I have an ASP.NET web application that has been running without any problems for a while. I recently transferred the site to shared hosting and had multiple users start to use the site. The problem I'm experiencing is that when many users are hitting the site at once, occasionaly I will see errors. The 3 most common ones are: "The SqlCommand is currently busy Open, Fetching. ", "Internal Connection Fatal Error", "object reference not set to...

I am trying display the contents of a table in a web page, select
certain rows from that table and then display the fields that I have
selected (now table columns) as text in a Label object. Amazingly I have
managed to display the table - no problem, I can select rows - no
problem, BUT I can't work out how to display more than one of the fields
(now columns in the table in the web page). I can display one field OK,
but not more than one...

While writing a windows service, I've run into a fairly strange problem. I
have a worker proc that gets fired every n seconds using
System.Threading.Timer. This works fine, unless I open an SqlConnection on
it. Just as soon as I do so, the proc fires that time, and never again.
The connection is valid, I can do SQL commands on in with no problems, but
my timer goes away.
Here's a fairly simple console sample that shows the problem....

Variable scope doesn't make sense to me when it comes to Try Catch Finally.
Example: In order to close/dispose a db connection you have to dim the
connection outside of the Try Catch Finally block. But, I prefer to dim them
"on the fly" only if needed (save as much resources as possible). A little
further... I may wish to create a sqlcommand and datareader object ONLY if
certain conditions are met. But, if I want to clean these up in the...

Hi guys -
I have written a form, and a stored procedure to update the said form.
It really is as simple as that. A user can go into the form, update some fields and hit the update button to update the information which is stored in a SQL database.
In testing we noticed that the form was updating correctly but the update mechanism was also updating the first record of the table in the sql database every time. No error messages are on...

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
