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...

I am facing problem in copying content of table from a untyped dataset into

Hello.
I am getting an InvalidCastException which has revealed yet more of my ignorance. I cant believe i
dont already know this and haven't encountered it before until now.
I am consuming a dataset from a webservice. I wrote both the server and client apps and the both use
the same middle teir. I fill a dataset on the server that has a relationship between two of the
tables inside. The relationship is between two strongly typed tables...

Hi All,
I'm New to VS.net. Trying to figure out this new dataset thingy.
Ok so I add a dataadapter with all the correct properties for a table. Then
generate the dataset. Now open the dataset and drag another table from the
server explorer, set up some relations there. Set up two grids, one a s a
parent one as a chgild. Fill the dataset, run the form
But my child grid never gets any records.
I then added another datadapter for the child...

My program needs to insert records into a strongly typed dataset. The records are passed as a String.
So far I have:

Hello
As a known issue, WCF does not allow to transfer typed DataSet. So I have to
copy all data from typed DataSet to untyped DataSet(same table names, column
names and row data). What is the most efficient way to do that? I tried to
remove DataTable from typed one then add to untyped one, but I tell me it is
forbidden to remove tables from typed DataSet.
Thanks

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....
Now, this would greatly impact the work of software developers. The idea...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
