我使用SendMessage(hwnd,LB_GETTEXT,Index,Integer(@cbText));
可以获取没有图标的ListBox内容，如下图:

但去获取不到有图片的ListBox的内容，如下图:

在windowsx.h中有许多关于ListBox的方法，你可以尝试用这些方法来解决问题

请问能获取有图标的的ListBox里的内容吗？这段代码我在网络上看了很多次。

sorry，这我就不知道了，你可以到网上查查相关的资料，祝你好运

可以试试 WM_COPY 或许是hwnd找错了

hwnd应该没有错的，而且我可以获取其项数，就是获取不到其内容。

仍然非常感谢的你热情帮助，小生有所得罪之处万望见谅！

试了试是取不到

显示文字肯定要调用API的，如果能Hook到这个API我想就成了，但我不会Hook API。Knocker有这方面相关的资料不？
