.NET newbie ques.

I am starting to switch from VB6 to .NET and I can't change a form'2 backcolor using code. For example using a button's click event, what would you do. VB6 was Form1.backcolor = vbgreen

If you view the code for your form, you'll see a collapsed region labeled, "Windows Form Designer generated code." Expand that region, and you can see the code .NET uses to initialize your form. If you use the Properties window to set the form's BackColor to green, then examine the generated code, you'll find this line:

Me.BackColor = System.Drawing.Color.Green

That's exactly what you would put in your button's Click event to change the BackColor at runtime.

When I do that everything turns green, even the button, why?

Interesting! I'd never noticed that before. Look up BackColor in VB.NET's online help. Notice:

The BackColor property is an ambient property. An ambient property is a control property that, if not set, is retrieved from the parent control. For example, a Button will have the same BackColor as its parent Form by default.

So, can you figure out what you need to do in order to prevent the button's BackColor changing when you change the form's BackColor?

I found out in a book that unless you specifically assign a collor to a control, it will take the color of the form it is attached to.
