  • php class basic question

    - by Ross
    hi <?php class myClass { var $input; var $output; function myClass($input) { $output = 'You entered: ' . $input; return $output; } } $test = new myClass; echo $test->myClass(123); ?> this works, but returns this warning: Warning: Missing argument 1 for myClass::myClass() I read in to this, and seems that the constructor is expecting a value, so by adding: function myClass($input='') the warning is removed, but this seems so unnecessary? could someone enlighten me as to why it's required to define a value to prevent that warning? thanks for any pointers

  • Ranged integers in .NET (or C#)

    - by Mal Ross
    Am I being blind, or does the .NET framework not provide any kind of ranged integer class? That is, a type that would prevent you setting a value outside some given bounds that are not the full range of the basic data type. For example, an integer type that would restrict its values to between 1 and 100. Showing my age here, but back in '93, I remember using that sort of thing in Modula-2 (eeek!), but I've not seen explicit framework / language support for it since. Am I just missing something, or is it a case of "it's so simple to make your own that the framework doesn't bother"? Cheers.

  • What tools do you use to share knowledge amongst developers in your company?

    - by Chris Ross
    I'm looking for some good tools that help to share tips, best practices, company standards, etc. amongs developers in my company. Two tools I'm currently considering are a wiki (screwturn wiki) or Sharepoint 2010. I'm wondering if there is something better suited to the task, or any input anyone has on this subject. I'd prefer something that's windows based (i.e. runs on IIS, can authenticate users against Active Directory etc) but I am open to anything.

  • IEnumerator: Is it normal to have an empty Dispose method?

    - by C. Ross
    I'm writing an IEnumerator<T> class to iterate over a COM collection I'm wrappering. I've noticed that IEnumerator<T> extends IDisposable, so I'm required to implement the Dispose method. However, I can't think of anything I would put there, as I only have a reference to the collection (which I wouldn't want being disposed at the end of a foreach), and an int for the index. Is it normal to leave the Dispose method empty?

  • Property trigger in XAML for IsMouseOver fails to set Border.Background

    - by Mal Ross
    I'm currently trying to create a ControlTemplate for the Button class in WPF, replacing the usual visual tree with something that makes the button look similar to the little (X) close icon on Google Chrome's tabs. I decided to use a Path object in XAML to achieve the effect. Using a property trigger, the control responds to a change in the IsMouseOver property by setting the icon's red background. Here's the XAML from a test app: <Window x:Class="Widgets.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Window.Resources> <Style x:Key="borderStyle" TargetType="Border"> <Style.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter Property="Background"> <Setter.Value> <SolidColorBrush Color="#CC0000"/> </Setter.Value> </Setter> </Trigger> </Style.Triggers> </Style> <ControlTemplate x:Key="closeButtonTemplate" TargetType="Button"> <Border Width="12" Height="12" CornerRadius="6" BorderBrush="#AAAAAA" Background="Transparent" Style="{StaticResource borderStyle}" ToolTip="Close"> <Viewbox Margin="2.75"> <Path Data="M 0,0 L 10,10 M 0,10 L 10,0" Stroke="{Binding BorderBrush, RelativeSource={RelativeSource FindAncestor, AncestorType=Border, AncestorLevel=1}}" StrokeThickness="1.8"/> </Viewbox> </Border> </ControlTemplate> </Window.Resources> <Grid Background="White"> <Button Template="{StaticResource closeButtonTemplate}"/> </Grid> </Window> Note that the circular background is always there - it's just transparent when the mouse isn't over it. The problem with this is that the trigger just isn't working. Nothing changes in the button's appearance. However, if I remove the Background="Transparent" value from the Border object in the ControlTemplate, the trigger does work (albeit only when over the 'X'). I really can't explain this. Setters for any other properties placed in the borderStyle resource work fine, but the Background setter fails as soon as the default background is specified in the ControlTemplate. Any ideas why it's happening and how I can fix it? I know I could easily replace this code with, for example, a .PNG-based image, but I want to understand why the current implementation isn't working. Thanks! :)

  • Create a string with n characters.

    - by C. Ross
    Is there a way in java to create a string with a specified number of a specified character? In my case I would need to create a string with 10 spaces. My current code is: StringBuffer outputBuffer = new StringBuffer(length); for (int i = 0; i < length; i++){ outputBuffer.append(" "); } return outputBuffer.toString(); Is there a better way to accomplish the same thing. In particular I'd like something that is fast (in terms of execution).

  • Marking "example usage" in code documentation

    - by Ross
    What the best practice of placing example usage in code documentation? Is there a standardised way? With an @usage or @notes? For example: /** * My Function * @param object id anObject * @usage a code example here... */ function foo(id) { } or /** * My Function * @param object id anObject * @notes a code example here, maybe? */ function foo(id) { } I know this question should dependent on the documentation generator, but any heads up appreciated... I'm trying to get into the habit of using proper style. When time allow I'll get more into the generators. (I've experimented with Doxygen.) I often use AS3, JS, Obj-C, C++. Thanks

  • Is there a faster way to access a property member of a class using reflection?

    - by Ross Goddard
    I am currently using the following code to access the property of an object using reflection: Dim propInfo As Reflection.PropertyInfo = myType.GetProperty(propName) Dim objValue As Object = propInfo.GetValue(myObject, Nothing) I am having some issues with the speed since this type of code is being called many times and is causing some slowdown. I have been looking into using Refelction.Emit or dynamic methods, but I am not sure exactly how to make use of them. Background Information: I am creating a list of a subset of the properties of the object, associating then with some meta information (such as if they can be loaded from the database or xml, if they are editable, can the user see them). This is for later consumption so we can write code such as : foreach prop as BaseWrapper in graphNode.NodeProperties prop.LoadFromDataRow(dr) next The application makes heavy use of having access to this list. The problem is that on the initial load of a project, a larger number of objects are being created that make use of this, so for each object created it is looping through this code a number of times. I initially tried adding each property to the list manually, but this ran into problems with not everything being initialized at the correct time and some other issues. If there is no other good way, then I may have to rethink some of the design and see what else can be done to improve the performance.

  • iPhone: Going from transformed layers to jpeg

    - by Devin Ross
    I have a bunch of images that are transformed (using touch gestures). I want to take the transformations the user does to the images and create a jpeg from it. (ie. if a user rotates a photo to the right, I want to get a jpeg of the photo rotate to the right just as the looks on screen). This takes into account that the photo could be bigger than whats displayed on screen too (no screenshots). I'm trying to use CGContext (CGContextRotateCTM specifically) but its not been too successful. Thanks for the help.

  • Unable to `submit()` an html form after intercepting the submit with javascript.

    - by Ross Rogers
    I'm trying to intercept the submission of a form in order to change the value of my keywords label. I have the following code: <HTML> <FORM name="searchForm" method="get" action="tmp.html" > <input type="label" name="keywords" /> <input type="button" name="submit" value="submit" onclick="formIntercept();"/> </FORM> <SCRIPT language="JavaScript"> document.searchForm.keywords.focus(); function formIntercept( ) { var f = document.forms['searchForm']; f.keywords.value = 'boo'; f.submit(); }; </SCRIPT> </HTML> When I run this in chrome and click the submit button the keywords label changes to boo, but the javascript console says: Uncaught TypeError: Property 'submit' of object <#an HtmlFormElement> is not a function. How can I submit the form with the manipulated keywords?

  • Tool for sql refactoring?

    - by C. Ross
    Is there a refactoring tool available for SQL (TSQL in particular). Is there any tool that can do automatic simplification of SQL? I have a set of views where only the top two are used, and I'd like to refactor this into only two views, hence 10+ queries into two queries.

  • New records added to DataGridView aren't displayed

    - by Ross
    I have a custom Order class, groups of which are stored in List<Order> and a DataGridView. I think the problem is in my implementation so here's how I'm using it: In the form enclosing DataGridView (as OrdersDataGrid): public partial class MainForm : Form { public static List<Order> Orders; public MainForm() { // code to populate Orders with values, otherwise sets Orders to new List<Order>(); OrdersDataGrid.DataSource = Orders; } Then in another form that adds an Order: // Save event public void Save(object sender, EventArgs e) { Order order = BuildOrder(); // method that constructs an order object from form data MainForm.Orders.Add(order); } From what I can tell from the console this is added successfully. I thought the DataGrid would be updated automatically after this since Orders has changed - is there something I'm missing? The DataGrid accepts the class since it generates columns from the members.

  • Pushing to an array not working as expected

    - by Ross Attrill
    When I execute the code below, my array 'tasks' ends up with the same last row from the dbi call repeated for each row in the database. require 'dbi' require 'PP' dbh = DBI.connect('DBI:ODBC:Driver={SQL Server Native Client 10.0};Server=localhost,1433;Database=db;Uid=db;Pwd=mypass', 'db', 'mypass') sth = dbh.prepare('select * from TASK') sth.execute tasks = Array.new while row=sth.fetch do p row tasks.push(row) end pp(tasks) sth.finish So if I have two rows in my TASK table, then instead of getting this in the tasks array: [[1, "Task 1"], [2, "Task 2"]] I get this [[2, "Task 2"], [2, "Task 2"]] What am I doing wrong?

  • many-to-many relationship in CI (not using ORM)

    - by Ross
    I'm implementing a categories system in my CI app and trying to work out the best way of working with many to many relationships. I'm not using an ORM at this stage, but could use say Doctrine if necessary. Each entry may have multiple categories. I have three tables (simplified) Entries: entryID, entryName Categories: categoryID, categoryname Entry_Category: entryID, categoryID my CI code returns a record set like this: entryID, entryName, categoryID, categoryName but, as expected with Many-to-Many relationships, each "entry" is repeated for each "category". What would the best way to "group" the categories so that when I output the results, I am left with something like: Entry Name Appears in Category: Foo, Bar rather than: Entry Name Appears in Category: Foo Entry Name Appears in Category: Bar I believe the option is to track if the post ID matches a previous entry, and if so, store the respective category, and output it as one, rather than several, but am unsure of how to do this in CI. thanks for any pointers (I appreciate this is may be a vague/complex question without a better knowledge of the system).
