• How to show printer properties/preferences dialog?

  - by Patrick Klug

  I can't figure out how to properly show the printer preference dialog of a given printer so that the user can change the printer settings. Most of the examples that I can find online manage to show the dialog but any changes the user might make are lost which makes it useless. Example: http://www.codeproject.com/KB/system/PrinterPropertiesWindow.aspx (I tried to change the code as suggested by BartJoy but that didn't fix it) Does anyone know how to do this properly?

• need a regex to parse a csv file with double quotes in php

  - by Brandon G

  Trying to parse a csv file that has all the data wrapped in double quotes, because there may be commas in the double quotes. Looks like this: $songs = '"1, 2, 3, 4 (I Love You)","Plain White T's","CBE10-22",15,"CBE10-22","","","CB",984,"","10/05/10"'; $regResult = preg_match( "", $songs, $matches ); I can't figure out a regex that will return the data between the quotes as the matches. I'm sure there is some regex master that can help me with this.

• WPF MVVM: Convention over Configuration for ResourceDictionary ?

  - by Jeffrey Knight

  Update In the wiki spirit of StackOverflow, here's an update: I spiked Joe White's IValueConverter suggestion below. It works like a charm. I've written a "quickstart" example of this that automates the mapping of ViewModels-Views using some cheap string replacement. If no View is found to represent the ViewModel, it defaults to an "Under Construction" page. I'm dubbing this approach "WPF MVVM White" since it was Joe White's idea. Here are a couple screenshots. The first image is a case of "[SomeControlName]ViewModel" has a corresponding "[SomeControlName]View", based on pure naming convention. The second is a case where the ModelView doesn't have any views to represent it. No more ResourceDictionaries with long ViewModel to View mappings. It's pure naming convention now. I'm hosting a download of the project here: http://rootsilver.com/files/Mvvm.White.Quickstart.zip I'll follow up with a longer blog post walk through. Original Post I read Josh Smith's fantastic MSDN article on WPF MVVM over the weekend. It's destined to be a cult classic. It took me a while to wrap my head around the magic of asking WPF to render the ViewModel. It's like saying "Here's a class, WPF. Go figure out which UI to use to present it." For those who missed this magic, WPF can do this by looking up the View for ModelView in the ResourceDictionary mapping and pulling out the corresponding View. (Scroll down to Figure 10 Supplying a View ). The first thing that jumps out at me immediately is that there's already a strong naming convention of: classNameView ("View" suffix) classNameViewModel ("ViewModel" suffix) My question is: Since the ResourceDictionary can be manipulated programatically, I"m wondering if anyone has managed to Regex.Replace the whole thing away, so the lookup is automatic, and any new View/ViewModels get resolved by virtue of their naming convention? [Edit] What I'm imagining is a hook/interception into ResourceDictionary. ... Also considering a method at startup that uses interop to pull out *View$ and *ViewModel$ class names to build the DataTemplate dictionary in code: //build list foreach .... String.Format("<DataTemplate DataType=\"{x:Type vm:{0} }\"><v:{1} /></DataTemplate>", ...)

• Animated transitions for jQuery UI's sortable

  - by Heilemann

  Just out of curiosity, as I haven't been able to find anything anywhere; does anyone know of a way to get jQuery UI's sortable function to animate its sorting? What I mean is, when you move an element around the sortable parent, its children, the sortables, skip around instead of smoothly animating to their new position, which besides from being an eyesore can also make it a bit difficult to figure out what has moved where. There's obviously no default option for this, but I was hoping that perhaps someone, somewhere, had a neat solution.

• Genetic Programming Online Learning

  - by Lirik

  Has anybody seen a GP implemented with online learning rather than the standard offline learning? I've done some stuff with genetic programs and I simply can't figure out what would be a good way to make the learning process online. Please let me know if you have any ideas, seen any implementations, or have any references that I can look at.

• Using MOA to classify new examples?

  - by Sam Zetoloth

  I'm trying to use the java machine learning library MOA to train on a training data stream, then predict classes for a test data stream. The first part works fine, using (for example) java -cp .:moa.jar:weka.jar -javaagent:sizeofag.jar moa.DoTask "LearnModel -l MajorityClass -s (ArffFileStream -f atrain.arff -c -1) -O amodel.moa" But then I cannot figure out how to use the trained model (amodel.moa) on another stream (atest.arff) to predict the classes. Has anyone done this before?

• Javascript Regular Expressions - Replace non-numeric characters

  - by user271619

  This works: var.replace(/[^0-9]+/g, ''); That simple snippet will replace anything that is not a number with nothing. But decimals are real too. So, I'm trying to figure out how to include a period. I'm sure it's really simple, but my tests aren't working.

• Lazy Loading with Ninject

  - by devlife

  I'm evaluating ninject2 but can't seem to figure out how to do lazy loading other than through the kernel. From what I can see that kind of defeats the purpose of using the [Inject] attributes. Is it possible to use the InjectAttribute but get lazy loading? I'd hate to force complete construction of an object graph every time I instantiated an object.

• Silverlight: Set Items Widths in ItemsControl to Stretch

  - by Tom Allen

  I've got an ItemsControl which fills from top to bottom, but I can't get it's child items to occupy the whole width of the ItemsControl: I basically need to stretch the green bits to fill the width of the control (as shown by the blue bits). I've tried things like setting the HorizontalAlignment property of the template item to Stretch and I've even tried binding it's Width property to the ItemsControl Width, but neither worked. Should be a straight forward one, but it's something I just can't quite figure out...

• How do I convert HTML to RTF (Rich Text) in .NET without paying for a component?

  - by Josh Kodroff

  Is there a free third-party or .NET class that will convert HTML to RTF (for use in a rich-text enabled Windows Forms control)? The "free" requirement comes from the fact that I'm only working on a prototype and can just load the BrowserControl and just render HTML if need be (even if it is slow) and that Developer Express is going to be releasing their own such control soon-ish. I don't want to learn to write RTF by hand, and I already know HTML, so I figure this is the quickest way to get some demonstrable code out the door quickly.

• Progress bar in notification bar

  - by android_dev

  Hello everybody, I would like to put a progress bar in the notification bar. The idea is showing the progress bar while the program uploads a file to a server. Everything else is ok, but I can not figure out how to refresh the progress bar inside the notification. Does anybody knows any pattern to play with? I mean, where I should refresh the progress bar, in a service or activity and so. Thanks in advance.

  Ok, so I'm trying to select an amount of rows from a column that holds the value 3, but only if there are no rows containing 10 or 4, if there are rows containing 10 or 4 I only want to show those.
