Re: [TRNSYS-users] Error using getLabel-function in C++ type

[gernot.steindl@gmx.at]

Hello Marcello,

thanks for your reply.  
I would prefer to set the IP from the Simulation Studio in the type.  I think I should try contact the distributor and tell them my problem. I’ve found some posts describing the same behavior of GetLabel in a C++ type. But sadly there is no solution…

If anybody has a hint, please let me know.

Best regards,
Gernot
