Not sure what you're asking - do you mean an "empty" spot when rendered?

.Net, C# if you would but VB is ok
a hole in a form
a hole in a form
If you set the TransparencyKey, and have a region that is a that color, there will be a hole bored through the form.

System.Drawing.Drawing2D.G
// start with a rectangle that represents the whole form
gp.AddRectangle(new Rectangle(0, 0, SizeIN.Width, SizeIN.Height));
// add an ellipse...which is removed from the rectangle above
int w = FormIN.Width / 4;
int h = FormIN.Height / 4;
gp.AddEllipse(RectangleIN)
// create a Region from the GraphicsPath and set it...
FormIN.Region = new Region(gp);
