How to get reference to PDF object embeded in IE

mLipok · September 17, 2015

I was allways wondering How to get reference to AcrobatReader object and after all to the PDF file embeded in IE.

Today I was here:

http://www.vitoplantamura.com/index.aspx?page=axvncviewer

there is such a interesting html:

<html>
<body>
<script language="JavaScript">
function rsChange ()
{
var ax = document.all.TestObj;
if ( ax.readyState == 4 )
{
if ( ax.IsInitialized == false )
{
window.setTimeout( "rsChange();", 100 );
}
else
{
ax.Server = "192.168.1.3";
ax.Connect ();
}
}
}
</script>
<OBJECT language='javascript' ID='TestObj' CLASSID='CLSID:36D64AE5-6626-4DDE-A958-2FF1D46D4424' WIDTH='640px' HEIGHT='480px' onreadystatechange='rsChange();'></OBJECT>
<br><br><br>
Don't forget to do a "REGSVR32 UltraVncAx.dll", before viewing this page.<br>
The timer trick in the rsChange() function is required to get the windowful ActiveX initialized properly, before letting the ActiveX create the VNC client child window.
</body>
</html>

When I analyze this then I start to wonder about this line:

var ax = document.all.TestObj;

EDIT: above fraction was only an introduction, describing where it came my question.

And now then the question arise :

How I can use document.all to get the refrence to specified AxObject in this Case I mean to AcrobatReader opened in IE ?

EDIT: of course I mean a case when I have opened document in IE.

What you think about ?

It's quite interesting, generally.

Thanks to Mod for moving this topic to Examples forum (I posted it in "Developer General Discussion").

mLipok - thanks for looking in to this.

Is there a way to use AutoIt Controls to fill in fields in the pdf which is in IE?

mLipok · September 20, 2015

I guess you are asking in relation to this:

I will back to this above topic soon.

I am using the free Foxit Reader. Your script generates a number of Unknown name COM errors, but embeds the

(Foxit?) object, loads and displays properly the PDF.

Great job, I can use this in my app :thumbsup:

mLipok · March 22, 2021

You have Commercial ActiveX component for Foxit Reader ?
Or you are just using :

https://www.foxitsoftware.com/pdf-reader/

?

Edited March 22, 2021 by mLipok

dmob · March 22, 2021

I'm using the free old version 7.4

mLipok · March 22, 2021

As I remember old version of FoxIt reader had exposed ActiveX interface, the current one needs commercial license, and maybe because of this fact I'm not able to get it works.
Current version of FoxIt Reader open PDF as default in windows, but in my script still AcrobatReader is used... interesting.

dmob · March 22, 2021

I am little confused, in my case at least... does this mean that IE object loads the default PDF handler?

It should but not in my case.... 🤔

dmob · March 22, 2021

It would be interesting to try it on a machine without Foxit or Acrobat installed. I'll try to find time....

mLipok · March 22, 2021

It could be interesting.

Danyfirex · March 25, 2021

I've tested in a machine without foxit or acrobat and it does not show the PDF file. It show as a download progress file and then request to open with a default pdf viewer in my case SumatraPDF. Of course it will not work because there is not any object registered/associated to .pdf like acrobat and foxit do.

Please check:

with Foxit Reader.

I will wait for your's response in Acrobat Reader - ActiveX Viewer.
