most revelant between *.exe or *.dll for external code

[Marc-Henri]

Hi,

I have a little question, what is the most revelant to execute external code from C, C++, MatLAB, etc ?

I think for C code we have two possibilities, call dll or cal executable. What is the adventage and/or drawback for each solution ?

Thanks for reading. Marc.

I would definitely recommend a dll for most situations, since that's the purpose of a dll - to be called from another application.

Are you calling code written in C, etc. from LV or code written in LV from C, etc.?

Actualy it's just a reflexion with my self. My question is about the integration of C or C++ or Visual C++ code.

What appening with this code if we have to stop the application ?

Does it create a new thread when you call a dll ?

That depends on how you setup the CLFN.  You can either configure the CLFN to run in a unique thread, or you can configure it to run in the UI thread.  The decision should generally be based on whether the dll is thread safe or not.
