    <p>So I've got a poweshell form in which you can add users to a listbox and at the same time to an arraylist. When I try to return the arraylist with all the users, it returns nothing.</p> <p>Here's my code</p> <pre><code>#---------------------# # Function AddUserGUI # #---------------------# Function AddUserGUI() { $AllUsers = New-Object System.Collections.ArrayList #---Form $Form = New-Object System.Windows.Forms.Form $Form.FormBorderStyle = "FixedSingle" $Form.Size = New-Object System.Drawing.Size(295,280) $Form.MaximizeBox = $False $Form.Text = "Add User(s)" $Form.StartPosition = "CenterScreen" $Form.Font = New-Object System.Drawing.Font("Segoe UI",9,0,3,1) #---TexBox $objTextBox = New-Object System.Windows.Forms.TextBox $objTextBox.Location = New-Object System.Drawing.Size(10,10) $objTextBox.Size = New-Object System.Drawing.Size(183,100) $objTextBox.MaxLength = 100 #---ListBox $objListBox = New-Object System.Windows.Forms.ListBox $objListBox.Location = New-Object System.Drawing.Size(10,45) $objListBox.Size = New-Object System.Drawing.Size(183,199) $objListBox.HorizontalScrollbar = $True #---Buttons $Add = New-Object System.Windows.Forms.Button $Add.Location = New-Object System.Drawing.Size(205,10) $Add.Size = New-Object System.Drawing.Size(75,23) $Add.FlatStyle = "PopUp" $Add.Text = "Add" $Remove = New-Object System.Windows.Forms.Button $Remove.Location = New-Object System.Drawing.Size(205,45) $Remove.Size = New-Object System.Drawing.Size(75,23) $Remove.FlatStyle = "PopUp" $Remove.Text = "Remove" $Confirm = New-Object System.Windows.Forms.Button $Confirm.Location = New-Object System.Drawing.Size(205,220) $Confirm.Size = New-Object System.Drawing.Size(75,23) $Confirm.FlatStyle = "PopUp" $Confirm.Text = "Confirm" #---Buttons On-Click Actions $Add_OnClick= { if($objTextBox.Text -ne "") { $UserChk = $true #[Bool](Get-ADObject -Filter { sAMAccountName -eq $objTextBox.Text } -Searchbase "ou=User_PFS,dc=pfs,dc=local") if($UserChk -eq $True) { if($objListBox.Items -contains $objTextBox.Text) {DisplayMsgBox "User already in list." "Duplicate entry" "Information" 0} ElseIf($objTextBox.Text -ne $NULL -and $objListBox.Items -notcontains $objTextBox.Text) { $objListBox.Items.Add($objTextBox.Text) [void]$AllUsers.Add($objTextBox.Text) } } ElseIf($UserChk -eq $False) {DisplayMsgBox "User not found." "Invalid User Name" "Information" 0} $objTextBox.Text = "" } } $Remove_OnClick= { $AllUsers.Remove($objListBox.SelectedItem) $objListBox.Items.Remove($objListBox.SelectedItem) } $Confirm_OnClick= { if($AllUsers.Count -eq 0) { DisplayMsgBox "Please add at least one user to the list." "No Users Found" "Information" 0 } ElseIf($AllUsers.Count -gt 0) { $Form.Close() Return $AllUsers } } #---Adding Elements to the form $Add.add_Click($Add_OnClick) $Remove.add_Click($Remove_OnClick) $Confirm.add_Click($Confirm_OnClick) $Form.Controls.Add($objListBox) $Form.Controls.Add($objTextBox) $Form.Controls.Add($Add) $Form.Controls.Add($Remove) $Form.Controls.Add($Confirm) #---Display Form $Form.ShowDialog()| Out-Null } $AllUsers = AddUserGUI foreach($User in $AllUsers){write-host $User} </code></pre> <p>The foreach loop generates no output whatsoever. How can I return this arraylist properly?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
