+Windows 界面自动化工具使用说明
+==========================
+
+基本语法:
+sendmessage.exe -type <操作类型> [参数...]
+
+操作类型:
+--------
+1. keyboard - 键盘操作
+2. mouse   - 鼠标操作
+3. inspect - 获取控件树
+
+通用参数:
+--------
++-method    窗口查找方式（可选，默认title）
++          可选值：title（标题）, handle（句柄）, active（活动窗口）
++
+-window    窗口标题或句柄（支持模糊匹配）
+-control   控件类名
+-background 后台操作，不激活窗口，默认激活
+
+键盘操作参数:
+-----------
+-action    操作类型：keys（按键）或text（文本）
+-value     要发送的按键或文本内容
+
+鼠标操作参数:
+-----------
+-action    操作类型：click（单击）、doubleclick（双击）、rightclick（右键）
+-text      控件文本
+-pos       点击坐标（x,y）
+
+控件树参数:
+---------
+-filter    过滤条件（控件类名或文本）
+
+使用示例:
+--------
+1. 发送按键到指定窗口：
+   sendmessage.exe -type keyboard -action keys -window ""记事本"" -value ""ctrl+a""
+
+2. 发送文本到指定控件：
+   sendmessage.exe -type keyboard -action text -window ""记事本"" -control ""Edit"" -value ""Hello World""
+
+3. 点击指定控件：
+   sendmessage.exe -type mouse -action click -window ""记事本"" -control ""Button"" -text ""确定""
+
+4. 后台发送文本：
+   sendmessage.exe -type keyboard -action text -window ""记事本"" -value ""Hello"" -background
+
+5. 获取窗口控件树：
+   sendmessage.exe -type inspect -window ""记事本"" -filter ""button""
+
+6. 使用句柄查找窗口：
+   sendmessage.exe -type keyboard -method handle -window ""0x12345"" -value ""Hello""
+
+7. 操作当前活动窗口：
+   sendmessage.exe -type keyboard -method active -value ""ctrl+s""
+
+注意事项:
+--------
+1. 窗口标题支持模糊匹配
+2. 控件类名需要完全匹配
+3. 后台操作可能会影响某些程序的响应
+4. 建议先用inspect获取正确的控件信息再进行操作
+5. handle方式查找窗口时需要提供正确的窗口句柄
+6. active方式不需要提供window参数，直接操作当前活动窗口
