How to create an AD User with a Powershell GUI? - powershell

Question

I am trying to create a GUI that can create new AD Users.
My Problem: When I press the Button "Speichern" it does not use the Data in the textboxs to create the AD User. Instead this text comes in the command console:
New ADUser cmdlet at command pipeline location 1
Specify values ​​for the following parameters:
Surname:
If I enter the Surname it will create the User with this Surname.
This is my Powershell script:
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
Import-Module ActiveDirectory
#GUI Oberfläche

$Form.Text = "Benutzer hinzufügen"

-AccountPassword (ConvertT0-SecureString "<redacted>" -AsPlainText -Force)
})
[void] $Form.ShowDialog()
Does someone have a solution for my problem?

Answer 1

I believe the problem is when you are assigning values.
taking this as an example:
#Textfeld Benutzeranmeldename
$TextboxBa= New-Object System.Windows.Forms.TextBox
$TextboxBa.Location = New-Object System.Drawing.Size(200,140)
$TextboxBa.Size = New-Object System.Drawing.Size(200,20)
$addBa = $TextboxBa.Text
$Form.Controls.Add($TextboxBa)
when you're assigning a value to $addBa the value of $TextboxBa.Text is most likely empty!
So you should probably change your $BTsave.Add_Click event to directly access the textbox value(s) rather than the empty variable.
Also worth noting is that PowerShell doesn't take kindly to line breaks. If you want to avoid long lines you have to add a back-tick character.
#Add User
$BTsave.Add_Click({
New-ADuser `
-Name $TextboxVa.Text `
-Path "Ou=Users, DC=domain, DC=com" `
-Givenname $Textboxvorname.Text `
-Surname $Textboxnachname.Text `
-SamAccountName $TextboxBa.Text `
-AccountPassword (ConvertTo-SecureString "<redacted>" -AsPlainText -Force)
})
