【已解决】求助，退出代码: 3221226525，这个是什么报错呀？
本帖最后由 Cyydcc039485 于 2024-9-14 09:04 编辑我用autoit创建了一个listview，然后用C#程序获取listview中的项内容，程序执行到getitemtext时，autoit运行的程序自动退出了，退出代码：3221226525。请问下这个具体时什么报错呀？ 源代码呢???
二○二四年九月十一日 给出代码，让错误复现，才容易分析 程序代码

程序代码
你这个写法，获取当前进程的应该没有问题，获取其它程序的控件内容，你要在目标进程内申请空间，并把结构体和缓冲区写进去，发送消息后，在目标进程获取内容。 用下面的代码试试

用下面的代码试试
好的呢，我试试看
