WinBatch Control Manager Extender
Fixes and Improvements 

Keywords:  control manager extender updates new features   


Ver 44043 Sept 04, 2019
       
       Addressed an issue in the cWinInfo function that could sometimes 
       cause an extender memory allocation error when the passed in window
       handle is the handle to a child window that returns more than 16KB of
       text content.



Ver 44042 Aug 29, 2019
       
       Modified cWinInfo's request #0 to return an empty string instead of
       reporting an error when the window reports an invalid title/text
       length. 


Ver 44041 Feb 06, 2018
       
       Modified cWinidConvert function to no longer error when the 
       window associated with the supplied handle or id does not exist.  


Ver 44040 Feb 03, 2016

       Modified CWndInfo option 0, CFindByName, CwndByName, 
       cWndGetWndSpecName, and cWndByWndSpecName to prevent the rare
       occurance of the functions being unable to determine the correct 
       window text because the control or frame window is a custom 
       window.

       Added cSetWndSpecRetry function to control the cWndByWndSpec and 
       cWndByWndSpecName functions.  CSetWndSpecRetry changes the number 
       times the cWndByWndSpec and cWndByWndSpecName functions attempt
       to repeat the search for the window with the passed in specification.
       
       Modified most extender functions that incorporate repeated 
       attempts to obtain the requested information to detect user 
       requests for script termination via the control+break key 
       combination. Also reduced the number retries these function 
       attempt.  This change reduces delays caused when the function's 
       targeted window does not exist.



Ver 44039 June 29, 2011

       Added native 64-bit version of the extender for use with 64-bit WinBatch and WinBatch+Compiler.  


Ver 44038 Feb 14, 2010

       cWndByWndSpec and cWndGetWndSpec no longer cause a an access violation when machine performance counters are corrupt.
  


Ver 44037 Feb 11, 2008

       cClicktoolbar no longer send button clicks to button separators. Function does not 
       error but does return false to indicate that no message was sent.

       Added new function 'cGetCbSelText' which retrieves the selected text from a ComboBox 
       control.


Ver 20035  Jan 20, 2005

Ver 20023  Dec 13, 2000

      ROBOSCRIPTER Utility now included in the Control Manager
      extender.

      The Control Manager 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("wwctl32i.dll")
      should become
         AddExtender("wwctl34i.dll")


Version 20022  Nov 2, 2000

     Added new functions

     cGetLvFocText - returns text associated with a ListView 
                     item that has the focus.

     cGetLvDdtText - returns text associated with a ListView
                     item that is the drag and drop target.


Version 20020  Sept 13, 2000

     All &'s are ignored both when Window titles are specified
     in a function and when actual window titles are checked.
     This should not break any existing code, but make future
     code a little bit easier to write.  My recommendation?
     If the Window title has an &, use it in your function.


Version 20019  July 25, 2000

     Fixed one crashing bug with previous version of cSetWndtext.
