I am having problems with flickering when drawing squares
to a picture box. Heres my main form code:
Code:
Public Class FrmGame
Public ArrayBlocks(15, 30) As Block
Public BlockSize As New Size(15, 15)
Private Sub FrmGame_Load(ByVal sender As Object,
ByVal e As System.EventArgs) Handles Me.Load
'Reduce Flicker'
SetStyle(ControlStyles.DoubleBuffer, True)
SetStyle(ControlStyles.AllPaintingInWmPaint,
True)
End Sub
Private Sub FrmGame_Paint(ByVal sender As Object,
ByVal e As System.Windows.Forms.PaintEventArgs) Handles
Me.Paint
'Draw Game Board To Picture Box'
Dim GameBoard As New GameBoard
GameBoard.Draw(ImgMain.Handle)
'Draw First Line Of Blocks To Picture Box'
Dim X As Integer
Dim Color1 As Color = Color.Blue
Dim Color2 As Color = Color.LightBlue
Dim InitialLoc As New Point(0, 0)
For X = 0 To 14
ArrayBlocks(X, 0) = New Block(BlockSize,
InitialLoc, Color1, Color2)
ArrayBlocks(X, 0).Draw(ImgMain.Handle)
'Update Initial Location'
InitialLoc.X += 15
'Change Block Colors'
If Color1 = Color.Blue And Color2 =
Color.LightBlue Then
Color1 = Color.Red
Color2 = Color.Yellow
Else
Color1 = Color.Blue
Color2 = Color.LightBlue
End If
Next X
Me.Invalidate()
End Sub
End Class
The Rectangle which is my game board is drawn as per
normal no flickering, however when the 15 blocks/squares
are drawn they are all flickering for some reason. I may
be doing something wrong as until now i've been creating
basic games with picture boxes. If anyone has any advice
i would appreciate it greatly.

Make sure that the form AutoRedraws.

Use a backbuffer.
