Using the Pervasive Direct Access Components

Using the Pervasive Direct Access Components

You install the PDAC components by unzipping the components from an archive to a directory of your choice (installdir). You must ensure that any Delphi or C++ Builder IDEs on your system can locate the components after they are unzipped.

Follow these steps to set C++ Builder project options to reflect the INCLUDE and LIBRARY paths for PDAC. These can be added to the default options, so the steps are unnecessary for every project using the Pervasive components.

To add Pervasive Direct Access Components to the INCLUDE and LIBRARY paths in C++ Builder

1

Select ProjectOptions, and choose the Directories/Conditionals tab.

2

Add installdir\sdk\pdac\Delphi?\include to the Include Path, where installdir represents the directory where you installed the SDK. Replace the ? with the version of RAD Studio you are using.

3

Also add installdir\sdk\pdac\Delphi?\lib and installdir\sdk\pdac\Delphi?\lib\dcu to the Library Path, separated by a semicolon. Replace the ? with the version of RAD Studio you are using.

After the Include and Library paths are set properly, you can use the Direct Access components in exactly the same way as the corresponding Embarcadero components.

Delphi 2006, Delphi 2007 and C++ Builder 2007

Pervasive PSQL provides support for Delphi 2006 and Delphi 2007 and for C++ Builder 2007. Use the following steps to incorporate Delphi 2006, Delphi 2007, or C++ Builder 2007 into your environment.

►

To add the Delphi 2006, Delphi 2007, or C++ Builder 2007 packages and path information to your environment.

1

Click Components > Install Packages > Add.

2

Select the design packages.

3

Add the paths to the Delphi compiled units (DCUs) and interface files (INTs).

Since Delphi 2007 and C++ Builder 2007 are binary compatible with Delphi 2006 (BDS 2006), all of your existing Embarcadero package libraries (BPLs) should work without any modification. Note that Delphi 2007 and C++ Builder 2007 declare compiler variable VERSION_180 and VERSION_185.

Follow these steps to add components to the compiler IDE for the following editions of RAD studio:

•

RAD Studio 2009

•

RAD Studio 2010

•

•

RAD Studio XE2 (32-bit only)

•

•

•

•

►

To add the RAD Studio packages and path information to your environment

1

Click Components > Install Packages > Add.

2

Browse to the following PDAC design time components and select the ones you need. Note that these are design time packages. For run time, see Deploying an Application Based on PDAC.
