C# applications can't use XP style control?

Buttons always look in the old style. Is it also true in your computers or just my computer went crazy?

Code:

---

public class x
{
        public static void Main()
        {
                System.Windows.Forms.Application.Run(new xx());
        }
}
public class xx:System.Windows.Forms.Form
{
        System.Windows.Forms.Button xxx=new System.Windows.Forms.Button();
        public xx()
        {
                xxx.Location=new System.Drawing.Point(100,100);
                xxx.Text="XP?";
                this.Controls.Add(xxx);
        }
}

I've created a "FILENAME.manifest" file, but the button still looks in the old style.

Please let me know if my computer went crazy. I'll reinstall .NET Framework or even Windows.

It was simeple. I found it on the internet.

The solution is,

Set control's FlatStyle property to System.

That's all.
