TITLE   :BUG: App Studio GP Faults in RCDLL.DLL When Opening a .RC file
PRODUCT :Microsoft C Compiler
PROD/VER:
OPER/SYS:
KEYWORDS:kbResourceEd kbVC kbGrpDSToolskbbuglist kbfixlist

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - The App Studio, used with:
    - *EDITOR Please do not choose this product*Microsoft Visual C++ for Windows* use 1699 
    - *EDITOR Please do not choose this product*Microsoft Visual C++ 32-bit Edition* use 241, 265, 225 
-------------------------------------------------------------------------------

SYMPTOMS
========

Using App Studio to open a .RC file that has been modified and saved causes App
Studio to generate a General Protection fault in module RCDLL.DLL. However, App
Studio can successfully open .RC files that have not been modified and saved.
Under Visual C++ 2.0, 32-bit Edition, the integrated environment will GP-fault
upon startup.

CAUSE
=====

This problem can be caused by having the system date and time set to a value
which is greater than January 19, 2038, 7:14:07 P.M.

RESOLUTION
==========

Set the system date and time to the correct values.

STATUS
======

Microsoft has confirmed this to be a problem in the Microsoft products listed
above. We are researching this problem, and will post new information in the
Knowledge Base as it becomes available.

MORE INFORMATION
================

The problem has to do with the fact that the C run-time time related functions
use a type of time_t to represent time values. Currently time_t is defined to be
a signed long. The maximum number of seconds that can be stored in a signed long
is 2,147,483,647. Since the time related functions use 00:00:00 (midnight),
January 1, 1970 as their base, the maximum time and date that can be represented
with a time_t type is January 19, 2038, 3:14:07 A.M.

Only .RC files which have been modified and saved on a system that is currently
using the incorrect time and date will show the problem. For example, .RC files
which are included with the samples provided with the compiler can be
successfully loaded into App Studio. This is because their last modification
time was set when they were initially created. However, once a .RC file has been
modified and saved on the system with the invalid time and date, it can no
longer be loaded into App Studio.
