新建窗体,把maximizebox属性和MinimizeBox 属性设为false,再添加一个Label1放置文字一个Picturebox1放图片。
在窗体的load事件中:
Private Sub Form1_Load() Handles Me.Load
Text="我的VB.NET程序"
PuctureBox1.Image=Image.FromFile(图片路径如e:\pic.jpg)
End Sub
窗体Click事件:
Private Sub Form1_Click() Handles Me.Click
Text="单击窗体"
Label1.Text="欢迎使用VB.NET"
End Sub
窗体DoubleClick事件
Private Sub Form1_DoubleClick() Handles Me.DoubleClick
Text="双击窗体"
Label1.Text = "谢谢使用!"
End Sub
