How to Use a Matrix to Rotate in VB.NET

Visual Basic.NET (VB.NET) is computer programming language by Microsoft. VB.NET is a declarative, object-oriented and structured language that was influenced by Microsoft's .NET framework. VB.NET is commonly used in conjunction with C#.NET or ASP.NET to create web applications. It is also commonly used to create desktop software applications for the Windows operating system. The VB.NET "Matrix.Rotate Method" is implemented into a project to rotate an object according to the angle that you specify.

Instructions

1. Launch the Microsoft Visual Studio.NET integrated development environment application. Open the Visual Basic.NET project in which you want to implement code for the "Matrix.Rotate Method."

2. Copy and paste the following code example and implement it into your Visual Studio.NET project:

   Public Sub RotateMatrix (ByVal e As PaintEventArgs)

   Dim pencil1 As New Pen(Color.Blue, 1)

   Dim pencil2 As New Pen(Color.Red, 1)

   e.Graphics.DrawRectangle(pencil1, 250, 150, 300, 200)

   Dim myMatrix As New Matrix

   myMatrix.Rotate(45, MatrixOrder.Append)

   e.Graphics.Transform = myMatrix

   e.Graphics.DrawRectangle(pencil2, 250, 150, 300, 200)

   End Sub

   Edit the "Graphics.DrawRectangle Method" parameters and the angle rotation according to your needs.

3. Press "Ctrl" and "S" to save the Visual Basic.NET project.
