Point class constructor problems can be caused by regional settings. Dot vs. comma stuff: http://silverlight.net/forums/t/4142.aspx

I’m still hopeless!!!

Solution 1
Can’t really call it a solution. Just inverses the problem..

double x = Convert.ToDouble("11,5");
double y = Convert.ToDouble("0,44");
Point TestPoint = new Point(x,y);

Solution 2
Didn’t really work for me either. I guess it’s my fault, but i had problem with constructing Point from results of calculations:

Solution 3
My solution. It’s cool until you use it to create a new point. But as you try to give value to a Point property, like GradientOrigin it fails.

double x;
string _x = (2.0 / 3.0).ToString(System.Globalization.CultureInfo.InvariantCulture);
x = double.Parse(_x, System.Globalization.CultureInfo.InvariantCulture);
double y;
string _y = (1.0 / 2.0).ToString(System.Globalization.CultureInfo.InvariantCulture);
y = double.Parse(_y, System.Globalization.CultureInfo.InvariantCulture);
Point TestPoint = new Point(x,y);


Extensive tests with September refresh

(with no results…)

Lamp.Center = new Point(double.Parse(_x, InvariantCulture), double.Parse(_y, InvariantCulture));

}

I really should give up on this!

I got the idea to change the CurrentCulture of the thread, just to find out it doesn’t work (of course I took the thirty minutes of breakpoint craze to find it out first hand).

The answer:

For your laugh:


// Simple value giving
// and temporary changing thread culture
CultureInfo OldCulture = CultureInfo.CurrentCulture;
CultureInfo NewCulture = CultureInfo.CreateSpecificCulture("en-US");
// this line breaks:
System.Threading.Thread.CurrentThread.CurrentCulture = NewCulture;
Lamp.Center = new Point(xRelative, yRelative);
System.Threading.Thread.CurrentThread.CurrentCulture = OldCulture;
