I tried this using Npgsql 1.0, but I can not find any way in Npgsql to specify the client certificate that should be used for the connection.
I did manage to get server certificate verification on the client working, and I also did get all the verification working using the commandline db admin tool psql, but this did not help me further in getting it to work with Npgsql.
So, how would I connect my .NET app using TLS client & server authentication to a PostgreSQL database?
Is there maybe a newer/other data provider that does support this?

automatically generated password. However, sometimes what I notice is that it times out sometimes and the new user simply won't receive the email with the password.
Alright, so I'll display a message indicating that the mail did not go through but the user is created.
Therefore, the sys admin has 3 options:
a) Reset the password for the user and hope another SMTP mail is sent with the auto-generated password.
b) Delete and recreate the user.
I could rollback the user creation if the smtp is not created but what is the best practice to tackle this problem?
I'm thinking that I should retry sending the email 3 times with a timeout period of 5 seconds each. So 15 seconds would be the worse case scenario.

I know that Spring provides facility where we can implement Validator interface and write validation logic in validate method. But this will be restricted to only web requests coming through spring controller.
I would like to develop the validation framework which can be utilized during web-services calls.
In other words, the framework can remain and be called independently without the need of implementing Validator interface and then too it can be automatically integrated into Spring MVC flow.
Hope you get my point.

2. Some cut lengths are more common than others. Anything less than 2 feet is considered scrap, so we'd rather not make a cut that leaves a large piece of scrap.

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.
IE. Let's say I had a SPROC that was a really expensive join.
>SELECT [SOME COLUMNS]
FROM Table1 INNER JOIN Table2 [DETAILS]
INNER JOIN Table3 [BUNCH MORE JOINS]
...
If I authored an indexed view that held a similar result set then the Query Optimizer will very likely send the SPROC to my indexed view as opposed to the base tables and I get a big performance increase.
Now say I wanted to use indexed views in an **OLTP!?** I mean most OLTPs (like this site) are relatively read heavy, if they have expensive joins then we could speed them up a ton AND potentially reduce locking contention (http://www.codinghorror.com/blog/archives/001166.html). Even better is you wouldn't have to change any code, just author the indexed view.
But this also means the database gets bigger since we need to keep a copy of these data in the indexed view...
**Has anyone ever used indexed views to solve contention or speed issues in an OLTP? How come I've never seen this in use?**

My university does not allow our student-mailbox to forward to a private e-mail account (everybody uses either Gmail or Hotmail here). It's a pollitical thing, not technical. We do have IMAP access to the mailbox. I would like to have a service wich dowloads the mail trough IMAP, and forwards. And it would be nice to scale it, so thousands of students can use it. Eventualy, I want to build a public signup page, and have it processed automaticly from there.
So far, I've made a decent PHP script wich connects, downloads headers and bodyparts, and ties it all together. I have two problems with that.
1) I'm downloading all kind of parts, and sticking them back together. I hope that every exotic attatched file, weird encoded piece of text and every tipe of header survives this. I'm not even sure I have the complete header.
2) The to: e-mailadres becomes the private e-mailadress, not the original student e-mailadress. I think this is lame, and unconveniant in searching and archiving.
Is the PHP script the way to go? Is there a trick using a particular linux mail service/deamon? Does IMAP have a 'forward' command, I'm missing? | imap | e-mail | forwarding | web-services | web-applications | null | open | IMAP forwarder

We do have IMAP access to the mailbox. I would like to have a service wich dowloads the mail trough IMAP, and forwards. And it would be nice to scale it, so thousands of students can use it. Eventualy, I want to build a public signup page, and have it processed automaticly from there.
So far, I've made a decent PHP script wich connects, downloads headers and bodyparts, and ties it all together. I have two problems with that.
1) I'm downloading all kind of parts, and sticking them back together. I hope that every exotic attatched file, weird encoded piece of text and every tipe of header survives this. I'm not even sure I have the complete header.
2) The to: e-mailadres becomes the private e-mailadress, not the original student e-mailadress. I think this is lame, and unconveniant in searching and archiving.
Is the PHP script the way to go? Is there a trick using a particular linux mail service/deamon? Does IMAP have a 'forward' command, I'm missing? | 0 |

This [blog][1] has all the exact information I need including vbscript samples.
If you have any similar C# code, please post it.
That will give me a good lead on writing a small system tray application which will poll the Active Directory and show the percentage in real time.

Right now, I'm placing the cal values into registry keys that get put into the OS image at build time. That works fine for the monitor that I get the original cal values from, but when I load this image into another system with a different monitor, the touchscreen pointer location is (understandably) off, because the two monitors do not have the same cal values.
My problem is that I don't know how to properly store values into the registry so that they persist after a power cycle. See, I can recalibrate the screen on the second system, but the new values only exist in volatile memory. I suggested to my boss that we could just tell our customer to leave the power on the unit at all times -- that didn't go over well.
I need advice on how to save the new constants into the registry, so that we can calibrate the monitors once before shipping them out to our customer, and not have to make separate OS images for each unit we build.
A C# method that is known to work in CE6.0 would be helpful. Thanks.

So, our hypothesis is that the ASP classic pages are not tripping whatever mechanism in the forms authentication framework that resets the inactivity timer.

Users can create and remove columns from the table through this interface. This legacy system is using ADO 2.8, and is using SQL Server 2005 as its database (you don't even WANT to know what database it was using before the attempt to modernize this beast began... but I digress. =) )
In this same editing process, users can define (and change) a list of valid values that can be stored in these user created fields (if the user wants to limit what can be in the field).
When the user changes the list of valid entries for a field, if they remove one of the valid values, they are allowed to choose a new "valid value" to map any rows that have this (now invalid) value in it, so that they now have a valid value again.
In looking through the old code, I noticed that it is extremely vulnerable to putting the system into an invalid state, because the changes mentioned above are not done within a transaction (so if someone else came along halfway through the process mentioned above and made their own changes... well, you can imagine the problems that might cause).
The problem is, I've been trying to get them to update under a single transaction, but whenever the code gets to the part where it changes the schema of that table, all of the other changes (updating values in rows, be it in the table where the schema changed or not... they can be completely unrelated tables even) made up to that point in the transaction appear to be silently dropped. I receive no error message indicating that they were dropped, and when I commit the transaction at the end no error is raised... but when I go to look in the tables that were supposed to be updated in the transaction, only the new columns are there. None of the non-schema changes made are saved.
Looking on the net for answers has, thus far, proved to be a waste of a couple hours... so I turn here for help. Has anyone ever tried to perform a transaction through ADO that both updates the schema of a table and updates rows in tables (be it that same table, or others)? Is it not allowed?
