Hello,
Technically there is no OLE method to "apply the indicator" but...
you can create an universal template that will have a pane with the following
single-liner formula:
#include "generated_code.afl"
and your program will:
a) create a file called "generated_code.afl"
and then
b) issue OLE command to open template described above
Best regards,
