ScriptUtils

Easy to use, hi-performance ASP file upload component with progress bar indicator. Let's you upload multiple files with size up to 2GB to a disk or database along with another form fields. Works with large posts, any character set (including unicode utf-8). Contains one-click multiple files/folders download with on-the-fly compression (Using BinaryWrite/BinaryRead).

      Hi-performance text file logging for ASP/VBScript/VBA applications. Lets you create daily/weekly/monthly log files with variable number of logged values and extra timing and performance info.
       Lets you work with safearray binary data in VBS/JS. It also enables conversion between binary and String data using several code pages. ZLib compress and uncompress functions. Lets you transfer files using compressed stream from a client to server using IE.
      This library also enables calling of some Kernel and Advapi functions (performance, timing, sleep, configuration ...) and enables native work with INI files.

Additional notes

LogFile is a COM class specially designed as a free-threaded, hi-performance logging object in Application scope of ASP/ASP.Net pages. It also works with other script engines in VB Script and JScript (ASP, ASP.Net, WSH, CHM, HTA), VB Net, Visual basic (VBA - VB 5, VB 6, Word, Excel, Access, …), C#, J#, C++, ASP, ASP.Net, Delphi and with T-SQL OLE functions - see Use ByteArray object article. You can also use the object in other programming environments with COM support, such is PowerBuilder.
