获得在C＃里面插入面板网页浏览器错误 [英] Getting error on inserting webbrowser inside panel in c#

问题描述

我正在开发中，我需要插入panl.while内的一个网页浏览器做desginer码这里面我收到错误的应用程序无法获取web浏览器控制的窗口句柄。窗口的ActiveX控件不支持为此，我已经把代码后我得到的错误来运行它里面STSthread.but十字线。

i am developing an application in which i require to insert a webbrowser inside a panl.while doing this i am getting error inside desginer code "Unable to get the window handle for the 'WebBrowser' control. Windowless ActiveX controls are not supported."for which i have put the code to run it inside STSthread.but after that i am getting error of "cross thread.."

Thread newThread = new Thread(newThreadStart(MethodToCallCOMMethod));
newThread.SetApartmentState(ApartmentState.STA);
newThread.Start();
private void MethodToCallCOMMethod()
        {
            this.webBrowser1 = new System.Windows.Forms.WebBrowser();
            this.webBrowser2 = new System.Windows.Forms.WebBrowser();

            if (this.InvokeRequired)
            {
                this.BeginInvoke(new MethodInvoker(delegate
                                {
                                    this.p_bottom.Controls.Add(this.webBrowser2);

                                }));
            }
            else
            {
                this.p_bottom.Controls.Add(this.webBrowser2);
            }
        }

使用invokerequired后，我仍然得到跨线程错误： - 控制从另一个线程，它是用C＃创建的访问？，怎么解决呢..请帮助我。

after using invokerequired i am still getting "cross thread error:-control'' access from another thread that it was created in c#",how to solve it..?please help me.

推荐答案

问题是，你在不同的线程创建化网页浏览器，一般你不应该GUI线程之外创建或编辑控件。

The problem is that you are creating the WebBrowsers in a different thread, in general you should never create or edit controls outside the gui thread.

因此，无论创建webBrowser1和2个其他地方（在GUI线程），或者把MethodInvoker委托里面的代码（运行在GUI线程）

So either create the webBrowser1 and 2 somewhere else (in the GUI Thread) or put the code inside the MethodInvoker delegate (which runs in the GUI Thread)

如果它说当前线程不在单线程单元那么无论你的主要功能并不像这样（东西VS默认创建），或试图从另一个线程创建它们：

If it says the current thread is not in a single-threaded apartment then either your Main function doesn't look like this (what VS creates by default) or you tried to create them from another thread:

[STAThread]
static void Main()
{
    Application.EnableVisualStyles();
    Application.SetCompatibleTextRenderingDefault(false);
    Application.Run(new Form1());
}
