when I try to execute...

TADOStoredProc *adoSP = new TADOStoredProc(NULL);

this line of code from the thread's context ( in TThread->Execute()
method ).
its ended with an error message:
EOleSysError... 'CoIn�tialize has not been called'

Of course, it works when called from  Thread's constructor ( which belongs
to App. context.) However, I don't want to use this solution because I want
each thread to manage its own TADOStoredProc connection. How can I execute
this line from within thread's context? if I can not, what should I do?

thanks in advance

Try to do exactly what it says;)
Execute  in TThread->Execute()

::CoInitialize();
TADOStoredProc *adoSP = new TADOStoredProc(NULL);
[your stuff goes here]
::CoUninitialize();

HTH,

Alexei is correct.  You have to CoInitialize and CoUninitialize in every
thread which uses COM.
