I am writing a C++ wrapper and need to marshal a
System::Drawing::Rectangle to an LPRECT. Is this possible, and if so,
how do I go about doing this?

Thanks,

Chris

Well you can't pass a direct pointer since they don't share the same
internal representation. So you have to declare a RECT struct, fill it
with the values from the Rectangle, and then pass the RECT address to
the funtion.
