Get-UiaEdit failed to get control


Note that here UIA is used instead of ComObject "internetExplorer.Application"

because windows popups started by some webs are to be managed

Import-Module UIAutomation

starting I.E 8 on Win2003

$prc = Start-Process 'C:\Program Files\Internet Explorer\iexplore.exe' -PassThru

BUG : $prc.ID is wrong when another I.E window is already open

sleep -Seconds 2;

$wnd = Get-UiaWindow -pid $prc.Id

test.htm contains :



<table class="UsernamePasswordTable">

<tr><td>DAS ID: </td><td><input name="tb1" type="text" id="id1" /></td></tr>

<tr><td>Password: </td><td><input name="tb2" type="text" id="id2" /></td></tr>




$wnd | Get-UIAEdit -name 'Address' | Set-UIAEditText 'test.htm'

$wnd | Get-UIAButton -name "test" | Invoke-UIAButtonClick

$td = $wnd | Get-UIAText -name 'DAS ID: '

$tr = $td | Get-UIAControlParent

$table = $tr | Get-UIAControlParent

put OK from <TABLE> object but into both fields

$table | Get-UIAEdit | Set-UIAEditText 'set from table'

text field is accessible from the TR object

($tr | Get-UIAtext).Current.Name

but Edit field is not accessible from <TR> object

$tr | Get-UIAEdit | Set-UIAEditText 'set from tr'

BUG => Get-UiaEdit : failed to get control in 5000 milliseconds by: title: '', automationId: '', className: '', value: ''.

first of all about the Start-Process cmdlet. Some applications run something like 'engine' that in turn runs the app itself. For example, mmc.exe 32-bit on 64-bit Windows. I suspect that IE works similarly: it has a starter executable and the browser tab window.
Anyway, please don't address problem with the Start-Process cmdlet to me - thi is Microsoft's I can't fix it. :)

Now about the code - I'm on Windows 8 64-bit now with IE10 and I hope that latest IEs work more or less in a similar fashion. This code works for me (attached), UIAutomation 0.8.7 Beta 2:
# your test file c:\1\test.htm

[int]$id = 123
[string]$password = "pwd"

# browsers usually accept path to an html file as input
Start-Process iexplore -ArgumentList "C:\1\test.htm" -PassThru
# just got the sleep from your code
sleep -Seconds 2
# to be sure that the window contains necessary controls, there is the -WithControl parameter
# however, always work with as less windows as possible
$wnd = Get-UiaWindow -ProcessName iexplore -WithControl @{contorlType="edit";class="edit"},@{controlType="text";name="das*"},@{controlType="text";name="pass*"}

# you don't need the table
# $table = $wnd | Get-UIAText -name DAS* | Get-UIAControlParent | Get-UIAControlParent

# instead, go up to the custom objects that are parents of the text boxes and get their siblings respectively:
Get-UIAText -name DAS* | Get-UIAControlParent | Get-UIAControlNextSibling | Get-UiaEdit | Set-UiaEditText $id
Get-UIAText -name pass* | Get-UIAControlParent | Get-UIAControlNextSibling | Get-UiaEdit | Set-UiaEditText $password
My IE 10 runs 2 process on the first start and adds one more process on every next time I run the Start-Process cmdlet.

Regarding the buf with Get-UiaEdit. I don't know what set of controls is seen in IE 8, in IE 10 I have for every pair of controls (text + edit) the following:

table - another custom - edit
This explains how the edit is accessible from the table and inaccessible from the custom that is over the text.

Hi, Many thanks for the quick workaround, which is also working on IE8
