Binary file access and other filehandling in WinAPI

by Allan Greis Eriksen

Summary

This package uses the Win-API to access binary files.
Filedelete, Filemove, Filecopy and Filerename are functions that uses Win-API and can be used instead of dataflex own commands. I have experienced some problems with the erasefile command with many files to be deleted on a novell network.
Directory and File search included. Get last access, last write and created dates and time with fileattributes. Search only files, directories or both at the same time.

Binary File Access



This package uses the Win-API to access binary files. It was written in VDF5 but there should not be any problems to use it with later versions of VDF.
Since Direct_input is not able to handle binary files under Windows NT I was forced to write my own routines using the Windows API.
These functions will work under Windows 95/98/Me and Windows 2000/NT/XP.

Filenumbers are not limited to 10 but only to system resources! So opening file "test.txt" with filenumber 100 is perfectly legal. These functions are limited to 2 Gb files!

The documentation is in the files.
