Opacity changer

Basically i want a button to change the opacity to a certain percent, anyone got code for me?

 

Be more specific in what you want. I'm guessing you want either a horizontal or vertical slider that changes the opacity when you move it up/down or left/right. See this: http://www.vb-helper.com/howto_net_form_opacity.html
Try Google first before you ask people to do it for you. It really weren't hard typing 'opacity vb.net' into google and hitting enter.
