Transfer User Commands to a DLL

Hi All,

I've transfered some user commands from my model into a .cpp file by using this script:
http://http://code.google.com/p/flex...scriptToDLL.fs
which worked very well. Apparently you'll need to change the usercommands treenode, but that is not the reason for my post.
I then tried to compile the .cpp into a DLL. That didnt work because Visual Studio display multiple errors, e.g. that it doesnt know some User Commands I am using within my User Commands.
So what i'd like to know is if there is a solution to put user commands (which call inturn other user commands) into a dll. Or will the transfer of user commands into a dll only work if there is just plain flexscript within the user commands?
The answer might be simple but because I'm not a C++ pro I've got no idea.
Thanks for any help.

I'm not sure if you can call another function using the FLEXSIMINTERFACE declaration. For that reason we always work differently. Every call to a FLEXSIMINTERFACE function call a standard C++ function. That function can then easily call another standard C++ function. So for instance


DLL_FuncA( FLEXSIMINTERFACE) {
treenode current = parnode(1);
return FuncA( current );
}

DLL_FuncB( FLEXSIMINTERFACE) {
double Value = parval(1);
return FuncB( Value );
}


FuncB( double Value ) {
do stuff..
return something;
}


FuncA( treenode current ) {
double X =....;
return Z * FuncB( X );
}

You can put the DLL_ functions as some kind of interface in a seperate interface cpp file and the other functions in a different cpp file. Normally you don't have to look into the interface file anymore.

Also remember if you need B in A you need to define B before A

Thanks Steven,

your idea is good but I'm afraid it won't solve my problem. I'd like to give you you an idea why I'm trying to convert user commands to DLL calls. Right now my model is using around 50 or so user commands. Some of them are just for writing some information to the output console, others are more complex. All user commands are pure flexscript right now. Because I'm not a huge fan of c++ I'd like to keep it that way.
On the other hand the model contains code which I dont want to give away. Therefore the idea of transfering it into a DLL.
But in order to do that I'd like to have an one-click mechanism which transfers the user commands into a cpp and compiling that into a DLL and thats it. I dont want to work with the cpp files and alter code there.
I also tried developing in visual studio once but wasnt able to get the DLL accepting my breakpoints and step thru the code (in other words attaching visual studio to flexsim). So I went back to flexscript.
Any ideas on how to solve that problem are appreciated...

Cheers,
Stephan

"That problem" means your original problem ?

What you could do if you call a usercommand from a different usercommand, don't call it with the usercommand name but call it with nodefunction() and the path to the actual flexscript node. That way it will compile and work.

Debugging works like a charm with us. If you are interested in being guided working with visual studio, we can offer a day support/training into using visual studio c++ with Flexsim.

Hi Steven,

Yes, I meant the original problem of porting user commands to a DLL.
Thanks for your offer. I keep that in mind in case the current project (which ends in a few weeks) will be extended. For the time being I'll play around with your suggestions and see whats working best.

Cheers,
Stephan
