PowerTCP Zip Compression for ActiveX Features
Zip ActiveX Control
Use the Zip control to add file compression/decompression and advanced encryption to applications written in many development environments. These quality tools represent state-of-the-art component design. Our customers deserve nothing less:
- Supports AES encryption.
- Fully integrated with the FileStore object. Add files to the FileStore object and zip, or add a compressed file to the FileStore and unzip.
- Flexible memory operations. Compress/uncompress data in memory.
- Simple QuickZip and QuickUnzip methods enable file compression and decompression with only one line of code!
- Fastest compression available.
- Large files over 2 gigabytes is supported (zip64).
- WinZip®, PKZIP®, and UNIX gzip compatible.
- Visual Studio .NET (.NET Framework)
- Visual Basic (VB)
- Visual C++ (VC++)
- C++ Builder
- Office 97/2000
|Algorithm||The compression algorithm that is used for the control.|
|BackgroundOperation||Specifies whether compression operations are synchronous or asynchronous.|
|DoEvents||Allows for the processing of application message events when BackgroundOperation is False.|
|FileStore||The object that is used for fine-tuned zip, unzip, and file manipulation functionality.|
|ProgressSize||Sets when the Progress event will be raised based on the number of kilobytes compressed or decompressed.|
|Abort||Aborts any method and releases all resources.|
|About||Show the About Box.|
|QuickUnzip||Extract from a compressed file into a specified location.|
|QuickZip||Compress a file or a group of files.|
|Disk||Raised when a new disk is needed during a spanning process.|
|Error||Raised when an error or warning condition occurs.|
|Progress||Raised periodically to indicate compression or decompression activity.|
How easy is the Zip ActiveX component to use? Check out the VB examples below.
Example 1: The first example demonstrates compressing several files into a single zip file.
' Add items to the FileStore using the Add method
' Zip all of the files into "zippedfiles.zip"
Example 2: The second example demonstrates compressing and AES encrypting several files into a single compressed file.
' Add files to the FileStore.
' Encrypt them with the strongest possible level of AES encryption.
Zip1.FileStore.Add "C:\Test\file1.txt", , , "mypassword", zipAESMaximum
Zip1.FileStore.Add "C:\Test\file2.txt", , , "mypassword", zipAESMaximum
Zip1.FileStore.Add "C:\Test\file3.txt", , , "mypassword", zipAESMaximum
' Zip all of the files into "encrypted.zip"
