Ventana software support forum

Hi all,
I am trying to start a simulation from Excel:

retval& = vensim_command("SPECIAL>LOADMODEL|D:\source code\Vensim\name_of_model.vpm")
If retval& = 0 Then Exit Sub
retval& = vensim_command("MENU>SYNTHESIM|O")
If retval& = 0 Then Exit Sub
retval& = vensim_command("SYNTHESIM>AUTO|0")
If retval& = 0 Then Exit Sub

The model must be run with the double precision DSS, but when I run it from Excel it runs in the single precision DSS. How can I tell from VB to start the double precision simulation?

Thanks,
Davide Moraschi

Have you edited the function call declarations to call into the double precision dll?

Replace "vendll32.dll" with "vdpdll32.dll" and it should work.

Yes it WORKS!
Thanks a lot.
