----制作“Hello.NET”程序
作者:高山
用下面很简单的方法,就可以制作一个“Hello.NET”小程序,同时可以掌握一些控件的用法。
Public Class Form1
Inherits System.Windows.Forms.Form
#Region " Windows 窗体设计器生成的代码 "
Public Sub New()
MyBase.New()
'该调用是 Windows 窗体设计器所必需的。
InitializeComponent()
'在 InitializeComponent() 调用之后添加任何初始化
End Sub
'窗体重写处置以清理组件列表。
Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
If disposing Then
If Not (components Is Nothing) Then
components.Dispose()
End If
End If
MyBase.Dispose(disposing)
End Sub
'Windows 窗体设计器所必需的
Private components As System.ComponentModel.IContainer
'注意:以下过程是 Windows 窗体设计器所必需的
'可以使用 Windows 窗体设计器修改此过程。
'不要使用代码编辑器修改它。
Friend WithEvents Button1 As System.Windows.Forms.Button
Friend WithEvents TextBox1 As System.Windows.Forms.TextBox
<System.Diagnostics.DebuggerStepThrough()>Private Sub InitializeComponent()
Me.Button1 = New System.Windows.Forms.Button()
Me.TextBox1 = New System.Windows.Forms.TextBox()
Me.SuspendLayout()
'
'Button1
'
Me.Button1.Location = New System.Drawing.Point(16, 112)
Me.Button1.Name = "Button1"
Me.Button1.TabIndex = 0
Me.Button1.Text = "OK"
'
'TextBox1
'
Me.TextBox1.Location = New System.Drawing.Point(160, 112)
Me.TextBox1.Name = "TextBox1"
Me.TextBox1.TabIndex = 1
Me.TextBox1.Text = ""
'
'Form1
'
Me.AutoScaleBaseSize = New System.Drawing.Size(6, 14)
Me.ClientSize = New System.Drawing.Size(292, 266)
Me.Controls.AddRange(New System.Windows.Forms.Control() {Me.TextBox1, Me.Button1})
Me.Name = "Form1"
Me.Text = "Hello,VB.NET"
Me.ResumeLayout(False)
End Sub
#End Region
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
TextBox1.Text = "Hello,VB.NET!"
End Sub
End Class
按功能键盘上的F5 运行就可以! 如果有错误,VB会出现新窗口,用汉字写出如何错误。在新窗口内点击调试,在代码窗口中出错的代码为黄色背景。 最后保存程序,单击“文件”菜单——选择“保存工程”。需要保存两个窗体,首先是.frm的应用程序窗体,然后是.vbp的工程文件。Private Sub Command1_Click()Me.Cls
Dim N As Integer, i As Integer
N = InputBox("n=", , 9)
For i = 1 To 2 * N - 1
If i <= N Then
Print Space(N - i) + String(2 * i - 1, CStr(i))
Else
Print Space(N - (2 * N - i)) + String(2 * (2 * N - i) - 1, CStr(2 * N - i))
End If
Next i
End Sub
