You need to create a global TCriticalSection and lock / unlock it when you access shared resources with code as shown below.

Create a separate TCriticialSection instance for each resource that can be used independently.
TCriticialSection is defined in unit SyncObjs.


// one lock for each independent resource
  myLock : TCriticalSection;

// early during application startup:
myLock := TCriticalSection.Create; 

procedure TMyThread.Execute;
  //... lock it

  // use the shared resource

  // unlock it..
