Drawing to Bitmaps

[System_Error]

Can someone help me with this?...

I want to draw simple graphics such as rectangles or lines to a bitmap instead of using the Me.creategraphics method. The only problem is: I don't know how to draw to a bitmap.

here's a simple example i made for you , it makes a bitmap / then makes 4 rectangles in the bitmap ( different colours )

Dim bmp As New Bitmap(200, 200) '/// create a bitmap 200 x 200 in size
        Dim grp As Graphics = Graphics.FromImage(bmp)
        Dim rcts(3) As Rectangle
        rcts(0) = New Rectangle(0, 0, 100, 100)
        rcts(1) = New Rectangle(100, 0, 100, 100)
        rcts(2) = New Rectangle(0, 100, 100, 100)
        rcts(3) = New Rectangle(100, 100, 100, 100)
        Dim p As New Pen(Color.Red, 5)
        With grp
            .DrawRectangles(p, rcts)
            .FillRectangle(New SolidBrush(Color.Blue), rcts(0))
            .FillRectangle(New SolidBrush(Color.Green), rcts(1))
            .FillRectangle(New SolidBrush(Color.Yellow), rcts(2))
            .FillRectangle(New SolidBrush(Color.Violet), rcts(3))
        End With
 
        '/// test by putting the bitmap as a picturebox's image ( if you wish to do so )
        PictureBox1.Image = bmp
