VB.NT用的是触发事件,一按就会触发,要不你加个timer控件,延迟一秒
标题的问题:你先把图片保存,再加载
vb.net 怎么来回切换图片?1、添加控件Picturebox1和控件Timer1,将Timer1的Interval属性改为1000(即1秒),Enabled属性改为True
2、假设你要循环切换4张图片,你可以添加如下代码即可实现:
Dim a As Integer = 0
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If a = 4 Then
a = 0
Else
a = a + 1
End If
If a = 0 Then Me.PictureBox1.Image = Image.FromFile("1.jpg")
If a = 1 Then Me.PictureBox1.Image = Image.FromFile("2.jpg")
If a = 2 Then Me.PictureBox1.Image = Image.FromFile("3.jpg")
If a = 3 Then Me.PictureBox1.Image = Image.FromFile("4.jpg")
End Sub
