mouse_event()鼠标不动.米奇死了吗??? [英] mouse_event() Mouse does not move. Is mickey dead ???

问题描述

你好！

我的函数mouse_event()有问题.
我想将鼠标移到某个位置(例如x252 y87)，然后在该位置双击.
我输入的坐标是屏幕的绝对坐标.
如果我对msdn的理解正确，那么我首先必须将我的坐标(指的是1280 x 800像素的resulotion)转换为鼠标坐标".
我不明白为什么它失败了.读取了mouse_event行，但是鼠标没有移动.编译时都没有错误.我之前曾将mouse_event与标志"MOUSEEVENTF_MOVE"一起使用，但没有出现问题.
有人对我有提示吗?

问候

             keybd_event(VK_LBUTTON, VkKeyScan(VK_LBUTTON), KEYEVENTF_KEYUP, 0);//release Leftmousebutton
        }
        Places++;
    }
}

解决方案

尝试使用SendInput API代替，您可以为坐标提供左键按下标志，然后向其提供左键按下标志.

谢谢你戴夫！

SendInput()起作用了！

Hello !

I''m having a problem with the function mouse_event().
I would like to move the mouse to a certain place (eg x252 y87) and then doubleklick at that location.
My input coordinates are absolute screen coordinates.
If I have understood msdn right, I at first have to convert my coordinates (refering to a 1280 by 800px resulotion) to "mouse coordinates".
I do not understand why it fails. The mouse_event line is read, but the mouse does not move. No errors while compiling either. I have used mouse_event before with the flag "MOUSEEVENTF_MOVE" that did work without problems.
Anyone has a hint for me?

Regards
SH

        }
        Places++;
    }
}

解决方案

try using the SendInput API instead, you can provide the coordinates with a left button down flag followed by one with a left button up flag.

Thank You Dave!

SendInput() worked !
