  • Getting the text from a drop-down box

    - by Teifion
    This gets the value of whatever is selected in my dropdown menu. document.getElementById('newSkill').value I cannot however find out what property to go after for the text that's currently displayed by the drop down menu. I tried "text" then looked at W3Schools but that didn't have the answer, does anybody here know? For those not sure, here's the HTML for a drop down box. <select name="newSkill" id="newSkill" <option value="1"A skill</option <option value="2"Another skill</option <option value="3"Yet another skill</option </select Thanks

    - by yercaudARUN
    Hi All, I have a specific requirement of extracting text and images from a specific area in a pdf file.The area might be a selected or highlighted or from a given set of coordinates. When i went through, all the approaches are to extract images and text entirely from the PDF on not in a specified location. I tried with iTextSharp,Syncfussion,Apose but couldn figure out a better approach for this. If somebody could help me out in this it would be greatfull. Can you share your ideas and suggestion on how to implement this in .net. Regards, Arun.M

  • xmonad + urxvt issue: text disappears after resizing

    - by user1212010
    I'm using Arch Linux + xmonad + urxvt bundle and trying to resolve the conflict between xmonad and urxvt. Better to explain with shots: Firstly, open the terminal and get some full-length output. Secondly, create another window, which squeezes the first. And, finally, close it to find out that half of the output disappeared. Sometimes it behaves correctly, sometimes not. Tried to find out why, but failed. Many thx in advance!

  • paypal_adaptive gem in Rails: Dynamic Receiver "Population" (Chained Payments)

    - by Jmlevick
    Note: I didn't find a better title for this O.o Hello, Humm... Look, what I want to do is to have a Rails app where a visitor can click a button/link to make a "special" chained payment using Paypal; Currently I have a Users registration form that has one field for the user to enter his/her paypal account email, and as I saw here: http://marker.to/XGg9MR it is possible to specify the primary reciever and the secondary ones by adding such info in a controller action when using the paypal_adaptive gem in a rails app. The thing is, I don't want to hard code the secondary reciever as I need to specify a different secondary reciever from time to time, (being specific my primary reciever will always be the same, but depending on what button/link the visitor clicks, the secondary one is going to change) and I want that secondary reciever email to be the paypal e-mail account from one of the registered users when the visitor clicks on their specific button/link... My question is: Is it possible to create such enviroment functionality in my app using the current implementation of the paypal_adaptive gem? Could someone point me in the right direction on how to accomplish such thing? I'm still learning rails and also I'm really new in the paypal handling universe with this framework! XD P.S. Thanks! :)

  • Dynamic binding in C++

    - by chmike
    I'm implementing a CORBA like server. Each class has remotely callable methods and a dispatch method with two possible input, a string identifying the method or an integer which would be the index of the method in a table. A mapping of the string to the corresponding integer would be implemented by a map. The caller would send the string on the first call and get back the integer with the response so that it simply has to send the integer on subsequent calls. It is just a small optimization. The integer may be assigned dynamically on demand by the server object. The server class may be derived from another class with overridden virtual methods. What could be a simple and general way to define the method binding and the dispatch method ?

  • jQuery javascript dynamic menus with mbMenu plugin

    - by lafoaug
    Im using the MbMenu jQuery plugin. http://plugins.jquery.com/project/mbMenu http://pupunzi.open-lab.com/2009/01/18/mbmenu/ I am probably being ridiculously stupid but I wish to have multiple menus on the same page, but not load them from external files (the html structure of the menu already exists on the page). To me the only place you define what menu is linked to the element you call buildMenu on is the 'template' construction which is a external file. Thanks.

  • Drupal CCK Text field not saving.

    - by Mark Milbourne
    Hey Guys, I've been trying to write a CCK Field based on the Text field. But if I create a standard CCK Text field with only 1 value. Then edit a content item for this type, the values are never persisted. When I go back in and edit the same node, the value isn't there. I checked the database and its not in the table for the CCK node. If I use more than one value it works fine. I'm upto date on CCK (6.x-2.6) and CTools (6.x-1.5). Has anyone seen this? and a possible solution?

  • TextBox loses text when InvokeRequired == false

    - by Tom
    This is modified code I found on this site. When appending text to a TextBox and InvoveRequired is false the text will display in the box but the next time the function is called and InvokeRequired is true the text string placed by the first call is lost (""). Multiple calls when InvokeRequired is true work as expected. comBox is a type TextBox with multline = true. Any help would be appreciated. public void LogComText(string comText, bool newline) { if (comBox.InvokeRequired) { comBox.BeginInvoke(new Action(delegate { LogComText(comText, newline); })); return; } comBox.AppendText(comText); if (newline) comBox.AppendText(Environment.NewLine); }

  • How do I write a Java text file viewer for big log files

    - by Hannes de Jager
    I am working on a software product with an integrated log file viewer. Problem is, its slow and unstable for really large files because it reads the whole file into memory when you view a log file. I'm wanting to write a new log file viewer that addresses this problem. What are the best practices for writing viewers for large text files? How does editors like notepad++ and VIM acomplish this? I was thinking of using a buffered Bi-directional text stream reader together with Java's TableModel. Am I thinking along the right lines and are such stream implementations available for Java?

  • Dynamic allocating of const member structures

    - by Willy
    I've got class which is using plain-only-data struct with const variables and I'm not sure, if I'm allocating these structures in a proper way. It looks more or less like: #include <cstdlib> #include <iostream> using std::cout; using std::endl; struct some_const_struct { const int arg1; const int arg2; }; class which_is_using_above_struct { public: some_const_struct* m_member; const some_const_struct* const m_const_member; public: const some_const_struct& get_member() const { return *m_member; } const some_const_struct& get_const_member() const { return *m_const_member; } void set_member(const int a, const int b) { if(m_member != NULL) { delete m_member; m_member = NULL; } m_member = new some_const_struct((some_const_struct){a, b}); } explicit which_is_using_above_struct(const int a, const int b) : m_const_member(new some_const_struct((const some_const_struct){a, b})) { m_member = NULL; } ~which_is_using_above_struct() { if(m_member != NULL) { delete m_member; } if(m_const_member != NULL) { delete m_const_member; } } }; int main() { which_is_using_above_struct c(1, 2); c.set_member(3, 4); cout << "m_member.arg1 = " << c.get_member().arg1 << endl; cout << "m_member.arg2 = " << c.get_member().arg2 << endl; cout << "m_const_member.arg1 = " << c.get_const_member().arg1 << endl; cout << "m_const_member.arg2 = " << c.get_const_member().arg2 << endl; return 0; } I'm just not quite sure if the statement: m_member = new some_const_struct((some_const_struct){a, b}); doesn't produce unnessesary use of some_const_struct's copy constructor, ergo allocating that struct twice. What do you think? And is it reasonable to make that struct's members const? (they're not supposed to change in their lifetime at all)

  • HTML dynamic tags insert looks different compared to static layout

    - by Andrew Florko
    I program HTML interface with jquery. There is editable list of publications on the page and user can click any publication to edit details. Popup window appears with data and there is list of authors embedded into details form. There are edit/delete buttons against every of them + "add new author" button. User manipulates authors without page reload. When I insert a new author there are new edit/delete buttons created dynamically & embedded into page. I insert tags like this: <td class="author-actions"> <img onclick='edit(id)' .../> <img onclick='delete(id)' .../> </td> Just the same html-layout that is sent from web-server when popup window appears. But somehow it looks different. There is extraspace between images though firebug demonstrates the same css attributes applied. If I select with mouse inserted layout with IE, somehow it can reorder and become the same-looklike as the those, send by web-server. What can it be?

  • C++ Dynamic Allocation Mismatch: Is this problematic?

    - by acanaday
    I have been assigned to work on some legacy C++ code in MFC. One of the things I am finding all over the place are allocations like the following: struct Point { float x,y,z; }; ... void someFunc( void ) { int numPoints = ...; Point* pArray = (Point*)new BYTE[ numPoints * sizeof(Point) ]; ... //do some stuff with points ... delete [] pArray; } I realize that this code is atrociously wrong on so many levels (C-style cast, using new like malloc, confusing, etc). I also realize that if Point had defined a constructor it would not be called and weird things would happen at delete [] if a destructor had been defined. Question: I am in the process of fixing these occurrences wherever they appear as a matter of course. However, I have never seen anything like this before and it has got me wondering. Does this code have the potential to cause memory leaks/corruption as it stands currently (no constructor/destructor, but with pointer type mismatch) or is it safe as long as the array just contains structs/primitive types?

  • C++ dynamic array causes segmentation fault at assigment

    I am doing a application witch uses sockets so I am holding in an array the sockets handles.I have the following code: while(0 == 0){ int * tx = (int*)(malloc((nr_con + 2) * sizeof(int))); if (conexiuni != NULL) { syslog(LOG_NOTICE,"Ajung la eliberare %d",nr_con); memcpy(&tx[0],&conexiuni[0],(sizeof(int) * (nr_con))); syslog(LOG_NOTICE,"Ajung la eliberare %d",nr_con); free(conexiuni); } conexiuni = tx; syslog(LOG_NOTICE,"Ajung la mama %d",nr_con); //The line bellow causes a segfault at second connection if ((conexiuni[nr_con] = accept(hsock,(sockaddr*)(&sadr),&addr_size)) != -1) { nr_con++; syslog(LOG_NOTICE,"Primesc de la %s",inet_ntoa(sadr.sin_addr)); syslog(LOG_NOTICE,"kkt %d",conexiuni[nr_con - 1]); int * sz = (int*)malloc(sizeof(int)); *sz = conexiuni[nr_con - 1]; syslog(LOG_NOTICE,"after %d",*sz); pthread_create(&tidi,0,&ConexiuniHandler, sz); } } When I connect the second time when I assign the array the program crashes. What am I doing wrong? I tried the same code on Windows and it works well but on Linux it crashes.

  • Automatic highlighting of text in thunderbird

    - by m000
    In days with large email influx, some emails tend to slip out of my attention. Usually these are email where I am not the primary recipient, but I am referenced at some point as having to perform some action. This point may occur after several responses to a thread. E.g.: Hello B, Hello A, Dear all, Could someone give me feedback on document X? Thanks, A. Please find my remarks below: ... Best, B. Thank you for the feedback. I have incorporated it in the document. C, can you make a final proof-reading pass and post it online? Thanks, A. Is there a way in thunderbird to highlight the sentence/paragraph where my name ("C" in this example) or some other configurable keyword occurs, so that I can easily check if I have to take action? Note that I am looking for a way to identify the part of the message that directly concerns me and not which messages concern me. So, filters/tags won't really help.

  • Smarty dynamic error list

    - by Brainscrewer
    Im new to Smarty in combination with PHP and I really like it. Unfortunatly im running into a problem while validating fields after a $_POST has been done. I've made an array called $errors and use that to save error messages in, for example: $errors[] .= "Wrong email";. My problem is in sending the $errors array over to the template so I can use it to display the error messages. My question: How do you 'transfer' the $errors variable over to the template file so you can use it there with, for example {foreach}. I was planning on doing something like {if $hasErrors} {foreach from=errors item=error} <li>{$error}</li> {/foreach} {/if} Thanks in advance

  • C++ Dynamic object construction

    - by Rajesh Subramanian
    I have a base class, class Msg { ParseMsg() { ParseMsgData(); ParseTrailer(); } virtual void ParseMsgData() = 0; ParseTrailer(); }; and derived classes, class InitiateMsg { void ParseMsgData() { ... } }; class ReadOperationMsg { void ParseMsgData() { ... } }; class WriteOperationMsg { void ParseMsgData() { ... } }; and the scenario is below, void UsageFunction(string data) { Msg* msg = ParseHeader(data); ParseMsg } Msg* ParseHeader(string data) { Msg *msg = NULL; .... switch() { case 1: msg = new InitiateMsg(); break; case 2: msg = new ReadOperationMsg{(); break; case 3: msg = new WriteOperationMsg{(); break; .... } return msg; } based on the data ParseHeader method will decide which object has to be created, So I have implemented ParseHeader function outside the class where I am using. How can I make the ParseHeader function inside the Msg class and then use it? In C# the same is achieved by defining ParseHeader method as static with in class and use it from outside,

  • Need to dynamically-generate a "sticky note" text

    - by gravyface
    Working on a website that has an image of a sticky note which will change text somewhat frequently (every month or so) as new "todo" items are created on it. Font I'm currently using is not Web Safe and the text is slightly angled to match the skew of the sticky note as well. Now I'm a pragmatist, and in situations like this I would normally secede defeat and opt for something more CSS/HTML practical. But no more! I'm falling a bit behind on what's going on with HTML5, CSS3, PNG graphics, Flash (ugh), and/or any other rich visuals. I'm decent with PHP/CSS/JS (jquery), have dabbled in Flash/actionscript too. My question is: what tools/method should I be looking at here?

  • dynamic inheritance without touching classes

    - by Jasper
    I feel like the answer to this question is really simple, but I really am having trouble finding it. So here goes: Suppose you have the following classes: class Base; class Child : public Base; class Displayer { public: Displayer(Base* element); Displayer(Child* element); } Additionally, I have a Base* object which might point to either an instance of the class Base or an instance of the class Child. Now I want to create a Displayer based on the element pointed to by object, however, I want to pick the right version of the constructor. As I currently have it, this would accomplish just that (I am being a bit fuzzy with my C++ here, but I think this the clearest way) object->createDisplayer(); virtual void Base::createDisplayer() { new Displayer(this); } virtual void Child::createDisplayer() { new Displayer(this); } This works, however, there is a problem with this: Base and Child are part of the application system, while Displayer is part of the GUI system. I want to build the GUI system independently of the Application system, so that it is easy to replace the GUI. This means that Base and Child should not know about Displayer. However, I do not know how I can achieve this without letting the Application classes know about the GUI. Am I missing something very obvious or am I trying something that is not possible?
