How can I get rid of extra characters in TextBox? - powershell

Question

The intent of this form is to retreive first a username then use that username to retreive an email address. it does get the address but it also retreives other characters as well. textbox3 ends up reading #{EmailAddress=first.last#domain.com}. I have tried trimming characters but that did not work.

Answer 1

There are two issues with your code:
As explained in a comment, you need to get the value from the EmailAddress property of your object, otherwise, because the .Text property value can only be a string, what you will see as a result is a string representation of a PSCustomObject.
The assignment of $User.Text is invalid and will produce an error unless you're not showing us your actual code. The $User variable not defined hence cannot have a .Text property. Trying to assign anything to it will produce an error such as:
The property 'Text' cannot be found on this object. Verify that the property exists and can be set.
How should your function to solve both issues:
function getacctname {
$fname, $lname = $TextBox1.Text.Trim(), $TextBox2.Text.Trim()
$TextBox3.Text = Get-ADUser -Filter "GivenName -eq '$fname' -and SurName -eq '$lname'" -Properties mail |
Select-Object SamAccountName, mail |
Out-Gridview -Title 'Windows Logon' -PassThru |
Select-Object -ExpandProperty mail
}
As aside, I would recommend you to make $TextBox3 a ReadOnly TextBox:
$TextBox3.ReadOnly = $true
