Failure to follow their security guidelines will result in you not being allowed to process or handle credit cards. That said, the best way to store them is to not store them. If you still have to, then use some kind of encryption using the user's password as part of the key, and don't store the user's password, only an md5 of it. Also, store the password on one machine, encrypted, do the encryption decryption on another machine Try to avoid storing any card and card holder info, and you definitely shouldn't keep in DB the whole data required to authorize transaction. Just take in mind how dangerous this info could be in case of security leak. -- Andrei Kovalevski PostgreSQL Replication, Consulting, Custom Development, 24x7 support Managed Services, Shared and Dedicated Hosting Co-Authors: PL/php, ODBCng - http://www.commandprompt.com/

Hi all,
I'm sorry to bother you with this question, I know it is a C++ ODBC
question. But I'm a bit desperate.
Perhaps I'll be lucky.
I have a table with 2 columns no_char and blobdata were no_char is
number of characters in blobdata. I would like to handle each row from
the result set.
I have got this far:
//Setup selectstatement
strcpy((char*) SQLStmt, Select no_char, blobdata from tab1);
//Execute the statement
rc = SQLExecDirect(dbConnection.StmtHandle, SQLStmt, SQL_NTS);
//Define what to read out from the selection set
rc =SQLBindCol(StmtHandle, 1 SQL_C_LONG, (SQLPOINTER) no, sizeOf(no),
NULL);
rc =SQLBindCol(StmtHandle, 2 SQL_C_BINARY, (SQLPOINTER) blob, no, NULL);
// get the values
while(SQLFetch(StmtHandle) != SQL_NO_DATA)
{
...
...
}
But this will not work since I'm using no in the second statement to
define the blob size, and no is not set yet.
I could solve it by using 2 different select statemen (once for the
size and one for the blob) but that seems to be a bad solution.
Sorry again!

But I respect licences as they are and the ODBCng driver is licenced under the GPL. That doesn't mean that you're not allowed to use it with commercial applications; it just means that you need to be happy to provide the source for it on request. Which is exactly the reason why the LGPL licence was created. So that any software can link against a library without the restrictions of the GPL. Keep in mind, though, that the ODBC driver is not linked to your app. It is only loaded on demand at run time, and can be replaced by any other ODBC driver. So AFAIU your application is shielded from GPL. IANAL of course. Neither am I. However, the GPL FAQ has an entry specially for this case: http://www.gnu.org/licenses/gpl-faq.html#NFUseGPLPlugins If the program dynamically links plug-ins, and they make function calls to each other and share data structures, we believe they form a single program, which must be treated as an extension of both the main program and the plug-ins. In order to use the GPL-covered plug-ins, the main program must be released under the GPL or a GPL-compatible free software license, and that the terms of the GPL must be followed when the main program is distributed for use with these plug-ins. ODBC drivers are loaded by ODBC driver manager - which is also dinamically linked library. Application calls functions from Driver Manager, and then manager goes farther to the driver's level of abstraction. Driver has no information about the parent application, and can't call any functions from it. Driver is not a plug-in, and application doesn't have to worry about its existance. The way I read this section is that linking to a GPL ODBC driver would imply that I have to release my program under a GPL (compatible) licence. This was one of the reasons why I added Postgres support to my program instead of MySQL [1]. They altered the licence for their drivers from LGPL to GPL so that you have to purchase a commercial licence. Rainer [1] In the meantime I am of course glad that I made this decision.

Doing a SQLConnect to connect to a local Postgres server works fine, but if we try to connect to a remote system, the SQLConnect fails, and we get an error code that seems to indicate The value specified for the argument UserName or the value specified for the argument Authentication violated restrictions defined by the data source.. We can connect via pgadmin to the remote system, so we believe all the little .conf files should be correct, but can't get in programmatically. Any pointers on where to look? The logs on the PostgreSQL server would be a good place to start. This sounds suspiciously like a pg_hba.conf misconfig. You might want to verify its correctness. Thanks guys. I can connect to the remote server via pgadmin on a different machine, so I'm pretty sure that the .conf files are correct (that took awhile, but there are very good diagnostic messages when they are wrong). When I set the hba, the encryption is set to MD5 - does that need to be set somewhere on the client side? What version of the PostgreSQL ODBC driver you are using? ---(end of broadcast)--- TIP 2: Don't 'kill -9' the postmaster ---(end of broadcast)--- TIP 5: don't forget to increase your free space map settings
