Sending strings via PostMessage

[Megadime 0]

I'm trying to send strings via PostMessage from AutoIt to C++. The way I understand it this is possible by using string pointers and handing them to the wparam and lparam parameters of PostMessage. Is that correct?

If it is, how am I supposed to do that in AutoIt?

For strings you must allocate memory inside called application's memory (address) space.

Look at sources of  _GUICtrlListView_GetItemText() or _GUICtrlListView_SetItemText() in "C:\Program Files\AutoIt3\Include\guilistview.au3" 

Also search forum for WM_COPYDATA to see the right way of interprocess communication.

Anyway, Megadime likely understood wrong.

PostMessage is asynchronous function. That means it returns without waiting for receiver to process it, i.e. string buffer will be destroyed before processed.
