The information in this article applies to:

 - The Microsoft Foundation Classes (MFC), included with:
    - Microsoft Visual C++, 32-bit Editions, versions 4.0, 4.1 
    - Microsoft Visual C++, 32-bit Enterprise Edition, version 4.2 
    - Microsoft Visual C++, 32-bit Professional Edition, version 4.2

SUMMARY
=======

The documentation for the CDaoWorkspace::CompactDatabase function does not
specify the format of the password parameter. The password must be in the
following format: ";PWD=password". If the password is not in the correct format,
you may see the following error:

   Can't find installable ISAM

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

The documentation for the CDaoWorkspace::CompactDatabase function gives the
following information about compacting a password-protected database:

static void PASCAL CompactDatabase( LPCTSTR lpszSrcName, LPCTSTR
    lpszDestName, LPCTSTR lpszLocale, int nOptions, LPCTSTR lpszPassword );

Parameters
lpszPassword   A password, used when you want to compact a
               password-protected database. Note that if you use the
               version of CompactDatabase that takes a password, you must
               supply all parameters.

There is no information about the format of the password parameter. However, the
documentation for the DBEngine.CompactDatabase function has the following
information:

Syntax
DBEngine.CompactDatabase olddb, newdb [, locale [, options
    [, ;pwd=password]]]

Part           Description
password       An optional string argument containing a password, if the
               database is password protected. The string ";pwd=" must
               precede the actual password.

Sample Code
-----------

      /* Compile options needed: none
      */ 

      /* The following code will compress the database C:\DB1.MDB, which has
       * a password of "MyPassword"
      */ 

       try
       {
           CDaoWorkspace::CompactDatabase( _T( "C:\\DB1.MDB" ),
               _T( "C:\\DB2.MDB" ), dbLangGeneral, dbVersion30,
               _T( ";PWD=MyPassword" ) );
       }
       catch( CDaoException* e )
       {
           AfxMessageBox( e->m_pErrorInfo->m_strDescription );
           e->Delete();
       }

STATUS
======

This problem was corrected in the documentation for Visual C++, version 6.0.
