HELP ASAP....Windows Service Errors....passing information from .cs file to another .cs file

Sorry to be such a novice about this but..... I have a windows service. It contains two separate files. Both have the same namespace name.

I need to pass "bDisplay" into the other file. I am getting several errors and not sure why or how to solve them does anyone have any help?

How do I access the other file?

ServerSocket.cs *This is where the main server start is so the" private bool m_bIsDisplayed = false;" had to go here so it didn't reset every time.

namespace Listener
{
 private bool m_bIsDisplayed = false;

      public bool GetIsDisplayed()
      {
         return m_bIsDisplayed();
      }

      public void SetIsDisplayed(bool bDisplay)
      {
         m_bIsDisplayed = bDisplay;
      }

}
