timer ambiguous

[Dave]

I trying to setup a time. The following code is in a function,

Timer stateTimer = new Timer(ab(), null, 1000, 1000);

I have included

using System.Threading;

at the begining of my code. When I try to compile I receive the error,

'Timer' is an ambiguous reference

What is the problem?

You should put the full namespace path in your constructor.

ex:
System.Threading.Timer stateTimer = new System.Threading.Timer(ab(),
null, 1000, 1000);

There are three timers:
System.Timers.Timer
System.Windows.Form.Timer
System.Threading.Timer

Decide which one you want to use and write explicit definition, like:
System.Timers.Timer stateTimer = new System.Timers.Timer(ab(), null, 1000,
1000);

That fixed my original problem. I' ve changed the code to;

System.Threading.Timer stateTimer = new System.Threading.Timer(ab(), null,
1000, 1000);

Now I'm receiving the error, "Argument '1': cannot convert from 'void' to
'System.Threading.TimerCallback'

My function is simply as follows, which simply increments a counter;

public void ab()
{
t_count +=1;
}

I don't see that thee is anything to convert. What's causing this error?

Are you sure you need the threading timer? it is more complicated than the
others.
If you still want to use it:

TimerCallback timerDelegate = new TimerCallback(ab);
Timer timer = new Timer(timerDelegate, null, 1000, 1000);

public void ab(object Status)
{
t_count +=1;
}

It sounds like the stateTimer object is being declared in the scope of
your start button code. You'll need to declare it more global in the
scope of your class so that the stop button code has visibility of
the object.
