2樓：匿名使用者
你什麼時候要？怎麼發給你？
(vb) 請問這道題怎麼做的？ 求步驟 謝謝 50
3樓：匿名使用者
f函式中的 x引數是傳址 改變x值就會改變帶入時的變數的值y=f函式返回的值 =x*y=20*2=40x在f函式中被修改了值 所以x=20
答案c已經結貼無法回答 就在此回答你上一題的疑問列表選項序號從0開始 所以序號1 即第二個選項內容
請問這道vb題怎麼做？？
4樓：vb程式設計解放雙手
準備3張**，分別是紅燈亮，黃燈亮和綠燈亮時的**！，在視窗中拖入乙個timer控制項,乙個**控制項，2個按鈕，乙個標籤！
在timer事件中編寫**就好了!
dim n as long, m as long
private sub command1_click()
timer1.enabled = true
end sub
private sub command2_click()
timer1.enabled = false
end sub
private sub form_load()
n = 10
m = 0 '0代表紅燈亮，1代表黃燈亮，2代表綠燈亮
picture1.picture = vb.loadpicture("c:\紅燈亮.jpg")
label1.autosize = true
label1.font.size = 24
label1.caption = n
label1.forecolor = vbred
me.caption = "模擬交通燈"
command1.caption = "開始"
command2.caption = "暫停"
timer1.enabled = false
timer1.interval = 1000
end sub
private sub timer1_timer()
if m = 0 then
if n = 10 then
picture1.picture = vb.loadpicture("c:\紅燈亮.jpg")
end if
label1.caption = n
label1.forecolor = vbred
n = n - 1
if n = 0 then
m = 1
n = 3
end if
exit sub
end if
if m = 1 then
if n = 3 then
picture1.picture = vb.loadpicture("c:\黃燈亮.jpg")
end if
label1.caption = n
label1.forecolor = vbyellow
n = n - 1
if n = 0 then
m = 2
n = 10
end if
exit sub
end if
if m = 2 then
if n = 10 then
picture1.picture = vb.loadpicture("c:\綠燈亮.jpg")
end if
label1.caption = n
label1.forecolor = vbgreen
n = n - 1
if n = 0 then
m = 0
n = 10
end if
exit sub
end if
end sub
這道數學題怎麼做？求大神
證明題步驟過多，稍微簡略點啊。1 因為等邊三角形abc，所以 a c 60度，ac bc ab，因為be af，所以ae cf，所以三角形aec全等於三角形cfb，所以ce bf 2 因為三角形aec全等於三角形cfb，所以 ace cbf，又因為 bpc ace pfc，所以 bpc pfc cb...
