Get started with Direct3D VB.net Programming

I am a VB programmer. I have been developing database applications. After a long time, I feel bored and want to change my taste, but I have no time to learn and materials, I happened to see the learning experience written by others on CSDN, so I quickly entered the door. Good things are not exclusive. As I learned, I changed the original C # program to vb.net code, but the idea is the same and it is only for your reference.

Imports Microsoft. DirectX
Imports Microsoft. DirectX. Direct3D

Public Class Form1
Inherits System. Windows. Forms. Form

# Region "code generated by Windows Form Designer"

Public Sub New ()
MyBase. New ()

This call is required by the Windows Form Designer.
InitializeComponent ()

Add any initialization after InitializeComponent () is called
Me. SetStyle (ControlStyles. AllPaintingInWmPaint Or ControlStyles. Opaque, True)
End Sub

Form override dispose to clear the component list.
Protected Overloads Overrides Sub Dispose (ByVal disposing As Boolean)
If disposing Then
If Not (components Is Nothing) Then
Components. Dispose ()
End If
End If
MyBase. Dispose (disposing)
End Sub

Required by the Windows Form Designer
Private components As System. ComponentModel. IContainer

Note: The following procedure is required by the Windows Forms designer
You can use the Windows Form Designer to modify this process.
Do not use the code editor to modify it.
<System. Diagnostics. DebuggerStepThrough ()> Private Sub InitializeComponent ()

Form1

Me. AutoScaleBaseSize = New System. Drawing. Size (6, 14)
Me. ClientSize = New System. Drawing. Size (292,266)
Me. Name = "Form1"
Me. Text = "Form1"

End Sub

# End Region
