Not that I'd actually do this... but knowing the answer would give me a bit
more understanding of the .NET Framework and the base class libraries -
specifically how things work in relation to my own custom classes or
libraries.
We could use any of the framework's classes - but lets take, for example,
the ListDictionary (System.Collections.Specialized.ListDictionary).
When solving some programming problem, I could (1) use the...

I've created a web form which fills a DataGrid with a DataSet generated from
the SqlDataAdapter.Fill method. The adapter's query takes about 30 seconds
to complete when I run it in the SQL Server Query Analyzer, but when I run
it from my web page I kept getting a TimeOut exception. So then, as an
experiment, I changed the way I created the adapter to the following:
SqlConnection conn = new SqlConnection(m_Conn);
SqlCommand sqlCommand =...

I have tried several different methods of getting a datagrid to fill with
information. Below is the code I'm now using. When viewed in the browser and
the text box filled with a parameter value (i.e. CA for Calif), the datagrids
header is displayed when the button is clicked, but no data is displayed.
I used SQL Profiler and can see that the query comes across with the
parameter, and if I take that query string and use it exactly in Query...

Is there a way to carry data that I have already read from the datagrid from
page to page?
I am looking at my Datagrid that I page through and when the user says get
the next page, I have to go to the database to get the next page. Is there
a way to use the dataset to allow us to read back and forth in it instead of
going back to the database to get it?
Thanks,

I understand that I can fill a datagrid with multiple queries, but I cannot
figure out how to fill a dataset with the same query but run against
multiple SQL servers, the query , table structure and username, password etc
will be exactly the same for each server, the only thing that will change is
the server name. Idealy I would like to get the server names from a seperate
dataset so there could be any number of servers, allthough in...

Hi I am somewhat confused, I am new at VB.net
I use XML data,

datatable that it would not update my dataset. So I created another...

I am trying to populate a Crystal Report from data in my DataGrid. The
reason for this is that I want the user to be able to change values
without updating the database, but still have their report reflect the
values they anticipate committing to see hypothetical totals of
columns from a set of records. These records are displaying properly
on my DataGrid but I'm not sure how to get Crystal Reports 10 to use
as its datasource the dataset...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
