I wish to build a framework for our developers that will include a singleton
pattern.
But it can not be a base class because it has a private constructor and
therefore can be inherit.
I thought maybe a Template can be use for that, but C# does not support
Templates (will be C# generics in mid 2005).
Does anyone have a solution on how the singleton pattern can be written, in
C#, as a framework/ infrastructure class, so users can use this...

In his book "Patterns of Enterprise Application Architecture", Martin
Fowler says that using the Table Module pattern to model the domain
logic precludes the use of inheritance and GoF style OO design
patterns. I'm in the midst of helping to write my first 3-tiered
architecture using the Table Module pattern and am having trouble
understanding why that would be the case.
In the example he gives of the Domain Model pattern (the fully...

Hello All,
I am designing a class based on singleton pattern. Inside this class I have
multiple instance methods. My question is since there will be only one
instance of this class at any instance of time in the whole application there
is no use in having these methods as instance methods I can as well have
static methods....correct?
If I leave these methods as instance methods would they have any wrong
impact on my application?

I could do with something similiar, can you tell me if you think this
would work for me, and if there's any advantage in working with

this way than how I currently am.
At the moment i'm using the treenodes and each treenode needs a unique
entry into my rich text box. After sitting at home with MSDN i've

Hi guys.
I am preparing the rewriting of an huge existing application in VB6. This
software is a mess of 10 years of patchs and new functionalities added
randomly, and didn't have any logical or oriented-object background.
This software is used by many differents persons, and there is a LOT of
functionalities that exists only for one or two of them. So, I want to use a
plugin-based system. That's it for the background.

Hello,
I am looking for a good pattern. I have a rather large software app
that makes use of a service manager for its many services...
configuration, colors, data lookup, units, etc. Up until now the
service manager has been a singleton and anyone who wants access to a
service just asks the singleton.
Now we have a new requirement... run multiple instances of the
software in the same application space with different configurations.

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,...
