PLease Help me it will be deeply appreciated!!
Dim g As Graphics = Me.PictureBox3. CreateGraphics( )
g.Clear(Me.Pict ureBox3.BackCol or)
Dim curImage As Image = Drawing.Image.F romFile(Applica tion.StartupPat h + "\Resources\Sou th1.png")
g.DrawImage(cur Image, 0, 0, curImage.Width, curImage.Height )
Dim i As Integer
For i = 0 To Rds.Tables(0).R ows.Count - 1
Dim ave As Double
Dim x, y, w, h As Integer
Dim faultcounts As Integer
faultcounts = Convert.ToInt64 (Rds.Tables(0). Rows.Item(i)("E xpr1"))
ave = (faultcounts / totals)
x = Rds.Tables(0).R ows.Item(i)("XC oordinate")
y = Rds.Tables(0).R ows.Item(i)("YC oordinate")
w = Rds.Tables(0).R ows.Item(i)("Wi dthHM")
h = Rds.Tables(0).R ows.Item(i)("He ightHM")
If (ave > 0.25) Then
Dim rectan As New Rectangle(x, y, w, h)
g.FillRectangle (New SolidBrush(Colo r.FromArgb(140, 255, 0, 0)), rectan)
rectan.Y += 60
ElseIf (ave < 0.25 And ave > 0.1) Then
Dim rectan1 As New Rectangle(x, y, w, h)
g.FillRectangle (New SolidBrush(Colo r.FromArgb(140, 255, 255, 0)), rectan1)
rectan1.Y += 60
ElseIf (ave < 0.1 Or ave = Nothing) Then
Dim rectan2 As New Rectangle(x, y, w, h)
g.FillRectangle (New SolidBrush(Colo r.FromArgb(140, 0, 0, 255)), rectan2)
rectan2.Y += 60
End If
Next
g.Dispose()
End Sub

Sorry, I haven't taken the time to read your code, but there's one thing you should try - check that wherever you are drawing your graphics has AutoRedraw = True before you start drawing.

I am trying to create a garbage collection class in C++ to collect
instances of a specific class (so no general gc). The approach is to
use smart pointers and a mark and a simple sweep gc.
smartptr<B> pB;
pB = new B(args);
The constructor of B has been adjusted to register new instances with
the garbage collector. The constructor of smartptr has also been
adjusted to register new instances of smart pointers with the garbage

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.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
