Question

vb Picture1显示图片问题

在pictures\文件夹，有2张图片
打个比方
Picture1.Picture = LoadPicture(App.Path & "\pictures\MgI.jpg")
Picture1.Picture = LoadPicture(App.Path & "\pictures\MgI1.jpg")

想让这2张图片循环互换也就是，每1秒钟互换一次，代码应该怎么写 ，说白了就像放电影的道理一样
窗体有Picture1，有两个按键，一个时钟控键，按键1开始，按键2结束

Answer 1

timer1.in....=1000
sub timer1_time
if pic1.image=App.Path & "\pictures\MgI.jpg" then
pic1.image=LoadPicture(App.Path & "\pictures\MgI1.jpg")
else
pic1.image=LoadPicture(App.Path & "\pictures\MgI.jpg")
endif
end sub

sub command1_click
timer1.enable=true
end sub

sub command2_click
timer1.enable=false
end sub

Answer 2

Private Sub Timer1_Timer()
static i as integer
i=(i+1) mod 2
if i=0 then
Picture1.Picture = LoadPicture(App.Path & "\pictures\MgI.jpg")
else
Picture1.Picture = LoadPicture(App.Path & "\pictures\MgI1.jpg")
end if
End Sub
Private Sub Command1_Click()
timer1.enbled=true
timer1.interval=1000
End Sub
Private Sub Command2_Click()
timer1.enbled=false
End Sub
