Does anyone know how to change the the GDI+ coordinate system like you used
to be able to do in VB6 with the picturebox.scale method. The
picturebox.scale method took an x,y point defining the upper left corner and
a second x,y point defining the lower right corner.
In VB6 the 0,0 location was the upper left like in GDI+, but I could at
least reset it so I could use it with lat/lons. Basically all I want to do
is be able to use the...

I am creating a control that will take an image and make parts of it
transparent, this is done by creating and then applying a region to the
control. The control inherits from picturebox and works fine when loading
the image into the control, the problem that I am having now is, once the
control is loaded and the image is displayed, if the user resizes...

I do the following where sss is a string equal to a filename.
PictureBox.Image = = New Bitmap(sss)
It occurred to me that the file will be locked until the picturebox is
disposed at the program end.
Would it make more sense to use DrawImage.
I mean, is that what programmers typically do?

Hello Newsgroup,
I try to resize and move a picturebox. However, after each operation
the picture box is being redrawn. This causes flickering. Is it
possible to suppress the first redraw and draw both operations at once
after they have been completed?
I have tried overriding OnPaint, OnBackgroundErase, etc. Double
Buffering, AllPaintingInWmPaint, etc. has been set to true.
No success so far.
Now I'm trying to catch Windows Messages like...

Hi there,
I am currently writing an application where one inspects images and
annotates certain features. Thus, one has to zoom in (4x) and pan around. The
features are marked with little red rectangles.The images are 2048x2048
pixels.
It seems that I can find no efficient way to implement both zooming and
panning.
At present I have a panel with autoscroll set to true inside which there is

I am currently creating a little photo application. In this application the user is able to zoom in the image and after zooming panning around inside the zoomed image with the mouse. The strange thing is that the first zoom is really slow, and so is the first panning. So if you zoom into an image it will first take some time, and when trying to pan the image around things will be really choppy.
However if i zoom into the image even more, and...

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,...
