i'm struggling long time on how rectify error. please me. doing wrong?

in beginning have guard block:

#if !defined(tree_search_box) #define tree_search_box 

which good. mean call #define tree_search_box means tree_search_box defined nothing. when compile, preprocessor scans files, , replaces tree_search_box . breaking code, because you're trying compile this:

int ::get_quest_dynstr(int idquest, lptstr opstr, pdynobj dynpobj){ ... 

where :: means global namespace.

there 2 ways fix this:

• change guard block

   #if !defined(tree_search_box_something_else)  #define tree_search_box_something_else 

• change class name.

---

what find interesting don't errors fact try compile:

class  : public standalone_conn{ 

but turns out can define anonymous class this:

class : baseclass {    //bla }; 

i guess learned today :)
