VB.Net图解入门(图片较多,请稍等片刻)

Imports System.ComponentModel

Imports System.Drawing

Imports System.WinForms

Imports 的作用与with ……… .end with的意思是一样的 system.drawing.xxyy 在使用了Imports System.Drawing以后都可以写成xxyy。

Public Class Form1 在Class与End Class中间就是一个类了。

Inherits System.WinForms.Form

Inherits表示这个类由System.WinForms.Form派生出来,具有所有父类已有的方法成员

Public Sub New () 等于VB6K中的dim form as object 加 form=new xxxform,加 load form

MyBase .New

Form1 = Me

InitializeComponent 等于VB6中的Form_Load事件

Overrides Public Sub Dispose()等于VB6的form_unload事件 form1.dispose等于VB6的unload form1

MyBase .Dispose

components.Dispose

End Sub

Region " Windows Form Designer generated code "

Region是形成窗体的代码,不要直接修改,丛属性窗口设置他们

Private components As System.ComponentModel.Container

Private WithEvents Button1 As System.WinForms.Button

这一句改成 Public WithEvents Button1 As System.WinForms.Button以后你就可以在别的类中调用他,你应该在属性窗口修改他

Dim WithEvents Form1 As System.WinForms.Form

Private Sub InitializeComponent()

Me .components = New System.ComponentModel.Container()

Me .Button1 = New System.WinForms.Button()

Button1.Location = New System.Drawing.Point(200, 88)

Button1.Size = New System.Drawing.Size(56, 32)

Button1.TabIndex = 0

Button1.Text = "Button1"

Me .Text = "Form1"

Me .AutoScaleBaseSize = New System.Drawing.Size(6, 14)

Me .Controls.Add(Button1)

End Sub

End Region

Protected Sub Button1_Click( ByVal sender As Object , ByVal e As System.EventArgs)

End Sub

End Class

build 成 exe 就行了,

只要对方装了 Microsoft .NET Framework SDK ,就不需要安装程序了,所有 DLL 等组件只要拷到当前目录即可,不存在注册的问题。 Net 的完全安装包大得惊人。好在支持大部分的系统( win9x,win2000 )
