DDS out of memory

Hello, I've kinda learned how to program a bit using Patrice Pellands book and I tried to make a program.this was my problem. I had an out of memory exception. Here was the code:

Public Class Form1

Private Sub open_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles open.Click

OpenFileDialog1.Filter = "DDS Texture (*.dds)|*.dds"

If OpenFileDialog1.ShowDialog() = DialogResult.OK Then

End If

End Sub

End Class

Ok, I run the program then when I choose a DDS file, the Out of Memory Exception occurs in this line of code, it says it has no memory how can i fix this

It's supposed to open and display DDS Images or Direct Draw Surface

can anybody help thanks.
