#2347 closed Bug (Fixed)

_WinAPI_GetMonitorInfo() returns incorrect data.

Reported by: Valik Owned by:
Milestone: Future Release Component: Standard UDFs
Version: 3.3.9.4 Severity: None
Keywords: Cc:

Description

The following line of _WinAPI_GetMonitorInfo() is incorrect:

If Not _WinAPI_MoveMemory(DllStructGetPtr($Result[$i]), DllStructGetPtr($tMIEX, $i + 1), 16) Then

DllStructGetPtr() is 1-indexed, not 0, so the code as originally written returns garbage. Actually it causes rcMonitor to return cbSize and the first 3 elements of rcMonitor and it causes rcWork to return rcMonitor. None of which is correct.

The fix is simple enough:

If Not _WinAPI_MoveMemory(DllStructGetPtr($Result[$i]), DllStructGetPtr($tMIEX, $i + 2), 16) Then

Better yet rewrite that part of the code to be less "clever" and more sane. Remember folks, clean and working code is better than clever broken code.
