blank browser screen after SL3 install

09-11-2009 6:03 AM |

Hi ...

1. Have installed VS2008 SP1

2. Have installed SL plugins/toolkit/SDK etc of SL3

trying my first SL application, opting for install as web app (and no other changes except an addition of a TextBlock into the user control)

SL comes up with a blank browser screen and a popup asking me if I want to install SL. Looking at the solution explorer, I also have a testpage (html) and a testpage (aspx), where it is stated when you create the app, and opt for website, no testpages are created.

Any Idea what is wrong ?? Using XP professional SP3, and the browser which comes along with that.

thx ... Steve

Hi .. took all download steps as indicated in your response ... no problems in install ...

Started on the "helloworld sl app." Result is the same: blank screen, and a SL image inviting me to install SL. Checked the HTML, why is the img in the code ??? code below ...

<%@ Page Language="C#" AutoEventWireup="true" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<title>SilverlightApplication3</title>

html, body {

height: 100%;

overflow: auto;

}

body {

padding: 0;

margin: 0;

}

#silverlightControlHost {

height: 100%;

text-align:center;

}

</style>

function onSilverlightError(sender, args) {

var appSource = "";

if (sender != null && sender != 0) {

appSource = sender.getHost().Source;

}

var errorType = args.ErrorType;

var iErrorCode = args.ErrorCode;

if (errorType == "ImageError" || errorType == "MediaError") {return;

}

var errMsg = "Unhandled Error in Silverlight Application " + appSource + "\n" ;

errMsg += "Code: "+ iErrorCode + " \n";

errMsg += "Category: " + errorType + " \n";

errMsg += "Message: " + args.ErrorMessage + " \n";

if (errorType == "ParserError") {

errMsg += "File: " + args.xamlFile + " \n";

errMsg += "Line: " + args.lineNumber + " \n";

errMsg += "Position: " + args.charPosition + " \n";

}

else if (errorType == "RuntimeError") {

if (args.lineNumber != 0) {

errMsg += "Line: " + args.lineNumber + " \n";errMsg += "Position: " + args.charPosition + " \n";

}

errMsg += "MethodName: " + args.methodName + " \n";

}

throw new Error(errMsg);

}

</script>

</head>

<body>

</a>

</object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div>

</form>

</body>

</html>

Steve,

Try debugging your application in Visual Studio. That way you will know if the application is getting executed or not.

There isn't really a lot to debug. I put a breakpoint on the Initializecomponent() statement, and it does not hit, but I am at a bit of a loss on next steps ... for me, the install looks ok, and in solution explorer, all the necssary files seem to be there ...

Still wondering why there is an img/link in the code inviting to install SL ... still wondering why there is a aspx test page AND an html testpage ...

Hi,

Is it possible the silverlight plugin is disabled by browser? Could you see the silverlight application at http://silverlight.net/?

If you could see the silverlight on otherweb site, then i may be some problem on your silverlight project. Could you upload the sample project to SkyDrive and paste link here?

Thanks,

Hi Mog,,

Website is visible for me. Tried SkyDrive for the first time. Couldnt find an option to upload directories, so I have uploaded 16 separate files of my test project. No changes made to project par addition of a button.

Link --- >

http://cid-e8e9373005f6b7e5.skydrive.live.com/browse.aspx/SL%20Test%20App

Is accessible for everyone. If you really need all files uploaded in their respective directories, tell me how to do it with SjyDrive and I'll reattempt an upload .... thx ... Steve

PS one burning question: are there any restrictions on using Silverlight on windows mobile phones ????
