Pascal

procedure Open(const UserID: WideString; const Password: WideString); overload;

C++

__fastcall Open(const BSTR UserID, const BSTR Password);

Description

Call Open to initiate a connection to the database specified in the ConnectionString property.

UserID and Password parameters for Open can be optionally used to pass the user ID and login password to the database server at the same time the request is made to connect.

Copy Code

ADOConnection1.Open('Joe Sixpack', 'SecretWord');

Copy Code

ADOConnection1->Open("Joe Sixpack", "SecretWord");

Alternately, this login information may be passed in the value in ConnectionString.

When explicitly passing login information through either the Open method or the ConnectionString, the LoginPrompt property should be set to false to prevent an unnecessary login dialog.
