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.
