使用F1帮助（CHM格式）使用WPF [英] Using F1 Help (CHM format) With WPF

问题描述

我一直工作在一个WPF应用程序一段时间，时间已经到了CHM格式的帮助文档附加到它。

I've been working on a WPF application for a while, and the time has come to attach the CHM format help document to it.

但是，唉！ HelpProvider，显示Winforms中的CHM文件的标准方式，已经奇迹般地消失了，并在WPF中没有对应。我一直在试图使用WindowsFormsHost来产生一个新的控制，其实我可以显示帮助，但本质上它只是抓住整个用户界面的控制权。

But alas! HelpProvider, the standard way to show CHM files in Winforms, has magically vanished and has no counterpart in WPF. I've been trying to use WindowsFormsHost to spawn a new control so I can actually display the help, but essentially it just grabs control of the entire UI.

多一点细节：我已经得到了我想要，点击后打开CHM文件的菜单项。

A little more detail: I've got a menu item that I want to, when clicked, open up the CHM file.

首先，我成立了WindowsFormsHost ...

First I set up the WindowsFormsHost...

host = new System.Windows.Forms.Integration.WindowsFormsHost();
helpForm = new System.Windows.Forms.Control();
host.Child = helpForm;
host.Visibility = System.Windows.Visibility.Hidden;
this.grid1.Children.Add(host);

hp = new System.Windows.Forms.HelpProvider();
hp.HelpNamespace = "Somehelpfile.chm";
hp.SetHelpNavigator(helpForm, System.Windows.Forms.HelpNavigator.TableOfContents);

然后我说，瞧，彰显自己。

And then I say, voila, reveal yourself.

private void Help_Click(object sender, RoutedEventArgs e)
{
    host.Visibility = Visibility.Visible;
    helpForm.Show();
    hp.SetShowHelp(helpForm, true);
}

我真的不知道在哪里，从这里着手。当我展示helpForm，它掩盖了/重写现有的用户界面和我得到的是没有帮助文件灰色，空WPF窗口。

I'm not really sure of where to proceed from here. When I show the helpForm, it obscures / overrides the existing UI and all I get is a gray, empty WPF window with no help file.

任何考生？

推荐答案

叫我疯了，但你能不能只是做：

Call me crazy, but couldn't you just do:

System.Diagnostics.Process.Start(@"C:\path-to-chm-file.chm");
