用VB.NET创建一个三层应用程序的例子……

CType(Me.DataGrid1, System.ComponentModel.ISupportInitialize).BeginInit()

Me.SuspendLayout()

@#

@#Button1

@#

Me.Button1.Location = New System.Drawing.Point(88, 360)

Me.Button1.Name = "Button1"

Me.Button1.TabIndex = 0

Me.Button1.Text = "load"

@#

@#Button2

@#

Me.Button2.Location = New System.Drawing.Point(232, 360)

Me.Button2.Name = "Button2"

Me.Button2.TabIndex = 1

Me.Button2.Text = "update"

@#

@#Button3

@#

Me.Button3.Location = New System.Drawing.Point(376, 360)

Me.Button3.Name = "Button3"

Me.Button3.TabIndex = 2

Me.Button3.Text = "clear"

@#

@#Client_DataSet

@#

Me.Client_DataSet.DataSetName = "Client_DataSet"
