hi,
I run into a problem that related to bcb6 and adoquery,access datebase.
I create a form with ide, then put an adoconnection component and an
adoquery , a Button onto it.
Then I set the properties of adoconnection to fit the access database, ie.,
db1.
After that I set the properties of adoquery to fit the adoconnection and add
SQL String as simple as "select max(f1) as maxn from t1".
Then add some code to the button:

void __fastcall TForm1::Button3Click(TObject *Sender)
{
   Q1->Close();            //add breakpoint here
   Q1->SQL->Clear();
   Q1->SQL->Add("select * from t1");
}

The problem is:
when the program ran to the breakpoint,I point the mouse to Q1->Close();
it popup a message : "Q1->Close()=E2027 Must take address of a memory
location"
I dont know how to solve the problem and why it arrised.

Thanks in advance !
Frank
