calling thread cannot access this object because a differnt thread

[blar58]

I have problems with thread :

Error on calling "OnStateChange' method: The calling thread cannot access this object because a different thread

This problem happens randomly and is different from computer to computer.

When I want to access the UI I am using the Dispatcher as mentionned in your documentation.

I am also using a few Background workers to do stuff in the background like going to the Yahoo website downloading data or updating different variables using methods.

Do i have to use the Dispatcher for these Background workers ?
Could that resolve the error problem mentionned above ?

Thanks

Hello blar58, and thank you for your question.

So we can further diagnose your system, please start NinjaTrader in Safe Mode. Safe Mode will prevent NinjaTrader from:

• Loading workspaces.
• Connecting on start-up.
• Loading custom assemblies.
• Getting instrument updates from the server.

To enable safe mode, please use the following steps:

• Exit NinjaTrader.
• Hold the CONTROL key and double click the NinjaTrader icon.
• Keep the CONTROL key held down until you see the Control Center.
• You can verify you are in safe mode by going to Help -> About.

Please then just let us know if this occurs at all while you are in safe mode after a couple hours of use. This information will let us isolate what is occurring.
