I have a datagridview that takes data from a dataset from a table with an ID that is an identity specification number that is supposed to automatically give the next number. When I open a new line it should give me the next number but it doesn't. What am I missing?

I'm guessing that you won't get a number until the record is saved.

Datagridview is not an SQL table. Until the Record is Saved and the Grid is Refreshed you will not get an Identity number. If you made a gridview to generate the number , it does not mean the Database will do the same thing. If your Application is a multi-user application you will have problems e.g lets say a user assumes that the ID is the 10 and the user user does an insert somewhere and faster that the user that assumed it was 10 and the other user will get the identity of 10 and the assumer will get 11.
Hope it helps

Hi,
I do agree.. you can add an external col into your grid.

In some grids I get the right number, in one grid I get a minus number which saves ok afterwards but in the grid I'm working on now I don't get any number at all

Are you forgetting to close your connections, between operations? Or forgetting to close something that you have opened. A DataReader, or something like that.
Without seeing the code you are using, it is difficult for me to offer more than that. Others might be more helpful.

I am a newbie in programming and all the IT stuff,currently I am developing a webapplication to enhance my knowledge . I am using visual studio 2008,Sql server management studio 2005;in my application I am simply adding names and passwords in a table in Sql.
1)The application works fine when both Sql and published webappliaction on IIS are on same machine!
2)now I want the Sql database to be on other machine, and my published application on other system so that there are two different servers in LAN one the application server and other the database.
please help!
Thanks

So you have a working connection string already in your app, it will probably have "localhost" in the string. Change "localhost" to the remote server name.
You will probably need to change from integrated security (using your windows logon) to a SQL userid and password for the app to connect ans include them in the connection string.
A good research site is connectionstrings.com/[^]

the above solution will help my application to use a sql id and sql passsword fine
but what other changes(or configure) will I have to do in sql server itself?
Thanks

You will need to set up the SQL user with adequate permissions on your database. That's it.

Hi,
Actually when you remotely perform any SQL request (using OPENROWSET , BLOB type data) SQL server
need the AuC first. That you have the permission to perform this operation.

Hey,
I have this table:
JAN FEB MAR APR
--- --- --- ---
10 10 10 10
Suppose I'm in March now, how would I total the values of the two previous months (ie. JAN and FEB) to have 20
Please help.

Well, if that was what I wanted to do, I wouldn't start from there.
Has this design been forced on you, or are you free to choose your own?

It is forced on me, here's the big picture:
Jan Feb Mar Apr
--- --- --- ---
Budget 10 10 10 10
Actual 10 5 10 0
... 0 0 0 0
... 0 0 0 0
... 0 0 0 0

Sorry to be so long in replying.
I'm with Luc here, unless somebody else comes up with a viable solution I'd be investigating PIVOT. I have never used it, so I can't be of much help.
Good Luck!

Thanks Henry, Yes, it can be solved using pivot tables or the decode function but my problem is far more complicated to be solved by either of them alone!
Thanks for your time mate!

Is that a SQL table or a flatfile table such as Excel?

Hey Jerry,
It's a SQL Table, but dont worry, I've already found another way round, although it's not professional but it solves my problem. It was for a crystal report file and I figured out I can simply create a typed dataset with the exact names and data types of those of the generated query, generate the datatable fields from the invoking form using ado and set the datasource of the report to the dataset I just created.
Thank you for your time Jerry!

Hi,
the natural way a datatable grows is by adding rows, not columns. So a more natural design would have only two columns/fields, say "month" and "total", hence it would look like:
MONTH TOTAL
200901 10
200902 10
200903 10
200904 10
and now it becomes very easy to:
- add another month
- select some months and perform calculations on their data

Hey Luc,
Thanks but I'm kinda forced to this table structure:
Jan Feb Mar Apr
--- --- --- ---
Budget 10 10 10 10
Actual 10 5 10 0
... 0 0 0 0
... 0 0 0 0
... 0 0 0 0
Is there any way to do it with this structure??

Anything is possible, however I have never chosen such hard way of doing things, so I don't know any details.
FWIW: there is a PIVOT command that rotates a table.
