Change Info
-------------------------------------------------------------------------------------

Version 25014   Aug 4 1998

      Initial public release


Version 25016    Aug 19 1998

      Fixed problem where full path of filename was not returned
      Fixed problem where the xxxFindNext was missing the first file.


Rev 25017 November 24, 1998 DRD

   Added the constant @FTPPASSIVE to the function iHostConnect.
   This allows passive ftp transfers.

   Return error:327 file not found, if user specifies "auto"
   iFtpDialog (option 2 or 3), and 0 for file size in the function
   iFtpGet, and the filename specified does not have proper case.


Rev 25030 April 7,1999 DRD

   MAJOR CHANGE:  Function parameters modified
   DLL renamed to wwint33I.DLL    (not 32I)

   iFtpFindInit wasn't properly checking file handles that were NULL.
   Fixes made to support long file names and file paths.
   Fixed iDialHangUp, only try to get the details of open connections
   if there are > 0 open.

   Fixed a problem where iDial was not returning proper last error
   information.

   iFtpOpen needed an additional flag to force a download of the
   requested file, object, or directory listing from the origin server,
   not from the cache.

   Revised iFtpFindInit and iLocFindInit, so we can handle long
   directory names by setting the 'current working' directories for
   the user.

   Added a parameter to iFtpFindinit. 'Match case' which allows the user
   the specify whether the mask should be case sensitive.

   Revised iFtpFindNext and iftpLocNext to match a long file name mask.

Rev 25031  July 14th, 1999   DRD

   Fixed 'Access violation' problem in iLocFindNext and iFtpFindNext
   if subdirectories exceeded 64K. We now reallocate the memory
   buffer as needed.

   Added fix for GPF caused by IE 4.0 bug. (if you attempt to set
   current directory w/ ftpSetCurrentDirectory and FtpFindFirstFile
   too many times it will crash. Apparently IE 5.0, doesn't have this
   problem.

Rev 25032  July 27, 1999   MHW

   Modifed iHttpOpen to handle UrlEncoded form data in addition to
   the multipart form data.

Rev 25033  July 29, 1999   DRD

   Documented iURLEncode and iUrlDecode.

   Added: function iContentUrl (url-data, keyword, value) 
   Formats a simple variable into encoded URL for a POST-type HTTP request.

Rev 25034  Aug 16, 1999   MHW

   Fixed iHttpOpen did not pass the desired headers in one case.

   Fixed problem with UrlEncoded Form Data and ihttp POST's.

Rev 25035  Aug 29, 1999   MHW

   Fixed iContentFile added new parameter(file type) and changed how
   file is read from _lread to FileRead.

Rev 25036  Aug 31, 1999   DRD

   Now returns error 306 bad handle if iOptionSet is given a
   bad handle. Need to use iOptionSet to set various parameters,
   immediately after iBegin (the function allocates and defines
   a top level handle for the other internet functions).

Rev 25037  Sept 16, 1999   DRD
   Added new function iReadDataBuff.
   Transfers data from an internet host to a binary buffer.

Rev 25038  Sept 24, 1999 DRD

   Fixed problem with iFtpOpen and @Binary

Rev 25039  Oct 12, 1999 DRD

   Fixed problem with iContentURL being called for more than one 
   set of form variables.

Rev 25040  Dec 14, 1999   DRD
 
   Fixed problem with the iFtpFindNext failing, if an *empty* directory
   was found in a mulitple directory recursive search.

   Added new functions (only available with MSIE 5 or newer)
   iGetConStatEx - retrieves the connected state of the specified internet connection.
   iFtpCmd - send commands directly to an FTP server.

Rev 25041 Jan 11, 2000

   Fixed GPF problems with iGetConStatEx and iFtpCmd

   Documented additional return values for iGetConState and iGetConStatEx


Rev 25042  Feb 4, 2000   DRD

   Fixed problem with iFtpFindNext not "seeing" files with no file root.

Rev 25043  Feb 17, 2000   DRD

   Fixed problem with iClose not sending ftp 'Quit' Command. We attempt
   to send ftpcommand for Quit if supported (IE5).
   Apparently problem in Wininet (IE4.0 & 5.0).

Rev 25044  March 20, 2000   DRD

   Fixed problem with iFtpPut and iFtpGet, not attempting to calculate filesize for
   progess bar, if user specified zero.

Rev 25055  Mar 29, 2000   MHW

   Fixed problem with iDial running under Win2000

Rev 25046  April 20, 2000   MW
   Added new  functions: iPing, iHost2Addr, and iAddr2Host.

Rev 25047  May 18, 2000  DRD MW
 
   Fixed problem with iClose and certain type of recursive directory searches
   where the iClose would cause an error.

Rev 25048 May 30, 2000 MW DRD

   and to only update dialog, if iDialog is specified.
   Fixed iFtpPut handling of FTP error 550.

Rev 25049 July 21, 2000 MW

   Fixed iReadDataBuf, which was not returning the entire file in some cases.


Rev 25050  Dec 14, 2000
   The WinInet extender has been updated to a new
   format to allow more descriptive function names and
   additional parameters.  This version of the extender
   requires WinBatch 2001A or newer to run.  This
   extender will not work on WinBatch 2000C or older.

   In addition, so as not to affect existing scripts using
   a previous version of this extender, the extender DLL
   has been renamed to include a 34I in the DLL name
   instead of a 32I.  Old and new versions of this
   extender can *usually* co-exist side by side.

   To use the new extender with old scripts and with
   WinBatch 2001A or newer you will need to change the
   AddExtender line in the script to reflect the new DLL
   name.   e.g.

   AddExtender("wwint33i.dll")
   should become
   AddExtender("wwint34i.dll")

Rev  25051 Jan 17, 2001 DRD

   Modified iFtpCmd, to accept the following commands:
   SMNT,TYPE,STRU,MODE,MDTM.

Rev  25052 March 29, 2001 DRD

   Modified iFtpFindNext, and iLocFindNext to handle reallocation
   of memory for large directory structures.

   Fixed hanging problem in iFtpFindNext, if directory was access
   denied while recursing.

Rev 25053 April 9, 2001 DRD

   Fixed a bug, missing slash before filename, in iFtpFindNext,
   introduced in 25052.

Rev 25054 June 22, 2001 DRD

   Fixed a bug, in iFtpFindInit, returning zero if path with 
   space was given.

Rev 25055 Septemeber 27, 2001 DRD
       Added a new function iWriteDatabuf. Which allows you to copy 
       chunks of a very large file to a FtpServer. 
       (Opposite of iReadDatabuf).

Rev 25056  Test build

Rev 25057 January 10, 2002 DRD
       Modified iFtpFindInit, to return zero, if a empty directory
       is passed and also deallocate memory,  if FindFirstFile fails
       (ie. if an empty directory is passed).

Rev 25058 January 11, 2002 DRD
       Modified iFtpFindInit, to check to see if there are any
       allocated buffers that need to be freed before allocating new 
       ones .  (Fixes a memory leak) 

Rev 25059 January 12, 2002 DRD
       Modified iClose, and iLocFindInit to try harder to free
       memory buffers to plug memory leaks when repeatedly
       using iFtpFindInit and iLocFindInit funtions.
 
Rev 25060 January 14, 2002 DRD
      Fixed problem where iGetLastError only ever seems to return an
      error code of 0 when there is something wrong while calling 
      iDial (i.e. telephone line unplugged). In addition if there is
      an existing connection iDial did not return the handle to this 
      connection as stated in the documentation, instead returning 
      FALSE (0).

      Modifications were made to iDial, iDialHangup, and iDialItemize.

      Fix: iDial, iDialHangup, and iDialItemize will now return error, 
      if unable to locate or load the RasApi32.dll or if not all the 
      necessary functions are available.
   
Rev 25061 April 8, 2002 DRD
      Modifications were made to iDialItemize, to return error if
       unable to enumerate ras entries.
      Made further modifications to iDial and iDialHangup to handle
      all Windows platforms.
      iContentUrl, value of a single form variable is nolonger
      limited to 1K, it has now been bumped up to 8K. 
  
Rev 25062 June 20, 2002 DRD
      Added new functions: iCookieGet,iCookieSet.

      Fixed problem with iDial hanging up right after its connected.

Rev 25064 Sept 16, 2002 DRD
      Fixed problem with iFtpFindInit not handling non-wildcarded
      file names properly.

Rev 25065 Oct 24, 2002 DRD/MW
      Fixed problem with the default accept type and added a new
      iHttpAccept function to deal with unusual cases.

Rev 20066 Oct 30, 2002 MW
      Modified progress bar for iFtpDialog to handle files greater than 40MB. 

Rev 20067 Dec 2, 2002 MW/DRD
       Fixed(?) a problem with iReadDataBuf returning the error
       12031:ERROR_INTERNET_CONNECTION_RESET.   

Rev 20068 April 2, 2003 DRD
       Fixed problem with display of FTP dialog. 
       Cancel button is now centered.

Rev 20069 April 16, 2003 DRD
       Added new flags: 'proxy_username' and 'proxy_password' 
       to iOptionSet and iOptionGet.

Rev 20070 May 21, 2003 DRD
        Fixed problem with display of iftpDialog. Status, source and 
        target items are now balanced.

   Fixed iHostConnect problem where if @HTTPS is specified and the function 
   failed it returned S0 (S-Zero), it now simply returns 0 (zero)

   Added new function iErrorDialog(handle, error)
         Displays a dialog box for the error that is passed to InternetErrorDlg,
         if an appropriate dialog box exists. 
         If the FLAGS_ERROR_UI_FILTER_FOR_ERRORS flag is used, the function 
         also checks the headers for any hidden errors and displays a dialog 
         box if needed.


         Parameters:
         (i) Handle - Handle to the Internet connection used in the call to 
                      iHttpOpen. 
         (i) Error - Error value for which to display a dialog box. This parameter
                     can be one of the following values.
                     Value Meaning 

                     12039 ERROR_INTERNET_HTTP_TO_HTTPS_ON_REDIR Notifies the user 
                           of the zone crossing to and from a secure site. 

                     12014 ERROR_INTERNET_INCORRECT_PASSWORD Displays a dialog box
                           requesting the user's name and password. (On Microsoft� 
                           Windows� 95 , the function attempts to use any cached 
                           authentication information for the server being accessed 
                           before displaying a dialog box.) 

                     12045 ERROR_INTERNET_INVALID_CA Notifies the user that the 
                           function does not recognize the certificate authority
                           that generated the certificate for this Secure Sockets 
                           Layer (SSL) site. 

                     12043 ERROR_INTERNET_POST_IS_NON_SECURE Displays a warning about
                           posting data to the server through a nonsecure connection. 

                     12038 ERROR_INTERNET_SEC_CERT_CN_INVALID Indicates that the SSL
                           certificate Common Name (host name field) is incorrect. 
                           Displays an Invalid SSL Common Name dialog box and lets 
                           the user view the incorrect certificate. Also allows the 
                           user to select a certificate in response to a server request. 

                     12037 ERROR_INTERNET_SEC_CERT_DATE_INVALID Tells the user that
                           the SSL certificate has expired. 

                     12044 ERROR_INTERNET_CLIENT_AUTH_CERT_NEEDED Displays a dialog
                           box requesting a client certificate. 


         Returns:
         (i) Returns @TRUE success, 
                     @FALSE failure, use iGetLastError() to one of the following values, 
                            or any other error value. 

                  Return Code Description

                  1223   ERROR_CANCELLED The function was canceled by the user. 

                  12032  ERROR_INTERNET_FORCE_RETRY This indicates that the function
                             needs to redo ts request. In the case of authentication 
                             this indicates that the user clicked the OK button. 

                  6      ERROR_INVALID_HANDLE The handle to the parent window is invalid. 

         Notes:


         This function checks the headers for any hidden errors and displays a dialog box, 
         if needed.
         
         Always inform the user when any of the following events occur:
         
         12039  ERROR_INTERNET_HTTP_TO_HTTPS_ON_REDIR
         1204   ERROR_INTERNET_INVALID_CA
         12043  ERROR_INTERNET_POST_IS_NON_SECURE
         12038  ERROR_INTERNET_SEC_CERT_CN_INVALID
         12037  ERROR_INTERNET_SEC_CERT_DATE_INVALID
         
         Unless the user has explicitly chosen not to be informed of these events, 
         failure to do so exposes the user involuntarily to a significant security risk.
         
         
         ERROR_INTERNET_CLIENT_AUTH_CERT_NEEDED Notes:

            If error 12044 ERROR_INTERNET_CLIENT_AUTH_CERT_NEEDED is specified,
            iErrorDialog must be called after iHttpOpen fails with the error 
            ERROR_INTERNET_CLIENT_AUTH_CERT_NEEDED (12044). iErrorDialog always
            returns ERROR_SUCCESS for ERROR_INTERNET_CLIENT_AUTH_CERT_NEEDED 
            regardless of whether you click OK or Cancel. Because iErrorDialog always 
            returns ERROR_SUCCESS, it may be tricky to determine if the user clicked Cancel.
            
            If Cancel is clicked, then a certificate is not sent. 
            If OK is clicked, the certificate is sent. 
            
            If the client certificate is not sent but the server requires it, 
            the server will return the 403 HTTP status code. You can query the status
            code by using the function iHttpHeaders, or checking the return value of 
            the iHttpOpen.
            
            if Cancel is clicked, you will receive error 403 on the second retry of
            iHttpOpen after iErrorDialog was called. 


        Added new function iParseUrl( url, flag, request)
         Breaks a URL into its component parts.

         Parameters
         (s) Url     the canonical URL to be cracked. 
         (i) Flags   controls the operation. This parameter can be one of the following values.

               Value       Meaning 
               0           No flags (default)
               268435456   ICU_DECODE - Converts encoded characters back to their normal form.
                                        This can be used only if the user provides buffers in
                                        the URL_COMPONENTS structure to copy the components into. 
               2147483648  ICU_ESCAPE - Converts all escape sequences (%xx) to their corresponding
                                        characters. This can be used only if the user provides
                                        buffers in the URL_COMPONENTS structure to copy the
                                        components into. 

         (i) Request	specifies which URL component is retrieved. 
               0 - Scheme name (for example, http, https, ftp, file)
               1 - HostName (for example, techsupt.winbatch.com)
               2 - UserName
               3 - Password
               4 - UrlPath (for example, /somewhere/something.htm or /somewhere/something.cgi). 
               5 - ExtraInfo (for example, ?something or #something). 

         Return 
         (i/s) specified request string, or 0 upon failure, 
                to get extended error information, call iGetLastError.
         
         Note: Do not use iParseUrl on file:// URLs that contain spaces, because the value
               returned is too large. This is only the case, however, with file:// URLs that
               contain space characters.


   Rev 25071 May 30, 2003 DRD
      Added new option "client_cert_context" to iOptionSet. If an application 
      receives ERROR_INTERNET_CLIENT_AUTH_CERT_NEEDED, use this option to 
      supply a certificate before retrying the request.
      
      Added new function iGetIEVer()
      Returns Internet Explorer's version string.
      
      Parameters:
      none
      
      Returns: 
      (s) 		version resource string

Rev 25072 July 8, 2003 DRD
         Modified iFtpFindNext to return file attributes if extended info is @true.   
         Removed all moderate level errors.   

         
Rev 25073 July 30th, 2003 DRD
        Modified iLocFindInit to handle relative file paths. iFtpFindNext nolonger
        changes the current working directory of the script. Also fixed problem with
        iFtpFindNext returning file paths with forward slashes. 

Rev 25074 Sept 26th, 2003 DRD

     Modified progress bar for iFtpDialog to handle files greater than
     40MB. (2G limit)

     Fixed 'percentage text' overlapping the progress bar in the
     iFtpDialog dialog.



Rev 44075 April 11th, 2005 DRD
   Added optional parameter to iFtpGet and iFtpPut to keep alive the connection.

   Removed 32k total string length limitation and removed 8k value limitation from iContentUrl.

   The WinInet extender has been updated to a new
   format to allow more descriptive function names and
   additional parameters.  This version of the extender
   requires	WinBatch 2004B or newer to run.  This
   extender will not work on WinBatch 2004A or older.
   
   In addition, so as not to affect existing scripts using
   a previous version of this extender, the extender DLL
   has been renamed to include a 44I in the DLL name
   instead of a 34I.  Old and new versions of this
   extender can *usually* co-exist side by side.
   
   To use the new extender with old scripts and with
   WinBatch 2004B or newer you will need to change the
   AddExtender line in the script to reflect the new DLL
   name.   e.g.
   
      AddExtender("wwint34i.dll")
   should become
      AddExtender("wwint44i.dll")


Rev 44076 June 30th 2005 DRD
   Removed handling of FTP error 550 in iFtpGet and iFtpPut. This should fix problem 
   where iFtpGet successfully retrieved the file but incorrectly returned 0 if the
   servers response contained the 550 error. 

Rev 44077 July 15th 2005 DRD

   Fixed iGetResponse to return proper last error information. Modified
   iFtpGet and iFtpPut to return the value 2 for probable success with 
   futher information.

Rev 44078 Sept 20th 2007
   iHttpOpen will now write last error information out the wwwbatch.ini. Two possible 
   keys are written out to the wwwbatch.ini: LastError and PreviousError. LastError gets 
   updated each time the function is called. Possible values are either �No Error�or the error 
   number that occurred along with the name of the function that failed. PreviousError contains 
   unmodified last error number and function name.

   iClose was modified to throw error 346: Pending Data - Requires iReadData or iWriteData, 
   if there is still data available to be read (i.e. iFtpCmd LIST command) .

   Fixed uninitialized string in iGetResponse. 
 

Rev 44079  Dec 16, 2008 DRF

   ADDED iFtpFileSize(conHandle, filename) 
   Retrieves the file size of the requested FTP resource.

   Parameters:
   (i) conHandle - Connection andle returned from a call to iHostConnect.
   (s) filename - name of the file to delete on the remote system . 
   
   Returns:
   (i) File size in bytes or -1 if file size is greater than 2 gigabytes. 
		 
   Note: iFtpFileSize currently only handles files files less than 2 gigabytes in size, 
   results unreliable if > the 2 gigabytes.


   If the scheme name ("http://" or "ftp://") is missing this function will return @FALSE and 
   iGetlastError will return 12006 (ERROR_INTERNET_UNRECOGNIZED_SCHEME).

   If the url specified does not exist this function will return @FALSE and 
   iGetlastError will return 12007 (ERROR_INTERNET_NAME_NOT_RESOLVED) The server name 
   could not be resolved.

   FIXED iClose not working properly if passed zero. Now iClose will return error 306 
   bad handle if passed a zero.

   FIXED iClose to only throw error 346: Pending Data - Requires iReadData or iWriteData, 
   if there is still data available to be read (i.e. iFtpCmd LIST command) .

   FIXED iGetReponse. Increased returned string size from 256 to 4096. 

   FIXED iFtpGet and iFtpPut to force values into iGetResponse.

   FIXED uninitialized string in first call to iGetResponse. iGetResponse now returns 
   the string 'NONE' if no error condition exists.

   iFtpDirMake will return the error 318: iFtpDir_ function failed if the function fails to create 
   the directory for any reason.

   WWWBATCH.INI is now placed in the [Application Data]\WinBatch\Settings directory, 
   instead of in the Windows directory. You can obtain the [Application Data] directory 
   using ShortCutDir function with the shell folder name 'AppData'.

   Added/updated WWWBATCH.INI error logging to the following functions:
	
	iAddr2Host
	iBegin
	iContentUrl
	iContentFile
	iCookieGet
	iCookieSet
	iDial
	iDialHangUp
	iDialItemize
	iGetConStatEx
	iGetIEVer
	iHost2Addr
	iFtpCmd
	iFtpDelete
	iFtpDirChange
	iFtpDirMake
	iFtpDirGet
	iFtpDirRemove
	iFtpFindInit
	iFtpFindNext
	iFtpOpen
	iFtpRename
	iHttpOpen
	iLocFindInit
	iLocFindNext
	iOptionGet
	iOptionSet
	iParseUrl
	iPing
	iReadData
	iReadDataBuf
	iUrlEncode
	iUrlDecode
	iWriteDataBuf

    Modified iFtpDirMake by removing 318: iFtpDir_ function failed error and return zero upon failure.

  Removed 318 error from iFtpDirRemove 

  iFtpFileExist(conhandle, ftppath, ftpfilename)
