HPTourGuide.cpp
|

|
|
|
||
|
|
Abstract:
|
||
|
|
|
||
|
|
The application causes Explorer to crash when
|
||
|
|
a tour is selected. To fix we are eating LVM_GETITEMA
|
||
|
|
messages if the window handle matches the ListView
|
||
|
|
that the app was sending to.
|
||
|
|
Fix for Whistler bug #177103
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
This is an app specific shim.
