　　 某些网页出于各种考虑会弹出对话框要求信息确认，往往会中断我们的webbrowser过程，可以使用如下方法：
　　1.加入Microsoft Html Object
　　2.加入语句
　　Private Sub WebBrowser1_NavigateComplete2(ByVal pDisp As Object, URL As Variant)
　　Dim obj As HTMLDocument
　　Set obj = pDisp.Document
　　obj.parentWindow.execScript "function showModalDialog(){return;}" '对showModalDialog引起的对话框进行确定
　　End Sub
　　而confirm引发的对话确定框可用confirm替换showModalDialog即可，Alert等同理~另一种方法在CSDN看到的方法，过个记录（未尝试）
　　Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long ShellExecute frmDisplay.hwnd, vbNullString, "http://www.sina.com", vbNullString, vbNullString, SW_SHOWNORMAL

　　我使用间隔n秒后发送sendkey"{enter}"能实现,但是这样太垃圾了
　　有什么直接控制的方法吗?
　　这个问题我已经研究清楚了,使用findwindow,findwindowex,sendmessage,再加time实现了
　　下面是代码,大家共享
　　Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
　　Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
　　Private Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As String) As Long
　　Private Const BM_CLICK = &HF5
　　Private Sub Timer2_Timer()
　　pk = FindWindow(vbNullString, 对话框名) '查找窗体，就是警告对话筐
　　pp = FindWindowEx(pk, ByVal 0&, "Button", 按钮名) ' 查找指定窗题上的指定button
　　SendMessage pp, BM_CLICK, 0, 0 '给button发送按下消息
　　End Sub 
　　Private Sub WebBrowser1_NewWindow2(ppDisp As Object, Cancel As Boolean)
　　Cancel = True
　　End Sub 
　　哪有那么麻烦：
　　Private Sub WebBrowser1_NavigateComplete2(ByVal pDisp As Object, URL As Variant)
　　Dim oDoc1 As HTMLDocument
　　Set oDoc1 = pDisp.Document
　　oDoc1.parentWindow.execScript "function alert(){return;}"
　　oDoc1.parentWindow.execScript "function confirm(){return;}"
　　oDoc1.parentWindow.execScript "function showModalDialog(){return;}"
　　End Sub 
　　晕.那么多答案没一个有用的.我遇到过.LZ把这两个事件加进去就行了
　　Private Sub WebBrowser1_DownloadBegin()
　　WebBrowser1.Silent = True
　　End Sub
　　Private Sub WebBrowser1_DownloadComplete()
　　WebBrowser1.Silent = True
　　End Sub
