Ventana software support forum

Hi, Still the result is the same. I generally create just one variable and try and test my function. Could it be that the copy that i have is corrupt ? everything else works just fine.... I could understand if only my code did not work or the dll i create does not work but in this case the code and ...

Hi, I have tried to install vensim on another PC and I re-complied the dll and I ran the debugger I am posting the screenshot of the debugger. you can see that the values passed by vensim is 0.00000 for both the functions cosine() and inrange() The code and the visual project is the one which is pro...

ok so the dll works may be there is some problem with the installed copy of vensim. I will try it on some other pc.

Thank you

I tried passing int as well as float still the result is the same.
Do I need to add any library files in the project while build it.
e.g. vensim.lib

Still using %lf does not help printing the right values.
Float or double nither of them is being passed. It still prints 0.00000
I tried compling the DLL using the batch file provided but still the DLL behaves the same.
I have tried re installing the software but it does not help.

Hi, I am trying to build a dll using the venext.c however when I run the dll in vensim it does not pass double values. I write the value passed in a text file. every time a double is passed it write the value passed as 0.0000 but when I pass a literal/string it is passed properly. e.g if i pass cosi...

Thank you for your quick response. My confusion with regard to using JNI is that the call needs to be initiated by a java module. In my case it is being called from vensim external function which would be c++ ( through the DLL) then I would need to have observers which would notify the java program ...

Hi, I wanted to know if I can use DDE to exchange data from a java application. I have a small application which I built in java which implements few algorithms. I want vensim model to run the java application and get those values while the simulation is running. e.g I start the simulation, for some...

I did read the manual but it was bit unclear to me as i have never used Vensim before.
But your clarification would help .

Thank you for your reply.

Hi I have a model in vensim which needs to reach out to another external model to compute a value. The External model would be built in c++ so it can be accessed using the DLL. Can we pause the simulation till the external function computes the value and sends it back to the vensim model. Flow of ev...
