RSP Zip Compressor OCX 1.5.1

Release date(Thu Sep 10 17:12:36 2009)

ActiveX OCX to compress , uncompress , delete , test and list zip files

What is new in the version 1.5.1 (Thu Sep 10 17:08:26 2009) Small internal update, requires rspzip.dll, rspunzip.dll

What is new in the version 1.4.0 (16/Nov/2004 12:00) Fixed a bug that will not allow the compression of a unique file in the selection , in this case the control will return a 'nothing to do error' , to reproduce the problem just select a file that is available in the folder with the files to compress and select it to compress , as you will see the control will not compress the file , only selections that has a wildcard on the selection will work , fixed in this version , now you can compress single files without problem , minor bugs fixed also

What is new in the version 1.3.0 (09/Feb/2004 15:41) Added CPU detection code , added cpu priority selection code , enhanced the compression and decompression engine , the version 1.3.0 can compress files 10 to 15 percent faster than version 1.0.0 , fixed some xml parser error codes that may return wrong information , added more error verifications , fixed minor bugs

The upgrade is free to licensed users for two years

Description

The RSP Zip Compressor OCX can handle zip files with or without passwords , created with pkware or Info-zip based compressors

The compressor and decompressor is based on Info-zip

Due to some known Info-Zip limitations the control has several workarounds to avoid problems , and a page with the list of workarounds or known Info-Zip bugs is available in the RSP Info-Zip Known Bugs

The code receive information about the zip file , destination directory , password , arguments and options regarding compression or decompression using an xml like parser that can accept several commands

The list of commands and description of use is available in the page RSP Zip Compressor Commands

With the parser it is more easy to detect errors in the information passed to the compressor or decompressor and the commands are intuitive

It will avoid ambiguities on the compression or decompression code , since the parser will evaluate each command and return an error code if the command isnot accepted

And it will inform about missing commands or modifications required in the commands in order to work

With the parser it will be more easy to compress or decompress zip files since you only need to know about the commands and all the commands are intuitive making it a good solution to use zip compression in any application using only a few lines of code , and with full zip compression error handling

For each error , a description of the error will return , with the description it is very easy to understand what goes wrong , and how to avoid the same error in the future

The goal of this software is to provide as a development tool a control to both OCX and .Net framework development capable of generating a full zip utility running very fast in order to make it possible to anyone interested in zip compression to use it without possible bugs .

The sample project available with the package will show how to construct the commands and how to use the zip , unzip and list zip functions

We are open to discussion about a better way to receive information about the compression or decompression

If you have a better way to pass information to the control regarding the compression or decompression  , send email to info@rspsoftware.8x.com.br  

And inform about bugs in the control as soon as possible , with the information we can track and fix the possible problems quickly

The version 1.3.0 functions and their descriptions (14/Apr/2004 11:14)

Method About

Public Function About()

This function will bring up the aboutbox of the control

Method ControlName

Public Function ControlName() As String

This function will retrieve the name of the control

Method GetCPUBrandString

Public Function GetCPUBrandString() As String

This function will retrieve the brand string name embedded in the installed processor ( if available , of course )

Method GetCPUSpeed

Public Function GetCPUSpeed() As String

This function will retrieve the speed of the processor , notice that the function needs one second to finish

Method GetCPUVendor

Public Function GetCPUVendor() As String

This function will retrieve the vendor string name embedded in the installed processor

Method Goto_RSPSoftware

Public Function Goto_RSPSoftware()

It will just start your default browser and connect to our primary homepage at http://rspsoftware.clic3.net

Method ListZip

Public Function ListZip(ByVal filename As String, Optional ShowFolders As Boolean = False) As Long

This function will list the information available on the zip file using the event ZipInformation , so , for each entry in the zip file the event will be raised with all the information passed as arguments

filename : the Zip file to retrieve the information

ShowFolders : this boolean value will define whether the folders entry will appear in the information passed in the event

Winzip don't show the folders entries , this mean that there is more information on the zip file that are not visible with Winzip

Setting the ShowFolders to true will make the folders available on the zip file to appear as additional entries

For full compatibility with Winzip just set ShowFolders to false ( default )

Method RSPBrowseForFolder

Public Function RSPBrowseForFolder(Title As String, InitDir As String) As String

This is a help function to the control , in order to add folder selection directly in the control

A call to this function will return the selected folder , with UNC path support

Method RSPZipCancel

Public Function RSPZipCancel()

This function will cancel the execution of the compression or decompression

Method RSPZipCompress

Public Function RSPZipCompress(Command As String)
