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.

	uses SyncObjs; // one lock for each independent resource var myLock : TCriticalSection; // early during application startup: myLock := TCriticalSection.Create; procedure TMyThread.Execute; begin //... lock it myLock.Acquire; // use the shared resource // unlock it.. myLock.Release; end;
