Yes, I did figure it out a few hours ago. The DAL was created using a SqlConnection and since a DSN will utilize an OdbcConnection, the SqlConnection object that was created as part of the project did not recognize it. Since I used a visual editor to change from a SqlConnection to a OdbcConnection, I figured VS.NET will do the work for me. Apparently it doesn't. Thanks for your help.

I'm trying to find a way to grab a given rows cell information, for now just the primary key, and store it in a variable to use somewhere else. If I use listbox's I can simply use .selectedValue() and it gives me exactly what I need, but in this case, I'm needing to do it with a datagridview and this attribute doesn't exist. Thanks!

Hi - We have a bunch of tables in our database but no schema was created. Is there a way we could created the schema using the existing tables automatically in SQL2005, just a basic version - or we just have to create it manually?
Is there a feature in 2005 that would do this?
Many thanks.

the database diagram which shows all the relationships between the tables.

Like reverse engineer the tables and create the schema since one was not created while the tables were designed.
thanks,
vani

You can use the "Database Diagram" to create the schema.
thanks for your time.

Expand the node for the database, click Database Diagrams. If you haven't created one before, Management Studio will prompt you to to create the support objects required for diagramming. Right-click Database Diagrams and choose New Database Diagram. From here, select the tables you want in the diagram and click Add. Click Close when you've finished adding tables to the diagram.
Management Studio now arranges the tables so that the key relationships don't cross each other.
Note that key relationships are only shown where you've actually defined a FOREIGN KEY relation between tables. They're normally shown as one-to-many, unless the relationship is between the primary keys at both ends, in which case they're shown as one-to-one.
Stability. What an interesting concept. -- Chris Maunder

Hello,
Do any body have idea of getting complete database backup of mySQL database except this?
SELECT * INTO OUTFILE Path FROM Table
I want just there should be only one backup file of All tables and how to restore that. I am using:
mySQL 4.1 and VB 6.0.
Thanks

use MYSQLDUMP
a built in function for backup all database in mysql.

Hi
you must use it with SHELL commands
i don't know what is this command in VB exactly.but you can search in MSDN for shell.
shell commands are Command Prompt console for executing commands.
i searched for you and i found these:

Why dont you try using MySQL Administrator utility? Its a a free utility available on www.mysql.com. It can perform backups and restores from a graphical interface, and also schedule backups.
"MySQL Administrator is a program for performing administrative operations, such as configuring, monitoring and starting and stopping a MySQL server, managing users and connections, performing backups, and a number of other administrative tasks."
Thanks and Regards,
Aby

Thanks for your suggestion, actually as i mentioned i am using VB 6.0 as front end and mySQL 4.1 as back end. i want there should be an option for taking the backup of complete database from VB form:
user just tell the path where he wants to take backup of database.
any suggestions?
Thanks and Regards,

I can see you've just not translated some Java properly. You should also be aware that Java and SQL are different language types. Java is procedural (i.e. you specify the procedure you want it to take) where as SQL is, for the most part, declarative (i.e. you specify what you want and it figures out the details) - but SQL can also operate in a procedural way also but that is often very inefficient. The procedural elements exist only to suppliment the declarative (set based) elements. If you can use a set based operation then SQL is very efficient.
What you are doing here is imposing a procedural model.

can anyone tell me as wat could be the reason??
NOTE: there are no conditions in the script that ll prevent the insertion happenning
its a bit urgent..
thanks in advance..
