Sending messages to Flexsim

Hi,

I’m experimenting with Flexsim for a while now. I’m getting pretty familiar with the program, only one problem I can’t solve.

I’ve got an external source which delivers some parameters, for example the conveyer speed.
The structure that I’m trying to set-up: When changes occur in the external source, an external program will pass these changes through within a (Flexsim) message. The reason for this structure is that I do not want Flexsim to check constantly for changes in the source.

I understand this is possible and I did find some experiments based on VB. Now I have no knowledge of VB, so I want to do it in C++ but don’t know where to start.

What is the best way to send these messages with C++?


(I’m using: Flexsim 4.5, MS Windows XP, MS visual C++ 2008)

Thanks in advance,
Cedric

Hi Cedric,

Have you thought about using a DLL? If you use the set up that Flexsim has made for creating a DLL (see: http://www.flexsim.com/community/for...read.php?t=382)
you can send flexsim messages from within a C++ environment. How you want to get the trigger for the messages into the DLL, you probably know yourself.

Dear Steven,

Thanks for your quick reaction!

I have thought about using DLL’s. But by using DLL’s Flexsim has to look constantly if something has changed. In small models this is no problem, but when we go big, this will increase the sequence time of Flexsim. Now I want the smallest sequence time, so it gets nearby real time and won’t miss any changes. By ripping the processes apart, you will get smaller sequence times.
