FIX: LSTRCMP and LSTRCMPI May Fail with Non-US Regional Settings
Article ID: 182053
Article Last Modified on 7/11/2005
APPLIES TO
- Microsoft Platform Software Development Kit-January 2000 Edition, when used with:
This article was previously published under Q182053
SYMPTOMS
The LSTRCMP and LSTRCMPI string-comparison APIs may erroneously report that
two strings fail to compare under the following conditions:
- Windows 95 is configured for a Regional Setting other than "English
(United States)".
- One of the strings is located in a 16-bit discardable code segment which
has been discarded.
CAUSE
If the regional setting is anything other than English (United States), the
string-compare call is thunked to 32-bit string-compare functions in
Kernel32. If the segment containing a string to be compared has been
discarded, the thunking code does not force a segment reload.
RESOLUTION
You may be able to work around this problem using one of the following
methods:
- If a segment contains a string to be compared with LSTRCMP or LSTRCMPI,
do not mark that segment as discardable.
- If a segment is discarded before calling LSTRCMP or LSTRCMPI, touch the
string in some way to force the segment to be reloaded.
STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed
at the beginning of this article.
This problem was corrected in Windows 2000.
