Buffer as a parameter

[limpit]

Hi, i am trying to use a buffer before sending it to a canvas, and I am having problems finding out how to set the buffer as a parameter in one of my classes. Im doing this:

void Muestrate(BufferedGraphics ^buffer);

This is the same way i used to set a canvas a parameter, although it wont work with the buffer. I keep getting a syntax error. Any help please? Thanks in advance.
