使用 .NET WebBrowser 控件时,如何使用同一 session 在新窗口中打开链接(即,不要在服务器上启动新的 ASP.NET session ),或者如何捕获新的链接在同一 WebBrowser 控件中打开 URL 的窗口事件?
最佳答案
我只花了一个小时寻找答案,所以我想我会在这里发布结果。您可以使用SHDocVwCtl.WebBrowser_V1对象来捕获NewWindow事件。
注意:代码来自http://www.experts-exchange.com/Programming/Languages/Visual_Basic/Q_21484555.html#discussion
//-------------------------------VB.NET Version:-------------------------------
Dim WithEvents Web_V1 As SHDocVwCtl.WebBrowser_V1
Private Sub Form_Load()
Set Web_V1 = WebBrowser1.Object
End Sub
Private Sub Web_V1_NewWindow(ByVal URL As String, ByVal Flags As Long, ByVal TargetFrameName As String, PostData As Variant, ByVal Headers As String, Processed As Boolean)
Processed = True
WebBrowser1.Navigate URL
End Sub
//-------------------------------C# Version-------------------------------
private SHDocVw.WebBrowser_V1 Web_V1; //Interface to expose ActiveX methods
private void Form1_Load(object sender, EventArgs e)
{
//Setup Web_V1 interface and register event handler
Web_V1 = (SHDocVw.WebBrowser_V1)this.webBrowser1.ActiveXInstance;
Web_V1.NewWindow += new SHDocVw.DWebBrowserEvents_NewWindowEventHandler(Web_V1_NewWindow);
}
private void Web_V1_NewWindow(string URL, int Flags, string TargetFrameName, ref object PostData,string Headers, ref bool Processed)
{
Processed = true; //Stop event from being processed
//Code to open in same window
this.webBrowser1.Navigate(URL);
//Code to open in new window instead of same window
//Form1 Popup = new Form1();
//Popup.webBrowser1.Navigate(URL);
//Popup.Show();
}
关于.net - System.Windows.Forms.WebBrowser 在同一窗口或具有同一 session 的新窗口中打开链接,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/175836/
