i,
I have trying to code a small console app that will
allow a user to select a window and then create a
screen capture of the window. I haven't been able to
figure out how to do the screen capture part. The
code is as follows, the commented out lines at the end
are things I have tried, but don't work. Whenever I
try to create a compatibe Bitmap or DC it comes back
with an error as
win32ui: CreateCompatibleDC failed

Greetings.
I encountered a wield problem when grabing screen images.
Sometimes in some computers I can capture the screen, but other times not
so.
In some computer I cannot capture the screen image, but when I change its
color bits, say from 32bits to 24 or 16bits, the program can capture the
image.
Can anyone kindly examine my following code, and point out the flaw:

Hi all,
This may be a newbie question, but I can't find the answer anywhere.
I want to make a capture of the screen, or a part of the screen, that
contains the main portion of the form.
Detecting the screen that contain the main portion of the form is pretty
straight forward, but how do I capture what I need in an Image object?
Another thing, how do you make the program move the mouse pointer and
simulate clicks?
Best regards

I have seen some examples of how to capture a color from a point on screen
using C#, but haven't come across anything with VB.NET. Is this possible
under VB.NET? I know that I will need to use the GetPixel API in order to
do this.
Essentially, I would like to be able to move the mouse around the screen,
and wherever the left button is clicked, I would like to store the color
value of the point where the cursor is located. If possible,...

I have one here that I cannot find anything on in my searching.
I am implementing a screen capture functionality into my Visual Basic
..NET application.
The code I am using calls the bitblt function in gdi32.dll to achieve
its magic as follows:

I need to take a screen shot of the computer screen.
I am trying to use PIL and I saw there is ImageGrab...however it only
works on Windows. Is there a platform-independent ability to work
around this?
thanks

I use this code to capture a screen in a regular VB 2005 windows app.
It works great! I found the code in google. But when I create a windows
service it does not capture the screen. It only captures a blank
graphic. Does anyone know why it will not capture the current screen?
Is something not available when running as a service? Thanks!!!

I'm using ASP.Net web services to provide the logic required for a
Flash based prototype. The Flash and the ASP .Net run together on the

IageGrab, but in the free version it only works under Windows. Is
there any package to capture the screen on Linux?
Thnx

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...

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,...
