Is there a way to get the value of GlobalVariable from Code using getvarnum()?

I´ve tried to get and set the value of a GlobalVariable from code, but all that I tried seems useless.

setvarnum(Model.find("MODEL:/Tools/GlobalVariables/testDLL"), "Data", 8);
double c = getvarnum(Model.find("MODEL:/Tools/GlobalVariables/testDLL"), "Data");
print(c);

and also I tried

setvarnum(Model.find("MODEL:/Tools/GlobalVariables"), "testDLL", 8);
double c = getvarnum(Model.find("MODEL:/Tools/GlobalVariables"), "testDLL");
print(c);

I know that a variable could be setted in a easy way just assignt the new value like this

testDLL=20

But that does not work for me and the type of project that I am working on. I need to get and set the variables from external dll (c++ dll - dllMaker)

NOTE.- The above code for set and get works for objects, but no with GlobalVariables

Accessing the data node directly sets the reset value. You can set and get that using the .value attribute as a string:

treenode gvdatanode=Model.find("Tools/GlobalVariables/myGlobalVariable/Data");
gvdatanode.value=mynewvalue;

If you want to set or get the current value try using executestring:

executestring("myGlobalVariable=4");    //set it 
return executestring("myGlobalVariable");   // get it
