先插入三個textbox 控制元件 textbox1 textbox2 textbox3用於輸入a、b、c三個數
再插入兩個label控制元件label1、label2用於顯示最大值與最小值
最後插入一個button控制元件
雙擊button控制元件輸入以下**即可
private sub button1_click(byval sender as system.object, byval e as system.eventargs) handles button1.
click
dim a, b, c as integera = cint(textbox1.text)b = cint(textbox2.text)c = cint(textbox3.
text)if a > b and b > c thenlabel1.text = cstr(a)label2.text = cstr(c)end if
if a > c and c > b thenlabel1.text = cstr(a)label2.text = cstr(b)end if
if b > a and a > c thenlabel1.text = cstr(b)label2.text = cstr(c)end if
if b > c and c > a thenlabel1.text = cstr(b)label2.text = cstr(a)end if
if c > b and b > a thenlabel1.text = cstr(c)label2.text = cstr(a)end if
if c > a and a > b thenlabel1.text = cstr(c)label2.text = cstr(b)end if
end sub
可能有更簡便的方法

首先宣告變數abc
abc賦值 文字框.
在用判斷語句
判斷那個數值比較大...
判斷之後賦值abc為標籤的標題.
結束判斷語句
