Dear ladies and gentlemen:
How to access all the pixels of a bitmap with C#? I am working with
Delphi before. In Delphi, you can use TBitmap.Scanline property to access
all the pixels of a bitmap object. How to do this with C#? Any hints? Thank
you very much.
Best regards.

Hey. I've got a color photo in a simple unsigned charRGB array. The photo
does not exist on disk. I want to display the photo in my window.
The application I am working in (not my choice) demands that I draw into the
display by first creating a Bitmap, and then drawing into a DisplayContext
using BitBlt(). The pseudocode looks something like:
// Create an empty bitmap:
HDC hScreen = GetDC (0);
pHandle = CreateCompatibleBitmap...

I've been looking on the Internet for a way to convert a DIB to a Bitmap
without success.
Now I'm wondering if that is the approach I should be taking.
All I want to do is display the DIB or draw it into a Bitmap.
Is there a graphics method that can help?

I trying to learn what a Bitmap is. Not a Managed Bitmap Object but one
that, for example, comes from the clipboard with CF_BITMAP.
I'm guessing that a CompatableBitmap is an array of indices that point to
the colors in a Palette of the display driver.
So if I get a bitmap via CF_BITMAP I need to also get a Palette off the
clipboard and realize it then display the bitmap.
I believe "Realize it" means to put it into the display driver.

2005, but after installing Visual Studio 2008 then opening the solution as a
..net 2.0 project, I get an error on the 'bmpOut.Palette = imageFile.Palette'

Anyone come across this or suggest a reason for the error?

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,...
