将文本添加到自动标签和文本框vb.net

Question

以下代码创建/格式化标签和文本框到一个groupbox。

我的问题是，我想改变文本框文本到1和0定期（如夹层），我不知道如何。

Private Sub ResizeData() 
    ' Create as many textboxes as fit into window 
    grpData.Controls.Clear() 
    Dim x As Integer = 0 
    Dim y As Integer = 10 
    Dim z As Integer = 20 
    While y < grpData.Size.Width - 100 
     labData = New Label() 
     grpData.Controls.Add(labData) 
     labData.Size = New System.Drawing.Size(30, 20) 
     labData.Location = New System.Drawing.Point(y, z) 


     labData.Text = Convert.ToString(x + 1) 

     txtData = New TextBox() 
     grpData.Controls.Add(txtData) 
     txtData.Size = New System.Drawing.Size(50, 20) 
     txtData.Location = New System.Drawing.Point(y + 30, z) 
     txtData.TextAlign = System.Windows.Forms.HorizontalAlignment.Right 
     txtData.Tag = x 


     x += 1 
     z = z + txtData.Size.Height + 5 
     If z > grpData.Size.Height - 40 Then 
      y = y + 100 
      z = 20 
     End If 
    End While 

End Sub 

我需要的东西是这样的：

txtData1.text="1" 
txtData2.text="0" 
txtData3.text="1" 
txtData4.text="0" 

...等等。

谢谢！

Private Sub ResizeData() 
    ' Create as many textboxes as fit into window 
    grpData.Controls.Clear() 
    Dim a As Integer = 1 
    Dim x As Integer = 1 
    Dim y As Integer = 10 
    Dim z As Integer = 20 
    While y < grpData.Size.Width - 100 

     Dim labData As New Label() 
     grpData.Controls.Add(labData) 
     labData.Size = New System.Drawing.Size(30, 20) 
     labData.Location = New System.Drawing.Point(y, z) 


     labData.Text = Convert.ToString(a) 


     Dim txtData As New TextBox() 
     grpData.Controls.Add(txtData) 
     txtData.Size = New System.Drawing.Size(50, 20) 
     txtData.Location = New System.Drawing.Point(y + 30, z) 
     txtData.TextAlign = System.Windows.Forms.HorizontalAlignment.Right 
     txtData.Tag = x 
     txtData.Text = x 

     a += 1 
     If x = 1 Then 
      x = 0 
     ElseIf x = 0 Then 
      x = 1 
     End If 

     z = z + txtData.Size.Height + 5 
     If z > grpData.Size.Height - 40 Then 
      y = y + 100 
      z = 20 
     End If 
    End While 

End Sub 

为了让只有第2文本框值为'1'，使用上述相同的代码修改这3行：

Dim txtData As New TextBox() With {.Name = "txt" & a} 
txtData.Text = 0 
If txtData.Name = "txt1" Or txtData.Name = "txt2" Then txtData.Text = 1 'add this line just below the above one

也许使用布尔值将工作。没有清洁的方式，但它应该工作

当你暗淡的一切：

Dim even as boolean 

而且txtData的所有属性更改后：

if even then 
    txtData.Text=1 
else 
    txtData.Text=0 
end if 
even= not even
