Visual Basic.Net How do you Draw Pixel onto PictureBox1?

[Xilef]

This is really starting to piff me off now, no where on the internet is a working scrap of code that draws a single pixel onto a picture box based on x/y co-ordinates.

I would like to know if anyone has the programming knowledge on how do draw a pixel like this? :mystery:

EG: Draw(X,Y,R,G,B)
draws a single pixel on PictureBox1 at position X and Y with colour RGB

Please anyone with VB.net knowledge help me.

Thank you!!!

The Picturebox has a Paint method that uses the e.Graphics property.

You can do something like this:

 

    Private Sub PictureBox1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles PictureBox1.Paint

        e.Graphics.DrawLine(Pens.Black, 0, 0, 5, 5)

    End Sub

 

It makes a little line for you. All drawing onto controls is handled by the control's Paint sub.

Intellisense says this (basically):

DrawLine(<Pen Color>, <starting x>, <starting y>, <ending x>, <ending y>)

Experiment with that

EDIT:

You can even draw text directly:

e.Graphics.DrawString("String!", New Font("Arial", 8.5, FontStyle.Regular), Brushes.Red, 0, 0)
