[转]在WPF中打开网页方法总结

第三种方法：基本思路是使用Process.Start(“iexplore.exe”, ” www.msn.com.cn”)打开一个IE的窗口，然后再使用SetParent将该新窗口并入WPF的主窗口中。代码如下（其他函数声明见附录）：

代码　　　　 var process = Process.Start("iexplore.exe", " www.msn.com.cn");            process.WaitForInputIdle();              //让IE准备好            Thread.Sleep(3000);            var ieHandle = FindWindow("ieframe", null);            SetParent(ieHandle, this.Handle);            int style = GetWindowLong(ieHandle, GWL_STYLE);   SetWindowLong(ieHandle, GWL_STYLE, (style & ~WS_CAPTION));

具体的思路是：

Create a WindowsFormsHost and add it to a panel in your UI

Start the process (such as Notepad) using Process.Start

Call process.WaitForInputIdle

Use process.MainWindowHandle to get the window handle

Call SetWindowPos to set the process’s window to the coordinates and Z Order of the HwndHost window

Hook both the HwndHost and the process.MainWindowHandle to detect size changes and repeat step 5.
