Sample in C# and VB.NET are OK.
I have a table "People" with the following columns:
-FullName (nvarchar not null)
-DOB (datetime null)
I want to write a LINQ to SQL to group the people by age, like following result:
Age 19: 4 ppl
Age 20: 5 ppl
Age 21: 6 ppl
Here's my try:
Dim query = From ppl In db.People _
Select New With {.Age = DateTime.Now.Year - CDate(ppl.DOB).Year, .CountAge = ppl.Count}
Notice that there are no DOB record for some people in the tables, so these shall not be included. The DOB column has record like this 1982-10-24 10:12:45 AM because it's a DateTime column.

How can I let people download my software that i have made. the furthest I have got is that people can go to google docs and download the .exe file. But they have to choose a place to save the file and create a desktop shortcut themselves. How do I do this: Can I use SharePoint?

I'm working on a VB.NET application for disabled people which uses the WebBrowser control to capture the HTML content from an webpage (just to present, after some code treatment, in a textbox) and trying to solve the following three problems:
1) I'm using the WebBrowser control just to load a web page, but some pages provide a refresh after some minutes. Is it possible to avoid/disable the WebBrowser refresh (important: I need to keep the WebBrowser instance alive, so I can simply dispose it) or I'll have to rewrite my application to use WebClient control instead? (solution that will be provide much more work in my case).
2) The DocumentCompleted event, that takes the HTML content and shows in the textbox, is called several times for some pages (like www.uol.com.br) and obviously beginning to execute the code on my sub method several times too. A friends of mine tell me that maybe it can be solved "setting the WebBrowser for HTTP 1.0 to avoid the load from Ajax content". Is there anyone who knows how to do it or simply knows a way/event more precise?
3) Is it possible to take the HTML content and convert the charset "on the fly"? If not, anyone knows an URL with a sample code?

I've got an app that manages estimates on jobs. When an estimate is loaded an e-mail has to go out to a list of people (different list for each job) that they should log in and approve the estimate. Least visible to the user making the estimate. Our should I research SQL mail and see if the sql box can handle it without the app user even knowing it?

first wanna say, awesome forum here wish i'd found it sooner so basically im trying to create a tool for my group (6 people) that tracks tickets they work, basically we work jobs by ticket request and im trying to create a tool/program where they can enter:the ticket number if they completed,pending etc and notes of the job i figured it was gonna be easy, do a simple GUI that saves the info to a excel sheet or a access DB file.
that is basically how it looks. what im trying to figure out and hoping to get some help on is what is the best way to go about this? would a access DB work out better? (since i am hoping to expand it later like add a auto date/time function etc)how do i get it so when i hit the "submit" button it copies the fields and puts them into the DB file?

I am trying to make a program that can calculate the percentage of people passing an exam. There are buttons for each letter grade, and working label counters for each time you press a button. Each button looks like this, except replace the letter with the appropriate one.
Private Sub btnA_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnA.Click
Static intA As Integer = 0
intA = intA + 1
lblA.Text = intA
lblPercent.Text = (lblA.Text + lblB.Text + lblC.Text + lblD.Text) / (lblA.Text + lblB.Text + lblC.Text + lblD.Text + lblF.Text)
End Sub
My problem is that the percent does not equal what I get when I put the exact same numbers into a calculator.

I want to make a program that will track Do Not Rent (DNR) People.I'm a intremediate vb6 programmer and have not coded in a long time.I do have and wanting to do this on VS2008 professional in VB2008.I did a simular program from a vb6 book about 12 years ago. it was a address book that i changed a little to add some things I needed it to keep track of, and it saved everything in a text file.I want to know what the pros and cons are for using a text file? xml file? or a data base?the data i be keeping track of will be vital statistics as name, state id number, id type, ect. and a picture of the id from a scanner or import from a .png, .jpg, or tiff image.If i use a data base file either Access 2007, MySQL, or SQL 2005/2008 file, do i need to have Office, MySQL, SQL 2005/2008 programs installed on the the computer im doing the programming on? do i need to have the above programs installed on the target computer?i do not think a txt file will work for me because of the picture i want to keep with the data not seperatly. So to make it a little more clear I want to be able to add, append/update, not to be able to delete a record, and be able to search the file for a record.I want to be able to navigate the records or file with first, previous, next, and last. each record will be showed seperatly.I would like to have a STATUS (lol thingy) that only my wife or I can change but let my employees be able to enter the rest of the information on there own. the STATUS Levels will be like 1st warning, 2nd warning, 3rd warning, DNR, and Rentable at our discression. I want it to only allow changes to status if they have the proper password. so i do not know if this also elimates txt files or xml files as an option.and when the wife, my employees or I make an entry I wanted it to add the time and date with the comments we entered in with the initials of the person whom entered the data. so i was thinking i will need to have security levels in my program and give each person a password so the program can fill out most small data itself.
if i do decide to use a database file to store the data, picture, and employee information can it be done with 1 table, or should i try to seperate the data in seperate tables? should i use one to one or one to many? I do not think one to many would be the best solution? it been like 12 years since I did any database programming in school and it was dBase3. If u think it be best to use multiple tables could u give me an example as to how to seperate the data.The client info would be like a address book with a picture and a comment box that will automatically add a date/timestamp and the users initials with a space between every updated or appended entry., and the employees would have there login in name and password, and initials.I was thinking of making a wizard to enter the data in for both employees and the DNR's as for people changing the date on the computer and entering info so to make it look they entered data on an earlier date I was thinking of having it log onto the internet time server and setting the date/time of the computer in the background as it loads up.
