Hi Ryan,

in my GUI extension (Visual C++ 4.0) I declared the variables which have 
to be accessed from POV-Ray and the external program by

  // Global variables which could be read by POV-Ray (as client) 
  // and also the server program
  #pragma data_seg("TVPOVCOM_GLOBAL")
    HWND hPOVWindow_g = 0;
    HWND hAppWindow_g = 0;
    BOOL boEnabled_g = FALSE;
    char acRenderFile_g[_MAX_PATH] = "\0";
    ...
  #pragma data_seg()

In the DEF-file I included the following:

  SECTIONS 
    TVPOVCOM_GLOBAL READ WRITE SHARED

I didn't get a shared InitStruct working for myself. So, if I want to 
start a rendering by my program, I call a function StartRender(filename) 
which stores the filename in acRenderFile_g. Then it drags a (hopefully) 
none existing file "tvpovcom.StartRender" to POV-Ray. POV-Ray then calls 
the DragFunction in which you can start the render process of 
acRenderFile_g if DropType==dfRealDrop and the name of the dragged file 
is "tvpovcom.StartRender".

I know, this is a bit circumstantial, but it works fine.

Bye,
Friedemann
