Hi
Could someone clarify for me the method parameter passing
concept?
As I understand it, if you pass a variable without
the "ref" syntax then it gets passed as a copy.
If you pass a variable with the "ref" syntax then it gets
passed as a reference to the object and any changes to

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...

Hi,
In my application I get lots of different sorts of information from
databases. As such, a lot of information is stored in DataSets and DataTable
objects.
Up until now, I have been passing around chunks of data in
DataTables/DataSets, simply because that was the format that they were in
when the data was taken from the database. Now, I know this maybe a pretty
silly question with a standard "it depends" answer, but I'm going to...

Hi,
I have to write an application which extensively uses an SQL Database.
For a simple example say I have the following tables with the
appropriate fields.
1. Company (ID, Name, AddresseInfoID)
2. AddresseInfo (ID, Street, City, Zip)
(Those two obviously have a relationship)

the enterprise is going to eventually convert the existing ASP Classic

until that time, development has already begun for a C# library of
business objects. for the most part, the ASP Classic can make use of
the C# business objects without problem, because they were compiled and

however i have just reached a point of uncertainty: sets of data.

Hi all,
I am hoping that someone with some experience developing nTier apps can give

What is the best way to pass a data set between objects? I have a custom
control which will depend on a dataset (kind of like a bound contorl, but im
handleing it differently) is it best to pass as a public variable or a
property? since a property only retrieves By value, and not by reference,
when you send a data set in does it make a copy of it for that object? or
just pass a reference similar to what an array would do in C++. What i need...

Hi all,
I'm currently designing an n-tier application and have some doubts about my
design.
I have created a Data Access layer which connects to the database (SQL
Server) and performs Select, update, delete and inserts. I use dataset
objects to pass data to and from the DAL.
In my GUI (windows forms), I use databinding to bind controls to a datatable

I was under the assumption that if you pass an object as a param to a method
and inside that method this object is changed, the object will stay changed
when returned from the method because the object is a reference type?
my code is not proving that. I have a web project i created from a web
service that is my object:

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,...
