Ventana software support forum

Hello,
I wrote a program to call vendll32.dll with VB6.
It worked when the version of vendll32.dll is 5.8.
After I upgraded it to version 5.11.
It stoped at DAT2VDF command
Is there any change for this command in new version?
Here is my code.
Pls help to fix this problem.
Thanks
in the version 5.11. the value of Result is 0 which mean it fail.

Do you get any errors when you convert the dataset in vensim itself?

Are you using 5.11a? There was a problem (briefly) in one earlier version.

Can you describe the problem?

Hi
No error when I convert the dataset in vensim itself.
I have upload the dataset here.
The version of Vensim is 5.11. not 5.11a.
I am still trying to figure out where the problem came from.
The OS is WinXP but in a virtual system (VirtualBox).
But I don't have this kind of problem when I have old version.
If this is not a common problem, then I have to do more check in my VB program.

Hi
After I reinstall to version 5.10e
The problem solved.
Can I think it is the bug of version 5.11?

Correct - the problem was introduced in 5.11 and is now fixed in 6.0.
