I used to call a dll (named A.dll) which was written by myself in Flexsim, and the A.dll was invoked successfully. However, if I added extra some code in A.dll, which command the A.dll to call B.dll that was written by another programmer (B.dll was not written in the grammar that flexsim specified) , A.dll can not be invoked successfully.
Can Flexsim call a third party dll? Or, in another way, should the B.dll also be written in the grammar that flexsim specified?
Yes, you can call a third party dll from a dll built with the FlexSim DLL Maker. That will work just fine.
If you are having trouble with doing that, then you'll need to post more information so that we can duplicate the issue you are having to explain why it is happening. In general, that procedure works fine.
Thank you for your timely reply. But I still don't know whether the third party DLL should be written with Flexsim DLL maker.
No, it doesn't have to be. Hence: third party DLL. It can come from wherever.
For example, the FlexSim Emulation Module dll connects with various connectivity dlls from third parties, such as libmodbus.dll and OTBx64.dll (the Softing OPC Toolkit).
