• Visual C++ Question about properties

  Hi, I have some trouble with "property". I currently have a managed object with a set of properties, which acts as a layer on top of another one, in order to display some informations in a property grid. When I create a simple property, like "property float Depth;" it works fine. Then, if I write : property float Depth { float get(void) { m_Depth = 1.0f; return(m_Depth); } } It also works fine.
