    No, not stupid. 
there is an error in the treeview

   there's a different between the source an the headerfile.
The function prototype:
    PNTVCOMPARE is defined as int(*)(long,long,long)
in the Lib:
    PNTVCOMPARE is used as int(*)(int,int,int)
  So you see where the error is, the function is called correct,
 the definition  is incorrect, and thus the message
 
 linker error "Unresolved ... in main.obj":
 int __stdcall __export CompareFunc(long,long,long)
{
  return 0;
}


Here how to solve the problem:

modify commctrl.h like this:

typedef int(CALLBACK *PFNTCOMPARE)
    (LPARAM lParam1,LPARAM lParam2,LPARAM lParamSort);

with

typedef int(CALLBACK *PFNTCOMPARE)
    (int lParam1,int lParam2,int lParamSort);

That's all, good luck <g>
