Question

I’m a beginner in WinForms VB NET programming. I need to create text box at a run time.

I found example in a search engine how to implement this:

Private Sub Command1_Click()
    Dim TextControl As TextBox
    ControlID = ControlID + 1
    Load Text1(ControlID)
    Set TextControl = Text1(ControlID)
    With TextControl
        .Left = (Text1(ControlID - 1).Left + Text1(ControlID - 1).Width) + 10
        .Top = 20
        .Width = 100
        .Height = 20
        .Visible = True
    End With
End Sub

But I have some difficulties with example’s code.

Would someone explain the following VB NET code rows?

    Load Text1(ControlID)
    Set TextControl = Text1(ControlID)
    With TextControl
    End With

You can check the following example that does exactly what you want to:

Private Sub btnCreateTextbox_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCreateTextbox.Click
    Dim textbox1 As New TextBox
    textbox1.Name = "Textbox1"
    textbox1.Size = New Size(170, 20)
    textbox1.Location = New Point(167, 32)
    GroupBox1.Controls.Add(textbox1)
End Sub
