MessageHistory 2.0

MessageHistory for 32-bit and 64-bit platforms has been extended and improved to make it better for troubleshooting and debugging GUI. What’s new in this version:

  • Added more filtering to reduce log size for default options
  • Shows names for messages sent to the following controls:
    • edit
    • static
    • button
    • listbox
    • combobox
    • scrollbar  
  • Added Spy++-style log for bulk messages sorted by time
  • Easter egg (hold <Shift> key and click on About button) 

It can be downloaded from Citrix support web site.

The picture from my recent presentation shows schematically the difference between sent and posted messages:  

and the following diagram depicts relationship between processes, threads and windows:
