The two constructors are declared in content.h:
content(void);
content(string ident);
and defined in content.cpp:
content::content(void){
}
content::content(string ident){
id = ident;
}
Then, in contents_manager.cpp:
content contents_manager::get_content(string id){
content c;
for(int i=0; i<size; i++){
c = contents_list.at(i); // contents_list is a vector<content>
if(c.id == id)
return c;
}
return NULL;
}
The only thing I think can cause this is the line in red, according to what
is said here
<http://msdn2.microsoft.com/en-us/library/c6kkh778%28VS.80%29.aspx>vector.at(i)
returns a reference so, why can't I do this? Compiling there is no error...
I don't know if what is happening has anything to do with Xerces or is only
because my C++ programing "knowledge"...sorry.
