How do you set Image.Source in Silverlight(Code behind)

由 北战南征 提交于 2019-12-18 18:49:47
问题 I am dynamically generating an image through code-behind in Silverlight and apparently the image source doesn't accept a string or Uri as a path. How can I set the source? 回答1: How do you mean it won't accept a string as source? Are you not able to do this? Or are you saying your image is in memory and you don't know how to reference it? this.MyImage.Source = new BitmapImage(new Uri("/MyNameSpace;images/someimage.png", UriKind.Relative)); 回答2: // create a new image Image image = new Image();

问题 I am creating a Windows 7 mobile Silverlight project. I use Rest api for authentication using a class say Authentication .

Does anyone know of a way to easily convert a PDF to a docx format programmatically

由 佐手、 提交于 2019-12-18 18:07:30
问题 We have a couple 3rd party systems that give us PDFs. We would like to convert those PDFs for display on the web without using an Adobe product. Ideally we would like to use Silverlight to render the PDFs but are having trouble converting from a PDF to Xaml or using docx format as a middle man. There are lots of libraries that give PDFs but that is not what we need. If there is a library out there that does this, a .net lib would be preferable but we can run the conversion using the command

问题 Hello I want to post some data from silverlight to a website. I found the following link and it works... However.... This example was so elaborate it made my eyes hurt.

问题 I am trying to write a simple Silverlight media player, but I need the timestamp to be hh:mm:ss:ff where FF is Frame count. I used a timer in order to get ticks and calculate the frame I am in, but it seems very inaccurate. How can I count reliably the frame I am in? Does anyone know of a free Silverlight player that will do that? 回答1: Silverlight is designed to update at irregular intervals and catch-up any animation or media playing to the current elapsed time when the next frame is
