I'm working on a Windows forms/C# database application. My background is
6-7 years of VB 4 - 6, MS Access, VC++, mixed in with a lot of T-SQL and MS
SQL Server in general and some OOA/OOD.
Previously, I haven't been overly impressed with the capabilities of the
various "graphical" data access tools that have been provided with VB etc.
Though deceptively simple to get started with, IMHO they haven't provided
the necessary flexibility...

I am building an ASP.NET page that displays a recordset with a Delete
statement enabled (this all works fine). I want to Insert the current
row *that is going to be deleted* into another table, before the
original data is deleted.
I am trying to use the RowDeleting method to call an Update or Insert

I created a VB.Net 1.1 application that iterates through all the tables
in any basic Access 2000 database passed to it and generates the same
table structure in a SQL Server Express database. The structure is
created fine (with minor data conversions from one to the other, e.g.
yes/no --> bit, memo --> text, etc). My problem now is transferring the
data over from Access to SQL Server. I thought it would be a fairly
straight forward...

In the following code I retrieve data from a stored procedure that
returns multiple resultsets (the results of the stored procedure have
been stored in a datareader called reader). On each iteration a tab
page is added to a tab control and a datagridview is created on that
the tab page. In the first iteration I can set all the values with no
problems, however on the next iteration, even though there is
definitely data in the data source,...

If I run the stored proc in the Query Analyzer this works and I get the
expected result set back. However when I run it in my application I get
a results set of one row but when I try to access the values I get
"Invalid attempt to read when no data is present".
private void GetLotIDPriorityFromLot(string aLotDesc, out int aLotID,
out DateTime aPriorityDate)

SqlConnection Conn;

how do you resolve this problem?
i have a public procedure in my DataAccessLayer that gets a SqlDataReader
how do i close the reader from inside the DataAccessLayer if I'm returning
the reader to get bound to my GridView? Any code after my return will be
unreachable.

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,...
