全局代码如下：

Public Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs)

Dim axWebBrowser As Object = sender.ActiveXInstance

Dim refmissing As [Object] = System.Reflection.Missing.Value

Dim args As Object() = New Object(3) {}

args(0) = 24

args(1) = 2

args(2) = refmissing

args(3) = refmissing

axWebBrowser.[Gettype]().InvokeMember("ExecWB", 256, Nothing, axWebBrowser, args)

End Sub

 1、必须把预览的窗口关闭；

 2、或者把预览的路径换成别的路径或nothing。
