问题 Icons have been provided in the SDK for either "Light" or "Dark" depending on the theme set on the phone. On the application bar when the theme changes the icons automatically change with it. Also, when you press the button the image is reversed (so it's still visible) no matter which theme you're on. I can easily figure out how to change the icon based on the current theme. However what's no easily figured out is how to change the icon when the button is pressed. To be more clear. Let's say

问题 I have a silverlight app which can be installed as out-of-browser . I've defined the Height and Width in the main UserControl . I've defined the same Height and Width in the OutOfBrowserSettings.xml file. But the user can still resize the out-of-browser frame window. How do I prevent this? 回答1: The window hosting the Silverlight application cannot be controlled by the application when it is running with normal permissions, that would be a security issue. However, if you install the OOB

问题 I'm using a WebClient to get infos asynchronously from my web service : wc.DownloadStringCompleted += DownloadStringCompleted; wc.DownloadStringAsync(service); I works fine, but I think the DownloadStringCompleted method is working on the UI Thread, and since i'm doing a lot of parsing there, my page takes a few seconds to appear. However, since I have so fixed data and a progress bar, I would'nt mind have it appearing instantly. How could I perfom this ? Thanks ! 回答1: Use HttpWebRequest

问题 I have been searching high and low for a way to get my silverlight application talking to the COM port on my local computer. Has anybody out there been able to get Silverlight to successfully connect to the COM port of you local computer? If so can you point me to the documentation. 回答1: This can not be done with Silverlight. Why not just use a standard .NET desktop app? If you need to easily deploy over the web, just use Click-Once for deployment. 回答2: There's no access to computer resources

问题 My organization is considering which technologies to use for our next generation of systems. We will be using .NET, but have not decided which user interface technology is best. Silverlight and WPF seem to be the most appropriate options. Can someone share the pros and cons of each approach? 回答1: As Gabriel (and Reed) mention, Silverlight is a slimmed down version of WPF. WPF is intended primarily for desktop applications, and it has advanced features around layout, animation, and data

问题 I set IsTabStop to false on a text box and I know that this makes the control unable to receive focus, but according to the Silverlight Forums, it should still be able to receive mouse events. I have the MouseLeftButtonUp event wired and a breakpoint in my tbxTotal_MouseLeftButtonUp method, and it never gets hit during debugging. The thread in the SL Forums is pretty old now, so maybe this was changed in an update somewhere. I want a text box that can't be tabbed to, but is still editable.
