在 MS Windows(XP) 上使用来自不同进程的窗口句柄进行窗口操作 [英] Window manipulation using window-handle from different process on MS Windows(XP)
问题描述
是否可以对来自其他进程的窗口进行一些操作?我想做的是:- 去除窗户装饰- 将窗口移动到屏幕的任意位置- 让窗口保持在顶部而不使其模态
指向命令行工具、脚本或 C/C++ 代码片段的链接最好.
非常感谢!
我决定再试一次,所以我尝试了你的代码并添加了缺少的东西:一个 -naked
选项.>
去除装饰的关键从这里来.虽然它有效,但您最终会发现裸露的应用程序可能会在此之后开始显示一些错误.

Is it possible to do some operations with a window from other process having it's handle? What I would like to do is: -remove window decoration -move window to any position of the screen -let window stay on top without making it modal
A link to a command line tool, script or C/C++ code snippet be great.
Thank you very much!
I decided to take another shot, so I experimented with your code and added what was missing: a -naked
option.
The key to remove the decoration came from here. Though it works, you will eventually find out that the application who got naked might start displaying a few bugs after it.
