我的VBForm中有一个webbrowser控件。 它在我的网站上查找并显示它。

WebBrowser1中有表单提交按钮。 我希望它是这样的,当他们点击WebBrowser1网页上的一个按钮时,它将打开自己的浏览器来提交表单

我该怎么做?

(是的,这是我的网站。如果需要,我可以更改服务器上的HTML。)

答案 0 :(得分:1)

答案归功于:Opening default web browser 并且:vb.net WebBrowser links to Default Web Browser

和一些反复试验。工作结果如下:

Private Sub WebBrowser1_Navigating(ByVal sender As Object, ByVal e As System.Windows.Forms.WebBrowserNavigatingEventArgs) Handles WebBrowser1.Navigating
    'added a match string - if Allow is inside the URL link, then the WebBrowser control is allowed to navigate to it. otherwise use their browser.
    dim Allow as string = "http://mysite.com"
    If InStr(e.Url.ToString(), Allow) = 0 Then
        ' I'm trying here to cancel the event so that the WebBrowser1 control doesn't go there.
        e.Cancel = True
        ' then start a new process with their default browser
        System.Diagnostics.Process.Start(getDefaultBrowser(), e.Url.ToString())
    End If
End Sub

Private Function getDefaultBrowser() As String
    Dim browser As String = String.Empty
    Dim key As RegistryKey = Nothing
    Try
        key = Registry.ClassesRoot.OpenSubKey("HTTP\shell\open\command", False)

        'trim off quotes
        browser = key.GetValue(Nothing).ToString().ToLower().Replace("""", "")
        If Not browser.EndsWith("exe") Then
            'get rid of everything after the ".exe"
            browser = browser.Substring(0, browser.LastIndexOf(".exe") + 4)
        End If
    Finally
        If key IsNot Nothing Then
            key.Close()
        End If
    End Try
    Return browser
End Function

如果Martin Parkin没有发布重复警告,我永远不会解决它。

还 - 必须更改我的METHOD = GET链接,帖子标题并不总是以这种方式翻译。
