Hello,
Verify the value of eax

The return value is the length of the string, in bytes, excluding the terminating null character.
If the index parameter does not specify a valid index, the return value is CB_ERR

The title of the messagebox couldn't be null (error in title)
put the index in edx,not eax

mov edx,eax
.if edx != CB_ERR
    .if edx != 0   ;NULL chain
         invoke MessageBox,hWnd,addr hbuffer,SADR("Title"),MB_OK
    .else
         invoke MessageBox,hWnd,SADR("Empty String"),SADR("Title"),MB_OK
    .endif
.endif
