Creating Controls in run-time

How can I create a control (any control, a textbox, a picture control, any OCX control,etc..) in runtime, from scrach?. I mean, it is possible to create a control via code?

you cannot create a control from scratch unless you already have at least one control (of the type you want to create) that is loaded on your form with index property set to any value.

if you don't want to see this initial control on you form, just set its visible property to false.  you create controls using the 'load' command then make its visible property to true.

Thanks, Janim, i've alredy assumed that a base control was necesary but i need more information.
OK, I understand the fact to have a contron of the type i want. Then the question is:
Let's suppose i have a command button for 1 action(in this case hidden, because i want this only as a "base"). How can i create copies of this button for x actions (assume that there is a variable ammount of actions, so i don't know how many buttons they may be)?
And, It's possible to do the same with other controls (Activex OCX, data controls, etc)?
Thanks.

there is a function calles 'LoadControl' in VB5, but you need an objects CLSID to use it. but look it up and try it

can you further explain your question?
by action do you mean the event corresponding to your control?
can you give me a sample algorithm of what you need to do?

Here is code to add / delete controls at runtime based on a control. This is a sample. I don't know your project :

Private Sub cmdAdd_Click ()
      If MaxId = 0 Then MaxId = 1      ' Set total option
                                                                  ' buttons.
      If MaxId > 8 Then Exit Sub      ' Only ten buttons
                                                                  ' allowed.
      MaxId = MaxId + 1                  ' Increment button count.
      Load optButton(MaxId)            ' Create new button.
      optButton(0).SetFocus            ' Reset button selection.
      ' Set new button under previous button.
      optButton(MaxId).Top = optButton(MaxId - 1)._
      Top + 400
      optButton(MaxId).Visible = True      ' Display new
                                                                  ' button.
      optButton(MaxId).Caption = "Option" & MaxId + 1
End Sub
      
Private Sub cmdDelete_Click ()
      If MaxId <= 1 Then Exit Sub      ' Keep first two
                                                                  ' buttons.
      Unload optButton(MaxId)            ' Delete last button.
      MaxId = MaxId - 1                        ' Decrement button count.
      optButton(0).SetFocus            ' Reset button selection.
End Sub
