Autoit randomly select photo from selection (IE)

[peterchua89]

Hi Autoit Experts,

I have a question regarding random selection of photos from IE. I've been searching from forum & Google with no luck. The only thread I found is >Link & >Link, but both of this thread does not explain more in detail. Maybe any experts can help me out here?

Objective: To select (10) random photos from a selection in IE.

<div id="selectable_photos">
      <div class="form_line">
        <div class="heading">Shared Photos</div>
        <div class="comment">Click on photo to select / unselect from shared library.</div>

Q: Can Autoit randomly select 10 out of those random Image links? How can we get into the links?

I have tried using _IEImgClick() and it work but only able to select the photo by its specific link, what if I dont know what is after "http://dsc.propwall.com/photos/" or I dont know what is the links? Is it still be possible?

Yes it can. First you have to count how many images there and identify what kind they can be (jpg, gif, etc). Then put the images in a list. I would use an array. Then use autoits random function to choose randomly 10 images from the array. 1 question - Are you looking for autoit to choose 10 thumbnails or the images that the thumbnails link to?

And your link doesnt work for me.

Hi @computergroove, yeah Im looking for autoit to randomly choose 10 thumbnails from the above HTML. The links "http://dsc.propwall.com/photos/....." is actually extracted from the html. it seems to me that those image links/thumbnails that I want to select are usually start with ""http://dsc.propwall.com/photos/ "......." and so on. How can we make autoit to only look for image links that start with "http://dsc.propwall.com/photos/"?

Also the file type are usually JPG. (can autoit select links that ends with a JPG extention?)

Any clue to give me?

I can help you write some code but I need a working website to test it on. Can you provide the web address or another one like it?

Edit - I made this for a guy on the forums that taked am html file and gets all the specific links from it and puts it into an array:

#include <array.au3>
#include <File.au3>
#include <String.au3>

Global $temp
Global $aArray[0]
$temp = FileRead(@ScriptDir & '\Syncron Solutions - User.htm');get your url and put it here
$aArray = _StringBetween($temp,'<li class="duallist-item"','">',1);Change the info in the () to the common start and end of the string
_ArrayDisplay($aArray)

Try this.

#include <IE.au3>
#include <Array.au3>

Local $iNumOfRandImgsRet = 8

;Get All Image links into an array.
; Either
Local $oIE = _IECreate("http://www.autoitscript.com/", 0, 1) ; <--- Last "1" parameter shows browser window.
; Or
#cs
    Local $oIE = _IECreate("about:blank", 0, 0) ; <--- Last "0" parameter hides browser window.
    _IEDocWriteHTML($oIE, FileRead("HtmTextFromPost1.htm")) ; Text from Post#1 saved to "HtmTextFromPost1.htm" file in same folder as this script, or, use full path name.
    _IEAction($oIE, "refresh")
#ce

Local $oImgs = _IEImgGetCollection($oIE)
Local $iNumImg = @extended
Local $aImgArray[$iNumImg] ; Array to hold all image links
Local $iCount = -1
For $oImg In $oImgs
    $iCount += 1
    $aImgArray[$iCount] = $oImg.src
Next
_IEQuit($oIE)

; Get a unique array of a number of random links.
_ArrayUnique($aImgArray) ; Ensure there are no duplicate image links.
_ArrayDisplay($aImgArray, "All " & $iNumImg & " Images Found")
_ArrayShuffle($aImgArray) ; Randomize array
_ArrayDelete($aImgArray, Execute('"' & $iNumOfRandImgsRet & '-' & (UBound($aImgArray) - 1) & '"'))
_ArrayDisplay($aImgArray, $iNumOfRandImgsRet & " Random Images")

@Malkey, that script works great!!    However if I may ask again because I really dont understand how arrays work. The links displayed out, can I put a conditional filter whereby the 8 Randoms links displayed must contains "http://dsc.propwall.com/photos/....."? if yes which array function I should be using?

Sorry Im kind of new here.. really did my best trying to understand array here..

This loop is adding things to your array, i would put your condition here.   

For $oImg In $oImgs  

  $iCount += 1  

If this item meets this condition then $aImgArray[$iCount] = $oImg.src

Next

 

And checking to see if a substring exists in a string, is a string function.

Arrays are storage bins.  Sort of like an egg carton.

If I bought a dozen eggs, there would be 12 slots to hold my eggs.

In autoit, our slots are designed with brackets, and the number of slots.

[12] as an example

so...

$a_array[12] holds 12 slots I can access data from, starting with index 0 and ending with 11

eg.

$a_array[0] = "egg 1"

$a_array[1] = "egg 2"

etc...

$a_array[11] = "egg 12"

This may help you much better, but I understood it myself when I thought of the egg container.
