- The spy program and dynamic link library, is a sample application that
- hooks the HK_INPUT and/or HK_SENDMSG hooks, and spys on what messages
- are sent to which window.
-
- The application currently has two threads:
- 1) The main thread controls the user interface.
- 2) The second thread waits for messages from the hooks.
-
- This tool is very useful for debugging, and looks up symbols
- from symbol files with the "Spy...List Near Symbol..." selection.
- This is "context sensitive" -- given the appropriate PID, you can
- identify symbols given that context. For example, you could run
- another application, look at the window for that application
- (using the Windows...Window List... option), get the window's PID,
- and perhaps print out where in the window procedure you are (by
- looking in the Pfnwp: field).
-
- Note: Since the "List Near Symbol" dialog box is modeless, you can move
- it off to the side while you work on something else (although its position
- is saved relative to the SPY main window).

- spyhook.h - include file gets copied to ..\include
- spyhook.lib - import library gets copied to ..\lib (and deleted)
- spyhook.dll - dynamic link library gets copied to ..\dll (and deleted)
-
- Note: This application needs "selector.h", which should be in ..\include.
-
- Bugs: Spy...List Near Symbol produces a dialog box with a size border.
- However, the controls are not always redrawn as expected if you
- change the size of the dialog box.
