Dim postion1 As New Point

mouse_event(H1 Or H8000, postion1.X * 65535 / 1366, postion1.Y * 65535 / 768, 0, 0)

'按絕對(duì)位置移動(dòng)鼠標(biāo)

'在鼠標(biāo)坐標(biāo)系統(tǒng)中，屏幕在水平和垂直方向上均勻分割成65535×65535個(gè)單元，

'當(dāng)前所用顯示屏分辨率為1366*768

'所以要進(jìn)行如上轉(zhuǎn)換

mouse_event(H2, 0, 0, 0, 0) '鼠標(biāo)左鍵按下

mouse_event(H4, 0, 0, 0, 0) '鼠標(biāo)左鍵彈起

msdn上有 mouse_event 的詳解，大致使用如上

如何在VB.net中用程序控制鼠標(biāo)移動(dòng)和點(diǎn)擊

調(diào)用api

在Visual Baisc.net中的聲明：

Declare Sub mouse_event Lib "user32" (ByVal dwFlags As Long, ByVal dx As Long, ByVal dy As Long, ByVal cButtons As Long, ByVal dwExtraInfo As Long)

Public Const MOUSEEVENTF_LEFTDOWN = H2 '模擬鼠標(biāo)左鍵按下

Public Const MOUSEEVENTF_LEFTUP = H4 ’模擬鼠標(biāo)左鍵釋放

Public Const MOUSEEVENTF_MIDDLEDOWN = H20 '模擬鼠標(biāo)中間鍵按下

Public Const MOUSEEVENTF_MIDDLEUP = H40 '模擬鼠標(biāo)中間鍵釋放

Public Const MOUSEEVENTF_RIGHTDOWN = H8 '模擬鼠標(biāo)右鍵按下

Public Const MOUSEEVENTF_RIGHTUP = H10 '模擬鼠標(biāo)右鍵釋放

Public Const MOUSEEVENTF_MOVE = H1 '模擬鼠標(biāo)指針移動(dòng)

例：

mouse_event MOUSEEVENTF_LEFTDOWN,10,10,0,0

'在（10，10）模擬鼠標(biāo)左鍵按下

vb.net中,如何實(shí)現(xiàn)鼠標(biāo)在listbox控件上移動(dòng)時(shí),鼠標(biāo)所到的條目背景變黑、字變白；移開(kāi)后還原?

復(fù)雜的不會(huì)，來(lái)點(diǎn)兒簡(jiǎn)單的，借用在listbox里按下鼠標(biāo)時(shí)再移動(dòng)，會(huì)高亮顯示選擇行，并且會(huì)隨鼠標(biāo)移動(dòng)而變化的這一特點(diǎn)改進(jìn)的，不足之處是在listbox里，此時(shí)處于鼠標(biāo)左鍵在按下?tīng)顟B(tài)。
