SDF-CSV DataSet v.2.05

DB-Aware Components > Direct DB Access > Text

By Orlando Arrocha.

Freeware + source 04 Jun 2002


Access any text file as it were a table from a database. Indicate only the file, attach a DataSource and you may use any DataControl with it. Now, must of the methods of a regular DataSet are included, so you may add, delete, modify and filter records.

Field names and sizes may be defined on design or runtime, just before opening the file, or definitions may be stored on an schema file (even inside the data file).

Useful methods let you save the file with less fields, remove blank records, or saving the changed file in another.

Two classes are included and a sample:

  • TSdfDataSet - for comma delimited files
  • TFixedFormatDataSet - for fixed length files.
