_IEEmbedded2! UDF

7 posts in this topic

#1 ·  Posted (edited)

Yet another IE UDF, but this time I "covered all angels" to make it as close to "embedded" as possible, the biggest inspiration came from Dale

Anyway, one of the issues with the other "snipplets\UDF's" is that $WS_POPUP style will cause other Windows to overlap, even though you clicked on the GUI's "Embedded window". see picture:

This issue is solved, but there is an option to disable it, if the user want

One more small issue with others IE Embedded UDF's is that implementation should not be so much different than the original implementation was. I am not ranting, I am just speaking for my mind.

So here we go:

This is how the classic _IeCreateEmbedded() implementation goes down

#include <IE.au3>

Local $hGUI = GUICreate("_IECreateEmbedded", 800, 600)

Local $oIE = _IECreateEmbedded()
GUICtrlCreateObj($oIE, 0, 0, 800, 600)

GUISetState()

_IENavigate($oIE, "https://www.google.se")

While GUIGetMsg() <> - 3
wend

and this is how _IeCreateEmbedded2() is implemented

#include <IE.au3>
#include <_IECreateEmbedded2.au3>

Local $hGUI = GUICreate("_IECreateEmbedded", 800, 600)

Local $oIE = _IEEmbedded2_Create($hGUI, 0, 0, 800, 600)

GUISetState()

_IENavigate($oIE, "https://www.google.se")

While GUIGetMsg() <> - 3
wend

The only downside with this implementation is that _IECreateEmbedded2() is not an GUI control, it only has our Com Object, so I added basic manipulation.

I will change \ add more options based on user requests or if I feel like it.

_IEEmbedded2_Move($iLeft, $iTop, $iWidth = Default, $iHeight = Default) ;Similar to AutoIT's WinMove
_IEEmbedded2_Hide()
_IEEmbedded2_Show()


Here is a GUI example with different options, so you can test some of the functionality

 Example.au3

#include <_IEEmbedded2.au3>

Local $hGUI = GUICreate("_IEEmbedded2 Example Gui", 1575, 600)
Local $iDMove = GUICtrlCreateButton("Move", 0, 0, 225, 50)
Local $iDHide = GUICtrlCreateButton("Hide", 225, 0, 225, 50)
Local $iDShow = GUICtrlCreateButton("Show", 450, 0, 225, 50)
Local $iDnav = GUICtrlCreateButton("Navigate", 675, 0, 225, 50)
Local $iDestroy = GUICtrlCreateButton("Destroy", 900, 0, 225, 50)
Local $iDCreate = GUICtrlCreateButton('Create with ($iCmdLine = "-extoff -private")', 1125, 0, 225, 50)
Local $iDCreateNoWsChildOnBlur = GUICtrlCreateButton("Create with ($iWsChildOnBlurMS = 0)", 1350, 0, 225, 50)

Local $oIE = _IEEmbedded2_Create($hGUI, 0, 50, 1575, 550, "http://www.google.se/", Default, Default, Default)

If you are looking to improve this for general use, you might replace the following line, to get the path ti IE from the registry.

Local $sIexplorePath = @ProgramFilesDir & "\Internet Explorer\Iexplore.exe"

You are correct, but before I change my code, I want to know if its possible for non admin users to still obtain this value

RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\IEXPLORE.EXE", "")

Hello Tarre,

Excellent job! I am grateful that I don't have to change much of my code to implement your new UDF!

However, in your example, when it starts or if I launch a newly created 'embedded' window, the first thing I see is a big white screen covering my entire display. It appears to shrink down into the parent window and display the correct page, but is there a way to prevent the initial Full-Screen 'embedded' browser window?

Thank you!

The initial Full-Screen 'embedded' browser window is by design, or am I just missing something? Anyone else?

Hello @coffeeturtle, the big window you see is the iexplore in kioskmode. The udf tries to minimize it as soon as possible to hide it on ie11>. Is it stuck for a long time? Or does it disappear after a while?

I will see if its possible to make it silent on creation

I have updated the UDF to hide the iexplore window as soon as it shows up.

      Hi, I'm trying to find a text value inside of a html.
      This is what the line looks like normally:
      <p id="line1" class> <span class="bot">TEXT HERE</span> </p> The text then changes to a non breaking space:
      <p id="line1" class> <span class="bot">&nbsp;</span> </p> And then it changes back to normal text but it's different every time.
      Can I code this so that it grabs the text every time it changes and has a variable that represents it?
      I currently have this inside of my loop:
      $span = .document.getElementsByTagName("span") For $text In $span If $text.value = "&nbsp;" Then Sleep(50) MsgBox(0,0,0) ;messagebox to test if it can be found, but I don't know how to grab the text EndIf Next The problem is that there are many other lines in the html that have the same span but are called "line3", "line5", etc and the one I need is from "line1".
      I will appreciate if anyone can help with this!

      I have kept below line to wait for IE to load the site completely and continue.
      _IELoadWait($oIE)
       
      But, the code is continuing without waiting for it and I my execution is failing as the elements are not loaded completely.

       
      Any suggestions for alternate code to wait for the browser to load completely?

      We can select elements in IE using their IDs as below.
      Local $oDiv = _IEGetObjById($oIE, "x-auto-16-input") But to one button in the webpage, there is no ID to it.
      In selenium we have option to select this element using the CssSelector and clicked the button using below code in c# selenium.
      driver.FindElement(By.CssSelector("button.x-btn-text")).Click(); What is the alternative for this in AUtoIT?

      Good morning everyone
      I worked a bit on a little project of mine, and I managed to do what I was trying to do, or, automate a quiz in AutoIt.
      Now, everything works fine but, in order to achieve what I'm trying to achive, I'd like to make this script run faster.
      I'll attach a portion of the code in order to let you understand what my script does.
      $objIE_h1 = _IETagNameGetCollection($objIE, "h1") ; Take the text of the answer If @error Then ConsoleWrite("Errore durante la lettura degli h1 nella pagina. - Errore: " & @error & @CRLF) Else For $objElement In $objIE_h1 $strInnerText = $objElement.innerText Next Select Case StringInStr($strInnerText, "QUESTION") ; Here is the question ; PS4 PRO $objSpans = _IETagNameGetCollection($objIE, "span") ; Answers are stored here For $objElement In $objSpans If $i >= 4 Then $strAnswer = $objElement.innerText ; Take the text of the answer n° 0, 1, 2, 3 If StringInStr($strAnswer, "CORRECT ANSWER") Then ; If I match the correct answer, then, I have to click on the input with answer id = answer_i $j = $i - 4 $objInput = _IEGetObjById($objIE, "answer_" & $j) If @error Then ConsoleWrite("Errore durante la lettura della risposta #" & $i & " - Errore: " & @error & @CRLF) Else _IEAction($objInput, "click") If @error Then ConsoleWrite("Errore durante il click sull'elemento. - Errore: " & @error) Else ConsoleWrite($j & ") Risposta: " & $strAnswer & @CRLF) ExitLoop EndIf EndIf EndIf $i+=1 Else $i+=1 EndIf Next $i = 0 $j = 0 This is what my script does.
      Questions are 20, in which I have 15 multiple choice question, 2 images ( on which I use _IEImgClick() ), and 3 text inputs ( a simple send with the text I have to enter ).
      How can I make all of these, faster?
      If I reach this goal, I've probably done one of my best goals in life, and I'd like to share my happiness with you, giving a huge donation to this fantastic community!
      Thanks for your help
