hl=en&source=hp&q=hi - it works! But Googling "hi" myself does give me a longish URL - http://www.google.com/#hl=en&source=hp&q=hi&aq=f&aqi=&oq=&fp=db658cc5049dc510 . I know for a fact that the first time that URL was visited, the page loaded, I did it myself. Can anyone make reason out of this? I just tried my experiment again, this time saving the original URL in the location bar. It turns out, dom.location.href is giving a different value. How is this happening? Original: http://www.google.com/#hl=en&source=hp&q=hi&aq=f&aqi=&oq=&fp=642c18fb4411ca2e dom.location.href http://www.google.com/search?hl=en&source=hp&q=hi&aq=f&aqi=&oq=&fp=642c18fb4411ca2e window.addEventListener("load", function() { myExtension.init(); }, false); var myExtension = { init: function() { var appcontent = document.getElementById("appcontent"); // browser if(appcontent) appcontent.addEventListener("DOMContentLoaded", myExtension.onPageLoad, true); var messagepane = document.getElementById("messagepane"); // mail if(messagepane) messagepane.addEventListener("load", function () { myExtension.onPageLoad(); }, true); }, onPageLoad: function(aEvent) { var doc = aEvent.originalTarget; // doc is document that triggered "onload" event // do something with the loaded page. // doc.location is a Location object (see below for a link). // You can use it to make your code executed on certain pages only. var url = doc.location.href; if (url.match(/(?:p|q)(?:=)([^%]*)/)) {alert("MATCH" + url);resultsPages.push(url);} else {alert(url); } } This snippet comes directly from Mozilla with the matching and alerts my own. I apologize for not posting the code earlier.

  • JQUERY-UI Draggables - Seralize is running before the Draggable is complete

    - by nobosh
    Hello, I'm using the JQUERY-UI draggable plugin. As a setting, when the Draggable is done, using the STOP setting I run a function to seralize a list of LIs to get their order in terms of their IDs. For example, if I have an UL, with a list of LIs with the following IDs: 1,2,3,4,5 If I then move 5, between 2&3, the seralize is returning: 1,2,5,3,4,5 Which makes me think that the JQUERY UI-Draggable STOP is running before the page is finished rendering, or the DOM isn't update? Any ideas on how I can fix this from happening. Is there something I can do in my Seralize funtion to say, wait till JQUERY animations are all done, or stop all that are going on to ensure the DOM is accurate? Thanks

  • Unique element ID, even if element doesn't have one

    - by Robert J. Walker
    I'm writing a GreaseMonkey script where I'm iterating through a bunch of elements. For each element, I need a string ID that I can use to reference that element later. The element itself doesn't have an id attribute, and I can't modify the original document to give it one (although I can make DOM changes in my script). I can't store the references in my script because when I need them, the GreaseMonkey script itself will have gone out of scope. Is there some way to get at an "internal" ID that the browser uses, for example? A Firefox-only solution is fine; a cross-browser solution that could be applied in other scenarios would be awesome. Edit: If the GreaseMonkey script is out of scope, how are you referencing the elements later? They GreaseMonkey script is adding events to DOM objects. I can't store the references in an array or some other similar mechanism because when the event fires, the array will be gone because the GreaseMonkey script will have gone out of scope. So the event needs some way to know about the element reference that the script had when the event was attached. And the element in question is not the one to which it is attached. Can't you just use a custom property on the element? Yes, but the problem is on the lookup. I'd have to resort to iterating through all the elements looking for the one that has that custom property set to the desired id. That would work, sure, but in large documents it could be very time consuming. I'm looking for something where the browser can do the lookup grunt work. Wait, can you or can you not modify the document? I can't modify the source document, but I can make DOM changes in the script. I'll clarify in the question. Can you not use closures? Closuses did turn out to work, although I initially thought they wouldn't. See my later post. It sounds like the answer to the question: "Is there some internal browser ID I could use?" is "No."
