[Mono-list] Npgsql.dll

[Carl Olsen]

Hi Francisco,

My web page is running on Apache and Linux using C# as the page language and
PostgreSQL as the database. I'm executing a stored procedure that creates a
temporary table and then returns the data from the temporary table to a
datagrid in the web page. A temporary table only exists while a connection
is open, so I open and close the connection in the page load event handler.
The problem I'm having is that when I hit the Refresh button in Internet
Explorer 6, I get an error message saying that the temporary table already
exists. I always thought the Refresh button reloaded the page, but
apparently not. How can I capture the event that occurs when the Refresh
button is selected? 

By the way, I thought Npgsql.dll was installed in the global assembly cache
by default in SUSE 9.2 Professional.  I just used Red Carpet to upgrade to
Mono 1.1.x, but it appears that Npgsql.dll is installed in the global
assembly cache.  That's where I copied it from to get it into the bin folder
of my web application.  I copied the Npgsql.dll file from
/usr/lib/mono/Npgsql/1.0.5000_0.5d8b90d52f46da7

Hi Carl, congratulations!!

Did you add Npgsql.dll to global assembly cache?

If not, you must put your assemblies in bin folder in order to asp.net
find them.

Very good to hear!
