Custom Color Help? (Solved)

Hi! I'm having trouble setting a custom color for a rectangle. I used a solidbrush to use the color, and brush1 to = solidbrush. This code does not work with e.Graphics.FillRectangle(LBrush, 0, 0, 50, 50). Both ways just give me the form with a huge red x over everything. What is wrong? Thanks!

vb Code:

Public Class Form1
 
    Dim LColor As Color = New Color
    Dim LBrush As SolidBrush
 
    Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
 
        NewColor()
 
        Me.Invalidate()
 
    End Sub
 
    Private Sub NewColor()
 
        Randomize()
        LColor = Color.FromArgb(Math.Round(Rnd() * 150) + 100, Math.Round(Rnd() * 150) + 100, Math.Round(Rnd() * 150) + 100)
        LBrush.Color = LColor
 
    End Sub
 
    Private Sub Form1_Paint(sender As Object, e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint
 
        Dim Brush1 As Brush = LBrush
 
        e.Graphics.FillRectangle(Brush1, 0, 0, 50, 50)
 
    End Sub
 
End Class

Found my mistake: Solidbrush works but it must be created and set in the same block (Form1_Paint).

vb Code:

Public Class Form1
 
    Dim LColor As Color = New Color
 
    Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
 
        NewColor()
 
        Me.Invalidate()
 
    End Sub
 
    Private Sub NewColor()
 
        Randomize()
        LColor = Color.FromArgb(Math.Round(Rnd() * 150) + 100, Math.Round(Rnd() * 150) + 100, Math.Round(Rnd() * 150) + 100)
 
    End Sub
 
    Private Sub Form1_Paint(sender As Object, e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint
 
        Dim LBrush As SolidBrush = New SolidBrush(LColor)
 
        e.Graphics.FillRectangle(LBrush, 0, 0, 50, 50)
 
    End Sub
 
End Class

When you create any disposable object, make sure that you dispose it when you're done with it. This is usually done with a Using block if possible, e.g.

Code:

---

Using LBrush As SolidBrush = New SolidBrush(LColor)
    e.Graphics.FillRectangle(LBrush, 0, 0, 50, 50)
End Using
