Internet Explorer object doesn't have Document child


I'm trying to get my hands on filling in a form with PowerShell. So I am simply trying to do this:

$ieObject = New-Object -ComObject 'InternetExplorer.Application';
$ieObject.Visible = $true;;
$currentDocument = $ieObject.Document;
$inputbox = $currentDocument.getElementByID('randSets');
$inputbox.value = "My Value"; 

However this gives me the error

You cannot call a method on a null-valued expression.
At line:5 char:1
+ $inputbox = $currentDocument.getElementByID("randSets");

I don't exactly know why but my ieObject doesn't have all the properties (I only have 9 when I'm supposed to have around 50)and methods it should have. When I use Get-Member I can't see Document in there so is it normal or am I doing something really wrong?

PS C:\Users\n> $ieObject | Get-Member

   TypeName: System.__ComObject

Name                      MemberType Definition

ToString                  Method     string ToString()                                     

Thank you in advance!

I am using:

  • Windows 10 Enterprise (so I'm thinking maybe my company blocked some features, I will check with my IT department)
  • Powershell version is 5.1
  • Internet explorer version 11.885

EDIT: as suggested in the comment I tried to use VBA to do the same thing as my powershell script and I got the same error on the Document object Method 'Document' of object 'IWebBrowser2' failed'. This means I can't access properly my Internet Explorer application. In this case I think I should wait for the final answer of my IT department and then add more to this.

So I have access to the object and every property of it until I use Navigate. Then I get errors even for Get-Member like:

Get-Member : The following exception occurred while retrieving the string representation 
for property "Application" : "The RPC server is unavailable. (Exception from HRESULT:

What looks like is happening is the page has not loaded by the time you are calling $currentDocument = $ieObject.Document; causing $currentDocument to be $null.

You should be able to fix it by using .Busy

$ieObject = New-Object -ComObject 'InternetExplorer.Application'
$ieObject.Visible = $true
   Start-Sleep -Milliseconds 10
$currentDocument = $ieObject.Document
$inputbox = $currentDocument.getElementByID('randSets')

This is working here:

$ieObject = New-Object -Com InternetExplorer.Application

$ieObject.Visible = $true

while ($ieObject.busy) {
        sleep -seconds 1

$currentDocument = $ieObject.Document
$inputbox = $currentDocument.getElementByID('randSets')
$inputbox.value = "My Value"

You have to wait till the browser has loaded all objects.

So the issue was actually very simple, so simple I didn't think about it... I have to run the programs as administrator and then it works.

Thank you all for your help!
