权限被拒绝:无法远程调用非公共或静态方法 [英] Permission denied: cannot call non-public or static methods remotely

问题描述

好的，我已经在此处找到了针对此特定错误消息的解决方案.但我的情况略有不同.我的代码中没有非公共"或静态"方法.都是公开的.我想要做的是将在一个进程中创建的 FrameworkElement(更具体地说是 Web 浏览器控件)传递给另一个进程以供显示和使用.此外，我没有使用(并且会避免使用)任何框架 3.5 插件.

Ok I've found a solution to this particular error message on here already. But my case is slightly different. There are no "non-public" or "static" methods in my code. All are public. What I'm trying to do is pass a FrameworkElement (more specifically a web browser control) that was created in one process over to another process for display and use. Also I'm not using (and would to avoid using) any of the framework 3.5 addin stuff.

每次都在下一行失败.

<代码>fe = FrameworkElementAdapters.ContractToViewAdapter(tab.ReturnBrowserObject)

tab.ReturnBrowserObject 返回一个 INativeHandleContract，上面的行应该将其转换为 FrameworkElement.

tab.ReturnBrowserObject returns an INativeHandleContract which the above line is suppose to convert to a FrameworkElement.

代码来自宿主进程的相关代码.

推荐答案

好的，我终于让它工作了.虽然不是我最初的打算.关键是 Win32 API SetParent.浏览器控件是在辅助进程中创建的，并重新指向主进程的窗口.唯一需要解决的问题是尺寸.

Ok so I got it working finally. Though not how I originally was going about it. The key is the Win32 API SetParent. The browser control is created in the secondary process and the re-parented to the primary process's window. The only issue left to solve is sizing.
