pack-uri

I'm setting a Button's content to an Image. It looks something like this: <Button> <Image Source="pack://application:,,,/NavigationImages/nav_up_left.png" /> </Button> In my project I have a subfolder named NavigationImages and within that folder is the image file nav_up_left.png. When I view the Designer the image appears, however during runtime I get an IOException error saying it cannot locate the resource. The Build Action is set to Resource. Actually, this worked fine in one project. But when I copied it over the another project it fails. This seems like an incredibly simple problem, but

Given a pack:// URI, what's the best way to tell whether a compiled resource (e.g. a PNG image, compiled with a Build Action of "Resource") actually exists at that URI? After some stumbling around, I came up with this code, which works but is clumsy: private static bool CanLoadResource(Uri uri) { try { Application.GetResourceStream(uri); return true; } catch (IOException) { return false; } } (Note that the Application.GetResources documentation is wrong -- it throws an exception if the resource isn't found, rather than returning null like the docs incorrectly state.) (The docs have been

How can I avoid Visual Studio designer errors when a WPF resource is defined in separate project? I have three projects in a composite WPF application: the main application, an "infrastructure" library, and a "module" library. The main application references the other projects via their output DLLs (the projects are not located in a single solution together). I am defining a skin (some brushes and styles in a ResourceDictionary ) in the "infrastructure" library. I would like the main application to select a skin and make it available to the entire application (via MergedDictionaries in App

My assembly includes an image with BuildAction==Resource. I want to obtain a BitmapImage from this embedded resource. I can load a BitmapImage from file like this: var bitmap = new BitmapImage(new Uri(path)); But how to I create a Uri that will refer to an embedded resource image? When I try and create a ' pack URI ' (for example pack://application:,,,/MyImage.png or pack://application:,,,/MyAssembly;component/MyImage.png ), an exception is thrown: System.UriFormatException "Invalid URI: A port was expected because of there is a colon (':') present but the port could not be parsed."
