Get table list from ODBC Connection in .NET
OK, I have an OdbcConnection (Visuall C++ .net) object, connected to an (unknown DB Vendor) ODBC source on the machine. How do I get a list of tables and viewes in the database that I'm connected to? I can run queries, etc, but not get a table list. Thanks!- mbaranski

How to embed interpreter
OK, I've got a VC++ application, and I need to do some data conversions. Now, I'm thinking I want to have a script file, call it x.js. When the data conversion is going to happen, I want my VC++ app to read in x.js, set a variable called inputValue to the original data x.js will modify...- mbaranski

TableCellRenderer still not working right
I have a table cell renderer class, that should color certian cells of a table and leave others the default. The problem is, all the cells take the properties of the last one I set! The text is correct in each of them, but if I set them all blue except the last one, they are all the color of... -

Insert BLOB into ACCESS
I'm re-writing a mysql app that has blob support. I have set up the access database, but can't seem to insert the ADO Object via odbc. Can anyone give me a small example of how to convert a string into an ado object (or whatever) and insert it. Disclaimer: Beware: Studies have shown that... -
Segfault with threads
Anyone have any idea why the following source code segfaults after it exits? It prints Done! (The last line) and then segfaults. All of the threads join up and then it gets a sigsegv.?. This is very confusing. MWB. #include <multimap.h> #include <vector> #include <string> #include <deque>... -
Threaded program segfaults
I'm running a threaded program that segfaults after the threads are joined and before it returns. The last few lines are: pthread_create (&th_a, NULL, producer, 0); pthread_create (&th_b, NULL, consumer, 0); /* Wait until producer and consumer finish. */ pthread_join (th_b, &retval)... -
Fast way to trim trailing whitespace
I'm writing a program that does a huge database import, and after profiling my code, I've found that my program spends over .25 of it's exec time trailing whitespace from each field it imports. I need a (clever) and fast way to remove trailing spaces, and insert a null where the first trailing... -
files and pipes and streams, oh my!
I'm trying to do 3 things: 1. Open a pipe to "mysql -fs" and write to it using << operators: I can't figure out how to use popen() and stuff to get an ostream out of that process. i.e. FILE *mysql; mysql = popen("mysql -fs", "w"); /* Where to go now? */ 2. Open... -
crypt() and salt question.
I'm trying to write a verification program for a web page, and it'll use crypt for a password. Do I have to save the salt that people use, or is there a way to get it from the password that they enter? Or, is it acceptable to use their password as the salt? I could use a little advice here... -
Concurrent File access and CGI scripts
I've a CGI script that takes an email address and a boolean and depending on the boolean adds/removes the address from a mailing list. The mailing list is a flat text file with 1 address per line. When an item is removed, I read every entry except ones that match the address to remove and... -
Re-Direct cerr...
I've got a program that does some stuff, and has logging information being printed to one file, other stuff going to cout, and errors going to cerr. I want to re-direct cerr to a log file, without messing up anything else. Basically, if there is an option specified in the config file, write... -

Weeding out duplicates
I have a table in mysql that has about 60 columns. It has about 50,000 entries in it. For each entry, there are 3 almost duplicate records. By almost duplicate I mean that 57 out of the 60 columns are the same for the 3 rows. I want to be able (with temporary tables and select statements) to... -
