自动化测试工具WinMacro解析


在codeproject上找到一个project名字是WinMacro。
具体实现是使用了SetWindowsHookEx函数。
SetWindowsHookEx(WH_GETMESSAGE,GetMsgProc,hinstance,0),设置了一个操作系统级钩子,主要是为了获得WM_CANCELJOURNAL消息。在MSDN的JournalPlaybackProc帮助里说

If the user presses CTRL+ESC OR CTRL+ALT+DEL during journal playback, the system stops the playback, unhooks the journal playback procedure, and posts a WM_CANCELJOURNAL message to the journaling application

录制动作使用的是SetWindowsHookEx(WH_JOURNALRECORD,JournalRecordProc,hinstance,0),存到一个文件里。回放动作使用了这个函数SetWindowsHookEx(WH_JOURNALPLAYBACK,JournalPlaybackProc,hinstance,0)。WinMacro代码里面有一些技巧就是加速回放,具体可以看code。项目地址:http://www.codeproject.com/tools/winmacro.asp

Functions

SetWindowsHookEx Function

The SetWindowsHookEx function installs an application-defined hook procedure into a hook chain. You would install a hook procedure to monitor the system for certain types of events. These events are associated either with a specific thread or with all threads in the same desktop as the calling thread.
