Question

I am using PowerBuilder PFC library to login to the database.

n_cst_appmanager/ pfc_open:

IF this.of_LogonDlg() > 0 THEN
    Open(w_myapp_frame)
END IF

n_cst_appmanager/ pfc_logon:

SQLCA.DBMS = "ODBC"
SQLCA.AutoCommit = False
SQLCA.DBParm = "ConnectString='DSN=mytestdb;UID=" + as_userid + ";PWD=" + as_password + "'"
connect using SQLCA;

Now, once the user is logged in, there are few situations that I will need to connect to another database (for example, to copy some data there), so I would like to connect to the other database automatically, without displaying the login window again, therefore I would need to save the username and password of the user.
How can I save it? Do I need to save in the registry? Can you give some example please?

For example, I can get the user id in following way:

s_userid = gnv_app.of_GetUserID()

But I can not get the password. Can someone please help me how i can do it? Thanks a lot.

Answer 1

Actually, now that I’m paying attention to what you need instead of what you asked for <g>, and riffing off of Hugh’s answer, why not just copy the transaction object?

n_cst_String lnv_String

ltr_NewConnect.DBMS = SQLCA.DBMS
ltr_NewConnect.AutoCommit = SQLCA.AutoCommit
ltr_NewConnect.DBParm = lnv_String.of_GlobalReplace (SQLCA.DBParm, "mytestdb", "myotherdb")

If I were doing this, I’d code a copy of all the transaction object fields, just in case the means of defining the connection changes.

I’m assuming the other database is the same type of database in order for this to make sense (so that it uses the same type of DBParm), but either way the principle may apply.

Good luck,

Terry.
