First, if you are using Win32::GUI, you shouldn't need to import SendMessage() yourself. Second, you cannot just make **it up as you go along :) The description of the TVM_GETNEXTITEM message from the page I linked is:
The wparam argument should be one of the following flags, not the length of a buffer
And the lparam argument should be either null or the handle returned from a previous call, not a pointer to a buffer. The basic mechanism is,
Obviously, you will need to loop/recurse at each level to optain all the siblings & children at each level. It's upto you to decide whether you depth first or breadth first. The return value from the SendMessage is the item handle to each node in the tree. As well as using this as an argument to get the next sibling or child in the tree, you also use it to send TVM_GETITEM messages to each of those items to retrive the TVMITEM(EX) structure that contains the data & state that is the node.
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".
The "good enough" maybe good enough for the now, and perfection maybe unobtainable, but that should not preclude us from striving for perfection, when time, circumstance or desire allow.
