Timers in windows8 using c++

Just getting a basic timer in c++ isn't as easy as in C#.
So I'm stepping myself through this and documenting my findings.
I just want to start a timer on a touch event to fade out a control when the finger leaves the screen.
So to do this I want that control to wait for a few seconds before going back to it's home position.
I could use wait, but then the rest of the screen locks up till after the wait.
Since I want to use multi touch features this is bad.
The best way to do this *I think* is concurrency and the call function, but finding a good example for this has been really hard.

http://msdn.microsoft.com/en-us/library/dd504870.aspx I started here to get a start on the concurrency run time.
Also writing a windows 8 metro app in WPF, so that's adding some little hitches here and there with various features that I can and can't use.
Also can't use 3rd party libs like boost.asio which is because the client doesn't like those things, doh.
Google for running multuple tasks and I get to
this link http://msdn.microsoft.com/en-us/library/dd728065.aspx.
In here was the following code snippet...

int wmain()
{
// Create a call object that prints a single character to the console.
call<wchar_t> report_progress([](wchar_t c) {
wcout << c;
});
// Create a timer object that sends the dot character to the  
// call object every 100 milliseconds.
timer<wchar_t> progress_timer(100, L'.', &report_progress, true);
wcout << L"Performing a lengthy operation";
// Start the timer on a separate context.
progress_timer.start();
// Perform a lengthy operation on the main context.
perform_lengthy_operation();
// Stop the timer and print a message.
progress_timer.stop();
wcout << L"done.";
}

This looked pretty helpful. There's the call and the timer functions that look pretty good.
Unfortunately in report_progress([] (wchar_t c) {...} there's a lambda and I get the following error

Error: a local lambda is not allowed in a member function of a WinRT class.

damn.

So now what? Dig around more for timer class in WinRT and I find

What's going on here?

Instead of SetTimer(), you should use Windows::UI::Xaml::DispatcherTimer.
See the MSDN article here: http://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.xaml.dispatchertimer.aspx.

Okay, so lets go there.
http://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.xaml.dispatchertimer.aspx.
and...

Server Error in '/' Application.

Crap, so look up xaml dispatch timer and get to  http://msdn.microsoft.com/en-us/library/windows/apps/xaml/windows.ui.xaml.dispatchertimer
I think im getting closer. This is looking a bit better, something that seems to be useful, finally.
I just used this in C# for the previous version of the interface I was building in C#, perfect!
I think I can use this. The example is in C# so i need to find a C++ example,
get to this http://social.msdn.microsoft.com/Forums/en-US/winappswithnativecode/thread/edff3bf2-4223-49fe-b66b-119702458700
The thread goes through a few iterations. I get to what I think is really close but get stuck at.

timer->Tick += ref new  Windows::Foundation::EventHandler<Object^>(this, &DispatcherTimer_Tick); 

I get an error:

object not needed for the specified function

So I delete "this" and the following "," and that seems to do the trick.
No more errors...
So I start my vars with...

Windows::UI::Xaml::DispatcherTimer ^SomeTimer;

and then add in a way to count ticks...

int Ticks;

and when the xaml page is initialized i add in

XAMLPage()
{
InitializeComponent();
//other init stuff...
SomeTimer = ref new DispatcherTimer;
SomeTimer->Tick += ref new  Windows::Foundation::EventHandler<Object^>( &Timer_Tick); 
TimeSpan t;
t.Duration=1;
SomeTimer->Interval = t;
}

Then I precede the page initialization with my Timer_Tick function that looks something like...

void Timer_Tick(Platform::Object^ sender, Platform::Object^ e)
{
OutputDebugString(L"TIMER!!!");
Ticks++;
if(Ticks>10)
SomeTimer->Stop();
}

so after 10 ticks the timer stops.

I'm far from a super c++ programmer, and mostly a C# or unrealscript game programmer guy.
I've been doing this stuff for a while and I learn fast, and that's pretty important.
I do these little process blog entries to help myself out.
It's like a breadcrumb trail I can follow to avoid backtracking.
Hope this helps someone.
