systreeview32选中_读取sysTreeview32和SysListView32-优快云博客

本文链接：https://blog.youkuaiyun.com/weixin_42303616/article/details/111949912

这篇博客介绍了如何通过Windows API遍历并找到SysTreeView32和SysListView32控件，读取其选中项的文本内容。通过FindWindowEx函数定位窗口，然后使用SendMessage和ReadProcessMemory来获取和操作控件中的数据。示例代码分别展示了如何获取ListView的项目和TreeView的选定节点，并在发现特定文本时进行展开操作。
