For all you seasoned VB programmers this is going to be a no brainer.
However, as a C programmer learning VB I'm having trouble getting my
arms around the event-driven nature of VB.
Suppose I have a form with a single command button (cmdPush).
The form's code (including the cmdPush_Click() sub is between the
dashed lines.

Hi al
I am trying the following
On a base form I open a new form with a treeview
On the base form, there are two buttons
Depending on the selection in the treeview on the new form, I like to enable or disable buttons on the base form
I do not like to declare and open forms as static. Would be nice if I can handl
this somehow with a delegates where I can pass parameters..

I would like to disable a button on the form if the user is not authorized to
use it.
I've created a custom button and would like for each button to know if it
should be enabled or disabled based on another class that would contain the
users authority levels.
I know I can use the on form load event, but I rather test to see if the
user has access to the button during the buttons OnPaint event? If they
don't have access, I'd like to...

I have not been able to figure out how to catch the click event from a
button that is added dynamically to a table. In priciple the process is as
follows:
When I first create the page I analyse data and if appropriate:
- add one or more row to a table in the webform
- add cells to the rows
- add a button (myButton) where the user can change some settings.
- enable/disable some other buttons to the form
This is all done in a function...

Hi,
I was wondering if it were possible to add some code that would proceed
and/or follow the execution of each each event in the form and/or
application? The code would be the same no matter which event is being
called, so it would be ideal be able to write it only once, or at least
once for each form as opposed to writing it into each event in the
application.
In my situation, I need to deactivate a particular global class object

Hello,
I have a standard asp:DataGrid called CasesGrid that I wish to write my

Hey Guys,
I'm experiencing some really odd behavior from the simple onclick event attached to one of my buttons.
I have a user control, with three buttons Save, Edit and Create. They enable different asp.net controls and that's all working fine. However when I click my save button after I have edited some data, the new data is not loaded in with the onclick event of the save button.
So to speak, it just reposts all the old values and stores...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. 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...
