显示PDF成为焦点并使用热键 [英] Display PDF Takes Focus and Eats Hot Key

问题描述

我在SO上发现的使用的代码可以通过WindowsFormsHost中的主机使用基于COM的Acrobat Reader来显示PDF.

Used code I found on SO to use the COM based Acrobat Reader to display PDF via hosting in a WindowsFormsHost.

它显示PDF格式.两个问题:

It displays the PDF fine. Two problems:

• 当我加载PDF时，控件AxAcroPDFLib.AxAcroPDF成为焦点

• When I load the PDF the control AxAcroPDFLib.AxAcroPDF takes focus

我希望焦点保持在先前的

I want focus to remain on the prior

当AxAcroPDFLib.AxAcroPDF专注时，它会吃掉热键(N)

When AxAcroPDFLib.AxAcroPDF has focus it eats the Hot Key (N)

ALT键甚至不会在N下划线.即使用户选择了AxAcroPDFLib.AxAcroPDF，我也希望热键能够正常工作.

The ALT key does not even underline the N. Even if the user selects the AxAcroPDFLib.AxAcroPDF I would like the Hot Keys to work.

我了解这是WPF中的COM和Adobe，可能没有答案.如果有免费或廉价的WPF控件来查看PDF，我很乐意走这条路.这是用于商业应用程序，因此必须免费(或便宜)用于商业用途.

I understand this is COM and Adobe in WPF and there may not be an answer. If there is a free or cheap WPF control to view PDF I would be happy to go down that path. This is for a commercial application so it has to be free (or cheap) for commercial use.

 <Button  Click="Button_Click">_Next</Button>     

 <WindowsFormsHost Name="windowsFormsHost1"  Margin="1" />

 UserControl1 UC = new UserControl1(@"C:\temp\1000001.pdf");
 this.windowsFormsHost1.Child = UC;


 public UserControl1(string filename)
 {
     InitializeComponent();
     this.axAcroPDF1.LoadFile(filename);
 }

这确实显示PDF.在生产应用程序中，我根据使用的操作显示各种PDF.

This does display PDF. In the production application I display various PDFs based on used actions.

推荐答案

汉斯所说的话. Acrobat似乎正在吃键盘按键，对此我无能为力.

What Hans said. Acrobat appears to be eating key strokes and there is nothing I can do about it.
