Works with safearray binary data - save/restore binary data from/to a disk, convert to a string/hexstring, codepage/charset conversions, Base64 conversion, etc.

|Find||Returns a Long specifying the position of the first occurrence of the data binary array.|
|FindRev||Returns a Long specifying the position of the first occurrence of the data in binary array from the end of data.|
|CharSetConvert||Converts bytearray (as CharSet/CodePage code page) to another charset/code page.|
|Left||Returns Length bytes from the left of array|
|Mid||Returns data from middle of the array.|
|ReadFrom||Reads data from file.|
|Right||Returns Length bytes from the right of array|
|SaveAs||Saves the ByteArray data as a file.|
|SetSize||Sets a new size of binary data. If old size is greter than new size, data is truncated to the new size.|
|Base64||Converts data between ByteArray (safearray of bytes) and Base64. Works as a Base64 encoder and decoder from binary (bytearray) or from Unicode String.|
|ByteArray||Contens of ByteArray object as byte safearray or one byte from array.|
|CodePage||Code page for converting between binary and String data.|
|HexString||Returns contents of the ByteArray as hexadecimal string (base16 string)|
|CharSet||String representation of a CodePage. This value specifies the code page of a source binary data for binary to unicode String conversion.|
|Length||Length of the data.|
|Punycode||Returns unicode String as punycode encoded string. You can directly convert data from/to any charset to punycode using this property.|
|String||Returns (or sets) the data as a string. The binary data are converted to/from a unicode string using CodePage.|

Huge ASP upload is easy to use, hi-performance ASP file upload component with progress bar indicator. This component lets you upload multiple files with size up to 4GB to a disk or a database along with another form fields. Huge ASP file upload is a most featured upload component on a market with competitive price and a great performance .

This installation package contains also ScriptUtilities library. Script Utilities lets you create hi-performance log files , works with binary data , you can download multiple files with zip/arj compression, work with INI files and much more with the ASP utility.
ByteArray is a COM class specially designed to work with Microsoft Windows Scripting engines - VB Script and JScript in Active Server Pages or WSH and in CHM or HTA applications. It also works with 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.
