simple thing,u can use datarelation class in the dataset object.

/*code*/

ds.relations.add("relationname",ds.tables[0].columns[id],ds.tables[1].columns[id])

/* use foreach statement to retrieve the records.......*/

use getchildrows () inside the loop.....

There is a data relation defined in the DataSet already (created using the designer in VC# Express 2005). What I'm trying to achieve is essentially filling in some default values in the child row based on the data stored in the parent row.

At the moment I've got an event handler for the DataGridView.DefaultValuesNeeded event, this is working well so far but that's because the default values (although dynamic) are simple, e.g. one of them is the current date so I've just put it a:

e.Row.Cells["QuotationsDate"].Value = DateTime.Now;

But looking up a value from the parent table is more difficult since e.Row.DataBoundItem is not yet initialized, presumably this is called before the row is initialized.

Is the only option to modify the DataSet.Designer.cs file so that it provides the default values. This would work (I think) but I don't know what VS would do if I happened to load the designer, it'd probably overwrite the changes. Still it may be the only solution.

Any thoughts?

Anybody know how to script out the data in SQL 2005? i.e. I want all the data in a table to come out as INSERT statements.

Or do I have to write the code myself?

I havn't come across anything (but havn't used SQL 2005 that much) but my guess is that you will have to write the code yourself.

Hi guys and gals!

I am using C# (VS2003.NET) to create my PPC application and SQL CE as my database back end. I have a little app that captures information on my mobile device. How can I sync my PPC data with a SQL Server 2005 Express DB on my server?

Any help will be GREATLY appreciated.

Kind greetings

SQL Server CE has built-in replication capabilities. These use IIS as a front-end, and you need to install the appropriate components for your version of SQL Server. See here[^] for information on these components. I don't know if SQL Server CE 2.0 is compatible with SQL Server 2005 Express.

The second method is to use the SqlClient namespace to connect directly to your SQL Server, and use queries against the SQL Server 2005 database to manually synchronise your SQL Server CE database. This is more effort than the first option but doesn't require any changes to SQL Server. You will also need to make your SQL Server available over whatever communications method you're using; you may not be comfortable exposing your SQL Server to the internet. I wouldn't be.

Both of these options tie you into using SQL Server on the host, which you'll have to judge for yourself whether that's a problem. The third option is to write your synchronisation mechanism yourself. You might consider using Web Services as the communication protocol.

In your Select statement try using a range. For example:

<br />
Dim query as String<br />
query = "SELECT * FROM [" + sheet + "$" + range + "]"<br />

You may also have to add TableMappings

Another thing I want to mention after being burned by OLE DB and Excel. Even though you have IMEX=1 set, don't be surprised if the data fill contains some unexpected nulls. This happens because the underlying ISAM driver for Excel uses the first 8 cells of a column by default to determine the type. If you are dealing with spreadsheets from other people, chances are they are not 100% clean.

Fear not, all you need to do is edit the Registry and change a setting:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\4.0\Engines\Excel

TypeGuessRows should be set to a value appropriate for determining the data type of your column. You can specify 0 and it will scan 16,000 rows which is probably overkill in most cases. This is an intertive process to get to the point where you have an acceptable value and clean results. Once you finish the tuning remember to add the registry setting to your setup program

Good Luck

Resetting the auto-increment

Hi,

I have a members table, and the primary key ID is of type int, which has been setup to automatically increment the ID by 1 when a new member has been entered. I have added a lot of members while testing, but when I go live with the site then I would like to reset the auto-incrementer so that when a new member is added it starts back at 1 again. How do I do this?

I hope someone can help!!

Regards,

How to setup a column to auto-increment

Mundo Cani8-Mar-06 8:07

Hello,

I have an identity column that is set up to auto-increment via the "Identity Increment" property for the column. This is working fine.

However, I have another column that I'm calling "Sequence". This is not an identity column, it just specifies the position of each record which is subject to change. I want to set up the column to auto-increment so I don't have to manually enter the Sequence number for each record I add. Is there a way to set up a column to auto-increment without making the column an Identity column, and still allowing me to manually change the Sequence numbers later if I want?

BTW: I'm adding data to the table in Microsoft SQL Server Management Studio.

Thanks!

Ian

objCol.AutoIncrementStep = 1;
objCol.ColumnName = "ID";

You caqn not have more that one identity column per table. The way to handle what you are attempting may be to insert the new record, get the identity using the SCOPE_IDENTITY() function then updating the record with that value

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
