Hi, I'm a VB.Net developer and cannot find a way to create a bipmap from a
pointer...
My application does video rendering using Windows media encoder (that's out
of the content of this message). Using a "DataView" object I can attach a
"video viewer" to about every control in a Form, using a "integer reference"
to attach the viewer object to the control you want to use as a viewer.
Question: is there any way to use the "lpreviewStream " integer to generate
a bitmap using BitBlt, new Bitmap(...) or some other way? (I'm trying to get
screen shots of the video on screen)
Here's part of the code, when I create the viewer and attach it to a
pictureBox:
(thanks for any clue)
-->SrcVid is the Encoder object that gives you the video from
a device
DVColl_Preview = SrcVid.PreviewC ollection
'Create WMEncDataView object
Preview = New WMEncDataView
'Add the WMEncDataView objects to the collection.
lpreviewStream = DVColl_Preview. Add(Preview)
'// Start the encoding process.
Encoder.Prepare ToEncode(True)
Encoder.Start()
'// Display the preview in a pictureBox named pic1
Preview.SetView Properties(lpre viewStream, pic1.Handle.ToI nt32)
Preview.StartVi ew(lpreviewStre am)
Regards,
Victor

Hello!
My goal is to develop a program that opens a bitmap, copies its pixels
to an ArrayList in order to perform some complex calculations (edge
detection, Hough transform etc.), and save resulting image back in some
other bitmap.
It works pretty fast, except for stages of coping pixels between bitmap
(object of type Bitmap) and the ArrayList. I'm using the trivial

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,...
