The Media Center Sandbox

Hello,

Hope someone can help me.

I have installed the Windows Media Center SDK5.3 and MCMLPal just doesn't run under my MediaCenter. The standalone MCMLPad runs.

With the "MyProject" tutorial,  I have the same result (A simple message under MediaCenter telling me that the application cannot run and has been terminated).

I may have some trouble within my system. Can someone please tell me what things I can check ?

 

Regards

PS: I have a french MDE Home Premium. Visual Studio Express 2005 and 2008.

Are you running MCML Pad inside Media Center and loading your MCML into it, or running your program from the "more programs" section?

Cheers,
Andrew

I can only run the standalone MCML Pad. I can deploy my own MCML application but the result is the same. It exits with no message.

I have made some more tests.

With no code inside the launch method it seems to be ok (nothing happens).

If I let the code that comes from the Visual Studio Template then the application exits with no message. I have tried to put other code such as the creation of a dialog but the resul is the same. I use the Visual Studio Express so I cannot really debug it.

By the way, I have tried to install RSS Plugin by OABSoftware and I have the same result.

It seems to me that I have a real problem somewhere in my installation. But I have no idea how to fix it.

Can you post some sample code files (or a step-by-step of how you are creating them) including your registration information (what goes in your registration.xml file) so we can see what is happening.

Ok,

I have created a new project with Visual C# 2008 Express Edition with the Media Center Application Template.

I have signed the Application.

I have used sn.exe to create a new token and put it into the Registration.xml

Here is the Registration.xml

<application title="TestXavier" id="{33919a07-c58c-454c-b12a-4723da703daa}">

<entrypoint id="{84584e6e-dc58-4099-bd63-7f8b480a6dfd}"

addin="TestXavier.MyAddIn, TestXavier,Culture=Neutral,Version=1.0.0.0,PublicKeyToken=dad82b828520e765"

title="TestXavier"

description="TestXavier Description"

ImageUrl=".\Application.png">

<category category="More Programs"/>

</entrypoint>

</application>

 

Then I have used the DevInstall.cmd for installing the application (in this script, I have made a little modification in order to call the gacutil.exe of the .Net SDK v2.0).

Thank you very much

Regards.

Really going to need the files themselves to understand what's going wrong - something that is in a position to be installed as is, so we can follow the exact same steps you are doing to work out the problem.

Ok,

The 'whole' project can be found here

Hello,

I finally managed to debug the application.

Here is the raised exception :

Does it help ?

I believe this is because you have disallowed applications the ability to gather state information. See http://msdn2.microsoft.com/en-us/library/aa468506.aspx. See if there is a check next to Settings > General > Program Library Options > Access media information from Windows Media Center.
