Getting and setting variables at a given time

[Herve - IPSIS]

Hello Tony,

I would like to get and set model variables at a given time from an ActiveX component.
I tried to call OCX_SETVALUE and OCX_GETVALUE commands, using the following syntax for the variable name : "myvariable[mysubcriptelement]@mytime" (for example : C in Atmosphere[Deterministic]@2035)

Unfortunately, it looks like only the end time value is read and set, whatever time is written after the "@" character.

Could you please tell me how to read and update those values from an ActiveX component ?
Best regards,
Hervé

There is a new version uploaded that will allow "parameter@time" now. Let me know if it works ok for you.

Thank you a lot

This works now.

I've tried "parameter@time" for a variable of type "data" but it did not work. Does it work for all types of variables or for only variable of type "auxiliary"?

What errors are you getting? It should work, but only if a data point exists at the specific time you are asking for.

I've used your example DLL VBDemoControl in order to get the variable value.
Here is my test project. I try to get "Data Variable@2005", it does not work. But "Data Variable Auxiliary@2005" works fine.

I've tried this project, there is no call to get the data (or I cannot see it).

Can you give me step by step instructions please?

I open the project with Sable Developer, then run the DLL VBDemoControl in "External Dlls" folder. In DLL's window, I try to get data.

I'll have to raise this as a Vensim bug, I have no workaround for now. Sorry.
