hello.
it was fine to have system image list class/component in C++/Delphi
in old times. you can obtain just image index for file
with shell and your list/treeview already draw file icon.
but .net's imagelist is sealed completely and doesn't implement any
'imagelist' interface.
how could it possible to make system image list component so

This should be painfully simple but I have spent two days on it and I can't figure it out. I am NEW to vb.net, so please forgive my ignorance
I have a label that I assign an image to through an imagelist index
Label1.Image() = ImageList1.Images(3

Greetings and salutations! I am having a real issue with the VB.NET
TreeView control. I need to display an image (a.k.a. logo, picture,
etc) from a file as the treenode object. I can not seem to find a way
to do this in .NET. I have tried the DrawImageUnscaled and thought
that was the way to go, but I was wrong. If anyone has any
suggestions, please help! The code I have currently follows:

Hi,
I have a treeview which contains nodes of a class (classA) derived from
treenode.
These classA nodes may contain nodes of a class (ClassB) derived from
classA.
The form load populates a imagelist and calls a subroutine that assigns an
image to each node depending on its type.
If I expand a classA node, all is well. ie. I see the classA image on the
classA node and the classB image on the exposed classB node (which is always

Hi,
I am a little confused about associating an image w/ the VB.NET TreeView
Control. My specific requirement is that I want to associate an image w/ some
specific nodes in the TreeView only.
I coded a test project with a form with a TreeView and an ImageList control.

has anyone experienced this error before? I am occasionally getting this
error. I can't figure out what could possibly cause it. When the prog runs
thru the loop, the error could be thrown anytime. Sometimes it doesn't at all.

that it wants to be updated. But I timed it...

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:

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,...
