  • c# memory allocation and deallocation patterns

    - by Neal
    Since C# uses Garbage Collection. When is it necessary to use .Dispose to free the memory? I realize there are a few situations so I'll try to list the ones I can think of. If I close a Form that contains GUI type object, are those objects dereferenced and therefore will be collected? If I create a local object using new should I .Dispose of it before the method exits or just let the GC take care of it? What is good practice in this case? Are there any times in which forcing a GC is understandable? Are events collected by the GC when it's object is collected?

  • Javascript Dropdownbox

    - by edgar
    I have a dropdownbox (percent), a input box(price) and a input box (total) When you select a percent from the dropdown, it multiplies the value of the selected dropdown times the price value and input the result in the total input box. This works well with one input box, but what I am trying to do is to use asp and when you select a percent from the drop down box, it will calcualate the rest of the total fields. Here is the code that I have so far <%@LANGUAGE="VBSCRIPT" CODEPAGE="1252"% <% Dim Recordset1 Dim Recordset1_numRows Set Recordset1 = Server.CreateObject("ADODB.Recordset") Recordset1.ActiveConnection = MM_pricdsn_STRING Recordset1.Source = "SELECT * FROM AMFLIB.MBCWCPP where cwfvnb = 1090101 and cwaitx between '0025' and '0025AT'" Recordset1.CursorType = 0 Recordset1.CursorLocation = 2 Recordset1.LockType = 1 Recordset1.Open() Recordset1_numRows = 0 %> <% Dim Repeat1__numRows Dim Repeat1__index Repeat1__numRows = -1 Repeat1__index = 0 Recordset1_numRows = Recordset1_numRows + Repeat1__numRows %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> Javascript Untitled Document <script type="text/javascript"> function startCalc4(){ interval = setInterval("calc4()",1); } function calc4(){ one = document.form1.prcbook.value; two = document.form1.percent.value; document.form1.total.value = (one * 1) * (two * 1); } function stopCalc4(){ clearInterval(interval); } </script> <style type="text/css"> <!-- #Layer1 { position:absolute; left:26px; top:49px; width:150px; height:24px; z-index:1; } #Layer2 { position:absolute; left:36px; top:22px; width:166px; height:22px; z-index:2; } #Layer3 { position:absolute; left:19px; top:24px; width:174px; height:21px; z-index:3; } --> </style> <script type="text/javascript"> function showhideText(box,id) { var elm = document.getElementById(id) elm.style.display = box.checked?

  • ASP. Net MVC and RegisterClientScriptBlock alternative

    - by Noel
    I currently have a web form aspx page that calls RegisterClientScriptBlock. This sends down message text that I use for client side validation e.g. <script type="text/javascript"> //<![CDATA[ var c_errorMessages = { RequiredField : "* Mandatory field" }; //]]> </script> The values are generated on the server side based on culture and resource files. I believe you cannot use RegisterClientScriptBlock with MVC. Any ideas on how I can achieve this with MVC?

  • multiple records using the select_tag

    - by JZ
    I'm attempting to display multiple records, with each record displaying its own selection box. I would like to submit this form and pass a hash, having the Add.id function as the key of the hash, and the selection box option pass as the information in the hash.

  • Implicitly invoking parent class initializer

    - by Matt Joiner
    class A(object): def __init__(self, a, b, c): #super(A, self).__init__() super(self.__class__, self).__init__() class B(A): def __init__(self, b, c): print super(B, self) print super(self.__class__, self) #super(B, self).__init__(1, b, c) super(self.__class__, self).__init__(1, b, c) class C(B): def __init__(self, c): #super(C, self).__init__(2, c) super(self.__class__, self).__init__(2, c) C(3) In the above code, the commented out __init__ calls appear to the be the commonly accepted "smart" way to do super class initialization. However in the event that the class hierarchy is likely to change, I have been using the uncommented form, until recently. It appears that in the call to the super constructor for B in the above hierarchy, that B.__init__ is called again, self.__class__ is actually C, not B as I had always assumed. Is there some way in Python-2.x that I can overcome this, and maintain proper MRO when calling super constructors without actually naming the current class?

  • Opposite of nl2br? Is it str_replace?

    - by Julian H. Lam
    So the function nl2br is handy. Except in my web app, I want to do the opposite, interpret line breaks as new lines, since they will be echoed into a pre-filled form. str_replace can take <br /> and replace it with whatever I want, but if I put in \n, it echoes literally a backslash and an n. It only works if I put a literal line break in the middle of my script, and break the indentation (so there are no trailing space). See: <?=str_replace('<br />',' ',$foo)?> Am I missing escape characters? I think I tried every combination...

  • fastercsv parsing to int or other into ActiveRecord

    - by Schroedinger
    I'm currently importing a CSV into an activerecord element but can't choose to parse the elements as say ints or decimals on a case by case basis using fastercsv. I can either choose to parse everything as an int or the other, or all as strings. I need to parse some columns as ints, some as decimals and some as strings. Otherwise, is there a way after I've parsed everything as strings to convert and update individual elements in the activerecord to the new form? Say parse values in as strings then convert certain values to ints, others to decs, etc?

  • How to convert string HH:MM to Joda Duration?

    - by Lucas T
    I have a field in a form to state the time duration of an event. Say, the event is to last 15 mins. So the field will have the following value: 00:15 If it is to last 1 hour: 01:00, etc. How can I create a Joda Duration object with the string "HH:MM"? Looking at Joda Time home page, it mentions that it is possible to create a Duration object from specified object using ConverterManager and DurationConverter respectively. My question is, how can I implement the above interfaces so that I can create a Duration object by passing the a "4:30" parameter? Thanks in advance, Lucas

  • load images dynamically on scroll in blackberry

    - by Maneesh
    How to display images in the form of pages where only one page is displayed at a time on blackberry screen. On scrolling down subsequent images will load at run time. So that loading of images do not consume time at startup. Edit: I am using loadimage function which loads images from blackberry device memory which loads images from specified path and resizing them.As number of images increases, it increases the startup time during opening of window.There is an in-built application(Media) in blackberry phone, where images load without taking any extra time. My idea is to display particular number of images which fit to the blackberry screen. As user scroll down to bottom of screen, application will then load and display more images. So my question is how to detect when user reached to bottom of blackberry screen and display one more row images.

  • Graph coloring Algorithm

    - by Amitd
    From wiki In its simplest form, it is a way of coloring the vertices of a graph such that no two adjacent vertices share the same color; this is called a vertex coloring. Similarly, an edge coloring assigns a color to each edge so that no two adjacent edges share the same color, and a face coloring of a planar graph assigns a color to each face or region so that no two faces that share a boundary have the same color. Given 'n' colors and m vertices, how easily can a graph coloring algorithm be implemented? Lan

  • CodeIgniter Unable to Access Error Message Error

    - by 01010011
    Hi, I've created this registration form for registering new users to a website using CodeIgniter. My problem is, whenever I enter a username that already exists in my database, instead of giving me my error message which explains this to the user, it instead gives me this error message: Unable to access an error message corresponding to your field name Here are snippets of the code from my controller. Any assistance will be appreciated: function register() $this->load->library('form_validation'); $this->form_validation->set_rules('username', 'Username','trim|required|alpha_numeric|min_length[6]|xss_clean|strtolower|callback_username_not_exists); ... } function username_not_exists($username) { $this->form_validation->set_message('username','That %s already exists.'); if($this->User_model->check_exists_username($username)) { return false; } else { return true; }

  • ASP.NET MVC SSL POST Error

    - by RyanFetz
    I have a Logon page in a MVC (1.0) application that I am securing with SSL, I have an attribute that inspects the request for the page and redirects to a https uri when it is requested with http. This all works, however when I post the form content i get the following error: The parameters dictionary contains a null entry for parameter 'rememberMe' of non-nullable type 'System.Boolean' for method 'System.Web.Mvc.ActionResult LogOn(System.String, System.String, Boolean, System.String)' in 'DAC.US.Web.Portal.Controllers.AccountController'. To make a parameter optional its type should be either a reference type or a Nullable type. Parameter name: parameters here is the controller code... // // GET: /Account/LogOn [RequiresSSL] public ActionResult LogOn(string ReturnUrl) { if (TempData["Message"] != null) ViewData["Message"] = TempData["Message"]; TempData["Message"] = null; ViewData["ReturnUrl"] = ReturnUrl ?? "/Home"; return View(); } Again, the RequireSSL Attribute works, but the POST from that SSL uri does not. What is not working?

  • Header file-name as argument

    - by Alphaneo
    Objective: I have a list of header files (about 50 of them), And each header-file has few arrays with constant elements. I need to write a program to count the elements of the array. And create some other form of output (which will be used by the hardware group). My solution: I included all the 50 odd files and wrote an application. And then I dumped all the elements of the array into the specified format. My environment: Visual Studio V6, Windows XP My problem: Each time there is a new set of Header files, I am now changing the VC++ project settings to point to the new set of header files, and then rebuild. My question: A bit in-sane though, Is there any way to mention the header from some command line arguments or something? I just want to avoid re-compiling the source every time...

  • dbpedia auto-suggest labels

    - by Sid
    Wikipedia has a auto-suggest feature on its search field. If you for instance type in "mars" it lists a few items including Mars, Marseille, Marsh. I am looking to implement something similar working off the latest DBpedia export (wikipedia in database form). If I do a search for all labels in the labels_en.nt file that DBpedia offer that begin with "mars" then, even if I remove ones that redirect on to others that are listed, I end up with a huge list. In trying to understand how wikipedia does this I noticed that I'm actually querying this URL which returns a JSON string. Now my problem is that I don't know how wikipedia narrows the list down. Perhaps it does so based on page popularity. The higher views/edits a page has the higher it goes in this suggestion box. If so, does DBpedia export this information?

  • WPF, animate over container boundaries

    - by ImIan
    Hi, I'm learning WPF and have a specific goal. Imagine you have a grid (3 rows by 3 columns), and a control, say a simple blue rectangle fills the middle cell. When I click on the cell I want the square to rotate smoothly through 180 degrees. The specific issue I have at the moment is; as the rectangle rotates, it won't change its dimensions, so it will extend beyond the boundary of the cell. I don't want it to clip, i want it to appear on top, partially obscuring surrounding cells. The second part of this is, if there is one cell that fills the entire window, and I click on the blue rectangle in that cell, can I make the rectangle rotate and extend beyond the sides of the form? If that doesn't make sense, please ask. I'm finding it hard to google because I don't know the exact terms I should be using. Thank you

  • posting php variable that contains apostrophe

    - by user1658170
    I am having trouble posting a php variable to another page. The variable is retrieved from a dropdown selected by the user and if it contains an apostrophe, I only get the part prior to the apostrophe posted. I.E. If I want to post "Cooper's Hawk" I am only receiving "Cooper". How do I escape this properly so that I can post the entire string? This is what I have: echo '<form method="POST" action="advanced_search2.php">'; $dropdown_english_name = "<select class = 'dropdown' name='english_name'> <option>ALL</option>"; $posted_value = ($_POST['english_name']); echo;$posted_value;die; So, to clarify from the above code, the posted string is "cooper's hawk" but the echoed output is "Cooper". Thanks in advance for any tips.
