HOWTO: Create a DAO Setup that Installs Jet IISAM Files

• The Microsoft Foundation Classes (MFC), included with:
  • Microsoft Visual C++, 32-bit Editions, versions 4.0, 4.1

SUMMARY

The DAO setup included on the Visual C++ 4.0 or 4.1 CD-ROM in the \MSDEV\REDIST\DAO directory does not install the Microsoft Jet IISAM files that are used by DAO for accessing databases such as Microsoft Excel and dBase. However, you can modify the DAOMIN.RUL InstallShield file included in the DAO SDK to create a new SETUP.INS file for the DAO Setup. By using the new .INS file with the existing DAO Setup, you can create a new DAO Setup that installs all of the IISAM files.

Because a modification is needed to an InstallShield .RUL file, you need to install InstallShield from the Visual C++ 4.0 or 4.1 CD-ROM.

MORE INFORMATION

Once you have the DAO SDK and InstallShield installed on your development machine, follow the steps below to have your setup program install IISAMs in a silent fashion without prompting the user:

1. Open the DAOMIN.RUL file located in the Daosdk\Setup directory using Notepad. Scroll to line 138, and see the following:
   
   SAMPLE CODE -- from DAOMIN.RUL line 138, BEFORE editing

   
         /////////////////////////////////////////////////////////////////// 
         bIncludeISAMS = FALSE;
   
         if (bIncludeISAMS) then
           //Ask the user which ISAM drivers to install
           fnDetermineUserSelectionDAO();
         endif;
   
         END OF SAMPLE CODE
         ///////////////////////////////////////////////////////////////////  




2. Comment out the bIncludeISAMS = FALSE and comment out the call to fnDetermineUserSelectionDAO() as follows:
   
   SAMPLE CODE -- from DAOMIN.RUL line 138, AFTER editing

   
         /////////////////////////////////////////////////////////////////// 
         //bIncludeISAMS = FALSE;
   
         //if (bIncludeISAMS) then
           //Ask the user which ISAM drivers to install
         //  fnDetermineUserSelectionDAO();
         //endif;
   
         END OF SAMPLE CODE
         ///////////////////////////////////////////////////////////////////  




3. Save the file, and run the InstallSheild Command Line utility COMPILE.EXE, targeting the freshly edited DAOMIN.RUL file:

   
         [PATH]COMPILE [PATH]DAOMIN.RUL 




4. When the COMPILE.EXE utility completes its task, an intermediate file called DAOMIN.INS is created. Rename this file to SETUP.INS and replace the SETUP.INS located in the REDIST\DAO directory with the newly-created version.



5. Open the SETUP.BAT file using Notepad. Change SETUP NOSDK to:

   
         SETUP -S NOSDK 




6. Run SETUP.BAT. SETUP.EXE uses the new SETUP.INS and installs IISAMs in a silent fashion without prompting the user.
