(VB) Call Form1_Paint after Form1_Load has been called.

[liambiscuit]

I think the title is self-explanatory, but here's some extra:

What I am trying to do is so that whenever the end of Form1_Click is reached, Form1_Paint is called.

Code: [Select]

Form1_Paint(sender,e)Returns error: Unable to cast object of type 'System.EventArgs' to type 'System.Windows.Forms.PaintEventArgs'.
Which is what I anticipated.

If I put this:

Code: [Select]

        Dim p As System.Windows.Forms.PaintEventArgs
        Form1_Paint(Me, p)I am given the warning that 'p' is used before defined (It never IS defined) and later on, when trying to draw a rectangle in form1_paint: Object reference not set to an instance of an object.

So how do I either define 'p' or call form1_paint without causing error later on?

Here is my whole code (Not that long, not that complicated, promise :: the three lines of '' 's is where the errors occur):

Code: [Select]

Public Class Form1
    Public elist As New List(Of Point)
    Public txt As Integer
    Public dot As Image = Image.FromFile(Application.StartupPath & "\data\dot.png")

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Form1_Click(sender, e)
    End Sub

    Private Sub Form1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Click
        elist.Add(New Point(Windows.Forms.Cursor.Position.X, Windows.Forms.Cursor.Position.Y))
        elist.Add(New Point(Windows.Forms.Cursor.Position.X, Windows.Forms.Cursor.Position.Y))
        ''
        ''HERE IS WHERE FORM1_PAINT IS CALLED
        ''
    End Sub

    Private Sub Form1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint
        If Not elist.Count = 0 Then
            For Each point In elist
                Dim rect As Rectangle = New Rectangle(point.X - 5, point.Y - 5, 10, 10)
                e.Graphics.DrawRectangle(Pens.Orange, rect)
                ''
                '' THe above line is where an error is caught when using "form1_paint(me, p)"
                ''
            Next
        End If
    End Sub
End Class

Mother f....

I hate google.

Hate it.

Yahoo FTW.

The first 30 minutes of googling, no success.

Two minutes after posting, i learn 'Invalidate()'

Calls all the *_paint functions as soon as your GPU can handle it. and my ATI Radeon 3200 can draw a box almost instantly.

*sigh*

Remove the thread, admin. Or leave this for other morons like myself.
