The example for updating an non-strong typed dataset in the resource kit
shows:
dsNorthwind.Tab les("ProductsDS ").Rows(lstResu lts.SelectedInd ex)("ProductNam e
") = ProductName & " - Updated"
My code is something like this:
for each srcrow in myds.table(0)
.. do some stuff ..
myds.table(0).r ows(rownumber)( "fieldname" ) = 1 <== Question is here
next
I don't have a SelectedIndex to use as a row number. How do I address the
current row? Rows does not have an "itemindex" , "currentrow ", etc.
property. What do I do?

You are already doing a for each, with a 'srcrow' variable, so just use that
to set the field.
If you want to index by number, you have to use a regular for loop, and use
the for variable to index in.

Marina, so you're saying that the following does update the dataset?
srcrow("fieldna me") = 1
I did try that, so I must have an issue with the update method then.
Thanks.

Hi Jeremy, Marina, so you're saying that the following does update the dataset?

Yes
If you want to test it, set a
messagebox.show (scrow("fieldna me").tostring ) behind it.
Just to attent you, that "fieldname" is a pseudo?

In a .Net solution that has a DAL, Class and Business logic.

updating instead of inserted?

Hi
I'm hoping somebody can help me with the following problem that has occurred
to me.
Suppose I have two tables in an SQL Server database. Let's call these tables
A and B. Assume that A has two fields: a primary key and another holding a
string. In table B there are three fields: a primary key, a foreign key
(which links to the primary key in A) and other field holding a string.

I'm not sure what exactly is going wrong here. I'm writing an application that retreives a table from a database (tbl_internalfaults) and updates it. (Actually, just the status column will need updating with 'CLOSED' where necessary.)
