Hello,

I tried the ActiveX sample project with C-Roads and got some troubles in accessing model variables :
Before launching a simulation run, I can get and set any value.
After having run the simulation, I can only read, but not set any value.

Here are the steps to reproduce the problem :

• 1) Add the ActiveX sample VBDemoControl to C-Roads sable project (using the files stored in

  MODEL.zip

  (234.78 KiB) Downloaded 674 times

  )
  2) Open C-Roads project in Sable developper
  3) Open the VBDemoControl window
  4) Create a new run with aggregation value "15 Region"
  5) Using the VBDemoControl window, set the following values :
  • Pct change in FF emissions sable[China] = -50
    ff change target year ecr sable[China] = 2030
    ecr target by rs sable[China] = 2
  6) In the VBDemoControl window, click "Sim Run"
  => The simulation runs, the CO2 FF emissions of China decrease
  7) Using the VBDemoControl window, set now the following value :
  Pct change in FF emissions sable[China] = +30
  => The value is not set. Pct change in FF emissions sable[China] value is still -50

Can you email the entire project to me? I cannot figure out what is wrong with just the OCX to use.

Hello,

I got it working : C-Roads scripts reinitialize the SYNTHESIM mode. I called the same Venapp commands from my OCX and could modify values after a simulation run :

SYNTHESIM>AUTO|0
SYNTHESIM>AUTO|1
SYNTHESIM>GO|
SetData(data, value)
SimRun()
