I currently open a pdf in an iframe. The iframe is hidden and whenever the user hits the button, the iframe loads the pdf source. When the window closes, it removes the source.
The problem that I have is that when a person views the iframe, messes with the zoom and pages, then closes down the iframe, the next person is stuck with the work that the other person was doing. Is there a way I can reset a pdf back to the default zoom, page, orientation, etc?
I've been doing some testing and it seems that adobe has a cache that will cache the settings until the browser closes down. An example is go to
http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/pdf_open_parameters.pdf
Mess with the zoom and pages, go to a different web page, and when you go back to that url, you'll see it's the exact same as you left it. I assume that there is a setting that I have to set in adobe reader. I've also tried setting defaults with parameters, but that doesn't seem to be working.
This is for internet explorer 11.
Additional Info
this is for a kiosk system that is running IE11 in Kiosk mode. The shell has been replaced by ie, and it's set to load the site with the hidden iframe. The system is running Adobe Reader X 11.0 and I'm using the following to embed:
<object id="pdf" data="kill-charts.pdf" style="display: none;" width="100%" height="100%" type="application/pdf">
</object>
I've tried embed as well, but it doesn't make a difference. I swapped to object because I wanted to try with parameters. I tried this
<object id="pdf" data="kill-charts.pdf" style="display: none;" width="100%" height="100%" type="application/pdf">
<param name="zoom" value="100" />
</object>
but that didn't work after the second load.
If you look on the last page of the link you provided you will see that you can append #zoom=50 to the URL as follows:
http://example.org/doc.pdf#zoom=50
This will make the browser open it at 50% every time. You can also add other parameters as well such as page number:
http://example.org/doc.pdf#page=1&zoom=50
This method will work at least for the Adobe plug-in, but not guaranteed for other PDF plug-ins.

I have a VS2019 WinForm app with a form that contains a webbrowser control. The URL for the webbrowser control points to a form on my asp.net web site, HelpForm.aspx. The URL for HelpForm.aspx has args that the aspx page can use in the code file to make a database call with the args supplied to fetch text/html from a SQL Server database then apply that text/html as text to a label on the aspx page. That aspx page is then returned to my webbrowser control on my winForm. That all works fine. This allows me to use the same forms to retrieve different help data from the database.
As part of the text/html stored in the database some of the records contain code to embed a YouTube video. Here is an example of what is in the database:
'... The same is true if you use the mouse wheel while a combo box has the focus.
<object width="560" height="315"><param name="movie" value="https://www.youtube.com/embed/fpXX8mSuDV4"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="https://www.youtube.com/embed/fpXX8mSuDV4" width="560" height="315"></embed></object>
Note: There is a ....'
On some machines this works and the video appears inline with the text but on others I get a black box or a white box with a tiny icon in the upper left corner.
This seems to have something to do with IE/Edge but I cannot find anything useful to help fix this.
Any ideas ?? Thanks
The WebBrowser control is stuck in IE7 mode by default, unless you edit the registry on every computer where your application runs.
But even if you can edit the registry, you'll still be using Internet Explorer. And YouTube dropped all support for Internet Explorer back in March 2020.
Unfortunately, you're going to need to update your application to use a more modern browser control. For example, either CefSharp or WebView2 should work.
I have a flash object I need to embed on my tumblr blog (Billy's audio player) and the embed works fine, except that I need to click a white play button before the object works:
(this is in Chrome; there is a similar play button on Edge)
However, other websites don't have this play button over the widget, including the widget's own webpage and the bottom left of this blog.
This is the embed code, taken directly from the Billy's audio player webpage (with added newlines for readability):
<embed src="http://www.sheepproductions.com/billy/billy.swf?autoplay=true&f0=http://www.sheepproductions.com/sammy.mp3&t0=Sammy&total=1"
quality="high" wmode="transparent" width="200" height="10" name="billy"
align="middle" type="application/x-shockwave-flash" title="Adobe Flash Player">
Is there something I can add to make the flash object run automatically? I doubt it's a browser issue, as it works on some other webpages, and other viewers also see the white play button.
However, other websites don't have this play button... including the
widget's own webpage.
SWF and HTML must be in the same exact location (ie: web folder).
If SWF url is : http://www.sheepproductions.com/billy/billy.swf
then HTML must be : http://www.sheepproductions.com/billy/pageWithSWFembeded.html
This issue is caused by the small width/height of your SWF. Browsers assume it is a Flash advert banner and do not auto-load it. It can be fixed by either increasing SWF display size or by putting the small SWF in same location as HTML page that loads the SWF.
Also consider using HTML5 audio tag to guarantee playback of website audio even on mobile devices (they don't run Flash content within default browsers).
When the audio completes in the HTML5 version of the SoundCloud widget, the share panel appears and covers the audio waveform. The user can replay the audio; however, the share panel doesn't disappear, nor does there seem to be any way for the user to hide it. Nor is there any way to prevent the panel from appearing in the first place, which is the ideal option.
The "sharing" parameter is set to false in my embed code.
Here is the embed code I'm using:
<iframe width="100%" height="100%" scrolling="no" frameborder="no" src="https://w.soundcloud.com/player/?url=http%3A%2F%2Fapi.soundcloud.com%2Ftracks%2F87283114&buying=false&sharing=false&liking=false&show_artwork=false&download=false&show_user=false&show_bpm=false&show_playcount=false&show_comments=false&color=568ED4&theme_color=DDD9C3"></iframe>
Replicated in Firefox and Chrome.
Again, this is an HTML5 issue only. The Flash version works properly.
Note that a similar issue also occurred but was fixed in the Flash version:

We allow users of our application to embed a webpage containing a set of thumbnails into another third party webpage/blog etc. The embedding is done by using an object tag.
Each thumbnail provides an option to download original file. When user clicks on this option, the embedded content is disappearing in Safari 5.1.1 and Chrome 15.0 and instead "Could not render embedded content" is shown. Whereas FF 8.0 works correctly i.e. the embedded page stays there even after download, as it should.
The embed code we are using is like this -
<object data="http://myserver.com/em.aspx?e=FytXStk=" height="600" width="900" type="text/html">
<p>Could not render embedded content.</p>
</object>
Can anyone see what might be wrong here? Thanks.
I had to add target="_parent" for the download link. That did the trick.
Actually, if you just choose "Shockwave" instead of "Flash" from the drop down menu for video type, it all works perfectly.
Joomla Core Team has gotta do a better job on notifying developers and webmasters. It's obviously not obvious.
I'm trying to get an HTML page to run a shockwave-flash video. While I can do it no problem using:
<object width="350" height="263">
<param name="movie" value="video/star.swf">
<embed src="video/star.swf" width="350" height="263">
</embed>
</object>
IE will not run it without a two-stage verification that you want to do it. The little yellow line at the top of the page that you click on to select "Allow blocked content", and then after clicking on that it wants another confirmation in a dialog box warning you that active content will cause the Apocolypse.
Is there a way to get it to not do this? I could have sworn I have seen movies running on the web that don't do this kind of thing...
These warnings will pop up only when you load the page from local drive - not when you load the page from a server. And it's not just for flash - these warnings pop up even if you have some javascript in your page.
