Well, First of, I�m using BCB 5.0 Ent, W2000. I have a multithreaded software (aprox 150 threads) and one TADOConnection for each thread. TADOConnection *x[190]; x = new TADOConnection(NULL); This array remains until the software stops. If I create one connection in design time (placing the component on the form), the leak appears don�t occur. But the conns cannot handle the high trafic of information. When I run the software in debug mode, step by step, I see the "new" working and the memory grows but when the delete is called, the memory is not released. Question, when I create a String variable, I have to free this variable too when the funcion terminates ?? Ex: String x; x = "Test"; SysFreeString(x); Thanks, Roberto. "Viatcheslav V.
