WebBrowser控件不会在Adobe中将Pdf文件显示到winform中.为什么? [英] WebBrowser control doesn't display the Pdf file into the winform with Adobe. Why?

问题描述

这是我的代码，用于将pdf文件打开到webBrowser控件中:

Here's my code to open the pdf file into the webBrowser control:

private void Form1_Load(object sender, EventArgs e)
    {
        OpenFileDialog dlg = new OpenFileDialog();
         dlg.Filter = "pdf files (*.pdf) |*.pdf;";
         dlg.ShowDialog();
         webBrowser1.Navigate(dlg.FileName);

    }

这是我的问题:

当我将Foxit Panthom用作默认pdf阅读器时，该pdf会显示在webBrowser中，但是当我将Adobe Reader(甚至尝试使用Sumatra Pdf尝试)设置为默认pdf阅读器时，该pdf文件会显示在一个单独的窗口中.为什么?我哪里错了?

When I have Foxit Panthom like default pdf reader the pdf is displayed into the webBrowser, but when I set Adobe Reader (I try even with Sumatra Pdf) to default pdf reader the pdf file is displayed into a separated window. Why? Where I'm wrong?

我正在使用32位Windows 7专业版.

I'm working with a Windows 7 Professional 32 bit.

推荐答案

在升级到Adobe Acrobat Reader DC后，它也停止为我们工作. 遵循此页面中的说明(意大利语；-) https ://helpx.adobe.com/it/acrobat/using/display-pdf-in-browser.html )对我们来说现在可以了.

It stopped working for us too after upgrading to Adobe Acrobat Reader DC. Following the instruction in this page (in italian ;-) https://helpx.adobe.com/it/acrobat/using/display-pdf-in-browser.html ) now is ok for us.

关闭电源，然后再次打开.

Switch off and then on again.
