How to Read From Fixed-width Text Files in Delphi
The demo shows how to open and read log file (test.log)
The demo uses TextFieldParser object which provides a way to easily and efficiently parse structured text files, such as logs. The TextFieldType property defines whether the parsed file is a delimited file or one that has fixed-width fields of text. In a fixed-width text file, the field at the end can have a variable width. To specify that the field at the end has a variable width, define it to have a width less than or equal to zero.
