Stored Proc error

[Pascal]

I use the following function to run a stored proc :

function ExecSp(ProcName : string; InParamsValues: Variant) : Variant;
var
Id : integer;
begin
Result:=Null;

with DM_B.MSStoredProc do
begin
while Executing do
Application.ProcessMessages;

if Prepared then
UnPrepare;

Params.Clear;

Close;
StoredProcName:=ProcName;


// initialiser les parametres en entrée
for Id:=0 to Params.Count-2 do
Params[Id + 1].Value:=InParamsValues[Id];

try
Prepare;
ExecProc;

Result:=Params[0].Value;
finally
if Prepared then
UnPrepare;

Close;
Params.Clear;
StoredProcName:='';
end;
end;
end;
Sommetimes when I call the function
I have the error message " Le connexion est utilisée par les resultat d'une autre commande"

What does it mean ??

Is it possible that you use the same connection (TMSConnection) in the different threads?
