Problem:
I am fetching data from the database, storing it in a
dataSet, and binding it with a Data Grid. The DataGrid
controls allows sorting. The problem is that when the data
is sorted on one of the columns in the Data Grid, and I
then try to retrieve the selected row using
the "SelectedRowIndex", I get the row as per the original
order of data.
Eg: If the order of rows is: C - A - B, which after
sorting becomes A - B - C. Now, if I...

I'm having the hardest time doing the simplest thing.
I have a DataGrid bound to a table in a master detail DataRelation within a
DataSet
relTaskActivities = new DataRelation("TaskActivities", parentCol, childCol);
dsTaskActivities.Relations.Add(relTaskActivities);
dgActivity.SetDataBinding(dsTaskActivities, "Tasks.TaskActivities");
This works fine. I have a properly behaving master detail relationship.

I have created a dataset with two tables and an insert command, I need to be
able to retreive the Key Identity after inserting into table "A" for use in
table "B".
Should I use ExecuteScalar() or is there a better solution?
Thanks, Justin.

Hello All,
Was wondering if we could retrieve the index of a particular row from a
dataset's table based on the filter criteria for the row?
For example, I have 4 rows in my datatable which is inside a dataset. One of
the columns is "ID" field. If I want to retrieve the row index of a row with
ID = 10, is there any API which I could use in .NET framework.
I am using a kinda beginners code to compare each and every row's ID in a

Hi All:
Here´s a very simple question:
I have created a datatable inside a dataset, and subsequently selected
a particular row using certain criteria. How do get the index number of
that particular row? There doesn´t seem to be property like
"mydatable.currentlyselectedrowindex" or "myrow.indexnumber".
Any suggestions will be highly appreciated.

New to .net....sorry if this seems repetitive
I have a dataset ordered by date (SQLDataAdapter SelectCommand uses
Order By) and want to find a record by a UniqueID(Identity Column).
Then I want to change the position (BindingContext) in the dataset to
have all my bound controls reflect the data in the found record - and
the related records/tables.
Problem is, it appears it can't be done....

Ok, I can't believe what I am seeing. I am sure I do this other places with
no problems, but I sure can't here.
I have some code that is indexing into the ItemArray in a DataSet's DataRow.
I basically want to change the value of the data stored at a particular
index in the ItemArray. Ideally, I would like for my code to look like this
(pay attention to the index of ItemArray):
row.ItemArray =
itemArray.ToString().Substring(3);

Hi, I recently wrote an ASP.Net web application in VS2005 and published
(using VS2005 Publish feature) it to a relatively clean machine with
ASP.Net 2.0 and MDAC 2.8 installed on it. However, when I try to create
my SQL connection in the code-behind, I get the following error. I
tried to register the DLL using regsvr32 but that errored out saying,
"dllregisterserver entry point was not found". Any ideas?

Hi ALL,
I wonder if anyone has been using n-tier to bind to a GridView control by
using the ObjectDataSource. This is our first OOP web application, and we
have no tables. Right now we are simply working with objects in memory.
So, it appears as though Microsoft requires that our datamapper classes
reside inside a folder called "App_Code", and NO WHERE ELSE.
So, has anyone successfully been able to place their datamappers in a...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
