Question

I’m stuck with VB6 and I’m using Form.Controls.Add(...) to create a bunch of controls at runtime.

Unfortunately this seems to be a very slow process, with heavy flickering.

Is there any way to speed up the process? Perhaps it’s possible to somehow notify VB6 that I’m doing a mass-insert of new controls.

You can use a hidden picturebox for the container like this

Set oCtl = Controls.Add("VB.TextBox", "txtMy1", picHidden)

Then you can either show the container which will be as fast as can be or hide the controls and reset container like this

oCtl.Visible = False
Set oCtl.Container = Form1 ' or picHidden.Container

In any case you can reduce flicker by using a hidden container.
