Version 5.20

• Distributed Samples Updated
  The wwHttpDemo sample distributed application samples have been update to better demonstrate XML messaging rather than using the original cursor based transfer. While the original sample was little more lightweight using XML is easier and now more common. The samples have been updated to work more consistently and look a little more professional. Specifically the Customer List sample that allows browsing and updating of customers has a new look. The sample is accessible from the Enterprise demo page or by running wwHttpDemo.exe.

• wwPOP3 updates
  There have been a number of tweaks and fixes to the wwPOP3 library to make it more reliable. Message body parsing has been improved to return content in a more reliable fashion.

• wwHttp class Improvements
  The wwHTTP class provides client HTTP services to FoxPro applications that need to call on and retrieve Web based URLs and retrieve its content. wwHTTP has been made easier yet by providing the ability to directly download to files using the HttpGet method. In fact the more low level HttpGetEx functionality should be rarely required any longer as all features are now accessible with the easier HttpGet() method. New flag added that gets around the apparently frequent problem of connecting to servers that have invalid or expired security certificates. Although we don't recommend doing this (get the server fixed!) this flag will ignore most certificate errors and behave more closely like a browser.

• wwHTTP::HTTPGet adds a download to file capability
  To further reduce the need to use HTTPGetEx() for HTTP access the HttpGet() method now supports a 4th parameter to download HTTP content directly to file. This is useful for downloads of large content so that the output is moved into memory and returned as a string - useful for multi-megabyte downloads. This functionality was one of the last features that had to resort to using HttpGetEx(). HTTPGetEx() still is the low level interface to wwHTTP and HttpGet() delegates to it, but user code is recommended to use the easier to use HTTPGet() method.

• Several enhancements to wwIPStuff's Email handling
  wwIPStuff now adds the cExtraHeaders at the top of the email message which means that the extra headers take precedence over any default headers wwIPstuff adds later on. A new AddHeader() method has also been added to make it easier to add custom Headers to emails. This in turn means you can override wwIPStuff's default headers and should alleviate, in most cases, any restrictions on headers used that existed before. wwIPStuff now also handles return receipts with new lReturnReceipt property which sends a receipt to the sender. The cMailServer property now supports port numbers as part of the mail server address (mail.myserver.com:2525) which overrides the nPort property.

• wwIPStuff SMTP Logging added
  Added support for logging the SMTP session to a log file so the entire conversation with the server is visible. Implemented in wwIPStuff::cLogFile. This makes it considerably easier to troubleshoot connection and transmission problems in this increasingly Email hostile computer environment we find ourselves.

  *** ACTION REQUIRED:
  Make sure you update both wwIPStuff.dll and wwIPStuff.vcx in your applications. There was a change in the DLL to provide this feature. The new code will not run with the old DLL, but old code will work with the new DLL.

The cMailServer property now supports port numbers as part of the mail server address (mail.myserver.com:2525) which overrides the nPort property.

• wwPop3 Fixes
  There have been a few fixes that deal with reading the content containing delimination characters (.'s specifically). The code has been reworked to try and read the message buffer based on message size rather than parsed reading of the content dynamically.

Version 4.62

• Several enhancements to wwIPStuff's Email handling
  wwIPStuff now adds the cExtraHeaders at the top of the email message which means that the extra headers take precedence over any default headers wwIPstuff adds later on. This in turn means you can override wwIPStuff's default headers and should alleviate, in most cases, any restrictions on headers used that existed before. wwIPStuff now also handles return receipts with new lReturnReceipt property which sends a receipt to the sender. The cMailServer property now supports port numbers as part of the mail server address (mail.myserver.com:2525) which overrides the nPort property.

• wwUtils adds a wwUtils.SetAcl function
  You can now assign access rights on a directory or single file by calling SetAcl. You can assign rights to files and directories and assign users or groups. Rights can be marked as inheritable so they ripple to lower level directories.

• Fixed email username and password lengths
  There were a few minor problems with the lengths of the username and password fields for email authentication that could cause problems for some auth situations. The fields have been widened out to accomodate longer usernames including full domain names.

• wwIPStuff::cPriority added
  There have been a few changes with various headers and settings that have been moved out of the DLL and are now handled through cExtraHeaders that get set dynamically. So the Priority for example can now be set more easily.

• wwFTP::SetDirectory added
  You can now change directories on the server using wwFTP::SetDirectory. This makes it a little easier to browse directories.

• wwFTP::OnBufferUpdate now receives Total byte count
  The OnBufferUpdateMethod now receives a 4th parameter that holds the total size of the file to be sent or received. There's also a new cCurrentFileSize property that can be checked after a download or upload to check on size. This property is set only in FtpGetFileEx and FtpSendFileEx.

Version 4.55

This release is primarily a maintenance release that includes a number of minor fixes and patches as well as a few new requested features.

• Fixed email username and password lengths
  There were a few minor problems with the lengths of the username and password fields for email authentication that could cause problems for some auth situations. The fields have been widened out to accomodate longer usernames including full domain names.

• wwFTP::lPassiveFTP
  Allows you to easily set use of Passive FTP operation which provides much more reliable FTP connections over firewall connections.

• wwFTP::SetDirectory added
  You can now change directories on the server using wwFTP::SetDirectory. This makes it a little easier to browse directories.

• wwHttp::lCacheRequest
  Causes the current request to be cached or be retrieved from a cache. Useful for specific circumstances that retrieve static documents such as XML schemas or WSDL documents for example. Off by default.

• wwIPStuff InternetDial and InternetHangup
  You can now call these functions to bring up the Windows Internet Dialer which lets you choose a connection and dial it. This is an interactive interface only at this time.

• wwUtils::ContentTypeFromExtension
  Returns a content type for a given extension by looking up the value in the registry. Note that this only works for content types that are actually registered on the server, which may or not be in place. Very useful for client applications.

• wwUtils::MimeDateTime
  Converts a datetime value into a Mime formatted date like: Fri, 5 Jul 2002 00:59:01 -0700. Also converts Mime formatted dates back into DateTime values.

• wwIPStuff::cPriority added
  There have been a few changes with various headers and settings that have been moved out of the DLL and are now handled through cExtraHeaders that get set dynamically. So the Priority for example can now be set more easily.
