Win32 API question: How to get a window/chart handle?

["Gerrit Jacobsen" <jrt@xxxxxxxxxx>]

I don't think you can get the handle while being in the dll - I might
be wrong there - however:

Why can't you assign within the DLL a unique ID (some counter) 
whenever the DLL is called and no ID or 0 ID is passed to it.

First call:
TS passes '0' ID to DLL -> DLL creates ID
DLL passes new ID to TS -> TS saves ID in variable that doesn't get
overwritten on every new tick. TS consecutive calls to DLL: TS passes
stored ID to DLL -> DLL uses ID
