CInfoZip is an MFC class, wrapping functionality of
a great and powerfull free ZIP/UnZIP libraries. CInfoZip was designed to bring
compression power to AutoMail, a small
handy application, that will help you sending files by e-mail directly from
Windows Explorer context menu or from DOS command prompt. CInfoZip does not
perform compression itself, it provides easy-to-use interface to InfoZip DLLs
(included in CInfoZip package).
Add CInfoZip files to your project
Add CInfoZip files to your project and place ZIPDLL.DLL and UNZDLL.DLL files
into your EXE working directory (\DEBUG\ or \RELEASE\). You may use only one of
these DLLs if you need to support compression or decompression only.
Create CInfoZip class instance
Within your code create CInfoZip class and add initialization method calls:
The first two functions load InfoZip DLLs, retrieve pointers to their procedures
they will be using, and return TRUE if all necessary data was successfully
retrieved and FALSE otherwise. The last one initializes both ZIP and UnZIP DLLs.
To add/extract files to/from archive please call:
BOOL CInfoZip::AddFiles(const char *pszArchive, char **paFiles, int iFileCount);
BOOL CInfoZip::ExtractFiles(const char *pszArchive, const char * pszTargetFolder);
where pszArchive is a NULL-terminated string, containing full path and name of
the archive file, paFiles - array of NULL-terminated strings containing file
names with full path, iFileCount is a number of files in paFiles array and
pszTargetFolder is a full path of the folder extracted files will be placed in.
Change ZIP parameters
When using these methods compression and extraction are performed with some
predefined parameters set in:
BOOL CInfoZip::SetDefaultValues(CZipParams *pParams);
BOOL CInfoZip::SetDefaultValues(CUnzipParams *pParams);
If you need to perform ZIP operations with different parameters, you should
create a structure of type CZipParams/CUnzipParams, fill it with your values
(or call SetDefaultParams and then change some structure members) and then call
BOOL CInfoZip::Execute(CZipParams *pParams);
BOOL CInfoZip::Execute(CUnzipParams *pParams);
Finishing working with CInfoZip

loaded DLLs by calling:
