The Media Center Sandbox

Hey.

When I Invoke to a Method in my C# Class and committ and String from mcml (e.g. name=[Labnel.Content]) to this Method, the string is in this format:

{\\rtf xxx}

Is it Rich Text Format?
And how can I avoid this format (I only want to receive xxx)

regards, tronic

Can you post the MCML and C# code that does this, as this isn't normal behaviour of MCML.

Cheers,
Andrew

Hey.

C#

 public void Register(string name)
        {          

            here is name = {\\rtf xxx}

        }

So just to check I understand, you are passing in the values in the repeater that ultimately get passed back to the Register method as "name".  What does the data look like?  Is it just entered as strings in code, or do you get it from somewhere?   Could it be in a character encoding that Media Center doesn't like, so converts it to RTF?

Hey Andy.

I get the Data from an  Dictionary<TKey, TValue> and fill it with an while loop to an ArrayListDataSet.
I have checked the data by debugging. They are normal strings when they put into the ArrayListDataSet.
Only when I hit enter to invoke Register( string name)....they return to the C# in this strange form ({//rtf xxx}.

regards, tronic

Is "({//rtf xxx}" exactly what it says, or are you putting the xxx as shorthand for what it actually says?

If the latter, can you post one example of what it looks like?  I'm thinking somewhere along the line, the data you put into the .Content is being converted in to RTF because it can't be dealt with properly, just not yet sure why.

Cheers,
Andrew

An Example is "Alice". That will be put into the ArrayListDataSet. A normal String.
This Array will be displayed by an Repeater and is scrollable.
And when it returns to C# (because of the EnterHandler Invoking) it looks like this: {\\rtf Alice}.

Thats a short abstract.

Maybe, it would be the Repeater?! When he gets the data from the Property. But when I look inside the Property by debugging the Strings are all ok.

I have to say I'm completely stumped at the moment - can you create a complete project that replicates the issue and post it, and I'll have a look to see if I can work out whats causing it.

Cheers,
Andrew

Hey.

Here is an Project.

http://rapidshare.com/files/126558168/App.zip.html

You must run it inside of Media Center. When you hit Enter on any Name you will get a Dialog with the Name....without problems. looks like all ok. but when you debug the C# Code and show inside the variable "name" at the Method Register you will see the problem {\\rtf xxx}...thats what return from Media Center.

Its really scary. The Dialog displays all ok, but back to Code (for processing the data) the wrong string.

regards, tronic

Well that was a new one on me... the issue is that you are bring back the content which apparently is stored in RTF format (which I didn't know).  If you change

<Invoke Target="[TestClass.Register]" name="[Label.Content]"/>

to

<Invoke Target="[TestClass.Register]" name="[Description]"/>

everything works fine.

Cheers,
Andrew

Thanks. It works fine.

Good to know. It is very strange that these strings are stored in rtf in this part of Text Element :).

problem fixed :)

thanks a lot, tonic
