  • IBM Informix using spatial datablade

    - by changed
    I need to use IBM Informix for my project where I have point coordinates and I need to find which points are present in query rectangular region.

But problem is how to do a SELECT statement, something which list all the points in a particular rectangular region.

    I get an error that says Parse error: syntax error, unexpected T_PRIVATE in E:\PortableApps\xampp\htdocs\SN\AC\ACclass.php on line 6 while trying to run my script.

Here's the code for that part. <?php class ac { public function authentication() { private $plain_username = $_POST['username']; private $md5_password = md5($_POST['password']); $ac = new ac();

  • dark VS2008, Windows 7 theme, configuration

    - by Aurelius
    So there's plenty of vs.settings files for nice dark syntax highlighting in VS2008, but I find them basically unusable since they're surrounded by an otherwise white visual studio application and general windows environment. I'd like an adequate dark windows 7 theme I can use while coding in VS. All of the 3rd party Win7 themes (that utilize the patched system files) I've come across have had fairly major problems and were unusable for one reason or another. Does anyone out there have a dark theme + VS combination they're actually happy with?

  • Dynamically add a field to an object in matlab

    - by Marc
    Say I have a MATLAB object defined in a class file classdef foo properties bar end end And I create a foo object myfoo = foo(); Now I want to add another field to foo dynamically. What I want is foo.newfield = 42; but this will throw an error. I know there is a way to dynamically add a field/property to a MATLAB object but I can't remember it or find it easily in the help. Anyone know the syntax?

    I'm trying to configure the cygwin to work with TWiki, I have to input this in the Cygwin bash shell: mount -b -s c:/... but it doesn't recognize the "-s", I already fixed the problem with -b, it changed the syntax and now is "mount -o binary" for the "mount -b"part. But now it says unknown option with the "-s" anyone?? help?? or what does the -s mean, so I can look it up :S

  • Giving event control back to xaml/callee to access check/uncheck

    - by dovholuk
    Hi All, I've scoured the Internet but my search-foo must not work if it's out there cause I just can't find the proper search terms to get me the answer I am looking for. So I turn to the experts here as a last resort to point me in the right direction. What I'm trying to do is create a composite control of a text box and a list box but I want to allow the control consumer to decide what to do when say the checkbox is checked/unchecked and I just can't figure it out... Maybe i'm going about it all wrong. What I've done thus far is to: create a custom control that extends ListBox expose a custom DP named "Text" (for the Text box but it's not the important part) craft the generic.xaml so that the list items have a default ItemTemplate/DataTemplate inside the DataTemplate I'm trying to set the "Checked" or "Unchecked" events expose 'wrapper' events as DPs in the custom control that would get 'set' via the template when instatiated As soon as I try something like the following (inside generic.xaml): <DataTemplate> <...> <CheckBox Checked="{TemplateBinding MyCheckedDP}"/> <...> </DataTemplate> I get runtime exceptions, the designer - vs2010 - pukes out a LONG list of errors that are all very similar and nothing I do can make it work. I went so far as to try using the VisualTreeHelper but no magic combination I could find would work nor would it allow me to traverse the tree because when the OnApplyTemplate method fires the listbox items don't exist yet and aren't in the tree. So hopefully this all makes sense but if not please let me know and I'll edit the post for clarifications. Thanks to all for any pointers or thoughts... Like I said maybe I'm heading about it in the wrong way from the start... EDIT (Request for xaml) generic.xaml datatemplate: <DataTemplate > <StackPanel Orientation="Horizontal" > <local:FilterCheckbox x:Name="chk"> <TextBlock Text="{Binding Path=Display}" /> </local:FilterCheckbox> </StackPanel> </DataTemplate> usercontrol.xaml (invocation of custom control) <local:MyControl FancyName="This is the fancy name" ItemChecked="DoThisWhenACheckboxIsChecked" <-- this is where the consumer "ties" to the checkbox events ItemsSource="{Binding Source={StaticResource someDataSource}}" />

  • Indirect function call in JavaScript

    - by Art
    There are things like f.call(...) f.apply(...) But then there's this (1, alert)('Zomg what is this????!!!11') "1" does not seem to mean much in this context, the following works just fine: (null, alert)('Zomg what is this????!!!11') (1, null, alert)('Zomg what is this????!!!11') (undefined, alert)('Zomg what is this????!!!11') Could you point to a specific part of ECMAScript which describes that syntax?

  • Is Pharo just a repackaging/rebranding of Squeak?

    - by number5
    I'm trying to learn some Smalltalk. Fisrt found was Squeak, but since it has been removed from Gentoo ebuild tree because of security problem, so I decided to find an alternative. Then I found Pharo through Seaside project, after I downloaded Pharo 1.0 package, there are actually a SqueakVM inside! So, my question is: Is Pharo just a repackaging/rebranding of Squeak? And are those security problem of Squeak (bundle unsecure libs) still applied to Pharo? Thanks!

  • bash: assign grep regex results to array

    Hello everyone, I am trying to assign a regular expression result to an array inside of a bash script but I am unsure whether that's possible, or if I'm doing it entirely wrong. The below is what I want to happen, however I know my syntax is incorrect: indexes[4]=$(echo b5f1e7bfc2439c621353d1ce0629fb8b | grep -o '[a-f0-9]\{8\}') such that: index[1]=b5f1e7bf index[2]=c2439c62 index[3]=1353d1ce index[4]=0629fb8b Any links, or advice, would be wonderful :)

    - by Oscar Godson
    I know how to do plugins, but how do I do nested options like: var defaults = { spacing:10, shorten_to:50, from_start:0, from_end:2, classes: { test:'testing' } }; i know that isn't right, i just dont know how to write the proper syntax when I want to do something like this: $('#breadcrumbs').breadcrumbs({classes{test:'new_example'},spacing:12}) other suggestions are welcome, im in need of the ability to custom class names and there are 7, so rather than making something like test_class, example_class, etc id like it cleaner and neater like the example above.

  • Why use infinite loops?

    - by Moishe
    Another poster asked about preferred syntax for infinite loops. A follow-up question: Why do you use infinite loops in your code? I typically see a construct like this: for (;;) { int scoped_variable = getSomeValue(); if (scoped_variable == some_value) { break; } } Which lets you get around not being able to see the value of scoped_variable in the for or while clause. What are some other uses for "infinite" loops?

  • Reverse PInvoke and create a full unmanaged C# program

    - by Fire-Dragon-DoL
    I know this is a strange question but the idea is simple: I prefer C# syntax rather than C++: -Setters and getters directly inside a property -interfaces -foreach statement -possibility to declare an implicit cast operator other small things... What I really don't know is if is possible to import a c++ dll (expecially std libraries) in C# if I don't use any namespace (even System) The idea is just to write a program using everything that you will normally use in C++ (nothing from CLR so), even printf for example Thanks for any answer

  • How to extend the Eclipse Java Editor to add coloured overlays

    - by Gavin Clarke
    I have an idea for an Eclipse plugin which I've been toying with. I need to be able to extend the Eclipse Java Editor component and add coloured overlays to the code based on pluggable external metrics. Unfortunately there doesn't appear to be any kind of syntax highlighting extension point. Does anyone know how I might be able to extend the exisitng eclipse Java Editor to add custom highlighting rules? Bear in mind I'm new to Eclipse plugin programming so please give as much detail as possible.
