Re: [TRNSYS-users] DYNAMICDATA function in C++

Hi Daniel,

 

It it hard to tell without looking @ some code, but I would bet on some argument type mismatch, or array size mismatch (your arrays must match the constants in TrnsysConstants.f90).

The TRNSYS kernel functions mainly want arguments passed by reference, like in

int a; doit(&a);

 

Set a breakpoint on the line that calls the function , F5 in DevStudio, navigate to Trnsys.exe, point to the deck to run, inspect the variables when the breakpoint is hit. F11 will basically debug into the TRNDll by using the debug version (you need to recompile TRNDll with a Fortran compiler).

 

Hope that helps (a little),

 

Werner

Objet : [TRNSYS-users] DYNAMICDATA function in C++

 

Dear all,

 

I’m trying to create a new component in C++ with a dynamicdata function.

 

It works when I build the solution in C++, but pulls out following error when I run this component in TRNSYS:

 

“Access violation at address 100048CC in module ‘TRNDLL.DLL’. Read of address 00000002”

 

Does anyone has some experience in using the dynamicdata function in C+ and can help me out?

 

 

Thanks very much in advance
