Delete cloned Controls

Getting Started
1

Good morning (o;

For an application that creates an individual user interface based on what a serial device returns I use Control templates to add buttons, labels and textfields…

Dim newField as DesktopTextField = new templateField
newField.Tooltip = "Wert zwischen " + tokens(2) + " und " + tokens(3)
newField.visible = true
newField.Text = tokens(1)
TextFields.Add(newField)

All fine so far…

But how would I go along to remove those Controls when not needed anymore?

thanks in advance

Ah looks like method Close seems to be the right thing…

Closes a control.

Closing a control permanently removes the control from memory, making it impossible to access. You can close both non-indexed controls and indexed controls. When you close an indexed control, the indexes for the remaining controls will shift downward so that the indexes start with zero and are consecutive.

Instead of DIMming, use a property for reference.

For instance, add newField() as DesktopTextField to the window.

Your code would then become:

newField.add(new templateField)
newField.Tooltip = "Wert zwischen " + tokens(2) + " und " + tokens(3)
newField.visible = true
newField.Text = tokens(1)
TextFields.Add(newField)

You can then do

newField(0).close

Using an array, you can add many controls. But you got to figure which index to use. Instead of an array, you can use a series of properties. But it is less elegant.

He might already be doing that with this code…

TextFields.Add(newField)

Well I hope it is doing that…at least it works pefectly after connecting and querying the device…and removing with a For Each when closing the serial connection :wink:

BTW: Can SerialConnection also be cloned like that?

Oops, you are right.
