I am using WPF for an image resizing pipeline which has been working beautifully under .NET v3.5. I just upgraded the project to target v4.0 and now all of my resized images are heavily aliased. None of the image pipeline code has changed. Has a default WPF setting changed between v3.5 and v4.0? How do I control the dithering of my res...

There are quite a few applications that allow you to select a box or rectangle of text by sweeping with mouse while the Alt key is pressed. Visual Studio 2010 does this in the code editor, for instance. Emacs does it. Winword does it. We've all seen it. It seems like there must be a standard pattern to follow to encode this behavior but ...
I am working on a 3rd party application that allows plugins to be written in .NET 1.1. I have decided I would like to write my plugin to call a seperate process from the .NET 1.1 plugin (achieved using Process.Start). This is fine- I create a new process that is a WPF app. When I launch this through MSTSC everything works as expected, h...

Hi, I'm repeating same binding parameters for every textbox and they're quite long strings (which is not good for many reasons). And I'm wondering if there's a way to make them shorter? For instance all my controls on forms are using the following binding template: Text="{Binding SourceProperty, UpdateSourceTrigger=PropertyChanged, Va...
I'm using a slider control in WPF to show how much of a file has been read, and to control where to read the file from. The slider binds its Value to a int ProgressValue. I use a timer to look at the current read percentage and set the ProgressValue appropriately. The slider moves to the desired position. As more of the file is read,...
