I am trying to make a list, separated by a comma, of entries from a single column in a SQL database. I have been spending the last several days searching for a way to do this, but every thing I found either didn't work, or wasn't exactly what I was looking for.
The query will pull all the email address that are not null. What I need to know is how to take the result of that query and make it look like this:
email0@address.com, email1@address.com, email2@address.com, etc, etc, ...
I feel like I should know this, but for the life of me, I can't remember nor can I find it in any of the textbooks I have.
I am using Visual Basic 2010 and SQL Server 2005. I also have access to Visual Basic 2005 if needed.

I'm trying to create a "LOTTO" number picker, but I don't want to have more than one TextBox. And I also don't want duplicates in that single textbox. The program randomly picks six numbers from 1 to 30 (Sorry I don't have the code at the moment).
My code runs fine, but I keep getting duplicates in the textbox. (I'll update as soon I have the code.)

I'd like to create a standard AutocompleteTextBox that works with a timer, such that there is only one BackgroundWorker working on searching - if the user entered a few more keystrokes, but the old search is still running - that search shall be canceled gracefuly (via CancelAsync), and as soon as its canceled the new search will begin.

I'd like to see how others might handle this scenario and perhaps provide some comments on this particular solution for handling null values. I have run into a situation where my application requires data from an ancillary source that cannot be altered/changed, which of course means dealing with poor database architecture and implementation! In this case, my app is running into errors when attempting to set some form controls (textbox) to values from a single ADO.NET DataRow. Perhaps I should be handling this when attempting to set the controls? Not sure, but here is the current way this is done:

The output I am looking for is like this:

I have Visual Basics 2008 express and I tried to make a autotyper, so this is my
Button1: Timer1.Start
Timer1: Timer2.Start
Timer2: SendKeys.Send(Textbox.text)
Button2: Timer2.Stop
So it was my first try ever with VB and it kind of worked... Only 2 problems;
1. Button 2 doesn't really work, I have to click it really many times, then go to a different window, then click it really many times again, in the meantime it keeps on spamming
2. How do I make my autotyper press enter every single time after the textbox message was typed?

I have a project where I want to have checked arithmetic by default, except for one performance sensitive spot. Unfortunately, VB.Net doesn't have an 'unchecked' block.Ideally the framework would have some sort of integer type with explicitly unchecked arithmetic, but I didn't find anything like that. I did find that expression trees have binary expressions for unchecked operations, but the delegate overhead cancels out the unchecked advantage (and then some).
Currently I'm converting the inputs to UInt64/Int64 before doing the arithmetic, then converting back (with a bitwise And to ensure in-range). It's about 50% slower than unchecked arithmetic (according to profiling).
Moving the arithmetic-sensitive part to a project with unchecked arithmetic might work, but it seems like overkill to give it an assembly all to itself.

The value of d3 is not coming to 301006308001004.5 but it is getting rounded off. Is there a way to fix this. When I use currency data type, the issue looks solved. However currency cannot hold a larger decimal number. the value of d2 can have more decimal value like 0.343324532553 .

I have a problem with the code I will be posting down below, when I use the logout button & then I proceed to re-join & the server gets taken down the client crashes/closes, debug mode shows errors in general as the debug session closes out but it doesn't go to any lines of code or anything for me to find where the problem is happening at.
Now I know this isn't a server issue for sure, no bugs show up in the servers coding program at all & it shouldn't take the servers help for a client to disconnect properly between my app being closed & them using the logout button. It only bugs when the server goes down & only after having used the logout button since you've opened the application..
A first chance exception of type 'System.InvalidOperationException' occurred in System.Windows.Forms.dll

I have two projects.. in one, the SqlParameter does this and it handles single quotes fine, in another, it does not and I'm at a loss why (I even copied and pasted the code):
