How exactly can I change the opacity using an HScrollBar? I found some code on Google but I couldn't modify it to do what I wanted it to do.

Code:

Private Sub hbarOpacity_Scroll(ByVal sender As _System.Object, ByVal e As _System.Windows.Forms.ScrollEventArgs) HandleshbarOpacity.Scroll
Me.Opacity = 0.1 + hbarOpacity.Value / 100
Me.Text = Me.Opacity.ToString
End Sub

Try this:

Code:

Private Sub hbarOpacity_Scroll(ByVal sender As _System.Object, ByVal e As _System.Windows.Forms.ScrollEventArgs) Handles hbarOpacity.Scroll
' Just set the trackbar value range to 10-100
Me.Opacity = hbarOpacity.Value / 100
End Sub

If that doesn't do it, check that your trackbar is actually named hbarOpacity.

Getting a bunch of errors.

Things you should have done w/o any help:

Remove the 2nd line of code (don't need it)
Name the items correctly if not done so already
Set the min and max

then you wouldn't have any errors
