关于网页控件等待问题 发帖心情

Post By：2014/9/23 15:18:00 [只看该作者]

需要等待打开网页后，然后点击网页一点地方（点击自动播放视频)，我现在问题是等待网页转载，需要等待几秒时间。

我用的是 Threading.Thread.Sleep(2000) ，问题是这个线程把网页装载和点击都做了延迟。而我需要等待网页完成后，

自动点击。有好办法吗？

Dim brw As WinForm.WebBrowser = e.Form.Controls("WebBrowser1")

brw.Address = "http://www.baidu.com" '随便啊

Const MOUSEEVENTF_MOVE As Int32 = &H1 ' mouse move

Const MOUSEEVENTF_LEFTDOWN As Int32 = &H2 ' left button down

Const MOUSEEVENTF_LEFTUP As Int32 = &H4 ' left button up

Const MOUSEEVENTF_RIGHTDOWN As Int32 = &H8 ' right button down

Const MOUSEEVENTF_RIGHTUP As Int32 = &H10 ' right button up

Const MOUSEEVENTF_MIDDLEDOWN As Int32 = &H20 ' middle button down

Const MOUSEEVENTF_MIDDLEUP As Int32 = &H40 ' middle button up

Const MOUSEEVENTF_ABSOLUTE As Int32 = &H8000 ' absolute move

Const MOUSEEVENTF_WHEEL As Int32 = &H800 ' wheel button rolled

Threading.Thread.Sleep(2000)

SetCursorPos (599, 589) '鼠标位置

mouse_event( MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0) ‘点击

mouse_event (MOUSEEVENTF_LEFTUP, 0, 0, 0, 0)

有点甜
