How to dispose of plots and brushes?

[gubbar924]

I understand that .Net takes care of garbage collection on its own, but I'm not very good at programming and as such I run into issues with my code from time to time where the memory usage starts racking up, especially during testing when I'm constantly reloading/rerunning the script.

Is there a proper way to manually dispose of brushes/plots/whatever else that indicators would normally use?

I see in the help guide that Dispose() can be called on for draw tools and sharpDX brushes, but can anything like that be done with system windows media brushes/solidcolorbrushes, plots, backbrush?
If so, a sample code snippet would help.


thanks!

Hello gubbar924,

Thanks for your post.

You can call Dispose() in State.Terminated that will dispose of anything that is left over.

For example:

else if (State == State.Terminated)
Dispose();

I don't think so.

Hi Paul,

Thank you for the quick reply, I'll update my code based on the ninjascript best practices section and add Dispose() as you suggested.


Thanks!

Hello. tried Dispose() according to advice and manual:

else if (State == State.Terminated) 
{	
   Dispose();
}

and got error:CS103, "The name 'Dispose' does not exist in the current context".

How to fight this disaster?

Hello fx.practic,

Thanks for your reply.

With reference to best practices, you would use something like:

else if (State == State.Terminated)
  {
    // only dispose of object if it has been configured
    if (configured)
    {
        myObject.Dispose();
    }
  }
