If I use exactly the same images in my main app they are shown correctly. If I use them in the search charm their quality is drastically decreased. What am I doing wrong? I tried another sizes, another picture formats, still the same. I tried another image (photo below) and that one looks OK.

问题 I want to show album art in the windows 8 media control, like this: However, MediaControl.AlbumArt has type Uri, instead of type ImageSource like I expected. Does the album art embedded in a music file even have a URI? I've tried providing a URI to the file ("file:///C:/Rest/Of/Path.mp3") (an immediate exception results), but other than that I don't even know where to start. Maybe I'm supposed to write the album art to a temporary file and point at that (feels like the wrong way to do it, but

问题 Does anyone know if Powerbuilder 10 is compatible with Windows 8 (Both the IDE and the runtime module)? It seems like 11.5 is officially supported, but I couldn't find any info on PB 10's compatibility on Windows 8. If it isn't, any tips on the migration process from 10->Further version? (Anything particular we have to watch out for?) 回答1: You should have no problem with running PB10 applications on Windows 8, appart perhaps not being not fully compliant with Win8 standards (concerning the

问题 We are working on a windows 8 native application that will need a feature to switch between an administrator account and an less privileged account and then back again.
