My objective is quite simple. I want to display a JPG image and then on it
overlay a polygon. This polygon can be moved by a user. The even is trapped
on the mouse down event of the control. I can make the polygon move but the
screen flickers because I call invalidate() on the mouse down event. I did
do offscreen buffering but there is still flashing in the screen. Let me
explain what I am doing. in the pain even handler of the control I...

Hello.
I'm working with WinForm. It has 30 same user control, each with 4 buttons,
3 labels, 3 textboxes, 2 picture boxes and uses override onPaint to draw
gradient rectangle. Main form also has 2 panels with same gradient.
I'm trying to reduce drawing speed on form activation. But at the moment it
is too noticeable for each user control to be drawn.
Tried to use double buffering on main form and on each user control, looks
almost the...

I'm drawing graphics using the Graphics object one can grab in a Form's
Paint event. But I'm getting a weird thing happening...
These graphic shapes flicker (even if unchanged). UNLESS- I created a timer
and had the timer update a Label on the form with timer interval set to 10.
Now all the shapes I draw in the Paint event of the form draw WITHOUT
flicker!!!
What is updating a Label doing that is preventing flicker? Is it somehow...

picDocument is a picturebox
When I do picDocument.Invalidate() the box paints.
But if instead I do picDocument.Refresh() the box does not paint.
What does Refresh do. I guessed it did an Invalidate and an Update.
Can someone shed some light?

This is actually a follow on from yesterday's post about masking mouse
clicks in a user control.
The solution I have implemented - from Herfried - places a transparent
window over the entire user control, which then uses the various mouse
events to allow the user to drag the control without any clicks going
through to the buttons and dropdowns on the control below. All well and
good.
However, I am getting an unsightly flicker when I...

I've noticed some screen flicker when using Access 2003 under Vista
and I'm curious as to whether this is a bug or peculiar to my machine.
In design view, if I make changes to a form and then close the form, a
couple of seconds after I have OKed the save prompt the Database
Window that shows all my objects gives one flicker.
Once again, in design view if I change a property for a control in the
Properties box and then move the mouse...

Hi all,
I'm using a webbrowser control within an application for the UI and want
to hide the flicker and redraw when changing pages. Ideally I want to
render the new page to a seperate offscreen buffer then fade this over
the exisiting page. Can anyone recommend a good way to approach this?
thanks

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:

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,...
