Hi all
I have an ARGB value for a Colour (Eg. -65536. The value was retrieved by
using the Color.ToArgb method), is there any way that I can create a
System.Drawing.Image or a System.Drawing.Bitmap from that value?
Regards,
Steve

Hi All,
In my application I am allowing the user to draw a line. But when the user
clicks the start point and starts moving the mouse there is a series of line
generated. When the mouse is up the final line is drawn.
How to avoid the series of lines being generated during mouse move event?
How to get the rubberband effect when the user moves the mouse?
I tried using the ControlPaint.Reversible line but this does not help

I have an Windows application that displays lots of different colored lines in a Panel by using the Graphics.DrawLine method. The location and length of each line comes from a database query that takes two minutes to complete.
I am using the Panel's Paint event to call my drawing method, which accepts PaintEventArgs as a parameter. The problem is that every time the Window is moved or hidden, it needs to be repainted, which takes a long time...

In .NET Windows forms I can create a metafile using this code:
Graphics grph = aControl.CreateGraphics();
IntPtr ipHDC = grph.GetHdc();
Metafile mf = new Metafile(aImgFilePath, ipHDC, EmfType.EmfOnly);
grph.ReleaseHdc(ipHDC);
grph.Dispose();
grph = Graphics.FromImage(mf);
grph.DrawRectangle(aPen, 10, 10, 100, 120);
grph.Dispose();

I need to create a Drawing.Bitmap from an array of integer
values. My current technique creates a bitmap that
eventually becomes corrupt (i.e., the bitmap's pixels
change to a different color after a while). Can somebody
please tell me what I'm doing wrong? Here is a sample:
Public Shared Function CreateBitmapFromArray( _
ByVal width As Integer, _
ByVal height As Integer, _
ByVal pixelFormat As Drawing.Imaging.PixelFormat, _

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

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,...
