SUMMARY
=======
If you want an application to obtain Windows 95 logo compliance, you should not
use SQLInstallODBC to install ODBC components. Instead, use the
SQLInstallDriverManager, SQLInstallDriver, SQLConfigDriver (if necessary) and
SQLInstallTranslator (if necessary), as described in the Readme25.txt file that
comes with the installation of the "ODBC Desktop Driver Pack 3.0." This file can
be found in the Windows\System directory. The APIs listed below make appropriate
configurations in the registry; they do not copy the files to the destination
directory. It is the task of the installation program to copy the installation
files to the target directory.
The following is a list of the Installer APIs that can be used by an installation
program:
- Use SQLInstallDriverManager to install the driver manager components.
- Use SQLInstallDriver to install the driver.
- Use SQLConfigDriver to optionally configure the driver after it has been
installed by SQLInstallDriver.
- Use SQLInstallTranslator to configure translators, if they are used by the
drivers.
The advantage of using the above APIs in the 32-bit installation programs for
ODBC drivers is that they will make the transition to install under ODBC 3.0
easier.
This article illustrates the usage of the SQLInstallDriver API with the help of a
C program. The documentation of the SQLInstallDriver can be found in the "ODBC
2.0 Programmer's reference and SDK guide".
MORE INFORMATION
================
The following is the C program that illustrates the usage of the
SQLInstallDriver API:
INSTDRV.C:
This program demonstrates usage of SQLInstallDriver for configuring 32-bit
drivers. To configure the driver, this program uses the Odbc.inf file in one
case, and uses just the driver attributes in another case. Note that usage of
driver attributes will be more portable than using Odbc.inf files in the long
run.
