I'm writing a C++.NET 4.0 program that involves a form in Visual Studio 2010. I'm adding a GraphicsPath to a Form. Here's part of my code:
GraphicsPath^ gp=gcnew GraphicsPath();
gp->AddString("Hello world!", gcnew FontFamily("Arial"), (int) FontStyle::Italic, 26, (new PointF(100,100)), StringFormat::GenericDefault);
Compile and I get an error
void System::Drawing::Drawing2D::GraphicsPath::AddString(System::String ^,System::Drawing::FontFamily ^,int,float,System::Drawing::PointF,System::Drawing::StringFormat ^)' : cannot convert parameter 5 from 'System::Drawing::PointF *' to 'System::Drawing::PointF'
So I change it to
GraphicsPath^ gp=gcnew GraphicsPath();
gp->AddString("Hello world!", gcnew FontFamily("Arial"), (int) FontStyle::Italic, 26, *(new PointF(100,100)), StringFormat::GenericDefault);
and get more errors

It should be simple, just convert the pointer to the PointF it actually points to but things get complicated for some reason I don't know.
Could you tell me the correct way to use the System::Drawing::Drawing2D::GraphicsPath::AddString() function? Remember I'm using C++, not C#
Have you tried:
gp->AddString("Hello world!", gcnew FontFamily("Arial"), (int) FontStyle::Italic, 26, PointF(100,100), StringFormat::GenericDefault);
this is at least the correct method signature
