  - by Futur

  Hi All, I have 4 database catalogues in my app, i will be switching the four catalogues. When i start the app, i read the NSUserDefaults and try to load the default catalogue in the memory, but in the first time this doesnt happen. Instead i get null values returned first time just because the DB connection is not successful for some unknown reason, the debugger is unable to go there too. But the app starts up the next time, the values are fetched successfully. Please help

  - by Edward Tanguay

  In my Silverlight application, I load all the images I need at application start and store them in a dictionary. Then as I need them I pick them out of the dictionary and attach them in XAML trees etc. However, I have the problem that if I attach an Image object to a Grid, then want to use that image again, it tells me: The image element is already a child of another element. How can I run through my dictionary and "detach all images from parent XAML elements"?
