error :

Get-ADOrganizationalUnit : the syntax of the object name is incorrect

Combobox2_ville (Get-ADOrganizationalUnit <<<< -SearchBase "OU=$OU, DC=CONTOSO,DC=FR" - Searchscope 1 -filter * ) -DisplayMember "Name"

I can not seem to have the value of the second combobox

If I put the value manually it works

Can you help me ?

Thank you :)

$ous=Get-ADOrganizationalUnit -Searchscope 1 -Filter *
Load-ComboBox $Combobox1_BU $ous  -DisplayMember Name

You must load the comboboxes in the Load event of the form or in an event.  LOading outside oof an event will produce unreliable results.

Here is a better way to load a combobox.  I have fixed many errors in your code but not all. It is also not possible to figure out what youa re doing as you have just sprinkled odd bits of code into code that was generated by a tool.

This works as far as loading comboboxes:

It doesn't work

I don't have the value of the first combobox

Thanks :)

I have no idea what you are talking about.  Your issue was that you couldn't get the comobo boxes to load.  Now you are asking a completely different question.

Change this line: $form1.ShowDialog()| Out-Null

to the following:

$form1.ShowDialog()
$form1

Then call the form like this:

$form=GenerateForm

Now you have all of the values:

$form.Controls['comboBox1_BU'].SelectedItem.Name

Example AD

A

-A1

-A2

B

-B1

...

When i selected A in the first combobox

I want it puts me in the UO A

In the second combobox there will be A1 - A2

You understand ?

I'm french, sorry for my english ^^

That has nothing to do with your original question.

When the combobox changes value that event is used to load the data into other controls. We use the "SelectionChanged" Event.

Here is how to event the combobox.

$comboBox1_BU.add_SelectedIndexChanged({ ... code .. })

In that event load the second box.

Sorry. You keep changing the question and what yo are doing. I suggest you start by learning PowerShell before trying to understand how to use PowerShell with forms.

If you don't understand the posts and why your code is badly broken then  I cannot help you.

My last offer. Here is a complete and working demo of how to use ComboBoxes.
