Ie.au3 T2.0 Internet Explorer Automation Library

DaleHohm · May 24, 2006

@DaleHohm
I was interested in making a Embedded IE object that needs to run a Java Applet in it.
I know you created this function to add a eventscript to the HEAD. _IEHeadInsertEventScript()
But is there a way (or better an example) on how to add it to the BODY.
The script needs to run when opening the AutoIT Gui.
In my signature you can find the MailEncoder Gui. Something like that but the content should run a Java Applet.
Thanks in advance

@ptrex

Remember the addage that the only similarity between Java and Javascript is the first 4 letters (and not even that when you know that Javascript is really ECMAScript).

You can embed your Java applet in the body of your HTML page by 1) reading the HTML with _IEBodyReadHTML() 2) inject your <applet> or <object> tags into the source and 3) write the HTML back out with _IEBodyWriteHTML()

@darkfriend

If you saw the workaround then you also saw the reason it is what it is... after a _IEFormSubmit() you'll need to manage calls to _IELoadWait yourself... you'll want to wait for the browser, then the frame. E.g.

_IEFormSubmit($oForm, 0)

_IELoadWait($oIE)

_IELoadWait($oFrame)

You should then be ok without having to modify the UDF.

Dale

Update: ugh. the frame presents itself as a window object - window objects don't have a readyState... there is still a window for error. I need to look deeper.

Hi,
i had the same error with the FormSubmit function...which calls a _IELoadWait,
i tryed the work around
in removing the Do...until (func: IELoadWait)
where it crashes
C:\Program Files\AutoIt3\beta\Include\IE.au3 (709) : ==> The requested action with this object has failed.:
Until ($oTemp.document.readyState = "complete" Or $oTemp.document.readyState = 4)
Until ($oTemp.document.readyState ^ ERROR
it worked not to bad...
after i saa the work around here in the forum
_IEFormSubmit($o_form, 0)
_IELoadWait($oIE)
but it failed often and went forward to a parsing step in my programm even if the site wasen't loaded.
im now at the Point where i implementet again the IELoadwait without the Do until where it crashed and
added a Sleep(2000) ...
_IEFormSubmit($o_form)
_IELoadWait($oIE)
Sleep(2000)
this works normally but it makes access really slow, is there a way to fix the IELoadWait to get optimal performance of waiting on the loaded frameset...?
Thank you for ur Help...sry bad english ...

You can embed your Java applet in the body of your HTML page by 1) reading the HTML with _IEBodyReadHTML() 2) inject your <applet> or <object> tags into the source and 3) write the HTML back out with _IEBodyWriteHTML()

Thanks for the feedback.

But I was hoping to make an on the fly HTML page with an applet.

This is more complicated I know, but that's why I am asking some advise.

I thuoght of using these functions.

_IECreateEmbedded() = to creade the Objects

_IEEmbed = To show in AutoIT

_IENavigate ( $oIE, "about:blank" ) = to create the blank page in the object

_IEDocWriteHTML ( $oIE, "<body> = The on the fly creation of the HTML page

So far so good.

But If I include the <Applet> in the <Body> how does it show ? Because the Applet need to get to the internet to get it's data.

So once I have loaded the HTML page in the IE Object including the Applet, what' s next ?

I had expected the following to work:

#include <IE.au3>
$sHTML = _
    '<APPLET CODEBASE="http://java.sun.com/applets/other/Bubbles/classes"' & _
    'CODE="Bubbles.class" WIDTH=500 HEIGHT=500 ALIGN=MIDDLE>' & _
    '<P><IMG SRC="bubbles.gif" ALT="[GIF image (2k)]"><BR>' & _
    'An extract from a snapshot of <CITE>Bubbles</CITE> animation' & _
    'by <A HREF="http://java.sun.com/">java.sun.com</A>.</P>' & _
    '</APPLET>'
$oIE = _IECreate()
_IEBodyWriteHTML($oIE,$sHTML)

Everything looks correct, but the applet doesn't start. Right now I cannot explain it.

maybe... ???

$sHTML = _
    '<APPLET CODEBASE="http://java.sun.com/applets/other/Bubbles/classes"' & _
    'CODE="Bubbles.class" WIDTH=500 HEIGHT=500 ALIGN=MIDDLE>' & _
    '<P><IMG SRC="bubbles.gif" ALT="[GIF image (2k)]"><BR>' & _
    'An extract from a snapshot of <CITE>Bubbles</CITE> animation' & _
    'by <A HREF="http://java.sun.com/">java.sun.com</A>.</P>' & _
    '</APPLET>'
$oIE = _IECreate()

_IEnavigate($oIE, "about:blank")


_IEBodyWriteHTML($oIE,$sHTML)

DaleHohm · May 25, 2006

Hmmm... I don't think so... _IECreate() actually navigates to "about:blank" it you don't pass a URL and also does an _IELoadWait() to insure it completes. I tried your addition just insure I wan't missing anything, but the result is identical.

_IEDocReadHTML() shows that everything is there and loaded properly... the same code saved to an .htm file and opened serperately works as expected.

You can tell that the applet is actually rendered (righ-click in the upper-left region of the page where the applet would be and you get no context menu... move down and right and you get the menu).

The appllet simply doesn't start running...

DaleHohm · May 26, 2006

Anyone do a lot of work in Java that might know how to troubleshoot this?

I changed the test a little... now looks like this:

#include <IE.au3>
$sHTML = _
'<HTML><HEAD><TITLE>Bubbles</TITLE></HEAD><BODY>' & _
'<APPLET ' & _
'CODEBASE="http://java.sun.com/applets/other/Bubbles/classes" ' & _
'CODE="Bubbles.class" WIDTH=500 HEIGHT=500 ALIGN=MIDDLE>' & _
'</APPLET>' & _
'</BODY></HTML>'
$oIE = _IECreate()
_IEDocWriteHTML($oIE,$sHTML)

In the Java console I see this:

basic: Registered modality listener
liveconnect: Invoking JS method: document
liveconnect: Invoking JS method: URL
basic: unknown protocol: about

When I run it in a stand-alone browser from disk it works and I see this in the console:

basic: Registered modality listener
liveconnect: Invoking JS method: document
liveconnect: Invoking JS method: URL
basic: Referencing classloader: sun.plugin.ClassLoaderInfo@dfcb47, refcount=1
basic: Added progress listener: sun.plugin.util.GrayBoxPainter@1342545
basic: Loading applet ...
basic: Initializing applet ...
basic: Starting applet ...

Any guesses about the "unknown protocol: about" ??

Dale

DaleHohm · May 26, 2006

Any guesses about the "unknown protocol: about" ??

A-Ha! the page we are on is navigated to "about:blank". It is somehow reading that URL and interpreting the about: as a protocol (like http:). At least it is a starting point...

DaleHohm · May 26, 2006

Ok ptrex, this works. The about:blank issue appears to be a JAVA plugin bug. This workaround requires a blank file on disk, but you can actually attach to any valid URL. What a waste of time, but I feel vindicated.

#include <IE.au3>
$sHTML = _
    '<HTML><HEAD><TITLE>Bubbles</TITLE></HEAD><BODY>' & _
    '<APPLET ' & _
    'CODEBASE="http://java.sun.com/applets/other/Bubbles/classes" ' & _
    'CODE="Bubbles.class" WIDTH=500 HEIGHT=500 ALIGN=MIDDLE>' & _
    '</APPLET>' & _
    '</BODY></HTML>'
$oIE = _IECreate("c:\blank.htm")
_IEBodyWriteHTML($oIE,$sHTML)

@DaleHohm

Thanks very, very much. Your the man

You can imagine if you as an expert, didn't quite know how to get it to work.

Imagine how much time I would have needed to get it rolling. If I ever would have got it rolling ?

Anyhow if it works out I will give you something (an Embedded Customizable World Clock) in return.

Sorry DaleHohm I ran your example and all I get to see is a blank page after ActiveX warnings, in an IE browser.

No applet there

Does the blank.htm page need any contents ? I just opened Notepad and save it as a Blank.htm ?

I see I left some extra baggage in the string, so you may want to try again. I don't expect it to be a different result however.

You should also try placing just the HTML in a file and open it. I suspect you'll find issues with JAVA configuration.

Also, using a local class file would be less complex than the CODEBASE I used.

#include <IE.au3>
$sHTML = _
    '<APPLET ' & _
    'CODEBASE="http://java.sun.com/applets/other/Bubbles/classes" ' & _
    'CODE="Bubbles.class" WIDTH=500 HEIGHT=500 ALIGN=MIDDLE>' & _
    '</APPLET>'
$oIE = _IECreate("c:\blank.htm")
_IEBodyWriteHTML($oIE,$sHTML)

Dale

Edit: and yes, blank.htm was simply an empty file.

No success yet.

But I'll fiddle around some and see how far I get.

Thanks !!

Using the workaround, anything that you can get to work in a logcal HTM file you open with the browser should work.

Updated to T2.0-2 (see basenote). I expect this to be very stable.

Please beat this up -- we are trying to get it into the production UDF release!

Dale

P.S. I did NOT have to remove the _IELoadWait from _IEFormSubmit as I had threatened.

Sure. The error is probably in the _IEFormElementGetObjByName statement as it's implemented (not your fault).

I had this problem with IE_T2.0_2.au3 and downgraded to IE_T2.0_1.au3 and it instantly went away. No other code or version changes necessary.

So drop down a version and see how you go.

Wouldn't it just be a matter of using the ComErrorHandler function to capure these errors ?

No. The error is in the IE.au3 library, not in the users code.

If you can replace the version of the IE.au3, make zero changes to the user's code but suddenly your code works, then there's a problem with the libary (I'm not aware that the _IEFormElementGetObjByName function is deliberately behaving differently). There shouldn't be an error to be trapping in the first place.
