如何以编程方式将控件添加到VB.NET中的表单

Question

我正在Visual Basic 2010 Express Edition中处理清单。我不知道清单所需的字段数。我希望我可以在程序中使用for循环添加文本框/复选框/按钮。有没有一种方法可以在不使用工具箱的情况下向表单添加控件？我可以通过在程序中实例化控件来添加控件吗？

Answer 1

是。

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

    Dim MyTextbox as New Textbox

    With MyTextbox

       .Size = New Size(100,20)

       .Location = New Size(20,20)

    End With

    AddHandler MyTextbox.TextChanged, AddressOf MyTextbox_TextChanged

    Me.Controls.Add(MyTextbox)  

End Sub

Friend Sub MyTextbox_Changed(sender as Object, e as EventArgs)

   'Write code here.

End Sub
