Cant create 2nd textbox

I'm having problems with this code and I can't figure out why. It works fine the first time through but crashes with a "Parameter is not Valid" error the 2nd time through on this line:

Dim tbx As TextBox = New Windows.Forms.TextBox

The full code is as follows:

Dim tbx As TextBox = New Windows.Forms.TextBox
tbx.Name = tbxName
tbx.Size = New System.Drawing.Size(55, 12)
tbx.BorderStyle = BorderStyle.None
tbx.TextAlign = HorizontalAlignment.Center
Using f As Font = tbx.Font
  tbx.Font = New Font(f.FontFamily, 8, FontStyle.Bold)
End Using
tbx.Location = New System.Drawing.Point(xCords, 44)
Select Case tbx.Name
  Case "tbxBulk01" : tbx.Text = Bulk01Label
  Case "tbxBulk02" : tbx.Text = Bulk02Label
End Select
Me.Controls.Add(tbx)

Here's the stack trace:

at System.Drawing.Font.GetHeight(Graphics graphics) at System.Drawing.Font.GetHeight() at System.Drawing.Font.get_Height() at System.Windows.Forms.Control.get_FontHeight() at System.Windows.Forms.TextBoxBase.get_PreferredHeight() at System.Windows.Forms.TextBoxBase.get_DefaultSize() at System.Windows.Forms.Control..ctor(Boolean autoInstallSyncContext) at System.Windows.Forms.TextBoxBase..ctor() at System.Windows.Forms.TextBox..ctor()

Any help is appreciat开发者_JAVA技巧ed.

I know this is an old question but here is my answer.

I suspected the

USING .... END USING section as well.

I have just read that in the feedback too, oh well, never mind.

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim xCoords As Integer = 80
        Dim myTextBox As TextBox = New TextBox

        For index As Integer = 1 To 2
            myTextBox = New TextBox
            myTextBox.Name = "MyTextBox" & index.ToString
            myTextBox.Size = New System.Drawing.Size(55, 12)
            myTextBox.BorderStyle = BorderStyle.None
            myTextBox.TextAlign = HorizontalAlignment.Center
            myTextBox.Font = New System.Drawing.Font(myTextBox.Font.FontFamily, 8, FontStyle.Bold)
            myTextBox.Location = New System.Drawing.Point(index * xCoords, 44)
            Select Case index
                Case 1 : myTextBox.Text = "Bulk01Label"
                Case 2 : myTextBox.Text = "Bulk02Label"
            End Select
            Me.Controls.Add(myTextBox)
        Next

    End Sub
End Class
