Hello,

how can I use list (http://www.cplusplus.com/reference/list/list/) and maps (http://www.cplusplus.com/reference/map/map/) inside a ASCIL code ?
Where do I have to initialize them inside the code ?

Thanks

Did you want these STL objects to persist even after the study function returns?

Hello,

thank you for your response.
Yes, I want them to persist since I want to use them in my studies.

Actually, I just would like to use STL objects (vector, list, map, queue) like Sierra does in the "studies8.cpp" under "ACS_Source" directory (the line I am referring to is 6688 number, the *.cpp file is studies8.cpp itself).
Nevertheless, everytime I try to use list for instance, Visual Studio gives me incorrect compiling errors (I have installed all teh directories required by Sierra to compile and I have followed correctly the Sierra guide to use MS Visual Studio as a compiling environment)

Thanks, enjoy your sunday

Not sure what the compiler errors are, but be sure to include these header files at the very top of the source code file:
#include <iterator>
#include <vector>

You will need others when using the list, map, queue containers.

Hello,

thank you for your response.
I have added those headers to my code but Visual Studio does not compile: I have added the code reported by you under "studies8.cpp" but it still does not compile.
Where should I add the "std::vector<char*> Tokens;" code ?
Could you provide a simple code that compiles on your side ?

Thanks

Have a look at the example in /ACS_Source/RequestValuesFromServerAndDraw.cpp

Also, we do not provide programming help. It is your responsibility to examine the compiler error messages and resolve the problem.

Thank you.

I have just seen that the STL expression must be in the form: vector<TypeHere> *MyVector...not vector<TypeHere> MyVector...

Have a good week

Only if you are defining a pointer to it and dynamically creating it.

Also be sure to prefix it with std::

Hello, sorry for "re-opening" this thread...
Would you be so kind to provide and example of "dinamically creating" the vector ?

For instance, I create the pointer to the vector like this:

std::vector<int> *MyAttempt;

but once I try to write something like: MyAttempt = new std::vector<int>();
Visual Studio does not compile the solution...

Could you be so kind to help me please ?

Thanks

This should work:

std::vector<int> * VectorContainer = new std::vector<int>;

If it does not work, what are the Visual C++ error messages?
