Silverlight install problem

It stops playing or behaves very strangely. The symptoms are: Silverlight works fine initially. On a Mac, Silverlight can get a bit confused if you choose to use your non default output. If it's still not working then try setting Allow ActiveX Filtering: Disable Script Activex controls marked safe for scripting: Enable.Run ActiveX controls and plug-ins: Enable.Initialise and script Activex controls not marked as safe.Download unsigned Activex Controls : Disable.When changing these, you will need to close all IE windows before your new settings will apply.Ĭheck the Enable Protected mode check box and read the message next to it. Silverlight plug in is an Activex control. One of the keys to understanding how to troubleshoot this is realising that the Basically, you have settings which are stopping Silverlight from showing up. The most common cause of that on Windows with Internet Explorer is the browser security settings. The thing telling you to install Silverlight is just a standard fallback picture you will see if the Silverlight object cannot render in the page. There is no intelligence or logic applied. You see the link to install Silverlight when the control fails to load. Install Silverlight When Already Installed If you're looking at a screen full of tiles - this is your problem. You need the desktop version of internet explorer. In which case, is this an ARM based machine? Win RT does not support Silverlight. There are a number of possible explanations for seeing this message. This Browser Doesn't Support Silverlight

( Windows IE )You get to the desktop mode by selecting the desktop tile on Win 8.0 or in win 8.1 there's a little window icon bottom left you can click. If you’re looking at a bunch of tiles then that isn’t desktop. You don’t have that option at all if you are using a Win RT device such as a Surface ( without a “pro” on the end ). In the "Search web and Windows" box on the taskbar.Ĭheck your operating system and browser are on the list:Ĭompatible Operating Systems and Browsers.Īlthough Internet Explorer is one of the more reliable browsers with Silverlight it’s only the version on the desktop view of Win8/8.1 which is compatible. You should use Internet Explorer on Windows 10. On Windows 10 the default browser is Edge, this is incompatible with Silverlight and MS will not be adding Silverlight support. Other companies seem to have decided that means they’re not going to support Silverlight.įor example, it just won’t work on recent macs using Chrome. Silverlight is currently in end of lifetime support from Microsoft. Obviously, if you see something else like a blank page or a message to install silverlight etc then you have proven there is a problem with your Silverlight and browser combination. If you see a video player straight away then that is rendered using Silverlight. If Silverlight works for you at all then the chances are you need to be talking to whoever provides the website you're trying to use.įollow

Unit testing is important, even for Silverlight applications. At my job, I insist that every application contain at least some unit testing (that doesn’t mean that every application does, but I’ll keep insisting), and that we maintain a minimum of 40% code coverage. Normally, I implement unit testing with NUnit. But NUnit doesn’t work with Silverlight:Fortunately, there are other options. For one, we have the Silverlight Unit Test Framework:The Microsoft Silverlight Unit Test Framework (Microsoft.Silverlight.Testing) is a simple, extensible unit testing solution for rich Silverlight 2 applications, controls and class libraries.The biggest problem I see with the Silverlight Unit Test Framework is that it lacks the ability to automate the tests. Once the tests are added, someone has to run them and examine the results. In other words, there’s no “nunit-console.exe” to run as a post-build step. What I really need is NUnit for Silverlight…Enter Jamie Cansdale of TestDriven.NET fame, who rigged up a Visual Studio NUnit template that includes a Silverlight-compatible version of the NUnit.Framework assembly. The main drawback is that Jamie does not provide the converted NUnit source code. But if you think of this as a stop-gap measure until NUnit 3.0 arrives, then it should work nicely for you.All that being said, as Silverlight developers we are presented with two unit testing options:Jamie’s Silverlight NUnit port for automated, every-time-you-build-unit testsThe Silverlight Unit Test Framework for integration and GUI testingThere may be others, but this is what I’m principally going to focus on for now.Jamie’s Silverlight NUnit port: How to Get StartedDownload Jamie’s .vsi template linked to on his post. Double-click the .vsi to install, selecting “Yes” when the warning dialog pops up.Open any Silverlight project (or create a new one), right-click to add a new project, and you’ll see:That gives you the following project layout:SilverlightTests.cs starts with a basic unit testing framework which you can then start modifying and adding to: 1: using System; 2: using System.Reflection; 3: using NUnit.Framework; 4: 5: namespace SilverlightNUnitProject2 6: { 7: [TestFixture] 8: public class SilverlightTests 9: { 10: [Test] 11: public void SystemVersion () 12: { 13: Assembly systemAssembly = typeof (Uri).Assembly; 14: StringAssert.Contains ("=2.0.5.0,", systemAssembly.FullName, 15: "Check we're testing a Silverlight 2.0 assembly"); 16: } 17: } 18: }If you’ve used NUnit before you should be in familiar territory now. I like to set “nunit-console.exe” to run as a post-build step so that every time I perform a build, the unit tests are run. Something like:“C:Program FilesNUnit 2.4.7binnunit-console.exe” $(TargetPath)That’s it for Jamie’s Silverlight NUnit port. I hope he either makes the source available or integrates the functionality into TestDriven.NET.The Silverlight Unit Test Framework: How to Get StartedThere’s a lot of great tutorials on how to get started using the Silverlight Unit Test Framework. Jeff Wilcox, who is on the Silverlight Toolkit team, posted the introductory one back in March, 2008. It’s good stuff, and worth a read. I won’t try to repeat his or others’ work, but instead just point out a couple of things, especially as we are

I have a simple silverlight application and i need to add the web browser scroll bars for it. (scroll bars not inside my silverlight app)So I have html:html, body { height: 100%; overflow: auto;}body { padding: 0; margin: 0;}#silverlightControlHost { height: 100%; min-height:600px; min-width:800px; text-align:center;} And i faced with next problem: vertical scroll bar works not properly when scroll bar is enabled silverlight application not fits content of page. (Red arrow on screen shows the area without silverlight application) I dont now how to solve this problem.Width fits normally. Inside silverlight application content set to stretchImage:I will be grateful for any information We had the same problem in IE and Chrome and solved it using Javascript:Add the following Javascript to your Silverlight test page.window.onload = resizeObject;window.onresize = resizeObject;function resizeObject() { var height = document.getElementById('silverlightControlHost').offsetHeight; document.getElementById('silverlightObject').height = height;}Give your OBJECT tag the ID 'silverlightObject'.Test it. Have you tried putting a overflow:auto; in div #silverlightControlHost style?and remove the property from html,body
