This is all my code for this form:
vb Code:
  1. Public Class frmPreview
  2.  
  3.  
  4.     Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_AbrirFicheiro.Click
  5.         OpenFileDialog1.ShowDialog()
  6.     End Sub
  7.  
  8.     Private Sub OpenFileDialog1_FileOk(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles OpenFileDialog1.FileOk
  9.         AxWindowsMediaPlayer1.URL = OpenFileDialog1.FileName
  10.     End Sub
  11.  
  12.     Dim x As Image = Image.FromFile(frmPainel.logo_path.Text)
  13.     Dim WithEvents floatForm As New Form With {.FormBorderStyle = Windows.Forms.FormBorderStyle.None, _
  14.                  .BackColor = Color.Cyan, _
  15.                  .TransparencyKey = Color.Cyan, _
  16.                  .BackgroundImage = x, _
  17.                  .BackgroundImageLayout = ImageLayout.Stretch, _
  18.                  .Opacity = 0.8}
  19.  
  20.     Private Sub frmPreview_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
  21.         floatForm.Show(Me)
  22.     End Sub
  23.  
  24.     Private Sub frmPreview_Move(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Move, Me.Load, Me.Resize
  25.         floatForm.Bounds = Me.RectangleToScreen(AxWindowsMediaPlayer1.Bounds)
  26.     End Sub
  27. End Class

Btw, with VB6 can I make it transparent with no problem?
