Hi,
I'm having a picturebox which I need to animate, i.e. to move and change the image.

VB

Imports System
Imports System.Drawing
Public Class Form1

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        Static x As Integer = 5
        Static y As Integer = 0
        Static flip As Integer = False
        If y Mod 2 = 0 Then
            Me.PictureBox1.Image = My.Resources.Resource1.Bird_l
        Else
            Me.PictureBox1.Image = My.Resources.Resource1.bird_r
        End If
        If Me.PictureBox1.Left >= 500 Then
            x = -5
            flip = True
        ElseIf Me.PictureBox1.Left <= 0 Then
            x = 5
            flip = False
        End If
        If flip = True Then
            Me.PictureBox1.Image.RotateFlip(RotateFlipType.RotateNoneFlipX)
        End If
        Me.PictureBox1.Left = Me.PictureBox1.Left + x
        y += 1
    End Sub
End Class

While running it's showing error in the line:-

VB

Me.PictureBox1.Image = My.Resources.Resource1.bird_r

- "Parameter Not Valid"

Why is the error?

Thanx

You need to check how you have added the resources My.Resources.Resource1.Bird_l and My.Resources.Resource1.Bird_r as the code works for me after testing it with my own images. Does intellisense give any indication that the declaration of these resources is wrong? When I add an image to a resource file I use My.Resources.myImageName.

Ya the images are added to the resource file. It's showing a runtime error.

Well you code works fine, so I would investigate whether the image resources are correct.
