Hello all.
I have noticed that when I generate a strongly-typed dataset from an xml
schema that the DataTables that are generated have their constructors marked
as internal. What this means is when I try to instantiate one of the
strongly-typed tables from this dataset from a different assembly, I cannot.
Let me provide examples...
If I have a simple dataset like this:

Hello,
I am trying to create a strongly typed datatable/dataset from an untyped
dataset or datatable returned from a stored proc.
The structure of the table cannot be static since the results are
dynamic which means that I am right now creating the schema/structure of
the datatable from a datareader using reader.GetSchemaTable() and then
looping thru the reader to populate values.
Is there any other efficient way of achieving this?...

Hi,
I have a method, which opens a connection, creates an untyped datable, fills it and returns it back.
I have defined a typed datatable in my application as well. For some reasons, I have to call the above mentioned method to get data. Unfortunately, as it returns an untyped datatable, I can't assign my typed datatable variable this value (a base type can't be converted into a sub type automatically).
Without resorting to looping thru...

Assume you have a strongly typed collection of a class called Person. The
strongly typed collection implements IEnumerable so it can be databound to a
server control like a DataGrid. The Person class has several public
properties like FirstName, LastName, and Gender.
What steps would it take to allow the collection to be sorted in multiple
ways when bound to a DataGrid? In the past, I used the sort property of a
DataView containing a...

I would like to filter data in a typed datatable, while maintaining strong
type references.
The typed dataset/datatable is generated using vs2005 xsd.exe tool from a
xml schema definition file.
I don't understand how this is possible when its the dataview that is being
used to filter.
To filter I have to get the "defaultview" from the datatable, and the

Hi There!
I'm looking into Strongly Typed DataSets in the .NET Framework. I know it
can generated strongly typed tables as objects and column names as
properties.
However, one thing that I would like to know is if it wraps database Stored
Procedures as methods and functions? For instance, if I have a Stored
Procedure called SelectBestProduct in the Product table, would I be able to
call the Stored Procedure with

I have a strongly-typed DataTable I need to save as XML and later
reload it.
I thought that all I had to do was:
menuDataTable.WriteXml(filename,XmlWriteMode.WriteSchema);
And from another application do:
menuDataTable.ReadXml(filename);

Hi all,
This post is sort of tangentially related to my earlier posts on
configuration files for DLLs.
Does anyone know how to create typed DataSets using VS2005's new DataSet
designer, but with the ability to configure the connection string via a
config file? The designer seems to hard-code the connection string into the
dataset itself, which just can't be right.

Silly question maybe, but I've been doing the following for far too
long now:
public static DataTable myDataTable()
{
string sql = @"SELECT column1, column2, column3, column4
FROM myTable";
using (SqlConnection conn = new SqlConnection(websqlconn))
{
SqlCommand cmd = new SqlCommand(sql, conn);

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
