What is TDBF?
TDBF is a freeware native data access component for Borland Delphi, C++Builder and Kylix, and for FreePascal. It allows you to create very compact database programs that don't need any special installer programs. In fact the code to access your database is compiled in your project executable file. It takes only a few kilobytes in your executable and doesn't need any other external files to run.
Key features
Downloads
Warning: TDbf does not work in personal editions of Delphi, C++Builder and Kylix. TDbf is a TDataset descendant and TDataset is not available in the personal editions.
Here you can download latest version of component, documentation and demonstration project.
Installation - Delphi, C++ Builder
Step 1: Uncompress the ZIP file in your component directory. For example C:\Program Files\Borland\Delphi5\Components\
Step 2: Launch Delphi. In the Delphi IDE select File->Open Project. If you are using:
| Delphi | select the file tdbf_dXr.dpk, where X is your delphi version number |
| C++ Builder | select tdbf_cXr.bpk, where X is your bcb version number. Click Compile. You've now compiled the runtime part of the component. |
Step 3: Open the 'design' package, which is named with a 'd' at the end instead of an 'r'. Note that Delphi 3 and 4 and BCB 4 don't have runtime and design packages, so you compile and install the single one without 'd' or 'r'.
Step 4: Open TDbf_Demo.dpr, the demo program and run it.
Please contact us in the forum if you have any installation problems.

Already, one year! I can not believe how many email I received about TDBF. New version 4.009 has a better PackTable function, TDBF packs indexes now. It do not pack memo fields yet, does anyone knows a technique to do that without having to rewrite the whole .dbt and .dbf file?
