Hi,

Move the line of code.>>

Dim t As New TextBox to just after.>>

For count As Integer = 4 to 6

that way you generate a NEW textbox each time.

Give each a Location too. Try

t.Location = New Point(count * 75,50)

within the loop too.

If this is a Web based project you could also try.>>

Best of luck and Happy coding.

Hi,

I would do this with a button click though, not within a TextChanged event otherwise you will generate New TextBoxes every time the text is changed.

As this looks like a WINDOWS FORM based project you would need.>>

t.Name = "TextBox" & count.ToString

within the FOR NEXT next loop instead of

t.Id = "TextBox" & count.ToString

Remove the line

count = count + 1

as it interferes wih the FOR NEXT loop.

How many TextBoxes are you wanting in the end?

Best of luck and Happy coding.
