Can I detect and handle MySQL Warnings with PHP? |
|mysql|warning|warnings|php|error-handling| |
I'm dealing with a MySQL table that defines the JobName column as UNIQUE. If somebody tries to save a new Job to the database using a JobName that is already in the database, MySQL throws a warning.
I would like to be able to detect this warning, just like an error, in my PHP script and deal with it appropriately. ... |

How to implement a file download in asp.net |
|asp.net|.net2.0| |
What is the best way to implement, from a web page a download action using asp.net 2.0?
Log files for a action are created in a directory called [Application Root]/Logs. I have the full path and want to provide a button, that when clicked will download the log file from the IIS server to the users local pc. |

Indexed Views in OLTPs? |
|sql-server|database|view|indexed|materialized| |
I'm familiar with SQL Server Indexed Views (or Oracle Materialized Views), we use them in our OLAP applications. They have the really cool feature of being able to usurp an execution plan and remap it to the indexed view w/out having to change existing code.

Why not just use two different membership providers (Windows and Forms, instead of using LogonUserIdentify specifically)?

Yes, my preferred way of doing this would be via PHP. You'd have to set up a script which would load up the file and send it to the user browser. This script would also be able to log the download somewhere (e.g. your database).
For example - in very rough pseudo-code:

The `extern "C" {}` construct instructs the compiler not to perform mangling on names declared within the braces.
