Hi All

Could you not use a message interface in Windows to pass variables? e.g.

- C program invokes Eu program
- Eu program sends custom message(s) to C program to get variables
e.g. var = SendMessage( hCProgram, UM_GET_VAR, var_id, 0 )
- C program returns variable value or pointer to struct etc.

This seems equivalent to calling functions in the parent program to 
me...
