关于SetCursorPos和WM_SETCURSOR的问题 [英] Question about SetCursorPos and WM_SETCURSOR

问题描述

看这个例子:

SetCursorPos(posX, posY)
sendmessage(hwnd, wm_rbuttondown, &H2, makelparam(posX,posY))
sendmessage(hwnd, wm_rbuttonup, 0, makelparam(posX,posY))

鼠标移动到该位置然后单击，但是我想找到一种模拟鼠标移动以单击的方式:

The mouse move to the location then click, but i want to find a way to simulate the mouse move to click like:

sendmessage(hwnd, WM_SETCURSOR, hwnd, ?)
sendmessage(hwnd, wm_rbuttondown, &H2, makelparam(posX,posY))
sendmessage(hwnd, wm_rbuttonup, 0, makelparam(posX,posY))

推荐答案

鼠标移动到该位置然后单击，但是我想找到一种模拟鼠标移动以单击的方式:

The mouse move to the location then click, but i want to find a way to simulate the mouse move to click like:

sendmessage(hwnd, WM_SETCURSOR, hwnd, ?)
sendmessage(hwnd, wm_rbuttondown, &H2, makelparam(posX,posY))
sendmessage(hwnd, wm_rbuttonup, 0, makelparam(posX,posY))

您是说您不知道该消息应该使用什么lParam吗?

Are you saying that you don't know what lParam should be for that message?

lParam低位字是命中测试代码，由WM_NCHITTEST消息的返回值定义
lParam高位字是引起该消息的鼠标消息的编号.

lParam low word is a hit test code as defined by the return values of the WM_NCHITTEST message
lParam high word is the number of the mouse message that caused the message.
