I need to load a richtextbox during run time when a certain thing happens.

I use to do this with winsock on an array but I can't seem to do it the same way.   Any suggestions ?

So far i've got it loading a new one up setting it's position and making it visible but it's not working.

What have you used to do this ? Have you tried using controls collection to do that ? Here is a sample code.
Dim withevents ctlCommand as VB.COmmandButton

Set ctlCommand = Controls.Add("VB.CommandButton", _
                    "ctlCommand1", Form1)
ctlcommand.move 0,0
ctlcommand.caption = "YAHOO"

Thats how the control is born in runtime. I suppose if you loading an ActiveX control it must be stil referenced i would think. I think the control then must be redestributed when you making a setup.

I guess you are using a control array ?

I would normally have an instance of the control on a form, set its index to zero and make it invisible.

Then at run time do:

    Load myControl(NextControlIndex)
    With myControl(NextcontrolIndex)
        .Left = 100
        .Top = 100
        .Visible = True
    End With
    NextControlIndex = NextControlIndex+1

If thats what you're doing, in what way is it not working ?

Just tried the below code and it works... place a RTB on a form and a button. Then put the following code into the button and run. Everytime you press the button a new rich text box appears below and to the right of the last one :

Private Sub Command1_Click()

    Static nIndex As Integer
   
    nIndex = nIndex + 1
    Load RichTextBox1(nIndex)
    With RichTextBox1(nIndex)
        .Left = nIndex * .Width
        .Top = nIndex * .Height
        .Visible = True
    End With
   
End Sub

The problem with your code is guys that he doesn't want to create a control array in runtime he wants just a control in runtime wihtout having any control on the form at all where you just use load to create one. So the only way is to use VB Controls.ADD method to do so. Or there should be an API function similar to this.

VB6 supports .Add, Vb5 does not. If he's using VB5 then he must use an invisible "seed" control for the control array.

Thanks for the high interest..

I at first was going to load a richtextbox but I saw the array code and I think that will be easier since I'm not sure if i'll be needing more then one.

Thanks for all the info!
