Re: [TRNSYS-users] Access violation

I 'm sorry for reply you so late,It has been a long time for me to understand how to debug in CVF,Now I finally found out the "access violation" maybe caused by calling IMSL Library（I use it to solve a non-linear equation set）,My question is whether it is ok to call IMSL library in user made component?

Thanks for your early reply,I add my component to the TRNDll project and I run it in debug model. but it still can not work after I chosen the dck file ,
crashed with the information" First-chance exception in TRNExe.exe (TYPE207.DLL): 0xC0000005: Access Violation"

An access violation is a very generic error that can be caused by many different problems.

You may get a little more information about the cause of the error if you go into the component control cards in Simulation Studio and turn on "debug mode." This will cause your simulation to run a bit more slowly but will perform some additional checks that may lead you to a solution.

If that does not work then there should be a CVF66 compiler workspace already set up in the ..\Trnsys16\Compilers\ directory that will allow you to recompile the TRNDll itself. I would recommend that you add your component to the TRNDll project then run your simulation from the compiler (instead of from the Studio). This will allow you to step one line at a time through the code in your component and see where the access violation is taking place. There are some instructions on how to do this located in the 08-ProgrammersGuide manual.

Lastly, please be aware that Trnsys16 was replaced by v17 in 2009 and by v18 earlier this year. Official support for older versions continues for a year after the release of a new version. After that time the distributors try to provide help on earlier versions when they are able and have some spare time to do so.

kind regards,

Dear TRNSYS user,
  I'm trying to create a new component for a solar cooling system.I have installed the  CVF6.6 compiler and TRNSYS16.
my component model code was compiled without error and the type201.dll was successfully generated,but when I trying to run it
in the trnsys studio,I got an error "Access  violation at address 08E63E0F in module'Type201.dll'.Read of address 00000002 ".

 Any help or hints greatly appreciated.

  Regards.
