    Question

    I am using a collection in order to track controls added
    during runtime. How do I delete these controls when I am finished with them?

    Code:
    unload coll(Index)
    coll.Remove Index

    writing software in C++ is like driving rivets into steel beam with a toothpick.
    writing haskell makes your life easier:
    reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13

    Deleting controls is the same as "deleting" (called closing in programming terminology) an App.

    Add the following to a Form with 2 CommandButtons called Command1 and Command2. When you press Command2, it will close (delete) Command1.
    Code:
    Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
    Private Declare Function DestroyWindow Lib "user32" (ByVal hwnd As Long) As Long
    Private Const WM_CLOSE = &H10
    
    Private Sub Command2_Click()
        SendMessage Command1.hwnd, WM_CLOSE, 0, 0
        DestroyWindow Command1.hwnd
    End Sub
