I want to call a *.dll ,so I use the call library node . In the *.dll ,there is a function "unsigned long Receive (unsigned long a, unsigned long b,unsigned long , vi_pointer *p) "
struct vi
{ unsigned int aa;
unsigned int bb;
byte cc;
byte dd;
} vi_poiter
The fourth parameter is a pointer of struct ,so I setting this as "pointer to handle" and connect this input to a cluster .
BUt this way is useless. The parameter can't transfer correctly.
how can solve this ?
thank you very much
