How can I develop a table that has a UTC Column that increments. For history I will have to add rows, how can I go about doing that and then anything in future, I want it to keep increasing.
View 1 RepliesI need to create a table with just 1 column containing times (starting from 4hrs) which increase in increments of 10 seconds for each row. So it needs to look something like this:
04hrs 00mins 00secs - 04hrs 00mins 09secs
04hrs 00mins 10secs - 04hrs 00mins 19secs
04hrs 00mins 20secs - 04hrs 00mins 29secs
.....
06hrs 59mins 50secs - 06hrs 59mins 59secs
This will obviously take a long long time to hard code so I'm looking to create it dynamically. Based on what i'm currently trying to learn I'd like to be able to do this using jquery or asp.net (vb) but anything will do as long as it works!

View 6 RepliesIs there a way to add a new column to the asp.net cache change notification (AspNet_SqlCacheTablesForChangeNotification)?
I wish I could do it so that generated trigger involve the new column. The minimum PollTime is 5 seconds (500 milliseconds) but this is not enough for us.
We have many customers working on the application and some times, some of them get logged out during operations.
We found that the problems come from the cache table (cacheId column).
I have created a web project using asp.net and visual web developer 2008. On my local project I created a new column in one of my MS SQL data tables and populated it with data. How would I create a sql script of the new column and data? I want to insert this into my live database on Godaddy?
View 1 RepliesI am quite new to LINQ, and I am stuck with this probably basic problem, but haven't been able to find a solution, so I thought I could ask here.
So, I have this repository where I put my functions for data accessing, and now I need to write a function to get all the applicants that have applied for this particular advertisement, and their values too. Now, the values are stored in a separate M:N table, where every row consists of the applicantID,advertisementID and value. I just wanna append the value to every applicant that I show, so that it would look like a Ranking List.
However, I do not seem to know how to select just the name column from the Applicant table, and just the Value column from the ApplicantValue table.
And there's this Iqueryable interface that further confuses me...
Here's my function to get the Applicants only:
[Code]....
Now, if I try to add to the definition of the type two columns, it says that it only messes with types, i.e. one type should be passed. So I figured I would do a ViewModel and then pass it, like this
[Code]....
and then in the function I have no idea how to pass the values:

I run a web site with VB.Net and Sql Server, at a web host (so I use one instance of their Sql Server db). I now get this nasty message when trying to access the web site: Column 'kryptotext' does not belong to table tabellen. I have seen this before (but with other columns mentioned), and when I spoke to the tech guys they said that the server gives up after five (or so) invalid requests. The old problems I had were due to the fact that I had used Application variables - at least the problems appeared when I added the variable and diappeared when I deleted them.
This time, I have done very little. I ran a new check when some items of a gridview were databound, and if a condition was ok, then a mail should be sent and an update take place in the db. For now, this will not be true, so the new code doesn't fire, and I have now reverted to the old code anyway. I got htis message this morning, and then it has worked the entire day without me changing the code at all, and now it stopped working again, so to me it seems as if it's either not my code's fault, or I somehow flood the db server with requests (but the web site is new so there are really no users yet). One more thing I have added: I imported the Net.Mail namespace to the baseclass I'm using for the aspx pages, but I can't believe that has anything to do with this.
I asked the tech guys again, and the server has been working the whole day. Here's the web site: [URL] I am able to connect to the admin part of the web site, so it's just the public web site itself that doesn't run. What should I do? Edit: Now, 30 minutes later, it works again. I haven't done anything, in fact I had dinner now.

I added a DateTime column to a table in my database through the Server Explorer. Because the team lead for this project wasn't savvy on nullable types, one of the requirements was that there be no null values in the database. This requires me to program all sorts of useless code into the system, but that's another story. My problem arises when assigning a default value to this column. I typed the following into the cell for the "Default Value or Binding":
1/1/1753 12:00:00 AM
When I went to inspect the content of the table, I found that all of the dates had been populated with:
1/1/1900 12:00:00 AM

Just iterates through the table and looking for any row with the boolean 'checkin' value is True, then it takes the 'id' value of that row and stores it into an array. Is there a way that I can access a another entry, and only that entry, in the table with the 'id' stored in the array?
Like if my data base contained and int, primarykey, `id` value, a boolean, `checkedin` value, and a `time` value, is there a way to access, lets say, the row with `id` equalling 3 and and the checkIn value from that row?
