Module Name:
|

|
|
|

|
Chollian2000Plus.cpp
|
||
|
|

|
|
Abstract:
|
||
|
|
|
||
|
|
The app has a binary logon.ocx which uses sub-classed editbox as password
|
||
|
|
editbox. It does not hook all messages (whistler seems has more message
|
||
|
|
than win2k's), so when the mouse drags through it, the password typed will
|
||
|
|
be shown as plain text, the fix is to apply ES_PASSWORD to this specific
|
||
|
|
EditBox.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
This is an app specific shim.
