Is this ok to do?

Im assuming this is ok to do? I have a situation where I need to protect the
DB resource  and Screen vars at the same time.. Only once in a blue moon..


EnterCriticalSection(GlobalVars_CS);
EnterCriticalSection(DB_CS);
Try


Finally
   LeaveCriticalSection(GlobalVars_CS);
   LeaveCriticalSection(DB_CS);
End;
