I'm building a GUI that needs to be able to view a large amount of text
arranged in rows. Large being anywhere from a few hundred lines through a
few hundred thousand. I need a way to "cap" the max number of rows, so that
old rows are discarded in favor of new rows if the limit is reached.
My use case is very similar to that of the SQL Profiler GUI - I'm going to
be receiving a large amount of data from a server that I want to display....

Hi,
I have an application that's running fine on development servers (web
and database-sql server 2000). I'm updating a record through a third
party component but I don't think the component is the problem. What's
happening is that I'm updating fields that are part of view. I'm only
updating fields in one table of the view and this works fine in the
development environment.

I'm building my first major C# program and am try to use best practices
everywhere. So I've implemented the "Document/View Model" whereby:
- There's a Windows Form, which we'll call "formView"
- There's a Class, which we'll call "classDocument"
Thus, when an instance of each the form and the class are instantiated, they
each will hold the same data, albeit be independent of each other.
To keep the two in perfect sync with each other,...

Scenario:
I select data from a SQL Server View which links 3 tables, into a
single dataset table. I update some of those fields on a web form.
When I want to update the db, clearly I can't update via a View -
makes perfect sense.
But because I used a View, I can't use the CommandBuilder. I have to
specify my own Commands which will in some cases be huge and complex.
This seems crazy - what if I change the db structure? And because I...

dataGridView) that an update method is not added to the table adaptor. I
would like to update the b ase tables thorugh the view. How do i do this?

Dear All,
I am learning the document/view design. The document stores data and
provides GUI-independent operations upon it; while the views display
and manipulate the data.
Assume I have several objects to display in the view. And I can hide
some objects in the view.
My question is that: May I need to store the hide status of an object

Hi,
I have just installed visual studio 2005 professional edition (evaluation
version). However it will not allow me to view webforms in a website project
in design view. I can just see the HTML and the code behind, but no graphical
design view, which is pretty fundamental for development. I have .net
framework 2.0 service pack 1 installed. When I click on view designer it
appears to be locked, although there is no message. This happens on...

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,...

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...
